Things to Do Before and After Installing a Custom ROM + Troubleshooter

Before-and-After-Installing-a-Custom-ROM

Android being an Open Source operating system for mobile phones, offers limitless possibilities of optimization and customization as per your requirements. Half the charm of an Android phone lies in the root-based apps, beautiful mods and patches, and custom ROMs. If you have not rooted your phone yet, believe me you are not getting the most out of it. Rooting offers many advantages indeed but, at the same time it is also a little risky as it breaks into the wall of security build by the operating system.

According to a survey, 80% of Android phone users live happy with an unrooted device and the reasons for this are various- some people think of it as a sort of criminal activity, some are afraid of losing warranty, some are afraid of bricking their phone, while most people do not even know about the existence of a term like “rooting”. If you are one who has enclosed himself in side that great wall of security and have doubt in mind related to rooting, do not forget to read the following article:

Anyways, the procedures like rooting and installing a custom ROM is a bit risky and it’s true, but if you go through it carefully, no harm will ever done to your Android device. People brick their phone because they make some mistake. That’s the way accidents happen! As an Android blogger, I have to root, flash stock and custom ROMs, install mods and patches almost everyday. And believe me all my device are pretty healthy and sound. If you understand things, take precautions, create backups and do things carefully, you’ll never be caught into an uncomfortable situation.

Here are a few tips that that will help you keep things under your control and you will be able to not only keep all your data safe, but also restore your device to its normal condition.


Got TWRP Recovery on Your Device?

Do you think you are well familiar with all the features, functions and possibilities of the TWRP Recovery? Think again! Read our detailed and in-depth introduction to the Team Win Recovery Project: Click Here


Ensure Decent Battery Level

battery_full

Whenever you have to install a custom ROM or mod or mod on your phone, try to be ready for the worst situations. Just imagine you are installing a ROM and your phones turns off in the middle of things due to low battery! You will have to charge the battery with an external charger because your device will not be able to charge the battery because it does not have any ROM that makes this function work. In such a situation, you will not be able to restart the procedure or even restore from a backup Therefore, it very important that your phone is amply charged before you set out on the adventure.

Backup Your Apps, Contacts, Messages, etc.

Whether you have rooted your phone or not, always backup your apps, contacts, call-log, messages, bookmarks, calendar entries, etc. The best way is to schedule regular backups, preferably to external storage of your device and your computer. Here are some nice free apps that will make this task easy for you.

Enable USB Debugging Mode

usb-debugging-MODE

The term “debugging” is used in connection with development. Putting your Android device in debugging mode prepares it for direct connection with your computer via a USB cable without notification or read log data. Flashing/installing anything that does not come under official method, might be regarded as a development activity. It’s another thing that you did not developed the ROM you are going to install, but still it is a work of custom development.

That’s is why, whenever you perform any such task, it is highly recommended that you turn on the USB Debugging mode from Developer Options under Settings of your device. On Android phones with Jelly Bean 4.2 and higher, the Developer Options are hidden by default and can be made to show by tapping 7 times on “Build Version” from Settings> About.

Further, you should also install the appropriate USB Drivers on your computer as you can need them anytime. To download the compatible USB Drivers for your phone/manufacturer, visit our USB drivers collection page.

Backup Your Phone’s IMEI (Samsung Users Only)

imei-number

When you install a custom ROM on you phone, sometimes it happens that the folder that stores your phone’s IMEI (International Mobile Equipment Identity) number is wiped. As a result, your phone’s IMEI number is lost it does not receive network signal. To avoid this happen to your phone, do not forget to backup the “efs” partition.

To backup your Samsung Galaxy phone’s IMEI or EFS data, read our guide by clicking the following link:

How to Backup and Restore EFS Data / IMEI on Samsung Galaxy Devices

In case you have a low/mid range Galaxy device from Samsung, you can use an app called Galaxy ToolBox for the purpose.

