After a full night issue is still pending.
The OP has to make his MIFLASH application working and flash OREO rom in order to refresh the phone partition that is messed.
I gave him some directions in the first posts. I am not sure he took care of.
No more way to try recent rom that are all under PIE.
Note: EU server is slow because of the huge download for weekly rom, but XIAOMI official for fastboot rom download is not overloaded.
Выражаю огромную благодарность!!!!! Прошился УРА!!!

Thank you very much. Can help anyone. I did everything as usual on new firmware did not work. !!
This is from the Russian forum, suitable for xiaomi.eu. It is important that Oreo be the first to stage 1102.
