How do you Restore HTC ONE back to stock? - AT&T HTC One (M8)

Hi everyone I recently flashed a rom on my HTC one m8 for at&t (ViperOneM8_1.7.1 rom)
and I was wondering if anyone can point me in the right direction in terms of how to restore my phone back to
at&t stock?
I only have the bootloader unlocked and I have TWRP recovery. I didn't make a backup before I flashed the rom so I can't just restore back into stock.
Thank you for taking the time to read this if someone could at least point me in the right direction I would appreciate it.

The question I ask is "for what purpose?"
AT&T does not require the phone to be stock in order to fulfill the warranty.
If you simply want to return to the stock AT&T ROM, just flash the stock rooted ROM.
Only valid reason IMO to return to stock is to sell/trade the device.
If you are keeping the device, I don't see a good reason to return to stock. The stock AT&T ROM is gimped, bloated trash. And the same holds true for any OTAs that will be released. Unlocked bootloader, with root and a custom ROM is far superior.

Thank you GermanGuy for the links!
Yeah I want to be able to go back to stock for whenever I sell/trade the device. Also, I was thinking about cancelling my AT&T plan and migrating my phone over to a different carrier like straight talk. I haven't done that before so I don't know if switching to a different carrier becomes harder if I am on a custom rom.

The phone can never be returned to truly stock, in that once the bootloader is unlocked HTC will always have a record of that, linked to the phone's IMEI. Therefore, when selling or trading of the device, you should always disclose to potential buyers that the bootloader was unlocked. Although I agree even with this disclosure, some buyers may want the phone to be as stock as possible.
On some previous HTC devices, the SIM unlock code only worked on Sense based ROMs (but not AOSP) but it didn't matter if it was a custom or stock Sense ROM. I don't see any other reason why being on a custom ROM would affect you switching carriers. Its a smartphone, and works like any other regardless of whether its on a stock or custom ROM. In fact, being on a custom ROM may even make that experience easier, as custom ROMs tend to have multiple carrier APNs pre-configured; and also some features such as personal WiFi hotspot/tethering which are blocked by AT&T (without the proper data plan) are easier to get working on other carriers using a custom ROM.
In any case, the previously linked RUU is what you need to return to (close to) stock.

How do I flash to Verizon compatible ROM?

Currently I have a HTC Touch Pro with Sprint, the ROM has never been changed since I got it, I have modified many things about it but I have never gotten as deep as flashing ROM's. I'd like to do this without bricking my phone so I am sort of paranoid about being careful doing this.
Basically, I am canceling with Sprint and I want to change my ROM to work with the Verizon/Alltel network so I am able to activate it on the PagePlus network. I know there are many things to go through on this forum that probably answer my question.. but I don't know where to start.
Are there already instructions for this somewhere or could somebody give me some? Any help is appreciated.

You have to unlock your device before being able to flash a rom on it. The flashing and the transferring of the device to another carrier are two separate matters. If I were you (and considering that Verizon tech support are not the smartest, or the brightest), I would leave the device with the stock rom, take it to Verizon, have them add the device to their network, and then unlock and flash a new rom. I have a tutorial on how to flash to other roms (look in my signature), but do it only when you are ready.
Good luck!

