I am new to HTC as a whole. And I'm sorry if I'm missing something here. I've been spending my time reading the past couple of days trying to learn about this all.
It is mentioned but I never found a good explanation of CID and how it is relevant to anything that I have control over?
I'm currently running Trickdroid and I don't understand all of this 1.29 talk. From what I'm gathering from reading you can flash the Rom but it will not update things like the radio? Ok, How do I check my firmware/radio? version I am currently running?
Specifically am I reading beginning of dev posts and don't need to worry about this anymore because you wonderful devs have found a way to incorporate all this in just flashing a Rom?
Feeling a little overwhelmed coming from a Samsung device to all of this. So far so good, but confused and any help would be greatly appreciated..
Thank you in advance.

Radio aka baseband is almost never included in a ROM.
CID is carrier ID and every phone HTC makes has one. CID is what prevents you from installing say a UK carrier's official RUU on your At&T device.
HTC also utilizes something called SuperCID which is a carrier ID of 111111111 which allows you to install any firmware on your device. The only way at this time to get superCID is to gain S-off which is a security measure that restricts which parts of the phone software you can change.
With the HTC One, HTC changed what you have access to with an unlocked bootloader, previously, even with an unlocked bootloader you couldn't flash a kernel or a radio via recovery, now you can flash insecure kernels and HTC signed (approved) radios.
For flashing purposes, you can ignore the firmware requirements and flash the ROMs in the international section without issues.

Ok. Thank you for that explanation. How do I check what radio/baseband I am currently using? RUU, though it can still not be changed because we have no s_off, what is it? I
Also how do I find out what CID I am?

Ok would this be considered up to date? Why would I need to lock the bootloader again in order to update the firmware if I can just flash a Rom and it updates it for me?

you are up to date, and there's no need to relock the bootloader and revert to stock for an update UNLESS HTC releases a new HBOOT (the bootloader) and the developers here will let you know if and when that's necessry

One last question as it seems you would know. Is there a thread on the s-off process and how that is coming? Or is that just background dev?
I'm sure it's being worked on by someone.
I have an HTC One M8 AT&T Branded but it has 4.4.2 on it and i wanna flash viperrom 3.2.1 but it requires androids 4.4.4 software. im S-ON, 3.16 Bootloader with 1.58.502.1 Software number. Baseband Version is 1.16.21331931.LA11G_20.31A.4145.02L. im just looking to Update from 4.4.2 to 4.4.4 but i cant seem to find out how. Any help would be great.
Perfect.
Unlock your bootlooader if you haven't already, fastboot flash recovery (TWRP/PHILZ),root using the chosen custom recovery,make a backup before or after root.
Go here http://theroot.ninja/ for Sunshine
S-OFF cause that's what your going to need to update as far as 4.4.4
Orrrr just wait a few days for the ATT 4.4.4 build to be released (ETA 29th) and then youll have 4.4.4 without having to do anything.

That's a better idea for sure.
I haven't noticed if Sunshine has an update that works with 4.4.4 yet.
Are you S-OFF ?
What are the advantages/disadvantages of S-OFF so the OP knows what he might be missing.
Do you know when the Sunshine update will be?
Yup,no [email protected],[email protected],there are plenty of posts about advantages and disadvantages...my point of view is simple,it is not needed for the novice,ive seen too many mess things due to lack of knowledge. My usage of it is for switching between att and developer ROM's to get latest updates. Outside of that I dont mess with conversions,to risky for a 6-700 device. My advice is stick to htc dev unlocked bootloader and wait for official update.

I didn't Google for to long but I haven't found concrete links that state the exact date .how many times have we been promised a date and watch it pass by anyways.
May I ask if you've modified any other device before this one?
I'm not trying to push,but S-OFF might be in your future and will not halt an OTA from installing.
The version your on is easily exploitable using "Sunshine" unless you take the soon to be 4.4.4 update.
Nobody knows when Sunshine will have an update even with the team working on it as we speak.
Wont be much on Google @date,came from somewhere else. And nothing is ever "concrete" with software,especially with carrier branded software.

I have Rooted, and flashed multiple ROMS to my old M7 before. Nothing crazy.
I as well have the same build, unlocked bootloader, flashed custom recovery. Will I have to return to stock recovery using 1.58.502.1 RUU and to get the OTA update to 4.4.4??
I'm trying to get the latest Android Revolution ROM for 4.4.4 but realized I was in a bit of a pickle. I'd like to take the path of least resistance on this one - any advice would be super appreciated. Thanks!

