Boot Loader Loop, Unlocked, S-Off, Rooted HTC M8 Tmobile

A year ago I believe I used HBoot and or Firewater to root my M8. I recently removed some applications that seemed to make my phone act funny, and now the phone is stuck in a boot loop, or rather just a boot and stop at the second HTC "One" screen. Not exactly a loop.

I've download ADB tool and tried the fastboot method to install TWRP but have no success because the computer does not recognize the phone while running ADB or Fastboot, therefore I cant install TWRP and am stuck in the bootloader menu. I have tried various different cables and restarted the pc several times, and installed htc sync and other drivers necessary for that process. Also uninstalled and installed different drivers later as well. Now im not sure what i have installed but I have access to the phones internal drive via explorer.

Using Hboot.

Recovery leads to nothing and eventually returns to the HTC One menu stop.

Reset does nothing, acts like fast boot actually.

Ramdump under fastboot seems to works, and does produce log files.

While the phone was still active, I managed to create a full "manual" backup of the device by plugging it in and backing up/copying the entire internal memory. After screwing with the phone and every option for several hours I managed to access the files of the internal memory by switching to recovery mode via the boot menu and then plugging in the phone via usb to comp while deleting the drivers at the same time. I tried a full restoration of the internal backup i made, by copy and replace if the same method, but still nothing.

Ive attached an image of the Hboot menu with the details and options of that Hboot for those of you familiar with hboot.

The ideal situation, or what i'd like to do is restore the phone without flashing the rom and loosing the information, then id like to upgrade to lollipop or a new custom rom I found here actually, but the first step is getting back into the phone which i would be very grateful for in general.

also, not great with cmd and all that stuff, I do have sdk tools downloaded and installed but not great with that either. If there was a more simple way to replace existing files in the phone via the file manager (because im able to access the internal drive via the file manager, that would be the most ideal and easiest situation. But knowing the path and the boot files and which files are necessary for boot is what im looking for as well.

Also i know how to flash a sd and htc has a sdcard slot as well. Also i should mention that prior to the phone being screwed up I did want to delete some internal certificates because i believe someone installed a spy application on the phone, hence the reason for all of this checkup and removal anyway. In the process of trying to do that, i followed a tutorial on this forum which suggested I create a security lock pin, which I did. This could also be the cause of the problem not being recognized by the adb or fastboot script.

Who ever helps me do that gets a tip.

Please help.
