My Tecno H7 got messed up after trying to flash a custom rom on it so i wanted to revive it by flashing the stock rom via SP Flash tools. When i load the files and connect it to PC all it does is light up the screen and keep rebooting while displaying some weird flashing colours. It also makes a 'connected sound' then disconnects again after about 3 seconds hence Flash tools cant even begin the process. Please guide me on what to do.
PS: 1. I can boot into CWM recovery normally
2: I tried to flash without a battery but got the same annoying connected then disconected problem
3: I believe i installed the necesary drivers as i followed your tutorial on that. I also installed Universal ADB Drivers but no change.
