Sep 30, 2014. Tool for USB Transmitter 6 Channel 2.4GHz for HobbyKing, FlySky. In a drop down control as it happen in the original t6config software.
Here is how you can update firmware on Flysky Nirvana radio transmitter to the latest firmware developed by UndergroundFPV. Note: this guide is only for Nirvana radios of the UndergroundFPV version.
The Flysky version uses a different firmware and the update method might be different. I only own the UndergroundFPV version, so I am not sure how the Flysky one works. Check Version If you’ve previously updated the firmware on your TX, firmware updating is going to be easier for you.
To check, simply go to Radio Setup (Home page, middle icon on the top of the screen) Scroll to the last menu, Version. If you see the option “Firmware update” as shown below, then it means your radio has a newer firmware. If you don’t have the Firmware update option, it means your radio is still on the original firmware it ships with from factory. To update the firmware you will first have to put the radio into “DFU Mode” for your first update. Enter DFU Mode If you have the “Firmware update” option in the Version page, you can ignore DFU mode.
Only radios with old firmware that don’t have the option need to do this. Remove the screws for the neck strap holder, and you should see two screw holes. The top hole has a hidden push button you can press with a toothpick. Press the button when you plug the USB cable in, this will put the radio in DFU mode.
In DFU mode you will use the updater as normal instead of clicking the “update firmware” option. Make sure to remove the batteries first. Download Nirvana Firmware Updater In the Version page under Radio Setup, you can find the UID number, a 16-digit number.
Go to and enter it there: When verified successfully, you will get the following screen. If it fails, contact UndergroundFPV (either email or Facebook group), send them your UID and they will add it to the database. On this screen, you can download the firmware updater and driver for your Nirvana. The updater is available for 32bit/64-bit windows, Linux and MacOS. Update Nirvana Firmware Unzip the file you downloaded, and find “NV14-updaterwithdriver.exe”. The program will say “Detecting TX”, but it won’t do anything until you hit “Firmware update” option on the Nirvana (Radio Setup = Version). Like we mentioned, there is no “firmware update” option in the old firmware, so you’d have to put the radio in DFU mode for this to update.
Once you’ve done that, the program will start loading. Once it’s finished loading, you would be able to select a firmware on the left hand drop-down list.
There is a firmware designed for Crossfire module too. Once selected the firmware, click “Download firmware” on the top of the program. Once the download is finished, click “Update TX” on top of the program. The update will begin and you will see the following screen: It’s going to take a few minutes. Once it’s done your will be prompted to “restart the radio”. And that’s it, the radio is updated.
