Phone will not turn back on, error 27

Question

     Hi, my iPhone 5c shut down randomly and will not turn back on. So, I put it into recovery mode, tried updating to 8.1.2 with iTunes like 10 times. It always gives me, "an unknown error occurred (27)" I really really don't want to return it to factory settings, because I'm an idiot and didn't back it up recently.
Specs:
OS X Yosemite
Version 10.10.1
Processor: 3.06 GHz Intel Core i3
Memory: 12 GB 1333 MHz DDR3
Graphics: ATI Radeon HD 4670 256 MB
Not sure which version my iPhone is on, but I was trying to update it to 8.1.2.
     After going through this page, I went through the vast majority of troubleshooting on this page for error 27.
     If I need to go to an apple store to fix this, that's fine. I ultimately just don't want to restore it to factory settings.

If you went through the steps in the support document about the error, then the final step is Apple Support.
Check for hardware issues
Related errors: 1, 3, 10, 11, 12, 13, 14, 16, 20, 21, 23, 26, 27, 28, 29, 34, 35, 36, 37, 40, 1000, 1002, 1004, 1011, 1012, 1014, 1667, or 1669.
These errors mean that your device or computer may have a hardware issue that's preventing the update or restore from completing.
Check that your security software and settings aren't preventing your device from communicating with the Apple update server.
Then try to restore your iOS device two more times while connected with a cable, computer, and network you know are good.
Confirm that your security software and settings are allowing communication between your device and update servers.
If you still see the error message when you update or restore, contact Apple support.
What can you see on the screen? Are you able to use the device? Is it just that you cannot update it? If you did put it into Recovery Mode as you indicated earlier, then you have already lost the data.
