Pogoplug Mobile NAND messed up pretty decently :) (5 replies)

Here's my setup:
-Pogoplug Mobile (plugged in and activated to get in via SSH)
-Arduino Uno R2 as Serial connection, soldered

I've been 'playing' with hardware and software for quite a couple of decades, and thought I knew anything about what I'd normally consider 'normal' modifications, but this bugger seems to have confused the crap out of me!

Current status, directly from kwboot's serial connection:

===================================

The only thing modified above is the MAC - because :P

If ANYONE can help, here's what I'm looking at:

-I would LOVE to restore my nand back to factory defaults - back to the beginning - but although I have the mtd0-4 parts posted for the V4 boxes from here, I can't SSH to the box, so nandwrite isn't viable :(

-I have tried SEVERAL different uboot's (as follows) and all can't setenv... :(
uboot.2014.07-tld-1.pogo_v4.mtd0.kwb
uboot.nandpogoMobile-MMC-mtdparts-NoUSB.kwb
uboot.uartpogoMobile-MMC-mtdparts-NoUSB.kwb

-I CAN tftpboot and uartboot, but for the damned life of me cannot get an SD or USB stick to boot (most likely because there aren't images I can find and most directions prep the sticks/drives using files from the now dead pogo) :(


I know it's alot to ask - and for that I apologize, but any help would be so helpful!

I'll document everything and hell, if there's no bare-metal recovery directions, I'd LOVE to document that for anyone!

Thank you in advance!
