860 Bricked By Uboot?

[conundrum]

I've been running pdaXrom on my 860 since I got it, and I absolutely love this distro.  That being said, after running on an older version for a while I finally decided to upgrade.

I put uboot on a 128mb CF card, went through the install, and then my 860 wouldn't shut down properly.  It just locked up at "The system is powered off" with the backlight somewhat off.  I pulled the AC and battery out, it booted into uboot's emergency mode.  After I tried the reboot command it locked on shut down again, and I pulled the AC and battery again.

Now my 860 won't power on, the power light won't even turn on with the AC in.  I know the cord is working (I tried it on my old 5500), and I have no reason to believe the batteries have suddenly gone bad.  If I remove the battery and plug in AC power, the light will blink on, then off again.

D+M power on doesn't seem to work, nor does OK + power on.

Try Fn+D+M

Fn+D+M did nothing.  The power light isn't even on when it's plugged in.

To clarify:

With the a battery in, the power light will not come on when it's plugged in.

With no battery in, the power light will blink on at first, then turn off.

Did you try leaving all power sources out for 10-15 minutes? It seems that that helped here:

Fn+D+M *will* work, flashing cannot overwrite it as it is in P2ROM.

Take the battery out and unplug the AC. Hold down Fn+D+M, insert the AC, then KEEP HOLDING Fn+D+M. It will take anywhere from 5-20 seconds before anything happens, then it will boot into the diag menu. Put the battery back and lock it in.

I thought the previous poster meant Fn+D+M and power on.  That worked, but now should I restore an original Japanese NAND, or...?

Is it uboot that's preventing the battery from charging and the device from booting?

Edit: Update, I've flashed on an english 860 NAND, the power light is on, and I'm letting it charge up.  After this I'll install one of my older pdaXrom versions to make sure everything is okay.  Any idea what I did wrong with the uboot flash?
