HTC 10 Unlocked International 64GB - Not to use Verizon radio (No Service)

First, @dottat - Thanks for your effort and guidance to the community. It is appreciated.

Now on to the issue. I have an HTC 10 unlocked international 64GB model bought on Ebay. I have flashed TWRP (twrp-3.0.2-6-pme.img), rooted (BETA-SuperSU-v2.74-2-forceencrypt), and s-off (Sunshine). Everything holds steady while I go through that process with the trouble starting after flashing the Verizon radio. When the Verizon radio is flashed and the phone rebooted, I receive a No Service message, the IMEI and baseband are "Unknown" to Android and phone will not recognize a SIM card. Further, when entering *#*#4636#*#* to select the proper radio, I am stuck in LTE/WCDMA and unable to change the radio band (Auto, USA, or so on...). The IMEI is still set in fastboot getvars.

I have tried to flash two different Verizon radios VzwHTC10_1.19.605.9radio.img and VzwHTC10_1.19.605.22radio.img. Both result in the same issue.

I can recover from this by flashing the firmware ZIP of the HTC OTA release which seems to be the version that was on the phone to start:
OTA_PERFUME_UHL_M60_SENSE80GP_hTC_Asia_TW_1.30.709 .1_R-1.21.709.2_R2_release_477314i6fyk64xlvy886ba

Does anyone have any thoughts on my next step?

Or should I be considering an attempt to return the phone or sell it at a slight loss and pickup an unlocked or Verizon phone from HTC directly?

Thank you in advance.

Mike

PS - I tried searching and reading many threads. I have seen this question or a similar one asked a few times but with no answer that I could find. Please be patient with me.
