[Q] Back to full stock with s-on

Hi guys,
need your help.
I have Europe M9, with S-ON.
Rooted it, and installed TWRP, installed custom rom.
How to revert it to full stock? I have sold the phone, and now buyer wants it back to way it were.
Thanks.

Thankfully it's pretty easy; just download your carrier specific RUU to restore to full stock. It's a Windows executable that completely wipes & return your phone to factory state.

I have bought it in Telenor Serbia it was on 1.32.401.15. Should I use any Europe RUU, or do I need to find one exact to match my carrier, and-or my firmware version?
sorry if being noob, but cannot understand this HTC's nonsense (s-on/s-off, cid, hboot...) thats the exact reason why I have sold it. to complicated for me...
I just want it up and running, and trust me, I will never EVER buy another HTC again.

Since there are two different versions of your firmware and I don't know which one is the correct one for you I would suggest you to use this firmware and downgrade to 1.32.401.8. This works because the aboot has not been updated until now. The process itself is very easy:
Download the RUU
Rename it to 0PJAIMG.zip (that's a zero at the beginning not an O)
Copy the file on an external SD card that is formatted to fat32 and not bigger than 32 gb
Boot into download mode
Follow the instructions that are shown on your M9's screen
Congratulation you are now back on stock rom and firmware
You have to use either this way or the fastboot flashing method since there are no RUU executables for the european version.
Btw: No one here forced you to buy the M9. Since it's simply a matter of taste it's up to you which device you choose. I personally prefer HTC's user friendliness in regard to bootloader unlock and rooting (compare it for example with Samsung's Knox system). But this is not the right place for that debate.
Edit: Since my phone is S-OFF I'm not completely sure but you might have to relock your bootloader or step 5 might no work properly.

I have the same problem, i wanna know how to restore it to full stock, i need it just in case something happens to phone and i need to use my waranty. I'm also on telenor serbia. Any detailed instructions would be much appreciated. And one more thing, will i be able to recevie OTA updates even though its rooted ?

Root by itself doesn't prevent OTAs, but changes to the recovery do. As far as I know, acquiring root (for this device) always involves flashing a custom recovery. So OTA aren't possible until the stock recovery is restored.

Do I need to have sd card, or can I flash it from pc using adb?
I have already tried this method, and fastboot gave me an error 22? Maybe I got wrong firmware. Will try again, thanks.

As far as I know, there is only one. Search in forums.

This is what I get when try to flash from adb.
used the file from post on first page,

try this RUU: http://androidruu.com/getdownload.p...6.02.50306G_2_F_release_429340_signed_2_4.exe

I'm also interested if it's possible to go back to stock from a S-ON with RUU_HIMA_UHL_L50_SENSE70_HTC_Europe_1.32.401.17_Radio_01.01_U11440261_56.02.50306G_2_F_release_429340_signed_2_4.exe

If you are S-ON you can only flash a RUU for your carrier and device. If that's the correct RUU for your phone, it will do it.

The question is where can you find correct RUU from specific carrier

So if you're an European open you can't really flash without s off?

There is a RUU list in the General forum. Not all configurations have RUUs, unfortunately, as it has always been with HTC.
http://forum.xda-developers.com/one-m9/general/htc-one-m9-dump-t3060545

By far the easiest way for the inexperienced is to use the windows exe version linked to a few posts ago .
If you're on 1.32.401.15 then simply flash 1.32.401.17 using the exe version. Simply run windows program and follow on screen prompts .
Main limitation if you're S on is it will only allow upgrade that is to go to higher number as described .
I think there is also a 1.32.401.8 exe but that's an earlier version so if you tried to use that and you were on higher version such as 1.32.401.15 then it wouldn't allow unless you had obtained S off.

One more thing, i received lates OTA update, but it wont instal because recovery isnt stock. I found stock signed, when i flash it will the phone factory reset or not ?

Flashing a firmware

Hello
My htc one m8 is the Asian version (HTC__044) , upon using getvar all, I noticed that my version-main was missing along with the os in hboot. If I were to flash a firmware, would I need to relock the bootloader? Would I lose my data on locking the bootloader? Also, im on base .401 , would I directly be able to flash a .707?
Thanks in advance.

If s-on, yes. Otherwise if s-off, no.
Also, be aware that with s-on you can only flash a firmware that is HTC signed/encrypted. Some are not, and require s-off.

How are you determining 401? From what I'm seeing, the stock software/firmware for your CID should be 707.
You should be able to flash 707 firmware (assume you want to update to Lollipop) on your version, provided the previously mentioned requirements are met.

