Hello, I really need help, until yesterday my cell phone was working perfectly but suddenly it was turned off and now it does not turn on, but when I plug it into the power outlet the logo appears, but then reboots, and so on.

It looks like your phone is in bootloop.
Go to recovery.
Clean flash your rom after wiping everything except external sd(you will loose your apps and appdata).

Thanks for your answer
I tried that but did not enter the recovery mode, then install via fastboot the recovery twrp and tried again without success. I followed the steps to unbrick my cell but again I did not get a different result. Does the battery have anything to do?

Could you please describe in more detail?
Are you able to open fastboot menu by pressing vol down and power button simultaneously?
After opening fastboot menu and selecting recovery what happens?
Have you tried opening the recent TWRP (boot recovery) through fastboot command?
After keeping phone on charging is the phone showing charging animation(I'm assuming that the phone is switched off while charging)?

Enter the fastboot mode by pressing the power and volume keys down simultaneously and install the recovery then I returned to the menu of the fastboot and I wanted to enter the recovery and it stays in the bootloop, does not really try to launch the recovery via fastboot, when I get home Will be the first thing I try.
After leaving it a day connected to the power outlet does not leave the normal logo indicating that it is charging, in fact shows a warning that I had not seen before, it is a plug with an arrow towards 2 points (I suppose it is the outlet, when I get home I Update the post with the image mentioned)

So, my Maxx suffered a power button failure and I should be receiving my warranty replacement from VZW sometime in the next day or two. Other than the power button not working, the phone is functioning fine. It reboots, runs normally, functions perfectly. I'm running .215 rooted and I want to return the phone back to stock before shipping it back. Problem is I can't access Boot Loader, no matter what I try. It's like it's not there anymore and when I command the phone into it using quick boot, adb, or the built-in menu, the phone just power cycles off. Let me try to explain:
I have Quick Boot installed and I can use it to boot into recovery without a problem. If I try to boot into Boot Loader, the phones powers off and stays off.
I've tried adb shell with the same results. I can connect to my PC and command the phone using shell commands but usin the 'adb reboot bootloader' command results in the same thing: phone power cycles off and stays off.
Even though my power button is AFU, I figured out I can still access the main recovery menu (the vol down to choose, vol up to select one) by holding down the vol up/down and plugging the phone into a charger. Same thing: power cycles off and stays off.
* Funny thing is although my power button doesn't work, I can still soft reset the phone by holding the power button in and vol down - which is what I need to do to exit recovery or other menus I need to input to a prompt using the power button.
Anyone know of this happening? MY guess is since my phone starts and functions normally otherwise, the boot loader is still there in some form. I just don't know how to access it. Any help would be much appreciated.
I can confirm this app will reboot bootloader

Thanks Dave but not for me. Same result: phone power cycles off and just stays off when selecting reboot bootloader.

If there is no bootloader you won't be able to start your phone at all as its THAT what basically boots the whole hardware and software....
How about adb reboot bootloader or adb reboot recovery commands ?

The bootloader being the phone's "bios" is kind of how I understood it so I'm figuring it's still gotta be there. I just can't seem to access it or get to the "device/battery OK, device disconnceted" menu. I tried adb reboot bootloader and got the same results: power cycle to off and stays off. adb reboot recovery works fine.
Knowing this phone is going to be turned back in, is there any other way I could re-install .211 without having access to the bootloader screen?

Try the eternity project flasher or the motorola's rds lite if they will be able to put the phone to the flash mode as they do that automatically...

I posted a thread over at DroidRAZR.com and got some good feedback and troubleshooting help. It looks like the bottom line is the power button failed in the 'on' postion. One of the folks that replied to the DR thread caused his device to show the same 'AP Fastboot power-off' that I was getting by entering the 'Boot Mode Selection Menu' and holding the power button down while he vol+ to select AP Fastboot. It caused me to look a little closer at what the device was doing and that seems to be exactly what's going on - I powered th phone down using the Quick Boot app and was able to soft reset by holding down the vol- key by itself (didn't need to press power in conjunction). After it SR and i released the vol- key, the device rebooted by itself.
For your info, that thread is here: http://www.droidrzr.com/index.php/topic/3782-cant-access-boot-loader-menu-no-matter-what/
I tried working a thin piece of paper in around the button but no luck there.
I have already rooted my phone.
Actually i tried to backup my current ROM using ROM Manager, for that it reboot phone and get stuck for an hour. so i take out the battery. try to hard reset the phone it takes me to
Code:
Fastboot mode started
udc_start()
when i connect my usb cable it turns like below and nothing happening after that
Code:
Fastboot mode started
udc_start()
--suspended--
I also tried to get into emergency mode many times by volume up + volume down + Connect USB cable , but i get only LG logo nothing more.
Now i even not get into fastboot mode. i get only LG logo by holding any key combination.
Take out battery hold the buttons to put it in download mode keep holding while you put the battery back in

but to use the tool, The device must be in fastboot/bootloader mode.
Now i am not able to get fastboot screen also. i tried number of key combination while powering on phone. but all time i get LG logo nothing else.
hey, i've got a problem.
i'm running on Oreo 20r and installed Magisk using TWRP.
after rebooting, my device stucks in a bootloop.
is there any solution for my problem?
flashed magisk 17?
yes...
okay, actually I am currently stucked with the same issue too.
But I just got back my TWRP by doing following :
1) Boot into download mode (https://www.youtube.com/watch?v=_mycJDiFUPk)
2) Still in download mode, press and hold "vol down + power" (this time USB cable is still connected to PC and phone), it will reboot the phone, hold both button till you get in fastboot mode
3) once in fastboot mode, flash back TWRP as per unlocking guide
Now I am still in TWRP, hesitating what to do next. lol
Hope it helps a bit
it's not possible for me.
my device reacts to nothing... no keys, no recovery, no download mode
bootlooping like no tomorrow
maybe you can install KDZ-file using LGUP
or try to flash ZIP-file

