FRP lock (factory reset protection lock)
The main issue facing on roll backing is frp issue
FRP lock is one which forces device to check for update and stuck on it on startup
We can ensure that the device is in frp lock by viewing a lock symbol on statusbar(check attachment)
This happends because you are used roll back without removing your google account from settings
FRP erase is possible through ostla but it may cause brick on some device
So we have to go for another way
Instructions-
-Flash oreo using ostla (skip if you are in oreo)
-Reset device
-Update device to pie (recommend to flash 339B firmware)
-Add your google account
-Untick the backup to drive option on your first boot setup
-Remove your google account
-Reset
Go for the rom or gsi you want:laugh:

Poored thru several forums and sources found several types of solution's such as KIES, Smart Switch, Odin (back2Stock), i have attempted all of these the Boot logo with frp lock on is now off i can now boot to the rom.

While in Android, enable developer mode, and find the Enable OEM Unlock item. Turn it on; this disables the Factory Reset Protection and should let you flash a custom recovery in Odin.
Hey Guys,
I really really need your help. At first I give you as much information as possible, even if it may be unnecessary.
I was as OOS 4.1.3 with SuperSU 2.79 rooted and TWRP 3.1.1-0. My Phone is secured via fingerprint and unlock pattern as backup (if fingerprint fails)
Few minutes ago I Wanted to update to OOS 4.1.6 with root via SuperSU 2.82 - it was successfully updated - but I accidentally wiped data partition (not my userdata) - so that I had to reconfigure my phone completely. Because this would take hours to do so, I decided to restore my backup that I gladly created just before the update. The Restoring process was also successful, but now after restart, my phone doesn't accept my unlock pattern! - As always after a restart, I need to use my fingerprint AND my pattern to unlock and use the phone - the fingerprint is still recognized, but the unlock pattern is NOT!
So my Question is clear - HOW do I enter my phone? - behind the pattern issue it's working, it's even connected to network and I can receive calls, use the camera, but nothing else without unlocking because it always says that my pattern is wrong.
So is there any possibility (maybe via adb or similar) to unlock my phone or do I really have to set up my phone from scratch?!
Edit: Thank you soo much 93drago, your link provided the answer I needed
That's a bug with TWRP backup - here is detailed instruction for how to solve it. In short - you'll have to delete few files in TWRP file manager.
Frp unlock is simple. Boot to recovery, select safe mode. When in safe mode turn off device administrators, wipe any Huawei account and all others, enable Dev mode, then ADB, make pattern unlock, force close Google account manager and clear cache, data, same for Google play services, reset phone from settings, that should do it. I did it with latest firmware and updates also on the P-smart 2019 and p8 lite.
Hello, I had problems with my Sony Xperia XZ2, in past it didn't boot up, stuck on logo with Sony, I flashed a firmware with flash tool and after that it boot up, it worked but now, after 1 week it won't to unlock the screen with my password, after I enter my password ( it is a model password ) some theme or app crash I think and shows "com.sonymobile.runtimeskinning.common,,," and just ask again and again the password .
What can I do to do not lose data from it, it is very important for me ?
I tried to erase cache from fastboot but bootloader is locked and I can't.
Can I flash firmware in some way and repair this bug ?
I tried to perform the boot root, without first releasing the option to release this option (Development Menu). Now I am without the option to unlock the initialization and without being able to perform the boot. When trying to run fastboot to restore the factory version, the following errors appear (attached image).
Has some mode to remove this state, to try to execute restore: 'Erase is not allowed in Lock State'
Since the bootloader is locked, you cannot root or install a Twrp. Tried to delete your data(wipe data) from recovery or Miassistant or use this tool (not 100% guaranteed).