[Q]at&t unocked vs international factory unlocked

I want to buy one m8. what is the difference between at&t factory unlocked and international factory unlocked version. can i flash roms in international version thread on at&t factory unlocked model directly??
Yes you can flash any rom you want from the international thread. I am currently running Android Revolution.
Sent from my unknown using XDA Premium 4 mobile app
The 3G and LTE band compatibility is different. Do you intend to use on the AT&T network? If so, the "international" (EMEA) version is compatible with AT&T's 3G bands (850 and 1900 MHz); but lacks both of the LTE bands used by AT&T (700 and 1700 MHz) according to this: http://www.gsmarena.com/htc_one_(m8)-6074.php
Not band compatibility is set in hardware, and cannot be changed by flashing different software (ROM, radio, etc.). This means the EMEA version cannot be used on AT&T's LTE network, not matter what you do.
If using on a carrier besides AT&T, I'd check the band compatibility with what your carrier uses. Even if the AT&T version is compatible (with you carrier), I'd probably recommend the international version over it (if compatible as well). The AT&T version is loaded with crappy AT&T bloat and limitations. For instance, WiFi hotspot is blocked, so bootloader needs to be unlocked and the phone rooted in order to make it work on other networks.
Plus, there is the ugly AT&T logo on the back.
Just thought i would bump this thread instead of making a new one. I bought an unlocked at&t htc one m8 off of ebay that i plan to use in another country (i study abroad). I already checked that the frequency bands are compatible, etc. Here's the thing, i don't want my phone to have anything to do with at&t other than the logo in the back. In other words, i want to make it as similar as posible (if not exactly the same) to the international unlocked version. Is this possible with just software changes, etc? (i've read the phones are the same in terms of hardware). I want to remove all at&t bloatware and limitations. can someone please give me quick explanations of what i need to do or point me in the right direction? I'm not new to xda or rooting, but the only smartphone i've ever had is a samsung vibrant (which i've rooted and flashed roms countless times).. this is my first htc phone, so im not very familiar with htcdev or s-off.. but i learn quickly.
I would really appreciate some help

I have the ViperOneM8 rom installed. What is even cool is in the tweeks, you can change the AT&T bootup and logoff screen to a viperone screen. And change the AT&T logo in the pull down menu to any picture you want. s-off isn't really needed unless you plan on changing the kernel.

What you describe is easy to do by just unlocking the bootloader, installing custom recovery, and flashing any international based stock rooted ROM or custom ROM. I basically have done the same, as even though AT&T is my carrier, I absolutely hate their branding, non-standard signal icons, bloatware, and limitations (particularly Wifi Hotspot/tethering).
As the previous user already suggested, learning and reading is the best thing for you to do. Don't proceed until you have a good understanding of the concepts and process. My Index thread (specific to the AT&T versions) is a good place to start up reading: http://forum.xda-developers.com/showthread.php?t=2751432
Great, thanks for the information and guidance guys. i'll definitely spend the next couple days reading before rooting the device, i can't afford to brick it. Any other tips or advices as to how to go about rooting, etc?
Developer build device and ATT device are same exact hardware, ONLY difference is ones sim locked and other isnt, bought 2 developer device from [email protected]'s both run fine on ATT networks...

If you look at my Index thread I linked above, the first item under "Unlock Bootloader, ROOT, S-Off" is an excellent step-by-step guide to rooting. There really isn't much I can't add, the guide is so thorough. But I'd still advise to read around and make sure you fully understand all the concepts and steps, and not just blindly follow the guide.
If the goal is to install a custom ROM, you can stop before the step in guide where it says to flash SuperSU (after flashing TWRP), and just put a ROM on the phone and flash in recovery similar to how you have done in the past. The guide is written with the intent of staying on the stock ROM and rooting.
One tip I can give, is that you may notice there are some Toolkits that attempt to automate some of the process (bootloader unlock, custom recovery, root, etc.). I would actually recommend avoiding the use of these. Reason being, the steps aren't actually all that hard to do "manually", plus these toolkits (while well meaning) shortcut the learning process, and rob you of a valuable learning opportunity.
I'm assuming OP doesn't want a custom ROM or root. Just to convert the AT&T branded model to a stock unlocked model, and still get OTA updates. This is possible. You need to unlock the bootloader, get S-OFF, and then follow this guide (you can skip step 1, changing MID): http://forum.xda-developers.com/htc-one-m8/general/change-wwe-m8-to-dev-edition-ota-t2826567

Yeah, I plan on doing it manually. Thanks for all the good advise man. I'm liking what I see in these forums, I'm glad I landed here.
Sorry it took me this long to reply guys, I have been very busy in the past week. Time to learn me some HTC one m8.

