Can you flash a different rom (older one) over a new one succesfully?
IE: same model. same year, etc just different rom revisions.

I am particuarly speaking of a 05 LGT AT. going from a 521C rom to a 510C rom. Is this possible?

Thanks,

Jason

No problem. There is no routine to check if the version u r flashing is older than the one you have in ROM.

cool, one last question..

Is there any kind of immobilizer code in the rom similar to the Evo's. Or are roms interchangeable from car A to car B (assuming they are the same model year trim etc)

Thanks,

Jason
