To support users by using the md380tools or the resulting patched firmware a Google Group is public opened and reachable via https://groups.google.com/forum/#!forum/md380tools. No extra registration should be necessary. You could also feed it via e-mail at [email protected]. So feel free to put in your questions into it!
A few of us are also on the #md380 IRC channel on Freenode.
A helpful site is available at http://md380.tools/
There are also some related groups you may find interesting:
This repository contains tools for working with codeplugs and firmware of the Tytera MD380, which is also sold under a variety of different brand names. The codeplug format is sufficiently similar to the radios from Connect Systems (CS700, etc) that these tools might someday be made compatible.
Client Tools:
md380-dfureads and writes MD380 codeplugs and firmware.md380-toolcommunicates with the patched firmware. (Fancy stuff!)
Development Tools:
stm32-dfumodifies firmware for jailbroken devices. (No longer required.)md380-fwwraps and unwraps devices firmware.md380-gfxmodifies firmware graphics.
The patched firmware is known to work on the following devices:
-
The "D"-Version (NoGPS) for radios without GPS
- Tytera/TYT MD380
- Tytera/TYT MD390
- Retevis RT3
-
The "S"-Version (GPS) for radios with GPS
- Tytera/TYT MD380
- Tytera/TYT MD390
- Retevis RT8
Both types of vocoder (old and new vocoder radios) are supported.
The DMR MARC user's database required a 16 MByte SPI Flash memory chip. In some VHF Radios is only an 1 MByte SPI Flash installed.
| Name | vocoder | GPS | exp FW | original FW |
|---|---|---|---|---|
| MD-380 | old | N | D02,D13 | D02,D03 |
| MD-380 | new | N | D02,D13 | D02,D13 |
| MD-380G | new | Y | D02,S13 | S13 |
| MD-390 | new | N | D02,D13 | D13 |
| MD-390G | new | Y | D02,S13 | S13 |
- RT3 = MD-380 (old)
- RT8 = MD-390G
This software is licensed in exchange for two liters of India Pale Ale, to be delivered at a neighborly bar, preferably one without televisions.
Tytera's firmware is of unknown license and is not included in this repository. We use a heap-less printf library under the BSD license.

The MD380 uses a custom variant of DFU that isn't quite compatible with the spec. Their code seems to be forked from an STMicro example for the STM32 chip.

This project should work across Linux, Mac OS, and Windows, but has not been tested on all platforms. A separate client, MD380Tool, is under development for Android.
git clone https://github.com/travisgoodspeed/md380tools.git
cd md380tools
sudo cp 99-md380.rules /etc/udev/rules.d/
(The 99-md380.rules file is copied to /etc/udev/rules.d/ in order to allow users to access the radio over USB without having to use sudo or root permissions.)
Turn on radio in DFU mode to begin firmware update with USB cable:
- insert cable into USB.
- connect cable to MD380.
- power-on MD380 by turning volume knob, while holding PTT button and button above PTT.
For non-GPS-models do:
git pull
make flash
For GPS-models do:
git pull
make flash_S13
Turn radio normally on to begin database loading with USB cable
For European users:
make updatedb_eur flashdb
Note: for European users it is probably illegal to use the other method for updating, due to privacy laws. (This is no legal advice, please consult your lawyer to be sure.)
For the rest of the world:
make updatedb flashdb
(The users.csv file located in the db directory must be refreshed this way,
with make updatedb, otherwise it will continue using any already-existing
users.csv file when running make flashdb.)
Anything with md380-tool requires a recent version of our patched
firmware. You can check your version in Menu/Utilities/Radio
Info/Version. If it's a recent date you're good; if it's a number,
you need to upgrade.
To dump the recent dmesg log:
md380-tool dmesg
This archive does not ship with firmware. Instead it grabs firmware from the Internet, decrypts it, and applies patches to that revision.
You can reproduce the patched firmware with make clean dist after
installing an arm-none-eabi cross compiler toolchain. The firmware
and a Windows flashing tool will then appear in
md380tools-yyyy-mm-dd. Alternately, you can flash them from Linux
with make clean flash, after starting the recovery bootloader by
holding PTT and the button above it during a radio reboot.
You can install any of these patched firmware files into your MD380 by
using the respective .bin file with the Tytera Windows firmware
upgrade tool, upgrade.exe, available inside their firmware upgrade
downloads. Here are the steps:
- Turn off your MD380 using the volume knob.
- Attach the Tytera USB cable to the SP and MIC ports of your MD380.
- Attach the Tytera USB cable to your host computer.
- Hold down the PTT and the button above the PTT button (not the button with the "M" on it).
- Turn on your MD380 using the volume knob.
- Release the buttons on the radio.
- The status LED should be on and alternating between red and green, indicating you're in flash upgrade mode.
- Start the Tytera
Upgrade.exeprogram. - Click "Open Update File" and choose one of the .bin files produced from the process above.
- Click "Download Update File" and wait for the flash update process to finish. It takes less than a minute.
- Turn off your MD380 using the volume knob.
- Disconnect the USB cable from your MD380 and host computer.
- Turn the MD380 back on, and you should see the "PoC||GTFO" welcome screen. You're running patched firmware!
Also included is a partial driver for the MD380 in Chirp. This driver doesn't yet support the essential DMR features, but it does handle analog channels and banks well enough to load analog repeaters into your radio.
This driver can't yet communicate with the radio, so use md380-dfu read foo.img to read an image out of the radio, then open it in Chirp
after installing chirp/md380.py as a driver. Once you've made your
changes, you can load the image back in by running md380-dfu write foo.img.

Image editors like GIMP will discard the original comments, but you can replace them by opening the file in a text editor and copy-pasting the comment lines from the original extracted file to your custom image.
There are several boot logos provided that you can choose from by editing
patches/2.032/Makefile, and commenting/uncommenting as you see fit.
The original boot logo is 160x40 pixels, and only 2 colors. This means an image that has the same properties can be written into the firmware as a direct replacement, as seen in the Makefile.
An image with more than two colors requires the "relocate" argument to
md380-gfx. There are examples of this in the Makefile as well.
