How to Upgrade Firmware on Leelbox Android Box with USB Burning Tool (2018)

A few months ago, I have written an article showing How to upgrade firmware via SD card. Another method is Firmware upgrade with USB Burning Tool. Most firmware distributed online will probably use the method above, but if you’ve been given a single firmware file, often using the img extension, you need to use another Windows tool called USB Burning Tool. If for some reasons, your firmware is badly damaged, and can’t access the recovery mode, that may be the only way to unbrick your board. Here’s how to proceed. I also attach the video show me how to make it. See below.


1. This method available to Leelbox Q3, (mac number begins with C68) M8S PRO, M8S MAX Android 6.0 tv box; and Android 7.1 Leelbox Q3, M8S PRO (mac: C68…), M8S MAX (mac: C68…), Kingbox K3.  Please ask and check with the customer service before you upgrade firmware. More firmware of other tv boxes please check here.

2. If your Q3 Android tv box is S812, you should know that the Android version is 5.1, this is not supported to upgrade Android 6.0 or Android 7.1, if you don’t follow the suggestion, it will damage the box! Here the upgrade method we wrote is for S912, S905X Q3.

  1. I have tried flashing a firmware update (android 7) on a Leelbox M8S Max (2017) that has 2 G RAM and 16G ROM. I have followed all the steps here (both SD card and USB burning tool). SD Card technique didn’t work at all. The USB Burning Tool starts Flashing but after 2% gives me this error: Romcode/Initialize DDR/Initialize PLL/USB Control setup error. I have also tried with 3 different USB cables. My PC is a Intel 5 CPU (4th gen) and Windows 7 Pro.

    I have tried with 5 different versions of USB Burning Tool (from 2.04 to 2.09) for at least 30 times and all of them give the same errors.

    Please give me a solution. I am tired of trying! Thanks.

    1. Hi, friend
      You should not update with the firmware on your Android 7.1 m8s pro, as I write on this article, it is for android 6.0 m8s max, m8s pro, and Q3, since the 7.1 firmware has not released, so this firmware is not available to your 7.1 tv box. Could you please let me know what’s wrong with your tv box, we will try our best to help you.


  2. I have the new K3, what is the firmware and method to install the operative system again. I installed Xposed Framework because I could´nt install my bank app, but the module to hide Root access ruined my Tv Box, It deleted root, and now K3 does not work properly. Super Su shows every moment, block the system, and does not answer, Apps get stuck …

    I use the tool that they say, after many attempts the PC recognizes me the device, but when it installs the firmware it stays locked at 4% setting this — [0x93610902] Unknown —, I do not know if the access is blocked to install said firmware, that is, if it is to be rotated.
    I ask for your help, attentively Agustin


      1. Send two emails to support @, but they should have a lot of work because I have not received any replies yet, but I tried to open the img file of the rom and all the programs that I tried with did not recognize me file corrupt, can that img file be wrong?

  11. Hello, I already send the emails, I say emails because there have been three, the last since 7 days and there is no way to answer me, I do not know if it is because the K3 has no solution or do not see a solution, I do not know if you have an opportunity to address them, but if you have to help me, there is no way to load the firmware
