Hello XDA Members.

I require your valued assistance restoring my Lenovo TAB S8-50LC.

The issue began after installing xposed framework. It sent the android in to bootloop. I tried to restore it to factory state using recovery. After seemingly installing the factory mode, it froze on lenovo logo screen. I attempted to restore to factory mode several times with the same results.

Then, I decided to flash stock rom from this thread using Intel Flash Tool. It loaded to 79% and failed.

I tried to boot in to bootloader again but I get this message

Boot Failed. EFI HARD DRIVE

I can only boot to fastboot and every time I try something, I get this error.

FAILED <remote: unknown command>

So, the current state of my android is, I can only boot to fastboot, I can connect it with my pc and receive device when i type fastboot devices (adb device doesn't display anything) with the restriction unknown command.

Is it time to bury my tab or is there hope for him yet?
