+# Meshtastic Firmware Hacks
+
+### Custom Boot Logo & Message
+- Download & install [PlatformIO](https://platformio.org/platformio-ide)
+
+- `git clone https://github.com/meshtastic/firmware.git`
+
+- `cd firmware && git submodule update --init`
+
+- Use [XMB Viewer](https://windows87.github.io/xbm-viewer-converter/) to convert an image to XMB
+
+- The data from this goes in `firmware/src/graphics/img/icon.xbm`
+
+### Custom boot message
+- Navigate to `firmware/src/graphics/Screen.cpp`
+
+- Find & replace `const char *title = "meshtastic.org";` with your custom message.
+
+### Custom screen color
+ - Navigate to `src/graphics/TFTDisplay.cpp`
+
+ - Find & replace `#define TFT_MESH COLOR565(0x67, 0xEA, 0x94)` with your custom color.
+
+ ### Custom alert sound (for T-Deck & devices with a buzzer)
+ - From the mobile app, click the 3 dots on the top right, and select `Radio configuration`
+ - Under `Module configuration`, select `External Notification`
+- Scroll down & you will see a `Ringtone` option that takes [RTTTL](https://en.wikipedia.org/wiki/Ring_Tone_Text_Transfer_Language) formatted tones.
+
+As far as I know, at the time of writing this, the onyl way to change the Ringtone is from the App...
+
+
+ ## Compile & flash firmware
+ - Select `PlatformIO: Pick Project Environment` & select your board.
+ - Run `PLatformIO: Build` to compile the firmware.
+ - Place device in DFU mode & plug in to the computer
+ - Do `PlatformIO: Upload` to send the firmware to the device
+ - Press the RESET button or reboot your device.
+
+ See [here](https://meshtastic.org/docs/development/firmware/build/) for more information building & flashing custom firmware.

 The hardware I am experimenting with: [Lilygo T-Deck](https://www.lilygo.cc/products/t-deck), [Lilygo T-Beam](https://www.lilygo.cc/products/t-beam-v1-1-esp32-lora-module), [Heltec Lora 32 v3](https://heltec.org/project/wifi-lora-32-v3/), and [RAK Wireless 4631](https://store.rakwireless.com/products/wisblock-core-modules?variant=42440631419078)
 
+## Notes to self & developers
+- The node id formula is: f'!{hex(node_num)[2:]}'
 
 ## Hardware & Software related Issues
 - T-Deck must have Wifi turned off when going mobile. Upon leaving my house with WiFi still enabled, the UI & connection was EXTREMELY laggy & poor. Couldn't even type well...
