Godox G1 “Connect Failed” Issue
Yesterday I tried updating the firmware on my Godox X1T-O and TT685O flashguns. While the X1T-O went well after realising that the controller needs to be powered off with no batteries. The same couldn’t be said for the TT685’s.
I had used the same USB lead which I know is fully wired and not just a charging cable. However, no matter what I tried doing I couldn’t get the TT685’s to update using the Godox G1 updater. I confirmed that I could hear the “chimes” when the flashgun was connected to my Windows 10 laptop but as soon as I selected the TT685 firmware and it confirmed as ok, clicking “Connect” would instantly bring up a “Connect Failed” error.
Searching the web brought up the usual suggestions of either trying another cable or running the G1 updater as an Administrator. Unfortunately, neither of these worked in my particular case and some of you may know that wile Godox make some great gear their support & documentation leaves a lot to be desired.
Thankfully the Flashpoint rebadged units that are sold by Adorama have better support. So for those of you Windows 10 users the solution is to do the following:
- Disable “Secure Boot” in your BIOS if you have a UEFI BIOS on your PC.
- Turn off driver signing inside Windows 10. Open a command prompt as Administrator and type in the following command: “bcdedit.exe /set nointegritychecks on” and press “Enter”
- Once you’ve completed updating your firmware you can turn on driver signing back on if desired by typing the following command: “bcdedit.exe /set nointegritychecks off”
- Make sure to run the installer AND the program (from the icon) by right clicking and choosing Run as Administrator. Only connect the unit by USB to the computer AFTER running the installer and opening the program.
- Make sure all units are powered off with batteries removed before trying to connect them.
- Don’t forget to press the lightning button to discharge your flash before connecting it to your PC!
I hope this helps any of you Godox users who are puzzled/losing the will to live over this issue.
