I tried searching them all by date, but if I go deep enough into the 401 folder (most recently modified) all the files have a last modified date of 2008. Very confusing, would anyone be able to steer me in the right direction?
Are you S-Off? If so you can just flash a firmware zip.
If not, you can either go back to stock ROM and recovery and take the OTAs, or you can run the WWE RUU.exe file to update.
Depending on your firmware version, either way works. If you are on old firmware though, you will have to install the OTAs one at a time. But if you used the RUU, you can jump right up all at once. It does wipe your phone though.
I suggest getting S-Off if you aren't already. Sunshine is the only way to do it, and it costs $25, but is totally worth it. Then all you'll have to do is flash the appropriate firmware zip, and it's super easy to do that.
