I have an N3200 that I hacked on a full debian ARM system and pretty much ran it as my server/firewall/router etc. Part of the process meant reshuffling the mtd around a bit and updating uboot etc etc. Lots of fun and it allowed me the full package management of a debian based system.
However I'm wanting to sell it and need to put back on the original firmware. As I'm quite comfortable in uboot, embedded linux in general and the quote decryption quote used I thought it would be easy, but I've discovered that there are a bunch of files that are not available in the firmware files.
Namely, they are located in /app which is symlinked to /etc (mounted from /dev/mtdblock3). When you reset your device to factory defaults, it basically untars /img/bin/default.tar.gz over your etc and opt dirs, but that only provides some config files. All the scripts are not provided and I can't for the life of me find them in any firmwares.
So.... big favour. Can someone with an N3200 just tar up their /etc dir (minus passwd/shadow/samba and anything else that may have secret stuff in), and send it to me.
I've got everything else back to defaults (old uboot, original ramdisk, original kernel, orginal mtd structures), just not the original /etc. Can't believe I lost my backup but I originally did it such a long time ago.
