need to get my one x+ back to stock, dont like custom rom. only problem is i have no back up as this is how i bought phone.
my cid is o2 001
have tried running o2 ruu 1.14.206.13.
please someone help???
Well, next time make sure you've backed up.
So there is a custom rom (yes its custom, but its stock with speed tweaks and such.) You should flash it. Do you know how to flash roms? Its here...

To revert back to stock you first have to lock the bootloader, which you can use the method I use by using an AIO noob proof toolkit that is in the android development section for this device. After you have locked the bootloader you can now run the ruu and the ruu will detect your phone and install everything back to factory. Now this will erase Everything on the phone including music pictures etc.
If you don't lock the bootloader the ruu will fail and not install. If you would like to install custom roms you will have to unlock the bootloader again.

Hey guys,
I seriously need some help, reverting my international HOX+ back to stock, as I am going to sell it.
My main problem is, that i have an o2 germany one, for that it seems to be impossible to get any suitable RUU
I am able to unlock / relock the bootloader, flash custom or stock recovery, flash any custom rom... not a problem.
But I'm stuck with the order of the steps! When I flash a stock rom (1.17.401.xx), my next step should be flashing stock recovery and then relock bootloader, right? I did so and got a security warning at bootloader and it seems, that there is no rom left on the phone.
How do I trick this, to relock, use stock rec. and stock rom?
Thanks for any help!!!
AW: Need help, going back to stock
you need the correct RUU for O2 brandings
yep. any news, where to get it?
thought, there might be a workaround...
I think there is no ruu atm.
I'll have a look for it.
AW: Need help, going back to stock
That would be very nice!

The only o2 ruu is this one:
http://www.androidfiles.org/ruu/sec...Radio_3.1204.167.31_release_289474_signed.exe
Based on your informations, you need a ruu for a german phone.
It doesn't matter that there is "UK" in the name.
The United Kingdoms are in europe, like germany.
Give it a try and tell me if it has worked or not.
If it doesn't work, open your Bootloader and flash an custom recovery/kernel/rom and wait until there's a dumped o2 ruu.

1.Go into the bootloader and make sure your phone is connected to your computer.
2.Relock your bootloader, using the cmd (Windows) or the terminal (Linux).
3.You make it with "fastboot oem lock".
4.Run the "ruu.exe" as administrator and let it work.
5.Drink a coffee and wait until it's done.
AW: Need help, going back to stock
Ok, many thanks for that!
I already tried that ruu, but maybe my fault was, I did not lock the bootloader, before.
Will try that, later this evening and give feedback

what about running ruu, extracting rom.zip and flashing this one? ruu could be 1.17.401 for example!?
will this work or result in a brick? is this method still possible on one x series? my evo 3d provided this while using a zip named to pc86img.zip (or very similar :cyclops
edit: if possible, will the phone check cid in the zip?
pretty much same here, except I am on O2 UK, and a higher version than the RUU available so it doesn't work, so frustrating, just want to go back to stock
alternate method would be: flashing a nandroid backup of a stock rom.
problem: don't own one
Is anybody out there, who can provide me a full backup of rom 1.17.207.xx with cid 02___102 o2 germany?
that would save my weekend, guys!
Hi.
I have the same problem but am on o2_UK i cant get back to stock.Doesn't mater whatever RUU i try is the same.
I have 1.17.401.1 cid02__001 and really badly need to go on stock ROM
Any help would be great.
Thanks a lot in advance.
Hello everyone
I hope someone can help me with this.
I have signal issues with my device, htc one x+, and thinking of sending it back as is still under warranty.
I have the revolution firmware on it and want to know how I can effectively set the original firmware on it so that I can then send it back.
Thank you

Depending on your devices bootloader (HBOOT) version and CID, you may be able to use an RUU to get back stock easily. If there's no matching RUU for your phone, you will have to search for stock backups and recovery matching your CID in order to apply stock HTC rom/firmware/recovery.
What is your bootloader version and CID?

reboot into bootloader (power off your phone and then press and hold power & volumedown button) there you can see your version number. If i remember right you need version 1.35 or lower to use a RUU, or your phone has to be S-OFF.

