How To Update The Firmware Of Cubot Smartphones Guide

Cubot Smartphones Guide

In this step-by-step guide, I explain how to update the firmware of Cubot smartphones. The Android firmware update allows you to update the operating system to the latest version, improving performance, functionality, and security.

If you have a Cubot mobile phone, you will surely have noticed that the Chinese manufacturer does not release firmware updates via OTA. For some strange reason, Cubot smartphones have to be updated in the old way: via PC.

Having your smartphone updated to the latest available firmware version allows you to have the most updated version of the operating system, better performance, and updated security patches. Performing the Cubot firmware update is quite simple but the steps to follow are several and must be followed in precise order.


  • This guide is valid for all Cubot smartphone models produced from 2018 onwards and also applies to the latest models such as Cubot X20 Pro.
  • The firmware update deletes any data present on the smartphone. Make sure to backup all your data before proceeding.
  • Download tools and ROMs only from reputable sites.
  • If during the procedure you encounter any problems or the flash does not start or fails, perform all the steps again.

Software and ROM downloads

The first step is the find firmware for the Cubot from this site and downloads these two files:

If you use a PC with Windows 7 or Windows 8 you must also download the drivers and install them. If you use a PC with Windows 10 you don’t need to download any drivers. If you use Mac or Linux, unfortunately, there are no compatible tools.

Once the download of the files is completed, and the possible installation of the drivers, extract the files from the ZIP archives keeping them in two separate folders.
