I want to update my EU rom without losing my internal storage data. Currently I am in miui.eu.12.0.3 and I wanna update to miui.eu.12.1.1.0
Is it any way to do it.
It's very simple: Download the new ROM and install it in TWRP then wipe Dalvik/Cache after installation is finished. Reboot and wait 10~15 minutes for the first boot (after the installation of the ROM's update) and voilà! ^^
