​This is a tutorial on how to return your Galaxy Nexus to stock if needed. This method uses the official images from Google
I am not to be held responsible if anything goes wrong when attempting this. This includes bricking your phone, flashing a bad image, causing WW3 etc. I am also not responsible for any files in this tutorial. They were all provided by other people.
There may be inaccuracies in this post that may lead to various things such as bricked devices so be warned. Let someone check it over first! If you see anything wrong, let me know and I will edit it!
What you need

DOWNLOAD
1) Take a Nandroid Backup if you have CWM installed
2) Extract the content of the Google Image
3) Copy the contents of the Fastboot download to the same folder as where you extract the Google Image too.
4) Boot your phone into the Bootloader mode
5) Open up Command Prompt or Terminal, navigate to the folder you've extracted it all too and enter the following commands waiting for each to finish
Windows
fastboot-windows flash bootloader bootloader-maguro-primekk15.img
fastboot-windows reboot-bootloader
fastboot-windows flash radio radio-maguro-i9250xxkk6.img

Anyone other than the OP try this yet? If so, what state were you starting from (cwm installed, which custom rom etc) and did it work? did you need to do anything differently?

It works, can confirm!!
1. copy the extracted rom folder to clockworkmod\backup\maguro_4.0.1 on your internal storage
2. boot in too cwm
3. (what i do) in mount and storage menu, format system/data/cache
4. install super wipe lite zip file
5. restore the maguro_4.0.1 rom
phone boot up, everything fine, first run wizard start..
6. reboot to fastboot
7. flash the stock recovery "fastboot flash recovery recover.img"
8. boot in to recovery to test
9. reboot the phone
i didnt lock the bootloader while i will only root the device and other things let on stock.
i came from unlocked bootloader, clockworkmod recovery and android revolution hd rom..

Brilliant news.
I've updated the tutorial to include the latest updates

Even on a jailbroken iPhone, when you do a factory reset you get all your settings reset but the phone is still jailbroken.
Same thing applies with Android. You need to flash the stock files to get back to stock.

@evostance
Another possibility (as yours relies on having access to a backup/nandroid as well as somehow being able to access the SDCARD partition) which some people may not have
would be Peter Alfonsos "return to stock"way

flash it via fastboot and you are golden
All you need is fastboot and the image

you don't need a pc to flash a rom, you just need it to transfer the rom itself on the sdcard... go into recovery, mount usb and that's it...it should work

Well now the problem by not being able to access sd is fixed, but i thought you need to do the commands Fastboot flash boot.img and Fastboot erase cache to install a new rom?

Yes, you have to flash new rom after a full wipe in recovery, boot into fastboot usb and use this command for flash the boot.img

Did you install HTC syncmanager ? If so uninstall it but leave the drivers on the pc !
Then put the phone in the bootloader and check if you see there

It does say fastboot usb, but commands doesnt work. HTC sync not installed and have tried to install drivers manually, through sync and through exe file. Still says device not found and device manager says drivers are outdated

Go into the device manager, update driver but pick the supported device from the list (don't pin me on the exact way as im not on the pc to check now) select the android phone from the list and install it (or at least update it)....

Good, you might want to consider updating your hboot. That might solve some issues. The 1.28 contains some bugs.
It may have also something to do with jellybean because they removed usb mass storage in there. Only mtp is available.
The latest custom JB roms (at least some) are supporting usb mass storage again

You can obtain your 1.39 hboot firmware update here
http://forum.xda-developers.com/showthread.php?t=1957376
Its the first one in the OP.
Put the file in the fastboot folder and rename it to firmware.zip
Then put the phone in the bootloader and relock it
Fastboot oem lock
Then flash the firmware with these commands
Fastboot oem rebootRUU (watch the capitals, this command will reboot into a black screen with a silver HTC logo)
At that point you flash the firmware
Fastboot flash zip firmware zip (if it fails the first time, don't worry....just repeat the command until it says oke)
Then unlock the bootloader, reflash the custom recovery and install a brand new JB rom of your choice !

Unrooting International One M8

Hi.
I've got an HTC One M8 and would like to get everything back to stock, but have been experiencing a bunch of issues.
The phone was stolen a couple weeks ago and I got it back yesterday. The person installed Android 6.0.1, ClockworkMod 6.0.4.8, Turbo, Viper and I've found a com.cyanogenmod.eleven folder on the SD card (not sure what it is though). I've tried doing everything by following "How to Unroot the HTC One M8 Complete Guide" by the Unlockr on Youtube (can't post a link since I'm new) , but I've been running into problems.
I can't connect the phone to a PC. I've checked Device Manager - it recognizes the phone as an Android Phone and it seems to think that it's a CD ROM.
My version-main is blank, and my cidnum is 02___102.
I've managed to get to Recovery but I get "md5 missmatch" every time i try to run it. There isn't a nandroid.md5 file in any of the backup folders.
Could someone please help me get my phone back to an out of the box state? I'm not a pro, but I'll be able to follow instructions.
Thanks.

Easiest way would be a RUU. Just find one that matches your Cid and you're good to go

Thanks dude, but could you elaborate a bit?
I found a collection of M7 RUUs but can't seem to find them for M8. What does the process look like, as in what should I do after I find the correct RUU?