One last question guys, hopefully somebody can answer me. I've already read a few topics on the terminology used (s-off, ruu, htcdev, etc.), and things don't seem to be too far from what i thought they were. I'm ready to root and flash a custom rom, but here's my question:
I'm a very methodical person, i like to know what I'm doing and that it's the right way to do it. When i flashed a new rom (or rom version) on my samsung vibrant i would do a full wipe (factory reset, clear chache, clear dalvik cache, format system, and format data) before flashing, then i would flash the rom, and then i would flash the rom on top of itself without doing a full wipe. This method worked for me for over 3 years and kept me from getting common bugs some people complained about. Is it fine if i do this with my m8? (i mainly want to know if it can cause problems).. What's your common flash routine?
Thanks for the help guys
I am simple, I do what you do except the double flash.

What you've stated is fine. Although factory reset already wipes data, cache and Dalvik, so its a bit redundant.
I'm the opposite of methodical (at least in the way you describe). I like to get things done with as few steps as possible (while still doing it right). I've similarly been flashing ROMs on Android devices for 4 years (4 HTC devices and 2 Samsung). But I hardly ever wipe system (flashing a ROM does that by default) and never double flash, and I've never had any issues I would attribute to flashing methods.
Some folks will swear by wiping system for every ROM flash, but honestly while there is nothing wrong with it, I don't believe in it and almost never do it (unless sometimes where the ROM specifically says to do so in the instructions).
On the other hand, there is nothing wrong with redundancy, and if you like to be methodical and thorough I would say just keep doing what you have been doing.
Hi there,

Do fastboot getvar all, and post the results (delete IMEI and serial number before posting) and if we look at that info, we can probably determine what version it is.

[Q] confused about main firmware and rom bases

First of all this is my first post. Hello to everyone. I have been searching/reading thru these forums. Great source of info.
Phone info:
Currently S-OFF, unlocked, lateset AT&T 4.4.2 firmware, viperone 6.2.1, twrp
I have a pretty good comprehension of how to install or revert pretty much anything that can be done to this phone and have done so with great success. What I don't understand is the relationship between the firmware base of an RUU and the build of any given ROM. How is it that a custom Rom based off let's say x.xx.401.x work with x.xx.502.x main version? The devs say to update to the most current available firmware. Does that mean I have to flash a firmware base that matches what the Rom base for optimal performance? Because I originally thought that was the case and when I did my phone developed syncing issues particularly with the stock mail and weather apps. They would only sync over WiFi. Everything else about the phone worked as normal. Believing there was a problem with the Rom I flashed a few different popular roms on here. Always returning to full AT&T stock first. I later fully converted to GPE and to my surprise everything worked as normal. So I then converted to stock developer edition by way of zip flash and RUU exe. (By the way, when I say stock I mean s-off & unlocked but otherwise factory.) Received all the ota's. Main version would show as x.xx.1540.x. supposedly this would make my phone a dev edition with AT&T as the provider. And yet the syncing problems returned. So once again I returned back to factory AT&T 4.4.2 and all returned to normal. I then decided to try and use a Rom based off 4.4.2 and not one from 4.4.3; expecting the syncing issues to return only this time they didn't. So now I am really confused.
My questions are:
If coming from 4.4.2 factory firmware, is it best to run a Rom from the same base or am I doing something wrong and I should be able to use a Rom from a newer base on an older firmware?
If the developer edition and GPE can be carried by AT&T then why was I having syncing issues with the developer edition and not GPE?
I thought by being s-off I should be able to flash any RUU from any carrier without problems, just that I would be limited to the network capabilities of the actual service provider.
Everything I know about this stuff I learned from this forum. But I think I missed something.
My AT&T M7 always works best on the stock software.
The only thing I could figure is that AT&T have refined the software and radio so well that all the other versions pale in comparison.
I noticed the Developers Edition always had a horrible Bluetooth and WiFi radio. Signal strength was always weak compared to the stock AT&T software.
To answer your questions
Flash any version Roms you want on the latest AT&T firmware. And you'll have the best your phone can be.

