Sounds like you have a nice mixup of software on the device. First and most 
important rule:

== The PCB does not lie. Your device _is_ a GTA02v4 ==

Second rule: Don't flash a non-matching U-boot into the device (which you can 
do via the debug board).

If you can get in the boot menu and have access to dfu-util, then try to 
upload a current bootloader for v4. If not, you're out of luck and need the 
debug board to flash a v4 bootloader.

Afterwards, you can resume with flashing GTA02 kernel and images.
