Sorry for posting in old thread,
can i do it like here with the samsung galaxy s3? SGH-I9300 (not the LTE version)
second question, i have a backup file like this : efs_01Oct2012-1028.tar.gz
its only 35kb
but inside is the file: efs_01Oct2012-1028.tar and size ~5mb
inside that is the efs folder with the files
unzip the .gz file and flash?
sorry for my english!!
thx for helping!
