OpenGD77

hi all i have just got a gd77 its already got opengd77 installed i have tried to link the radio with the opengd77 cps and it doesnt register could it be because the firmware on the radio is 2 years old just to add im using a cable off the tytmd380 i bought it off radiodiddty and they assured me its...

Probably never. As you can see here, the device is only specified up to 480 MHz:

The current model is not yet listed at the FCC. The latest info is from 2019:

Thanks for Your answer!
As I've read in any instruction guides, first step is, to bring the device up to date with the original firmware.
Is it possible to startup from 2.06.03 to the latest OpenGD77 release?
Cause it's an older one, I don't want risk to brick it.

Good evening from germany.

Please share your experiences with a absolute beginner.
Just got an older GD-77 with V 2.06.03 and DSP HRC6000 V 1.2.6
Which update path is useful and possible, straight to 3.2.2 (4.2.8/4.3.3/4.3.6?) or are intermediate steps required?
