Revert back from Wheezy to original firmware on Pro RNDP6000

Recently I bought a ReadyNAS Pro RNDP6000 v1. Because I was unsatisfied with the possibilities of Debian 4, I migrated to Debian Wheezy.

I did this fully aware of breaking the warranty. Using a converter to get a VGA output from the motherboard, I installed Debian 7 using a USB stick. I also upgraded the CPU to an old quad core (Q6600) i still had from an old computer. The Debian installation works just fine and I didn't even lose my RAID setup (which I noticed, does get reset when resetting/reinstalling with the original firmware).

All seemed to work just fine, until I recently discovered I was getting a lot of sky2 network driver errors in my kernel logs:

[Thu Oct 17 20:32:51 2013] sky2 0000:02:00.0: eth1: rx error, status 0x7ffc0001 length 812 [Thu Oct 17 20:32:56 2013] net_ratelimit: 85 callbacks suppressed [Thu Oct 17 20:32:56 2013] sky2 0000:02:00.0: error interrupt status=0x40000008 [Thu Oct 17 20:32:56 2013] sky2 0000:02:00.0: error interrupt status=0x8 [Thu Oct 17 20:32:56 2013] sky2 0000:02:00.0: error interrupt status=0x40000008 [Thu Oct 17 20:32:56 2013] sky2 0000:02:00.0: error interrupt status=0x8 [Thu Oct 17 20:32:56 2013] sky2 0000:02:00.0: eth1: rx error, status 0x7ffc0001 length 868 [Thu Oct 17 20:32:56 2013] sky2 0000:02:00.0: eth1: rx error, status 0x7ffc0001 length 556 [Thu Oct 17 20:32:56 2013] sky2 0000:02:00.0: eth1: rx error, status 0x7ffc0001 length 940 [Thu Oct 17 20:32:56 2013] sky2 0000:02:00.0: eth1: rx error, status 0x7ffc0001 length 620 [Thu Oct 17 20:32:56 2013] sky2 0000:02:00.0: eth1: rx error, status 0x7ffc0001 length 1132 [Thu Oct 17 20:32:56 2013] sky2 0000:02:00.0: eth1: rx error, status 0x7ffc0001 length 300

This caused the network speeds to become unstable. I would like to return to the original firmware, but unfortunately I had too much confidence in myself to backups of the original firmware and boot partition.

I don't believe the downloadable firmware helps me with this problem: First of all, it's encoded in an image and don't know how to extract it. This firmware would probably contain the content of /dev/md0, the Debian part. I however also need the content of /dev/sde1, the /boot mount of this NAS.

Basically, I was too stupid to prepare myself for this and create backups forehand. Is there any way I can revert back to the original software state of this device? I have direct VGA/keyboard access to the NAS, but I would like a image of the /dev/md0 and /dev/sde1 partitions from someone else with this device, preferably created using the tool dd. I don't know if this is legal (of course, I can prove I own this NAS, so perhaps sending it to me in a private message would be legal), but either way, any suggestions are welcome!
