I tried to flash U-Boot and now my gta04 does not react any more. If
anybody has an idea how to unbrick the device or can tell me what I did
wrong, please let me know.
Here is a description of what I did:
Using "makesd gta04 debian", I wrote data on a sd card. The sd card was
put into the gta04. After reading in this post  how to flash U-Boot,
and after several attemps  the red flashing screen appeared. The red
color flashed only for some seconds. After that the gta04 screen showed
a picture which looked like a tv showing a dead channel. The dead
channel picture did not go away for some time, so I powered off the
gta04 by pressing the power button for some seconds.
Now I am not able to power on the device. I tried various combinations
of pressing the aux and power button, with and without an sd card (with
a 4 year old working qtmoko) in the device.
The battery is not empty. I use a gta04a4.
Thank you for any help and regards
There is written "boot with this SD card (with pressing the AUX
button)", which did not work. It led me multiple times I believe to a
standard boot (in my case to the menu with SD1 to SD4, NAND, OFF, Button
LED, Blink, Touch etc.).
 What led me to the red screen was:
1) Push the power button to power on and release it.
2) Then push and hold aux and additionaly push and hold the power button
I thought I have to do this with, because the webpage
http://projects.goldelico.com/p/gta04-rootfs/ says "install the SD card
and boot from peripheral (press User/AUX button if required)" in chapter
"Install X-Loader and U-Boot in NAND flash".