I'd say wait till tomorrow to see if an OTA update will roll out.
Or if you just can't wait for the ability to flash what you desire than I would go S-OFF and flash a non At&t firmware that you need to allow a smooth function of mentioned ROM.
Im restoring back to default AT&T ROM and such and will post weather the update has been pushed or not. i sure hope it has

You can check as many times as you like by setting your time manually ahead and your phone/device won't know the difference.

So if you don't have s-off you can't update to 4.44 Sense ROMS with AT&T? I'm on Slim Rom and sound quality stinks. I want the new Android Revolution but i've read wi-fi and such doesn't work. Clarification plz?

Correct .
S-OFF allows you to change your CID witch will allow you to ruu Dev Edition 4.4.4 so everything runs smoothly
I've not looked on this thread in a while. I am S-off and unlocked and my cid is 11111111 but I have never updated firmware so that I can run a 4.4.4 rom. Is it correct that I flash a RUU (guess it's not called flashing when it comes to a RUU). How do I know which RUU to post - I found this one here: http://forum.xda-developers.com/showthread.php?t=2757462 (http://dl3.htc.com/application/RUU_...G_20.31A.4145.02L_release_368350_signed_2.exe)
Will I loose root or anything (other than wiping my data) when running the ruu.

I'll just say that if it's a stock ruu than it's most likely without root and it will wipe as if it came out of the box.if its a full ruu than it will come with the updated firmware as well witch should allow you to flash 4.4.4 Roms and still run smoothly.
What I did around 5:00am this morning was restore my Dev edition backup I had along with the stock recovery so I could take the Dev edition lollipop official update and now I have lollipop firmware to use with my stock GPE 5.0.1 lollipop ROM/backup .

Yes, running/flashing the 4.4.4 Dev Edition RUU will update you to that appropriate firmware. But, what you linked is not Dev Edition, its a stock AT&T RUU. And its not 4.4.4 either, its 4.4.2, which is probably where you already are.
What you want is the 3.28.1540 RUU linked here: http://forum.xda-developers.com/htc-one-m8/development/ruu-m8-developer-edition-sense-1-54-t2884777
RUU will wipe the phone, install stock ROM (meaning root will be lost) and stock recovery.
But I also think its overkill to run an RUU just to update firmware, if that is the intent. My suggestion is to just run the firmware linked in the following post (which also has great instructions for doing so): http://forum.xda-developers.com/att-htc-one-m8/development/att-4-4-3-2-22-1540-3-debloated-sense-6-t2837365
The above method shouldn't overwrite the current ROM and user data. But backup anything important before flashing firmware, just in case.
Side note, "flash" is a fairly generic term, and as the RUU flashes stock ROM among other things, the term "flash" is appropriate IMO.
So can I just load the firmware file and flash thru fastboot? Is it This one?

I can't make sense of your post so I can't help you. Maybe you could reword what your trying to do because firmware has nothing to do with a stock ROM.
basically i installed a new custom rom ARHD and my wifi doesnt work there. After searching on the web apparently it's a firmware problem. I was told that if i install a stock rom and update the firmware there and reinstall the ARHD again my wifi will work.

OK so you need the latest firmware are you S-Off? If so You need to download your device latest firmware an fastboot it. I would try that before I reflashed ROM..if you still don't have WiFi then I would a restore a stock backup you should have made or go to the development section an find an flash a stock rom

No, for the AT&T version that actually will not work. OTA will only update you to 4.4.4, and current ARHD is 5.0 (assume current Lollipop based ARHD is what you want).
Further, if you update to 4.4.4 OTA, this will break sunshine, and you won't be able to get s-off. So you will be essentially stuck on 4.4.4 firmware until AT&T releases Lollipop.
If you want to run Lollipop now (and any current ROM based on it, like ARHD) my advice is to s-off now. Then update to LP firmware manually.

I have 4.4.4 and don't know the firmware number (because of the known bug in a previous version of TWRP).
You've probably described why I can't get S-Off with Sunshine to flash the latest AT&T rom so I can know my firmware number.
I need to know it so I can flash stock backup & recovery and then viper.
Any recommendations? My thanks in advance!

Look at your hboot number in bootloader.
3.16 = 1.x software (Android 4.4.2)
3.17 = 2.x (4.4.3)
3.19 = 3.x (4.4.4)
Lollipop (Android 5.0) also uses hboot 3.19. But as already mentioned, AT&T hasn't released an offiicial LP update yet. So this can't be the case for you.