Thanks for replying. I believe it may have been the rom ive installed that changed my firmware, along with the fact it writes .401 on my software information page. Yes the default firmware should be .707 which I believe is also the main cause of my inability to connect to 4g in my area.
So assuming I find a signed firmware for .707 I would simply be able to flash it on the .401? Or would I have to still relock my bootloader.
Also, would the empty os/ version-main be a problem and if so how do I fix it.
Thanks for replying as you've also helped me a great deal the previous time.

Flashing a ROM will not change your firmware. It does change software number, so if that is where you are getting 401 from, that is normal. Software number is just the base of your current ROM, not your firmware number.
Your firmware number is indicated on your bootloader screen under "OS" and also as "main version" when doing getvar all.

Are you s-on or s-off?
If still s-on, there is no way you could have ever flashed a 401 firmware on your phone. I still think you are confused between software and firmware numbers, and I don't guess that you ever flashed a 401 firmware.
If you are s-on, I still think you are on 707 firmware, and there is some other factor causing your 4G problem.
Yes, you need to relock your bootloader to flash 707 firmware while s-on. If you are s-off, you don't need to relock the bootloader.

It shouldn't be a problem. It will be fixed if you flash a firmware.
This bug was caused by older versions of TWRP. If you flash a current version of TWRP after flashing firmware, the problem should not re-occur.

We always like repeat customers, and satisfied ones.

So is it possible that I am actually on 707 but my rom is making it show 401? Im terribly sorry for my lack of understanding of this whole situation.
Would using the twrp app on the play store update twrp? It should fix the empty main-version ?

I know in the past, folks have often used the word "firmware" to mean the same as the ROM. But you should probably erase that notion from your mind. On this device, the word "firmware" is used specifically to partitions that are not flashed when you flash a ROM, and include hboot, radio, WiFi, Bluetooth, and others.
Yes, your firmware may still be 707 (which can normally be found as OS number on hboot screen, or main version when doing getvar all); while your software (ROM) which is shown in Settings>About>Software information can be 401. Firmware and ROM are 2 completely different things.
I've asked twice now, are you s-on or s-off?
wasdapple said:

TWRP Manager app will update TWRP, yes.
You can also just download the latest version and flash with fastboot, which is my preferred method: https://twrp.me/devices/htconem8gsm.html
However, this alone won't fix the issue of main version missing, I don't believe. It will only stop if from re-occurring. But the only way to get the main version back is to flash a firmware. After that, having an updated TWRP will stop if from main version displaying "blank" again. If you use an old TWRP, it will blank out the main version again.
Get it?

I'm sorry I kept forgetting to reply to that, I am actually s-on.
So for instance I want to be back on 707 I should just revert to rooted stock?

Than its simply impossible for you to ever have flashed a 401 firmware. Some of the firmware partitions (hboot, radio) are write protected with s-on, and can only be flashed with your CID version firmware (707).

Yes, rooted or unrooted should be fine.
But you will want to make sure your firmware and software versions match up. What are your hboot and radio numbers? Do you remember if you were on Lollipop before unlocking the bootloader?

My hboot would be 3.19.0.0000 and my radio is 1.25.21331147A1.06G
Yep I was on lollipop before unlocking my bootloader.

You can get the stock 4.19.707.2 nandrioid here (Post #2): http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
Keep in mind, this is a TWRP "nandroid" backup, not a flashable ROM zip. So follow the directions carefully to restore this stock nandroid.
Also note that this is the stock ROM, not the firmware.

Would I get back my 707 if I flashed this instead http://forum.xda-developers.com/htc...-sd-14-19-707-21st-android-5-0-sense-t3010391 ?
im seeing an Asian wwe base and it is 707.
Also I wouldn't be able to dirty flash a completely different rom right?

Not sure what you mean by "get back my 707", and you need to explain more clearly.
If the intent is to return to 707 firmware, its not needed, I'm confidant you already are on current 707 firmware. And flashing a ROM does not change your firmware (as I've already explained multiple times).
If the intent is to make the main version appear again, flashing a ROM won't do that either. As mentioned, you can only make that reappear by flashing a firmware.zip (not a ROM.zip).
If the intent is to just return to a 707 ROM base, then yes the ROM you linked will do that. But the only reason I see for you to do so, is to see if it helps your network issue. Using ROMs of other bases will not normally affect network service (as long as your carrier's APN is correct). And I've already linked you to stock 707 nandroid, which is probably the best baseline to troubleshoot from. Or are you not comfortable with the nandroid restore process?
Again, you haven't really explained what you are trying to accompish; so its hard to answer the question.