Enter Recovery Mode Easily:

If you are a hard-core Android enthusiast who likes to play with new ROMs and mods every now and then, be careful or you might damage the hardware keys of your Android phone. Since booting into recovery mode of a phone or tablet requires hard-pressing of certain combination of hardware keys, doing it frequently can have a negative effect on the functioning of these keys. I have experience it myself when I had a Galaxy S. Fortunately, there are several apps that can make booting into download, bootloader or recovery mode very easy without being cruel to the poor hardware keys.

Here are some good free apps for you that will let you do this without touching the hard keys. If you have installed a custom ROM, you need not install any such app separately as most ROM developers integrate the boot options in the ROM itself. Besides, we have an vast collection of methods of entering Fastboot, Bootloader, Download and Recovery modes on most Android devices.

Backup Current ROM (Important)

Being able to install a custom ROM on your Android phone means that you have installed custom recovery like ClockworkMod or TWRP on your Android device. Well, having a custom recovery on any phone is a great advantage. It can perform all tasks done by stock recovery while adding lots of other useful options.

clockwormod-recovery

One such great feature is its ability to backup the whole ROM, custom or stock, on your phone’s internal or external storage. You can back as many ROMs as your phone’s storage can afford. I strongly recommend that you always keep a backup of your phone’s original/stock ROM. Before you install a new custom ROM, always create a backup of your current ROM. Scroll down to the backup and restore” option and backup the ROM to the internal or external storage of you device. If you select “backup”, the ROM will be saved to internal storage. To save it to external SD card, select “backup to external sdcard” option.

All backed up ROMs are saved on a folder called “clockworkmod” on your device’s internal or external SD card, depending on what location you chose while creating the backup.

It’s is always better to store the backed up ROM on the external storage because sometimes the phone is caught in a bootloop, or the screen goes into a frozen state, or you may experience lags, or anything, and decide to reset/wipe your phone to get it back to normal. In doing so, all data stored on the internal storage is deleted. In certain situations you might have the opportunity to backup your data but in some cases you might not be able to do that.

How to Restore a Previously Backed up ROM:

As I said earlier, you should always keep a backed up copy of the rooted stock ROM on the external SD card of your phone. If the phone does not have an external SD slot, you can save the backup to the internal SD card (not safe though). If you frequently flash an AOSP, AOKP or CM based ROM, always keep a copy of the Google Apps flashable zip saved on your phone.

So if you installed a custom ROM and you are having problems with it or you just want to go back to the previous or any backed up ROM, do this:

  1. Boot you phone into CWM recovery mode
  2. “wipe data/factory reset”
  3. “wipe cache partition”
  4. Then go to “backup and restore> restore”, select the location (internal or external) of the backup.
  5. Select the file and confirm your choice by selecting “yes”.

So, this was a detailed tutorial to help you land safely whenever you install a ROM. I have tried to be inclusive but if feel that something is missing, do not forget to share with us via comments. I believe the tips given here will prove useful to you. Thanks for being with us! For more Tips & Tricks on Android, take a tour of our other tutorials.

Installing a Custom ROM

 
  • Venkatesh Ramanathan

    I want to clean installation with custom rom, i wanted to use the 16gb(except few gb for custom rom) bcos the custom rom files takes probably 200mb, and after installation may be it take 2-3 gb i guess…is there any way to maximum space in my phone?? may be a 13gb usable storage out of 16gb?? Please someone help me…Am using Samsung galaxy s3 LTE version phone.. Thanks..Ram

  • http://www.droidviews.com/ Rakesh

    You must have made some mistake. Install the ROM again but this time do not forget to wipe data, cache partition and system before installing the ROM. Also, you did not mention your device model.

  • MariaKristine Ilagan

    it is my first time to customize my ROM and I didn’t wipe the data and cache but i did the back up and restore and the install .zip from SD card, now my phone is still in recovery mode, is it normal? I mean does it really take that long? i think its been 10-15 minutes, did i do something wrong? or its okay bc for the first timers, it usually takes long? pls reply and answer thank you…

  • ch kranthi

    I have google for cwm recovery for my phone but failed to get the appropriate one. can you help me to find right cwm for my mobile (Celkon A95)
    thank in advance

  • http://www.droidviews.com/ Rakesh

    Since you are trying to install a custom ROM using stock recovery, you are getting that error.

