[tutorial] How to upgrade One V with an OTA update / RUU to revert to stock

As there are many questions on how to do OTA update & to revert to stock after a device is rooted and bootloader unlocked; I made this simple guide which I hope will help the newbies especially.
NOTE : always do a backup and a nandroid backup before trying any of these.
OTA update:
A) ROM is stock, bootloader unlocked, stock recovery and not rooted.
- just run the OTA update, there is no need to relock the bootloader
B) ROM is stock, bootloader unlocked, CWM recovery and not rooted.
- flash the stock recovery that comes with your RUU, extract the RUU for the stock recovery.
* boot to bootloader
* fastboot flash recovery recovery_signed.img
* fastboot reboot-bootloader
* fastboot erase cache
* fastboot reboot
- run the OTA update
C) ROM is stock, bootloader unlocked, stock recovery and rooted
- download OTA Rootkeeper from Play Store
- run the OTA Rootkeeper and click protect root
- run the OTA update, there is no need to relock bootloader
- Once done, run OTA Rootkeeper and click restore root
D) ROM is stock, bootloader unlocked, CWM recovery and rooted
- download OTA Rootkeeper from Play Store
- run the OTA Rootkeeper and click protect root
- no need to relock bootloader
- boot to bootloader and fastboot flash the stock recovery
- run the OTA update
- Once done, run OTA Rootkeeper and click restore root
E) ROM is custom, bootloader unlocked, CWM recovery and rooted and you have a stock nandroid backup
- flash the stock boot.img if after nandroid restore, you have a bootloop
- flash the stock recovery.img
- relock the bootloader - fastboot oem lock
- boot your device and run the OTA update
F) ROM is custom, bootloader unlocked, CWM recovery and rooted and you don't have a stock nandroid backup
- if you dont have the stock nandroid backup, you need to run RUU
- before you can run the RUU you need to:
* flash the stock recovery.img
* flash the stock boot.img (maybe no need)
* relock the bootloader - fastboot oem lock
* run RUU
- run device setup
- run the OTA update
Flashing RUU to revert to stock or to update your One V after you have a custom ROM installed.
- you must have the correct RUU for your device.
- if you are not sure, download CID Getter from Play Store and run it, it will show your CID.
- with your CID, you may be able to find a correct RUU for your device
then
1- in fastboot mode - relock the bootloader : run command fastboot oem lock
2- in fastboot mode - flash/run/double click the RUU; follow the updater instruction - next,update,bla,bla,bla until it finish
Note :
Error 155 - usually wrong recovery.img /wrong boot.img or bootloader not relocked
Error 140 - wrong bootloader / bootloader unlocked
Error 131 - wrong RUU for your device

If I have a nandroid backup from my stock (nandroid after it was rooted), how can I get rid of root? I need to lock bootloader also because I need to return my product. Also, I have the kernel img and recovery img (need to flash those also because I have flashed custom kernel and cwm).
So my guess is that:
nandroid restore
go to fastboot and flash boot.img
go to fastboot and flash recovery img
go to fastboot and relock bootloader.
but how do you get rid of root?

Reflash system.img is the no-fail way.

System.img is the rom itself right? If yes, by reflashing it, the root will still be there because the nandroid was AFTER it was rooted. And I didn't found my RUU. I have found one which is the same as mine but the last number .x differs from mine (I have .4 and the RUU has .3)...

your going to need the ruu buddy, i have to do the same, the kernel shows up as root blah blah blah. kernel recovery and rom itself need flashing.....

Would you be okay with just removing the superuser.apk or did you also want the binary gone?
One of the possible options is to modify your nandroid backup so that both files are deleted (and not restored), but I'm not sure if CWM complains if the backup has been modified.

Restore your nandroid backup
Reboot your device.
Open the SuperSU, and click Full unroot (it will remove the app, apk & su library)
Reboot to recovery
Make a new nandroid backup (this time there is no root for safekeeping)
Reboot to bootloader
fastboot flash boot stockboot.img
fastboot erase cache
fastboot flash recovery stockrecovery.img
fastboot erase cache
fastboot oem lock
now you are back to stock rom without root and relocked

Thank you so much, will try it tonight because tomorrow I need to get my unit to replacement. I didn't knew how the process worked since I never did it (I work with android for 3 years now).
But I have a question. If you open su and you click full unroot, why do you need to make a new nandroid and flash that?

Because your old nandroid has SuperSU.apk and SU library in it.
New backup will not have those because you already remove them before new nandroid is made.
So you'll have a new stock nandroid without root.

Well, the point is that I will replace this unit with another one since this one is not working with Orange carriers. My shop was in talks with HTC service to get an unlock code but they failed to do so, so they said it is ok to change the unit. No need to keep a nandroid backup since I don't know what software version I will have on the new phone. Thank you for your help!

No, not boot into CWM.
Remember how you go to bootloader when you first want to unlock your bootloader ? You press power + volume down, that is boot to bootloader.