If the ROM is a similar enough base, it might be possible to dirty flash. But its not recommended, and still possible to have various severe bugs, or not even boot. Therefore, full wipe is normally recommended when moving between different ROMs (and often even major updates of the "same" ROM).
Any person flashing ROMs should know how to backup and restore their personal data (using Titanium Backup and/or other means) when moving between ROMs.

Sorry for my vagueness in my previous post. Currently in my phone settings, the build number is 4.26.401. , which is the base of my current rom? So supposedly if I flash an Asian wwe would I get my software base back to a 707 as in the link.
Also, you mentioned for me to flash my firmware as per my cid, which could be found in most firmware dumps? Would be it be possible to link one to me? And if I am in fact on a 707, do I still flash 707 firmware?
The reason why I an unwilling to go through with nandroid is that I am not exactly looking to restore to stock, I like to have customs roms and the root capabilities. My ultimate objective is to get back to 707, or at least get it to appear on my software information screen. To my knowledge, 401 is for the European countries and the basebands for 4g LTE is different, thus I am unable to find out why if I am s-on with my firmware and radio intact I could not connect to my local 4g LTE, and to my point of view, only through flashing a firmware affect everything.
Im sorry for this large amount questions and extremely grateful you have taken the time to tend to it. I sincerely apologise if I seem to keep insisting that my firmware has changed despite your reminders.

I've actually been trying to update the firmware on my M8 today as well, but when I go to "flashboot flash zip firmware.zip" I am returned the message "not enough space."
I've cleared the cache successfully, and that didn't open up enough space. I tried to delete userdata, but it wouldn't let me do it remotely.
So I'm a little confused as to my next move here...
and I've relocked my phone and s-on.

Yes. You will get your software number back if you flash a 707 based ROM, such as stock.
So, here we go.
Download this 4.19.707.2 RUU onto your PC
When the download is finished, plug your phone into your PC, double click on the downloaded file, and follow the prompts. This will update you to Lollipop and you will be on the stock ROM again.
Since you are S-On, you will first need to relock the bootloader.
In fastboot (obviously) fastboot oem lock before you proceed with this.
Also, THIS WILL WIPE YOUR PHONE, so be sure to backup anything that is important to you.

Is the ruu rooted, or purely stock pre-root?

If the intent it to return to 707 based ROM to see if that helps your 4G issue, then yes the custom ROM you previously posted will do that. It will also make 707 appear for software number in the phone Settings.

I was more talking "if" you can find the 4.16.707 firmware. The main firmware collection I refer to doesn't have 4.16.707, just old 707 firmwares (which you don't want)]: http://forum.xda-developers.com/showthread.php?t=2696282
If the firmware can't be found, the RUU listed by xunxholyx is your best bet if you really want to flash the 707 firmware. But I really don't think this is needed. As I'm nearly 100% sure you are already on the current 707 firmware, and the only benefit of flashing the 707 firmware (by RUU) is to get the OS number to appear again on the bootloader screen and on getvar all (which is really not that important).
On the other hand, RUU to full stock may be a good way to troubleshoot your 4G issue, especially if flashing the 707 based custom ROM still doesn't fix the issue. RUU is not just a stock ROM, but a complete factory image, complete with bootloader, radio, etc.

Yeah, they are hard to come by. I was helping a user here six to eight weeks ago, and told him I didn't know of any Asia RUUs. He came back the next day replying that he found one, so I asked for the link and gave it to Sneakyghost and Alex (from AFH) to upload to androidruu.com
They have a few that aren't common there, and are always looking for more hard to find ones. If you come across one, you could PM me or Sneakyghost to have it added. Always nice to have a good RUU repository to go to.

Hey everyone. I'm having a similar issue, and I don't want to start a new thread, so I'm going to add on to this one.
I've been on AOKP since it was released for this phone, so I've missed out on some OTA updates. Every time I try to flash a Lollipop ROM I get all these weird issues (WiFi not working, systemUI crashes, etc.), and after reading a few threads, I believe its an issue with the firmware.
I tried going back to stock, but the only Nandroid backup I could find for my phone isn't compatible with my firmware (WiFi refuses to work, only data). So I was wondering what else I could do to update the firmware. Reading this thread, it looks like the RUU is another method, but I'm not too sure how to get started with that, or which one to use, as my OS in the Bootloader and my version-main is blank.
Any advice is appreciated, please let me know if you need more info.

Lots of trouble unrooting M8...

