How to rollback from Oreo to 7.1? - HTC U11 Questions & Answers

Hello, I just installed Oreo but don't like it and am looking to rollback to the most recent Nougat update on my U11. I have not flashed an Android device before. I have looked at these guides:
https://forum.xda-developers.com/u11/how-to/guide-htc-u11-how-to-return-to-stock-t3628452
https://forum.xda-developers.com/showpost.php?p=72831916&postcount=3
Though I don't quite understand them. I have download the 1.27.401.11 firmware for EMEA from the spreadsheet (since my device was bought unlocked and I put a Three SIM in it), and also the adb installer. How do I go about using these to install the older firmware?

I believe the first step is going s- off then flashing the appropriate nougot ruu if available. Just my 2 cents hopefully others will chime in. Hth

You must flash ruu correct cid for comeback nougat.

If you upgraded to Oreo via ota
I don't think you can go back to nougot without going s- off, at least not from what I read.

I am sorry because i am answer not clearly.
I was s-off for change supercid for update oreo.
I was s-off again and flash ruu for rollback from oreo to nougat.

You can do it without S-Off. I did it last week... BUT, you must do it with same CID/MID for it to work.
The guide is located here.

please be mindful that you will need to remove spaces for it to work... I think it should look like this from memory
Code:
adb shell "dd if=/dev/block/sde1 bs=1 skip=2208 count=16"
I also don't recommend it if you dont know what you are doing...

I have a question. Can this be done with super cid? Or must the cid and mid match the ruu?

Okay so I found my MID (2PZC10000), do I need to unlock my bootloader before doing anything else?

If you're supercid, you have s-off so you can do whatever you like... Read the other thread about downgrading.

No idea,,, My bootloader is unlocked.

I have installed ADB and verified it works with 'adb devices'. How do I go about loading the .zip Nougat file to modify it in the command prompt? Also I assume the 'TWRP Flash' button on the TWRP app restarts the device into Download mode? Lastly, once the commands to modify the RUU have been executed, how do I actually install it to the U11?

Supercid is no longer valid. Your cid must match one in the list of cids that the firmware is compatible with or it won't flash.
If you are dirty flashing you can expect bricks. You are best going the s-off route rather than forcing the firmware on. At this moment in time the U11 is a very expensive paperweight.

My CID and MID match the firmware from the spreadsheet so I should be fine, what is dirty flashing?

[HOWTO] [HTC One SV] Unbrand your phone to get the OTA updates

Bonjour everyone, here's a little guide on how to unbrand your phone in order to get the OTA updates notifications directly and be able to install them.
If you want to get S-OFF one day on your One SV, read this first. You need to change CID to SuperCID to do so, and it's not possible (for the moment) if you upgrade to JB
Basically this works as long as your phone model is sold unbranded somewhere in the world and that the people having such a phone got an OTA update.
For now, ther's no way to change CID if you're running JB and are S-ON. That means that this only work for One SV's running ICS who want to get the OTA updates.
As far as I know, it works on K2_U and K2_UL, since they both got an OTA update to JB.
The trick is simple, I didn't invent it and haven't been able to find its original founder, but thanks a lot to her or him !
I'm basically just a messenger here since I only tried out some stuff that worked with other phones, so thanks a lot to bkcokota, old.splatterhand and jmztaylor
Don't try it if you're worried, bricks happen, you'd be the only one responsible !
Here we go :
1. First you need to root your phone, here's how.
2. Change you CID using the same method than for the One S.
Personnaly, I changed it to "HTC__203", which is the CID unbranded HTC phones have in France (HTC-FRA).
For example, "HTC__001" is HTC-WWE, which stands for World Wide English.
You can change it to whatever CID you like : choose it well. I can only recommend to use HTC__203 since it's the only one I tried and that it worked, but do as you please !
3. Flash stock recovery back. You'll find it here or here. Flash it like you flashed CWM recovery (into fastboot, using fastboot flash recovery xxxxxx.img).
4. Relock your bootloader. It's possible that it's not necessary, but it can't hurt ("fastboot oem lock", when in fastboot usb)
5. Run a RUU that matches you unbranded CID to get an "unbranded" rom.
You'll find them here, for example. The "RUU_K2_UL_ICS_40_HTC_Europe_1.17.401.5_R....exe" one will work with HTC__203 and HTC__001 CIDs.
6. Go ask your phone if he can find any updates
WARNING : for the moment there's no way to change CID if you upgrade to JB since the newer HBOOT (v2.00) don't let you do it. That means that for now you won't be able to S-OFF if you upgrate to JB using this method. For now...
Nice one!
Only thing i would add for people to know:
if somebody want to get S-Off, they should change the CID to SuperCID 11111111 (or if you want 22222222,...).

