heres what i have so far
Code: 
mmcblkop1 ???
mmcblkop2 ???
mmcblkop3 ???
mmcblkop4 ???
mmcblkop5 ???
mmcblkop6 amms
mmcblkop7 ???
mmcblkop8 boot
mmcblkop9 ???
mmcblkop10 ???
mmcblkop11 ???
mmcblkop12 oemsbl (?)
mmcblkop13 ???
mmcblkop14 efs
mmcblkop15 recovery
mmocblkop16 ???
mmocblkop17 system
mmocblkop18 cache
mmocblkop19 data
mmocblkop20 carrier
mmocblkop21 ???
mmocblkop22 ???
mmocblkop23 (blank. Nothing shown in hex editor)
mmcblk1p1 extsdcard
mmcblk1p2 sdext1
im pulling the other partitions to try and figure it out now

If we can figure this out, we can make a full back-2-stock/stock-rooted 'restore' for Odin


Here are the outputs from terminal

I notice this when looking inside of our official JB OTA

Code: 
assert(write_backup_amssmodem("/dev/block/mmcblk0p6", "/dev/block/mmcblk0p22"));
apply_patch("EMMC:/dev/block/mmcblk0p6:13725952:abead08dc14696a8988972f2293b92ff0edd5420:13734144:2fd67195566b4b1b118d93eca2baaf624680292d",
            "-", 2fd67195566b4b1b118d93eca2baaf624680292d, 13734144,
            abead08dc14696a8988972f2293b92ff0edd5420, package_extract_file("patch/amss.mbn.p"));
set_progress(0.025028);
assert(erase_backup_amss("/dev/block/mmcblk0p22"));

Am I correct in thinking that mmcblk0p6 would be our modem?

Also - Official guide now eh? Good stuff :smokingsomb:

Click to expand...

Yes. That would suggest that 0p6 is amms, it also suggests 0p22 is temp storage of some sort. Since it writtes to it as a backup prior to applying the patch


And yes. I was promoted to guide just today. Thx
 
Anyone handy with a hex editor? I am able to view the partitions, just not sure what to make of them :confused:

And I've tried googling for a guide/explanation and haven't come across anything.
 
Since your working on this, I think this the right time to bring this up and see if you can get this working for our device
It's for the SGS2 & S3, but running CM10, it remaps the extsdcard as sdcard I believe, hopefully it will work
