Can anyone help me understand the issues with IMEI and EFS. Specifically, what should I have a backup of? I've successfully made a backup with QPST (note: avoid ROM's that don't include the standard dialer or a broken keyboard, or blame tyler), and due to problems with ROM's correctly detecting my N7105T, have even performed restores.
So does QPST backup EFS as well as IMEI? Is it all I need?
Also, I've seen references with EFS v2/3. Any pointers to more info as it applies to Note II/N7105T