Please make sure you're flashing to recovery, not boot.
Connect your phone to your computer via USB. I'll assume you have the necessary bootloader/adb drivers installed.
Open up a command prompt to wherever your recovery.img is and type (this assumes you can easily access adb/fastboot from anywhere):
adb reboot bootloader
Phone should reboot into fastboot. From there type:
fastboot flash recovery recovery.img
It should then flash the stock recovery.
I would recommend taking a look at the HTC All-in-One ToolKit in the Development forums. It might simplify it for you.

To get back to you guys, I have followed these instructions and I am back to stock. The only thing that should worry me now is that the bootloader says "RELOCKED" instead of "LOCKED" but I don't think this is a reason why I should loose my warranty since we've done it using HTCDEV method.
It was easy enough because I had my nandroid backup. Such a joy to have one of these at hand!
Thank you all for the infos. Tomorrow I'll get my replacement :yuhuu:

[Q] After installing RUU I still got ROOT

Hello,
So I had stock rom with XM-Kernel and I wanted to go back to full stock.
So I did "fastboot oem lock" and then installed the RUU, but when I go to software settings the Kernel version is "[email protected] #1" and I still got SuperSU.
When I go to recovery I get a red triangle and a phone under it so I think it means it's the stock recovery (as it should be).
What should I do? I want to update my device with a original update, and I don't think I can do it with the root.
Thanks.

I think its suppose to say that. Try and install an app like greenify to see if you have root acces. If you do not have root acces it's unrooted.

Lol yeah that is the stock kernel
No worries after a ruu you just can't have root access ! And If you really have it you can unlock it, flash a custom recovery and wipe the crap out of the phone
Then relock and run the ruu again.

Thank all.

[Solved] Installing OTA with S-Off and Root

Update: Well, I took the plunge on my own, and everything worked fine. Flashed firmware.zip, went to stock recovery and flashed OTA, and voila, all good.
So I've bought an HTC device for the first time. I did S-Off and unlocked bootloader and rooted as well. Now, there's an OTA available (I have the Asia_India variant), and I wanted to ask just how would I go about updating.
Here's what I've surmised till now:
1. Revert changes to system partition or it will fail to update (I moved some system APKs, but I saved them for such a scenario.)
2. Flash Firmware.zip to get stock recovery back.
3. Install OTA normally from the notification.
However, I'm still not sure what else I'd need to do (unroot, using the option in SuperSU?), so was wondering if someone could help me out. I've made backups in Philz and TWRP recovery both just to be sure.
P.S.: I extracted the firmware.zip file from the OTA, and tried to open it, but it doesn't open in apps like WinRAR. Is that normal, with the file only flashable via fastboot?

Personally, I'd say remove root just incase it stops the OTA but others will say it doesn't matter so long as the rest of the system is 100% stock as HTC intended it

For OTA updates after having a custom recovery, just flash your ROM stock recovery (search XDA all are available) then run OTA as you normally would and then flash your custom recovery again (if you like to get root again). However personally I would not do this with S-ON device, probably it's better if you're S-OFF while doing this to avoid any problem.

I am also interested in this. What would be the risk if I do this with S-ON? Assume I flash the wrong stock recovery or do some other mistake, won't I still be able to flash my custom recovery back from fastboot and get everything back up and running?
Thanks to whom will answer. :good:

So long as the phone still boots to fastboot, yes (although unlocking the boot loader will delete any backups so make sure you backup the backup to your PC before doing anything else!)

Thank you for your answer. As far as you know, being S-ON, is there really any kind of mistake one can do to brick the phone so that it doesn't even boot to fastboot?
Also, if my bootloader is already unlocked, no data wipe is going to happen again flashing a firmware/OTA in any predictable case, right?
Once again, thank you or anybody else who knows the answer.
By the way, are there any FAQs answering these questions? There are some FAQs here and there, but none seems to be very clear on these matters.

If you're S-ON there's not a lot you can do to brick the phone. You could wipe the ROM and have it not boot but you should always be able to get back to fastboot. This is where S-OFF is only handy to have if RUUs are about (it's the ONLY reason I am S-OFF, it's purely for a 'going back to stock' standpoint)
Yes, if the bootloader is already unlocked then you're good to go

[Q] Back To Stock

I have an AT&T M8 with 4.4.3
Its unlocked and rooted, firewater was unsuccessful with this error....****** device patched by HTC, you are out of luck *********.
Is there any way to return to stock without S-Off?? If so could someone please point me in the right direction?
I'm a newbie with htc and very aggravated with this phone.

Can you provide me with the link that says you need to be S-OFF to get your phone back to stock, where you clearly didn't have to be S-OFF in order to take it away from stock in the first place?
I'm asking this because you are one of many that I've seen recently that comes on here asking the same question, can I go back to stock while I'm still S-ON ? "Should I be S-OFF in order to restore a nandroid backup?" etc...I would really like to know where you guys get this information from?
The only thing that you'll need S-OFF for(when going back to stock) is to fix the tampered flag in the bootloader and to have it show "locked" instead of "relocked" when or if you locked the bootloader.
That being said, going back to stock from where? Did you flash custom ROMs? Or are you only rooted and unlocked?

