How to reset completely to stock? - T-Mobile HTC One (M9)

So Im no noob to android nor the rom/rooting crap. But i come from nexus devices and we all know how super simple those are to use and return to stock. I dont understand the HTC crap. I bought this m9 and thought it was going to be dev friendly like nexus's are but I was wrong. This is what I did. Unlocked bootloader, flashed TWRP (and before I made the backup, I set it to r/w) then i made a stock backup that was set on R/W and did some other things like flashing CM etc.. My question is, if i wanted to return to stock and be able to receive OTAs, what must I do. Would downloading a stock nandroid from here be enough or must I run an RUU(which i dont understand). Also, I still have S-ON and have not modified that. If read some guides but Im still confused. Nothing like a nexus. Any help would be appreciated. Thanks (tmobile USA)

Your best bet is to run the RUU exe from your pc, its very simple and takes about 10 min. It wipes everything and put you back to 100% stock.
it will not change your unlocked bootloader or S-on/S-off. keep in mind since you are S-on you can only use the RUU for the current version that is on your phone, you cant go back to earlier version
you can get the RUU's here
also the get OTA you have to be unrooted, and have stock recovery
Hope this helps

So, if I S-off I can run an RUU for any version, even the newest? And as long as I have stock recovery/unrooted I will be able to get OTA? Its that easy? Thanks for the help

I would like to. I installed ARHD 51 but it made my phone feel laggy and i also had reception issues. Had to put in my APN settings and even then my phone would pretty much stay on 3G and not go to LTE. i used my nandroid backup and reverted back. I wondered if i had to upgrade my firmware but that seems like a whole other issue to me. i don't know which firmware and some say to relock the bootloader while others say it's not necessary...just so confused.
maybe i'm making this more difficult than it is but as i've said, i'm a newb and really don't want to mess my phone up.

I know what you mean, but that's the great thing about having nandroid backup, if you end up with something that you don't like you can always go back. Have a try of the rom in my signature, or the sinless sense rom. Both are 4.2.2 and run exceptionally well for me.
I would recommend staying unlocked, though others will probably suggest you relock, ruu etc.

[Q] S-off with rooted HTC One M7 - HBOOT 1.57 S-on

Hello!
I've decided I want to turn my HTC One (International version) into a Google Play edition. I've watched a bunch of videos, and went for it. Everything went fine until the step where I should get S-off. I've tried quite a few tools, but just get an error that my version is not going to get S-off.
I have seen people been able to work around using CM11, but from what I've understood, you need S-off to write anything to /boot, which is where I presume CM11 would be flashed. So, am I missing anything important? Is there a workaround if my phone has HBOOT 1.57, and not S-off already? I hope someone can help me!
TL;DR: My phone is unlocked and rooted, but I can't get S-off using any of the most popular tools. My HBOOT is version 1.57.
I hope someone smarter than me is able to help me! If you need more information, please leave a reply and I'll get all the information I'm able to.
In advance, thanks!

No, you can flash cm11 with s-on. You have to have a custom recovery with which to do it, though. I don't know which tutorial you're using, but it should have a section where you flash the recovery after the bootloader is unlocked. If your bootloader is still locked, then... Are you rooted?
I'm pretty new to HTC, I just came off of samsung, and they seem straightforward and simple by comparison, but with s-off, it seems like there's more room for customization with HTC phones...
Anyway, I found that TWRP won't flash cm11, but Philz_touch will. If you're rooted, grab rashr off the play store and you can flash both of these recoveries right from your phone. I'd go with TWRP 2.6.3.0, though, since the latest didn't like my backups.
Then once those are installed, you boot into bootloader and volume down to Recovery and it'll pop up in a few seconds where you can take backups (<--DO THIS!) and flash new roms and kernels and such.

Have you tried Sunshine S-OFF, it will cost $25 but it is worth it. Once you get S-OFF you can change your CID & MID then flash the GPe RUU or ROM.
Thanks a lot for your replies!
I have actively tried figuring this out alongside reading for my exam today, and recently found and interesting option to work around S-on. My total goal is getting GPE Lollipop on my HTC, and I just now found a thread discussing using a backup from OPs phone. According to many users in the thread, they have been able to recover this backup and successfully run Lollipop with S-on. I did consider buying Sunshine, but due to finding the backup-option, I wanna try the free alternatives first. My goal is like I said running GPE, and I will most likely not install other roms on my phone.
My phone has an unlocked bootloader, custom recovery CWM v6.0.4.8, and my phone is rooted with SuperSU v2.37 at the moment. This might change some since I'm trying to recover a specific backup as my current tactic.
Your replies have definitely added to my understanding of the workarounds, and are much appreciated. If the backup-method don't work, I will try your methods!
PS: I posted in the backup-thread asking some questions. I'm posting my link here to string them both together in case someone else looks for an solution to the same problem I had.