I get so mixed up with all the terms being used interchangeably. So to clarify, as long as I am using the latest firmware from AT&T (currently 5.12.502.2 kk4.4.2), I can flash any custom ROM base. Whether it is based on 4.4.2 or higher. Correct?
I still want to know why I experienced the sync problems while running the factory x.xx.1540.x dev edition but not with the GPE. I never tried the factory x.xx.401.x WWE firmware either. However, I just got an sim unlock code from AT&T earlier today. I'm gonna try that maybe tomorrow and see if it makes a difference altho I don't believe it should. And I'm not gonna switch to a different provider.
Honestly, I was happy with my phone before I got wrapped up in all of this. I just decided to tinker with the phone and the mod bug has bitten.

I think I figured this out. I continued to flash different ROMs and firmwares with the same results as I posted in the OP. Then earlier tonight I decided to try to convert to developer edition again (x.xx.1540.x) and flashed an ruu.zip, went thru the setup process, and as before the same issues returned. Then I had an idea; lets try something I haven't done yet. I pulled the SD card and factory reset the phone. After I completed the basic setup process I inserted the SD card and let the phone do its thing. The phone now works as it should (same as it does with the AT&T xx.502.x firmware installed).
Just figured I would pass this along.
Cheers
I give up
I thought I had this figured out. Last night after to converting to dev edition with all updates, everything seemed normal. I flashed the latest viperone rom as it is the rom I want. Turn the phone on this morning and the sync problems are present once again. I have searched thru a tom of pages on this sight alone. I cant find an answer. So its back to stock at&t.
I solved the problem. Incorrect settings in 4636 menu.

[Q] Is it just me, or is everyone with S-on stuck?

I am fairly new to the whole ROM thing on this device. I have experience with older phones and am just getting back into this recently. That being said...
Current state is: Bootloader unlocked, currently running stock 4.4.4, Sense 6.0, Kernel 3.4.0-g931e842, Build 3.42.502.1 CL441323; ROM applied via RUU. (RUU_M8_[email protected]41216A_40.34.C35006.02_F_release_407726_signed_2)
Bottom line is that since I have attempted to root and flash ROMs I have had issues with making and/or receiving calls, or no SIM recognized at all, requiring S-off/firmware upgrades, etc.
I am looking for a stable build ROM which is compatible with the 4.4.4 firmware on my device which can be applied without obtaining s-off. Main goal is to be able to personalize the UI and to run a faster, debloated ROM.
Tried first using Renovate 5.0... could not receive calls on that one.
Removed. back to stock.
Next I found a Lollipop 5.0.1 ROM (HTC_One_M8_Lollipop_5.0.1LRX22C) which did not appear to require firmware updates... seemed to work great... except that I could not receive calls...
Removed... back to stock.
Next, I used ViperOneM8 and really liked it, but had to abandon once I was told by people that they were still getting sent straight to voice mail.
I did get some calls, so I tested having some people call me and it seemed fine... well turned out that during those tests I was on the 3G network... Once again, troubleshot down to the fact that anytime I was on 4G network I could not receive calls. Having had no way to change my network selection in this ROM (error was displayed when I attempted this). Contacted their support to confirm my issue. They are aware, no resolution available.
Removed... back to stock.
So my question is, are there any options OTHER THAN paying $25 to use Sunshine to get S-off, upgrade firmware? I am not a developer and I love my M8. I know there are people here who know exactly what I need and understand what I am looking for. Thanks in advance for any assistance.

