Although the Jumper T16 is running JumperTX firmware which is forked from OpenTX, firmware update procedure is completely different. Instead of using OpenTX Companion, you will have to flash your T16 using SD card. In this tutorial I will show you how.
How to Check Latest Version
Even if you have the latest version, check the date of release also. Jumper does release new firmware based on the current firmware version for bug fixes.
Go to Radio Setup page by holding the “SYS” key, then press the “PAGE” button to scroll to the “Version” tab. You want to check if the Version number and release date are the latest.
Here is how to flash new firmware on the Jumper T16.
Download the firmware file here, which is .bin file: https://www.jumper.xyz/jumpertx-t16
If you use R9M module, you can download the FLEX firmware (FLEXR9), if you don’t then it doesn’t matter to you. You can also choose different language here.
To put the firmware file in the SD card, first power the radio into Bootloader mode. You can do so by holding both yaw and roll trim buttons inward while powering on the radio.
Now if you connect the USB cable, it will allow you to access the SD card inside the radio, which will appear as an external drive. Alternatively you can also just take the SD card out and insert it into your computer.
Copy Firmware File in SD Card
Copy and paste the firmware file in the “FIRMWARE” folder. Somehow, I had to rename the firmware file to
T18.104.22.168EN.bin for it to work.
Once it’s done, disconnect the USB cable.
While your T16 is still in bootloader mode, you should see the option “Write Firmware”.
Select it and it will take you to the FIRMWARE folder where you should see the file you just copied there.
Now select and flash the file according to the instruction on the screen. The flashing should only take around 30 seconds to complete. Once it’s done, select EXIT to turn off the radio.
To verify the update, go back to the Version tab and check the version number and release date.
Download SD Card Content
The only time you need to download SD Card Content is when you get a warning on your radio complaining about it, or when you are updating new firmware with different firmware version. Generally, you don’t have to worry about it if the firmware version number is the same (even if the release dates are different).
Here is what to do with SD card content.
First of all, back up your existing SD card content somewhere on your computer. Give it a name such as “T16-date”.
Download SD Card content from the same page where you downloaded the firmware, unzip the file and overwrite the SD card. If you are missing any custom images, sound packs etc, just look it up in the backup and copy them over.
