[datscoolmetoo]

finally i figured a way to fix this issue. it worked for my locked H818P, hope it helps everyone
you need root for it.

here are the steps:
1. setup adb
2. enable USB Debugging
3. connect your phone to the PC and open an adb command window

4. execute these commands

adb shell

su

dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst1

dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst2

reboot

i found this on here

How do you enter su mode. For me it is denied despite phone being rooted and running adbd app on phone to supposedly allow the su mode.