Done, sir.
It was only said at the bottom of the message at first, but now I put it at the beginning as well.
There's one thing that I'm trying to get though : according to a lot of people and forums, you don't get OTA when you have SuperCID... but some poeple say they do.
It probably changes depending on the type of HTC phone, but also depending on the OTA (some got the first ones, but not the latest...).
I got the ota notification with SuperCID, i think it depends on more things.
But there i'm not far enough into it.
I have had no success at all. My story:
Updated a branded phone to JB, rooted. Then I did a moonshine S-off and changed CID to HTC__001 (even tried 11111111).
I have downloaded a ICS RUU (couldn't find stock K2_UL so I thought that I would download ICS first and then do OTA to JB) but I am getting error 158. I have checked md5 sum and it matches (http://androidfiles.org/ruu/getdown...0.14_2_10.49.40.11L_release_301902_signed.exe). Any ideas?
If you're on jb and hboot 2.00, that's normal... and written in the first post.
There is information that it is impossible to change CID while on JB and with 2.0 hboot, but I guess that I have had success in changing to superCID (at least this is what I can read in bootloader and using fastboot oem readcid command.
So, as far as I understand newer hboot won't let me use older RUU as well, right?
Is there any chance to make this for the k2cl ( boost mobile ) version?

To get it a bit clearer.
At this point i'm not very up to date, thats why i didn't answer til now.
I think (but i'm not sure) you can flash the ruu, if you are on hboot 1.0.
And as you are S-Off you should be able to downgrade hboot. But this is a very risky point, you can easily brick your device. Here is, how you have to do:

To change hboot you will need a PL80IMG.zip on sdcard with android-info.txt and hboot.img inside it.
reboot to bootloader and flash.
Click to expand...

The thing what makes it difficult, is to get the hboot.img (its inside ics ruu), cause the htc ruu's encrypted and i only have heard about tools for linux which can decrypt it.
Thanks to your reply I did some research and I have managed to do what I wanted. I have downgraded hboot first (by extracting and encrypting ICS RUU using linux), then I could run RUU and now I am stock ICS with S-off and superCID
Should I post some files from RUU? 1.0 hboot or stock recovery? You guys need something?
Thanks for your helping hand old.splatterhand!

Yes, of course, everything is appreciated! You can use this thread, please post ruu name too. You can look at my posts there. Hboot, boot.img, recovery, radio, would be fine.

Wow, that's cool !
Did you use rollon's method and flashed PL80IMG.zip in bootloader mode ?
If yes, which android-info.txt did you use ?
If not, how did you do it ?

Did you get the ota update notification for JB then ?
Did you manage to apply it ?
Thanks and congratulations !
Hi everyone.
Just a quick message to confirm that rollon's method works.
To downgrade you need to be S-OFF, extract and decrypt (with ruuveal, using linux or a linux virtualbox runned in windows) hboot and androidinfo from ICS RUU, put them in a zip named PL80IMG.zip, put it on your sd card and boot into bootloader. Then you can run the ICS RUU normally and you'll be back to stock ICS, with a "*** LOCKED ***" bootloader (not relocked !), will be able to go back to S-ON using "fastboot oem writesecureflag 3" (thanks to JMZ)...
You'll then have a locked S-ON out of box phone running 100% stock ICS with original boot, recovery and all that... who'll get the 2 JB OTA's...
In case anyone's interested

Firmware Update Q&A [extra noob friendly]

