the problem is, i am not the one, who is an Android specialist, so i don't know, whether any private data from me are stored in the recovery image.
On the other hand, i don't know, whether it is working on any s6312 firmware / software release. I have made it for S6312 german version XXAMBG
in two versions, one tar.md5-file to be installed via odin and one zip-file to be installed with the "buggy" CWM recovery here, where we all have problems with.
I will check it further and when i am sure, that there is no private data in it, i will upload it here.
