Hey community, before starting im a completly noob in things like this and i have no clue about that at all. But somehow 3 years ago i wanted to root my p20 lite and since then i always have the booting screen not trusted etc etc. So my question can i get back to the normal state just like i bought this Smartphone as a new. Just a normal Firmware or whatever pls.

You have to flash service ROM via dload mode, what is your complete build number?

- Download the ROM
- Unpack the .zip archive, open "Software" folder and copy the folder dload to the root of your SD CARD (without unpacking it!!!).
- Turn off the phone and use 'three buttons combo' .
Dload method will erase all your data!
(and lock the BL again)
Whats the three Button combo? should i go in erecovery? or in the other Menu and there is an option to install it from SD-CARD?
