TBS Crossfire- Emergency Update
The TBS Crossfire updates his receivers wireless over the air.
But sometimes this update can get interrupted and the receiver does no longer react to any bindings.
Just in case this happend, there are several ways to get the receiver back to live.
Crossfire FW < 2.24:
- TBS Agent – Download
- Core Pro or
- FPVision or
- Crossfire Diversity Receiver
- BST Wire
Crossfire FW 2.24 or newer:
There is nothing extra that you need.
Background for FW 2.24
Since FW 2.24 TBS has changed the boot loader completely.
The Micro and Nano Rx stores the firmware inside and can flash itself just by the push of the button.
Important: to use the self-update function you need to flash 2.24 (or newer) without any problems or interruption.
The receiver will always install the latest (“golden”) firmware that has been flashed correctly. Right now (03/2018) it’s V2.24 – not the one you had installed before!
As the the diversity receiver got a USB connection you can flash it directly from the agent.
Just hold the “Bind” button and connect it to the pc.
In the Agent it will be discovered with FW 0.00 – just hit “Update” and the Agent will do the rest.
Micro and Nano receiver
FW < 2.24
As the micro and nano receiver both ain’t got a USB connection you need a TBS Core Pro, TBS FPVision or a TBS Crossfire Diversity receiver in order to flash it.
Just connect the receiver to the BST device via BST cable.
Important: only the Core Pro/ FPVision can provide voltage to the BST port.
If you want to use a Diversity Rx you need to power the Micro/ Nano Rx separately.
With Core Pro (FW >2.03) or Diversity RX
To get the receiver ready for the emergency Update you need start the Rx in boot loader mode.
This means that you have to hold the “Bind” button while powering it up. You also need to start the BST “Master” device (Core/FPVision/ Diversity RX) the same way.
On the Diversity Rx it’s the “Bind” button, on the Core Pro and the FPVision the “Menu” button.
This can become a bit tricky as you have to hold both buttons and plug in the USB cable – but it’s not impossible 😀
The receiver shows the boot loader mod with a fast flashing green led.
If your Rx is already stuck in the boot loader mode, you don’t need to power it up and hold the “Bind” button.
Now the Agent just shows the device which is directly connected to the pc – which is normal!
When you hit the “Update” the Core/FPVision/ Diversity RX will be flashed first, then the update for the Micro/ Nano RX will start.
With Core Pro/ FPVision (Fw 2.03 or higher)
Since 2.03 the Core/FPVision auto-detects if the BST -connected receiver is in boot loader mode.
Therefore you don’t need to hold the “Menu” button – only on the receiver (linke before) to flash it.
Crossfire with FW 2.24 or higher
If you successfully flashed your receiver with 2.24 or newer your Rx got his own emergency update stored inside.
To start the self-recovery you need to hold the “Bind” button while powering the receiver up.
Now release the button for a second and press it again for 10s.
The Receiver will start to flash fast green for a few seconds ( 10-15 sec in average).
If he is finished the led starts flash slow again and you can bind him like before.
- If you use FW 2.24 you need to set you region to “open” in order to bind/ update the Rx over the air. There is a bug which will interrupt the update if you’r in a region lock mode
If you have not flashed your Crossfire for a while this can result in a big different in the firmware versions. to avoid problems or bricked receivers a factory reset on the Rx and Tx can help
