No one.

The GMS80c501 is mask programmed during manufacturing with the software 
for the receiver in ROM. You need exactly the one G088 that contains the 
program for your device. No one wil deliver that. The only way is to 
salvage one from the eactly same receiver that has a diffetent defect.

Buy a new satellite decoder (or ask, why exactly this part should be 
defective).
