Failproof Unbricking Method For Sl-5000d And Sl-5500

[matrixcore]

Hi, to all the SL-5000d and SL-5500 users out there with a bricked zaurus
As you all know there's no way to make a NAND backup, just as you can with the SL-5600 and above.
But, there's another method, the JTAG interface.

I've succesfully restored my bricked SL-5000d using this method. I've bricked my zaurus by flashing a SL-5500 3.13 ROM onto my SL-5000d.
Only the diag menu was accesible, the unit would not boot overtwice. The flash memory was in good state (passed the checks)

All you need to have is the special JTAG cable, software to use it, and the original SHARP rom image (the 16mb file)

You can PM for more info

I tried to contact matrixcore, but had no success.

Anyone how has more information about this topic?

I have a Zaurus Collie (5500) and want to do a complete backup before i do large software modifcations. The 5500 has no NAND backup/restore like newer Zaurii and JTAG seems to be the way to go...

Thanks
Stefan

Maybe, the Openmoko Freerunner "Debug Board" could be used?

The doc http://wiki.openmoko.org/wiki/Debug_Board_...AG_using_FT2232 says

this allows the user to use this device as JTAG adaptor even for other arm-based devices

It may need a special JTAG cable though.
