Hey all
I have the G5 Eu 850 variant and my power button has seemed to of died! (this may of happened from dropping my phone)
I want to get a warranty repair but i have the official bootloader unlock and custom recovery. How can i go about removing custom recovery and locking boot loader without the need to use the power button??? if i flash the latest kdz via lgup will that clear the recovery and make it stock without the need to power my phone up at any time? then use the fastboot oem lock command?
hope you can help!

We must find a way to unlock the bootloader.
How could we do?
Someone could help solve this problem?
I haven't seen anything that can do that and LG's boot-loader unlock tool only supports european G4 phones. I tried the Developer Options > Enable OEM unlock, but got a security error screen on boot when I tried flashing.
I was able to root with kingroot and install twrp which was the next best thing. You have to turn off the phone, then hold power + volume down, then release power for a second then when the lg logo appears then keep holding them both. In the factory reset menu, select (yes) perform factory reset twice and it will boot into twrp where you can flash roms and make backups.
When I installed TWRP and tried to boot into TWRP I got the "Secure booting error"..
How did you get into TWRP?
I use the H340AR

Hi, I just unlocked the bootloader and rooted my XT1527 with twrp and supersu successfully (Android 6.0). However, the phone boots into the bootloader automatically every time by pushing the power button only (without pushing the volume down button). Also, charging with the phone off will bring up the bootloader again. Did I screw up somewhere? How can I make it to behave like it used to be? Thanks in advance.
Found the solution. "fastboot oem fb_mode_clear" fixed it.
Hello, after flashing a .575 rom on my xperia z2, I wanted to install a new kernel but a problem occurred: when I shut down my phone the Sony logo reboot constantly and I can not access the flash mode so I do can not unlock my bootloader. Do you have a solution to the problem when I bootloop turn off the phone and to access the flashmode? To switch the phone I have to plug it in, wait until the logo of the battery reaches and press power. I have access to recovery if needed (I'm now in .570 with a backup but the problem is still present)
Sorry for the bad english I had to use google translation to some sentences
You can not go into flash mode if the phone restarts constantly.
If you have recovery installed, as you wrote, Just flash rom from there, after entering in recovery
If not:
Try to keep both the power button on the phone with the volume down until you feel the vibration. After that, phone is switch off. Run Flashtool and flash stock firmware.
You don't need flash mode to unlock bootloader, just unlock it using fastboot
fastboot -i 0x0fce oem unlock "your unlock code"

Hello dear all,
I have managed to brick my LG G5 like an Old Mill Brick.
My LG G5 (lg g5 h850 titan) does not boot. It comes with an error message as follows: Your device is corrupt. It cannot be trusted and will not boot.
What I already did to Unbrick:
Tried to unlock the OEM. No way from USB Debugging as I cannot go into OS.
Tried unlock the OEM from fastboot (remote: oem unlock is not allowed).
Tried to flash some things like (boot.img, system.img) even adb sideload stuff. Nothing works. I cannot flash anything because (flashing not allowed) because OEM is not unlocked, but cannot unlock the OEM because it is not allowed. WHAT in the brick do I have to do now?
Cause of the brick of the bricks:
The LG G5 was on LineageOS, all stable and solid. When a prompt appeared telling me that I have to update the OS. So I was like yeah ok whatever. BUT, it did from OTA. I also had a specific LineageOS APP for updating the OS. After some minutes (updating) I immediately panic and started worrying. BECAUSE, I knew what time it was (my device is dead). I wanted to turn my phone off but it was already in Recovery (TWRP). So I just hit cancel. BUT after booting up the LG G5 that corrupt device error appeared and I cannot manage to get rid of it.
Please I need your help! I also watched and tried (2+ hours) to manage to solve this via Google and different links and Unbrick guides but nothing happens. I cannot unlock the OEM because it is not allowed. I cannot flash anystuff because the OEM is not unlocked.
Update: So, there is no Recovery System present. No stock Recovery, No TWRP. And I think no OS either. So only thing that is present is the bootloader screen smh.
Can you still get to TWRP?

No If I hold the volume down button and Power and when the LG Logo appears I release the power off and press again nothing happens. It goes again into that error. I can go in bootloader but can't do anything with adb or fastboot.
I think TWRP is gone too :/
You should be able to get into download mode. Hold the volume up button with phone fully powered down. While you hold the volume up button insert the usb cable. Then you can flash the full system kdz with LGUP

Thank you very much! I didn't know I could do it in anotherway. Will definitely try this! Thanks again!
My Samsung A50s (507FN) is not booting and I want to try rooting and flashing custom rom. But when I flash TWRP with MAGISK am getting error of OEM LOCK.
Please help me unlocking the bootloader in order to flash custom rom.
Note that I am not able to turn on device.
Get back to official rom first, and enable OEM Unlock. If, there any option to unlock bootloader using volume up + volume down and insert USB cable then after warning appear on screen, press and hold volume up, to unlock bootloader.
But i dont recommend you to unlock the bootloader, because it may cause your device dead if selected file not compatible or wrong selection file.
Just back to official rom, first. (same binary version is recommended)
