iTunes Restore Error 28 - Post Battery replacement


Originally, I ordered an iPhone 3GS battery for a 3GS I used to use as a daily driver. Recognizing that the 3GS had a defective display assembly, I switched out the new battery to an old 3G I had but never used. I know nothing about this 3G except that it didn't work. It looks in great condition. I don't know what version of iOS it was on before it stopped working, and I don't know what caused it to stop working whenever it did.  After re-assembly, I pressed the power button and the apple logo appeared, almost immediately switching to the iTunes recovery screen. Connecting to iTunes and restoring caused it to download ios 4.2.1 and attempt to restore it.

# It turns off
# Turns on 
# Loading circle at the bottom
# Software Update progress bar appears empty
# Loading circle re-appears and it turns off
# Turns back on to recovery screen

iTunes says "The iPhone 'iPhone' could not be restored. An unknown error occurred. (28)"

I've tried:

# Restoring after putting phone into DFU mode
# Custom firmware (.ipsw) in the form of whited00r71 normal edition which required using redsn0w  0.9.14b2 to launch in "Pwned DFU" mode for custom firmware install with itunes.
# redsn0w's "Recovery Fix" feature

I always end up at the recovery screen. Here are my software specs.

* Windows 10 x64 Pro Edition
* iTunes (32-bit) - Had to downgrade from the latest iTunes in order to get the libraries in the right directories for redsn0w to use "Recovery Fix", but I did try to restore with the latest version of iTunes before I downgraded.

Again, I have no idea of the circumstances surrounding this phone's retirement but I'm not willing to spend more money than I already have on the cost of the battery replacement from iFixit. If it's truly a hardware issue, I'll call it a day. I would love some software fixes/recommendations or possible hardware things I should check or do.