Thank you, what information you've used to decide what RUU to use?
is that because 1.17 is the latest version and because they bootloeader and cid I've given you tell you that my phone is european and factory unlocked?
In addition:
I'm aware of a few methods that can be used to backup: Titanium,through adb,clockworld twrp but none of these does a full complete backup.
What's the best way to back up all the date so that all my messages,contacts,apps settings and messages(viber,skype logs and chats) can be restored once I have installed the stock firmware.
Can you also point out a simple guide that shows me how to install the stock firmware?

HTC__001 is a so called WWE (world wide edition) cid and i mostly read about people in europe having this, don't know what country exactly. and RUU is bound to certain cid and we only have those few RUUs for this device, so if someone does not have a matching cid for those RUUs you aren't able to use them. Also (as you've seen) your phone's bootloader is S-ON (Security-ON) like most people here have it, which means we're not allowed to do everything with our phones, for example we can't flash boot.img in recovery and we can't downgrade our bootloader version. This is the reason why i needed to know your bootloader version because the latest RUU we have is this 1.17.401.1 which includes bootloader 1.35 if i remember right. So if you had version 1.40 you wouldn't be able to use it because you can't downgrade bootloader version.
As for backup: I use titanium backup for all my user apps and app data (settings, savegames, chats, ...) and SMS Backup & Restore for sms backup.
But you also will need root to restore those backups.
To use the RUU, simply connect your phone to your computer and execute it. It should guide you to the process.

Thank you for explaining.
So I understand that if there's no a compatible RUU, it will not be possible to downgrade to the stock firmware, does this mean that after using custom rom, if I endup with a higher bootloader, I can't get back to my stock firmware but only change from one custom to another custom rom?
Where do these RUU come from? aren't they supplied by HTC, I mean if someone has a device with stock firmware but want's to flash his/her phone again, how would they do it? (for example in iphones you can get stock firmware for every phone)
Is it there a way to create a RUU when I have a stock firmware so that in case I need to revert back I can use that?
I'm on version 4.1.1 i guess, which i think isn't the latest version, after going stock firmware, if I upgrade, will i get my bootloader upgraded too?
sorry for too many questions

Bootloader version is not rom version, custom roms won't update your bootloader. There's a difference between "firmware" and custom rom. you can update your phones firmware (bootloader etc.) with a cid matching "firmware.zip" from an OTA or RUU or on stock this is done automatically when applying OTA updates that include new versions of those. So if your bootloader version was too high, you can't use the RUU anymore and you have to get back to stock by using a stock TWRP/CWM backup and additionally flash stock recovery and boot.img and then relock your bootloader.
and yes RUUs are made by HTC, but there are no RUUs for latest software updates yet. either they don't exist or they're not leaked...
Your bootloader will probably be updatet to 1.35 if i remember right, but as long as the RUU includes the same version or a higher one, you're able to use it, so you can still use this RUU when used once.
just don't do OTA update to Sense 5/Android 4.2.2 or your bootloader will be upgraded to 1.72 and you won't be able to use any of those ruu again.
I just forgot one thing, I have linux at home, it's not possible to update through linux as it's an exe file.
is it there an alternative?

I'm sry, as far as i know there's no way for RUU on linux. But i think i remember seeing a guide (either here at some xda forum or somewhere else on the internet) with a description on how to extract the stock rom and firmware.zip (which includes stock boot.img and recovery) from a RUU. So you could flash stock rom, boot.img and recovery and then relock bootloader, which should have the same effect. But i think you will need windows here too...
After running the RUU, it asked me to update the image, however it fails and it stays on the HTC black screen.
I've searched around and the way to install the RUU is to run it until the wizard windows open, search the temp folder and and a file in it called rom.zip.
extract the recovery or recovery_signed file from it and use fastboot command on the phone.
However when I try to extract the recovery_signed file, winrar says it's corrupt
how can I solve this or is it there another way to install the stock firmware?
my bad I had to fastboot oem lock
back to stock ,thank you!
is it there anything else I need to do in order to make sure that my phone is in the warranty guideline( i mean softwarewise)
Now I have got the phone fixed hopefully.
The phone details are as [email protected]
HTC ONE X+
android v: 4.2.2
htc sense version: 5.0
software num: 2.18.401.2
htc sdk api level: 5.41
How can I make a full backup of this stock firmware so if I decide to go back after using some custom firmwares, I can do so by restoring it back.