WARNING*WARNING*WARNING
do this at your own risk! This is for s4 only!!
It has been brought to my attention that there might be a mid (model id) conflict
With flashing this and me along with others are trying to narrow down the issue. Thanks to @real187 for bring this to my attention.
I'm
S-off
Cid 11111111
MID PJ4011000
And had no problems flashing this firmware but others with same setup have reported soft brick.
OK I think @mkinney88 may have pin pointed where the soft brick may be coming from. If you s-off using facepalm, flash the firmware.zip and get soft bricked try this.
1. Get back to s-on (warning read directions several times before doing you CAN hard brick your phone) ~ http://forum.xda-developers.com/showthread.php?p=38267667
2. Get s-off with moonshine ~ http://forum.xda-developers.com/showthread.php?p=42613403
First off this is mostly ment for the T-Mobile branded phones but ill try and help all please let me know when asking questions if you have a T-Mobile or HTC branded phone (it has it right on the front of phone ).
I'm starting this thread to have a place for noobs and long time users to ask and answer questions. This is going to be as noob friendly as possible but please keep questions firmware related only. So lets get started.
i really dont know how to make it any clearer then @mkinney88 did in his rom OP. all credit goes to him these institutions.

--> Unlock your device
Step1. download and use this program to unlock your bootloader http://forum.xda-developers.com/show....php?t=1604677
Step2. SuperCID your phone so you can S-OFF and so you can also write the T-MOB010 CID if you are on a different carrier and want to run this ROM. You will need to be CID T-MOB010 if you want to run the firmware.zip Follow this to SuperCID http://forum.xda-developers.com/show...1#post26516911
Step3. After you have sucessfully unlocked your bootloader and SuperCID you can either S-OFF your phone or Not, it is up to you. I would recommend you achieve S-OFF so you can flash radios, kernels, and boot.img's. Follow this to achieve S-OFF http://forum.xda-developers.com/show....php?t=2155135
If everything went well you should be able to reboot into bootloader using the All In One Tool and in the top left your bootloader should say Unlocked, S-OFF, CID-1111111
--> Writing T-MOB010 CID
If you did everything right then your all set. Next you will want to run the fastboot command " fastboot oem writecid T-MOB010 " and reboot into bootloader again. Now in the top left it should say CID-T-MOB010. If you have made it this far you are doing great. Now we are going to run the firmware.zip package to ensure everything works without a problem.
--> Flashing the firmware.zip
Now if you are coming from STOCK OEM LOCKED T-MOBILE PHONE that already has Andorid 4.1.1 Jelly Bean on it then you do not need to do this step. You must be CID T-MOB010 to flash this or S-OFF CID 11111111 (I had no problem flashing firmware with s-off and Cid 11111111 but others have reported problems so if you don't want to chance it write your Cid to T-MOB010)
1. fastboot oem lock
2. fastboot erase cache
3. fastboot oem rebootRUU
4. fastboot flash zip firmware.zip, and you might get an error
5. fastboot flash zip firmware.zip again and it should pass and install a bunch of files should take about 2 minutes.
6. the phone does NOT reboot on its own so #7
7. fastboot reboot or fastboot reboot-bootloader
--> UNLOCKING BOOTLOADER AGAIN
Now we need to unlock the bootloader again so just do step 1 again but you will already have the Unlock_code.bin from the first time you unlocked you phone so no need to get another one from HTC but if for some funny reason it doesn't work you will need to just resubmit for a new one.
--> CUSTOM RECOVERY
After doing all the above steps you will need to install the custom recover. You will need to use TWRP 2.3.3 to insure no problems. Here is the link to download it http://techerrata.com/file/twrp2/vil....3.0-ville.img after you download it go to the DIR where you have the HTC One S All-In-One Toolkit v3.5 extracted. example: C:\Users\yourusername\Downloads\One_S_All-In-One_Kit_v3.5\One_S_All-In-One_Kit_v3.5\Data\Recoveries and in the Recoveries folder rename the downloaded twrp2.3.3.img to TWRPS4.img and replace the one that is in the folder and then proceed to install the recovery,
now youve followed that and now your stuck ether getting errors or phone is now acting all erratic? that's why you're here. go ahead ask any question you want about firmware noobish,dumb,anything as long as its firmware related. (sorry i cant tell you how to get the cute girl at the mall)
this is just a crude start ill add and refine as we get going.
please do don't ask firmware questions in development threads ask here.

