Anyone have a different partition layout, or know what the reserved partition is used for and where the data comes from?

what command did you run to show the partition table? cat /proc/mtd is empty, however cat /proc/ntd returns the following on my nexbox A3 (same as A1):

root@NEXBOX_A3:/ # cat proc/ntd
dev: size erasesize name
inand01: 400000 80000 "bootloader"
inand02: 4000000 80000 "reserved"
inand03: 20000000 80000 "cache"
inand04: 800000 80000 "env"
inand05: 2000000 80000 "logo"
inand06: 2000000 80000 "recovery"
inand07: 800000 80000 "rsv"
inand08: 800000 80000 "tee"
inand09: 2000000 80000 "crypt"
inand10: 2000000 80000 "misc"
inand11: 20000000 80000 "instaboot"
inand12: 2000000 80000 "boot"
inand13: 40000000 80000 "system"
inand14: 30c200000 80000 "data"

Also I haven't managed to get adb running on the box to download the rom image while in recovery mode, did you dump your using this method or something else?

The following should help:

cat /proc/partitions
ls -l /dev/block/platform/d0074000.emmc/by-num

adb connect ipaddr:5555
adb shell

I dumped while running in regular mode, haven't tried getting into recovery yet.

Thanks calc, that worked well; for reference here is the output of the two commands:

I also managed to connect to adb using wifi, I didn't know I could do this just by using wifi, thank you very much!

Sorry for hijacking the thread: I managed to dump the system partition to sdcard, I suppose i should be able to mount it on linux as an ext4 image; if I add and remove files will i then be able to push it back to the box (again using dd)?

Thanks

You could just individually push the files themselves over if you want. If you try to push the whole fs over you probably will need to be in recovery with /system not mounted. I haven't tried to do that before.

Hi how did you manage to dump the above? I have the same like you but I would like to dump "data" which is mmcblk0p13 (which is mmcblk0p14 in yours)?
I am using AirDroid and Terminal app so don't need adb etc. Which commands did you execute to dump stuff?