I've been having a hell of a time trying to unroot my HTC One M8... It was an AT&T one I converted to Skydragon GPE, S-off. All the resources I try to use keep on failing somehow—anyone have suggestions? There's a million different tutorials on how to do it and none of them seem to work for me, getting really frustrated...
(I would link the below guides I've been trying to follow but I'm too new a user so it won't let me):
- The Unlockr guide: The Hassoon toolkit no longer exists.
- DroidViews guide: Everything's good until I try to restore the RUU image, then the executable fails with no explanation. Same when flashing the RUU from HTC's website.
- Restoring from a Nandroid backup in TWRP: Also never makes it through the entire process, I'd have to rerun it to see what the particular error was.
Ughhh is there any definitive set of steps I can take to actually restore to default settings? Preferably with the tampered flags not tripped, but honestly I don't even care at this point... Do I need to flash some stock AT&T HTC One M8 firmware or something before doing this all? Where might I be going wrong? I know it's vague but I'd love a solid walkthrough.
Thanks everyone

The simplest way would be to get an RUU from htc.com for AT&T, putting your phone in fastboot mode (power off, then pressing power+volume down, and selecting "fastboot"), and then simply launching the ruu. It should restore your phone to nearly being stock, except for your CID number and s-off. There are tutorials on how to change your cidnumber, however i am not sure how to turn s-off back to s-on.
http://www.htc.com/us/support/rom-downloads.html here you can find appropriate downloads

Ok, firstly, you might check out this thread: http://forum.xda-developers.com/showthread.php?t=2733523
None of the instructions require the use of anything beyond fastboot/adb. Also, make sure you put your CID/MID back if you changed them to run GPE. That isn't required to run Skydragon, but if you have altered them, put them back. Then rerun the RUU. Finally, since you are S-off, you can trivially fix any flags, so don't worry about that. (Running the RUU successfully will clear the modified flag anyway)

So I did this, starting from the Skydragon Sense 7 ROM:
made nandroid backup
flash 1.54.401.5 firmware
set cid to CWS__001
run RUU for the latest AT&T one. It says it will update from 1.54.401.5 to 2.6.502.16.
Result? Error 155 "Unknown Error", no other information.
Any ideas?

Don't know what guide that is, or what RUU it tells you to use; but be aware that there are many RUU versions for the M8, and the RUU needs to be the proper one for your CID and MID. Also, Win7 or 8.1 is recommended (Win8 and especially Win10 will cause the RUU to fail).

Did you actually "fully convert" to GPE, or just flash Skydragon GPE?
What color is your hboot screen?
What hboot number, radio number?
The toolkit still exists. But it hasn't been updated in a very long time, and will therefore cause many many issues. So don't use the toolkit!

hboot screen is white. hboot number is 3.19.0.0000. radio number is [email protected] I was using windows 8.1, though the computer I was using only has USB 3.0 ports (Apparently people say 2.0 is better?)
This is on the firmware that I was using for Skydragon, I can reflash the other firmware I had used for the failed RUU upgrade if that would be useful.

I'd leave it alone, and just try running the RUU.

Yes, folks have reported issues with RUU and USB 3.0. You can always try, the worst that will happen is the PC won't be able to talk to the phone.
Another user mentioned you can "disable" USB 3.0 in settings, but I'm not familiar with that.

OK, I've tried doing it on a computer that has USB 2.0 ports and once again, no go.
Trying to run the Developer/Unlocked RUU on HTC's website, it's stuck forever at 0/7 sending.
Trying to run the AT&T one, it errors out with a 155: Unknown Error message as soon as it boots to RUU mode.
Any other thoughts?

I think this means you need to relock your bootloader (required to RUU with s-on).

Full stock Dev Ed M8 won't take OTA or RUU for MM

I have a Dev edition M8 that i zip RUU'ed back to lollipop. i took a security update successfully, then the 3 preinstall updates in prep for marshmallow. however, I now get an error when taking the actual OTA for marshmallow. I am s-off and bootloader unlocked. I then downloaded the RUU from HTC to run the exe, but i always get error 155. I read @Sneakyghost post about firmware and it said it was either region ID's not matching, or the bootloader being unlocked. I don't see why the unlocked bootloader would be a problem when im s-off and its a dev edition, which is bootloader unlocked out of the box. Anyone know what is causing this?

heres my recovery message, just to maybe help troubleshoot it. it mentions userdata being busy (i got an error in the zip ruu flash for userdata, had to flash the ruu zip twice to get an okay), then kidmode missing. not sure what to do besides flash the firmware from http://forum.xda-developers.com/htc-one-m8/development/rom-stock-unlocked-developer-sense-7-t3262894

Modified system apps, sir. That's what it is. Did you root your system?
Edit:
Maybe not. Maybe just can't find those apps cuz it can't mount data.
Something wrong there.
No idea.
I'll see where I end up.

i did a factory reset from stock recovery, and kid mode is present now, maybe im onto something...
Edit: not rooted directly from a factory ruu zip (well, hopefully the zip creator did a factory dump and was unmodified) but kid mode wasnt an option before the factory reset

ok so i got mine to work.. apparently the zip RUU isnt good. i ran the exe 4.16.1540.8 from here http://forum.xda-developers.com/showthread.php?t=2701376 and then updated ota from there without issue. so my guess is the RUU zip wasnt perfect system-wise,while the exe is straight from htc.

zip was from the same thread, i tried the exe instead because it was an HTC file instead of a contributor. now on MM sense. The 6.xx RUU refused to work no matter what i did, so i OTA'd to the latest version.

