How to Unlock Bootloader on Razer Phone

Razer Phone debuted as a new and enthusiastic project. As the name suggests and as the brand promises this is a gaming Android based smartphone with high-end performance and with the latest Android firmware pre-loaded by default. However, the price tag is also high, but if you want a phone designed especially for the gaming field, this should be perfect for you. Anyway, for taking full advantage of this new device you should first perform a few tweaks. And in that respect we will start by checking out how to unlock the Razer Phone bootloader.

The bootloader is a small program that runs by default on the Android system. It is there to make everything work: it loads the Android OS along with essential start-up programs and features from the ROM memory into the RAM partition each time your boot or reboot your Razer Phone. So, your phone’s overall functionality depends on this small program. Anyway, the problem is that the bootloader is locked by default.

A locked bootloader means limited possibilities. Built-in restrictions are there to limit your tweaks. So, on an unlocked bootloader you cannot customize, optimize or personalize the Android firmware. Shortly, if you want to bump speeds, upgrade battery life, change the stock Android software and improve general performance you first have to complete this step by step tutorial. And, the best thing is that you can do that easily and quickly without risking too much.

Of course, when removing built-in restrictions we must discuss about certain risks – unlocking the bootloader is an unofficial operation that’s not provided or supported by your OEM. Therefore, if you choose to resume the steps explained during the following lines you are going to lose your Razer Phone warranty. Note: the warranty can be restored if that’s required but only if you decide to reinstall the stock Android software.

Your data might also be in danger – during the unlocking procedure some files might get corrupted or even wiped out. So, the best thing will be to complete a backup on your Razer Phone before doing anything else. A general backup can be ensured by using cloud storage platforms (already installed on your smartphone, or downloaded from Google Play) or by syncing your personal data with your Google Account. As a general recommendation, a good idea will be to save your contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, saved passwords, EFS folder, IMEI / NVRAM data and so on.

You will also have to prepare a few other additional things – unlocking the bootloader is a manual process which can be successfully applied only if the pre-requisites from below are first checked out:

  • A computer, your Razer Phone and its USB cable are required.
  • On your computer you have to install your phone’s drivers first.
  • Also, on the same PC the Android SDK utility must be installed – if you are using Windows, use this guide for learning how to install Android SDK and if you are using MAC OS X / Linux, use this tutorial instead and learn how to set up ADB.
  • On your handset you have to gain Developer Options; this operation can be completed by tapping repeatedly on Built Number (for 7 or 10 times) until the ‘you are a developer’ message shows up.
  • Then, from Developer Options (just go to Menu and then tap on Settings) you should check the USB Debugging field and the OEM Unlocking feature.
  • Charge your Razer Phone before starting the unlocking procedure from below – plug in the charger only if the power left is lower than 50%.
  • Note: if your phone runs low on power its Android OS might get switched off in the middle of the unlocking operation and in that situation you can end up in soft bricking your device – different Android soft related problems might be caused (such as boot loops, lags, bugs, hangs, screen freeze, battery drain, heating problems, battery drain and even total blackouts).
  • Of course, make sure you apply the steps from below only if you own the Razer Phone – everything that’s explained in this tutorial is compatible only with this particular Android based device.

How to Unlock Bootloader on Razer Phone

  1. Power on your computer and your smartphone.
  2. Then, connect your Razer Phone with your computer – just plug-in the USB cord.
  3. On your computer access the Android SDK folder.
  4. From there open a command prompt window: press and hold the Shift keyboard key and while pressing it right-click on any blank space; then select ‘open command prompt window here’.
  5. In this cmd window type ‘adb devices’ and press Enter.
  6. If your device isn’t listed there reinstall its drivers and retry.
  7. Return to cmd and this time execute ‘adb reboot bootloader’.
  8. Now, bootloader mode should be automatically rebooted on your Razer Phone.
  9. Now, enter ‘fastboot –I 0x1532 devices’.
  10. Next, in the same cmd type ‘fastboot –I 0x1532 flashing unlock’ and press Enter.
  11. The bootloader will be now automatically unlocked.
  12. Close the cmd window, remove the USB cable and reboot your Razer Phone.

There you have it; the bootloader of your Razer Phone is now unlocked which means that you can initiate different other custom operations such as installing a custom recovery image (like CWM or TWRP recovery), adding custom MODs and kernels, gain root access, installing a custom ROM firmware (such as Lineage OS, AOKP or Paranoid Android), overclocking or undervolting CPU frequencies, removing bloatware, installing apps from other sources than Google Play and so on.
