I have a herelink v1 controller bought in April 2021, I have fully updated it to the latest version. I also have the original v1 air unit that works well and has been updated through OTA to the latest version.
I am trying to do the same to the 1.1 unit and it keeps getting stuck during the “transfer to airunit” stage.
Also the whole airunit tab seems buggy and it doesn’t always download the fw information and I have to switch between tabs multiple times to get it to load the info.
Sometimes after pressing “download air firmware” the two other options are greyd out forcing me to switch tabs in order for the buttons to eventually be displayed. Not sure if relevant just trying to give as much info as possible.
The reason why I am trying to update it for the last 2 days is because this airunit gives very buggy video through HDMI and we assume its because of the FW mismach.
I did the factory phone reset and still no option for BETA. This controller is almost impossible to get into fastboot mode, so that may be an issue. If this thing does one more OTA update to the same thing, I’ll be looking for my framing hammer lol!
Pressing power + D button won’t do it? You can also plug in the rc to a PC and use ADB to force it into fastboot as well as perform a full reset. Also did you try reflashing the firmware using the flasher app ?
Using the power and D button is hit and miss, but mostly miss. But even with the unit not in fast boot, the flasher app will still find the device and install the firmware. This could be a problem though and maybe why it always forces a ota update to stable. I didn’t realize you can force the Herelink into fastboot with adb. What’s the command?
