Depending which device do you have, and whether you have saved the stock MTDs or can get the MTD backup from someone.

restore the original pogoplug firmware on an e02 and the mtdblock partitions were wiped and no backup exists.
I also dont have any backups so will have to take the backed up partitions from somebody here
They have the backups here http://forum.doozan.com/read.php?8,21594 but cant download from last link , page never opens .
If you could help out here

you seem to have mtd-0 from my dropbox what else do you need?

@Gravelrash,

First verify:

fw_printenv mtdparts

expected output

mtdparts=mtdparts=orion_nand:1M(u-boot),4M(uImage),32M(rootfs),-(data)

cat /proc/mtd

expected output

dev:    size   erasesize  name
mtd0: 00100000 00020000 "u-boot"
mtd1: 00400000 00020000 "uImage"
mtd2: 02000000 00020000 "rootfs"
mtd3: 05b00000 00020000 "data"

and then nanddump:

nanddump --noecc --omitoob -f mtd0 /dev/mtd0
nanddump --noecc --omitoob -f mtd1 /dev/mtd1
nanddump --noecc --omitoob -f mtd2 /dev/mtd2
nanddump --noecc --omitoob -f mtd3 /dev/mtd3

To restore mtd1 to mtd3.

Prerequisite:

Check for bad blocks. There should be none shown from the following command:

dmesg | grep -i bad

Flash mtd1 mtd2 mtd3:

nandwrite  --noecc  /dev/mtd1 mtd1

Expected output

Writing data to block 0 at offset 0x0
Writing data to block 1 at offset 0x20000
...
Writing data to block 30 at offset 0x3c0000
Writing data to block 31 at offset 0x3e0000

nandwrite  --noecc  /dev/mtd2 mtd2

Expected output

Writing data to block 1 at offset 0x20000
...
Writing data to block 254 at offset 0x1fc0000
Writing data to block 255 at offset 0x1fe0000

nandwrite  --noecc /dev/mtd3 mtd3

I read this post. I have a Pogo E02 which does not start the cloud engine software anymore. Arch Linux is still running on this Pogoplug. I have a few questions:
- my backup of the nand only contains mtd0, mtd1 and mtd2. What is stored in mtd3 and is a restore of mtd3 neccesary?
- what is the best way to install fw_printenv, nanddump and nandwrite in Arch linux?

Not necessary.

You could run these binaries on any Linux systems, Arch, Debian, Fedora... No need to install.

But if installation is needed, use pacman.

Bodhi, thank you for your reply. I think I did something wrong: my Pogoplug does not start. Even when I connect a serial cable.

Still looking for mtd1 , mtd2 and mtd3
@Gravelrash has only mtd0 in the dropbox link
@bodhi please help

shv will upload an original mtd2. You only need mtd1 and mtd2. There is nothing on mtd3.

You have stock mdt0 from Gravelrash. And need mtd1 (kernel) and mtd2 (rootfs). If you have instaldl rescue system, it will be erased when you go back to stock. So in case you want to go back to boot rescue system, you should back up mtd0, mtd1, mtd2, before restoring stock.

The envs above indicated that you have not flashed the new u-boot env image. Do you have serial console? if you do, pls post the boot log. If you don't have serial console, post the log of what you did during installing new u-boot.

mtd2 (rootfs). I could upload mtd1 if shv does not. The kernel mtd1 is pretty generic.

Something fxxked up in updating , both rescue and rootfs are booting fine as i can check from LEDs but lost access to them using IPs .
Have serial will check output

earlier boot env was correctly installed , boot booted fine and then even rootfs booted . Accessed both using putty
restarted then lost access to them in rescue and debian

I uploaded the mtd1 image of Seagate Goflex Net: Link. The mtd2 image of Seagate Goflex Net can be downloaded from this Link.

@bodhi,
I had to use the flash command without --noecc option to restore mtd2.

nandwrite /dev/mtd2 mtd2

I am not sure if Goflex Net mtd2 will work on Pogoplug E02. The boot environment has one additional variable.

ceserialno=...

Its content can be fount on a sticker on the Goflex Net. The original Pogoplug E02 boot environment is still on the device because a different address is used.

@kuduku,
can you please upload the boot log of the serial console and the boot env using command printenv? If you have something like the following original env from Pogoplug E02 you might not be able to boot from USB or rescue system anymore.

nandwrite /dev/mtd2 mtd2

nanddump and naddump older and newer versions have different options. So if a specific nandwrite is older, then sometime the option is not availbale and default to --noecc.

Before nandwrite, best if one always check the option

nandwrite --help

I am not sure if Goflex Net mtd2 will work on Pogoplug E02. The boot environment has one additional variable.

It should work for rescue purpose. But not ideal, because of the memory differences.

This is only relevant with Pogoplug service. So it's OK for it to be undefined.
