[Verizon HTC One (M7)] br0adband:
Alright, I haven't owned an HTC device in a few years now - the last one being the ultra-awesome still-to-this-day HTC HD2 (which I miss dearly) and yesterday I acquired an HTC One, the Verizon model. I've spent the better part of a few hours scouring threads, forums, posts, the usual rigmarole and there's one big question that I haven't been able to answer for myself just yet. That question is this:

What is the most current actual build of firmware for the Verizon HTC One?

The reason I ask is two-fold in some respects:

1) I'd like to make sure it's at the most current build obviously, and...

2) I don't use Verizon so it's not going to get an OTA if one is available so I need to consider other methods (RUU, perhaps, I'm really not sure since I haven't dealt with HTC hardware in some time).

It's not a bad device so far, I am somewhat irritated by the very thin display and all that "wasted space" considering I just sold my LG G2 which isn't all that much different in terms of overall size but it's literally edge to edge with that 5.2" display.

Anyway, here's some relevant info from this particular One that I acquired. From booting into the fastboot screen:

***LOCKED ***
M7_WLV PVT SHIP S-ON RH
HBOOT-1.57.0000
RADIO-1.13.41.0421
OpenDSP-v32.120.274.0909
OS-4.10.605.3
eMMC-boot 2048MB
Apr 22 2014, 18:03:29.0

Now, going by that it's obvious it's S-ON and until I cough up $25 for Sunshine I'm not going to be able to alter that status, I understand that much from all the reading I've been doing. Not sure what some of the other variables are but I suppose they're not relevant.

I'm guessing that date there was the build date of the device, or perhaps the build date of the firmware. I keep seeing mention of 4.10.605.2, 4.10.605.8, 4.10.605.10, and 4.10.605.15 but whenever I do a search for the *.3 firmware I currently show on mine, it's like it doesn't exist for some reason, I don't know.

Android version
4.4.2

HTC Sense version
6.0

Software number
4.10.605.3

I've wasted time trying to root it (and failed, as expected as I've learned) with Towelroot (think it did a temp once when I was testing Sunshine but Sunshine still said it had to do its own temp root, go figure) and rumrunner (there's no version match for my firmware build so I tried the *.2 release and had no success).

So for the moment I'm just in pause mode doing more research. The obvious end-goal would be to get this thing S-Off and bootloader unlocked to do some proper experimentation with various ROMs just like most any of us want to do.

But again going back to the main question: is the firmware build I have at the moment (4.10.605.3) the actual latest version available (I don't think it is) and if it's not can anyone give me a nod where I can locate it or figure out how to get this thing as fully updated as possible ?

I appreciate any responses or suggestions. I may just turn around and sell this M7 because I'm not really satisfied with it at the moment - that's not just because of the difficulty of getting it loaded up with different ROMs, it's various things that I don't find so appealing about the One at all compared to other devices I've owned.

Excuse my babbling at times, folks... Happy New Year to one and all and have fun, always... :)

EDIT:

Ok, not 5 mins after posting all this I found info about using HTC Sync to check for and install an upgrade and, sure enough, that's in process at this moment as I'm typing this sentence. My mistake there, no worries. Now the fun begins I suppose...
