iPhone stuck in Recovery Mode

Hey all! So, several months ago, my phone started respringing every couple minutes, for no apparent reason. It got to the point where I couldn’t use the phone for more than ten seconds without it going black, so I tried to restart it a couple times and eventually ended up putting it into Recovery Mode. However, when I tried to update it from iTunes, I got various errors telling me that I needed to restore it instead. Unfortunately, I didn’t have a recent backup of the phone, so restoring it wasn’t exactly an option, and you can’t back up a phone while it’s in Recovery Mode. So, I tried to get it out of Recovery Mode to back it up, but it wouldn’t exit. I’ve tried every solution from the Apple website and numerous third-party applications to get it out, but nothing has worked. It’s been stuck in Recovery Mode ever since, with me unable to get my data off of the phone. Today, I decided to try disconnecting the battery to see if anything would change- unfortunately, it didn’t work. Do you have any ideas of what I could try next to get the phone into a state where I can back it up?