Want to go back from 100% stock Lollipop to 100% stock KitKat

My M7 isn't rooted, nor does it have any mods. It is and has always been 100% stock. Last week I received the OTA update to Lollipop and since then I'm experiencing a lot of problems (like so many others). But even without the problems, I just don't like Lollipop. I don't like the new notifications, I don't like the new toggles, etc. So I would like to go back to KitKat. I have found a few tutorials but all assume your M7 isn't stock. And like I said, mine is.
A few questions:
Does the fact that my M7 is still 100% stock make reverting to KitKat easier?
It's been many years since I last flashed my phone (it was a HD2) so I really don't remember what's involved. I do remember however I need the proper RUU. How do I find out which RUU I need (I'm in the Netherlands)?
Are there any tutorials that explain how to go from stock Lollipop to stock KitKat?
If these questions have been answered a thousand times before, I apologize. I just couldn't find those answers then.

should really post this in the help and support section.
but if you are 100% pure stock then the only way you can back flash is to get s-off first, and that will cost you $25 using sunshine s-off tool, there is no other way to backflash.
also if you do decide to get s-off and go back to kitkat, your phone will constantly nagg you and give you notifications about the Lollipop update.

well post your fastboot getvar all without imei and serial number so we can locate the correct stock files and then get s-off using this: http://theroot.ninja/
Re $25, I did not pay for getting S-Off, I do remember the procedure was pretty much automatic and simple.
If you need to go s-off, but don't know how, pls let me know - I will look into my old files.
PS. I like the new Lollipop UI. But, power management is something that makes me think of rolling back to KitKat, too. I'm rooted and s-off, though.

Sunshine as far as I know is the only way to s-off HBOOT 1.61, 1.60, and 1.57, unless you have used it before, then its free to s-off the same device again, you only ever pay once.
and @Zippy1970 will be on 1.61 HBOOT as he has the official 100% stock update.

[Q] Basic steps from unlocked to Sprint updates

I'm overwhelmed by all the shop speak regarding the android OS. Everything's an acronym, and everything sounds vaguely similar to everything else. Stock recovery, stock rom, stock firmware, factory reset, I'm a computer literate person, and I don't know what the difference is between any of these things, I only know that they're serious.
So here's my situation:
I have a Sprint HTC One M8, unlocked with s-off.
I have adb installed on my PC, TWRP and Super SU installed on my phone,
I need to install system updates, first to install KitKat 4.4.4, then immediately after, Lollipop.
When I go to install
my phone boots into TWRP mode
I go to update
select the update zip
swipe to flash
and get "updating partition details... failed"​
I gather that I'm supposed to first restore to a stock recovery, and I think I found the correct one here, but the instructions I'm finding are very convoluted. I need to either unlock or lock my bootloader using adb. I need to flash one of the downloads on that page, but I'm not certain which one, how to flash it.
I understand that this isn't a forum for newbies, but that's just the thing, I'm not usually lost when it comes to this stuff, which makes me think many others are probablylost as well.
Can anyone clearly explain the steps I need to take, with a minimum of acronyms, to do whatever you do with a stock recovery to then be able to install Sprint updates?
I posted this question in a different way back in November and had one member keep posting unhelpful answers until the whole thread got hijacked by piggyback questions. I've also found step by step guides that each conflict with one another. One may have 5 steps and the other may have 12, and in one way or another they've always gone off the rails until they no longer seemed to apply to my use case.
If you can help, thank you.

First things first, this is a forum for all kinds but there is a Q&A section.
On to the update.
The first thing you need to do is boot to fastboot and type "fastboot oem lock" without quotes and press enter.
The device should be locked and from there you should be able to run the RUU (ROM update utility) that comes directly from htc, no need to do the incremental updates from KK (kitkat) to LP (Lollipop) unless you are looking to do something specific on a certain radio or firmware.
No need to flash stock recovery if you run the RUU, only lock the bootloader.
The RUU files are found on the HTC website or in this thread: http://forum.xda-developers.com/showthread.php?t=2729173 and you should find the directions there, just follow the S-on procedure if you are S-ON, you would know because at this point the only way to obtain S_OFF is to pay 25$ to use the Sunshine app.
This might be able to be moved to the Q&A by a mod and there are plenty of users and devs around here willing to help, just ask questions and try to follow the directions first.

