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?

hi, did youmanage to solve this problem? I am aving the exct same problem. Disconnecting the ucb isnt working for me
So I was installing magisk with the help of twrp, but I was having a difficult time finding the magisk zip in twrp. Had rebooted the device and booted to fastboot and recovery mode for around for more than 30 times. Now, this is the situation of my device: its right now switched off. I can enter the twrp, i can access the fastboot mode but if I try to normally switch it on, the boot is stuck at the Asus logo. Nothing happens after it. From the Asus logo, i am able to swtich it off and move to fastboot and twrp. Help me please.
Maybe flash decrypt zip ?
Try this. go back to twrp, abd instead of reboot phone, press power off. then press power on button manually. Works everytime for me
So I was installing twrp and everything went right until it didnt boot to the recovery and from then it keeps booting to lg logo and bootloader warning forever.
I know I can install the stock rom with lg up by I cannot enter download mode since the phone isnt technically turned off. Does anyoene have a solution.
It's my main phone and I literally cannot afford a phone right now.
A way to turn it off would be the solution. Battery was around 70% so it will take a long time to actually have 0%.
Update: I got to the fasboot menu from where I can run fastboot reboot recovery after installing twrp again. Now I have some mounting issues and I cannot flash any zip without entering bootloop. Im trying to use the shut down menu of twrp to try to enter download mode.
2nd Update: solved using lg up with the latest android version.
I am on the latest EU weekly rom rooted with Magisk. Everything was going fine. I decided to reboot my device because my Messenger's dark mode was loading weirdly again. As I rebooted, it went to recovery mode without me doing anything. I tried to reboot it again but it wen to recovery mode again. The unfortunate thing is it's not even booting completely to TWRP and just stuck on its logo.
What do I do to fix this?
Did you find a solution? the same happened to me today, rebooted the phone and it's now stuck in fastboot but i can access recovery
I successfully rooted the phone and installed magisk etc. but I want to further and wanna mess around a bit. So I need TWRP to back up my everything. However, whenever I flash TWRP to both slots phone deletes OS or TWRP claims so. Therefore I flash the OS and do all the things over again and the cycle continues. What can be the cause for TWRP deleting OS or saying so. Is it can be caused I flash the wrong TWRP? I used tool all in one to only boot to twrp but it just stucks me in the fastboot logo and nothing happens for long time. I know when flash it it boots in seconds.
And for FTM mode I try to enter the ftm mode but it stucks on boot logo and doesnt bring any chinese characthers again for long time. What can be the cause?
All the helps would be appreciated,
Thanks in advance.
