mamo_mogon03 Well, lets make some clear about This. UFI support flashing, repair imei, and any special task for Mediatek for both Generic and Secure based Chips.
Mediatek Generic they need no any sign firmware, da, auth, etc, mostly MT65xx series for old ones.
Mediatek Secure need sign, special da, auth, etc, mostly MT67xx for new ones.
So, if you working with MT67xx, first you need to have their special sign da for every model to make flashing, identify, repair imei in metamode. It is not possible to include all sign da, auth, etc for MT67xx devices to UFI Box software due to amount of this brand and model that can be HUGES.
Of course, we adding for some popular device, like asus, oppo, xiaomi, vivo, huawei.
For the other, you have to collect it by yourself.
FYI Just include DA and auth file in your folder firmware, ufi will auto load it as Default Loaders. Then you can operate any task that available in the software.
