Starting with a Tango 2 on firmware 1.21 and Crossfire firmware 3.73
First of all download TBS Agent X 2.0.49
SD card content downloads can be found on the bottom of the product page
In my case it was the “Freedom TX 1.2x” download (116MB)
Update SD Card content first!
Open up TBS Agent X. You can just “SKIP” and update without logging in/registering
Plug the Tango 2 and it to your computer, on the T2 screen choose “AGENT MODE (HID)”
You should see this as the next screen
According to the “Update procedure” at the top we can now update the Tango 2 firmware via Agent X
Now click on MANAGE – on the following screen click on FIRMWARE
As of writing this (26.08.2020) there are already newer versions available: choose 1.21
click on UPDATE and on UPDATE again on the bottom of the next screen
Update process / Tango 2 display will show a “download icon”
/!\ Update will stop at the “Restarting device” step. Don’t mind this and go on.
Now it’s time to update the Crossfire MicroTX hardware inside of your Tango 2:
latest Crossfire firmware version is 4.0.2 (don’t mind the screenshot, it’s outdated / 03.09.2020)
on Step 4 the T2 actually restarted itself (female voice) and updating continued automatically
completion 🙂 female voice
After restarting manually the T2 messaged me with a “Throttle warning” and an “SD card warning”.
This was due to the fact that I forgot to update the SD card contents first.
plug in USB and choose –> USB Storage (SD)
When the copy process finished, copy over the remaining five files that you backup’d before
The “Throttle Warning” and “SD warning” messages are gone now. Your T2 is now up to date 🙂
Note: if your sticks show no input, do a calibration again: long press MENU, then PAGE until you’re on page 5 of 6 and the menu shows “Sticks [Calibration]”
