Android Nougat AQDG
Flashed TWRP but it booted to phone, then locks up at boot screen. This is usually dm-verity at work. Flashed stock firmware but phone still won't boot to recovery, verity appears to kick in immediately upon first boot.
How to get past this?

I rooted and changed kernel on my P9 lite single sim in order to use OTG, but then went back to full stock for OTA update.
Phone downloaded it but when it reboot to install, instead of booting recovery mode started a boot screen loop.
At this point, I can just let it go out of battery and then reboot in normal mode.
FASTBOOT DOESN'T WORK, as well. Both fastboot and recovery mode are broken. Both came up in a boot screen loop.
How can I solve this?
Thx.
The problem is, if I try to update with OTA, that the phone enter in a boot screen loop. Until the battery is down.
No recovery, nor bootloader.
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?)
Here's what happened:
1. flashed wrong twrp version for 8.1 oreo, used correct CF-auto root
- tablet booted to stock recovery screen a few times but i figured it was part of the process so I just rebooted
-ended up getting a failed identification verification
-i know the auto root worked because my warranty is void :silly:
2. reset my tablet from the failed verification screen
-eventually got myself to a blue erasing screen loop
-flashed twrp again and got myself to a point where booting into recovery resulted in glitchy lines
3. attempted to factory reset from reboot with adp
-not sure if it worked tbh
-also tried to reboot to recovery screen and that didn't really do anything
4. found and installed the proper version of twrp (3.2.3-4)
-now stuck in feedback loop that occasionally shows the twerp screen so i know something's right
-won't boot to recovery screen but will boot to download page
-doesn't show up in adp devices during this loop
-- have CONTINUOUSLY tried flashing firmware (I've tried 6.0, 7.0?, and 8.1) none of them have worked, sporting some variant of secure check fail (PIT, bootloader, or RADIO)
-- have tried the mod here but it fails after param.bin and i can't use it directly after auto root without rebooting because it gets stuck on setup connection
-- most likely not a hardware problem because i had this tablet for basically a day before i did this to myself
--OEM is unlocked, not that i could change it even if it wasn't
---is there anything that anyone would recommend trying before i take this to geek squad (who may not help me but i'm still going to try) or should i just cry myself to sleep over wasting $300 :crying::crying:

Flash twrp, FORMAT (not wipe) data, install Magisk.
Reboot.

What's stopping you boot to Download mode?

I can boot to download mode but i can't boot to recovery mode after flashing twrp. When I try I just get stuck in a reboot loop, so I can't try to boot to recovery from adp either.

If you can flash twrp then not booting to twrp must be pilot error.
It MUST be done immediately after flashing in odin.
I got my Mi A1 today and it came with Android 7 installed, so I decided to install LOS. I unlocked the bootloader and then I booted into TWRP using fastboot (I didn't flash it), it gave that "system is read-only" warning. I tried to reboot to system without doing anything and it was stuck in a boot loop. Then I booted into TWRP again and flashed LOS sucessfully. When I tried to flash gapps, however, it failed claiming I was still running Android 7. I rebooted and it booted sucessfully into LOS, but that was the last time the phone ever booted. Now it shows the unlocked bootloader message and then gets stuck in a blinking black screen. I can't even boot into recovery or fastboot anymore.

It seems you will have to flash stock ROM using Mi Flash (no idea how to use it so search it) and, once is done, flash LOS again.

I somehow managed to get to fastboot and then I used MiFlash to flash the stock rom. I'm back to the bootloop, which is an improvement, because at least I can consistently get into recovery and fastboot.
The phone got stuck in that black screen after I tried to flash LOS, should I actually do it again?
EDIT: I flashed the stock rom a second time and it's working again. I don't know why, but I'll take it.

Update to stock Pie before trying to reinstall LOS again. Hope this time works.

You should install 1.0.8.0firmware first before install 9 ROM!?
I do have a decrypted OP5 and I did try to flash both the latest OOS stable & the latest OB and to run it unrooted.
After wiping everything but the internal storage and flashing latest OOS, I did flash the "No Verity" and did reboot the device.
It shows the unlocked bootloader warning, the first Android boot screen and right after that, when it normally would go to the boot animation screen, it kinda rapidly restarts, gets back to the unlocked bootloader message and after that it boots back into TWRP.
The outcome is always the same, unless I flash magisk after the No Verity. Doing so it boots into the OS with no problems whatsoever.
Does it has something to do with the decryption or what should I do in order to run it without root of I want to?
