any help thx

first when you want to remove mi account in QUALCOMM CPU you have to write only persist patriation from original latest firmware, if you erase persist partition, it may trouble, now u can take security backup then after universal factory reset write latest firmware( load from xiaomi firmware updater website), after that write backup, post result.
