Tutorial: How to Flash OpenTX Firmware to Radio Transmitter

by Oscar
Published: Last Updated on

This tutorial explains how to flash OpenTX firmware to your radio. To stay up-to-date with the latest version for bug fixes and new features, it’s recommended to keep OpenTX software updated on your transmitter regularly.

The same procedure should work on most if not all the OpenTX compatible radios, including Frsky Taranis X9D, X9 Lite, QX7, X-Lite, Horus X10/X12, Jumper T12/T16/T18 and Radiomaster TX16S.

You don’t have to update OpenTX if you don’t want to. But do check firmware release note and see if there is any particular bug fixes or new features that might interest you.

Download OpenTX Companion

OpenTX Companion is the software we will be using to flash OpenTX to our radio, and to manage settings and models.

Download OpenTX companion here: http://www.open-tx.org/downloads

I am not sure what the best practice is, but I always download and install the latest version whenever I want to update OpenTX on my radios just in case.

Find the version you want (preferably the latest one).

Scroll down to the Download Links section to download and install “OpenTX Companion” to your operating system (Windows, Mac or Linux).

Make Backup First

After flashing OpenTX firmware, your model profiles should still be there, that includes their settings. You shouldn’t need to to re-bind receivers, everything should work as they were before. With that said, you should still make backup of the models, existing firmware and SD card content before flashing OpenTX, just in case something goes wrong.

To do that, first put your radio in Bootloader Mode.

For Jumper T16, T18 and Radiomaster TX16S, you need to press both horizontal trim buttons inwards while powering on the TX:

For the Frsky Taranis X9D it’s the same:

For the Taranis Q X7:

For the Frsky X-Lite, you need to hold down the trim button at the center (make sure all 4 trim buttons are pressed), then power on the TX.

 This is how bootloader mode screen looks like:

Once the radio is in bootloader mode, you can plug in a USB cable to the radio and connect it to your computer. The screen will inform you about the USB connection.

Start OpenTX Companion you just installed on your computer.

There are 3 things to backup:

  • Models
  • EEPROM
  • Existing OpenTX firmware

To backup Models, find the icon on the left hand sidebar, that says “Read Models and Settings from the radio“. It will display your models in a new window. You can then save it as a “.otx” file on your computer. (Click on File => Save as)

To make a backup of EEPROM , find the icon on the left sidebar that says “Backup Radio to file“. It will create a “.bin” file that you can save somewhere on your computer.

Finally, to back up the existing firmware, find the icon that says “Read Firmware from Radio” in the same sidebar, and save the “.bin” file.

Alternative Way of Backing Up EEPROM and Firmware

Not officially recommended, but you could also try this if you have trouble using Companion.

When connecting the radio to computer in Bootloader mode, it will mount a new external drive and there are two files inside the drive: FIRMWARE.bin and EEPROM.bin, these are the two files we want to make a backup of.

To backup EEPROM, you can also go to Radio Settings, scroll to Hardware (V2.3) or Version (V2.2 or older), long press the Enter button, it will create a backup file of EEPROM in the EEPROM folder on your SD Card.

Compile OpenTX Firmware

We have to “compile” the firmware first by selecting the features we want to have, then we can save the firmware file and write it to the radio.

Click on the SETTINGS button on the top row (the gear icon).

Edit Settings, Radio Profile

In the Edit Settings / Radio Profile tab you need to choose the radio type you are about to flash from the list.

Select your radio from the “Radio Type” drop-down list.

Select the following build options:

  • lua / luac– to be able to use LUA scripts (must have)
  • noheli – to exclude helicopter config as I only fly quadcopters and wings

Optional:

  • If you want to use the EU version of OpenTX, select eu. For International version, just leave it unchecked
  • sqt5font – slightly better font on Taranis X9D screen (looks good on telemetry screen)
  • flexr9m – if you use Frsky R9M module with Flex firmware, you have to select this option
  • internalmulti – select this if you have internal mutiprotocol module (for Jumper T12 / T16 / T18 and Radiomaster TX16S)

SD Structure Path: You have backed up your SD card in the radio already right? Then just select the copy of your SD card here. This allows OpenTX companion to populate the model image selector with the images that are on the card, and do the same for audio files.

Stick Mode and Default Channel Order: I recommend using Mode 2 and AETR because this is the default in Betaflight. See this post if you don’t understand what channel map is.

For Taranis users, you can also upload your custom splash screen image on this screen. This is the logo that appears at power up, and it can only be uploaded when you flash OpenTX firmware. The required image format and size for the QX7 is monochrome BMP 128×64 pixels. For the X9D it should be 212×64 pixels.

Edit Settings, Application Settings

In Application Settings tab, you don’t really have to change anything normally.