I just clean flashed back Boombox 1.3 with magisk 16.0, so far booting up good.
I think you need to try again.
The download mode is a bit tricky, need to very fast hold long power button till off, once off, hold the vol up and connect the USB cable to PC. it should trigger the download mode
The bootloop that you have now, is just "LG V30 ThinQ" and the "unlocked bootloader" msg right? same as me I think

okay, let me try describe my steps in details :
1) Phone is bootlooping, USB cable is connected to Phone, NOT to PC
2) Hold down power button only till the screen becomes "black"
3) Once "black", quickly hold the "vol UP" and connect the USB cable to the PC
4) Now it should show the "download mode"
5) Without removing the USB cable, hold "power + vol DOWN"
6) Once screen becomes "black", release the "power" button, hold the "vol DOWN"
7) Until you see the "fastboot mode"
8) Now you can flash TWRP back using fastboot command from the PC
9) Boot back to TWRP
p/s : yes, the phone cannot be turned off, for long time, but it can be for a very short time. Need to use that short time to trigger all the keys
I have the same problem after flashing Magisk 17. I am in a bootloop between LG black start and root/unlocked bootloader warning screen.
I followed your steps 1-7 in a command line screen (as administrator) and it works but it seems that recovery flash is not working because the command line screen show me a very short time in the recovery flashing work (see attached image).
"fastboot reboot" returns me to the bootloop.
"Power Off" and "Restart" options in the phone returns to me to the bootloop again.
If I unplug the USB cable in the fastboot screen, the phone goes to the splash black screen and does nothing.
WTF!!! it's working.
i tried it one more time like you described it.
think i did it too slow before. booted into TWRP and the rest will be no problem (i hope so).
thank you sooo much!

how did you reflash Magisk 16 after?
@ChazzMatt HAve you looked at this? Some of are having issues after Magisk updated the Magisk app and then lost root...I guess we shouldnt have flashed 17, but when I try and reflash 16 I get the "updater process error" does that mean my only option is to format SD again, or do I have to start from scratch?

No, see the last few posts of WTF thread. You just have to uninstall 16 first.

I uninstalled magical 16 using the official uninstaller.....the device went into a bootloop I was able to boot to recovery but the data is now decrypted.....so tried to use OTG to restore a android backup and now I have a "the backup may not boot unless you change back to ext4"
I am at my wits end kindly help

I am stuck with the same kinda issue. By mistake restarted the Phone after wiping the phone for a fresh rom install. now i can see only the LG boot logo. There is no way to power off the phone. Pressed the power button alone for couple of minute but no use. Tried pressing the Vol Down and power to restart. I get a 1 sec window when the phone is off between the restarts but your method does not work in that short time. Is there a way to power off the phone ?
basically there is no Rom on it and does not detect on the PC when plugged in
Please help if you know anything

Try going to TWRP
1. hold vol down + power till it off
2. Once it shows the first on screen, release the power button and press back the power button (vol down hold)
3. A menu for factory reset will be shown, agree to it 2 times
4. Then it will boot to TWRP ( no data will be deleted )

I accidently flashed the lineage 16 recovery instead of lineage 17.1 recovery. I tried to install the 17.1 update through updater but my phone stuck into recovery mode. Neither I can boot into bootloader nor to android. I can''t flash anything. Power + volume down and connect the cable also not working to go into bootloader. Even bootloader option within the recovery also brings me back to recovery mode. ...adb devices command is also showing "device offline". Any help will be appreciated.
you should start from the beginning
is your bootloader still unlocked?

I can't go into fastboot mode. Is there any other way to check it?
Thank you @stukka2006 for replying me. I guess I saved my phone. So here what I did-
1. Extracted the stock firmware (Luckily I had one but can be found in the forum) and copied the dload folder to sdcard (as I was not able to access internal storage). (@stukka2006 your hint to start from the beginning)
2. Power off the phone and pressed Both volume buttons + power button simultaneously. After the vibration I left the power button while still holding both vol buttons till software update screen appears. But software update failed. So I just touched the reboot now option. The phone rebooted to fastboot mode.
3. I installed TWRP but was not able to reboot to recovery through commands and system reboot command brings me back to fastboot mode. So I again power off the device with cable connected and pressed both vol buttons. This time phone showed recovery screen (Should have worked with normal button shortcuts also, I guess) and I flashed the rom and rebooted normally.
Everything is working fine now except that I lost the data.
Happy you got all clear my friend !!!

Sometimes it is that the screen is blank but TWRP is there though, when you are presumably in TWRP, connect your device to the PC and try with ADB commands to see what happens, let us know.

Not this way, press the buttons to supposedly enter to TWRP, do all of them blindly. Start with pressing the three buttons simultaneously for about 12 seconds (this will power off your device) then immediately press the volume up + PWR button for about 7 seconds (to enter to TWRP), then type the commands.
Pay attention if something is displayed in your screen and if you hear some sound when connecting to PC.