I don't have the time right now, but I'm sure that there's many guides in the general forums about how you can return 100%to stock

Can you get to the bootloader ?
If possible, post here fastboot getvar all result without serial & imei no.
Need to confirm your current firmware version base on these getvar details because your version-main is blank before we can advise whether to use RUU or non-rooted stock nandroid backup to restore

Here's the getvar image I got when I tried to unroot the phone a couple days ago. If it's missing anything important I'll do it again. And yes, I can get into bootloader and recovery.

Great.. your firmware is 4.20.206.1
I'll give you link to RUU in half an hour when I'm home.
Meantime you may want a different method, restore non-rooted nandroid backup and its stock recovery then do OTA. You can read my thread linked in my signature.

Here is the 4.20.206.1 RUU.exe : https://www.androidfilehost.com/?fid=95916177934555499
and you need PC with USB2.0 (don't use USB3.0 or any USB hub) and the latest HTC USB drivers -
http://forum.xda-developers.com/showpost.php?p=64926362&postcount=4
As your device is S-On, you need to relock the bootloader.
Put your device on bootloader/fastboot mode and connect to PC.
Open a command prompt from your fastboot/adb folder, run these commands to relock bootloader
fastboot oem lock
fastboot reboot-bootloader
right click the RUU.exe and select run as administrator, follow the instructions accept, next, next, update & blalblabla until it finish.
Lates you can check for OTA and update the device to the latest Marshmallow. I believe there will be two OTAs.
Note : this procedure will wipes everything on your device and give you out of the box state phone.

Ok, so here's a bunch of questions. Bear with me, please
1. The RUU link takes me to a blank page, I guess it's down or something.
2. When I run the adb installer and choose to install the drivers it asks me if I want to install Samsung drivers. Is that how it's supposed to be?
3. Is it necessary to uninstall HTC Sync Manager? If so, how do I leave the drivers?
4. Do I need to put the RUU in a specific folder or can I run it from wherever I downloaded it?

2. Choose Y to install it system-wide but N for the drivers. You can open command prompt anywhere that you like even from desktop, the adb/fastboot work.
3. Yes, uninstall HTC Sync Manager, the installer will install Htc Sync Manager, USB Drivers and some microsoft needed runtime (separately). When you uninstall HTC Sync Manager, it will uninstall HTC Sync Manager only.
4. Anywhere that you like ... put on desktop for easy access.

So, I finally got the link to work and got everything set up, but I noticed that there's an O2 in the name of the RUU. I believe O2 is a carrier and my phone had no carrier when I bought it, I just wanted to check if that could be an issue before I do anything.

You wrote on your post #1 "My version-main is blank, and my cidnum is 02___102" and your getvar all show cidnum O2__102 ... that means your device is an O2 variant.
I believe it is SIM unlocked, so you can use any SIM on it. Being an O2 device, you can only run O2 RUU and installing RUU won't relock the SIM unlock.

I'll make sure to donate when I get some extra cash, and if there's anything else I can do for you do tell. Thank you for bearing with a noob like me!

So what did you try to do? The above doesn't tell us anything you tried or didn't try (aside from removing the SD card).
Don't want to waste the time and effort, to advise you to do things you may have already tried.

Hello,
Thanks for the reply!
I tried to connect it to my mac via usb to flash a rom or twrp etc but my computer doesn't show the phone.
I tried selecting the recovery mode from the menus and nothing happens.
It just restarts and goes back to the same mode.
So honestly i havnt tried much as i do not know where to begin.. Apart from going into all of the menus on the screen and that's it.
I think i the phone is missing the recovery and the rom? Not sure.... Help!

The mac will only be able to connect via fastboot, in the current condition. Do you have fastboot/adb setup on your mac? I'm not a mac user, so I won't be able to advise much on that.

Since the phone will only boot to bootloader, you are correct in that it appears the ROM is damaged or corrupt. Since I don't think the Rogers version has RUU to recover, you are right in the approach of flashing TWRP and ROM to the phone.
However, you will also need to unlock the bootloader, in order to flash TWRP. And you will need working fastboot connection to mac/PC in order to unlock bootloader and flash TWRP. So you really need to troubleshoot the connection issue, first.
You might also read through the following thread for more recovery options or info: https://forum.xda-developers.com/showthread.php?t=2694297

On post #1 OP wrote (few other lines) which is important to be highlighted. Without OS info no way to help.
Or as usual need fastboot getvar all result. If it is Lollipop RUU 4.20.631.3 is available for free.
Also I remember Marshmallow RUU is available too on AFH but can't confirm it now as I maybe wrong ..need to search for it
Edit : here is Marshmallow RUU - http://gsm-firmware.com/index.php?a=browse&b=file-info&id=14070
Leave it to you to guide OP.
Maybe need to flash 6.13.631.7 firmware first before RUU

Thanks!
I just tried the add fast boot connection went through all the steps ok, HOWEVER when i type in ./adb devices it does not show the phone. So far all posts and videos i have found explain about trouble shooting when the phone OS is still running but none for my situation.
There is a red highlights text which says "FASTBOOT"
and it turns to "FASTBOOT USB" when i plug in with my MAC
Also i have tried 2 different USB cables same result, tried clicking on the "REBOOT FASTBOOT" as well same result.
Anything else i can do to have a working connection ?

