[Q] Cannot backup IMEI etc with EFS Professional with 4.3
ok so after unrooting and going back to stock to upgrade SGH-I337M to official android 4.3 I cannot get EFS Professional 2.0.70 release to work. I've rooted with cf autoroot and installed busybox. I then tried using adbd insecure, still getting same error. Then installed Titanium Backup and froze 4 Knox related apps/services, still getting this error. Anyone else?
If EFS Professional doesn't end up working, should I create a dump file of the root efs partition? I managed to figure out it's /dev/block/mmcblk0p10 but am not sure the file type/extension to use if dumping w/ adb.
Is it something as simple as EFS Pro needing to be updated to newer version? Why am I getting this error??
Thanks in advance...
