I need to make an EFS backup, never have before and flashed tonnes of roms, lol. But after reading it's probably a good idea.
Currently on CM13.
However, I've run into an issue. I downloaded Terminal Emulator. I enter "su" and it says on a new line: 255|u0_a104@oneplus3:/
So I then tried to enter: dd if=/dev/block/sdf1 of=/sdcard/modemst1.bin bs=512 - and it says permission denied?
Any help? :]
