Boots into bootloader automatically every time after rooted? - E 2015 Q&A, Help & Troubleshooting

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.

Power Button Stopped working.

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!

LG G5 [Über Bricked] help!

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

Cannot boot to recovery or fastboot-rooted LG V30+

Hi all. I just recently unlocked the bootloader and rooted my LG V30+ following the WTF guide with no issues. However, I installed a "Hide navigation bar" module in Magisk and now the screen is in accessible and I can only reboot the phone. Since I have TWRP installed, I cannot boot into bootloader holding down the volume down and power buttons. Any suggestions? I cannot use adb becuase it says that the device is unauthorized since I cannot allow permisions on my screen ( cant see anything on screen atm).

You can boot to TWRP with hardware button dance.
8 sec Power + Vol-, and when it shuts off, release both, immediatly press both again (at the same time), and as soon as the LG V30 logo appears, release power and press/hold it again.
Should get you to the factory reset menu, confirm twice with "yes" (navigate via vol/power buttons), and TWRP should boot fine.
Might take a few tries to get the right timing for that

For that, remember the annoying bootloader unlock warning is part of the boot sequence.
Or do a Master Reset and start over.

Thanks!
EDIT: The post you link finally got me to boot in recovery. Thanks so much!!!
Cant believe it was that picky!

Ignore bootloader unlock warning. It's just part of the boot sequence. Maybe it's considered the "logo". Don't let it freak you out.

I must have done this button dance 25 times now, it just goes between unlocked boot warning screen and LG SlimQ screen, over & over again. Still no luck.
eff you LG...

Suggestion... Why not boot to TWRP with fastboot commands like in the WTF instructions? Then reboot to TWRP from within TWRP (reboot to recovery, from Recovery) to make sure you are then on your phone TWRP and not your PC TWRP.
Then after you root, use the recommended power menu app to never have to worry about it again.
If you already have root, then just go install that right now.
ADVANCED POWER MENU (root needed)

The person who started this thread couldn't do that because they installed something which messed up their screen. They couldn't see the Advanced Power Menu, nor see ADB/fastboot. So they HAD to use the hardware button dance...
Really no one else ever has to do that, except T-Mobile H932 users who don't have fastboot flash commands.
Hi Chazz, been unlocked and rooted with TWRP installed for months now. Wanted to just refresh us998 H, since something in Anxious mod may have been causing some issues. Wiped cache & dal, flashed the zip, flashed magisk 18.1, then rebooted to system. Magisk showing as not installed. Wanted to get back to recovery & reflash magisk....except now I can't for the life of me get back in there. New PC build here, nothing set up yet to be able to do fastboot stuff. Dang this is frustrating.

In Oreo, did you enable USB debugging and then allow ADB from this PC? You have to install ABD drivers, LG drivers, fastboot drivers, and connect via good USB-C cable. If so go into ADB folder, hold-shift and right click to 'open command prompt here', and type "adb devices". If the PC recognizes your phone then it should say "adb xxxxxxxx authorized". Then type "adb reboot recovery" and it should boot into TWRP. If not then repeat everything and type "adb reboot bootloader" to go into fastboot or bootloader mode. In this mode you can type "fastboot flash recovery twrp.img" where the TWRP-xxx-xxxx.img has to be renamed into TWRP.img before hand (else you have to type the full TWRP file name. The TWRP file has to be in the same directory as the adb folder
I'm good turns out I ended up using my old PC, was able to adb recovery mode, installed 19.2 magisk over 18.1, which then showed up as being installed on the phone and root working. Guess I'll be keeping my old puter around for a while...lol

