Hey guys.

I am currently working on making my app "kTool" compatible with the SGS3 (see here and here), for the intl. version I9300 it already works fine, but there seem to be quite some differences on the i747....

I am missing some details on partitions used on the i747.
I already found the EFS partition (mmcblk0p11), but I'm missing the partitions for kernel, recovery, modem FW and PARAM block.
If anyone know those, please do tell

And/Or I could really use the output of the following two commands on a terminal/shell:
Code:
su
ls -al /dev/block/platform/dw_mmc/by-name 

ls -al /efs
Thanks

Some folks on the Sprint side posted some info as well, and yes, there seem to be several differences compared to the international version.

Thank you!

I am slowly gathering all required information to make it work on those models.

Another thing that confuses me is the lack of "nv_data.bin" in the /efs folder.... So the standing question is: Is backing up that folder and dumping the partition it's mounted from really enough? Or would other locations needed to be backed up as well to have the IMEI saved?

You may want to get together with zeesubalpha, he's working with IMEI stuff in this thread.

Thank you for your work on this.

Yah, but in the wrong direction - backing up the EFS partition seems no longer to be the way to back up that sensitive data holding the IMEI and stuff: http://forum.xda-developers.com/show...4&postcount=51
