I just bought a new at&t HTC One (M8) and I'd like to have a fresh stock backup in case of return/warranty problems. I'd like to make this myself so I can ensure that I'll be able to put the exact software that came with my phone back if need be. Also I'd just like to know how to do this in general. What I've found via search has been for rooted phones or different brands. Is it possible to use ADB or any other tool to do this? I guess I'm confused because I see posts for flashing back to stock. How do devs get these stock roms? If someone could point me to a good guide/tutorial it would be much appreciated.
Not without a rooted device or an unsecure [email protected] backup...there is an ruu posted for the 1.58.502.1, thats as close to being a backup without altering the phone in anyway
As long as you are a current account holder, AT&T does not give a crap what software is on your phone, bootloader unlocked, even a custom ROM installed in regards to warranty service based on many reports on XDA.
If you are still wondering about returning to stock, as mentioned in the above, your version (AT&T) if fortunate enough to have a 1.58 RUU. The ROM Update Utility is a useful means of installing a full stock image (ROM, radio, recovery, etc.) via connection to a PC.
But it can still be determined the bootloader is unlocked, no matter what you do to the phone to return it to stock. Your IMEI is tracked by HTCDev.com when you unlock the bootloader. But again, as long as you go through AT&T for warranty service (highly recommended for this reason) they don't care if the phone is modded.
I believe the stock ROMs you mention are system dumps done after bootloader unlock.

OK if I root this thing and install custom recovery, from my understanding we cant completely return it to stock, yet is that correct. We would need the RUU file to achieve this and restore the original recovery and we don't have it yet from what I can find or at least for the ATT version. There again if if root it and install CWM I can backup the stock rom and restore it if something happens this should also restore the stock kernel basically what are my chances of bricking this thing. Forgive me I haven't flashed kernels or roms since the original galaxy tab and Im a little rusty
NO!! You cannot return to stock if your device is from ATT caus official RUU for ATT not available anywhere on the net. Thats my problem too If you backup your rom with CWM you can only backup the system and data partition so recovery or any other is cant revert to original. If Jetstream gets S-OFF we can flash the rogers official RUU when something goes wrong and need to go back to stock. So I dont know why dont exist an official ATT RUU anywhere. Lot of people need it to go back to stock. I personally need to S-OFF to update my rom to Rogers caus ATT dont allow to update the Jetstream rom in the near future. ATT sucks to lock the ability of this device, updates, S-ON. They kill this device with this high security, no one buy this with this. People buy Samsung Tab or iPAD 2 rather then Jetstream caus iPad has Jailbreak and Samsung also has the ability to root, unlock bootloader and flash any rom you like easily. So hope developers can S-OFF the Jetstream.
From my understanding the s security goes off when you unlock the bootloader which can be done at htc developers. So with s off I can return to the Rodgers version and restore the stock recovery
Bootloader unlock and (Security Flag) S-OFF/S-ON is different thing. New HTC-s secured with 5 different Locks 1. Bootloader Lock 2. Security Flag 3. eMMC or Nand Lock 4. CID or Provider Lock 5. SIM Lock
When you unlock your bootloader, Security flag remains locked, S-ON. That is mine problem too.
Hope somebody can make the S-OFF. I can donate 25$ for it.
I recently unlocked my bootloader and rooted my phone. I installed TWRP and flashed a couple of custom roms ( GPE & Revolution HD ) I decided i want to go back to stock. I understand so far i gotta unroot, flash stock rom and re lock bootloader. I read something about RUU files. Any one have suggestion or help how i go about this? Again, i have AT&T varient, currently on Revolution HD Rom

There is currently no RUU available as of right now. I think the best you can do for now is to a TWRP restore. There is a stock rooted TWRP in the Android Dev forum. Although this won't un-root you, its closest to stock that you will get. For the future, always make a backup before you root and then you won't have to worry

I just ordered my device and still waiting on it to be delivered. I'm already debating on whether or not to root as I've never owned an android phone that i didn't root. From what i understand, the bootloader needs to be unlocked, then s-off, flash recovery and then root. Now, if i'm to do a nandroid of the stock ROM before I root, will I be able to lock the bootloader again, nandroid and s-on in case I need to utilize the warranty? Also, will any warranty bits show up or a tampered flag or any other problem arise that'll indicate it's been farked with? Is there a way to undo those flags? Thanks in advance to TheEmpyre or whomever else can shed some light on this.
EDIT: If the s-off is the only step that will trip the flag, is it possible to leave S, er, ON?

