The other conclusion was that the mmc was totally fried. I never got around to building a serial cable to check any output from uboot. You see no output at all which supports the totally fried mmc conclusion. I boxed mine up and sent it back to the mother ship yesterday.
geekmaster was right about the battery, it could be that it is not totally charged in the bricked on. Could be the the circuits controlling the charging got damaged.
Could be a lot of things
If it were some 80s electronics, I could fix it probably, but those tiny SMD thingies and the equipment you need to even find the error and the manuals to sip thorugh....way too much work. Mine was the leftover after a replacement so shipping it dows not help, I will keep it for spareparts
