To modify or repair the flash or flash hardware of a cam you may need some special equipment:
Programmer for the W29C040T-90 (This is a Winbond part Number - Full technical specifications)
A 32 pin SOIC Test Clip
Flash dump file (this file here is for an Euro Aston Ver. 1.04 & Ver. 1.05 only cam to FREECAM)
Flash dump file (this file here is for an Euro Conax Ver. 4.00 only cam to FREECAM)
A small tipped soldering iron (if you remove the IC)
An adapter for the programmer (if you remove the IC)
Now we will look into a
Irdeto
( P/N : 901453 )
( P/N : 901454 )
( P/N : 901633 )
Euro cams
have a 32 pin Flash memory chip called AT29C040 (This is a Atmel Code) and this
is a 4 Megabit (512 X 8), 5 volt Flash memory
(4Mb (512K × 8) CMOS PEROM, 5V only - 120ns
Access)
The IC is a
32T (32 Lead - Plastic Thin Small Outline Package . (TSOP))

The flash file will need to be read from an existing cam that's been programmed to work as a FREECAM
I also found the manufacture of this adapter at ICE Tech in Sheffield, England. There are many prices for this adapter, so shop around before you buy.

Now to use this 32 pin SOIC with the above programmer you need to solder some wires from the test clip to a 32 pin socket (see below) that can be inserted in the above MICRO PRO programmer. So below is the pin numbers of the TSOP IC thats fitted in the Cam and to the right are the pin numbers of a standard DIP package that will work with the above programmer. So you solder from the 32 pin dil socket to the above test clip 32 wires. then you can insert the dil socket into the programmer and program the 29C040 TSOP on board.
