My LG G5 went into Fastboot mode for no reason, it was fine one minute and the next time I pulled it out of my pocket it had entered the Fastboot screen, I have tried the following to no avail:
- Removed battery waited a minute and reinserted....opened in boot screen menu,
- Held volume button and power button and got into factory reset function and pressed yes to reset twice....it then returned back to boot screen.
- Plugged into PC, and typed Fastboot devices in CMD, phone is recognised here,
- USB debug will probably not be activated on my phone either.
- Is this a Battery problem?
- Is there a way to reboot without wiping all data?
Thanks in anticipation of your help.

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 a LG D805 locked to Telcel in Mexico and tried to SIM unlock by unlock code.
After SIM unlock, I can't get the local mobile operator's signal and the the problem was started there.
Rooted by ioroot24 and
SuperSU, FreeGee,Titanium Backup Pro were installed
installed CWM and ROM manager and backed up files.
Then flashed D805_panama_stock.zip for testing.
Failed to get the signal. and then flashed D805_10A-724_RADIO.zip
Tried to wipe data / cache by factory hard reset.
After factory hard reset, Everything's gone and Just LG logo boot loop.
Now,
Press and hold power, then I can turn it off.
When g2 is turned off,
Press and hold Volume + button and plug in USB, then can't enter Download mode
When g2 is turned off,
Press and hold Volume - and Power at the same time until LG logo's on and release them and
Press and hold them again and then press Power buttom 3 times , then Factory Hard Reset.
again enter into LG Logo boot loop status.
When g2 is turned on,
Tried to communicate thru ADB but not listed.
When g2 is turned off,
Press and hold Volume + & - and Power button at the same time,
can get emergency mode when the touch panel doesn't work.
Tried to do it by using Ubuntu's terminal command but the problem is now that
the computer does not recognize g2.
while installed KOUSH universal ADB driver.
Is there any ways to have PC to recognize g2 ?
Thanks in advance any clues and advise to catch g2 by PC in this case.
Hey Guys, so i never usually post because i can usually solve my own problems, but i think this time i've out done myself.
So last night when installing CM12.1 using TWRP my xperia Z2 everything was looking rosy. Then when I tried to turn the phone on to boot the first time it gave me just a single little vibe but would not turn on.
I've tried ALL combinations of button resets - Nothing
I've tried to re-flash a stock image using flashboot - Nothing - it won't recognise flash or download mode when i plug it into my computer while holding down volume down
I've tried holding the volume up button while plugging it into my computer to try FASTBOOT mode - Nothing - the blue LED on the top comes on, but neither OSX or WIN7 recognises anything has been plugged into the computer and it doesn't register on ./fastboot devices
So have I actually properly ****ed my device? Or am i missing something?
Any help would be so massively appreciated. Like i said, i usually never ask.
Did you try another cable? Blue LED is good, so fastboot mode should work.
When it would be bricked, there would be no blue LED...
Did you look into device manager on WIN7? Any device like "S1boot" or "Sony ADB Interface" there?
Sony logo showing up, when turning the phone on?
Try "fastboot reboot or "fastboot reboot bootloader" even though "fastboot devices" doesn't show up as anything (weird). It should boot back to bootloader and register your device. This happened to me once.
I think it's "fastboot reboot-bootloader" and i think it won't work...
Try
Try holding the power button and volume up button in until it vibrates. Then you should be able to hold power button and volume button to get to download mode. This works on mine when all else fails, lol.
Nexus 5x, not rooted.
Last night I glanced over and it was powering itself down. I tried to get it back on by holding the power button a bunch. Eventually I decided to just go to sleep and left it charging in case the battery was dead. This morning I got it to power up by holding the power button for 30 seconds. It booted, got to the unlock screen then rebooted.
I can fastboot (down and power, 10s) and get into the recovery menu. I wiped the cache. I did factory reboot a few times. After the first time I got into the device setup but rebooted after connecting to wifi and "checking connection". Now after another factory reset is gets to the colorful circles bit then stops (turning off).
Went for the re-flash stock image route. Start adb as root (Linux). I tried flashing but it says the device is locked. Tried to unlock using `fastboot oem|fastboot unlock` and both fail with "FAILED (remote: oem unlock is not allowed)". Given that I can't get the phone to boot, I can't access dev options.
Am I screwed? Is there any way to fix the phone?
Thanks,
Hi All,
I'll explain this as clearly and simply as possible and hopefully someone can help
My oem 3T ran out of power, plugged into dash charger and no led, power button held down for 10secs and entered fastboot, got to some options by holding power and volume down, but none of the recovery,wiping cache,delete everything options worked (would always go back to fastboot)
I ended up following the unbrick tutorial on here (link - https://forum.xda-developers.com/one...us-3t-t3515306)
and got it back to factory state, HOWEVER, I cannot update the OS without it going into fastboot, if I THEN turn off and turn back on holding volume down it doesn't take me back to all the options I had (wiping cache, reset system settings ect) but shows me the android logo/loading screen with something like this in yellow text:
>>>> changing to aging
then I'm back to the original state before I tried to update the OS.
Any help would be MASSIVELY appreciated!
I think I've discovered the problem! - my volume button is stuck on up also!!
didn't realise this with the power button held makes the phone enter fastboot mode is any case
