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.

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.

hi guys,
i have a EVO 3D GSM. i read some threads and i understood that, after root, we have the possibility to revert it back to stock rom and send it back in warranty only rooting it some ways (if possible).
The question is: i have HBOOT 1.49.0018. There is a rooting method that will allow me to revert to stock and use the warranty?
EDIT: for what i read, downgrading and using revolutionary i shouldn't have warranty problem, right?
rooting and warranty. . .
Hey there, I myself have Evo3D CDMA currently hboot 1.5 and unlocked through HTC method to flash custom roms and what not. What I believe (which might not help much) is that "un-rooting" is quite a bit more difficult especially if you have rooted through revolutionary/alphaRev. ADB cmd's and terminal codes... many many lines to hash out either on the device or through fastboot. What I suggest is read read read read, then read some more. When it comes to warranty I think im screwed just because "htc unlock method" and they have a token/device id and all that but you may be able to get by! GOOD LUCK.

Did you relock before you took it in ? Or did you take it as is? My phones been acting up and I'm on sprint . I'm just hesitant to take it in unlocked or even relocked because they can obviously see I had unlocked my bootloader.I'm still on stock rom just use things like set CPU and little things .. haven't flashed any roms yet . Kind of hoping to get a replacement with a 1.4 hboot as the evo3d I have now is 1.5 which I know its still possible to flash but I'm more comfortable through cwm than fastboot .

So I discovered a slight gap on certain edges of my One, which I got a week ago, and want to return it to AT&T for one that hopefully has no issues, but I've rooted, unlocked the bootloader, and flashed CM 10.1 on there. I searched through google and the forums here on XDA to find a method to relock the bootloader and go back to stock, but my search was fruitless. Apparently something called an RUU was needed? And according to the last post in this thread, that isn't available.
Is the RUU available now? Or is it currently impossible to relock the bootloader?
If so, would I be able to pull off just flashing the stock ROM back onto the phone and bringing it into AT&T? I feel like the only way they would realize something was different with the phone would be if they rebooted it, as I highly doubt most of the people in that store could even get into the bootloader screen. They had trouble syncing my google account.
Unless, of course, they send it back to the manufacturer and then THEY say that the warranty is voided because of the unlocked bootloader... but I don't know if they go through all that trouble in this situation?
Thanks for the help.

For a quick and easy way, just boot into fast boot and cmd "fastboot oem lock"
The only problem with that is that if they DO boot into the bootlaoder, it will say "RELOCKED" instead of "LOCKED"
The longer way, is to S-OFF (find it in the international forum) and then follow instructions there to put the "LOCKED" text back.

Get S-OFF, I was able to remove TAMPERED and change my UNLOCKED to LOCKED. You can also flash a modded HBoot that will take the red letters away and change the text from S-OFF to S-ON this will allow it to look like you never touched a thing
To get S-OFF I recommend http://forum.xda-developers.com/showthread.php?t=2314582
To mod your HBoot go through the post from here http://forum.xda-developers.com/showthread.php?t=2316726 (to download the HBOOT and here http://forum.xda-developers.com/showthread.php?t=1786498 to download the tool to create the modified HBOOT
But to let you know, I have returned 2 HTC Ones with unlocked bootloaders and AT&T did not say anything. Just flash the stock rom, make sure fastboot in enabled and leave it booted to the set up screen. Above is for if you want to be thorough and make sure you cover all your bases.
I wanted to return my HTC One to stock, and it took me hours to do so. I had to search for multiple threads, and it was a big hassle and pretty confusing. I am back to stock now, although I am still S-Off. I figured I would compile a thread helping others in similar situations return to stock. This guide will help you return to sense, lock your bootloader, unroot, hide your tampered banner, as well as prevent your device from showing up as relocked. You're device will still remain S-Off after following these steps.
Here are the steps. I am assuming the recovery is device specific, and I wouldn't recommend flashing the recovery.img on any device other than the AT&T M8.
1. Make sure your device is S-Off. If not, download firewater and S-Off your device.
2. Restore a nandroid of the stock Sense ROM, or find a stock ROM to flash. You'll have to dig around; I used a nandroid.
3. Flash SuperSU.zip in recovery on top of the stock Sense ROM. You can find the SuperSU.zip here: http://download.chainfire.eu/396/SuperSU
4. Use adb to flash the stock recovery.img to your device. You can get the recovery files here. http://forum.xda-developers.com/showthread.php?t=2711814 *ONLY FOR THE AT&T MODEL*
5. Boot back up into sense, and follow this guide to remove the tampered banner in recovery. http://forum.xda-developers.com/showthread.php?t=2708565
6. Follow this guide to lock your boot loader and make it say **LOCKED** instead of **RELOCKED**. http://forum.xda-developers.com/showthread.php?t=2708571
7. Boot your device back up, and open SuperSU. Go into settings and find the "full unroot" option and run that. Reboot your device like it suggests.
8. I would factory reset your device in settings or recovery to make sure everything's clean, although this step isn't necessary.
Enjoy Sense! Hope I was able to help some of you guys! ?

