[Q] Cannot upgrade droid dna ota - HTC Droid DNA

Hi All,
i have been at this a few weeks , so finally posting a thread.
i came across what appears to be a pre-release device (new in box) and want to get it updated ( it had a pre-release OS loaded - version 0.68ish )
i managed to force an update to 1.15 with the RUU image .
the device now works fine, but it will not look for OTA updates. When i manually try to check, it flashes briefly it's looking and then nothing happens.
i have tried reloading the RUU and hard resets to no avail
i tried loading the 3.06 RUU out there, but the RUU fails as it is apparently incompatible with a straight upgrade from 1.15 and i cannot find a 2.04 or 2.06 RUU anywhere to be able to stair step the upgrades up the ladder.
i would like to get this device upgraded to the newest os version. not exactly sure how to do it. ( not sure if i have to root, then upgrade to a certain point then unroot or what. ) i would prefer to end up with a non-rooted device running the most current factory version
i DO NOT have a Sim card installed, (but cant believe that would be an issue- then again its verizon so i guess i actually wouldn't be surprised )
here is the Boot screen info;
***Locked***
MONARUDO PVT SHP S-OFF
CID-VZW-001
HBOOT - 1.33.0001
RADIO - 1.00.00.1023_3

iirc, the ota update is from Verizon. Therefore, you would need a SIM card and service to receive them.

So i tried installing a sim card. that did not help.
i pulled a different device out of a box and checked the boot screen... it does have different info, ( highlighted in red below)
i am wondering if i have to somehow force S_ON back on to this device and/or get rid of the CID_VZW_001 info, to get it to take an OTA
thoughts anyone on how to do that or a link to read?

hmmm, cant get the brand new one to take on OTA either.
i did not use an active Verizon sim, just a recognized one. so maybe i do need an active one in the machine.
their website says updates can be done over wifi, but maybe the sim still needs to be active.
i will check this

Install HTC Sync app. Start app. Plug phone into PC, give it a little bit for HTC Sync to recognize the phone. An update pop up window should appear. Update.

Solved!
well well well,.... i had no idea sync manager /verizon allowed updates via PC.
Thanks so much for this!!!
I did have some troubles getting the upgrade. The upgrade assistant kept failing and giving me an upgrade unsuccessful message while downloading the update. i finally went into the control panel and turned off autoplay as it looked like the device kept trying to load usb drivers during the download even though it already had them installed and that appeared to be causing the computer to lose its connection to the device .
this was all done without an active Sim installed.