Factory Reset/Wipe Data in Locked State w/o working screen

Hello there!
I received my Poco F1 yesterday and set it up with all the apps and settings I wanted to use (including WhatsApp and Signal Backups with private keys). Unfortunately the phone didn't survive the day - after less than three hours the screen went black and since then stayed like that. Additionally, it heats up like nothing else whenever it is turned on. I tried holding power, power + vol up etc. - the phone seems to reboot and booting up again but the screen stays dark. As I live in the EU and bought the phone here I contacted the seller, who agreed on shipping a new device, but I still have to send back the old and broken one. That's where my problem begins:
- There's already a load of private data and information on the phone I do not want to give to the seller and everyone who might gets the phone in their hands afterwards
- The phone itself still seems to work. I can reach it via adb, reboot to bootloader, reach it via fastboot and reboot back to the operating system
-
Code:
adb shell pm clear xxx
and
Code:
adb shell am broadcast -a android.intent.action.MASTER_CLEAR
both yield a SecurityException
-
Code:
fastboot -w
yields
Code:
FAILED (remote: 'Erase is not allowed in Lock State')
- I do not want to unlock the device, as I don't want to give anyone any reasons to refuse this guarantee case.
Do you have an idea?
Thanks in advance!
Your warranty doesn't void on this device. It was confirmed by CEO Jai Mani. If you still concern for warranty you can later relock it. Use this command - "fastboot oem lock". So stay calm and try this.
Hi and thanks for your suggestion! It looks like I don't have any other choice. Could maybe anyone guide me through what happens when (my screen is completely dark after all )?
So, I can easily go into fastboot mode by doing a "adb reboot bootloader". I will then use the unlock tool to unlock the phone. Does anyone have an exact idea of what will happen next?
Will it reboot automatically or do I have to do it by myself? Will it stay in fastboot mode?
Will it try to set something up or anything else I should not abort after rebooting? How long will this take approximately?
Will all data be lost by only unlocking the phone or will I still be able to "adb shell" into the system after unlocking (w/o accepting the computer's key again of course)?
In case I got stuck, is there a reliable way to go from anywhere into fastboot mode again (to "fastboot -w" and relock)? Which button combo can I use for "completely turn the phone off" - is it the "3min power button" or the "power button and volume up" one? After "fastboot -w", how does the phone behave? Does it reboot automatically and does it do something after that I should not abort? If yes, how long will it take approximately?
I see that these are kind of difficult questions for people who could see what's going on, but after all it's pretty important for me because I can't
Thanks for your help!

First unlocking bootloader takes 3 days. Then after unlocking your all data will be wiped and you automatically boot into the system. If anything goes wrong you can use Mi flash tool to flash miui again in fastboot mode. The most reliable way to boot into fastboot mode is to boot into recovery by pressing volume+ button + power button at the same time and then boot from there. I have never encountered that prob so I can't surely tell about that. Please tell me if it works.

As you seem to be interested in only removing the data (not recovering it), the bootloader unlock will wipe your phone completely and it will automatically boot again into the initial Setup screen where the first screen will be asking for the country. At that point simply power off the phone and you will be done. I am saying this from the personal experience of unlocking the bootloader of this phone.
Hi and thanks for your help! The unlocking & relocking process was completely flawless. Vol + Power Up seems to be the "Turn off"-Combo, by the way
Thanks again!

Realme 5 Looping after locking bootloader

Hi. I know this is my mistake. I just wanted to ask if there is any way for my Realme 5 RM1911 to be fixed. I used In depth test apk to unlock the bootloader. For those who doesn't know, it is necessary for Oppo and Realme Phones to use this to fully unlock bootloader to access flashing. After a failed installation of TWRP, I decided to just give up and continue using it. After a while my device is not certified on google play store. So after that I decided to go to my unlocked bootloader and lock it again using fastboot flashing lock. After that the bootloader ask me if i really want to lock it and chose yes. It booted and after that it is just displaying "The current image (boot/recovery) have been destroyed and cannot boot"
turning on and off and showing just like that. I cannot afford to fix it because Im just a student. I can't also access the stock bootloader eventhough I try pressing Power + Volume down or Volume Up. The only response is when I push power + volume up and down altogether, it is still connecting to computer but adb and fastboot doesnt work. Thank you very much for help.
