I used rrgn for regions 5 and 14, and my SD card looks exactly as the files you uploaded - it's been already posted on this forum, how to do it. That's why I asked if somebeody has tried and succeeded reading a region on Oregon 6xx. I'm aware that the 600 is different from 650 - at least hardware is different. The firmware is the same and the chipset is the same, only the functionality is different (based on some configuration).
Is there anybody who has tried running any commands by ldr.bin on Oregon 6xx?
