I'm looking for how to get EMUI 9 right now. I saw a method on XDA (https://forum.xda-developers.com/huawei-p20-pro/how-to/guide-how-to-update-to-emui-9-c432-l09-t3883557)
Now my question is, if I will keep my guarantee and if that is certain?
This is such a file that you then with an OTG adapter installed (without root, no open boot loader needed).
OTG adapter, because Huawei has no SD card slot.
Problem solved, because you keep your guarantee. ✔
