    Hi,
    When updating my Crossfire Tx from 2.24 to 3.23, the update process halted on “Writing Update” and the transmitter continued to flash green.
    I unplugged the USB from the transmitter after a few hours and now when the transmitter is powered on, it flashes green as if it were updating and shows no text in the display.
    The Agent X can recognize the device, but shows the version as 0.00 and doesn’t attempt to flash any software.

    Is there an emergency update procedure for Crossfire tx?

      hi mitch,
      the “bootloader ” device is what you see when the device got stuck in bl mode/ connected in bl mode – that totaly fine and meant to be like this.
      for now – reboot your pc, update the fw files for your agent (click on the 3 dots, the click on “update firmwares”) – the try to falsh it again

    Thanks so much for this! I had accidentally bricked a brand new crossfire nano by unplugging power during the update (misinterpreted the micro tx LED colors). This worked – but one note, after releasing the button the second time, the green LED kept flashing fast and then went dark rather than flash slowly, so I was worried it didn’t work. But after about 20-30 seconds it started to flash slowly, and success!

    I just want to know whats up with the nano rx losing the bind and not wanting to respond to the bind button. I managed to get it working with the hold when power on then release for 2 seconds then hold till double blink stops but still a pain

      sounds like your receiver is broken. check for some missing smd-parts. might you find a empty spot. if so -> contact the tbs customer service and they’ll tell you which part you need to replace it

    Hi.
    After Binding and updating my diversity nano rx, the rx goes back to bind mode again. Transmitter first says “update ok”, then it looses the connection. Bindbutton is not pressed. Whould this emergency update work to solve this problem?

    Hello,

    I am having the same issue as AirBurner where the LED turns solid green after the double flash pattern. Any update? Thank you

      hi jace,
      sadly no – as he never send me a video or something. but i guess the fw file is corrupted – soul i ave to go with the core pro/ fpvision flashing method

    —— THIS STEP DOES NOT WORK

    Push and hold the button again
    The green led starts to flash in a double-pattern. When it starts to flash rapidly again, you can release the button
    ————
    Rx goes straight into solid green light after a double pattern. I am extremely frustrated having the day ruined by hours of tries to run my quad.

    hello, I tried updating my micro diversity through the core pro bst and agent x with no success. on agent x I can only update to FW 2.07 beta and you say I need to be at least FW 2.09 for the core pro, what do I do? I also noticed your bst pinout for the cable is different from the tbs manual. is that correct?\
    thanks

      hi joe,
      you are right – i got the scl and sda twisted. i’ll update it asap.
      The fw version was related to the fpvision. just use the latest (beta) version for the device to be safe.

    hi. tell me please. I accidentally updated diversity nano rx through agent 2.4. now there is no bind. agent “x” has updated the transmitter to tbc. but there is no way to connect it. I am from Russia, no one has core pro / fpvision here. There may still be restart options. The option with clamping and fast blinking did not help.

    • KamiKatze sagt:

      hi artyom,
      sadly there is no chance without a core pro etc to get it back working.
      you can try to bind(with fw 3.9x or later) and as soon as the receiver will connect – unplug the rx battery. now retry. this CAN save it. but at the end of the day you’ll need a core pro etc to get it back. maybe you can finde one on ebay or cheap or send the rx back to your shop

    I had success with the emergency process update in a Micro RX V2 (couldn’t update by OTA at all), but no success with a nano diversity, I binded using version 2.24 in my transmitter, now it’ is bricked forerver, could you help me please ?

    • KamiKatze sagt:

      hi allan,
      in your case you need a core pro/fpvision/standard div. rx to get it back working.
      if your agent x (not the old one!) runns straight throu the update of the usb device, try swapping scl and sda
