Hello fellows, I'm back now.
I'm re-posting the instruction for burning firmware with USB cable.
Let's cut the cackle, go straight to the point.
------------------------------------------------------------
Caution
Please note that firmware burning will clean all data in the device, make sure to back up the important data before doing it.
Preparation
A homemade usb cable
Follow the figure below to make a customized usb cable for firmware burning.
1. Prepare two common USB data cables.
2. Cut and divide evenly each of cables into two parts, keep the half parts of Type-A plug, throw away the half parts of Micro-B plug.
3. Directly connect two half parts of Type-A plugs: joint the wire cores of the same color together.
A Desktop Computer
Prepare a PC for firmware burning, better choose a desktop computer than a laptop, in general the rear usb ports in the desktop computer have more stable capability of power supply.
Tool
File Name: USB_Burning_Tool_v2.0.8_x86.7z
Use 7z or latest WinRAR to decompress the file package, and install it into the windows system.
Firmware for Demonstration
Build Number (Firmware version): FWforDemo.H3.S912.20180710.release-keys (Build Number is located in Settings->About>Build)
Firmware Package Name: FWforDemo.H3.S912.20180710.release-keys.7z
SHA1: 07A5DC6E69896C9881B9EFD4D1642FC5EF329BA3
Download Link: Ask the official customer service for it.
Use 7z or latest WinRAR to decompress the firmware package, and remember the location of decompressed files.
Attention: The firmware used for the demonstration is not guaranteed to be compatible with your device, so you're supposed to ask the official customer service for the correct and latest one.
Burning Process
1. Double click the shortcut to run USB_Burning_Tool.
2. If the UI doesn't show in English, follow the figure to change it into English.
3. Click File -> Import image -> Select the .img file -> Click Open, import the firmware image file to the tool.
4. Wait till the image checking done.
5. Make sure the configuration is exactly same as the figure below, then click start button.
6. Press and hold down POWER key and do not loosen it -> Use the homemade usb cable to connect between desktop computer and TV Box: One end of cable plugs into one of the REAR (More stable power supply than front) usb ports in desktop computer, and the other end plugs into the OUTSIDE (not the inner side) usb port in TV Box -> When the status is changing on the user interface of the burning tool, loosen the POWER key, and wait.
7. Wait about 2 minutes, When “Burning successfully” comes out on the status progress bar, unplug the usb cable from TV Box, press down the POWER key to check if TV Box can boot up.
Attention: If this current usb port of the desktop computer has never been used for firmware burning, the first time burning that you try is likely to fail due to the windows system needing to load the usb port driver. If it fails, please try again.
Notice
After burning done, the first boot of system will take more time than normal boot, and after the first boot is done, the system still needs to reboot automatically for 2 times, to initialize resources for APP service, it will take approximate 5 minutes. It is very necessary, please wait patiently.