- unlock bootloader
- install custom recovery (CWM/TWRP)
- nandroid backup (all partitions)
You can restore this any time you need. Don't forget, you have to flash the boot/kernel backup separately in fastboot from your pc, so copy that backup to your computer once you have it.
BUT: if you want to go completely back to stock (relocked bootloader) you also need to flash stock recovery. i don't know how to dump stock recovery... maybe you can find some stock recovery.img for your version number here on xda or via google.

nandroid backup = backup in custom recovery.
i mean if you want to restore your stock backup, you also have to flash the stock boot.img/kernel in fastboot because with S-ON phones we're not allowed to flash boot.img/kernel in recovery, hence we can't restore it using recovery restore function.
HTC ONE X+ RUU needed
Hi guys, i used to have a custom rom on my htc one x+ but now i want to put the stock RUU but i relocked and dicovered that my hboot is 1.40.0000 and my version-main is 1.17.401.3. So what can i do now?
Hello everyone,
I have a question. I have unlocked my bootloader, rooted and s-off my phone, but before thatI have backedup my original Rom. But one day I got encrypted problem, so I decided to restore the original Rom. My question is that I have an update to sense 6 but it can't be installed, so it's that because I s-offed my phone or there is any other reason.
P.s: I tried to relock the phone and the same problem happen.
When you unlock your phone, a few files in the data folder are deleted. To be precise it is the data preload folder. You need these for the ota. Which device do you have, euro ? What's your stock rom version?
How can I get these files have the international version. I'm on sense 5.5 android 4.4.2
Software up to date issue
HI all, just got this M8 and it is an ATT Version. but I believe it is unlocked because I am using it with cricket.
When trying to update Android Tells me software is up to date ?
Android version 5.0.2
HTC Sense Version 6.0
Software Number 4.28.502.1
HTC SDK API Level
I am pretty sure that ATT has updated to Marshmallow by now / So why can't I update? I am on wifi and 4G/LTE Could it be because I am using a Cricket Sim Card in the Phone ?
I have downloaded the RUU for Marshmallow software version 6.20.502.5. Should I continue with the Manual update ?
I believe this phone was originally purchased from ATT on May of 2016 if it makes any difference , figured I post it. since it could be a newer version of HTC M8.
Also is there a way to back up my current stock rom, without Rooting phone ? Thanks for all your help.
As I cannot root my phone, because when I go into developer option and search for S-off That option is not there and I can't Continue.

That is correct, the AT&t version (and most US versions) can only OTA update if connected to the proper branded carrier (AT&T in this case). Therefore, the RUU is your best option to update.
I have downloaded the RUU for Marshmallow software version 6.20.502.5. Should I continue with the Manual update ?
You can. But you need to flash the 6.20.502.5 firmware first, before you can flash the RUU. See instructions to flash the firmware here: https://forum.xda-developers.com/showpost.php?p=67123738&postcount=7
Then run the RUU. Keep in mind, that RUU will wipe the phone. So backup your data to an off-phone location (cloud, computer, etc.) before RUU.
Also is there a way to back up my current stock rom, without Rooting phone ? The current Lollipop ROM? No, there will be no way to revert to LP by official means, once you RUU to Marshmallow. I doubt you will find the need or desire to "downgrade" to obsolete LP version. If for some reason you did want to, there are options, but would require unlocking the bootloader (to install custom recovery and flash a Lollipop ROM), or s-off (which would allow you to "downgrade" by RUU - which is not allowed with s-on).
As I cannot root my phone, because when I go into developer option and search for S-off That option is not there and I can't Continue.
You are misunderstanding a couple things:
1) s-off is not a setting in Developer Options. s-off can only be obtained with sunshine app ($25)
2) You don't need s-off to root this device. Simply unlock the bootloader, install TWRP, and flash SuperSU to root

