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.
