Just took the Lollipop OTA update from stock 4.4.2. Upon completion my phone rebooted and is stuck on the LG boot logo. I tried entering download mode (holding volume up button and plugging phone into computer) but my phone doesn't enter it. Attempting to power off the phone doesn't work either, since the phone just powers off for a second and turns back on to the boot logo. I tried factory reset (power + volume down) and after proceeding with the reset the phone is still stuck on boot logo. I've tried the Linux method here ( http://forum.xda-developers.com/showthread.php?p=48765620#post48765620 ) but when I enter the first command (ls /dev/sd*) I don't get a sdb where the device is detected.
What should I do?
same problem here, not with OTA update.
No Factory Reset available, no recovery mode, only download mode. Same as you with Ubuntu i find nothing...
Flashtool stop working after S/W at 9 %
Stuck on the LG logo ...
Help needed :/
So I've wiped the Dalvik Cache, Data, Internal Storage, and System, but I forgot to flash before rebooting. Now it's stuck in the WARNING BOOTLOADER UNLOCKED screen and everytime I tried resetting to recovery mode it would turn off then turn back on at the same screen. ADB is not detecting the devices also. Is there anything I can do or is it bricked?

Boot into bootloader by holding down vol down and power together. The timing can be a little tricky when it is stuck or looping. Hold power until the screen goes dark and it tries to reboot, usually about 8 seconds. Then let go and immediately hit vol down + power together. Hold them until the bootloader screen comes up, should be pretty fast. Might take a few tries to get the technique down with it bootlooping.
From there you can flash firmware directly with fastboot, or boot it into TWRP to flash something from recovery. If TWRP fails to boot for some reason then fastboot flash it again.
It should not be a brick just from wiping everything. Well, just a soft brick anyway.
Thanks!
I was able to get into recovery!!
After performed wipe cache and firmware update with "Swift&Fast Slim B160 aio" ROM, the phone reboot and stuck at waiting for booting... ==> wait for 3 hours and still show the same as BOOTING.
Performed the factory reset by press Volume Up and Power, the Factory Reset is now stuck at 99%
Please help to the the phone back in working condition.
Resolved yet?
Possible idea
You can probably still load TWRP. Press and hold volume down + power at the same time to load fastboot mode.
ROM Flashing
Obtain a ROM of your choice, and note the location on your computer.
reboot your device into fastboot mode via one of the following options.
1. adb reboot bootloader (requires USB debugging to be turned on).
or...... power off the device then back on with 'vol up' + power button.
Wipe your device.
2. fastboot -w
Update your ROM.
3. fastboot update </path/to/your/RomFile.zip>
Your phone will update and automatically reboot into the new ROM. Try another ROM if Swift & Fast Slim isn't working. Your file could be corrupted.
did u get things fixed?
I had EliteTWRP 3.2.1-0 and restored the official rom from twrp recovery but it was stuck when trying to first-time configure the phone(it wouldn't get past the wifi setup). So I went into twrp to try and format everything and try to flash a different ROM and I faced another problem. Internal storage couldn't be mounted. I wanted to fix that by flashing the twrp 3.1.1 because that worked for me before. I got in the fastboot mode but it said that the phone is locked. That was strange to me so I tried unlocking the bootloader with "fastboot oem unlock [my unlock code]". The prompt came on screen asking me if i wanted to unlock boot loader and factory reset and I said yes. Then my phone restarted and is stuck on "Your device has been unlocked and cant be trusted. ...mod=restore page... Your device is booting now...". From that point it's stuck on that screen and I can't get into the recovery or fastboot mode. I tried the dload method(holding volume up volume down and power button) but that did nothing.
Please help.
Hi,
I did a TWRP wipe (everything checked) to prepare for a restore to stock, but my device is now stuck at the very first "Google" screen with the pad lock icon at the bottom. How do I get it to boot?

So since everything was checked, that means you wiped the system partition. The device will not boot if you do that unless you flash a factory image via fastboot or new ROM via TWRP
OK, I thought wiping /system would just bring it back to factory state. 2 questions now
1. How do I get to recovery when it's always stuck at the Google screen with no adb access? Would I have to wait for the battery to run out (hence turn off), charge it for a while, then use the buttons to boot to recovery, or is there a faster way?
2. I am actually trying to revert to stock ROM (downloaded at https://developers.google.com/android/images#angler) by following step 10 of the Heisenburg guide (https://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928) which advises me to use fastboot to flash the individual images. In my case, how do I boot to fastboot?
OK, so I managed to boot to the bootloader and run the following commands as per the Heisenberg guide (using the stock MTC20L firmware)
Code:
fastboot flash bootloader C:\angler\images\bootloader-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash radio C:\angler\images\radio-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash boot C:\angler\images\boot.img
fastboot erase cache
(above command is unnecessary on Android 7.1.2 and above)
fastboot flash cache C:\angler\images\cache.img
(above command is unnecessary on Android 7.1.2 and above)
fastboot flash recovery C:\angler\images\recovery.img
fastboot flash system C:\angler\images\system.img
fastboot flash vendor C:\angler\images\vendor.img
Everything was successful, and I did a fastboot reboot after that.
However, my device still doesn't boot up. This time. It's boot loops for a few times before turning off.
I tried booting up to bootloader with power/vol-. Curiously, I can now only do this when cable is connected. If cable is disconnected, the orange LED just blinks once when power button is pressed, and nothing happens. Once cable is connected, then I'm able to boot up to bootloader with the button combination. I then retried the flash process again, but still no go. I noticed after fastboot reboot that the orange LED blinked a few times before rebooting and boot looping.
Kinda stuck now, any ideas?
Try booting into recovery and doing a factory reset. I've had that happen to me a few times after flashing factory images and a wipe in recovery always fixed it.
Just for future information: if at any time the device is stuck in a bootloop you can get it to robot into recovery by holding the power and volume down buttons for 10 seconds, or get it to boot into bootloader by holding power and volume up buttons for 10 seconds.

Thanks. Booting into stock recovery shows an exclamation sign with "no command", since I don't have TWRP anymore. Would I need to first flash TWRP before I can do a factory reset?
I just tried flashing to the same sock firmware as before the problem happened (7.1.2 N2G47W) but still same problem. I notice that after the Google logo disappears and the screen goes blank, the orange LED blinks 10 times before rebooting.
Edit: Tried factory resetting in stock recovery (by holding down power button and pressing vol+), the rebooting after factory reset. Still getting a boot loop.
OK I solved the problem. Apparently if you reboot after the flash, you need to disconnect the USB cable, else it will boot loop.

brother help me! i am facing same issue
first little info abt my device.
my device was running on android nougat with twrp recovery installed but the device was not rooted.
so get back to stock and install oreo I followed every step given on http://www.androidexplained.com/nexus-6p-revert-stock/ but somehow my phone is stuck at bootloop with no recovery installed.
Please help me here.
As per the Heisenberg guide, if you don't install root (SuperSU or Magisk), TWRP won't stick, so you'll go back to stock recovery.
For me, simply unplugging the USB cable after rebooting after a flash solved my problem. For some reason, if the cable is connected during reboot, it would boot loop.
brother, somehow I managed to install twrp. but everytime I touch it 2-3 times the phone gets switched off.
then it keeps rebooting to 'Google' logo.
can you tell me what should I do now?
