Here's an output of /proc/mounts, might be help full other devs:

which one is recovery partition does anyone know?

run

ls -l /dev/block/platform/sdhci-tegra.3/by-name/

and that should show all partitions.

Thanks!

try

ls -l /dev/block/

and if you see r on the 3rd from last line of each partition, do the following commands:

adb shell cat /dev/block/platform/sdhci-tegra.3/by-name/lnx > lnxfile.bin
adb shell cat /dev/block/platform/sdhci-tegra.3/by-name/SOS > SOSfile.bin

Permission denied for cat

yep, that's what I figured but it was still worth a shot. :x

You'll need root. If you can get it before you have to surrender that tab, it'd be great.

run this one:

cat /proc/partitions

and this one:

fdisk -l /dev/block/mmcblk0

this command would be interesting too:

cat /proc/cmdline

And if the file exists execute "adb pull /proc/config.gz"(or copy it via rootexplorer) and post it here. It's the kernel-config

Cool - these are btw mostly generic tegra names, while most are probably obvious I've "translated" them below.

1. APP -> system
2. CAC -> cache
3. LNX -> boot.img
4. MDA -> Unknown
5. MSC -> Misc (bootloader commands and other misc stuff )
6. PER -> usually a fat partition containing sensor calibration etc. - per device provisioned.
7. SOS -> recovery.img
8. UDA -> /data - "user data area"
9. USP -> Staging

There's no standard "dos" partition anywhere, so that won't work.

At least cmdline is actually protected from normal users in newer kernels and same with config.gz I believe. Worth a shot though. (FWIW, usually tegra bootloader fills in kernel cmdline rather than hardcoding it in boot.img )
