hello
i have just fixed the same problem. vtu00m emmc with rev 0xC, did not know the revision before i hit vtu00m repair, ended up with 0000 name, then i wrote 2 extcsd backups that i had from previous phones. one by one. dont really know what was the revision of the emmc that i had backedup earlier, but, anyway, one of them i guess worked. name remained 0000, but set entered download mode and i was able to service it. if you guys need those files, tell me
best regards.
