The modding went so well on my beloved THD that I decided to buy a Series 3 off of craigslist. I upped the HD to 1TB and socketed it. Anyway, when I pulled the code off of the working PROM (3.16-rel), I can't find the gzip signature anywhere.
Here is what I find:
1F 8B 08 is no where to be found.
0x6D4C 00 00 00 00
0xB5C8 00 00 7F FF
The TiVo boots up and works fine.
Am I missing something? (I am new to this.)
UPDATE: I figured it out. The willem programmer I was using needed a jumper change when switching between the SST37 and SST39 chips. It would read all of the data but half of it would be corrupt.