  • ch kranthi

    My mobile is “Celkon A95″ (Indian company) I dont have any Clockworkrecovery. I have rooted my device. when I tried to install custom rom from sd card by pressing “Volume up key+Power key” it says signature verification failed. I tried different zip files (custom roms) but same message “signature verification failed” please help me.

  • http://www.droidviews.com/ Rakesh

    Which recovery are you using?

  • ch kranthi

    can any one please tell me how to disable “signature verification”
    Thanks in advance

  • Ramon Bautista

    Hi there. If i may ask. I have a thl w100 phone which is a china brand, and i have a firmware version of thl w100 (130912) but the custom rom that i want to flash is based on thl w100 (130711) with this should i change my firmware or is it ok to flash this.. thank you to those who can answer. :)

  • omar alkhateeb

    Hey,I just so u didn’t realize I’m new to Android, and got my nexus 5 a week ago. So I might have lots of questions on customization, and it seems like u know lots about this stuff. So can I like ask u any question about Android. Is so what’s the best way to contact u. Tnx

  • omar alkhateeb

    Tnx dude, I followed u

  • http://www.droidviews.com/ Rakesh

    Yes, copy it it to the computer too. Before installing the ROM, wipe only data, cache and system. Do not touch the storage and it will be alright.

  • omar alkhateeb

    OK thanks for the quick reply, but I don’t have an external storage, cuz I got a nexus 5. So u meant to move it to computer then?

  • http://www.droidviews.com/ Rakesh

    The backup is saved in a folder named CWM/TWRP on the internal or ext sd card. If it lies on yhe internal storage, move it to the ext sorage first. You can also keep a copy of it on your computer.

    Usually, the data factory reset option in cwm/twrp foes not wipe the internal storage but it is good to ttake precautions.

  • omar alkhateeb

    Please answer my question, I just backed up my current rom, and I was wondering if I flash another ROM, I would have to factory/reset. So wouldn’t this delete the backup of the ROM I just did. So do I have to place the backed up ROM to an external drive?

  • Vitor

    i’ve just made a homemade factory cable and it did worked!! the phone turns on again… but i’m still stuck on that unlocked bootloader rebooting… i’ve tried to flash some bunch of stock and custom rom’s… but nothing came along… just the reboot loop! i’m really tired already!

  • Harsh

    Hi, I have flashed the phone but its not rebooting it showing green lead (charging) how long it will take to reboot

  • Ryne

    Thanks, I got the ROM and Google apps to work by reinstalling them then it worked fine.

  • ZAM

    I have done root+CWM based on the instruction and tried to install CM 11, but unfortunately it doesn’t work. After reading some other web site it says require CWM 6.0.4.3 minimum version for Kit Kat, but the installed version along with root is 6.0.3.1. Now, my backup image is hanging. Where can I get the latest version of CWM and how do i upgrade it?

  • http://droidviews.com/ Rakesh

    Try disabling the signature verification option before restoring the backup. It should be fixed.

  • Ryne

    Can someone please help me, I tried to install cm11 m2 release on my galaxy s3 t-mobile and every time I try to install the rom or the Google apps it says E: cannot open … (bad) installation aborted. Now none of my recent backups work either they all say md5 mismatch! Please help, I don’t know what to do.

  • http://droidviews.com/ Rakesh

    Yes, it’s a serious trouble as the device does not have a removable battery. If you somehow manage to get it replaced, the problem can be resolved.

  • Vitor

    Yeah… it just light the green led but it does not appear to be charging. and it does not show the battery charging… and i can’t turn on the phone even in fastboot mod… i am in serious trouble!

  • http://droidviews.com/ Rakesh

    That’s was a great mistake. One should always ensure ample battery before performing such things. Did you try connecting the device to a charger?

  • Vitor

    The battery of my Razr xt925 discharged during the installation process… what do i do??

  • http://droidviews.com/ Rakesh

    Copy the ROM file to ext SD and install it via CWM or TWRP.

