Bricked C3000, unresponsive service menu Options

[puffy]

I have botched an upgrade to OpenBSD 4.2.
As it happens, I need to use my service menu to fix things.

I noticed when I bought this c3000 off of eBay that if I did not hold down D+B on powering up that this menu appears. It is totally unresponsive at this 1-4 menu in Japanese. I mean, no key works. I cannot select 1 2 3 or 4. I assume this is not normal as I read that at this menu you must select a number. But at that point I cannot do anything but reboot by taking out the battery and unplugging then replugging. Has anyone experienced this? All replys are welcome. I am bricked :-(
I miss my Zaurus a lot. Please help.

As cortez said, you really should not worry. The Z actually has 2 NAND chips, one is the 128MB flash (/dev/mtd1) we use for OS and the other is a 8MB (/dev/mtd0) chip that is only used by the diagnostic menu and the original bootloader. As long as you don't touch the contents of /dev/mtd0, your Z will be practically unbrickable. AFAIK the 8MB chip is read only so i don't think that you can write or delete something. And again, as cortez said, use the FN + D + M. to access the diagnostic menu, from there, you can do a flash restore which will reset your Z to factory defaults.

And i'll say it again, it is really hard to brick your Z via software methods. If you really want to brick your Z, use coffee as cortez did.

Oh please don't mention that, it still hurts
