I have been trolling various threads here at XDA to no avail. I successfully rooted my phone usinf clockwork mod, cyanogen 11. I needed to return it to its stock factory state. I found a very good article that instructed me to do the following:
How To Restore The HTC One Back To Stock Firmware
Let’s face it. At one point or another some of us root our Android devices, and in doing so we may realize that we either want the default experience back on our device or we have to take our devices in for repair, and we obviously cannot take them back rooted, so I’m going to show you how to unroot your phone and put it back to stock. Let’s get started.
DISCLAIMER: YOU ARE RESPONSIBLE FOR YOUR ACTIONS. NEITHER GEARPOP NOR I WILL BE HELD RESPONSIBLE FOR YOUR ACTIONS, YOU ARE DOING THIS AT YOUR OWN DISCRETION.
If you need help or this does not work feel free to reply below in the comments section, and I will do my best to help you.
Prerequisites:
HTC One
A Micro-USB cable, I recommend use of the OEM cable.
A Windows computer
HTC Stock Rom (For Sprint: http://www.androidfilehost.com/?fid=23203820527945238), Other Models: http://htconeroot.com/htc-one-stock...for-htc-one-attt-mobileunlockedinternational/).
ADB and Fastboot (http://forum.xda-developers.com/showthread.php?t=2317790).
HTC ADB and Fastboot Drivers: (For Windoows 8: http://forum.xda-developers.com/showthread.php?t=2232799, For Windows 7: The Windows 8 drivers should suffice since the folder says Win7 in it’s title). 64-bit only. If you need 32-bit please try looking elsewhere by googling “HTC One 32-bit drivers for Windows (insert version name here).”
Steps:
1. Connect the HTC One to your PC via Micro-USB.
2. Enable USB Debugging by going to your Settings app, tapping “About phone,” and then tap “Build Number” repeatedly, until it says (“You are now a developer!”).
3. Install the HTC ADB and Fastboot drivers listed above in the prerequisites section.
4. Install Minimal ADB and Fastboot, which is listed above. To install, just keep clicking “Next” until it’s done (if you want a shortcut created, make sure you have “Shortcut on Desktop” checked).
4. Download the rom zip for your device as listed above in the prerequisites.
5. Open Minimal ADB and Fastboot, and you should see a command prompt window open, with your device connected type “adb devices”, and your phone’s serial number should appear along with the word fastboot.
6. Next type “adb reboot-bootloader” to boot into the bootloader of the device.
7. Extract the rom.zip file from the zip file download above and place it in the location in which adb and fastboot are stored.
8. Now type “fastboot oem lock,” followed by “fastboot oem rebootRUU,” (enter the second command after it reboots to the bootloader) and you should be presented with a black HTC screen.
9. Type “fastboot flash zip rom.zip,” and you should be presented with an error code, that’s fine. Just enter the command again and hit enter, and it should flash. Make sure the phone is in RUU mode (black screen) each time you enter the command.
10. When it says “SUCCESS” and the green bar appears stuck, simply enter “fastboot reboot” in the command prompt. Your phone should reboot and you will be presented with the HTC setup screen!
It locked up at step 9, and now it will not do anything but boot in fast mode. I cannot get minimal adb and fast boot to recognize my phone ant more. Please help, I am completely at a loss.
Thanks in advance

Sorry but I think you´re in the wrong section here. this is the Moto G 2014 (titan) thread. So it should be moved to the Moto G 2015 section. Or, as the process is similar, the thread could be renamed.
Also it should be posted in Q&A, Help & Troubleshooting not in Andoid Development.
Everytime I have to unlock,flash recovery and root I can't remember how to do it....
So I'm writing this very easy guide.
First off get the One X drivers from here:
https://forum.xda-developers.com/showthread.php?t=2217384
These are old drivers as HTC have stopped including them in HTC Sync.
Download Android SDK Slim from here:
https://mega.nz/#!8tETTbga!iVOYHGwT7SYV9s9AKqT6hukX-odb7PNuQCrX6zJxpwQ
Unzip it anywhere you like, desktop's easy but it can be anywhere...
Go to https://www.htcdev.com log in click on Get Started then Unlock Bootloader and choose All Other Supported Models from the dropdown.
Click Yes and Tick the two boxes for all the legal stuff.
Now go into your One X Phone Developer Settings and switch on USB debugging.
Next go to Power settings and switch off Fastboot.
Then connect the phone to your PC via USB cable.
Allow your PC to recognise it and download any stuff it wants to.....
Go make a cup of Tea while this is happening.
Next go to your SDK folder, wherever you ended up putting it, click through to the Platform Tools folder where you will see ADB and Fastboot.
Hold down Shift and Right Click anywhere in the folder, choose Open Command Window Here.
In Command Window Type: adb reboot bootloader
Your Phone will boot into Bootloader
Keep the Command Window open...from now until the very end!!