The only setting you should know about is “Release Channel“. If you wish to flash a release candidate (RC) or unstable nightly build, you enable it there. However, I recommend flashing only stable releases, if you decide to flash unstable releases, do so at your own risk.

Download OpenTX Firmware

Press OK to close the “Edit Settings” Window, and press the Download icon from the toolbar:

In the Downloads pop up window, press “Check for updates” and you should be prompted to save the firmware file (with .bin file extension). If not, Press Download Firmware to download it.

Update SD Card Contents

Press Download SD contents will take you to a website, where you can download the SD card content you need to copy to the SD card inside your radio.

You want to get the one with the same release date as the firmware you just release. If you just flashed the latest firmware, then get the latest SD Card Contents.

Back up the SD card files on your computer first, then delete everything on it, and copy the new SD Card Content to it. Then copy any custom files you had previously, I usually just overwrite those folders from the backup like

  • IMAGES
  • SOUNDS
  • MODELS

It is important to delete the old content on the SD Card before copying the new files there. Otherwise you might get a warning message on the startup screen, complaining about “the SD card content being incompatible with current OpenTX version”.

Flash OpenTX Firmware to Radio

Once you’ve complied and downloaded the firmware file, click Write Firmware To Radio button on the left side menu. Load the firmware file you saved previously, and click “Write to TX”.

Once the flashing is done, you can unplug USB cable. That’s it, you have successfully updated OpenTX on your radio.

Restoring Backup

For whatever reason you want to roll back to previous state, you can always restore the radio firmware, EEPROM and models that you backed up before flashing.

Simply use the buttons on the left hand side menu in OpenTX Companion to write those backup to the radio:

  • For models: “Write Models and Settings to Radio”
  • For EEPROM: “Write Backup to Radio”
  • For firmware: “Write Firmware to Radio”

For EEPROM you can also do this:

  • copy the backup file to the SD card
  • enter to bootloader mode and choose Restore EEPROM

Flash OpenTX in DFU Mode

If for some reason you can’t turn on the radio, you can still flash it under DFU mode.

Connect the radio to computer via USB cable, your computer should detect a new device connected. Then run the ImpulseRC Driver Fixer (download) if you haven’t done it before just in case, it installs/fixes the DFU driver on your computer. Make sure you don’t have other DFU devices (such as flight controllers) connected so your computer doesn’t get confused.

Now go to the Companion menu, “Read/Write”, and select “Write Firmware to Radio”.

In the pop up window, select the firmware file, and click “flash”.

The flashing screen is a bit different than what we described previously, but the result is the same. You will get a warning saying “File has no DFU suffix”. It’s normally just ignore it.

By the way, flashing via DFU mode also updates the radio’s bootloader firmware. So if you also want to update the bootloader you can flash OpenTX this way :)

Updating OpenTX Bootloader

Your radio might work without ever updating the bootloader, and you probably won’t notice any difference. But for some radios with really old bootloader, it might cause issues in new version of OpenTX and you might have to update it, for example you could run into errors when flashing your receivers from the radio.

To update Bootloader, just flash your radio’s OpenTX firmware via DFU mode as described above. Alternatively, this is how to update OpenTX Bootloader manually.

Hi Oscar I have a problem. I up dated open tx your way but now there is no boot loader screen. I push both trims to the center and turn it on and it goes to the splash screen. Any ideas? Thanks if you can help.

Thanks so much for this. I struggled with other YT vids and other websites with updating my XD9+. Couldn’t use very old one with VelociDrone ( or a Win10 issue because of drivers, still major issues with BetaFlight :(

You saved me a lot of time, time I don’t have since have to do pool therapy everyday and most days can’t even touch the laptop to get back to flying drones again (lockdowns physically set me back over a year with 2nd one).

Thanks for your time.

If that happens after flashing firmware, try a different version and report issue to the developer?

Hello, OpenTX 2.3.9 doesn’t show a crsf option for lua scripts, and doesn’t show up in my radio, is there an option I’m missing to select it? Should I downgrade? The layout in Companion is different from your reference. Thank you for putting this together.

Good article but won’t work when flashing X9D+2019 SE to OpenTX version 2.3.0 with shown features enabled.

The following needs to be included:
+ noheli
+ flexr9m
+ lua
(ps: no loac option available)

I just upgraded from opentx 2.0.15 to opentx 2.3.5 . Model data was partially there but corrupted.
I attempted to roll back to the firmware that I backed up using Companion 2.3 to try again at backing up my models.. however after doing so my taranis appeared dead, I was quite concerned. Fortunately I read on the web somewhere to take out the battery and try again, it came back to life.

