Might be old debug 1198282 could work on first revisions of HW's. :p

I got the boot log (will post if requested) but I was unable to get any input, by either typing 'debug' or '1198282'. I was also unable to get into uboot using methods described in the wiki and forum (pressing and holding '-' during boot, or '~' or hitting 'Enter').
