New here, some doubts on 4A


Jun 20, 2019
Well, hello there! I'm new here and with flashing Xiaomi's. I read a guide to unlock bootloader and I want to know if I must backup everything because once I unlock bootloader I lost all date (factory reset).

Also another thing about TWRP. In their webpage says that "This device uses dm-verity! This means that swiping to allow system modifications will prevent you from being able to boot if you are using the stock kernel. In order to bypass dm-verity's boot prevention, you will have to install a kernel that has dm-verity disabled in the fstab." I've never read that. This no other chance that change the stock kernel to flash another rom?

I have MIUI 8.5.1 global stable, never get update to 9 or 10, don't know why. The Xiaomi.EU MIUI 10 for Redmi 4A, what does it brings? it's convenient? is there improvements over MIUI 8?