Unlocking the bootloader trips a flag. When you relock it gets rid of one flag but trips the relocked flag. Soff can get rid of all flags but you have to leave it soff. Turning it back on throws a security flag.

If you are current AT&T customer, and can go through them for warranty, they do not care in the least whether you are bootloader unlocked, rooted, s-off, etc.
I know AT&T written policy says otherwise (they have the right refuse warranty on modded phones) but in reality they cherish you paying that nice monthly bill every month over the modest cost of a refurb phone.
I've come over from the One X (EVITA) forum, and there were many (possibly dozens) of report from XDA users successfully returning their devices for warranty with bootloader RELOCKED, UNLOCKED, and in some cases even with custom ROMs installed! And I haven't seen any reports otherwise (AT&T denying warranty due to modded phone).
If you are not a current AT&T customer, and have to go through HTC, that is a different story.
But if you are an AT&T customer, my personal opinion is that you do not need to care about being able to return to stock, tripping flags, etc. Just mod away.

I can second this. I just had to replace my m8 because the speakers were crackling like crazy, my bootloader showed relocked and they told me straight up that they didn't care about that as long as it was a hardware problem and not a software problem and replaced it on the spot.
I was under the impression that if you were in your first year of owning the device that faulty hardware would be covered under HTC's factory warranty and not AT&T?

Looking at the return info, I can see where the confusion might come from. It says "Return directly to manufacturer" for 15 days or more:
http://www.att.com/shop/wireless/returnpolicy.html#fbid=KMGdewZyG_f
But AFAIK, all warranty returns go to AT&T when you work through their warranty department. You send them your defective phone, and they send you a refurb. I haven't had to go through this process myself, but this is what has been reported many times on XDA and other forums.
Any update on this how to lock bootloader for HTC M8 AT&T with 4.4.3 InsertCoin 4.1.1 Rom S-On of course.
How do I lock the bootloader in order to upgrade to stock 4.4.4?

No "update" on this issue is required. The process has been the same for a couple years or more. Further, you've posted the same/similar question to multiple places, and its been answered already in multiple places.
Connect phone to computer in fastboot mode.
Open command prompt, and type: fastboot OEM lock
From there, you can run the RUU.
if HTC allows downgrading the bootloader so I can install a custom rom after I make the mistake of taking an OTA update from ATT. With the S4 this wasn't possible. but since this is my first android phone, I was wondering if it was Samsung trying to keep the device "secure" or ATT forcing these companies to keep their bootloaders locked.

Once you unlock the boot loader no update can relock it. HTC offers a lot more freedom than samsung, but at the price of no warranty. So if you unlock it and shatter your screen, don't be upset like other people when htc will not warranty it. As long as you have a custom recovery, your phone cannot even physically take an ota update so nothing to worry about either way.
The Magnuson–Moss Warranty Act is in place for us consumers for this reason. The company has to prove that any modification you did, is the cause of the trouble. So if you unlock your bootloader, root, etc, then crack your screen, as the poster above mentioned, the company can not void your warranty since what you did has nothing to do with cracking your screen.
This was huge for me when I modified my car and I found this here on XDA after doing more searching

Oh and yeah,,if you are outside the US, it wont work lol

That depends on what you mean by "allow". You cannot downgrade the bootloader by any "official" means. You will fail version check when you try to install, as you can "normally" only flash a equal or great version number hboot.
But if you are s-off, version check is bypassed, and any hboot version can be flashed.
Similar to a previous response, my advice would be to unlock the bootloader (required if you want to flash custom ROMs anyway) and S-off the phone soon after you get it. Neither of those can be changed by any OTA.
Also, accepting OTA is not recommended on a modded phone, anyway. Whatever came in the update will usually get posted in a stock rooted form in the Development forum, and/or incorporated into custom ROMs, often within days of the OTA rolling out. And OTA will not install on a modded phone (stock recovery needs to be present). OTAs also may plug existing s-off or other exploit; preventing you from doing them if you haven't already (but as mentioned, can't make the phone s-on again). Moral of the story, I strongly recommend against OTA on any modded phone.
Some of these terms/concepts are HTC specific, so may be a bit confusing for you. I would suggest reading up on these forums, if you aren't familiar with s-off, HTC's bootloader unlock process, etc.
Got a stupid question and can't find the stupid question section on this forum for the M8 as in the M7 section. But, I have a new phone which I have upgraded to . I am not new to the rooting and switching roms I have done it since the One X, but , can I flash a custom recovery without unlocking the bootloader? Reason is , I use a app called Privacy Star for call blocking and just discovered by means of me having two identical phones except for the color . One has all the OTA's up to Android version 5.0.2 HTC Sense 6.0 the other is straight ouf the box and no updates, software Android 4.4.2 Sense 6.0. The app seems to work fine with 4.4.2 but the app makes the phone ringer silent after a blocked call and it has to be put in recovery and recovered or reboot the phone to get the ringer back. I know that flashing a custom recovery removes the ability to take OTA's and want to keep the phones at 4.4.2 , at least for a day or two. So can I flash a custom recovery such as TWRP without rooting? and RUU the one phone with the updates back to 4.4.2? Make sense? I hope so.