  • Ȑɱ Ƭaylor

  • Ahmadovich (R4bia Edition)

    Actually, I found one. I turned off my phone for about 5 days and then I tried it again and restored the original OEM TouchWiz and it was smooth as butter. I couldn’t stay for long with TouchWiz so I flashed the “stable” release of Cyanogenmod 10.1 (4.2.2) and it was lightning fast El7. :D

  • fractalbit

    Same problem here. Tried to instal CM, Omega rom and they freeze every minute! I am following all the good advices here to wipe data/cache/davlik/system before installing the new rom. I cannot understand why i cannot install a new rom without problems after this! Did you find a solution?

  • http://droidviews.com/ Rakesh

    Okay, try this: pull out the battery and put it back after a minute. Take out the micro SD card and download another ROM: http://www.droidviews.com/best-custom-roms-for-samsung-galaxy-s4-gt-i9505/

    Copy the ROM file to sd card and reinsert it in the phone. Now boot in CWM and you know what to do then. Next time be careful while doing such things. :)

  • Marcos

    Hello! I need some help! I could not make a back up and did the wipes and all but the CWM does NOT recognize my ROM zip!!! Now im stuck at the CWM without any ROM! What can i do!^? I have a S4 9505 and my CWM is v6.0.3.2. Please help!

  • http://ishq-e-mustafa.blogspot.com/ Abdulmusawwir Qadri Barkaati

    oh…k
    Thanks!
    :)

  • http://droidviews.com/ Rakesh

    Nope. Wiping SD will delete all data from user memory, not system memory. It’ll not delete the installed ROM or CWM.

  • http://ishq-e-mustafa.blogspot.com/ Abdulmusawwir Qadri Barkaati

    Lemme get this right, as I don’t wanna mess up my first time..
    [I wanna flash carbon] || [GNex doesn't allow for an external sd card]

    Copy zip file to sd card,
    Boot into recovery,
    Wipe Data, Cache, Dalvik,
    Flash carbon rom zip file,
    Flash Gapps zip file,
    — At this point I will now have Carbon ROM —
    ….
    Boot into Recovery,
    Go to mounts & Storage,
    wipe sd card.

    Right?
    Then what? Coz If I get this correctly, After doing the above… I won’t have anything on my sd card… and I’ll need to flash a rom again.. and I won’t be having CWM anymore, right?

  • http://droidviews.com/ Rakesh

    Install the ROM first and then wipe the sd card.

  • http://ishq-e-mustafa.blogspot.com/ Abdulmusawwir Qadri Barkaati

    Yes, I have CWM, After I’ve done that.. the sd card will be completely, including no system files, right?
    Then how would I install a ROM? How would I boot into recovery to copy the zip file(s) as I would’ve erased everything?
    PS: I’ve a GNex JB 4.3, Wanna flash my first custom ROM

    Thanks for your quick responses!

  • http://droidviews.com/ Rakesh

    You can find another option for that. If you have CWM, go to “mounts and storage” and wipe sd card.

  • http://ishq-e-mustafa.blogspot.com/ Abdulmusawwir Qadri Barkaati

    oh… k.
    What if I want to erase my sd card completely?? How would I do that?

  • http://droidviews.com/ Rakesh

    No, it just wipes the system apps, audio and configuration files. System here means the partition of your internal storage that keeps system file.

  • http://ishq-e-mustafa.blogspot.com/ Abdulmusawwir Qadri Barkaati

    Installing a Custom ROM -> Step #4 -> Go to mounts and storage and “format system”
    Won’t that delete everything on the sd card… including the zip file that we copy?

  • Karthikeya Pervela

    Hai ism using samsung galaxy ace s5830i recently i have flashed it with jellyblast custom rom after installing that i lost my imei i tried galaxy tool box and efs pro tools also nothing is worked pls tell me a way to backup and restore imei of my galaxy

  • Raghav Das

    Thank you for the answer.