That has just skipped all the 4 Steps on the HTC Dev site!!!
Proceed to Step 5
Now in the Command Windows Type: fastboot oem get_identifier_token
You will see a long block of text. Copy and paste this text into the the token field on the HTC Dev site. Right Click choose Mark and highlight the square bit of code then press Enter to copy.
Paste that into the My Device Identifier Token
HTC will email you a little Unlock_code.bin file within seconds (Check your Junk folder)
Then copy or move the token to the Platform Tools folder.
Back to your Command Window which should still be open!!
Type: fastboot flash unlocktoken Unlock_code.bin
Now follow the instructions on the Phone....
The phone will Unlock the bootloader....
And Reboot your phone....
You need to go back to settings and switch on USB Debugging and switch off Fastboot (See start of tutorial)
Make sure you are still plugged into your PC
In Command Window Type: adb reboot bootloader and your phone will go back into the Bootloader screen.
Next go here: https://twrp.me/Devices/HTC/
Choose your One X and download an early version of TWRP as the newer ones need the old ones to be installed!!
The One X comes in different flavours so make sure you get the right one for your model....
For sake of argument say I downloaded this file: twrp-2.4.4.0-endeavoru.img
Place that file in the Platform Tools folder
Then in Command Window type: fastboot flash recovery twrp-2.4.4.0-endeavoru.img
This will install your TWRP Recovery!!!
Excellent...now you can unplug from your PC and boot into Recovery.
In TWRP select Reboot and it will ask you if you want to install SuperSU.
You do, swipe the screen and your phone will Reboot into the Operating System.
From there open the Super SU app and update your Super User Binaries...
And that's how to Unlock the Bootloader, Install TWRP Recovery and Root....
EASILY!!!!

Hit Thanks if its Helped You!!
Not being an Android-Expert, it wasn't quite obvious for me how to unlock the bootloader of the FP4. Although there is an official guide from Fairphone on how to prepare an FP4 to be able to unlock the bootloader, the crucial part to actually unlocking is missing. Perhaps it's obvious to the average Android-Enthusiast, but for me it certainly wasn't ;-)
This guide shows how to unlock the bootloader of a FP4, as it is intended by Fairphone. So it's kind of official; yet I'm not related to Fairphone.. I just own a FP4.
1. Backup personal data
Unlocking the bootloader will also do a factory-reset of the phone. So a backup of personal data is required.
2. OEM unlocking
"OEM unlocking" must be enabled for unlocking the bootloader. There is an official guide on how to enable "OEM unlocking" for FP3 and FP4:
Bootloader Unlocking Code for Fairphone 3 - Fairphone
Instructions on how to unlock the bootloader of your Fairphone 3.
www.fairphone.com
Just follow through the guide an come back afterwards.
3. Prepare USB-Debugging
Connect the phone via USB-Cable to a PC and enable "USB-Debugging" under Settings->System->Advanced->Developer options.
On the PC you need the Android SDK Platform-Tools ('adb' and 'fastboot' command), which can be downloaded here:
SDK Platform Tools release notes | Android Studio | Android Developers
Android SDK Platform-Tools is a component for the Android SDK.
developer.android.com
If everything is setup correctly you can open a terminal and run the following command:
adb devices
It should print out something like:
abc123 device
4. Actually unlocking the bootloader
Run this command to restart the phone and get in fastboot mode:
adb reboot bootloader
Your phone will shutdown and then show a screen which says at the bottom "device statue - locked"
Now, the bootloader can be unlocked with the following command:
fastboot flashing unlock
Follow the instructions on the phone-screen and the phone's bootloader will finally be unlocked... also a factory-reset will be done, thus deleting all personal data.
I wish I had this guide, when I got my phone, so I hope it can now be helpful to someone else
i have leared calyos has a builtin bootloader unlock. they make it super painless.
I had to unlock my bootloader on my old but trusty G20, had it grayed out. This is often normal on relatively new android devices. 1. Finish your setup wizzard normally, 2. Connect To Wi-Fi,. 3 Have it grab signal from his rild or modem. 4. Then open developer settings and go on adb shell to type adb shell reboot bootloader... then just type fastboot devices followed by fastboot flashing unlock on your phone press power down and wait (make sure the device does not have FRP set to ON if it´s on boot again and remove your Google´s Account). Done, now you can do a fastboot reboot and finish the setup wizzard again, go into dev settings and you will see "Bootloader is alrredy unlocked". (The order on the steps is key to make it work) reasoning is quite simple, you should not be unlocking a bootloader of a device that you don´t own, hence finishing the propper setup first should give you the best result, set no google acccount and no security (you are going to wipe the device again when you unlock the oem). Just bringing this up if it helps someone unbrick or fix their G20 (good device even for UNISOC).
