Help Recovering Pogoplug v4 with serial console and tftp (15 replies)

Hi all,
I need some help restoring the original firmware on my Pogoplug V4 (A3-01). My actual situation is that I can only boot into uBoot. I don't have a working o.s. on the nand and I can't manage to boot any other o.s from usb or mmc. Luckily I have both access to the serial console and mtds backups. Now my question is: how do I use these backups to restore my device? How I know where to write uboot or uImage? How I've to calculate the offset of nand write command? Are all mtds in sequence? Can you give me some examples? I don't even know if my $mdparts is correct but maybe this can help!(?).
