Do you want to unlock the OnePlus 5T bootloader? If you want to gain further control over the stock Android firmware, you should follow and apply the steps from below. During this guide we will discuss about the advantages and about the risks implied by this unlocking process, we will detail the essential pre-requisites and in the end we will explain the actual unlocking operation that’s compatible with the new OnePlus 5T.
The bootloader is a small program that runs on your OnePlus 5T. This program will run each time a boot or a reboot is initiated and will load the Android OS and other essential start-up programs without which your smartphone cannot function correctly. So, this program cannot be removed from your device as it has one of the most important roles within the Android core system. What you can do is to unlock it in order to get rid of some annoying factory and default restrictions.
These built-in restrictions are there to limit your access towards the Android OS that runs on your OnePlus 5T. Thus, if you will want to tweak your device you won’t be able to do it unless you first unlock the bootloader. And that’s what we are going to do in this guide – preparing your smartphone for further customizations and optimizations.
In a few words, once the OnePlus 5T bootloader will be unlocked you will be able to apply different other custom operations – and here are a few examples in that respect: gaining root access, installing a custom recovery image, adding a custom kernel, flashing a custom MOD, removing bloatware, installing apps from other sources than Google Play, overclocking / undervolting CPU frequencies and further more.
As you can tell, OnePlus isn’t supporting the unlock process – in fact unlocking the bootloader is an unofficial operation which can void the warranty of your OnePlus 5T. Note: the only way in which you can try to restore the warranty will be by reinstalling the stock Android firmware – in that case the bootloader will be relocked and your phone restored back to its initial / default state. Anyway, what’s important is to keep everything safe and secured in order to avoid any possible unpleasant situations.
And, in that respect you should initiate a full backup for saving your personal files – in some situations, while the bootloader is unlocked your data might get corrupted or even wiped out. Therefore, you must be sure that everything that you might still have to use afterwards is placed in safe hands. So, before doing anything else consider in using built-in cloud storage platform or to sync your files with your Google Account. As a backup and restore alternative you can also go to Google Play and download compatible and already tested apps.
A computer will be needed during the steps that are described below. On this computer you need to install your OnePlus 5T drivers and the Android SDK toolkit – for getting and setting up Android SDK follow one of these tutorials: learn how to install Android SDK on Windows or learn how to set up ADB on MAC OS X / Linux.
On your smartphone, before unlocking the bootloader, become a developer – you can enable Developer rights with ease by tapping repeatedly on Built Number (keep tapping on this field until the ‘you are a developer’ message is displayed). Then, go to Developer Options (you can find this entry within regular Settings) and from there check the USB Debugging option and the OEM Unlocking feature.
Charge your OnePlus 5T before starting to unlock its bootloader. It’s important to ensure at least 60% power as otherwise your device might get out of juice right in the middle of the unlocking process – a sudden shut down might cause different and severe software related issues within the Android core system. So, if required plug in the charger before doing anything else for avoiding unpleasant Android problems.
Don’t forget one thing: the steps explained below are compatible with the new OnePlus 5T. So, apply this tutorial only for this particular Android based device as otherwise you can easily end up in soft bricking your smartphone or tablet.
