OK

Send it back and buy a different radio

As long as I see my refund, that is what is going to happen. It went back as an RMA today.

VK3KYY I only have one, they sent me an RMA to return the first one which I couldn't even enter my Radio ID into. The replacement was clearly a used item (I bought open box as no new ones were available) as it had all sorts of data programmed into it including a radio ID. F1RMB I did try a factory r...

So I'm stuck with the same issue. I'm following the instructions here https://www.opengd77.com/viewtopic.php?f=5&t=1770 but at the point where it says "Turn on your transceiver in bootloader mode (SK1 + SK2 + power on)", it always boots up as if the SK1 & SK2 buttons were not pressed. I tried: 1. un...

Thanks for the reply. Radioddity lived up to their excellent reputation and sent me a new (open box) GD-77 radio.

I have confirmed I can read and write from/to it using the Radioddity CPS so now I'm going to try installing Open GD77.

Either one of the buttons is defective or the official firmware has trashed itself. The official firmware has a bug where it erases some of the copy protection data, and this prevents the radio entering Firmware Update mode. However we never heard of the copy protection being trashed in a brand new...

Daniel, Thanks so much for your detailed answer. From what you're saying it seems that, for whatever reason, my GD-77 won't go into programming mode. I could make a video but the start up sequence appears to be the same whether or not I hold down the 2 buttons; after 10 seconds, "Factory Init..." is...

So, when I try to put the GD-77 into programming mode:
1. Does it normally stay in programming mode for 5 minutes or more?
2. Does it normally appear in Device Manager as a port?

Just put the radio into firmware update mode, and install the firmware It seems my radio doesn't want to go into programming mode, maybe I have a bad cable? If I power it up with the 2 buttons under the PTT pressed, it blinks the green LED slow, fast, slow (with the display blank) and then boots as...

I'm trying to change my GD-77 to run on OpenGD77 firmware but despite holding down the 2 buttons under PTT as I switch on, Open GD-77 CPS never sees the radio. I watched a Youtube video where a guy demonstrated doing the firmware upload from OpenGD77CPS, he said the a radio was already connected. Is...

I found this walk through guide and was trying to follow it. When I checked the menu of my virgin (open box) GD-77, it says it's Soft V4.02.06 so I thought this may be the issue as the .sgl file that Open GD77 asks for is V4.3.6 So I tried to follow the author's instructions on how to update but whe...
