after reading several threads in this board I cannot find any solution for my Problem.
It is a Xenon box with CB 1888. I could boot Xell and the old orignal dash and got CPU-Key.
After that I have noticed that ethernet is death and I do not have removed R6T3.
So removing R6T3 and install missing resistor R1B9 in TX_CLK of ethernet chip ended up in ROD 0022.
I put all back to the original state, but same error 0022. The error occurs 30-40 seconds after starting the box.
Now Xell original NAND and or XBR or freeboot will not boot into dash.
Reading CPU post code @FT6UX gave me 0xA8 or 0x15 depending on pin count
Now I do not know where to find this code to check what is wrong with this Board?
Did I fried the CPU or Southbridge?
Anyone who can help?
