I've got a Verizon HTC M8 running DigitalHigh GPE 5.0.1 12/21 build, stock kernel.
I've had 4g issues with the phone since the first time I ever flashed away from stock. And the whole RUU back to stock and factory reset thing has never worked for me. The phone simply refuses to stay connected to 4G...
The first time I had the issue and I couldn't resolve it I called Verizon. Was sent through to tech support, who "opened a ticket" and told me I would hear from them once it was resolved. Never heard from them, but the issue did go away on it's own and the phone connected to LTE once more on its own. I was running BoneStock ROM at the time (this was back in August 2014).
Fast forward to November and I decide to switch to GPE and I start seeing 4G issues again. My phone would connect to LTE at first boot but once my Sim "activated" it would only connect to 3G from there out. I tried everything to get it back. I did RUU back to stock and factory reset, I flashed new radios, etc...
Finally I activated a new SIM that I had laying around and BAM! LTE service again.
... For a few days. And then back to 3G only.
I used an app called 4G switcher to force my phone to connect to a 4G signal and when I did that it showed that I was roaming... So I would dial *226 and update my roaming list and it would no longer say I'm roaming and would say I'm connected to LTE... For about 10 minutes and then back to 3G only.
I went to the Verizon. Wireless store today and they gave me a new sim and told me to call prepay customer service to see if I can get a warranty replacement. The new SIM instantly connected to LTE and has been connected for almost 6 hours now.
Is there something wrong with my phone that it keeps frying the SIM or could there be an issue with my account on Verizon's end, maybe something telling it to reprogram my SIM to not connect to 4g?
I have used my phone overseas for a month with a European SIM and a service that was only 3G, not sure if that would be relevant at all.
