PRA-LX1 Decrypt Screenlock Failed


Hi,

I have a unknown screenlock PRA-LX1 that came in with B191 FW. I used EFT to flash update and cust FW app files for 8.0.0.361 FW without userdata partitions. It booted to the lock screen successfully - data preserved.
I then started the decrypt screenlock function, it worked up to the 'authorize ADB' part. When the phone booted up it just displayed the 'Starting Android' screen forever, I never got past it to get the enable ADB prompt. EFT timed out waiting for the authorized ADB.
After it failed I found out I was able to swipe down the notification shade and get to settings to enable AND authorize ADB. I then powered off the phone and tried the decrypt screenlock function again - this time it failed with "could not patch data1". I removed the ADB authorization and turned off ADB and tried again, same problem.
I then reflashed the full 361 FW (again without Userdata) successfully. I tried decrypt screenlock again and it failed again "could not patch data1".
I tried flashing full 8.0.0.399 FW successfully. Still got the same failure on decrypt screenlock.
Now with 399 FW it doesn't say 'starting Android' anymore. Instead there is no lock screen, just 'slide to unlock' with open padlock, the wallpaper, the navigation bar and the notification bar. Interestingly I can navigate in settings and see things like App data storage/permissions etc - so data is still intact.

It's like the patch from the first decrypt screenlock attempt is still in place and the screenlock is temporarily removed for ADB auth - can I restore it without losing data?
