If you don't have your SHSH blobs, you're basically SOL with restoring to previous firmwares. The only fix to remain jailbroken/unlocked is to have your SHSH blobs saved on your computer or with Cydia.

You're never suppose to do "erase contents and settings" when you're jailbroken. It will always cause a problem where you'll be stuck on the apple logo. Again, if you don't have your SHSH blobs saved, you'll be forced to update to get it in a working condition.
