Hey! I found a little bit of time to try it out! Thank you very much for trying to help me! When I trying to boot it up I getting:

fastboot boot tecno-ki7_boot_adb.img
Sending 'boot.img' (26862 KB)                      OKAY [  0.655s]
Booting                                            FAILED (Status read failed (No such device))
fastboot: error: Command failed

and logs from dmesg: https://0bin.ch/?51a49ed0a5778a18#DPxaTLsafGXC2jEokDCF5mZ2YiexKJHoYkz7GCthwMNa Also adb devices and adb shell does nothing.

I can wait :) Thank you a lot

tries to boot android, fails and goes to recovery

It still won’t start

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.

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

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

I passed the test and got this result :)

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

yep

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 …

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!
