Official OS

[LExor456]

Hello.
I have to send my MI10 back to the after-sales service for a screen change.
It is still guaranteed, but I installed a eu ROM.
Do you know how I could reset it with the official stock OS, and the official stock twrp?
I wouldn't want the ROM mod to void the warranty because my phone wouldn't be supported for free.
Thanks

Use official flash tool to write official firmware.
That will flash the recovery too, so the TWRP will be replaced with the stock recovery.
Check the official page for the instructions and the softwares, you will need to browse from a PC that page: https://new.c.mi.com/global/miuidownload/detail/guide/1
Follow the instructions for "Fastboot Update", at the step 2 you have to choose your stock firmware.