I seem to be having an entirely different problem. After swapping cables, phones and laptop ports as well as updating drivers, it appears that the usb port of my M8 is broken. I'll have to see at someone else's computer, maybe tomorrow. Pretty frustrating right now as I'm liking the M8 better than my M9 and M7.
[EDIT]
I could stabilize the connection enough to run another, international RUU. The RUU worked fine while the 6.12.1540.4 kept getting stuck at either "checking header" or "sending" - both times with a successfully established connection. I already tweeted HTC asking to have that RUU checked. I assume your findings were correctly indicating a bad RUU, since a.) It also didn't work here and b.) people from my team have confirmed seeing several fail scenarios with that RUU spread over XDA.
Guess that's that then. Thanks for raising the issue. I would have messed around with it much longer otherwise since the error messages are not clearly pointing towards a broken RUU.
[EDIT]
More updates: searching the M8 forum for 6.12.1540.4 turned up this: http://forum.xda-developers.com/showthread.php?p=64320571
That'd mean the RUU fails at the hboot pre-update reboot. All that's needed apparently is to flash only the hboot manually first, so it can proceed. Hence also error 155 which usually indicates issues with the system image. You experienced that most likely because the older hboot couldn't extract the system.img from the rom.zip.
Usually, the procedure is:
RUU updates hboot
RUU reboots to boatloader
RUU updates rest of firmware
RUU sends over the system image in parts
Hboot now decrypts and flashes the part.zips
It just looks like mandatory hboot-first-flash didn't happen right, either not rebooting after it or not flashing it at all.
However, this seems to be fixable by running the hboot/firmware package first and then the complete RUU.

I have a T-mobile HTC One M9. Can I update to nougat using the unlocked RUU?

Hi, I was wondering if it is possible for me to use the stock RUU to update to nougat on my htc one m9 rather than waiting for t-mobile to release a verified rom later in the year?

Yes u can. Just make sure that u are s-off and bootloader unlocked and then flash the dev edition ruu and u will get nougat.

Not quite. To flash the developer RUU on a T-Mobile branded M9, you'll need to change your MID & CID to match the SKU of the developer edition RUU. If you don't know about these acronyms, stop what you are doing and read up. The FAQ section of the M9 readme thread, question 9, walks you through converting GSM phones (like the T-Mobile version) to the developer edition.

Not until Sprint releases the Android Nougat update.
The only update the is currently available is for the developer edition of the M9, a GSM model. Sprint is a CDMA carrier and incompatible with GSM.

Thanks for clarifying.
And you cannot flash on sprint or cdma phones. The ruu is only for gsm phones.

RUUs have the firmware along with everything else. While I'm pretty sure there's a way to flash individual components (radio, firmware, et cetera), that is beyond me. I stick to using the RUUs, and recommend them heartily. The easiest method is the SD card method - outlined in that same post. You'll end up wiping your internal phone storage (so back up what you care about), but it'll get you to the latest and greatest for the M9.

Really? I read that you couldn't use an RUU because verify key on firmware v1-3 is different from the one on v4, so you need v4 firmware to use a v4 RUU, which requires using a method. So I converted to dev/ATT/unlocked, flashed a v3 RUU I found online, and now I'm going to try to update to v4 which is apparently safer. If this fails, I'll try the RUU. After all, this is all vanilla to HTC so it should tell me if it won't work.

Tried to use an RUU. Got a signature error of some sort. Can't remember the number. RN it is taking OTA updates smoothly. Now, it will either get to v4 eventually through the OTA updates, or it will cut off at the top of v3 (in which case I have done something horribly wrong). I will try to flash RUU after I get v4 through OTA, just for fun and for the sake of the community
Edit 1: v4 finally showed up through OTA. 2GB Downloading currently. Will still RUU to double check compatibility. Will post back with success or not.
Edit 2: v4 was successful, device convered to HIMAULATT. Now flashing the Dev RUU, which works. It didn't work on v3. Therefor I was correct, and RUU v3 -> v4 isn't compatible.
