Error 29 upon replacing battery, OEM battery not available

I recently replaced my battery on my iPhone 4s using the battery from iFixit. Before the new part arrived, I naively disposed of the OEM battery, and cannot retrieve it anymore to do the traditional fixes to Error 29. I have attempted to restore my phone normally, as well as through putting it in DFU mode. This has not worked, and made my device essentially bricked. Any idea as to how to continue? I'd rather not try to find another phone to attempt that fix, so I'm open to any suggestions!
