Prequisites
Phone Rooted
Smart Phone Flash Tool Backup - Specifically protect_f file (for a Dual SIM phone, maybe different for a single SIM phone)
Linux OS - I used Ubuntu in a virtual machine
Android SDK platform tools for ADB access
From a terminal (CTRL + ALT + T)
At this point copy the file "protect_f" in the ~/protect_f
then continue:
Enter your password
then continue:
Copy the files in the f/md folder to a folder on your phone and using a file manager with root access copy the two files into the /protect_f folder or any toher means
NOTE: You will probably get back your cell access immediately. However, please continue to make the permissions and ownership are the same as the original.
Also if you have a dual SIM, one of the files from the protect_f folder will automatically be created in the protect_s folder
To clean up the files on the Linux OS:
To change permissions and ownership on the files
From an adb shell for your phone:
Take note of the ownership of the md folder, on the phone I used they were ccci & nvram, in Linux the ownership was 9996 & 9997.
At this point I put the phone in airplane mode, just as a precaution to make sure the rest went smoothly
If you have a DUAL SIM phone, for the second folder....
You can now take the phone off of airplane mode and reboot your phone to be sure it is working,
ALL DONE!
