It's a little out of date, but your firmware is Marantz. Latest for a 5000 is Sys 4.92 and App 5.2. Latest firmware for a TS-1000 is Sys 3.62 and App 4.85, so you can't be running 1000 firmware, and 2000 firmware won't load to a Marantz under any conditions.

Ccf's are loadable into any of the old version remotes. Doesn't matter if they were created for a 1000/2000, any of the comparable Marantz's, a Chad or RAV. You MUST, however, use the appropriate software to actually download the ccf. I.e. Touch Screen Setup for a Marantz.

If the original ccf was for a 2000, and the ccf is "corrupted" and reboots, it MIGHT be an unnamed code in the ccf. The 2000 software had a bug where if you copied and pasted a code, but failed to name it, the ccf was corrupted. I BELIEVE (but am not certain) you can use latest versions of TSS or PE to go in and give these codes a name so that the problem is solved. 'Course first you have to find them.
