I have at me Huawei P30 that need to change LCD - totally damaged. The phone is at 9.x.x.xxx EMUI and need to get a 02352NLL [It's black] Like part number for and LCD.

Currently Huawei do not deliver 02352NLL anymore, so it's replaced by 02354HLT. The last one service pack need 11.0.0.xxx Like version to be working.

Tested

So - i have at me phone with 11.x.x.xxx and read it out:

Cannot write a readout from 11.x.x.xxx to a old FW board?

What can be wrong?

P.S. I wasn't found a factory upgrade UPDATE.APP for a 11.x.x.xxx

Any hint is welcome.