Bricks
First off if you can get into bootloader then you don't have a hard brick.
If your phone is in the black screen of death there may be hope but we're still trying to figure that one out.
If your phone doesn't respond to any input from you (power, power+volume down) then congratulations you have a hard brick but don't through it in the junk drawer just yet, you can have it jtag repaired (they open phone plug into main board and flash everything)

Bricks can't be recovered (unless you jtag) , you had a soft brick.
I had no problem doing this with s-off and Cid 11111111.
But I remember you from other threads and I have a few questions.
1. Is your phone t-mobile branded or htc? 2. When you first did the firmware update what was your hboot version?

Yeah mine was a softbrick. If you stroll over, u can find many people in my queue. May be it is happening only for people who got S-OFF with the Facepalm way. I was on Hboot 1.14 and so a T Mob branded one.
Also you will see a warning in Facepalm thread that flashing firmware on SuperCID phones likey causes a brick.

I'm on Stock JB 4.1.1 and my CID is BM___001, rooted, unlocked BL.
There is no RUU for this CID and only a JB OTA, The radio version and software version match with those of the phone.
my question is: Without S-OFF and SuperCID, Can I use the OTA.zip to be flashed for getting stock ROM? e.g if I am on CM 10.1 and I want to revert back to stock, can I use the OTA.zip?

I'm not sure if I understand your question. So let me ask a few questions.
What hboot are you on?
What carrier are you using?
Are you wanting to try cm 10.1 and afraid for losing stock?
What is stock just HTC sense 4+ or is there carrier added stuff?

OK since your on hboot 2.15 there's no need to upgrade firmware.
Since there is no RUU for stock the next best thing would to to make a back-up of stock using a custom recovery I would recommend twrp 2.3.3 (if you need help with this just ask that's what this thread is for)
Then I would copy the back up to your pc for safe keeping (you might even want to back it up on a cloud too I'd recommend goggle drive or Dropbox)

Thanks for the reply, really much appreciated.
I already have rooted the device and custom recovery TWRP 2.5. Though I am considering to downgrade it to 2.3.30. Now I made a backup of stock ROM. (System + Boot Partition)
So is this the only way I can get to stock?
I read somewhere that the following method could be used too(?)
S-OFF ---> Run an older RUU for Bell Mobility (probably ICS RUU) ---> Then update OTA.
Is this valid?

Yes, if an older RUU is available for your CID just get S-OFF first then use it. Then you'll be able to update via OTA.

Yeah mine was a softbrick. If you stroll over, u can find many people in my queue. May be it is happening only for people who got S-OFF with the Facepalm way. I was on Hboot 1.14 and so a T Mob branded one.
Also you will see a warning in Facepalm thread that flashing firmware on SuperCID phones likey causes a brick.

This is very interesting to me because I have a unbranded one s from a small spinoff of T-mo in Iowa. I got s-off with facepalm and SuperCID at the same time, then on hboot 1.13. Now recently I upgraded hboot to 2.15 with a euro RUU, soft bricked but was able to recover with only a firmware flash. (details are a bit fuzzy right now) I didn't relock the bootloader, but did install stock recovery. Ever after this stunt I've had tons of problems with radio disconnects. I first thought my problem was hardware, but I just got it back from a very good repair shop and the same thing. Although better on a different carrier, I suspect only because the better carrier has stronger signal.

[Q] Installing RUU, which one to choose

Hi,
My battery has been acting up for almost half a year now and my usage time is half of what it was when i got it. I have been installing several different ROMs and kernels so I am at a lost on what's wrong. So I have decided to install a RUU to see if a total reset can fix my phone.
I found this page: http://www.androidfiles.org/ruu/?developer=Ville
Does anybody know which RUU from the link is the newest/best? Will I get updates from HTC when I do this?
Currently running trickdroid 10.3.2, bricked kernel, twrp 2.3.3, S-OFF and superCID - is there anything in particular I should know before doing this?
I have never installed a RUU before, hope somebody can help
anyone? Or perhaps just a part answer

Choose RUU according to your CID.
Must restore original CID to avaoid having problems with OTA updates.
If you receive OTA updates with superCID, a brick is going to welcome you.

Ok so i am in a similar fix.
I obtained S-Off/superCID the very next day i got my One S .. things were running smooth on stock. Looked out for some ROMS and finally installed one. Now I want to revert to my stock ROM while maintaining S-off/root. My problem is only that i don't find this ROM stable or the kernel .. just want to revert to stock.
Live in Pakistan, hence i doubt OTA is going to ever cause me any trouble. Could you please recommend which RRU should i install?
Would really appreciate some help from a fellow countryman

Yes, you're right. Latest 4.2.2 Custom ROMs are having some bugs at the moment.
I need to know some details before I recommend anything.
1. S3/S4 version processor? (CPU-Z from play store will tell you that)
2. CID & MID (CID getter from play store will tell you that)
3. Last Stock firmware you had/installed?
4. HBOOT version?

