unbricking?, my sl5000d is in a coma Options

[saakmotu]

I've read the threads here (and at other boards) and I can't get any of the proposed solutions to work for me.

I have a sl5000d which I managed to render unbootable/unflashable.

When I try to flash (from either C+D or Diag Menu CF Update) both LEDs get stuck on. I've left it that way for hours.

The only thing I haven't tried is to reformat my CF card (I have to put files onto it from a WindowsPPC device) but I've previously flashed from the same card. OZ worked in the past, and I tried it before attempting OSPACK.

Right now, it's stuck with both LEDs on with OSPACK for ROM 1.02, the oldest I could find.

I can still get the Diag Menu, so I'm not looking at a 100% brick, but it's pretty close.
Also, my Diag Menu used to have 4 pages, now it only has 3.
clicking on "Version" in the bottom right does show the ROM as USA 3.10.

I'm going to pick up a CF card reader/adapter so I can plug the CF directly into a Linux desktop/laptop and reformat, etc, but I can only hope that makes a difference.

During my quest I've read that in the most extreme cases that a Z can be sent back to Sharp and they can use something (starts with a J...??) to revive the unit.
Is there any way for a normal (read: non-Sharp) person to do this? Sure would be nice, wouldn't it?

Thanks for any help and good luck to others who find themselves in a similar predicament.

here's the response I got from someone at the openwince-list
at least I'm facing the right direction.

You need three things:
1. bootloader's binary
2. JTAG cable
3. JTAG connector (or pads) on the target hardware (zaurus)

Then it could work.

But, you are writing that you could see the Diagnostic Panel. I've no
experience with the Zaurus, but it sounds like software name. In that
case you probably already have working bootloader in the device. Only
target system (operating system image) is broken.

Using JTAG you could reflash whole flash memory in the device, but it
is slow (depends on JTAG cable, ...) and you need binary image of the
memory.

does anyone know how I might acquire a "bootloader's library" ?
or a JTAG connector for the Zaurus?
I think I can figure out where to get the cables... else there are a few sites with instructions on building your own... (not so sure about doing that, tho)
