Hi Guys, I bought a second hand 10 Ultra that had the EU ROM version 12.10. Battery life, everything was perfect. EXCEPT the camera! And the camera was THE only reason to buy this phone. Horrible photos, a lot of smear and haze when a light source was in the picture, like a light bulb, computer screen, almost unusable. So after reading that the chinese ROM can fix the issue I've used Xiomiflash and installed the latest official CN ROM : https://xiaomirom.com/en/download/mi-10-ultra-cas-weekly-V13.0.0.1.1.DEV/ . Fantastic photos, great camera overall but many bugs concerning all the apps installed via Google Play. no real time notifications, gmail interface very laggy , an important battery drain (10% overnight as with EU Rom was 1-2%).
So I have decided to go back. I have download and tried to install an EU ROM, it installed something but froze halfway and after a few hours I stopped the program.
Tried again and no luck, now I get the error message "anti rollback check error". I have google it, ran the cmd I have a code 1 in the phone.
On youtube there is a fix to that and all the comments are positive, so I opened the "bat" file in a txt editor and deleted the first lines about the rollback check.
Open the EU ROM with Xiaomiflash and It started to work but froze again after 10'-20' for hours.
So for the time being I think I have a bricked phone that starts with a bootloop, I can get in into the chinese recovery but using that it gets it again in the bootloop, I tbelieve that it"s booting into a corrupted ROM.
I have found this tool from XIAOMI http://zhushou.xiaomi.com/ but it's all in chinese, I have tried with a camera translator app on another phone but it's just impossible to translate.
I really really hope I can still get it back to work! Ideally with an EU rom, a 12.5 version, if downgrading it's impossible then again with the version13 beta CN ROM that worked.
Anyone any idea?
To resume evrything: Phone worked with EU ROM 12.5 - Used xiomiflash - wipe evrything- installed CN rom v13 - wipe evrything /tried to reinstall EU ROM v12.5- roll back error -stuck - wipe everything/tried to reinstall the same CN ROM V13- stuck halfway - Phone in bootloop/ fastboot -can access recovery mode that doesn't help.
I know it's long but I spent 2 full days and evenings trying to solve it :-(
Thank you !
