Oh yeah..

Have you installed the car2-developer image for v2-final yet?

If not, do so, If that succeeds in installing, then the issue likely is NOT the SRAM, but rather some corrupt data somewhere.

In which case, delete the database files and let the player try to rebuild them. If that fails, then you can always rerun the disk builder to wipe everything clean and start over. Sure beats replacing the SRAM..

Cheers
