Single 1.64 GB RAR archive with scatter firmware for model A107F, binary U8, build A107FXXS8BUC1, on the MediaTek MT6765 platform and Android 10. Being one file, it needs no companion volumes. The scatter file inside is loaded into SP Flash Tool or a similar MediaTek utility to rewrite the partition set, which is the usual route for unbricking an MT6765 handset. Make sure the device runs binary U8 or lower and save NVRAM beforehand so IMEI and radio calibration remain intact.
