How to flash CPB firmware using QGDP Tool

QGDP Tool is a small application for Windows Computer, allowing you to Flash the CPB Firmware on Android smartphones and tablets.

Here on this page, we have managed to share the official and tested version of the QGDP Flash Tool, i.e., QGDP Tool SMT v3.2.6.

QGDP Tool is the successor of YGDP Tool, which allows you to Flash or install the .cpb Firmware on Android smartphones and Tablets.

Here on this page, we have shared the latest version of the QGDP Tool and the previous versions.


Features of QGDP Tool


QGDP comes as an installer application, which means you have to install it on your computer to use it. In contrast, the QGDP Assembly V3.2.0 comes as a portable application, which doesn’t require you to install it.

Simple Interface:

The overall interface of the QGDP is the same as YGDP Tool, which also allows you to flash or install the Firmware. However, in QGDP, you will be getting more functions and support to the CPB Stock firmware.

Multiple Versions:

QGDP comes in three variants, i.e., QGDP Assembly, QGDP Customer, and QGDP SMT. Few of the CPB Firmware might not be compatible with the QGDP Assembly; then, in that situation, you can try the QGDP Customer or QGDP SMT version.

Support latest CBP Firmware:

YGDP Tool supports much older and latest CPB Firmware, but sometimes it fails to support the latest CPB firmware. In that situation, you will need the QGDP utility, as it supports the latest CPB firmware.


Using the Configuration panel, you can load the CPB firmware on the QGDP Utility. Besides loading the Firmware, it also allows you to check the device name, test the eMMC CID, Test the Fuse information, and Test the instrument information.

Massive Cell Support:

Using the QGDP, you can simultaneously flash the stock firmware on up to 15 devices. On the YGDP Tool, you could only flash the Firmware on up to seven devices at a time.
