hi
i upgraded my phone to nougat and used few days after that i decided to go back mm. i put mm update.zip and upgrade with recovery (volume up + power). when i try to boot asking me passcode but doesnt accept my passcode and doesnt recognise my fingerprint. and few seconds after reboot itselfs. when i try to clear data still asks me passcode. my pc doesnt see my phone in recovery or fastboot mode.
what should i do?
