Unfortunately, holding the WRITE and < buttons doesn't bring up the Flash Update screen. Despite that, I've still tried sending the 1.12 and 1.10 uodates, from my MBP as well as an ancient Windows XP desktop unit I dragged out to try fixing this (although I only tried 1.13 from that machine). No change, of course. The screen lights up but no text appears and no sound passes through.

My first try updating to 1.13 also went wrong. It also said checksum error and the screen was blank after turning back on. Then I tried the update procedure with version 1.12 and it worked.
Is your unit yet responding when you hold the WRITE and < buttons while turning on ("Flash Update" message on screen)? If so, try it with 1.12.
Good luck!
