I have a Verizon HTC One. I have PAC Rom installed. It's the jelly beam version. I tried flashing the paranoid android kit Kat beta. After installing I would get no service completely and when going to settings and into networks, I clicked something and it said there was no sim card. so I went back to my backed up jelly bean PAC rom. then I tried installing the new PAC ROM (kit Kat) with the same results, no service, no Sim. ( note: when flashing it failed to flash the PAC ROM m7vzw, but it did flash just PACm7 with no specific service provider).
Another thought, I can only run TWRP 22.214.171.124, I have tried 126.96.36.199 and 188.8.131.52, when I flash those, it does not go into recovery, it fails and goes into the regular boot. So then I have to fastboot 184.108.40.206 back to get into recovery...
You flashed a Gsm Rom on your Cdma phone.
That's why you have no service and no baseband.
At this point, I suggest you flash stock rooted Rom and stock recovery.
Then in settings of stock Rom, perform a factory reset to restore your NV radio partitions.
Only stock recovery will fix this.
Then you must flash a recovery for the Verizon HTC One and a Rom for the Verizon HTC One and you should be fine...
Don't flash roms for other variants.
Back up anything you want saved from the storage, it will be wiped clean.
