I flashed TWRP onto my dad's Tecno Spark 8C (KG5Q), but now the phone won't boot into Android; it only boots into TWRP. The biggest problem is that the touchscreen isn't working, so I can't do anything. I tried using an OTG cable with a mouse, but it didn't work.
I realized i can access adb in twrp for a few seconds an i succeed boot into bootloader and flashed stock boot img but instanly i think i should try different twrp img and now i can't even boot into twrp and device in bootloop. In this situation how i can boot into fastboot again? I don't know why i did that really...
Sorry for the mess in this thread. I fixed the problem using the MTK Auth Bypass Tool. I rebooted into Fastboot while it was bootlooping and flashed the stock boot image. I then relocked the bootloader. I won't mess with this phone again. I can't test GSI with the DSU Loader, and I don't know why. So, I don't want to take the risk of flashing GSIs and waiting to see if they work. Instead, I will debloat the stock ROM. If you have experience with this phone, especially with GSIs or anything similar, please reply.
