When I tried to flash xiaomi.eu_AURORA_OS1.0.11.0.UNACNXM_14 on mu ultra 14 , I keep getting the error "cannot found file flash _all_lock.bat" . I've tried this multiple times but keep getting this error every time. I also tried installing it using the updater but was not successful . I'm a tyro in this area not not very tech- saavy . Can you please advice ?
