I am trying to restore an S20fe g780f to stock firmware.
You are try to flash firmware lower than what is on your phone (you cannot downgrade firmware ).
Device ? = current bootloader ( needs this versiom or higher ).
Bimary ? = bootloader trying to flash.
Download latest firmware from website or ues frija pc app.
Bootloader version number can be found on download mode. Should be a line saying:
AP SWREV: B:? K:? S:?
B? = Bootloader version number.
