Please Help my Tecno G9 Pad is not booting after i flashed gionee EBR files. I deleted cache and wipe data to factory reset but it failed. I re flashed back the original EBR but it still cannot boot. it just stuck at the logo and it can go to recovery mode. I already copied the backup with mtkdroid. so I Flashed the whole files but still cannot boot. i don't know what to do