So I tried the method to restore the firmware as mentioned on this page.
Putting the firmware in the eeprom folder and selecting restore eeprom from the Taranis menu, that did not work, Taranis rejected it saying it was not an eeprom file. (are you sure the info on this page is correct, as I understand it eeprom is different from the fireware? I think the eeprom just saves current firmware settings, there is a different folder for firmware)

However I tried to restore old firmware with Companion 2.3 again and it worked this time, also I had to restore the models backed up at same time as the firmware.

This time I read models from Radio to Companion 2.3 and checked them over before attempting to save in a otx file. They were corrupt..

To rescue my models, downloaded all versions of Companion, 2.0, 2.1, 2.2, 2.3, and attempted to see if any of them could load the models correctly from a backup I had made from within the Radio to the sd card, (but I assume the same process would work for Reading in the Models from Radio with usb) .
I loaded them in 2.0 worked but didn’t help the situation.
2.1 loaded the files and needed to convert them and did so correctly but also wouldn’t save to otx format, only to a .bin , so I saved the models in that format. Then loaded those in Companion 2.3 which correctly converted the model files finally, and allowed me to save in .otx format.

Hi Oscar,
Thanks for making this tutorial.
There are a few that I want to ask.
I have an Taranis X9D taranis with opentx-taranis-plus firmware version 2.1.8.
I tried updating the firmware to version 2.2.4 but it always failed.
always exits the command “New firmware is not compatible with the one currently installed”.
What should I do to be able to update the firmware.
Many thanks for your answer

Hi Oscar,
you mention in the “Update Taranis Bootloader” section that you can flash OpenTX via the SD card. I just had a discussion if that’s possible and I wasn’t aware of that. I found little resources on that topic on well written guides. So maybe it’s a good idea to add that to the tutorial? Just in case someone breaks the USB port or has issues with the drivers.

I flash Taranis with OpenTX 2.2.2 and I can not use with with simulator. It is recognize as memory stick.
In companion even is no option for massstorage.
How to fix it?

In the model setup page, scroll down and you should see “USB connection”, you probably have SD drive selected, choose “Joystick” instead :)

Hey Oscar, I’m getting confused. When I watch Joshua Bardwell video on how to upgrade the xlite, which he said would be the same as for my x9d+. He flashes the firmware to the controller, after using impulse rc driver fixer. Thats where I am confused. I can connect my controller to my pc, and open TX, its on 2.2.0 I downloaded the firmware, I got the SD contents. How come he is not using bootloader mode? Thanks

A question rather than a reply. I have upgraded my X9D to OpenTX 2.2.2 successfully suing your instructions The radio works just as i expected but when switching the Tx on first thing I get an error message that I have the wrong SD card. I actually updated the SD card to the suggested version and all sound files work as well as Lua script for the SxR RX. So how can I remove this error message please.

Oscar 28th August 2018 - 5:09 pm

did you try format the SD card before copying the files in there? Make sure the SD card content is the same version as the firmware.

ERROR FLASH OPENTX – TURNIGY 9XR PRO 2018

The TURNIGY 9XR PRO 2018 Flash with OpenTX, but I’m having a problem.
The problem occurs for the new tested versions of OpenTX: “2.0.20, 2.1.9, 2.2.1”.
SD card flash it displays a message: “EEPROM warning – wrong EEPROM data – Press any key”.
After the EEPROM is installed, the EEPROM Recording process will appear, by means of a blinking screen after a while. in this context, without starting OpenTX.

I cannot get my Taranis X9D+ to connect to The Drone Racing League simulator. It just says “no Hardware” on simulator. The simulator will recognize the Realflight Interlink. I do not have a “massstorage” option on my Companion to check or not to check. I tried checking the box that says “enable” on the Simulator settings tab but that just says “no joystick found” when I know it is connected, it allowed me to flash the firmware. AARRG so frustrated spent more time than I’m wiling to admit on this and it should be so simple… I have installed countless drivers and updates and fixers, even the one recommended on the DRL sim website. My computer reads the controller as a Bootloader when plugged in not in Bootloader mode and shows as a USB mass storage device when plugged in in Bootloader mode. Any suggestions would be so much appreciated!!! ~X(

Thanks for this easy way to update the firmware on a TaranisX7. I have a question—how do you replace the contents on the tx sd card with the new contents? You mentioned it at the end of the tutorial, but did not explain how to do it. I assume that you mean the sd card inside the TX. Thanks!!

Reply

Yes, the SD card in the Taranis. Copy everything on the SD card to somewhere on your computer (backing up), then delete everything on the SD card, and copy the new content in there.

