Bootloader is unlocked in LG G4c!

-> Requirements:
(1) LG UP
(2) Device must be: LG G4c

Fixed: Brightness.

Make sure you are on Lollipop firmware.

(1) Download this patched aboot file: http://data.vineethp.me/android/mps/qualcomm/LG-G4c/Misc/Btlunlock/Lollipop/
(2) Connect your phone to the computer. In command prompt, type "adb shell".
(3) Transfer the aboot file into /sdcard/ folder.
(4) Type "su" to enter the root shell. Then type "dd if=/sdcard/aboot_5120.bin of=/dev/block/mmcblk0p5" (without quotes).
(5) Restart your phone by typing "reboot".

You have unlocked your bootloader!

Refer Notes for more information.

-> Notes:
1) The aboot_5120.bin is the patched version of aboot partition of your device. Secure boot validation has been patched such that secure boot is always valid, so you can flash your own TWRP and Custom ROM.
2) Don't upgrade to any updated version of Android if you get any through OTA update. It might brick your device.

Hi all,

Just to remove the last few doubts, I've checked on my phone the partition layout.

The aboot is /dev/block/mmcblk0p5 .

It's for a French Open H525n.

That link is for twrp. My understanding is that bootloader needs to be a lot first before you can install TWRP. Or am I missing something? So does this unlocking method work on MM

This link is for a TWRP flashable MM stock LG rom.

You first must downgrade your phone to LP n10f. Unlock bootloader and install TWRP.

Then you can flash this linked MM rom zip.

Warning guys!

This bootloader unlock is for Lollipop version n10f.

Check in you phone paremeters the software version you have at first.

If you are not on n10f, download the following .kdz file and flash it using LGUp.

Hello mate.
I want to downgrade from MM to LL, but LGUP does not recognize my device. And since I do not have root, I can not edit the device name in / cust. I think I've read all the posts on the LG G4c, and I can not find the solution. What can I do?

Hello, you need to install the G4c dll for LGUp to recognize it.
