I also did a dirty build (without 'make clean') and then it said: "NBH ... can not find system on NAND partitions"
I've just do another clean build and will test again soon.
Another problem: in the last kernel I loaded from htcdevs.wirelesstcp.net/files/xdandroid/ it seen not load correct keyboard map for my RHOD500. Where I need mod to correct that?
Sadly, I was also has dead loop caused by do a fresh install while battery low
Just bought an external multi charger to save it LOL