If you are hboot 3.19, sunshine won't work. Any earlier hboot, and it should work. If you updated to 4.4.4 by official means (OTA or RUU) then you have hboot 3.19, and sunshine won't work.

I don't understand what you hope to accomplish by flashing stock back and recovery. Neither will affect your firmware.
If you want to run any Lollipop based ROM (including current Viper) you need to update firmware, and on the AT&T device that means you need s-off. At least until AT&T releases LP officially.
So no, what you suggested won't work.

You're missing a key step(s): its restore stock ROM and stock recovery for the purpose of then updating via OTA. Reason for this, is that the OTA will update your firmware (for most carriers, that means updating firmware to Lollipop).
This won't work for you (having the AT&T version), since you appear to already be on the most current AT&T OTA (4.4.4). That means you are on KitKat firmware, but need Lollipop firmware to run any LP based Sense ROMs.
Also note that the page you linked is outdated, as it refers to 4.4.4, since that was what ViperOne was based on at the time (but its been updated to LP for a while now).
I have just read that sunshine has been updated to work on 4.4.4. I think this has literally happened just on the last day or so. So your options are to sunshine s-off and update your firmware. Or else wait for AT&T to release LP, and update by official OTA or RUU.

Redpoint, thanks! As posted on the other site, the new Sunshine option worked perfectly - I now have S-Off. Very, very cool.
So I'm on to your option one - update firmware so I can get viper on the device. Is there a recommended firmware update? How would I find this myself the next time?

The "right" firmware is a tricky question. I'd start with the 4.16.1540 firmware posted along with the ROM here: http://forum.xda-developers.com/att-htc-one-m8/development/att-4-4-3-2-22-1540-3-debloated-sense-6-t2837365
This is US Dev Edition firmware, which is specifically intended for AT&T's network.
Now whether it plays well with Viper or ARHD, is another question. Or whether those ROMs play well on AT&T's network is also another complicated question. AT&T does some annoyingly unique things to their network, that doesn't always play well with the "international" based ROMs. In particular, AT&T's LTE seems to be playing havoc on some "international" ROMs; possibly due to AT&T beginning implementation of HD Voice (Voice over LTE or VoLTE).
Trial and error is the best you can do. Start with the 1540 firmware I suggested, and your desired ROM, and see how it goes. But WiFi will be fixed, I can tell you that.
Also, the ROM included on the link I provided is intended specifically for use on AT&T (one of the few current ROMs that is). So if you want a LP ROM that will work seamlessly on AT&T's network, flash WNC's ROM and the 1540 firmware.

Perfect, that's all helpful and good to know.
For full disclosure: I'm on T-Mobile; it's the same network, I believe, so that probably doesn't change anything, but I mention it just in case.
So the process I'm planning to do it:
1.) Flash the ATT_4_16_1540_8_M8_Lollipop_Firmware and ROM
http://goo.gl/iumj9r
2.) Flash the latest Viper ROM.
3.) If it gives me trouble, flash firmware & from 1., above, to go back to that.
Does that sound right?
Also, do people restore s-on when they have their desired setup, or just leave the phone S-off?

T-Mobile and AT&T are not even remotely the same network. I know for a fact, the 1540 firmware I previously suggested (thinking you were on AT&T) does not include the AWS band that T-Mobile most commonly uses for 3G. And T-Mobile uses some different bands for LTE than AT&T.
T-Mobile has deployed 1900 MHz 3G band in select markets, in hopes of luring AT&T users (without having to swap devices). But only in certain cities.
Its best you flash T-Mobile firmware, for use on T-Mobile's network.

Typically, no. In fact, if you ever want to s-off again, I believe you have to pay the $25 for sunshine again.
For the most part, there is no real downside to staying s-off, in my opinion. Just be careful that you only flash anything meant specifically for the M8 (and the GSM version, at that, nothing for the CDMA). As s-off means many checks are bypassed, and you can accidentally flash something meant for another device that bricks the phone, if you are careless. But always be careful about what you flash, and staying s-off is fine.

Understood. Is there a similar link to recommended firmware for T-Mobile?
And then the main thing - is the process I suggest right? 1.) Flash new LP firmware; 2.) Flash the latest viper ROM; 3.) If I have trouble with viper that I can't solve, flash a ROM made for T-Mobile. Does that sound right? If so, i just need to determine the best firmware choice... and what are criteria might I use for that?

