How To Unlock Bootloader of Nexus 9 and Root it

Nexus 9 is the latest Flagship tablet from Google, one of the most awaited and most demanded tablet of this year was finally available for both developers and Users. As anticipated, it won’t take long for anyone to root the device, unlocking bootloader is a piece of cake, but no one actually thought that it will be Chainfire himself that will root the device at the first place. For all those who are wondering who is Chainfire, he is the genius behind the Rooting method, both the Super SU and CF-Auto Root is the invention of this person. Well Nexus 9 was available only a few days ago, and today on the XDA the rooting method is available for Nexus 9 along with the bootloader unlocking script, which is by far the same for all the Nexus devices.

You are going to unlock the bootloader sooner or later, so don’t make my type of Mistake and unlock is right now while your device is still empty and you don’t have much data in it. I unlocked the Bootloader of Nexus 5 when it was full of data and it was such a sad moment for me, despite that I had a back-up of all my data. Rooting is your choice, whether you want to do it or not, but it is not that difficult, you should give it a try. We are not going to use CF-Auto Root for rooting, because for now, the 64-bit firmware is not supported, we are going to use the Old Super SU method, which might brick your device, so if you are not sure or not ready to do this, back off and do something else, you just can’t because there is nothing to do instead checking out this device. Without further ado, let’s continue towards the method.

Early Preparations:

1. This is only for Nexus 9!

This custom ROM is only for the device mentioned above. Make sure that your model number matches the one listed above. To do so, go to Settings > About Device on your device and see your model number. Flashing this ROM on any other device will result in bricking it so make sure that you meet this requirement first of all.

2. Battery should be charged at least over 60%

Make sure that your battery is charged enough to complete the flashing process. In case your battery is low and your device goes dead during the flashing process, you may end up soft bricking your device as it won’t complete the flashing process.

3. Backup everything!

Just to be on the safe side, you may consider backing up each and everything from your Android device. This is highly recommended so that in case anything goes wrong, you still have the access to all of your data and you can restore it immediately. You may backup everything as listed below.

4. Disclaimer

The methods involved in flashing custom recoveries, roms and rooting your phone are highly custom and may result in bricking your device, and has nothing to do with Google or the device manufacturer that is Google in our case. Also rooting your device will void its warranty and you will be no longer eligible for any kind of free device services by the manufacturers/warranty providers. Incase of any mishap we may not be held responsible. Follow these instructions to the letter to avoid any mishap or bricking. Make sure that whatever you do, you are doing it at your own responsibility.