  • http://droidviews.com/ DroidViews

    The line you have quoted, I am talking about avoid using apps that backup app data too. Backing up the APKs and restoring them does not pose any problem.

    http://www.droidviews.com/backup-apps-contacts-logs-messages-and-settings-without-rooting-your-android-phone/

  • Raghav Das

    In this article, under the heading “Avoid Restoring Apps & Data Backed Up on Another ROM:”, you have mentioned as follows: “In fact, all such backup apps (Titanium Backup, for example) are meant to restore data on the same ROM on which the backup was created. Due to system file discrepancies among different ROMs, restoring apps and data this way might make your phone laggy and slow. Therefore, I recommend you to avoid doing this for better performance of the new ROM.”

    My question regarding this is “Is the above also applicable to simply backing up APK files of installed apps?”

    If the answer to this question is “No” (I mean to say, if that’s not applicable to the activity of simply backing up APK), then can you suggest the best way of backing up the APK files of installed apps and restoring after restoring a custom ROM?

  • http://www.twitter.com/hEbBoOo Ahmadovich

    The international version Galaxy S III. Tried CCyanogenmod, Ugly Muiu (or whatever) even the laggy touchWizz. All suck and still I have the freezing technique, but today it became less.

  • http://droidviews.com/ DroidViews

    Try some other ROM. What device do you have?

  • http://www.twitter.com/hEbBoOo Ahmadovich

    After installing ‘LiquidSmooth’ “thousand” times, my S III is so slow and sometimes freezes I don’t know why? I want to go to the stock ROM. I also want to release it from its freezing mechanism. Also, my phone go really hot at times I think of the working of “SetCPU” and “Seeder”. I already removed them but still there are some issues.

    Question about IMEI saving.
    It says to use X-Plore File Manager, which I did, and it says to copy EFS folder to external SD and have a copy on the computer which I did too. Now, when i open the EFS folder it is EMPTY, I mean there are no files at all in it, is this normal?

  • http://droidviews.com/ DroidViews

    If you have backed up EFS, your could restore it to get back IMEI otherwise it is very difficult, but not impossible, to get IMEI back. To reboot the device, try wiping data factory reset and cache partition in recovery mode.

    Hi Jordan, the loss of EFS/IMEI data issue is associated primarily with Samsung devices and that is why you are unable to find the EFS thing on your Defy. Just backup your current ROM before installing the new one.

  • http://droidviews.com/ DroidViews

    It might be due to a bug in the nightly version as they are experimental in nature. Try the stable release to ensure if it is really a Kernel issue. Also, has your device a custom kernel or the stock one?

  • Shahid

    Hi, i just recently started with this whole custom roms installation and i loved it on my s3 but i’ve ran into a major issues and i need some help. i installed the cyanogenmod 10.1 nightly build rom and everything works fine but i cant hear anything when making phone calls. now the call goes though but i cant hear anything such as the dial tone or the person speaking to me. I’m thinking its something to do with the kernel but even so i dont know where to get the right kernel.
    If i cant fix this in the next few days im going to try going back to the stock samsung rom. hopefully that would fix the problem.

  • http://droidviews.com/ DroidViews

    Hi Anand, there is nothing to be afraid. All you need is to be careful and stick to rules. A custom ROM might be a good solution to fix the issue you are having. I am not sure if custom ROMs for the device is available or not but I can suggest you to try these apps to boost RAM:

    Hi guys, I’ve a doubt with sd card partition(increasing internal memory)…

    Suppose I partition my sd card to ext4 with 1048MB size and then flash a custom ROM…if I have to flash a new ROM again, will that sd card partition get wiped? do i have to partition my sd card again if I’ve to flash a new ROM? kindly clarify…

  • Jason K

    yeah i can see it, but if i open the “clockworkmod” folder i cant see a single file there. I read in forums that it uses adb to pull it out. Do you know the command? thanks :D

  • http://droidviews.com/ DroidViews
  • http://droidviews.com/ DroidViews

    The location depends on your selection of storage while backing it up. CWM creates “clockworkmod” folder on internal and external storages both.
    Can you see the backup file when you try to restore a ROM?