I can't tell what ROM your are talking about based on that description. Possibly GPE stock rooted?
What I can tell you, is that most any Lollipop Sense ROM will have issues when used alongside 4.4.4 firmware.
Sense 4.4.4 ROMs will play well with your firmware, as will a number of 4.4.4 and 5.0 GPE and AOSP ROMs (that specifically state they support 4.4.4 firmware). However, when it comes to AT&T, there is more at play then whether the ROM corresponds to the firmware. That other complication is that AT&T does some annoyingly unique things with their network. In the past, this has included changes to build.prop and even the signal icons, which sometimes caused "international" custom ROMs to have some issues. And now you see that their HD Voice (Voice over LTE) is messing with some custom ROMs. As the other thread you posted in mentioned "blame AT&T".
Running an AT&T base 4.4.4 ROM is your best bet for trouble-free use on AT&T's network. WNC's ROM might fit the bill for what you want (debloated) and is often where I send folks that want a bug-free experience on AT&T (while retaining some AT&T specific features). The 3.28 version ROM is what you should try: http://forum.xda-developers.com/att-htc-one-m8/development/att-4-4-3-2-22-1540-3-debloated-sense-6-t2837365
There are other ROMs that might work for you. But the above is my suggestion, at least as a start.

You are correct. It is a GPE stock rooted Lollipop ROM. It works just fine as long as I have 3G selected as my network, but it is just not as much flash as I wanted.
I am going to give the one you sited here a look and maybe give it a try. I appreciate your taking the time to reply. It was helpful and informative.
Erring on the Side of Caution
I'm in a similar quandry as the OP. I have lots of experience flashing ROMS on my older phones but trying to keep up with all the changes since getting my M8 has me confused.
Here's my current setup. I'm running Skydragon after trying the last 4.4 milestone of Liquidsmooth. I like both, but am interested in keeping up with the Lollipop guild.
I have Sunshine installed but when I ran it I found out I need to remove or disable Xposed Installer to continue. I'll deal with that by disabling it.
UPDATE: Well, that didn't work. Xposed was installed with the ROM and there's no option to uninstall it.
My biggest concern is updating the firmware. From my bootloader info, I'm assuming that I'm way behind on the latest firmware, but after reading so many threads about updating, my head is swimming.
If I need to update, I just want to make sure that I don't brick my phone.

Return to stock ROM and stock recovery, for optimal configuration for sunshine to work. RUU is probably the easiest way to get back to stock. Backup your personal data, than relock bootloader to run RUU.

Yes, based on your hboot number, your firmware is about as old as it gets (Android 4.4.2).
You can RUU to 4.4.4 firmware without s-off; and Lollipop Skydragon GPE should work fine with 4.4.4 firmware.
You can of course still s-off and update to Lollipop firmware. But you need to use some other firmware besides AT&T (such as Dev Edition, Euro, etc.), since they haven't released a Lollipop update (and therefore no firmware).

Custom ROMS with Cricket and Lollipop kernel questions

Hi all,
Sorry if this has been posted before but I haven't been able to find my answer by searching.
I am considering an S5 and am hoping to be able to run custom ROMs and have a real recovery. I would like to get service with Cricket as they are significantly cheaper than ATT or TMOB. Will ROMs work across carriers, or do they have carrier-specific code?
Also, I am hoping to run a vanilla Lollipop ROM, do these use a custom kernel or are they based on stock? I have always had issues with non-stock based kernels and tend to go for 'GPE' type ROMS.
Thanks!

If you want an AOSP ROM for the S5 you must buy one that isn't the G900A. The ATT one has a locked bootloader and can not run a custom kernel. The only option you have is a touchwiz rom on the G900A. If you get the tmobile one you can use whatever you like I believe.

I'm sorry, originally I put G900T in the title, thought I had specified that. I definitely don't want an AT&T phone unless I go with an active. Hoping to find out if the vanilla lollipop kernels for this phone are stock or not and if any/all custom roms are able to be used on Cricket with a simple SIM swap or if there is another procedure for it.

Buy a T-mobile one, then you can run whatever you want. Make sure you get it SIM unlocked so your Cricket SIM will work. As for Carriers, there is no difference what SIM you have in there. It will still work.

I'll ask a mod to move this to the tmobile forum for you. I think they may be more helpful. We are strictly touchwiz here on the G900A whether we like it or not sadly.
Thread moved to T-Mobile Q&A forum as this is what the OP is looking for.
