Cannpt switch on radio to the firmware update mode.

Post by m0iga » Sat Jul 17, 2021 3:42 pm

After installation of GD-77_V4.2.6.sgl I cannot enter into firmware update mode (SK1 +SK2 + turn on). Radio blinks 4 times with a green diode and starts normally as usual.

Help please with any idea how to fix it?

That is not a version number of the OpenGD77 firmware, its an official firmware version.

Under some conditions, it appears that the official firmware deliberately prevents people upgrading to the OpenGD77 or other official firmware version.

We have no idea whether this is by-design by Radioddity or a bug in their firmware.

If the official firmware has cleared the update section of the ROM, the only way to update is to connect a hardware programmer to the PCB to installed a "modified" bootloader

We suddenly seem to have several posts from people who have the same problem.

So I'm trying to understand why this has happened.


Can you tell me why you installed the official firmware.

Did previously have the OpenGD77 firmware installed and then need some feature like SMS that is not available in the OpenGD77, so you installed the official firmware ?

Or did you think it was necessary to install the latest official firmware to use the latest OpenGD77 firmware ?

Thanks

Roger

Hi,

And which tool did you used to flash this SGL ?.


Cheers.

Because of a wrong understanding of this text below.
To use the OpenGD77 firmware with DMR functionality, must manually download and unzip the official "Firmware and software" package and extract the GD-77_V4.3.6.sgl file, so that the Firmware loader can merge the OpenGD77 firmware with the codec from the official firmware
Poor English knowledge sometimes hurts. :)

I thought that zip from the official site (HAM EDITION) is an open firmware released in cooperation with the producer and I have to upgrade every upper version.

OK.

I will need to add a note that the official firmware should NOT be installed. It is only used for "patching", which is the process off adding parts of the official into the OpenGD77 firmware
