How to Unlock Bootloader on Cubot Devices

In this guide, we will show you the detailed steps to unlock the bootloader on any Cubot device. The budget device segment is already filled with a plethora of offerings. However, in spite of that, this Chinese OEM has managed to carve out a name for itself. Boasting of all the required feature sets but at a price tag that wouldn’t burn a hole in your pockets, these devices manage to checkmark most of the prerequisites.

Along the same lines, they are slowly but surely catching in the custom development as well. Be it for flashing custom ROMs or trying a custom recovery, there’s a lot to look forward to. Along the same lines, you could also gain administrative privileges by rooting your device via Magisk. But before you could try out any of these tweaks, you would need to have to unlock the bootloader on your Cubot device. And in this guide, we will help you with just that. So without any further ado, let’s get started.

Benefits and Risks of Unlocked Bootloader on Cubot Devices

Unlocking the bootloader is the gateway to extract maximum benefits of Android’s open-source ecosystem. For example, you will be able to install a custom ROM or flash a custom recovery like TWRP. Likewise, you will also be able to get access to the system partition as well as administrative privileges by rooting your device via Magisk. This will then allow you to flash Magisk Modules, Xposed Framework, Substratum Themes, Viper4Android, Custom Kernels, among others.

The SafetyNet will be triggered as well, thereby preventing you from using banking apps [FIXED]. So if that’s well and good then let’s get started with the steps to unlock the bootloader on your Cubot device.
