Sorry @KamakuTiu I can only provide you a good link in spanish, not sure if you can work with it (from your nick I think you can be from Catalunya in a strange way...)

There is no pain, you just have to follow a good tutorial, and your Mipad 4 plus will be in Miui 10, in your language, with google and with OTA!
The only bad new is that you'll have to wait a mounth to unlock your bootloader
Hi! Anyone knows how to update Mipad to the last versiones of xiaomi.eu? There is Mocha Rom, but always call for TWRP recovery, and I cannot find something different to CWM recovery in the list for my MOCHA Mipad.
Sorry if someone answered this cuestión before...
Editado: no problem, yesterday...
