It's hard to tell. Since you have a customized ROM it could be the ROM itself or it could be the recovery your using. I'm not all that familiar with Hyperdrive ROM but I'd go to the developer's website or where you found the download link for the ROM and see if others are having similar problems with GPS, there may be a fix. I don't know what custom recovery you're using but that too could be the problem. I've read that some recoveries will flash a ROM or Kernel just fine while a different recovery will not flash with with same success. I found that out myself the hard way. If you can't find a solution to your GPS problem through researching threads pertaining to your ROM then you might try a different recovery.
