Hello Everybody!

I am having a problem here: I had a working gta04 A4 until recently.
Then I updated the NAND-part using these
http://download.goldelico.com/gta04/20130130-GTA04-last-2.6.32/ files
and instructions. Everything went well until after running step 14 the
device did not boot anymore.

Now when the battery is inserted absolutely nothing visible is happening
(no leds, no light or penguin on the display).

Battery is quite full. It shows 3.9 V on my multimeter (using the 9V
battery testing mode - i.e. with a light load).

I have a serial cable. If I connect this and insert the battery with
aux-button pressed I get a "60" from the device on the serial port.

If I connect the USB-cable as well I get in my dmesg:
[ 5770.660136] usb 2-2: new full speed USB device using uhci_hcd and
address 8
[ 5770.798297] usb 2-2: not running at top speed; connect to a high
speed hub
[ 5770.814298] usb 2-2: New USB device found, idVendor=0451, idProduct=d00e

[ 5770.816665] usb 2-2: configuration #1 chosen from 1 choice
[ 5773.856178] usb 2-2: USB disconnect, address 8

I tried serial-booting
(http://projects.goldelico.com/p/gta04-main/page/SerialBoot/) but with
no success:

hermann at laptop:~/gta04/serboot/prod$ ./pserial -p /dev/ttyS0 -f s-load.bin

ASIC ID Detected.
Sending 2ndFile:

Here it hangs with no further progress. Transfering 11kB over
115kbit/sec should take about 1 second, shouldn't it?

Any ideas what I can do?
Is my device broken?

Greetings
Hermann