Okay that's good but I need to know the original CID that the phone was shipped with.
Also, I'll need to know MID (Model ID). You can find it out via CID GETTER. When you open the app search for the line [ro.aa.modelid]: PJxxxxxxx that's the model ID

Ok. I deem this RUU to be the most suitable for you, which is Here.
Just run the RUU and it will do the job for you.
A word or two of caution here:
1. The RUU will erase everything.
2. After the RUU, you might want to change your CID back to HTC__001 because it has been rumored that HTC will release JellyBean 4.2.2 + Sense 5 for the One S. If you update the ONE S via OTA with SUPERCID, you will brick your device.
And anyway, SuperCID is not necessary at all for flashing Custom ROMs.
3. You will lose the Root for sure. But you can flash custom recovery + SuperSU again after going stock.
Edit: Oh! and match the MD5 hash of the downloaded file and the one on the server. MD5 checking utility is on XDA somewhere.
Edit 2: The CID in all cases comprises of 8 characters. i.e HTC__001 (8 chars), BM___001 (8 chars, my CID) etc. So when changing the CID, be sure to have an 8 character CID.
regards

Will follow your instructions. I was following a guide (All in one tool kit for ONE S) to achieve S-OFF for rooting and following that procedure the CID was reset as well. Not sure whether i can achieve S-OFF without meddling with the CID .... This being my first HTC after SGS and SGS2.

For all I have read, the reason for going after S-Off to begin with is essentially to gain capability to flash customer roms. I feel sorry for being a consistent bother, but could you please guide me towards a thread where I can learn rooting without messing with S-Off ...

haha... Yes..
Well the All-in-One-Toolkit by Hasoon2000 is the one you have to follow. But no S-OFFing/SuperCID.
You just need the bootloader unlocked to get Rooted/Custom ROM/Recovery.
Since you have already unlocked the bootloader, I think it's not necessary to use the AIO toolkit again.
What we need is this:
- Run the RUU. (Run it first, and if it gives you errors, you might need to Relock your bootloader which is quite simple).
[For the latter part] - Then if you want to Root you stock ROM, we will have to flash custom Recovery, which again is quite simple and can be flashed from fastboot. I'll guide you on this part later when you are stock again. No biggy.

AOA Orak,
I installed the RUU and am back to stock now. Using the toolkit installed TWRP S4 recovery but when i try to go into recovery a red triangle with an exclamation mark appears; the phone stays with it for a while and then reboots to normal desktop. Tried it a number of times with the same result. Since i am unable to go into recovery, i cannot flash the supersu.zip and thus no root :/ Should I go for CWM?

Ok so i figured it out in the meanwhile .. I had locked the bootloader before running the RUU. Unlocked it, installed recovery and flashed SU successfully.
So now I have two questions:
1- Do i need to re-lock the bootloader? If yes, will I still be able to flash custom roms?
2- How do i revert my original CID value? Will 'fastboot writecid HTC__001' do the trick? Are there any pre-requisites for it?

- Okay before anything, i would advise to flash TWRP 2.3.3.0 recovery and you will avoid many issues currently being faced with 2.5.0.0.
You can find 2.3.3.0 Here.
If you need help on flashing, ask away.
- now your questions:
1. No and No
2. You have to boot into bootloader and then go into FASTBOOT and write the command
fastboot oem writecid HTC__001
BTW, I assume you have adb+fastboot files on your PC?

[Q] A quick Q about Evita.

Hi there guys,
Not sure if any of y'all remember way-back-when, but at one point my AT&T One X went into (what seemed like) a bricked state. For 8 months, I didn't touch it, charge it, yada-yada-yada. About 2 weeks ago I decided to give it a go so I charged it for a half hour and the mo'fo' decided to work. I updated my ViperXL ROM to 4.2.0 because I enjoyed it for its features. Now I'm left to ask the question, do I have to update HBOOT to flash a JB 4.3 ROM? I'm still unsure because I feel like I remembered seeing somewhere that your HBOOT has to be a newer version to run 4.3.
Thanks and regards, worldindo1.
NOTE: My current HBOOT version is reading "1.14.002".
Yes you do need to upgrade, it's written in the install instructions for the ROMs. It isn't just the hboot you need to update though, you need to run an RUU to make sure everything gets updated.

