Preliminary steps
1. Make sure that your phone is always charged above 50%!!!
Running out of battery in the middle of flashing something could brick your phone.
2. Make sure that your computer can properly communicate with the device:
We will be issuing commands to the phone from your PC via the USB cable using Android’s SDK tools, in particular
ADB and
fastboot. If you have not done so already, you must install the following on your Windows computer for this to work:
- Java runtime
- The Universal Android ADB Driver for Windows.
- ADB & fastboot
You can verify the connection between your PC and phone by running the following procedure:
A. With the phone booted normally, connect it to your computer with the USB cable.
B. Enable Android debugging by going to
Settings > About phone and tapping on “Build number” 7 times.
C. Go to
Settings > Developer options and check “Android
debugging”. A dialogue box will appear asking you to authorize your
computer’s RSA fingerprint. Click “Always allow...”
D. Open a command prompt in Windows and navigate to the folder where you put (ADB & fastboot) above.
E. Type the following command:
You should get a return like this:
If you cannot get the connection to work:
1. Check your USB connection, then verify that Android debugging is
enabled in settings and that your computer’s RSA fingerprint has been
authorized.
2. Still not working? Open Device Manager in Windows and make sure that
you don’t have a yellow exclamation point next to something like
“Android Device” or “One.” This would indicate a driver problem that
must be resolved. Try re-installing the Universal Android ADB Driver
for Windows, and make sure to restart your computer. Once you’ve
rebooted, if you still have a yellow triangle, right-click on the device
and select “Update Driver Software,” then “Search automatically for
updated driver software.”
3. If you still have a yellow exclamation point, then try forcing the driver to install:
- In Device Manager, right-click on the device and select “Update Driver Software.”
- Select “Browse my computer for driver software”
- Select “Let me pick from a list of device drivers on my computer”
- Select “ADB Interface” from the list
- Select manufacturer “Google”
- Select “Android Testing Interface Version xxx”
- Click “Next.” If you get a warning, select “Yes” to continue and wait for the driver to install properly.
3. Know how to enter “fastboot mode” on the OnePlus X
To root the device, you must be competent at booting it into fastboot mode. There are two ways to accomplish this:
- Power
off the phone. Then simultaneously hold down the volume up & power
buttons until it vibrates. When done correctly, you will see the words
“Fastboot Mode” on a black screen. If not, you dumb-thumbed it, and the
device will boot normally into Android. Power off the device and try
again.
- With the phone running Android normally and Android debugging
enabled (see above), open a command prompt in Windows, navigate to the
folder where you installed (ADB & fastboot) and type:
Code:
adb reboot bootloader
Rooting the OnePlus X
There are three essential steps to rooting the device:
- Unlock the bootloader
- Flash or boot into TWRP custom recovery [For OxygenOS 3.1.3 use TWRP blu_sp★rk r175]
- Flash SuperSU...zip from recovery [For OxygenOS 3.1.3 use SuperSU v2.78 SR1 beta]
However, we're going to add a few more to protect your data and device in case something gets borked.
1. Backup your phone’s data
Unlocking the bootloader will involve doing a factory reset resulting in
the loss of all accounts, emails, texts, apps and app data, pictures,
music, etc. on the device. Move anything you need to keep onto your PC
or a cloud service like DropBox.
2. Unlock the bootloader
2A.Go into
Developer Options and enable bootloader unlocking
2B. Boot the device into fastboot mode. (Simultaneously hold down
the volume up & power buttons until it vibrates.) You should see a
black screen with the words “Fastboot Mode”.
2C. Plug in the USB cable.
2D. Verify that your device is connected with this command:
You should get a return like the image above under Preliminary Steps
2E. Unlock the bootloader using the following commands:
Code:
fastboot oem unlock
The device will unlock the bootloader, erase all user data and
reboot itself into Android. You will have to set up everything from
scratch.
3. Re-enable Android debugging
3A. Re-enable Developer options by going to
Settings > About phone and tapping on “
Build number” 7 times.
3B. Go to
Settings > Developer options. Check “
Android debugging” and re-authorize your computer’s RSA fingerprint.
4. Download SuperSU zip
NOTE: For
OxygenOS 3.1.3 use
SuperSU v2.78 SR1 beta
Copy
UPDATE-SuperSU-v2.XX.zip to your phone’s SD card.
5. Flash TWRP custom recovery
5A. Download
TWRP recovery.
NOTE: For
OxygenOS 3.1.3 use
TWRP blu_sp★rk r175
5B. Place file you downloaded above to the location where you installed SDK tools (ADB & fastboot).
5C. Boot the device into fastboot mode and connect it to your computer with the USB cable.
5D. In this step, we will replace your stock recovery with TWRP recovery.
Note: This step is optional. If you want to root but preserve stock recovery, skip straight ahead to step 5E below.
Open a command prompt in Windows and navigate to the folder where you
installed SDK tools (ADB & fastboot). Type the following commands:
Rename :
twrp-3.0.0-0-onyx to recovery.img *[important]
Code:
fastboot flash recovery recovery.img
5E. Reboot into TWRP recovery with the following command.
Code:
fastboot boot recovery.img
You should now see the custom recovery you just flashed, not the stock recovery.
6. Backup your stock ROM before making any changes
In TWRP press “Backup.” <--- See how simple this is???
Don’t be a noob—backup your device!!! Right now we don't have stock
boot debuggable image files for the OnePlus X, so borking your device
could leave you with a nice paperweight until we do. 
Restoring from a backup in recovery is easy, and only works if you've backed-up first
7. Root the device
7A. The device should still be in recovery from step 6 above. Go back to the main menu and press “Install,” find
UPDATE-SuperSU-v2.XX.zip on the SD card, then flash it.
7B. Reboot the phone. It is now rooted!
7C. Go to the app drawer and open SuperSU. Update the binary if prompted. Its icon looks like this:
7D. Download and install
Root Checker from the Play Store to verify that you have root access.
Note:
If any link is not working then P.M ;)