Thank you very much, I'll run through these steps.
Question, I installed a couple firmware patches after I got s-off. when this is finished, will those be overwritten? Will my phone still be s-off, or would I have to pay to have that done again?

So you are S-OFF, OK.
No, the S_OFF is tracked by the device I believe, and would still be able to be used without having to pay again. I have read that many places.
I would not do the full RUU if you are s-off, but the thread I linked has zips to flash firmwares and roms and keep S_OFF. I am still on so I have no experience with S-OFF but I would not lock the bootloader until another s-off user confirms.

I got a little wreckless and just went ahead and tried it. Everything worked. I'm running Lollipop, I still have S-off, and I just re-rooted through the HTC dev program. The firmware patches I installed were overwritten, but, you can't have everything.
Thank you very much, I'd been dealing with system update messages for months.

What do you mean by patches? Just specific bits of firmware? I don't really know of any benefits to having specific bootloader or hboot or radio over another. It used to matter back in the day but I think it is best to have the most updated if you are going to run a newer ROM anyway.
Also, if you are S-OFF you can always downgrade any of them at any time. So if any of the patches you had before gave you any benefits you can always run them again.
Glad you got it taken care of. On any note, if you muck something up you can always run the RUU to get back to stock. HTC did us a huge favor with those.

It's a patch that adds Harmon Kardon sound. Then I incorrectly remembered an app that enables Snapdragon audio (which is far superior to HK sound) but that's not firmware, you just need a rooted phone to be able to drop it into the system folder.

Finally Rooted My HTC One M7, Now What....

Well I've finally rooted my HTC One M7 after months of saying I'll do it soon, I've also flashed the latest CWM recovery on there but now my question is what do I do now? I've downloaded some apps that need root permissions but nothing great. What I want is an OS that uses minimal RAM and battery. I've seen LiquidOS but that runs Android KitKat, are there any that run on Android Lollipop?
Thanks

Normally you only root a phone if you need to use something that requires root privileges. Its like saying: I finally managed to open that locked door to access this room where there is nothing inside that I really need... now what?

If you want to flash a custom rom, you don't need to root, only need to unlock the bootlaoder and flash a custom recovery (like you already did in the process of rooting). Most custom roms are pre-rooted anyway. There a lot of lollipop roms out there, check in the development section of this forum (Sense 6/7 + Lollipop or GPE lollipop). What will be the best rom for you? Its hard to tell, test a few one yourself, its the best way to find out. If you want something stripped down then probably a GPE rom will fit your needs otherwise if you prefer to have a more "complete" experience I would say go with Sense (6 or 7) rom.

yep,
Do a Nandroid backup of your current setup before flashing anything so if something goes wrong, you can simply restore that backup and use your phone. Better to save the backup your computer so if its wiped from the phone accidentally, you still have a copy.
read the OP of the ROM you want to flash twice before proceeding
Newer Sense roms (lollipop) requires a recent firmware on your phone to work properly (a 7.xx.xxx.x version). Confirm that before flashing the rom using "fastboot getvar all". The version-main number is your firmware version.
Ask questions if you are unsure about something, better than bricking your phone
You might also want to check if there is a RUU to return your phone back to stock in case you need to in the future. (your version-main will tell you the RUU version you'll need)

Do I need to do anything with the bootloader, its currently unlocked but I've read on other forums some of them require the bootloader to be locked but S-Off or something? There's nothing about this in the Viper install instructions I'm just wondering if it's relevant?
Also an RUU, is that basically a recovery file with an OS? If so would I still need to look into this if I've already done a Nandroid backup?
Thank you for all your help.

You don't need S-OFF to flash a custom rom, only an unlocked bootloader with a custom recovery.
A RUU is a factory image. It can reflash the software and firmware back to stock if needed. Its useful to know if there is one for your phone just in case you can't restore your phone using your backup for whatever reason. Tell me what your version-main is and I'll tell you if there is a RUU somewhere.

Apologies this is a really noob question but how do I find that out because I've been looking at it says about using fastboot in a command window but all I get is "Waiting for device"
edit: apologies I just realised I had to actually be in fastboot mode *duhh* my version main is - version-main: 7.19.401.30
Thank you

There is no RUU for 7.19.401.30 but there is one for 7.19.401.22 which can be used on your phone if needed in the future. :good:
