Hi all,
As you may know, the original LONG case Anytone AT-5555Nii radio is now discontinued and has been replaced by the new SHORT case AT-5555Nii radio.
Although the LONG case radio is discontinued, an updated AT-5555Nii LONG CASE firmware was worked on in 2024 that adds many new features, however it was not (and will not be) officially released as there is a potential that some early versions of the long case radio may be incompatible due to component changes that were made along the way.
However, with some clear points and caveats, I can share this BETA firmware.
Please note: This is BETA firmware and may not be compatible with your radio, particularly as it has not been fully tested on all LONG case versions. By choosing to install this firmware, you accept all associated risks — including the possibility of rendering your radio inoperable. Installation is entirely at your own risk.
There is no support available from Qixiang / Anytone for this BETA version. Do not contact them for assistance. Do not attempt to install this firmware on other brands.
If you fully accept these conditions, the attached WWDX BETA firmware and CPS is available for you to try.
Change log:
