How to install the new Ugoos firmware
Ugoos has all of their firmwares listed on their website’s Download Center. Everything is in date order so its pretty easy to find out what the latest file is. The files are hosted on Mega, but you don’t have to create an account in order to download them.
Once the file is downloaded, unzip it to a temporary directory. You’re going to have two subfolders – BatchTool and DriverAssistant -, and the image file. You’re also going to have a word document manual, but there’s a better pdf instruction file in the download area or attached here: ugoos_firmware_upgrade_guide
Install the Ugoos PC Drivers
If you haven’t installed the PC drivers for your UT3 before, you’ll need to do that before you can upgrade the firmware. In the DriverAssistant folder run the DriverInstall folder as highlighted in the picture below. If you’ve installed any drivers manually on your PC, this is pretty much the same process, so I won’t go into it in detail here. The actual driver will be in the Driver subfolder.
Once that’s done, you can go back to the BatchTool folder and run the RKBatchTool.exe file. This is the program that will actually extract the firmware to the UT3 from your PC.
Update the Firmware
Once your drivers are installed and the BatchTool is up and running, it’s time to connect it to your PC. Take the blue USB cable, plus it into the OTG port on the UT3 and an available USB port on your PC. The port will be labeled, and you’ll find on the same side as the Recover button and HDMI in port.
Once the USB cable is connected, hold down the Recover button and turn the UT3 on using the main power button. This will cause that green “Connected Devices” icon to light up as you can see on the screen here.
Click on the button in the upper right hand corner to select your firmware image. This will be in the same directory as the BatchTool and the Driver Assistant. I like to double check my language option before I hit the Upgrade button.
From here the process will take over and run for a little over a minute. You’ll hear the normal Windows sounds for devices connecting and disconnecting a couple of times. Don’t worry, that’s normal.
You’ll also see the individual tasks that are being done and the status there right underneath the flashing yellow box. Newer versions of the firmware are available over-the-air, so you have that option. Here we upgraded from an older version, so that wasn’t an option.
Once you’re done, you’ll get an “Upgrade Done Successfully” message . After that, you can disconnect from your PC. Congratulations! You’re done!
Initial thoughts on the new Ugoos firmware
I’d like to say that this was a quick and easy process, but I really can’t. Like I said earlier, there’s a new document on Ugoos’s Download Center which goes into a bit more detail for the UT3 and UM3, but the document included in the firmware leaves a bit to be desired. So that’s why I created the video tutorial shown above and on our YouTube channel.
The hardest part for me was trying to get the drivers installed. It required a bit of a balancing act with one hand pressing the recover button, one controlling the mouse while balancing the UT3 on my knee with the short cable.
Once I figured out the right way to connect the UT3, the rest of the process was much, MUCH easier.
I always recommend installing the latest firmware, unless you’re running some application that absolutely needs an older version. There’s tons of small improvements, bug fixes and security updates which make it worthwhile.