Hi tried upgrading from 2.1.7 to 2.2.1, on my Taranis plus with TX off, Companion said all OK but now all I get is a loud buzzing and a bright blank screen. It shows up as STM32 BOOTLOADER so I know drivers are correct and have tried on both Win 10 and 7 machines.
On settings screen I chose correct TX (XD9plus) but I did uncheck the check hardware box as suggested on other forums.

I then followed advice from opentx (open-txu.org/home/special-interests/curing-a-bricked-taranis/), no luck.
Companion again said OK, this time I checked the check hardware box.
Although I can now read the sd card but nothing else. So somethings working.

I think I killed it. Can no longer enter bootloader mode or any mode at all.

Is there any way to recover ? Any ideas?

One final question has anybody used DfuSeDemo to unbrick?
Thanks

Reply
Larry Krause 18th January 2018 - 5:07 am

Update
Problem solved. Wasn’t easy or quick.
Found on net a Dfu file for version 2.1.6 and using DfuSe was able then load this to Taranis inDfu mode.
Then through Companion could load 2.1.9 all good.
Then tried again to update to 2.2.1 same problem.
Went back to and repeated using DfuSe and Companion to load 2.1.9.
Now will stick with 2.1.9 if it ain’t broke dont fix it!
Apparently the shake of death and blue screen happens often but usually only when trying to load incorrect firmware for TX.

Great instructions Oscar. have just upgraded a Taranis QX7 to OpenTx2.2.1 for a friend including new SD structure. I was hoping that the Model configurations on my X9D+ would transfer to the Tararnis QX7 but it says these are incompatible when I try to restore copied files from the X9D to the Model folder on the QX7. Am I doing anything wrong?

I’ve been able to upgrade Taranis firmware by pulling the SD card out and flashing it from a laptop’s SD card reader. This has been verified by checking PG-4 screen to see that the firmware has indeed installed. Everything works and I can fly using my profiles as per usual. However not once been able to connect to a computer via the USB cable. I can get into boot-loader ok and the Taranis sees the cable is connected but the OpenTX software will not connect to the device. Both my Laptop and PC have the same issue connecting to the Taranis.

Previously when connecting Betaflight to a multirotor I had similar issues but that’s since been resolved. Yet the Taranis USB gripe still remains an issue despite everything else working correctly. Anyone have an idea what’s going on here and why OpenTX?

Note: Same cable used to connect to multirotor and perform serial pass through is being used so I know its good. Tried zadig-2.3 with the same results on both systems.

Thanks in advance!

Oscar,
Thanks for the excellent Blog and all the detailed R/C posts.

My FrSky Taranis X9D (Rev.B) is still on v2.0.12. I would like to get my Taranis up to v2.2.0 with as little trouble as possible.

1. Should I upgrade from 2.0.12 to 2.1.9 first, and then go to v2.2.0 ? Or, can I go straight to v2.2.0 without causing any problems ?

2. I will backup my Taranis config and Models first, but should I expect to lose/change any programming during the upgrade?

You can just flash it to directly 2.2.
Models should still be there after the update, but back it up anyway just in case.

I appreciate the time in creating this tutorial to help those of us that are just getting started. It took me a while to figure out how to “replace the SD Card content”. Might be good to include the steps for that.

Thanks again.

Reply
Allan 19th July 2017 - 1:58 am

It took me a while to figure this out too. To overwrite the SD Content:

1. Go to open-tx.org.
2. Scroll down to News, click on the version of OpenTX you just downloaded.
3. Scroll down to Download links, then click on the link for “SDCard content for x.x.x” You will go to a folder listing.
4. In the list, select your Taranis model.
5. Download sdcard-taranis–.zip.
6. Extract the zip file to a folder.
7. Connect to your SD card. This can be either through the USB on the radio (if it shows up) or directly in some SD card reader.
8. It’s a good idea to copy the contents of the SD card as a backup.
9. Copy the contents of the zip file you downloaded and overwrite the contents on the root of the SD card of your radio.

Please change your instructions not to select the massstorage option, or explain that it will disable joystick. People do it simply becasue you say so without knowing why, and as a result there’s about a dozen people per week asking why their jhoystick doesn’t work anymore.
There is no reason to use this option in normal setups.

I think it is worth mentioning that if you have a custo sound pack (everyone has Amber), that needs to be updated as well once the radio has 2.2 of opentx.
An updated version of Amber can be found open-txu.org

Updated my X9D+ to 2.2 V8/ It works with quad, but none of the somulatiprs (freerider, liftoff) can see the radio. Why it is so?

Sorry. Reflashed it with “masstorage” unchecked and it is ok now.

Hi Mikhail,

but with massstorage unchecked, are you still able to access the content of the sd card via your pc with a usb cable? Because with OpenTx 2.1.9 I am now able to access the sd card via massstorage AND use it in freerider simulator…
