Originally posted by G and T More good news, Godox has released new firmware updates for some more strobes, AD600 strobes, AD400 and now AD200 strobes are now compatible with Pentax X TTL.
One more addition: the non-Pentax
V860II have also received a P-TTL compatibility firmware update.
So, only the AD360II and TT685 to go. (The TT350/V350 mini speedlight, and X1R receivers don't do cross-brand TTL).
If you haven't done a Godox firmware update before, you need a micro USB cable, the appropriate firmware update application, and a Windows box to run it. There are two update apps: G1 for all the pre-AD200 lights, and G2 for the AD200 and later lights. So, the AD200 and AD600 Pro requires G2, and the V860II, AD600, and AD600M require the G1 software. You can download the G1 and G2 installers from
the same website that has the firmware files.
If you are on a Mac, a virtual Windows machine or
Bootcamp Windows installation will work. If you want to do this for free, you could try using VirtualBox and a free developer's 90-day Windows VirtualBox virtual machine from Microsoft, but I never had great luck doing that.
You can also use
the Adorama Flashpoint firmware website and use their F1/F2 apps and firmware download files, but they sometimes exceed their Dropbox download limits, and often don't have the files as quickly as the Godox site.
On the AD200, make sure you use the micro USB port near the power switch for the update;
not the USB-A port that's for plugging in an FTR16 receiver if you want to use the old 433MHz Godox system. If it doesn't work, a lot of folks have found that switching micro USB cables can get things going; some micro USB cable cannot transfer data but are only for charging devices. If there are Chinese characters in path names, deleting them will fix any issues with using those files on a non-Chinese system.
