I seem to have bad luck with PDAs. I broke my iPaq putting Familiar on it, and now I've managed to turn my Zaurus (SL-5500) into a brick.
Don't ever try swapping batteries in the dark. There's no way to tell which way it's facing. I managed to put mine in upside-down. The unit won't power on. Plugging in the AC adapter makes the charging light go on for a few seconds, then it goes out.
I tried reflashing (OpenZaurus 3.3.5), and it goes through the process, but it still won't turn on. Haven't tried any other ROMs yet. I read elsewhere on the board that you can fix a bricked Zaurus by reflashing with the original Sharp ROM. Haven't been able to try it yet because I only have a 16mb CF card.
Is there any hope, or am I gonna have to send it back to Sharp?
