HTC One M9 Stuck on splash screen after attempting update

My phone's bootloader is locked, never messed with it at all.

So about a week ago I get a prompt on my One M9 for an update. I download it without problem, however while installing it gets stuck at 25%, and gives me a red ! in a triangle, then it reboots. I try to redownload a couple times with no luck. For a couple days I just click don't install after it downloads (why isn't there an option to just not download from the start?) and finally I try it again on Friday morning. This time the HTC One splash screen comes up, and it freezes. I research for a couple hours with no luck. I have a wedding out of town I need to go to, so I decide to wait until I'm back home today to work on it some more.

Today I get back home about 6 hours ago and all I'm trying to do is recover my data, specifically pictures from my wedding. I thought I had it set to auto backup, but I guess that was my One M8 I did that to. I look into TWRP, which won't work because of the locked bootloader, various programs to recover data that won't even work on old phones that I have, as well as "adb -d pull sdcard/ C:\RecoveredData". When I attempt to do that it gives me the error: closed, even though when I type in ADB devices, my phone shows up, although it says sideload next to the SN. I looked up how to fix the error: closed (update adb.exe), but I get the same result, or it freezes (I've left it up for awhile just to make sure it wasn't copying the files)

The only way I can get the ADB commands to work is if I go into the Android Recovery and select "Apply update from ADB". I'm wondering if that is why it says sideload next to my phones SN and why I can't pull the files off of the phone.

I'm wondering if I apply the update that the phone was trying to get via ADB, if that would allow my to keep my current data. Looking at the page
ok, so I can't post URL, but if you google "Flashing a stock Android image without wiping user data", its the first post.
It appears that I should be able to. My problem is that I'm terrified of wiping my pictures out if I do it incorrectly.
I'm on Sprint, and the newest version is 3.41.651.13. I'm pretty sure my phone had 3.41.651.4
I just want to make sure that if I follow that post, with the correct files from sprint, that it would work.

Any help at all would be wonderful.

Edit: I did have USB debugging active before all this happened as well
