So I unlocked my bootloader on my Huawei P8lite ALE-L21 yesterday and flashed twrp recovery. Trough twrp I tried to root the phone by flashing.. It sort of failed and I got into a bootloop.. Then I tried to get out of the boot loop by trying methods I found online. Other's did nothing so I tried to flash boot, recovery, system images.. Now it won't get in a boot loop but I get the huawei logo for 3 seconds and the phone turns off. I can only boot in bootloader.. Is there any way I could still make it work or is it completely lost now?
Update: I flashed Boot.img and recovery.img again and now im stuck at the point where huawei logo appears, but not turning off phone. I am also able to get to recovery now.
Update2: I flashed a different system.img now and suddendly the phone started working.. Problem solved I guess.

Probably issue with your downloaded image make sure you md5 check them
I decided to unlock the bootloader so that i could flash TWRP recovery but after unlocking the bootloader on my device, it has been stuck on the logo screen with "powered by android" under it. I have tried using fastboot to clear userdata & cache but that just leads to my phone again being stuck on the logo screen. The device also can't boot into recovery. When I chose to power off in fastboot it causes me to be stuck on the logo screen. Any help is appreciated I am on android oreo btw
Did you try a back to stock zip? go to fastboot and run flash-all.bat, while your device is plugged in ofcourse.

Let me guess.
You unlocked the boot loader and flashed TWRP and now you are looping, right?
There is no compatible TWRP that is compatible with Oreo on this phone.
You cannot leave TWRP installed. You can only install it along enough to get the recovery to boot.
You then must flash the stock boot image.
I had this problem tonight also. In my case I suspect it had to do with the install of magisk in which I checked both boxes and patched the bootloader. on reboot I was stuck on boot. Just wanted to add my solution. I got the pie back to stock zip here https://forum.xda-developers.com/essential-phone/development/stock-7-1-1-nmj20d-t3701681 then I put it into the adb folder and ran the flashall.bat script. I tried the no wipe one and it saved my information. very happy I didnt have to resetup my phone in the end.
did you remember to flash a stock boot.img before flashing magisk (to clear TWRP?)
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?

My device is stuck at fastboot, I messed up bad. I had a backup from OOS from 9.0.6, I upgraded to 9.0.10, I flashed TWRP installer and Magisk, then the phone would boot up to the lock screen but immediately say powering off. So I tried restoring the device and then I got an error. Now it can only boot to fastboot mode and is only recognized as a fastboot device by my computer. Any one know how to help?

Double posting isn't the most surefire way to get help here, just wanna point that out.
I love you
I was stuck and my phone didnt turn off tank you so mutch
Please HELP
I am writing here the whole story.
I unlocked the bootloader of my Asus zenfone max m1 (3/32GB) using the unlock tool which I downloaded from Asus's website.
Then, I went to fastboot mode and flashed TWRP recovery and then tried booting into it through the cmd screen using fastboot boot twrp.img command and it worked.
Then I followed a really good tutorial and flashed the pie firmware, Pixel Experience and magisk and ZIPs in order.
And it showed no error, everything was fine and then I clicked on the reboot system button, it rebooted the system but the phone was stuck at the google logo with a loading bar and didn't go beyond that even when left for 30 mins and I tried rebooting the phone multiple times and that did not help. the phone was stuck at the google logo every time.
Then I turned off the phone and tried going to TWRP to flash the pixel rom again but the phone only went into fastboot mode, it never booted into recovery even though I tried multiple times(I was trying to boot into the recovery through the volume and power buttons, not through fastboot mode).
I flashed the phone's recovery multiple times and also the boot image (I even tried flashing the stock recovery) but the problem is that everything goes fine in the terminal, it shows that it flashed the img file successfully and it is finished but the commands like fastboot reboot recovery don't work at all, they all just reboot the phone normally and the phone just shows the ASUS logo for few secs and then turns off.
Note: I used fastboot erase commands to remove the pixel experience rom and now I'm only left with a phone which boots only into fastboot with no rom and I don't know about the recovery because it shows that it flashed but it never opens.
Hi
I am having a similar problem in that I can oly get into recovery mode with adb reboot recovery. I researched and tried all possibilities with the phone key but I can only go into bootloader mode.
After flashing recovery successfully (?) I can only boot the phone normally and that seems to reinstall the default recovery manager.
While researching I found that there are some discrepancies with the ID out there. While my phone is a Zenfone Max (M1) with the ID X00PD some places (TWRP) confirm that but others refer to Z555KL.
Did you get any further?
