I made "NAND restore" with SL-C750-ENG-NAND-original-1.0.zip from
http://downloads.conics.net/pda/zaurus-sl-c700/service-menus/.
Then in the service-menus i cannot update my rom. when i press
update(cancel, error check, format) button, the lcd became black.
Worsely, I cannot enter the DM mode to restore my backup DBK.
What should I do?
