If you are an Android user, you might be find yourself in situations when you might want or be forced to do a hard reset on your device. Sometimes, your phone might start behaving weirdly after installing an unsupported app. Whether you are a new or a veteran Android user, there are certain things you must be familiar with.

Performing a factory reset and booting your device into safe mode are among such things. Using the safe mode on an Android phone or tablet, you can easily diagnose if a certain issue on it has stemmed from a misbehaving app. When booted into Safe mode, you Android device only shows the stock apps. Since all third-party apps are disabled, you can easily uninstall an app that may be causing a conflict or software problem from Application Manager.

Just about an year ago, we did a detailed guide on booting a range of Android devices into safe mode and today we have come with a beginner’s tutorial on how to perform hard reset and boot LG G3/G2 into Safe Mode. If you are an LG G2/G3 user, you have to do a factory data reset after installing the stock firmware manually to ensure bugless performance. This can be done using two methods— using the Factory data reset option in device settings and using the hardware keys of your phone.

Hard Reset LG G3 /G2 from Settings Menu

Warning: Do not forget to backup your phone’s data before doing a factory data reset. Here’s our guide.

Performing a Factory data reset restores your device to the original factory settings as it comes out of the box. It also deletes the data like installed apps, contacts, messages, images, etc. present on the internal storage. It does not, however, affect any data stored on the external SD card. Now here is how you can hard reset your LG G2/G3 from device Settings:

  1. Tap the Menu key from Homescreen.
  2. Select System settings> General.
  3. Now scroll to PERSONAL
  4. Select Backup & reset option.
  5. Tap Factory data reset> Reset phone.
  6. Select Erase everything.
  7. When the warning window prompts, tap OK.

  5. G2 is a hell… I would suggest every one to never buy this handset.. Yesterday I visited market to see if there is a cure available… And I found that they already had more than 15 sets with the same problem.. I went to a popular shop and said that I have a set, and its touch is not working properly since i changed the ROM.. the shopkeeper said which handset? G2? I asked how do know? he said its obvious! lol… Shame LG

    my problem is the phone who does not go in download mode
    i enable usb debugging and i turn off the phone and then i press the volume up button and connect to usb but he does not want to
    help pls

  10. Its not hard resetting… tried many timed… powered off and on holding power and volume buttons etc… followed everything written on this page… no reset option appears… it did appear yesterday when I tried that before I wiped it.

  11. Sorry for being such a dumb.. I am trying all this for the first time, and creating more trouble trying to fix it.. What should I do now?? 🙁
    touch was faulty in custom rom, so I started all this, and now I am like: Custom was much better than this stock… 🙁

  12. Darn it! Suddenly the Support tool got stuck at 99% (picture is attached)… but I didnt interfere the installation on device. It kept on installing, I waited for about 5 min and then It powered on… but its touch is not working at all… I tab at the center and it responses from a corner.. now I tried to enter the recovery mode by same method I used to do before wiping.. but its not working…. I think the TWRP recovery mode has been removed..

  13. Hey I tried something weird and it worked! In LG support tool it again gave the same error (remove battery etc),, i clicked the retry button and immediately pressed the power button.. while support tool was verifying windows OS, I again loaded the download mode by pressing volume+ key… And it worked the stock firm is being installed now… without even the USB debugging enabled..

  14. Since you phone doesn’t have external SD card slot, you can use USB OTG instead. Your G2 already has TWRP recovery (I guess), just copy the SuperSU zip and the custom ROM file on the OTG, plug it to your phone, boot into recovery mode and install the files. Flash SuperSU first so that your phone has root and then flash the ROM.

  15. USB OTG will make the USB drive appear as an SD card? Connecting through a USB OTG will boot the recovery mode right?

  16. when I try to restore to its stock by using LG drivers and LG Flash Tool on download mode.. an error shows up “sever unavailable.. disconnect usb and remove battery etc…”
    While the drivers were installing, I found that CDC serial driver failed to install… is it because USB debugging was not enabled? or should I try to find the driver??

  17. I dont think usb debugging was enabled before this happened, i disabled it in developers options… and its not turning off.. I keep the power button pressed, it turns off and then immediately turns back on automatically… cant save the power, I am keeping it on charger since this happened, so that its battery does not die.. but its heating up now

  18. Don’t worry. It’s not so serious a problem. Just do as I told you above. I have been through similar situation quite a few times.

  19. Look, if you want to restore to stock, follow thins guide: http://www.droidviews.com/how-to-restore-lg-g2-to-stock-firmware/

    However, before you attempt the guide, make sure that USB Debugging was enabled on your G2 before it got into bootloop.

    Since your device does have a microSD card, the easier solution is to get a USB OTG. It will work as an external flash drive for your phone. Copy the SuperSU and ROM file to it and then install both the files in TWRP.

  20. I now connected my phone to PC, pressed powered button again and then volume up key… it has now entered the download mode.. but its stuck at 0%… What now??

  21. but dear it does not support external SD card, its LG G2 D802… And How to enter TWRP? I am unable to enter into the recovery mode… when I press “power+volume down” button, it restarts, and then again LG logo appears, LED starts flashing (Changing colours).. Nothing else happens

  22. Shitt! please help i have done something bad 🙁
    In advance wipe I checked all boxes… when I reboot it said “seems like u do not have your device rooted, install superSU? I accepted to install then the device turned off.. and its not booting again :((
