A new beta build has just been pushed as OTA, with heavy changes to the Wifi stack. All feeback welcome.
To install it by OTA, the beta updater is required, which can be installed from here: beta/UpdaterBetaIode6v2.apk · master · ota / ota · GitLab
That beta updater can be uninstalled at any time, to come back to the stable channel (in App info, uninstall updates).
It is also possible to download and sideload it (https://gitlab.iode.tech/ota/betas/-/raw/master/iode-6.6-20250803-brax3-ota.zip) via adb from a computer in recovery mode. To boot in recovery mode, press volume up while powering on or rebooting the device, start Recovery, then Apply update, and Apply from ADB. Sideload with the command: ‘adb sideload iode-6.6-20250803-brax3-ota.zip’.
