I am trying to solve a boot loop problem on YesTel x7 running on Android 9. I did factory reset but that didn't help it is still stuck. I want to flash the system as a last resort. I have never done it before. Following tutorials I installed SP Flash Tool Download and mediatek-preloader-usb-vcom-drivers I was trying to find firmaware for that model, but couldn't find any apk file.

Does the flush have to be done with corresponding to the model apk file or can it be done with some sort of universal apk?
