Because Radioddity do not seem to maintain an archive of all the firmware versions that they have released for the GD-77 I have decided to add those files an existing GitHub repository I created some time ago to document various aspects of the GD-77
The firmware file I have copies of, have been uploaded to
This includes versions not officially released and versions which have been subsequently withdrawn
3.1.0 was subject of a soft launch and then removed
3.1.2 seems to be a pre-release / beta, which for some reason has not been released as an official version, despite it being soft-launched to various places, several weeks ago.
I’ve also included the updater exe and its support file, as this works with all firmware versions.
I know there were other versions, with 2.x version numbers but I don’t have copies of these, and some of them were very buggy, and withdrawn by Radioddity.
However I will try to get hold of these missing version, just so that a complete record is kept, as it may eventually help us jail-break the GD-77 firmware.
I have added some more versions.
This is potentially all there ever were, but if anyone knows of any versions I’ve missed and has those versions, please let me know
