[gd9719]

Hello ,i have a problem whit my a5 2017
I have updated my phone to latest version of oreo , before doing this i disabled oem unlock but i got twpr installed in my phone .
Now after the oreo update the phone is a brick , i have no command screen and if i try to enter recovery i have this message :
#fail to open recovery_(cause no such file or directory)#
Now i am on the latest version of bootloader , oem locked and frp lock active whit an infinite bootlop.
I tried to extract recovery file of latest oreo update whit cmd l4z command , success , i flashed it but still no recovery
If i try to flash twpr i get an error : custom binary locked by frp lock on download mode screen
Adb does not recognize my phone i can't unlock oem from adb
I tried to install stock firmwares a lot of times but the problem still persist
What can i do?

I finally booted up my phone and unlocked oem
but network is not working , everytime i update my firmware recovery is missing and i have to install recovery manually (only twpr work , stock recovery not working cause of bootloader)
i have tried to unpack recovery from lz4 stoc files ( latest update) create a tar whit 7 zip and flash it , flash success but still no recovery.
after erasing screen after update i have no command whit failed to load recovery no such file or directory
