Has anybody done an upgrade that didn't work.

I upgraded the 7200 MCP Boot Rom to 1.07. Then started to upgrade the LCP & MCP. LCP went to 4.17 without problems but when it came to the MCP 4.14, the system would no longer boot up. Looking at the MCP via Hyperterminal I got the following error

[Boot PGM] <<< Boot Program of OfficeServ 500/7200 System >>> V1.07:2007/058

Have reloaded the Boot Rom & tried v2.67, v2.69 & v4.11 but nothing works.

Spoke to our tech support (not directley to samsung) they recommended switching on dip switch 5, but still nothing.

Anybody have any ideas how I can get it to work without sending the card back.
