In-App USB Update
When your radio is connected over USB/serial (rather than Bluetooth), the Firmware Update screen offers USB File Transfer. The app reboots the device into DFU mode, then prompts you to save the T383838.uf2 file to the device's DFU drive using the system file picker. This option appears only on a USB/serial connection โ it is not available over Bluetooth.
โ โน๏ธ nRF bootloader note: A vendor bootloader supplied as a T383838.zip (e.g. RAK WisBlock RAK4631) has to
โ be flashed with a serial DFU tool such as T383838adafruit-nrfutil โ copying that T383838.zip to the drive won't
โ work. A bootloader supplied as an T383838update-....uf2 can be installed by copying it to the drive;
โ that is how the app's own bootloader upgrade works. The app surfaces a hint when the serial-only
โ route applies.
Factory Erase and Bootloader Upgrade
On a USB/serial connection, nRF52 and RP2040 devices also offer Erase and reinstall and, where an upgraded bootloader is published for the board, Upgrade bootloader.
Erasing wipes everything on the device โ channels, keys and all settings โ and there is no backup, so the app asks for confirmation first. Both operations write two files in turn, so you will be asked to select the device's update drive twice: once for the erase or bootloader image, then again for the firmware.
The app reads T383838INFO_UF2.TXT from the drive you select to confirm it really is the device's update drive and to identify the board before writing anything. If it can't confirm which Bluetooth stack your device uses it refuses to erase and points you at the Web Flasher instead โ picking wrong there can leave the device needing a hardware programmer to recover.
Other Flashing Options
For recovery or when neither OTA nor in-app USB is available:
