I blocked access to download the ROM1 backup because I didn't want us all to have the same serial number. But those who already downloaded can try to write ROM1 using what I wrote above. You can also wait for the release of the Chinese firmware or custom firmware. The way I described works. Only need to select the format + download. I did more, I just formatted everything and managed to restore from backup without 0xC002000C error. Although the risk is probably present - be careful!
One more thing I used is the Preloader taken out of ROM0 but the one in the official firmware should work too. If it does not work, I will post my preloader