Hey timmaaa,
So just relock bootloader, RUU file, and then unlock it again? Do you know of anyone who has just the firmware upgrade files from the RUU so I can do it from my Linux laptop? Thanks a ton, now I know I wouldn't have any problems or possibly brick my device haha.
Regards, worldindo1.
You need Windows to run an RUU properly, so you'll need to hit up friend to use their PC. You don't need to relock the bootloader as long as you get s-off first so I suggest getting s-off, it's pretty important because s-on + SuperCID + jb RUU = brick.

Howdy,
I am S-Off thankfully haha. I used XFactor back when it was still current. But I thought the main purpose of an RUU was to execute:
Code:
fastboot oem rebootRUU
fastboot flash zip (firmware).zip
Back when I had done some work with the HTC One V, we used unruu (for Linux) or on the Windows side, explored the RUU's %temp% folder to get the firmware files. Could I still issue those commands safely or have they changed how the RUU works? As well, since I'm S-Off, do I just issue all of the usual commands (minus the "fastboot oem lock") or ? Just making sure to do all of my homework before I jump in haha.
Regards, worldindo1.
Hang on, as far as I know Xfactor was a bootloader unlock exploit, that doesn't give you s-off. There's only one s-off method for our phone and that's the Facepalm method. Having an unlocked bootloader and having s-off are completely different. Can you please post your bootloader details?
Using unruu and pulling the RUU apart and flashing the firmware files is never how an RUU was supposed to be run, nor will it ever be. That's only doing a tiny portion of the job that actually running an RUU properly does. An RUU is an exe file which is meant to be run as an exe file, there is no other way to run it properly other than that. You connect your phone in fastboot mode and run the RUU in Windows and follow the prompts. Like I said though I really need to see your bootloader details (the first four lines) because I'm concerned you have s-off and bootloader unlock confused.

Converting AT&T carrier unlocked HTC One A9 from stock 1.27.502.5 to Nougat

Hey All,
Apologies if this is obvious but I couldn't figure it out myself looking at the FAQ's etc.
I just purchased a new HTC One A9 which was carrier unlocked by AT&T, and I want to convert from the RUU version they use (1.27.502.5) to the latest version that HTC has released on their website - 2.18.617.10 .
However, when I go to do this using that RUU, I get signature error 132. My phone is bootloader locked and S-ON, but from reading a little, I thought that shouldn't matter because I have a US phone, and you only need to change the CID/MID stuff (whatever those are) if you're in a different region?
How would I go about doing this? From reading through a bunch of posts, do I first need to switch to an unlocked version of Marshmallow, before then upgrading to Nougat?
Edit: Upon further reading, does the fact that the 502 in my current version does not match 617 in the one I wish to upgrade to mean that I can't do this with S-on? Do I need S-off? If so, how do I do that? Is it only by purchasing sunshine?
Thank you for your time!

In order to convert to another carrier version, you must change your CID and MID to match the RUU version you want to flash. .617 uses the same MID as .502 so you'll need to change your CID only from CWS__001 to BS_US001. Changing CID does requires S-OFF (Sunshine is the best way unless you know someone with a XTC2Clip box).
You'll also need to update your firmware to Nougat before flashing the Nougat RUU because of the signature change implemented in Nougat.

Okay thanks so much Two more quick questions.
1) Does changing to S-off have any consequences in terms of a future update? I'm guessing it will void my warranty, but say I wanted to go back to using AT&T's version of android. Would the fact that my phone is now S-off prevent me from using their RUU (assuming I change the CID back.) I guess my question is, warranty aside, is there really any negative to turning S-off?
2) This is more out of curiosity. HTC One Phones that were sold unlocked/developer that are currently running Marshmallow can be upgraded to Nougat without flashing the firmware to 2.xx.xxx.x right? So if I was to change my current CID to that of a developer One A9, and install that Marshamallow RUU say (1.57.617.60), why wouldn't I be able to simply update from within the OS as they do?
Thanks again for your time.