  • Jason K

    hi guys i backup the ‘original rom’ using cwm, but i cant find the backup file on my phone. Do you guys know where to find it? i already search into the clockworkmod folder in the storage but its empty

    Do full wipe before installing rom, if still its giving problem…use stock kernel. Dont flash any mods and check

  • gh.rohit

    1. Flash ICS gapps
    or

    2. Clear data of apps
    or
    3. Remove and add google account again

    Well I’m glad that it was an honest mistake. I honestly thought that it was misinformation in the title. I’ll be sure to read it! Thanks for posting!

    You know, when I read your comment on on my phone, I was surprised. I thought what this man is saying! But when I open the article on my desktop, I was even more surprised to see just a paragraph and not the full article.

    Thanks for notifying. It was due to some technical error and has been fixed now.

  • Malik DrumFunk Martin

    So where’s the actual “things to do” part?

  • Yan D. Sky

    thanks for this..

    I already tried all ways to update my Ace 2 GT-I8160, but the attempts have always failed, and Odin 1.85, when the word came modem, appeared the word failure. So quit updating it.

  • http://droidviews.com/ DroidViews

    Try these:

    Uninstall and install drivers, reboot PC and phone then try again.

    Try another USB cable

    If the above does not help, it might be a ROMs issue. Try this:

    You can just flash the Kernel but do a dalvik cache wipe before and after flashing it.

  • Afzart Feizaireey Abdul Ghani

  • http://droidviews.com/ DroidViews

    In an AOSP ROM, you will not get S Pen features. Install the Ultimate ROM:

  • simpharm

    ok..thanks a lot…

    This kernel does not work with AOKP and CM Roms. It’s only for Samsung JB.

  • http://droidviews.com/ DroidViews

    Okay, install this via Odin: http://vln01.helochat.com/tourist/speedmod-kernel-n7000-jb-k5-2-Odin.tar
    It’s a safe kernel that disables MMC_CAP_ERASE bug
    It would also root the device. Try and let me know.

  • simpharm

    okay.but how to exclude mmc cap erase kernel? can you name a safe kernel pls?

  • http://droidviews.com/ DroidViews

    Well, I know dozen of people who have rooted their Note and installed custom ROMs. You can try too.

  • simpharm

    its the same application that told me I have defective chip.after jb..everywhere in blogs the bug is related to ics kernel.I am confused.

  • http://droidviews.com/ DroidViews
  • simpharm

    thank u…ys..I flashed german JB with odin.since my phone is jb now, is it free from bug? can I reset it? how can I know whether a kernel contains mmc cap erase?

  • http://droidviews.com/ DroidViews

    Hi,
    I would suggest you not to flash any leaked kernels or kernels based on sources where MMC_CAP_ERASE is present. Have you installed the latest JB?
    This is a firmware bug and is related to ICS firmware for Note.

  • simpharm

    sir,
    my note gt n 7000 when checked with chainfire says that it has got the emmc bug chip..can I root my note? pls tel me how to root it safely

  • Tushar

    Great guide. I have learnt a lot from this site. I rooted my phone galaxy s2 after I read your post ‘To root or not to root’ and now I’m running supernexus rom. Thanks a lot for such guides. I visit the site daily and I always find such interesting articles. Keep up the good work.

    Hi Kalin,

    Thanks for your still informative and nice observation. Actually, I just tried to share has always worked for me since I first stepped into Android. However, I agree with what you say and I will gladly update the article pretty soon.

    Thanks and regards!

    Very good article, Rakesh and thank you. I visit your blog quite often and find it very informative, well designed, with competent articles and everything is put in order so one could easily find his way. If you just allow me to add some more info: Wipe data/factory reset wipes /data and /cache, too. With this procedure /dalvik is also wiped because it is located in the /data partition. So it might not be necessary to wipe these partitions separately. But It is very important to wipe the /system partition, too because not all custom ROMs include “format system” script and system files from the previous ROM might remain in the new one. That is why it is good to do it manually before flashing the ROM of your choice. The last procedure leaves the system with no ROM at all so one would not be able to boot until a new ROM is flashed. Additionally some devices use the /preload partition to store system apps in order to save some system space. So it would be a good idea to format the /preload as well.
