I haven't slept since two days trying to fix this thing , I have a VIVO Y15S (MTK6580) . I planned to root it 2 days ago but that required me to unlock the bootloader so i went into fastboot mode to unlock it . Im a noobie with MTK Devices! Tho!. Everything went well! a dialog box showed upo saying all the data will be wiped if i unlock my bootloader i chose ok then it rebooted to recovery mode wiping cache but when it was wiping the data it failed i restarted my phone and the same problem again, it brought to the verge of even flashing it but nope still not working out! It just wont work normally like it did before without wiping data!! Help me!