My phone is stock, but unlocked with root, my main goal is to reload the original recovery, relock and unroot.
I was watching a video on how to use RUU and according to the instructions you had to be S-Off.

You need S-Off only when you want to remove TAMPERED and RELOCKED flags.
Other than that, you don't need S-OFF
You have AT&T device, AT&T forum is where you'll find more info.
Try this one : http://forum.xda-developers.com/att...-2-23-502-3-bootable-ruu-pc-required-t2860486
Important note :
S-On - you need to relock bootloader first before running it. So read and read the instructions
and there are many more guides on AT&T forum

You could use the AT&T RUU that is available on the AT&T forum.
At&t 2.23.502.3 - 4.4.3 Bootable RUU - No PC required - Mac friendly
Like the OP there said, if you are S-ON you should lock the bootloader first before using the RUU. I think that should take care of most of the other issues you have, like unrooting etc. Make a backup of any personal stuff you have on phone.
Or
Download unsupersu, flash it in custom recovery to unroot device. If you use SuperSU you can also go into settings for SuperSU and use Full Unroot. Reboot phone, can then uninstall SuperSU. Should be unrooted.
Flash back stock recovery for your device.
Relock bootloader - fastboot oem lock

Will this also restore the factory recovery instead of twrp that is on the phone now?

Post number 7
Post number 15
But I take it you didn't read at least the first 2 pages...
It'll take you back to stock completely, like the OP said in Post 15.
Just remember to relock your bootloader seeing as you're S-ON.

Thanks for your patience and help,
it worked flawlessly.

[Q] OTA Update Refuses to Install--Should be a simple fix

Alright. So I'm rooted with s-off. I had TWRP recovery. I flashed the stock recovery and got that going. Then I downloaded the OTA update and hit "Install Now". The phone instantly reboots, but goes into the stock recovery. I reboot the phone and I still have 4.4.2. What am I missing here?

This has been discussed many times,but is your boot loader unlocked? If so, your data/preload folder was wiped when the bl was unlocked and that is needed. Your system files must be 100% stock... Otherwise the update Will fail... You could always find the 4.4.3 ruu and flash in fastboot... That's what I did n worked flawlessly...

A few post debranding questions
Hi,
I've recently been exploring this forum and finally bit the bullet this evening and decided to try and de-brand my EE branded M8.
Steps I took were:
1) Used Sunshine to S-Off
2) Installed TWRP
3) Changed my SID from ORANG001 to HTC__001
3) Installed SuperUser
4) Downloaded the TWRP Nandroid for 1.54.401.5 - TWRP from http://forum.xda-developers.com/showthread.php?t=2701376
5) Used TWRP to restore the Nandroid and confirmed the software version was now 1.54.401.5
I have a few questions:
A) After the install the apps I had installed, my unlock pattern, contacts and wallpapers were all still visibile - is this normal? I had assumed the Nandroid backup would act like a factory reset
B) Is it safe to perform a factory reset, or do I need to somehow install a new image for it to restore from? I mean going through Settings -> Backup and Restore. Ideally having downgranded the software I'd like a "clean slate" - but I'm worried it will try and install a newer version and fail
C) Is it safe to perform an OTA update (this was one of my reasons for debranding)? Anything else I need to do?
D) Anything else I should be aware of? Any danger to leaving S-OFF and the bootloader unlocked? TWRP as the Recovery image?
Thanks

Thanks for the help. For the life of me, I couldn't find anything about having to have that bootloader locked. It's now locked (as confirmed by the "Locked" banner on the recovery screen), but the same thing is happening. Is there anything I can do short of flashing an RUU? Maybe there are some other major things that aren't stock?

You don't have to lock the bootloader again, whether you are S-ON or S-OFF doesn't matter.
When it boots to stock recovery, does it give a error message to you? If there was a problem during updating it'll show the problem to you.

Maybe the nandroid backup doesn't have data part, so restoring the backup alone will not erase your data because it doesn't get replaced. The best is make a factory reset in TWRP before you restore the backup

When you have TWRP installed, the best way to factory reset is Factory Reset in TWRP itself.

You won't be able to perform OTA as the system will say you have modified variant. What you need (a step that you're missing) is the proper firmware is flashed after your step 3. (also you may need a change of MID if the MID for ORANG001 is different from HTC__001; if they are same then skip this)

No danger, in fact you should leave it as it is, except when doing OTA you need stock recovery installed first (OTA won't work on TWRP)

Sorry I wish I woulda been more specific, there was really no point in relocking it... Once u unlock it the 1st time, the data/preload is wiped and relocking it doesn't bring it back..so u could've just left it
