you should try something like this...

dw_mmc might have a different name
ls -al /dev/block/platform/dw_mmc/by-name

just run
"ls -al /dev/block/platform/sdhci-tegra.2/by-name"

"ls -al /dev/block/platform/tegra.3/by-name"

one of them should list if they have names defined... if not as an alternative look into fstab in root... should have basic cache/data/system

these are the ones I know.... you have to figure it out what they are... I didnt mess much with the bootloader....

APP system
CAC cache
UDA data
MSC misc
LNX boot
SOS recovery
USP staging

my suggestion is dump recovery partition .... unpack it and look into recovery fstab

So i finally decompiled everything to get to the recovery.fstab. The only partitions I've never seen are the pac and the MDA (metadata). I'm getting closer to getting this recovery done. Is there a good walk through or tutorial for creating your custom twrp recovery? Thanks

Well any additional information would be helpful. i was able to decompile the blob to blob.bct, but im stuck at this point. Right now the blob.bct is in a binary format. Need to be able to convert it to viewable txt and dont know how to do so. Also need the boardconfig.mk and need to figure out how to pull this info. Thanks again for assistance.
