GoFlexNet bricked

Hi there,

Think my GFN is finally bricked.
Here is what I did, from scratch:
Main reason to order this device was to build a SqueezePlug, so I followed the SqueezeboxWiki instruction SqueezeBoxWiki. Preparing the USB stick was easy, the bootloader has been replaced following GFNImage and arcNumber was adapted.

Boot from USB stick went fine, last step of the wiki is to install the Rescue System to NAND. At step:
fw_setenv rescue_bootcmd 'if test $rescue_installed -eq 1; then run rescue_set_bootargs; nand read.e 0x500000 0x100000 0x400000; bootm 0x500000; else run pogo_bootcmd; fi
I've got the "Too few good blocks..." response, I was seeking for info on that and learned here: Newer uBoot as workaround to 3.2 kernel problem? that a new uBoot would help to resolve that problem. So, I set up UART and netconsole and successfully installed
uboot.mtd0.kwb-2011.12-goflexnet-L2Coff-IDEpatched.kwb .
That went fine:

But now, the GFN didn't boot from USB stick anymore, even after setting the arcNumber to 3089 again.
Next, I was trying to boot from USB manually, using the USB boot variables I found in
GoFlex Net not booting from USB Stick. Dockstar does! .
But it seems that I mixed something up in the uBoot env settings:

GoFlexNet> usb start

From that post: Re: Restore MTD backup via serial
I deduced I might need to install uboot.UARTgoflexnet-IDEpatched-netconsoleON.kwb to fix this.
So I did:

From here onwards, the device doesn't respond on UART connection (Windows Hyperterminal) and the status LED remains dark. The system is still consuming power (4 W) but I assume it finally mutated into a zombie :-(

Could someone tell me at which point I made the deadly mistake?

Looks like it's fine until this point, the error can be fixed by setting usb_bootcmd and usb_boot envs to correct values.

I don't think you need to flash this image: uboot.UARTgoflexnet-IDEpatched-netconsoleON.kwb. The previous one works fine, but I think the envs were not for USB booting. You're actually flashing debugging uBoot images created by Davy. It's best to flash his final uBoot image that you can find from Jeff's installation script [url]http://projects.doozan.com/uboot/install_uboot_mtd0.sh[/url].

To unbrick this zombie, try UART booting instruction:

Thanks, bodhi,
but I'm afraid I can't do anything any further, since I don't receive any single bit via the established serial connection anymore. Didn't try netconsole yet but afaik it is activated AFTER the serial connection. I guess the first stage bootloader is somehow gone.
