My advice for future: just try to use language for things that interest you. It doesn't matter what it is. Youtube videos, films, books, games, anything!

Honestly, no :D Actually, I write the text myself and then ask AI if I wrote it right

I can wait :) Thank you a lot

I passed the test and got this result :)

It still won't start

tries to boot android, fails and goes to recovery

I don't have root and I don't have custom recovery :)

TWRP won't load :( The phone reboots and the error appears again

Here is the exact build information from my stock recovery screen:

Device: TECNO Spark 10 Pro (TECNO/KI7-GL/TECNO-KI7) Android version: 12 (SP1A.210812.016) Build number: 230703V2369 Build tag: user/release-keys

I don't have the stock firmware package or scatter file on hand right now, but this is the exact build that is currently installed.

you can use everything, I think. Just search what you need. You can learn basics by videos, or maybe you like more books? Then just type: good books to learn ...

yep
