Device Boot Looping/Soft Brick - Essential Phone Questions & Answers

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?)

Stuck at "Google" screen after TWRP wipe

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?

Can't flash recovery, boot into recovery or do anything.

Hello!
I just repaired the display of my OP2 and when turning it back on it went straight into bootloop. Only showed the OP Logo and android on the bottom. ADB obviously doesnt work and tried to all partitions via fastboot to get fresh start. After completely resetting I unlocked the bootloader again just to be sure. Then I tried to flash twrp 3.2.1-0. it say dtb not found error. I tried a twrp 3.0.0-0 and it said succesfully flashed but after automatically rebooting the screen just turns black. I can the into fastboot mode or into bootloop can't do anything else. I also tried the MSM8994DownloadTool.exe but it just returns into bootloop again or turns black.
Help pls

BRICKED ASUS ZE552KL unlocked fastboot mode not found cant install recovery

I used TWRP to flash official lineage os 16, it was working fine but a new update came and it booted directly into recovery to install firmware. It could not install it . I was stuck in recovery. when I flashed my backup of lineage os it indicated some error saying /system not found. I then searched over and run some command in unlocked bootloader fastboot to fix it. I found a thread on xda to fix system error in TWRP and run cmd "fastboot erase system "also erased boot and recovery then clean installed boot and recovery but my bootloader was gone.
Now it's stuck at powered by android only and with no asus logo. I used asus flash tool with raw image file
to get into stock rom but failed.
THE UNLOCKED BOOT LOADER IS LOST
when I press volume up and power key the system bootloader comes but the deafult bootloader and the unlocked screen message is not showing.
and when i press only the power button there is no asus logo the phone is stuck at screen saying "Powered by android"
please help !!

[SOLVED] Unable to enter TWRP/Stock recovery and can't boot into system

Hi,
I have been using my P Smart (FIG-LX1) for a while with LineageOS 16 and decided to move on to Android 10. Installed LineageOS 17.1 (found it on this forum) and pph-Magisk 20.3 for root - it did work, but the system was unstable so i decided to try AOSP 10.0 instead. I entered TWRP, wiped cache,dalvik,system and data, flashed the ROM, gapps etc. It was advised to now flash stock recovery and use it to do a factory reset - and now i'm stuck here.
After flashing the recovery_ramdisk img the phone stopped being able to enter any recovery at all. The system itself does not boot (stuck on the "Your device has been unlocked (...) Your device is booting now..." screen forever), the recovery never appears (previously in the start screen with 'unlocked device' warning it used to suggest pressing volume UP to enter recovery, now it only shows "Your device is booting now"). As i can still access fastboot, I tried flashing TWRP again - the TWRP splash screen does appear, but the phone gets stuck on it. Also tried flashing another system's img - nothing changed.
Is there anything I can do or did i just brick it completely?
Thanks for help!
SOLVED:
Apparently running fastboot erase on system and userdata partitions made me able to boot into recovery/erecovery again. I do have another problem now, but it's not connected with this one so I will create another thread for that.
Could you try help me? I can't even get ADB to work anymore

Question Help with Nothing phone stuck in Fastboot mode (A13 Beta 1.5.1)

Hello,
I was trying to downgrade my phone from the beta to Android 12 and it's now stuck in Fastboot mode. Won't let me enter recovery. Tries to boot but just stays on the nothing logo. My bootloader is unlocked. I'm assuming I need the same firmware I was running to reload onto the phone. Any other files needed?
Thank you so much! cheers

I can't enter recovery mode. Only fastboot.
Flash boot and vendor_boot and you'll be right back in recovery
If it's not booting try set active slot to either a or B and flash the images mentioned above

I'm having a similar issue coming off a fastboot stuck device. I guess I managed to delete the recovery mode from slot B so I can't get into fastbootd to flash some of the lower level partitions to make my fingerprint sensor work.
The vendor_image is the recovery?
Did you guys find any solution? I am stuck with my phone stuck in the bootloader mode and I can't seem to do anything.
Here's what I did:
1) Unlocked bootloader while being on NOS 1.5.1 Beta. Successfuly did it.
2) Restarted my phone to bootloader mode and flashed dtbo, boot and vendor_boot from SuperiorOS 11th Feb build.
3) Proceeded to restart to recovery as mentioned in the instructions but instead of restarting to recovery, it restarted to bootloader.
4) Stuck in bootloader mode ever since!
Nothing seems to be working. I have tried literally everything but cannot get past the bootloader. Please help. I don't have any secondary device to use.