You would simply have to revert your CID back to CWS__001 and flash the at&t ruu. Changing the cid is easily done.
I guess my question is, warranty aside, is there really any negative to turning S-off?

S-off gives you full control and access to all partitions which mean there is no more mechanism preventing you to flash incompatible software/firmware on your phone. Once s-off, be sure to understand what you're doing before flashing files. The risk is limited if you'll only be converting to another version or flashing custom roms but if you're going to explore a little deeper yeah it can be dangerous.
2) This is more out of curiosity. HTC One Phones that were sold unlocked/developer that are currently running Marshmallow can be upgraded to Nougat without flashing the firmware to 2.xx.xxx.x right? So if I was to change my current CID to that of a developer One A9, and install that Marshamallow RUU say (1.57.617.60), why wouldn't I be able to simply update from within the OS as they do?

All A9 can simply be updated from the OS, not only the unlocked/dev version. The reason why you need to flash the firmware first before flashing a RUU is that HTC changed their encryption signature in Nougat. That mean your phone need the new decryption key to be able to flash Nougat RUU. Flashing the firmware first will update your phone with the new key, making it able to flash Nougat RUU.
There is a firmware.zip file inside ota updates. When you install an ota update from the OS, the first thing that is flashed on your phone is that firmware.zip. So no you don't need to manually flash the firmware because it's done automatically in the ota process.
Yes you could flash the 1.57.617.30 ruu and do the ota update after. It's just faster to flash the Nougat firmware first and the Nougat RUU instead of flashing the Marshmallow RUU and downloading + installing 2 ota udpates, well that's my opinion. Both methods will give the same result.

No, after converting to another version, you'll receive ota updates for that version.
Yes an no. There's always the possibility to revert back to your original version and hide everything you've done.

Edit2: I figured out the problem. I had to boot into the bootloader and then run
Code:
htc_fastboot oem rebootRUU
before I could run the RUU sucessfully. Am leaving the rest of this post up just so that other people googling this have a touch point.
Okay so I've used Sunshine to turn s-off and unlock my bootloader. I then changed my CID to BS_US001.
I then tried to install the HTC version of Marshmallow (maybe silly, but heard people having issues with Nougat and the battery) using the RUU.exe file. It started successfully, but then halfway though, after it had transferred the ROM over, it threw an ERROR155 and aborted, leaving my phone with an empty progress bar, and that circular green arrow icon in the middle. I used the command line to restart my device and had to factory wipe it, but otherwise not the worse for wear.
I tried googling it; do I need to relock my bootloader for the RUU.exe files to work? I think the Sunshine FAQ recommended against doing that. Is this a risky step?
Edit: Here are some instructions I found from the HTC One M8 firmware flashing thread. My error says "unknown" but I imagine its similar.
For “Error 155 relock bootloader" do:
- Since my thread works only with S-OFF phones anyway, this error can be read as: you need to S-OFF first!
- Error 155 can mean that you need SuperCID. On a few occasions this was shown when the RUU/FUU refused to run because of a wrong region lock.
- Lately, Error 155 has occurred when a FUU was launched from within android. When encountering a FUU error 155 with the process stalling after the rebootRUU (stuck at black screen with silver HTC logo), please just restart the FUU and leave the phone in that mode, or reboot the phone, then reboot to bootloader, then do “htc_fastboot oem rebootRUU” and then launch the FUU again (thanks @anarchychris for pointing it out).
- run the fastboot command “htc_fastboot oem lock" - only applies to S-ON phones that want to update the firmware with a stock OTA package (not offered on this thread!!). Stock OTA files sometimes need a locked bootloader.

AT&T conversion

In order to convert to another carrier version, you must change your CID and MID to match the RUU version you want to flash. .617 uses the same MID as .502 so you'll need to change your CID only from CWS__001 to BS_US001. Changing CID does requires S-OFF (Sunshine is the best way unless you know someone with a XTC2Clip box).
You'll also need to update your firmware to Nougat before flashing the Nougat RUU because of the signature change implemented in Nougat.

How do I get started to do this. How do I find out my mid Cid and if I need to change? How do I flash firmware first? I have android 6.0 software 1.27.502.5. I have done a run before but never changed from a carrier. I went to the link above but I don't know what some if this means and where to start and what steps to take in order.
