Hi all,
I've created a simple guide to restore your HTC One M8 back to stock firmware while still being on S-ON.
This guide will provide you with all the files required to restore your EUROPEAN device back to stock.
If you have an device from another region, you'll need to find the RUU & recovery image yourself. (see below)
Prerequisites:
- HTC Drivers (just install HTC Sync and the included drivers, then remove HTC Sync)
- Fastboot package
- Stock recovery.img (you'll need the recovery.img with the same fw version as the RUU you're going to flash) (Link to 4.16.401.10 recovery.img for European non-carier devices)
- The RUU for your region/carrier. (Link to 4.16.401.10 for European non-carier devices)
If you have an USA /USA carrier device, go here for the RUU files
If you have an device from another region than Europe or USA, good luck finding the correct RUU
Look here to find recovery.img files for all regions (thanks to @exocetdj)
Because this guide is intended for S-ON, only the RUU for your region/carrier will work.
If you don't have an RUU or cannot find one for your region/carrier, S-OFF your device and follow this guide to restore your HTC One M8 back to stock. (thanks to @EddyOS)
After you've gone trough all steps;
- The red text during boot will be gone
- You'll have the stock firmware, system, recovery and boot.img
- Your bootloader will say "Relocked"
- Your bootloader will say "Software status: Official"
Let's start:
Step 1:
Start the RUU exe by double clicking on it, it will take a few seconds before it starts. After it has started, do not continue but go to your temp folder (type %TEMP% in your address bar)
Find the folder with the temporary files from the RUU (mine was called: {C48DBAA3-1CC0-4DF6-B069-B9CCB27F93C9})
Inside this folder there should be a few files and another folder with a long code as name (mine was called: {50F2F878-636A-496F-A7CB-544C067E0C4B})
Inside this folder, scroll down until you find rom.zip, open this file
Extract boot_signed.img and place it in a folder with the downloaded stock recovery and the fastboot.exe file
Now close the RUU installation wizard
Step 2:
Turn off your device
Hold VOL-Down + Power, after a few seconds you'll be in the bootloader. Now release the buttons
Navigate with the volume buttons to fastboot and confirm with the power button.
Step 3:
You should now have a folder with the following files:
- fastboot.exe
- AdbWinApi.dll
- AdbWinUsbApi.dll
- boot.img (extracted from the rom.zip)
- recovery.img (see prerequisites)
Inside the folder while holding shift, click right mouse and choose Open command window here
Before starting, it's recommended to rename the recovery file to recovery.img and the kernel to boot.img
Type the following commands in order (make sure to check the output and see if every command is successful before executing the next command)
Code:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot oem lock
This will push the stock kernel & recovery and relock your device.
Step 4:
Open the RUU installation wizard again and follow the instructions.
It will start flashing the RUU on your device.
After 8-12 minutes, the installation will be complete and your device will boot into system.
Step 5: (optional)
Power off your device
Hold VOL-Down + Power, after a few seconds you'll be in the bootloader. Now release the buttons
Verify that your bootloader says "Relocked" & "Software status: Official"
Congratulations, your device is back to stock again. After it's finished booting and optimizing 261(!) pre installed apps, you'll be greeted by the setup wizard on your phone.
If you have any questions, let me know.
Common problems:
Fastboot cannot find my device?
- try reinstalling the HTC drivers included with HTC Sync, and make sure to remove HTC Sync afterwards but leaving the drivers installed
I've got error 155 when trying to flash the RUU
- make sure your bootloader is locked. This tool only works when you have stock kernel, recovery and your bootloader is locked or relocked.

This is my phone , should i do any thing more or just the steps u mentioned???
I was told that i must upgrade my firmware, must i ??
Thanks
This is a great guide for those that just want to return to stock for their own purposes. However, this will not be enough for sending the phone into warranty, for that you'll need to take a few more steps with S-Off to get that RELOCKED flag to say LOCKED.

From my experience with HTC warranty repairs, they don't really care about the bootloader being 'relocked', S-Off is a more common cause for them to not repair the device.
But, above differs per repair center / per country

You are S-ON so you need to relock the bootloader and run the ruu.
If you want to give all info to work with you need to post the outcome of :
Fastboot getvar all
Delete the serial and imei and post the list here.
Or check the firmware & nand backup thread here in the general section. Restore the stock rom and recovery and perform ota updates which also will upgrade the firmware

Has nothing to do with where he bought it from, it is depending on the phones hardware & software, for all we know its imported.
The specs are important not where he got it from. And you can't tie it down on how repair centers handle the phones....that's a matter of good luck !

