What is the most common question after we root our Android phones? The most important reason behind rooting our phone is the desire to try different custom ROMs. If you have a low-end phone which is not that popular, you would find a few or no custom ROMs for your device. On the other hand, if you own an immensely popular smartphone like the Samsung Galaxy S3, the plethora of choices will are sure to pull you down into the world of confusions. While for some people are fond of trying all ROMs just as a habit and some, those like me, have to frequently flash their phones to write an article like this, most people wish to make a perfect choice when it come to custom ROMs and stick with it for some time.

Seeking perfection in this world of imperfections is a wild goose chase but there are still chances that we can find one that is near perfection. Every ROM developer tries his best to cook his ROM in a way that might taste good to all, but human beings have always been known for their variety of taste, liking and preferences. If you have been suffering due to fast battery drain on your current ROM, your foremost preference while going for another ROM will be good battery life. In the same way, some people prefer beauty, some fast performance, while other want a feature-packed ROM for their phone.

Keeping such things in our radar, it was almost impossible to find out one ROM that is best for all. In fact, no custom ROM can be the best. It can only be better than other in some aspects, or worse than some in others. What is the best ROM for you simply depends on your preference and requirements. As Shakespeare says: “There is nothing good  or bad in this world, but thinking makes it so.”

At Droidviews, it is always our priority to address things that matter to our visitors most. And that is why we often come up with tips and tricks and how to guides. This is not for the first time that we have published the Best Custom ROMs article, in the past we have tried to cover almost all popular Android devices. This time we have picked T-Mobile Samsung Galaxy S3 SGH-T999 at the request of one of our visitors who requested us to write a best ROM post for this phone too. So we are here!

Things to Do Before and After Installing a Custom ROM

The ROMs listed below are in no particular order, so it should not be taken as a countdown. The reviews and selection is based on the author’s experience and it may be that you have a different view. We have listed what we think are one of the best. What is really best is upto you to decide.

How to Install Custom ROM on T-Mobile Galaxy S3 SGH-T999:

Download the preferred ROM and Google Apps (if applicable) from below and follow the instruction below carefully. But as I said above, your phone must be rooted and CWM Recovery installed on it.

  1. Download the ROM and GApps files in zip and copy it to your device by connecting it to computer using a USB cable.
  2. Turn on USB  Debugging Mode on your Galaxy S3 SGH-T999 from: Settings> Developer Options.
  3. Make sure your phone has a good battery level, if not charge it now.
  4. Backup your contacts, messages, and apps etc. These nice free apps will make the backup job very easy.
  5. Turn off your phone and reboot your phone into ClockworkMod Recovery mode. If you do not now how to do it, here it is: press and hold the Volume Up+Home (center) keys simultaneously and then  hold the Power key. Keep the three buttons pressed till the screen turns up, the Samsung logo blinks for two times. Release the power key now but keep other two keys pressed till you see a list of options in blue text on black background with Android bot.
  6. In the Recovery the touch mode does not work, so you will have to use the Volume up and down keys to scroll and highlight and the Power button to select an option.cwm-recovery-menu-GALAXY-S3
  7. The first and most important thing is to backup your current ROM. Scroll down to “backup and restore” option and select “backup”. It might take a few minutes for the backup to complete.
  8. When it is done select go back option and choose “wipe data/factory reset” option and wipe it.
  9. Then go to “wipe cache partition”  and wipe it.
  10. Finally go to “advanced” option and “wipe dalvik cache”.
  11. Return back to the main menu and select “install zip from sd card> choose zip from sd card” and select the ROM file that you copied to your phone in Step 1.
  12. When the ROM is installed, go back and install the Google Apps zip package the same way you installed the ROM in Step 11.
  13. Finally, go back to the main menu in Recovery and select “reboot system now”.

Remember that the first boot after installing a new ROM takes much longer time than an usual boot. Sometimes it takes up to 10 minutes (maximum), so be patient. In case you phone does not boot properly and you are stuck on bootanimation even after 10 minutes, long press the power key. If it does not work for you, remove the back cover, pull out the battery, wait for a minute, reinsert the battery and try again. If you wish, you can go back to your previous ROM any time if you have made a back up as told in Step 7.

 1. PAC-Man ROM

Developer: klin1344


ROM Review

PAC is the abbreviated form of ParanoidAndroid, AOSP (Android Open Source Project) and CyanogenMod. That is to say that the PAC ROM for your Samsung Galaxy S3 SGH-T999 is designed to give you an ultimate mobile experience by combining the best features found in the ParanoidAndroid ROM, CyanogenMod 10.1, and pure Android features found in Google Nexus devices.

There are many great ROMs out there, with the more popular ones being AOSPA (ParanoidAndroid), CM10.1, and AOKP. Being all great ROMs, it is sometimes difficult to choose which one you want to run. Why choose when you can have all three? P.A.C.-Man ROM is combination of all three ROMs, so you don’t need to keep switching or deciding between which one to flash. Get all of the features in one ROM!

The PAC-Man ROM  is currently the only ROM that integrates the Pie Launcher features recently introduced with ParanoidAndroid 3.0 ROM. Besides, you can also choose from different layouts like phone, phablet and tablet. It is a hybrid ROM and known for unlimited options for customization. During the two days of continuous use, the ROM was found to be beautiful, smooth, fast and yes, battery-friendly. Since it is basically a CyanogenMod ROM, you can apply themes to it which can be downloaded from Google Play store.
