Kindle 2 - Won't update.

My coworker had a broken 2nd Gen. Kindle that I offered to try and fix. Turns out the battery was dead, I replaced the battery and booted it up.
The downside is the kindle was running version 2.1 and I couldn't access the kindle store. So I followed the directions of Amazon's website to manually update the device.
Downloaded the 2.3.bin and when I ran it, it stopped halfway through.
Now the device is updated to 2.2.2 but I can't seem to update it any further.

I read on another thread how to get the logs of the device and i found this part with the failure

160529:185220 ota_install: I def: patch: patchinfo="/usr/java/lib/libAdobePDFReader.so": patching file

I'm not really sure what this means or how to try and fix it so I'd appreciate any help