I bought it second-hand from Qatar if you mean country.
Hi. I tried to use this guide but it I couldn't follow it through. I have relocked, tempered, S-ON, CID : TMOB102 phone. It is stuck in the HTC logo after a full wipe from twrp. I don't have OS, and the main version is empty. So far I have tried all the European RUU which gave CID error and 2 T-Mobile RUU's with MID error both. Can anyone give me a suggestion?
Problem extracting boot_signed.img

Please check if your device is unlocked. You can't flash boot.img's while on a locked bootloader.

You are using the wrong command ! It's :
Fastboot flash boot boot.img
NOT
Fastboot boot boot.img ! That's why you got stuck. And indeed make sure the bootloader is UNLOCKED before you flash !
While i don't even know flashing the boot.img and recovery seperatly first is actually needed because all that's needed is to relock the bootloader and run the ruu.exe or the temp rom.zip via sd card.
afaik the ruu method takes care of the boot.img and recovery on its own.
Got a problem with 3rd command (locking oem) in step 3. It goes like this:

Now my phone is stuck on my ROM's boot logo and now I can't access bootloader.
EDIT:
I've managed to access bootloader by holding power + volup and then holding vol down. After that installing via RUU went smooth.
Hi, I followed your instructions, but before I could start with 4th device booted up and i accidentaly accepted upgrade. It rebooted and upgraded the device, and then stuck on boot screen. Now I try to update it through RUU but it says image version 4.16.401.13, and I can't find RUU for that version. Any ideas? Can I somehow reinstall twrp and restore nandroid backup?
P.S. in bootloader it still says software status: modified :/
P.P.S. I still managed to make RUU go through all the steps, from a billionth time. It would usually stuck on steps 0, step 1, or step 3. Now it seems like it's booting fine... Time to shower away all the cold sweat from my body.
Hi Guys,
I have windows 8.1 and can't open rom.zip file. I have an error : The compressed Folder is invalid. Installed winzip, 7-zip - can't go ahead.
If you are having trouble sending the ruu and you are stuck at sending 0/7 or 1/8 and only htc logo. then just delete htc sync manager from your pc!!!
Messed up few things and now need to revert back to stock. Looked through HTC dev site and cant' find any. Thanks.

You don't need to extract the zip. Rename zip to 2PZFIMG & copy to root of SD Card (2nd sim slot). Turn off the phone and enter download mode. Phone will detect the RUU file & confirm the flash.

On the gunmetal one I installed TWRP and rooted it, but being a noob I didn't fully update it first and now I can't take an OTA. My whole approach was wrong I think. I'd like to get the gun metal one back to stock and start again and was wondering if I could use the working one to do so. I did a lot of research trying various ways to back up the working phone:
Trying to boot CWM via fastboot boot so I could create a backup. Apparently this won't work on this phone.
Trying MTKDroidTools / SPFlash, but it seems the MTK6795 isn't supported with those tools
Using ADB to backup, but since my phone is not rooted it will not work. From what I understand if the phone is rooted and/or the root partition was mounted read/write you won't be able to take an OTA so this method wont work either.
Is there another method I am missing where I could backup my entire working phone to flash the one I messed up? I know RUU is a possibility but I'd really like to go this route instead as all most of the locations to download RUU's seem a bit sketchy. Should I even be concerned with this if I can find a signed RUU?
THanks for any help.

Do you have found an OTA.zip file?
I need it too, I have the same problem as you...

Hi,
if you're able to access the phone via fastboot, you can try the following method:
https://forum.xda-developers.com/u-ultra/help/howto-unbrick-ultra-t3891033
Greetings
Try this one:
2PZFIMG_OCEAN_NOT[email protected]80307_63.34_release_522808_signed_2_4 .zip
Rename the file to "2PZFIMG.zip" and place it in root of sdcard. Boot into download mode and confirm flash with volume+ button
Hey,
I think I have truly messed my device up - I was running another ROM for a while and wanted to return to stock. After many hours of stupid decisions, I am left with a phone that has no recovery or OS, and is bootloader locked. Here are my vars.

Any tips on what to do?
So I think I can install an OTA via the sdcard and download mode, however
(bootloader) version-main: 2.21.401.12
is stopping me. For some reason the version is higher than any OTA I can find?! I know there is a tool to change this version, however it relies on adb (and I think root).
