I accidentally deleted some system files ( I was on adb connection) .

And lock screen stopped working right after.

The issue is that, I have a lock pin/pattern/password, but system says, it's not correct password. I changed my password with removing password files from system, and set a new password. But the error was same, incorrect password. I tried to flash ROM, but it didn't help.After flashing ROM , abd and TWRP broke too, because of the password issue. Also I can't add custom ssl certificates, because the password problem .

Samsung Galaxy s7, Android 9 with Hyper ROM (Galaxy Note port).

What should I do to repair my system files?

  • Did you try a dirty flash?, or if you know which files you deleted on hyper rom you can try to extract them from the flashable zip and replace them. – lucki1000 Jun 29 at 12:56