Two more Questions, Can I upgrade to an official DEV Edition RUU on this ATT Device? or would I have to use a Custom Dev ROM ? as I am trying to Tether with my phone, just like my official Developer HTC M8 I purchased in 2014 , Seems AT&T phone wont allow me to Tether ?
Also once I flash firmware and upgrade to official RUU will need to Unlock and Root Loader? Will doing upgrading to official Marshmallow Relock bootloader and Un Root Phone ? Back to Stock ? Thanks again, I will be attempting this pretty soon. Thanks again

You're welcome. Always happy to help!
Two more Questions, Can I upgrade to an official DEV Edition RUU on this ATT Device?
You can't flash the Dev Edition RUU with s-on. Even though the versions are very similar (same model ID - MID) the two versions have different carrier ID (CID). Wrong carrier ID will make the Dev Ed RUU fail, by definition. And the only way to change CID is with s-off. Further, its not really necessary to flash the Dev Ed RUU (and not worth spending money of s-off) to accomplish what you want (see more below)
or would I have to use a Custom Dev ROM ? as I am trying to Tether with my phone, just like my official Developer HTC M8 I purchased in 2014 , Seems AT&T phone wont allow me to Tether ?
Its correct that the AT&T stock ROM disables tethering. Flashing most custom ROMs (or the Dev Ed ROM) will enable tethering - as well as remove annoying AT&T branding and bloat apps. Flashing the Dev Ed RUU is not necessary to accomplish this.
Also once I flash firmware and upgrade to official RUU will need to Unlock and Root Loader? Will doing upgrading to official Marshmallow Relock bootloader and Un Root Phone ? Back to Stock ? Thanks again, I will be attempting this pretty soon. Thanks again
You need to relock the bootloader in order to flash firmware and RUU (command: fastboot oem lock). Once the RUU is complete, the phone will be on a fully stock "factory" image. So you will be unrooted. You will also be back to stock recovery (no longer have TWRP installed). From there, what you want to do:
1) Unlock the bootloader again. Either use the same unlock bin code you used to unlock BL before. Or get a new code from HTCDev.com
2) Flash TWRP back to the phone with fastboot. TWRP 3.0.2 is recommended for compatibility with MM firmware.
3) Flash the desired custom ROM. The custom ROM will be rooted (if you flash the Dev Ed ROM, you can select root in the AROMA installer).
For the Record, I have made a back up of my Lollipop via TWRK. I also backed it up using Titanium back up, just in case.
Always good to make backups. Although be aware, that RUU will wipe the phone, including internal storage. So if you picked internal storage as your backup location, you'll want to move/copy to another location (removable SD is okay, otherwise to computer or cloud).
Also note that restoring app data (as well as call logs, SMS) using Titanium, after RUU or ROM flash should be okay. But don't restore any system data, as this can cause problems.

I think i may have bricked my phone? I went and installed an RUU firmware file for Marshmallow as most instruct to do via Fastboot. All went well, installation completed and i was able to send command to phone to reboot. when it tried to reboot. white screen with HTC Comes on and then goes almost black with a very light dark grey background.
Phone would not reboot into anything but dark screen. even when i restarted it with power button. the only thing that worked for me, was Holding Down Power/Volume and quickly hit the volume down button before device would vibrate to reboot, that took me into recovery. Below is what i see in Recovery.

It's basically impossible for you to do anything with an s-on M8 that will actually brick it. That is the good thing about s-on.

I think you only flashed the firmware.zip and not the RUU. Based on the condition here, and your other thread you created here: https://forum.xda-developers.com/htc-one-m8/help/htc-one-e-m8-fastboot-issues-t3757628
I clearly described above to flash the firmware.zip then the RUU. They are 2 completely different things. Firmware is about 80 MB and only contains hboot, radio, and a few other things. RUU is a full image that is 1.5 GB.
No boot after flashing signed firmware is normal, as it expects the RUU to be run afterwards.

adb doesn't work in fastboot mode. Only fastboot commands will work in fastboot mode. You can only use adb when booted to OS (not an option for you, obviously) or alternately in custom recovery TWRP. So what you describe (adb not working) is normal and expected.
However, fastboot is enough to get the phone working from the described condition.
