BBs remain the most secure mobile devices available. When one uses all of the available security features, one must suffer the consequences. In your situation, the answer is no -- once the wipe begins, it cannot be stopped. The intent is that, by failing too many times, the device has assumed it is no longer in the hands of the rightful owner...and wipes away all data so as to protect it from access by other than the rightful owner.
Occam's Razor nearly always applies when troubleshooting technology issues!
