[Q] Cannot send/receive texts and many other issues topic

Hello and thanks for the help. I've got a Verizon S-OFF/Unlocked HTC One M8 (USA), and I've been flashing different roms found here for a while now. After flashing a lollipop rom (DH GPE version) I realized after a week or so that I wasn't getting 4G/LTE anymore. I tried switching network modes etc but I could never get 4G. I decided it would be best to do an RUU to get back to the basics and make sure it would still work on the stock rom, but I performed the RUU from this thread: http://forum.xda-developers.com/veri...ewest-t2914914 and I still couldn't get LTE. I then took my phone to Verizon and had them give me a new SIM card. They couldn't get LTE to work either. After this, I flashed an old backup (I believe it was a GPE edition of 4.4.4) and LTE was fully functioning, but after a few hours of use, I couldn't receive any text messages. I could send SMS and MMS texts and they would send/be delivered just fine, but I could never receive any in return. I tried this in both the standard Messages app as well as Google's Messenger- same thing. Many Sense based roms no longer work on my phone. What happens is on the initial boot, instead of going to the "HTC Setup" page, it just hangs on a white HTC Logo where the back and home buttons are present but don't function, the nav bar is visible, I can change volume/use power button settings, look at the lockscreen, but can't get to the home screen. I end up having to use the APM to get to recovery and flash something else.

In a nutshell: NO Lollipop roms will give me LTE, RUU back to stock didn't get me LTE, new SIM didn't get me LTE, most Sense based roms fail to completely boot, old GPE 4.4.4 rom (backup) and other GPE 4.4.4 roms give me a fully functional phone with LTE, but will not receive text messages (can send them) or will allow me to do both for a few hours but then stop working. I should mention that in the Sense based roms that do boot, I can send and receive messages just fine in CDMA mode, but obviously don't get LTE, and when I switch to global, I get LTE but can't receive texts. The last thing I tried was a full RUU and then a factory reset from the bootloader. This didn't work either.

At this point, I would love to just have a completely stock phone that is fully functional.