Have you installed the HTC drivers to your computer?
If not, install HTC Sync Manager (you can get the MAC version here). During the installation of Sync Manager the drivers will be installed. After they are, Uninstall Sync Manager (it doesn't play nice with ADB/fastboot) and the drivers will remain

When on fastboot, correct command is fastboot devices or ./fastboot devices
Based on your bootloader screenshot, you can try the above linked RUU to fix your phone

This is working normally, and as intended.
adb and fastboot are related, but different conditions, usage and requirements.
adb: Only works in OS, or alternately TWRP. Needs debugging enabled in phone settings. Will not work in fastboot mode.
fastboot: Only works in fastboot mode. Does not require debugging enabled in phone settings.
Stuck in fastboot mode, you should get a response (phone's ID) to: fastboot devices
Otherwise, there may be a driver or USB connectivity issue.
However, since ckpv5 linked an RUU for you to use, the mac won't help you. RUU is probably the easiest way to get the phone back up and running. But you'll need access to a PC for the RUU to work. RUU won't work properly with mac, even emulating a PC.

Nice. :good: Obviously, I missed that detail. Should have figures, since most M8 versions without "official" released RUUs seem to get them leaked as zip format.

Disclaimer: I am not responsible for any damage that may or may not occur. I do not anticipate any harm, use at your own disclosure.
Ever since the HTC U11 you cannot gain permanent S-Off, it is unknown if this will ever change. Due to this you must relaunch the Sunshine app every time you want to modify your CID. If you follow this guide to a T, you will understand the process and understand the limitations.
Your Sunshine license is tied to your phone's hardware and cannot be transferred to another device.
You cannot change a Dual Sim to a Single Sim device and vice versa.
Whatever new region CID you switch to, you must have a matching MID.
If you ever relock your bootloader, you must revert back to your original CID before doing so.
You may lose or gain WiFi Calling and VoLTE Features depending on the CID. Flashing LeeDroid Magisk Rom will enable the features on any CID. Your Carrier must still support them!
Requirements:
Properly setup ADB and HTC drivers, enable Developers options, USB debugging
Unlock your bootloader, install TWRP and root with latest stable build of magisk.
Use without a phone case to have access to sd card slot and Vol. up button
32GB or less, micro SD card
Good quality USB cable, preferably OEM
Funds to Purchase a license to use the Sunshine app
RUU of the CID you want to change to
Connect your device to your computer and startup the terminal. Use
Code:
adb devices
to see if your device is recognized.
Reboot to download mode by using
Code:
adb reboot download
, you device will reboot in download mode then use
Code:
htc_fastboot getvar all
and note down your device's information.
Once you got your CID and MID information, locate the CID you want to change from this spreadsheet and make sure they having matching MID. Then download the appropriate RUU.
Rename the RUU to 2Q55IMG.zip and place in the root of the 32gb micro SD card.
Visit official sunshine website and download the Sunshine app from the download section. Install the apk, run the compatibility test in sunshine and once confirmed compatible buy a license.
Launch Sunshine and read the instructions, it will send your device in download mode with temporary S-Off.
Connect device to your computer and open the terminal. Use
Code:
fastboot devices
to make sure your device is detected in fastboot.
Use
Code:
fastboot oem writecid
with your desired CID at the end. Do not reboot! Example:
Code:
fastboot oem writecid HTC__626
On your device's Download Mode Menu select Reboot to Download with the Vol. buttons and press power button to initialize. You will now have your desired CID and your device should still say S-Off. Do Not Reboot!
Insert the SD Card and on your device's Download Mode Menu select Reboot to Download with the Vol. buttons and press power button to initialize. Your device will now be prompted to press vol. up to use the RUU on your SD Card.
Your device will erased,formatted and converted your new CID. You are done!!
Setup LeeDroid Magisk Rom to enable Wifi-Calling and VoLTE options.

Thanks for writing this guide up man, I know it's only preliminary at the moment but I'm sure myself and many others will appreciate it.
Once I get home tonight I think I'll be changing my CID so I can finally get my bloody phone on Pie!

Ok I've hit a stumbling block.... S-OFF just fine and manged to change the CID in command line however when I go to type "fastboot reboot download" I get the following error "fastboot: usage: unknown reboot target download"
Luckily I just changed my CID back to my standard one, reset the phone by "fastboot reboot" and away I went again. But still obviously on my stock CID.
So I tried again, this time changed the CID and selected Reboot to Download in the Download mode menu itself and that worked a treat. So here I am now running on my new CID!
Your guide was awesome, thank you. Just thought you might want to amend that little step unless I've done something wrong or am using a different fastboot version thank yourself

Not a problem, thank you for putting the guide together!
Not sure about root yet, I ran out of time but from looking around it seems installing Magisk is a bit different due to TWRP not working properly. Not sure if you want to include that in the guide as well?

single sim us unlocked bootloader rooted with magisk on pie