I can't actually find the Lollipop T-Mobile US firmware at first glance. The firmware collection is below (with instructions how to flash). But if you go to the firmware collection link (531 folder under HTC M8 is for T-Mobile) it only has 3.x firmware (Android 4.4.4):
http://forum.xda-developers.com/showthread.php?t=2696282
I'll look some more, but you can search as well.
Now, if I understand you have the AT&T version (please confirm)? If so, flashing T-Mobile firmware (once we find it) is a little more complicated than flashing AT&T firmware on an AT&T device. You will need to change your CID and MID to T-Mobile's, in order to flash the T-Mobile firmware.
The following guide shows how to change the CID and MID. But you will need to find the T-Mobile US CID. I don't know if off hand (or where to find it quickly), so you might do your own research on that one. Keeping in mind that T-Mobile is also a carrier in Europe, so make sure is the T-Mobile US CID.

I don't think T-Mobile is nearly as troublesome as AT&T (although you might check the T-Mobile M8 forum section on that, or the Viper thread). I have a feeling that once you are on the T-Mobile firmware, and flash Viper, you will be fine.

Confirming: I am using T-Mobile as the carrier, but the device was made for AT&T.
Is this what we're looking for? http://www.htc.com/us/support/htc-one-m8-t-mobile/news/
And, if so... as I'm S-off, I don't need to go through the stock ROM/stock recovery steps, and there's also no need to re-lock, RIGHT? I'd like to be as sure as possible that I'm doing the right steps in the right order.

You are correct. RUU will give you a complete stock T-Mobile image, not just the firmware you want, but also stock T-Mobile Lollipop ROM, stock recovery, etc. Its a bit of a nuclear option, if the main intent is to just update firmware and install Viper. But it will get the job done.
Also correct that there is no need to relock bootloader to RUU, since you are s-off. But you need to change to T-Mobile CID and MID to run the RUU.
What you will have after changing CID/MID and running the T-Mobile RUU is essentially a T-Mobile M8, in everything except the stupid AT&T logo on back of the phone!
If you want to install a custom ROM after that, just flash TWRP back onto the phone, and flash the desired ROM.

OK... so I think this makes sense. Is this the process, then?
1.) I change to T-Mobile CID and MID
2.) Then... to run the RUU, do I need to be in fastboot? Just have the phone plugged in? Run it from the fastboot directory? Put it in the phone memory?
I'd be running THIS, I gather: RUU_M8_[email protected]41216A_40.34.C35006.02_F_release_407726_signed_2.exe
Wait... that can't be right, given that the name includes "ATT" and "Cingular". I suppose they mean I have to find it myself... here? http://www.htc.com/us/support/htc-one-t-mobile/news/ Yes, the download at the end of this page, right? And it won't brick the phone so long as I'm S-off...
...does that seem right?
3.) Then I flash VIPER over that. If I have any problems with VIPER, I should be able to run this RUU again? Is that the best approach, do you think?
---------- Post added at 12:36 AM ---------- Previous post was at 12:24 AM ----------
Two additional things:
First, HTC (not surprisingly) refuses to say whether the RUU will work, even with S-off.
Second, a note from the chat, which I post for common interest here:
ME: T-Mobile and AT&T are the same, physically, right? Only SOFTWARE differences, right? Not hardware differences, right?
HTC Agent: Almost everything is the same. But the frequencies of the antenna are different.Don't know whether this affects our process here, but thought it might be interesting.
Also, after the RUU I'd be S-Off, but locked? Unlock again? Not that that should be difficult...

1) Correct
2) Normally, you just have the phone booted; and the RUU will reboot the phone to fastboot automatically. There are a few instances where some folk have to put the phone into fastboot mode manually. But it will normally work the way the instructions tell you.
Run the RUU executable from your PC. It doesn't matter where the file is located.
Use the RUU linked at the bottom of the HTC support page for the T-Mobile version.
3) After RUU, you will need to flash TWRP again; as RUU write stock recovery over whatever was there before (TWRP in your case). After flashing TWRP, then you can flash Viper.
Yes, if Viper give you trouble you can always use the RUU again.

They won't say that the T-Mobile RUU will run on the AT&T version, if that is what you asked them. HTC doesn't want you "converting" the device from one carrier version to another; since it contrary to what the carriers want.
Similarly, they won't want to acknowledge s-off since they don't like the mod community hacking/exploiting s-off in the first place.

I think that agent is simply wrong here. Snapdragon 801, band support is software based, for all but CDMA bands (which require different hardware).
If you search the forums, I'm pretty certain there are other users on these forums that have done exactly what you are proposing: converting the AT&T version to T-Mobile. I may have even helped one or 2 users do it.
