I did search and came across couple posts which I'd used; listed below.
I've read and followed these instructions from http://forum.xda-developers.com/show....php?t=2389426
As well as using the tools listed on that page.
I've also used Dr.Ketan's aroma efs backup/restore to try and restore my efs and I've tried EFS professional.
I have old efs back up from 9/10/2013 in the .img file and the other one from 24/08/2013 in tar.gz file.
Is there any other way to try and restore my phone to its formal functional glory using any of these back ups?
Any help is much appreciated.
