Please let me know if you find out. I was wondering the same thing!
Let me try to help you guys.
What you guys need to do is to flash the original RUU for 1.27.531.11 from PC. Once you do that, you will be able to update OTA.
If you have unlocked bootloader and s-off, it will still carry over to the back to stock as well as OTA.
If you dont like it, just flash the older hboot and then recovery and another ROM.
I did it and works perfectly fine. Also no Root allow for Back to stock or OTA, you can do that later but not when trying to get update.
No custom recoveries, radio, boot, etc. Has to be stock ROM.
Ah, also please have sure the MID / CID is right before flashing to stock.

Unfortunately that only works on a Microsoft Windows computer. It won't work for Linux or Mac.
Are there any option for Linux/Mac users?

This is what I did. I was on a custom ROM, but -off, flashed 1.27 RUU, set basic settings up, then downloaded 4.3 update, still unlocked and -off. Painless.

The 1.27 RUU is stock ROM, bootloader, and recovery?
After upgrading did you re-flash a custom recovery and re-root?

Not yet. Gonna play with stock for awhile. I kind of like odexed and dont have a burning need to root. As for the "junk" in stock roms, there really isnt much, and what there is you can disable so not a big deal.

OK so just to clarify. I am currently on 1.27.531.11 rooted with a Unlocked S-off bootloader and TWRP recovery. All I need to do is, leave the bootloader unlocked and run the 1.27.531.11 RUU file. Once that is completed I can take the OTA to 4.3. Once this is complete will I still be S-Off and unlocked or S-off Locked? Then if I want to root (asuming bootloader is still unlocked) I would just need to flash the TWRP recovery and then flash SU, and I should then be updated to 4.3 rooted with a unlocked S-OFF bootloader. Is all of that correct? If not, please correct me before I attempt this. Thanks for any help.

Ok, I'm really curious about this. I want to quickly know what ROMs can be flashed to a phone that is HTC Dev Unlocked and S-On.
Currently running MeanROM 1.91 (and HTC Dev Unlocked & S-On), but I would really like to run Cyanogenmod on it.
I understand you can flash the radio in an S-On phone, but it has to be done in recovery, vs doing it in the bootloader with an S-Off phone.

You can flash whatever ROM you want, as long as you have a custom recovery.
And you can flash radios through recovery as long as your HBOOT isn't the one from the latest OTA (1.15). In that case, you can't.
You can. just backup, and do a full wipe, and and flash.

I think the only thing you gain with s-off is the ability to update your firmware.

I got my phone a week ago (actually on the 13th), and as soon as I got it, I let it do the updated to 1.22.
I have TWRP 2.2 as my recovery. HBoot is 1.15. In that case, is there any ability at all to update the radio to something newer?

Well, currently there isn't a newer radio, but if there was, you'd have to relock and take whatever the new OTA would be to upgrade your firmware (including radio).
Radios cannot be flashed through recovery with the new 1.15 HBOOT, nor can splash screens or kernels.

So, to relock, I would have to follow one of the threads on unrooting and relocking the phone? You can't do that by just re-flashing the stock ROM (its how it worked with my LG Optimus S and Motorola Photon 4G)?
The point is, I want to run CM9 or 10 once it becomes stable for this phone (when camera, MMS, and everything else works)

Actually, you don't have to re-lock to take an OTA, if you're on stock. But being as though you want to run a custom ROM, you'd have to nandroid backup your current setup. Relock the bootloader ("fastboot oem lock"), and then flash the latest RUU, at which point you'd be updated to the latest firmware.

I'm sure there will be.
So, the process would be:
1.) relock the bootloader
2.) flash the latest RUU
3.) unlock the bootloader, and re-root
4.) flash to the latest CM9/10 port (and install the latest gapps)
I'm interested in getting the latest OTA update and attempt to S-Off. I am currently unlocked via HTCDev, on the old GB firmware, and running CleanROM DE.
How do I go about doing this? I've searched the forum and attempted to relock for a couple of hours now with no success. Can someone please give me some instructions on what I need to do? From what I've read, it would be better to get the latest OTA before attempting S-Off. Is that right?
I am no expert, but I believe if you made a back up of the stock Rom, you could just restore it, then s-off. It would be easier to s-off, then you could ruu the newest update, and install a custom recovery after that. Like I said, I am no expert.