I think someone did a "stupid question" thread for this section at one point, long ago. But nobody really used it, it didn't get stickied, and quickly became buried among the other threads.
No, you can't install custom recovery without unlocking the bootloader. But you can restore to stock recovery when/if you want to install an OTA.
You can RUU back to 4.4.2 if you use sunshine ($25) to s-off the phone; which removes the version check, and allows you to "downgrade".

Thanks, wasn't sure and its been a long time since I have messed with a stock phone . I really didn't want to void the warranty just yet as the phone isn't much over 24 old so far and wanted to let it "settle" in before doing any mods on it.

If you want, since the phone has older software (4.4.2) you should be able to temp root and s-off with sunshine ($25) which can also unlock the bootloader without using HTCDev.com. And HTC will therefore not have a record of you unlocking the bootloader. And with s-off, all can be returned to full stock (LOCKED bootloader, s-on, etc.) so HTC would never be any the wiser.
But also note that if you purchased the phone through AT&T, modifying the phone by unlocking the bootloader (root, etc.) does not actually void your warranty. AT&T actually changed their warranty terms a year or 2 ago. The only thing that voids the warranty are physical damage and water damage. There have been numerous reports of folks that successfully got warranty service from AT&T with unlocked bootloaders. But that is just through AT&T. HTC is a whole other story.

One phone has 4.4.2 software and the other has 5.0.2 software, I didn't catch the newest one soon enough and my wife did the OTA without me knowing it. The only reason I wanted the older software was the fact the app I like has a glitch in it with the newer software update and it silences the ringer . The app works fine on the phone with the 4.4.2 software I just wanted to make sure it didn't update itself
How to upgrade ATT HTC ONE M7 without losing root
Hello all, I have an AT&T HTC ONE M7 that is currently running Android 4.4.2 with HTC Sense 6.0 (software # 5.03.651.3). I have rooted it with TWRP and SuperSU and need some guidance to update my phone without losing the root (or unroot/upgrade/re-root). Can't seem to find anything. I want to stick with the factory ROM ideally, but would be happy to take a look at any other that is comparable. Not looking for added capability, just want to get my phone up to date.
Thanks in advance!!

I'm not an expert on these things, so hopefully someone will correct me if I'm wrong, but isn't software # x.xx.651.x for Sprint devices? The AT&T factory software is x.xx.502.x. So either you don't have an AT&T version of the M7 or you're not running the factory ROM. It's definitely not the AT&T factory ROM.
But to answer you question, since you're already rooted with a custom recovery, there probably has been enough changes to the system that will prevent the OTA's from installing, even if you reflash stock recovery. And if you are in fact running the Sprint ROM while on the AT&T network, you probably wouldn't get the OTA's anyway. So in order to get the latest updates you'll need to flash a ROM clean. Since you want to stay factory stock, that means the RUU, which you can download directly from HTC. You'd definitely want to confirm which variant of the M7 you have and make sure you get the right RUU. Pretty sure the AT&T RUU won't flash to a Sprint branded device unless you're S-Off w/ Super CID. And there may be some other incompatibilities in this situation. You may want to look into custom roms at this point.
However, once the RUU is complete and the clean ROM is up and running, it's a simple process of flashing TWRP and installing SuperSU to root.
You'll then need to spend time setting up all your apps and customizing everything to your liking, so make sure to set aside a block of time to do that. And be sure to backup any personal files onto your computer before running the RUU. It will wipe the sdcard.
So, yes, as it turns out, my brain was not working correctly and I do indeed have a SPRINT M7, not an AT&T one. I'm not sure why I confused that. Regardless, thanks for the help, sounds like I can do what I need to do without any significant risks, minus the time involved.
Thanks.
