LG’s latest beast with powers like never before, the LG G3 features a 5.5 inches True HD-IPS display, Qualcomm Snapdragon 801 Quad-core 2.5 GHz Krait 400 processor, Adreno 330 Graphics unit, 13 MP high-res Camera with 3 GB RAM for better performance and smooth user-interface. The device was released during May 2014, proving itself to be a strong contender against all other high-end flagships including Sony Xperia Z3, Oppo Find 7, Samsung Galaxy S5 and the HTC One M8.

One of the top-rated and reliable Custom Recovery for Android, i.e TWRP Recovery, has been released for all the variants of the LG G3 by the famous Codefire team. All set and ready to be installed and hence we’re here to guide you through the process of installing TWRP Recovery and to Unlock LG G3 using Bump!. Now, you must be worrying about “bump!“? Bump! is another very reliable program to allow flash any boot images to your LG G3 with a locked bootloader. So, now if anything that has to be flashed to the G3 needs to be bump’d. Following from now on, most of the ROMs you download will be pre-bump’d to ease the process.

We greet the team Codefire for this impressive work and all the LG G3 users, for now, the flashing process will be made a hell lot easier.


Rooting and installing custom recovery/ROM may harm your device in unknown ways if followed incorrectly. Understand the risk and proceed thereafter.

  1. I just did everything right on my lg g3 d855, but when i reboot into recovery, it says fastboot mode started. i don’t know why it is not going in custom recovery mode. Please help me

  2. I thought I did but when I reboot the phone with buttons pressed for recovery mode it gets stuck on black screen with white fastboot mode text at the top.

  3. Great guide! I have a problem using this method. I have LGG2 D855 10E running stock 4.4.2 (Kit Kat) rooted (I bought it new a few months ago). When I try to boot into recovery I get a black screen with white text at the top saying fastboot mode. If I remove the battery it reboots into android fine. I cannot access TWRP. Please help!

  4. my phone is not rooted and i simply flash the phone using marshmallow image and lg flash tool. it get 36% and it hangs (not responding) i didn’t remove the cable and waited 30 min. after, it restarted and it fails

  5. Hey, i have a lg g3 vs985 with lolipop 5.1.1 and i’m trying to install TWRP but display boot error

  6. I have accidentally flashed my lg g3 d850 [email protected] Now i am trying to restore my phone back through lg flash tool. but i have problems with flashing when it reaches 82% and the phone restarts. flash tool ended with a massage “Fail to get Mini OS Status. Fail!!! Factory_BootComplete() 00000064. Error: Fail! .”. The cell phone restarts again and again just showing me LG logo nothing else. need help…..plz

  7. . flash tool ended with a massage “Fail to get Mini OS Status. Fail!!! Factory_BootComplete() 00000064. Error: Fail! .”. The cell phone restarts again and again just showing me LG logo nothing else. need help…..plz

  8. I take it the D851 is out then? I have it rooted specifically for this process and to unlock the phone afterward, but without a custom loader I can’t upload the files into the firmware to change the provider information. I’ve read that works, but can’t even be fully sure of that. If anyone knows where I need to pick up on the search to enable an unlocked recovery menu like my Nexus 4 had stock, please let me know, never had to install it before as most phones I’ve messed with came with a loader that wasn’t locked to start with.

  9. How can i install TWRP on D855 HKG version with KitKat version install, current software version v10o-hkg-xx, seems very uncommon could not find much on it on forums ?

  10. OK, so any suggestions as to how get out of this mess. The article didn’t mention this only worked on KK. How do I fall back to a working recovery?

  11. SO I have the problem also. Whenever I boot into recovery I get a black screen and the light flashing blue and red. Sits there forever. So effectively I have no recovery. I can reset via battery and get the phone working but while I have a rooted phone it effectively has no recovery. Running stock lollipop

  12. This doesn’t help get back to recovery. I am already rooted on Stock lollipop. I tried Flashify and installed but keep getting Boot error.

  13. Sorry late reply, I flashed stock recovery and got phone working again however I have tried the bump method again to unlock the bootloader but get the same error then flashing blue red LED 🙁

  14. But i have the same Problem as “Guest”. I tried several Lolipop Versions (From D85520A to D85520I) and several methods to flash custom recovery.

  15. So if you start your phone in recovery mode (Holding Power and Vol Down Button, waiting till Logo appears, shortly release the Powerbutton and press it again) there should be a message on the screen e.g. “Secure booting error…”. To boot your rom, just detach the battery and start the phone again.

  16. Everything went fine installing the recovery for my 855 then when I choose the factory reset the led flashed red & blue. I pressed the volume up now phone is DEAD!?

  17. Hi, I am new to LG so this may seem a very noob question. So I have a D855 G3 model and I am currently on official 5.0 stock firmware. It is v20f-EUR-XX. What should I do in order to have a v20f stock ROOTED rom? Thanks

  18. Any idea how to twrp a D858hk? There are some Chinese forum threads that have a twrp recovery for D858. Wonder if that would work. Google muzisoft D858HK twrp.

  19. Hi,

    I wanna know if this will work for the Hong Kong variant D858HK. My phone is already rooted.

  20. i type in adb shell, but i says device not found. i enabled usb debugging and copied the image. help!

  21. Hello… i would like to know if its possible to go back to stock recovery?
    Im asking this because i need to take my phone to warranty (due to several overheating).

  22. The img file for the VS985 is apparently corrupted. SO I cannot install TWRP now. Has this been reported before?

  23. Hello,
