[LG Nitro HD] schwin97:
Found some interesting information while playing around with adb shell and subsequently su'ing on my phone. I attempted to 'cat /proc/mtd' in order to determine which partition on the phone is boot and recovery, but /proc/mtd doesn't exist on our devices so that didn't work. I was able to cat /proc/mounts which led to:

cat /proc/mounts

That is great so that you know what partitions we have, but which one do I need? As I was looking through the directories on my phone noticed the directory /cache/recovery and within it a file called 'last_log'. When I looked within this file I hopefully hit the motherload:

# cat last_log
cat last_log
Starting recovery on Thu Jan 1 00:10:23 1970
framebuffer: fd 4 (720 x 1280)
recovery filesystem table
=========================
0 /tmp ramdisk (null) (null)
1 /boot emmc /dev/block/mmcblk0p8 (null)
2 /cache ext4 /dev/block/mmcblk0p28 (null)
3 /data ext4 /dev/block/mmcblk0p30 (null)
4 /misc emmc /dev/block/mmcblk0p25 (null)
5 /recovery emmc /dev/block/mmcblk0p13 (null)
6 /sdcard vfat /dev/block/mmcblk1p1 /dev/block/mmcblk1
7 /system ext4 /dev/block/mmcblk0p27 (null)

I:Got arguments from /cache/recovery/command
Command: "/sbin/recovery" "--wipe_data"

So I have created images of both boot and recovery, and now I will see if I can deconstruct these down to the actual filesystems...?

If anyone has any ideas for what the next steps are, please let me know... I am just bumbling my way through - hopefully in the right direction, and without a bricked phone in my future.

Thanks!
