Safe to RUU? - AT&T HTC One (M8)

I have searched but wanted to make sure that I am safe in specifically what I am doing. I have S-off, superCID, and modified stock ROM am I safe to flash the latest stock RUU from HTC?
Thank you very much in advance!

Please disregard this post. I've found the answer

If you find the answer, post the answer (answer your own question). Others may look to your thread with the same question.
If you are talking about the AT&T M8, and flashing the most recent RUU intended for this version, than yes its safe (with s-off, custom ROM, etc.). No need to relock bootloader to RUU, since you are s-off.
S-off and SuperCID will not change from RUU.
Just be sure to backup any data you want to keep, as RUU will wipe the phone.

[Q] jelly bean/root question

Hi guys
I am unrooted and I want to root s-off before I do the jb ota update. Let me know if I am in the right direction, in order to do this, I need to unlock/root s-off with dirty racun as my h-boot is 1.19. (dont necessarily want to flash a rom just yet). then I relock (still being s-off) do the ota, and then unlock again, and root? This is just what I have learned from reading info in the forums. thanks

Do not do it this way. You do not want the 2.09 h boot whether your are soff our not. Once you obtain soff ONLY FLASH RADIO FIRMWARE. I believe it's the first zip in captain throwback thread for the new firmware. Read before you do anything. There it's no need to ever change h boot. 2.09 gives problems even if u are soff.

Once you are S-OFF you don't have to take the OTA and the firmware you want is the file that does NOT include hboot,kernel,and stock recovery
On XHausX firmware thread it is the first file under firmware downloads and Capt_Throwback it's listed as Full firmware
Any questions shoot me a PM

[Q] Firmware/Software/radio

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?
Thank you again..

your CID if you have an AT&T HTC One is CWS_001
radio version can be found in about phone.

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.

You dont need s-off for RUU just use the ruu in the general att section of the m8 forums

And more reading, too.
OP is obviously unclear on the basic facts and steps, and needs to learn more before proceeding.
S-off is not needed to run RUU. RUU will install stock ROM. And why do you need to RUU in the first place?

RUUs and S-OFF

I have perused the forums of multiple HTC devices, trying to figure out if I can flash any RUU I want (that is compatible) to an HTC One M7 that is S-OFF. If I can, do I need to downgrade my HBOOT before applying these RUUs? Thanks to anyone who replies.

Assuming you have a M7 that is S-OFF and you want to run a M7 RUU of the same type of M7_U/UL then yes. You have to make sure that your CID & MID are compatible. If the hboot is lower than the phone then you will need to downgrade the hboot.
It would be easier if you would post what RUU and the fastboot getvar all except for imei and serialno of your phone. If you want a more definitive answer.
I was looking for a general answer, yours did the trick. Thank you!

How to root (with links) is explained on my thread here: http://forum.xda-developers.com/showthread.php?t=2751432
Also, much of the "HTC specific" lingo is explained here: http://forum.xda-developers.com/showthread.php?p=52484527
I would suggest reading up (and making sure you understand all the terms and processes) for at least a couple hours before trying anything on the phone. I do this every time I buy a new device, even having own quite a few HTC phones. In fact, I usually start reading and researching before I have the phone in hand.

also is there a way were i can go back to stock when i need to thanks

If your talking about ROM, then take a full backup of your ROM before flashing custom ROM using titanium/nandroid etc.
Or if your talking about root,
Just unroot using unroot apps from play store or the respected app you get after rooting.

As the above reply stated, it depends on what you are talking about.
If you just want the stock ROM, recovery, etc. one option is to relock the bootloader and just run the RUU. It will return you to stock software. The only thing not "stock" will be the bootloader will say RELOCKED instead of LOCKED. You need s-off to make it say LOCKED again (after unlocking it).

so this is what i want to do i want to unlock bootloader then root which i know how to do but i was woundering would i be able to install this rom http://forum.xda-developers.com/att-htc-one-m8/development/rom-sd-4-0-sense7-port-sdkernel-t3062367
would i be able to install that rom soon as i am done unlocking the bootloader and rooting or would i have extra stuff sorry for the dumb questions

You should be good to go, then. Just unlock the bootloader, install custom recovery and flash the Skydragon ROM you linked.
would i need to be s-off and would i be able to go back stock and relock the bootloader with s-on again sorry for the manny questions i am new to this phone

You can return to stock with a RELOCKED bootloader with s-on.
You do need s-off if you want to make the bootloader say LOCKED as it was from the factory. But the only reason to ever do this is for warranty purposes. And if you bought the phone from AT&T, you should note that your warranty is through AT&T, not HTC. And AT&T doesn't give a crap if the bootloader is unlocked, or whatever (folks have even successfully sent in phones for warranty with custom ROMs on them).
If you are seeing warranty service through HTC (you didn't purchase from AT&T) that is another story. But that is the only reason I'd bother going back to LOCKED.
In normal usage, I recommend leaving the bootloader UNLOCKED as it give you more flexibility to flash ROMs whenever you want, etc. The only reason IMO to relock the bootloader in normal usage is to run the RUU.
S-off is nice have if you want to flash radios, modified hboots, and some other things (you also don't need to relock to RUU with s-off). It certainly doesn't hurt, and some folks like to make the phone as customizable as possible right away. In fact, I did s-off to the phone the second day I had it (although s-off was free back then). But for you, its not strictly "needed" at this time unless you want to do the things mentioned.
so heres the thing again sorry for the manny questions i am just making sure if i do this everything will work so heres the thing the rom i linked if i were to flash it will my at&t sevice work since it would be a different baseband
can you link me the latest twrp recovery for the at&t htc m8 so i can flash once i unlock the boatloader

The baseband isn't determined by the ROM, its determined by flashing a different baseband/radio (which requires s-off).
There are some folks that have had issues on AT&T's LTE network using some custom ROMs. Namely, not receiving or sending voice calls while on LTE. But this seems somewhat random, and not the ROMs fault per se; but probably changes that AT&T is making to their network. The most you can do is flash the Skydragon ROM, and if you have problems, try another ROM or revert to stock.
Make a backup of your stock ROM with TWRP before you flash anything, to be sure you have something to revert to if you have problems. This is good general advice before you flash any custom ROMs, root mods, etc.
I'm using the ROM your linked (Skydragon Sense 7) on AT&T, and it works fine for me.