I didn't back up the stock ROM. How can I get back to stock so I can attempt S-Off?
Have you thought about following these directions?

They worked for me.
Those are the instructions I was following. It says you must be on a stock gingerbread ROM or the 3.14.605.5 ICS Leak niether of which i am on so I guess that was my issue. It would get stuck after the first reboot and tell me to check device manager for adb or hboot drivers. I'm fairly certain I have all the drivers installed so it must be the rom I'm on. Thats why I was trying to figure out how to get back to stock.

To RUU, you need to lock the bootloader first, you DO rename it to ph98img.zip and then flash in hboot.

Awesome, thanks. I actually have the stock, rooted version of the RUU downloaded and ready. (vigorOTAStockRooted.zip). I'm much more familiar with CWM than I am with Amnon RA. Just to confirm: All I need to do is rename the RUU to P98IMG.zip and reboot to recovery, correct?

I'm needing to take my phone into sprint because I believe my digitizer needs replaced. The screen keeps freezing and clicking random things without me touching it. Tried different roms and kernels do figured it must be hardware issue.
Anyhow I'm needing to keep my hboot s-off because my laptop craped out on me this week and wont be able to re root and s-off again without my laptop working.
All I'm wanting to do is make my phone look stock by putting a stock unrooted rom on it so sprint can replace the digitizer.I've looked on the web n can only find a stock rooted rom but where can I get a stock unrooted rom? Thanks

Easiest way is to flash the RUU.exe from Windows or the zip version of the RUU from the bootloader. That will return everything to stock including the bootloader and recovery, but leave you S-OFF so you can just flash a custom bootloader and recovery after they repair the phone and you will be back in business.

You'll need the .zip version from this post to do that. The one at the top is the latest (Sprint ICS 2.89.651.2).

When my digitizer went out, I took mine in rooted and they fixed it no questions asked. In fact, one tech asked me about my team custom splash screen I made and another loved the skin I was running.
But, I understand not wanting to give them any reason to argue.

Hello members,
Looking for some confirmation please as I am finding conflicting information on the forums.
I am currently running 4.1.2 (1.27.531.8). The phone is rooted and s-on (never saw a reason for s-off if anyone is curious) I am also running the ClockworkMod Recovery v6.0.3.2 and hboot 1.44
My phone currently sees the 1.27.531.11 update available, but fails to update. I'm guessing this is because I have a custom recovery installed.
What do I need to do to get to 4.3 (3.24.531.3)?
Do I need to flash stock recovery before I run the official update from HTC? Do I need to upgrade to 1.27.531.11 and then 3.24.531.11?
Most importantly, what happens if I run the official 4.3 update from HTC right now?
Thanks in advance,
Zx
Any insight?
Thanks,
Zx

If youre s-off you dont have to worry about flashing stock recovery and hboot.
edit: actually, Im incorrect. You can just run the RUU. Download to desktop, plug phone in while its on, and run RUU. It'll take about 10 mins. You'll then be unrooted stock.

you could try Sunshine to get S-OFF it cost $25 dollars but it can S-OFF your device.
But I think that you do not need to be s-off to run the RUU, if you want to easily relock the bootloader use tthe HTC One 2014 (M8) All-In-One Toolkit http://forum.xda-developers.com/showthread.php?t=2699065 its the easiest way

In short...No. First off, you can't install the 4.4.3 update if you have a TWRP recovery installed. You have to have the stock recovery in order to do the update. But...for the sake of argument, you did the update and...then re-rooted and restored your nandroid. You would in effect overwrite the update and put yourself back to where you started (if that makes any sense).
My advice would be to install a custom ROM that containes the 4.4.3 update already...or put a stock recovery back on your phone and do the update. There is a nice all-in-one update you can run right off the sdcard using Hboot. I did it and it was flawless.
Either way, you'll most likely be setting up your phone again but that really shouldn't be too bad. Take some screenshots so you will remember just how you had things.
Hope this helps and good luck.

My advice would be to install a custom ROM that containes the 4.4.3 update already...or put a stock recovery back on your phone and do the update. There is a nice all-in-one update you can run right off the sdcard using Hboot. I did it and it was flawless.
Either way, you'll most likely be setting up your phone again but that really shouldn't be too bad. Take some screenshots so you will remember just how you had things.
Hope this helps and good luck.
