HTC Desire stuck in a bootlop

I joined this site specifically because while searching for a solution, I discovered this thread
https://androidforums.com/threads/htc-desire-610-bootloop-unrooted.1058186/
I am having an identical problem to that user. Every fix, every stumble, it's exactly the same.

I woke up one night and my phone was booting up while charging. I thought it strange. Since then, it's been caught in an eternal boot-loop. And everything that's happened to me is the same as in that thread (only, it seems no solution there was found). I'll put in here as many specific details as I can, but for anybody that can help I also implore them to read that thread because it really covers ALL of the things I've tried that have failed. It's a complete 1:1

The phone turns on, loads up for a few moments, but before anything has sufficiently started up, it immediately reboots. And it will just keep doing that over and over again until I physically pull the battery out.

Generally I get a few moments of time when it loads up. It will never let me manually shut down/restart/run safe mode. That menu wont open when I press down on the power button now. I can move my apps around, open some of them for a few seconds, even uninstall one in the short window of time before it resets itself, but everything ultimately ends up back where it was on the next load-up. It would also seem that the app I choose to open will determine how quickly it chooses to restart.

If I leave it off and plug in the charager, it will charge up fully. Then if I were to turn it on and let it do its bootloop, it'll do that for hours or until the battery overheats. Plus occasionally before the phone reboots, it gives me a crash error on some random app before shutting itself off.

At the very least I'd like to know what program would read my SMS backup files from HTC. Because it sure as hell wouldn't work on any web browser or in a Samsung.
