maybe only possible to revive it using loader + oeminfo solution, this would bring it to fastboot screen i suppose, maybe then could reflash it with original full stock rom.

I am also facing the same problem

If the device is still visible in the device manager then standard flashing solutions to attempt repair should help.

I found what you need is another mod apk, I also got flash error 1 time and after running the program again, it's very good
