Firmware Update Guide for Smartphone or Tablet with Mediatek SoC

Today we present a guide to update, restore, recover or make an unbrick of any device with Mediatek SoC. In this guide we explain how to install the necessary drivers, where to download the firmware for our tablets or Smartphones and how to perform the update process from a PC.

• NOTE: AndroidPCtv is not responsible for problems that may cause a firmware change. If your device works well, do not change.

BASIC CONCEPTS AND CONSIDERATIONS

As it is always recommendable to use OTA updates before trying to flash a device that works with a firmware from a PC, we advise using this guide as a resource to recover our tablet if there is no other option.

!ATTENTION !

• If the TV Box works well for our needs DO NOT UPDATE
• If we don’t know what we are doing DO NOT UPDATE
• If our TV-Box don’t work and does’t have reset button DO NOT TRY TO UPDATE , claim to the store.
• If you do not find firmware for your model you may not have any brand support.

FIND MEDIATEK FIRMWARE 

There is an almost infinite number of Mediatek devices, but basically the most popular are their smartphones and tablets, depending on the brand of the device we will have different options to download the firmware, we recommend looking for them in this order.

1. From the website of the manufacturer of our device either a whole firmware or a partial update as OTA, some examples:
   – Chuwi’s website, there is a lot of info in their forums too
   – Teclast website, requires the number on the back of our device (only in Chinese)
   – Web of Cube or Alldocube, you have to search by reference (only in Chinese)
2. Search firmwares in Google, you have to be careful with and download files from serious sites, looking in XDA is a good option, there are many tutorials and users commenting in case there is any problem.

INSTALL DRIVERS MEDIATEK IN OUR PC

Before starting to update our Mediatek device, we need to install the necessary drivers for our computer to detect it and be able to communicate with it, for this we will need to follow a few steps.

1. Descargar el programa instalador de drivers Mediatek, descomprimirlo y no ejecutar.
2. We must disable the driver secure enforcement in WINDOWS 10:
   Before running the installer of the flashing program we need to disable the secure signature of drivers.
   – Windows 10: Start Menu> Settings> Update and Security> Recovery>
   Under the Advanced Start option, click Restart Now> Troubleshooting> Advanced Options> Startup Settings> Restart> Press 7 or F7 to Disable the mandatory use of signed drivers.
   
3. The system will boot and we can install the drivers without a signature.
4. We go to the folder where we have the driver installer and with the right button to execute the app as administrator:
   DPInst64.exe > for 64bit systems
   DPInst64.exe > for 32bit systems
   Normally our PC will be 64bit but we can check it in Settings> System> About> Type
5. The program will run and press next, we will skip a warning message and click on Install anyway.
   
6. At the end we have an a affirmative message of installation of drivers and we can restart.
