Thanks, I'm considering to obtain a new one. Played with my semi-broken and found an interesting moment. I played around diagnostic menu and make this – first attempted to NAND Erase (anyway it's nothing to lose for me), got an error (ecc related, as I can remember), then activated option NAND Read&Write Rpt. Strangely, but this thing worked – procedure was ended without error, and after this option NAND Bad Blocks says it's none founded and everything is OK. But device still not working properly – after choosing "EXTRA" – "Zaurus Test" – "Reset" (or "Off") no reaction to pressing on "Power" button and both LED constantly on (not blinking). After removal of battery it even stops doing this, and only reboot from diagnostic menu returns LEDs to work. Also tried to run NAND CheckSum, and got NG status on positions ROFLSYS and PRESET. Tried to flash NAND Backup, downloaded from Trisoft.de – it's restoring without error (only from 1 Gb SD, CF still not working), but no help at all, device is still dead. It's definitely a hardware issue?
