In the future, could you use a more descriptive subject for your thread? "New help" isn't very informative. Having a better subject line will get you more relevant views, possibly faster answers, and helps other people find your thread when they're looking for the same answers. Overall, it makes the forums better. "Can I restore to original firmware?" would be a good choice.
You make no mention of your drive type, so all I can say is get the newest JungleFlasher tutorial, follow through for your drive and look for something like 'Return to Stock'.
Thank you for your help!