I am not sure. I haven't tried returning to AT&T. The only thing they can get you for is S-Off, but some devices shipped S-Off so I don't know how likely that is to happen. AT&T shouldn't look into it too much. They don't have access to HTCDev so they can't see you've requested an unlock token.

I don't know about your AT&T store reps, but I can't think of a single one from a store local to me that would have any clue whatsoever on how to determine if the device was rooted, unlocked, etc.
Also keep in mind that, unless you've personally irritated one of them, THEY (usually) DON'T CARE. They might be required to check certain things by AT&T corporate, but do you really think that a typical sales rep is going actually exert any extra effort whatsoever to check the device?
Take the steps you mentioned. Leave the device S-OFF, but clear the "tampered" flag (as you mentioned) and any type of red warning that happens on the boot animation. Basically, just fix up the extremely obvious stuff that a sales rep couldn't possible ignore. When you go to bring it back, act like you've never heard of "XDA", and if someone asks if the phone was modified, tell them that you changed the default ringtone or something silly like that. (In other words, play dumb.)

I was in a store the other day with a friend who needed something done to his account. Beside us was a rep trying to activate an M8 for a customer. She kept running to the back to get different SIM cards and couldn't figure out why they wouldn't fit. She was trying to put them in the SD card slot
And you're worried about them checking bootloader locks and S-Off? :laugh:
To give an example of how "closely" an AT&T store rep examines a phone for exchange/return:
I noticed a couple days ago that the volume button on my own M8 is quite a bit more.. wiggly.... than the AT&T demo M8's in my local store. It doesn't really bother me, but I figured I was still in my "14 days" so I could get a simple exchange for a more perfect volume button.
So, I spent about an hour backing up my device, changing the CID back to CWS__001, switching the firmware back to AT&T stock, switching the recovery back to stock, patching the bootloader to NOT show "unlocked" or "tampered", etc. Basically, when I was done, it was nearly impossible for even a knowledgeable person to know I had "converted" the phone to a dev edition and so on.
I brought the phone to the store and here's what they did to examine it: NOTHING.
They saw that the screen turned on, and that was it. Nothing else. I was extremely disappointed. (Perhaps it relates that I had just factory reset it, so it was sitting at that stupid AT&T welcome screen... perhaps they didn't want to waste time tapping through all the prompts?)
Oh, and I ended up NOT doing the exchange. They brought a new one up, and it had the same wiggly volume button. So, we opened a couple more boxes and all were wiggly. Being that I didn't see any other defect in my existing phone, I decided to keep my known wiggle instead of risking a different different that wiggled just as much, but might also have some other issue.

There was a poster who claimed they told him he was ineligible for the replacement because they had him on record on HTCdev as unlocking his boot loader. Said he needed the dev edition to be able to do that without voiding his warranty. That was just one person though
I got my device 2 days ago and rooted immediately. Then I noticed I was on the old firmware version, so I used your guide to get unroot and back to stock. It worked well. Now I'm updated and rooted again

Believe it or not all you have to do is put the stock rom back on the device. You still have a hardware warranty. If say, your speaker is broken that would have occurred regardless of you flashing the ROM. Flashing the rom is not a punishment for you to live with bad hardware... However try to put back to stock if you can.
thank u for helping

AT&T terms clearly state that they have the "right" to void warranty if the software is modified.
In reality, AT&T will not check or care. Its more important to keep you as a monthly account holder, versus the relatively modest price if a refurb phone. I've seen many reports of successful warranty exchanges with unlocked bootloader, root, even having an obviously custom ROM (like CM) installed.
Return to close as stock as possible/feasible to play it safe. But its likely not going to be a deal breaker.

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

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.

Got a stupid question and can't find the stupid question section on this forum for the M8 as in the M7 section.
can I flash a custom recovery without unlocking the bootloader? 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 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
