Sharp ROMs / My SL5000D after flash ROM,can help?
« on: May 14, 2004, 01:49:14 pm »
I still feel stupid, but at least I\'m in good company. Problem: I don\'t have the $$$ to upgrade. I just finally got this one!
I have a SL5000 which I admit to have been rather stupid with.
I have been frustrated with Sharp for not putting up their Dev site
where I can get updates for the 5000.
In my frustration I have renamed \"ospack\" to \"romimage\" and flashed the
unit using the 5500\'s train of flash.
It flashed correctly, and upon boot I get the Sharp screen and init 2.78
message then nothing. Switching the Battery Mode switch back and forth
once I then boot into the same message as shown(below).
Hard reset sends it back to the original Sharp/Init screen.
Now, however I seem to be unable to flash the device, getting the Green
light stays on as long as I let it. This happens when attempting to
flash OZ3.2 or the Sharp 5500
One of the FAQ\'s I was reading says that means the FLASH device is not
useable (although I\'ve used it before??).
Could this mean that the flash corrupted the bootloader such that it
doesn\'t understand the CF card any more? I\'m lost. Would you have any ideas?

This problem has nothing to do with the bootloader, and if you
~ _intentionally_ overwrite it, you _will_ brick your zaurus.
