yes, but you will use his personal data, which is not ethical

If i do it just after a factory reset there wont be my personal data in the dump files, right?

Because im planning to to reset the tablet.

Yes, factory reset erase the data block and when you dump this block with "dd" command, you dump a empty block.

Android have some blocks :

boot -> (read only without root) it have the linux kernel

recovery -> (read only) it have the recovery menu

system -> (read only without root) it have the android system

data -> (no read without root) it have apps and personal data

sdcard -> (read/write) it's the internal storage

Share with us the firmware, so we can make an update.img

How can i do that? explain it to me. is it the same thing hmsintrepide is asking for?

This command create in your internal storage a .img file. It can be take 1-3 minutes by command. Start by mtd0, mtd1, ... and when mtdX have more than 1 go don't do ... mtd7, mtd9, mtd10

 

Edit :

I found this :

• misc (mtd) mtdblock1

• kernel (mtd) mtdblock2

• boot (mtd) mtdblock3

• recovery (mtd) mtdblock4

• system (ext4) mtdblock5

i prefer doing it after the factory reset. and i think doing it myself is the simplest way. should i dump only these files above or the whole thing?

ok

You did well, you can zip the biggest file (mtd4, mtd5 and mtd7) and upload all separately in the web (dropbox, mega, ...)
