Hi guys here is a we guide on how to successfully de-brand you 3 device in order to get OTA updates working and installing correctly.


1. You will need adb and fastboot installed on your system in order to do the process.

For windows systems you can refer to this thread on installing adb and fastboot
https://forum.xda-developers.com/showthread.php?t=2588979

For linux based systems you can install both using this command

For Debain Based i.e Ubuntu, LinuxMint etc...
Code:
sudo apt update
sudo apt install android-tools-adb android-tools-fastboot
For Centos or Fedora you can use this command:
Code:
sudo yum install android-tools
2. Download the required Global Razer factory image
cheryl-global-851.zip

3. Unlocking the bootloader

WARNING: THIS PART FORMATS YOUR USER DATA SO MAKE A BACKUP OF YOUR INTERNAL STORAGE BEFORE PROCEEDING.

After you have everything installed and the image downloaded you will need to unlock two parts of the bootloader snippets from Razers site:

Unlocking the Bootloader

Enable OEM Unlocking

  • If necessary, enable OEM unlocking on the Razer Phone:
  • On Android 7.x, go to Settings > About phone > tap Build number seven (7) times.
  • Tap the back button once you see the “You are now a developer” message appear.
  • Tap Developer options, tap toggle OEM unlocking to enable.

Enter Download Mode

  • Start the Phone in Download Mode with one of the following methods:
  • Using the adb tool: With the Phone powered on, execute: adb reboot bootloader
  • Enter Download Mode: Plug in a USB cable to connect your Razer Phone to your computer, Power Off the Phone, then turn it on and immediately press and hold the Volume Down button until “Download Mode” appears on screen.

Unlock the Bootloader

  • Run this command: fastboot flashing unlock
  • Your Razer Phone will show you a confirmation screen. Use the Volume Up/Volume Down buttons for navigation, and press the Power button to select. Your Phone will reboot.

Unlock the Bootloader Critical Partitions

  • Enter Download Mode: Plug in a USB cable to connect your Razer Phone to your computer, Power Off the Phone, then turn it on and immediately press and hold the Volume Down button until “Download Mode” appears on screen.
  • The unlock can be performed with this command: fastboot flashing unlock_critical
  • Your Razer Phone will show you a confirmation screen. Use the Volume Up/Volume Down buttons for navigation, and press the Power button to select. Your Phone will reboot.

4. Flashing the image.

  • Download the appropriate system image for the Razer Phone from here, then unzip it to a safe directory.
  • Connect your Razer Phone to your computer over USB.
  • Start the Phone in Download Mode with one of the following methods:
  • Using the adb tool: With the Phone powered on, execute: adb reboot bootloader
  • Enter Download Mode: Plug in a USB cable to connect your Razer Phone to your computer, Power Off the Phone, then turn it on and immediately press and hold the Volume Down button until “Download Mode” appears on screen.
  • If necessary, unlock the Phone’s bootloader. See Unlocking the Bootloader and Unlocking the Bootloader Critical Partitions for instructions.
  • Open a terminal on your computer and navigate to the unzipped system image directory.
  • Execute the flash_all.sh script if on linux or on windows run flash_all.bat. This script installs the necessary bootloader, baseband firmware(s), and operating system for your Razer Phone.
  • Once the script finishes, your Phone will reboot.

5. Covering up what you have done i.e removing the error during boot.

Locking the Bootloader

  • Locking the bootloader is recommended for security reasons. Some applications will not work with an unlocked bootloader.
  • Start the Phone in Download Mode with one of the following methods:
  • Using the adb tool: With the Phone powered on, execute: adb reboot bootloader Enter Download Mode:
  • Plug in a USB cable to connect your Razer Phone to your computer, Power Off the Phone, then turn it on and immediately press and hold the Volume Down button until “Download Mode” appears on screen.
  • Lock the critical partitions of the Bootloader first by running this command: fastboot flashing lock_critical
  • Your Razer Phone will show you a confirmation screen. Use the Volume Up/Volume Down buttons for navigation, and press the Power button to select. Your Phone will reboot.

  • Enter Download Mode: Plug in a USB cable to connect your Razer Phone to your computer, Power Off the Phone, then turn it on and immediately press and hold the Volume Down button until “Download Mode” appears on screen.
  • Locking the remainder of the bootloader can be performed with this command: fastboot flashing lock
  • Your Razer Phone will show you a confirmation screen. Use the Volume Up/Volume Down buttons for navigation, and press the Power button to select. Your Phone will reboot.

Once you have done all that your phone will be de-branded

thanks to @Xplicit1992 for tipping me off that otas work after flashing the MR1 global image

I bought the phone on contract with 3. If I do this will it break VoLTE ("4G Super Voice")?
Honestly don't know how to test volte that.

For best results I recommend using a Ubuntu live disk when flashing the images or make a small dual boot on your PC dedicated to flashing your phone.

Thankyou very much for the guide it worked a treat.
I had to slightly amend your script as I was also having the fasbtoot only recognising "fastboot -i 0x1532"

But only had to change one part of your it so the rest of the script would use "fasbtoot" as fastboot -i 0x1532

Worked as it should.

But thanks again. Anyone else having similar issues I can confirm this worked with my 3 branded device.

While your phone is in download mode check the device manager on the PC see if it detects the device properly or has a warning triangle beside it. If it does then your PC isn't detecting the hardware properly and you'll need to download android ADB drivers.

yep that's your issue then. right click on it and select "update drivers" then select the option that reads something like install from your computer then to chose a driver. if you can't see "Android ADB" then you'll need to install these https://developer.android.com/studio/run/win-usb.html then do what I said there.

Should get your computer talking to the phone in download mode
