This project allows users of Hytera radios to program them using a cross-platform program written in Rust. It has been tested with the following radios:

• PD785G
• X1p
• MD785

Editing of the following codeplug features is currently supported:

• Contact List
• Digital Channels
• Analogue Channels
• Zones
• Roam Lists
• Scan Lists

Use of this software is at your own risk; the program is in alpha and could brick your radio! Be sure to take a firmware backup of your codeplug memory as the first thing that you do. Boot your radio into firmware mode, connect the programming cable and run:

$ hyrps fw-dump-cp-memory cp-backup.img

If you need to revert, you can restore by entering back into firmware mode, connect the programming cable and running:

$ hyrps fw-write-cp-memory cp-backup.img

A good first place to start is printing out your codeplug:

$ hyrps print-codeplug

Hyrps doesn't currently implement an interface to edit codeplugs outside of it's software. You need to compile your own version which contains your own codeplug. See src/custom_cp.rs and the function mutate_cp for an example. Once complete, you can write that new codeplug to the radio with:

$ hyrps write-custom-codeplug

For anyone wanting to do some more advanced work with their codeplugs or perhaps some codeplug image reverse engineering (contributions welcome!) the following features may be useful:

You can get a dump and write a codeplug image from the radio without having to use firmware mode with the dump-cp-memory and write-cp-memory commands. This can be useful since most of Hyrps' commands take an optional path to a codeplug image which can be read as an alternative to reading from the radio.

The Hytera codeplug image comprises of numerous sections, each of which has a header, a payload and a mappings table. You can use the print-sections command to traverse the sections and print out the headers:

$ hyrps print-sections

As stated above, sections wrap one or more binary payloads. You can get hyrps to dissect each section, apply the translation table and dump the binary payloads to a file:

$ mkdir out
$ hyrps disect out
$ tree out
out/
├── 0x025C/
├── 0x025D/
│  └── 0000
├── 0x0253/
│  └── 0000
├── 0x0254/
│  ├── 0000
│  ├── 0001
│  ├── 0002
│  ├── 0003

[...]

Here each folder beginning with 0x is the section type and the files under are the in-use payloads.
