So one thing that apparently does not work when you haven’t used unlock_critical is automatic OTA update. At least the first one. According to information from the Matrix channel, you need to sideload the first OTA update. But the next should be fine and work as expected.
To sideload the Calyx OTA update do the following
-
download the full ota-update from https://release.calyxinstitute.org/FP4-ota_update-22305011.zip
-
make sure that USB Debugging is enabled in Developer Options
-
connect you FP4 to your PC and run
adb reboot recovery -
when the FP4 has rebooted, the android lying down will appear and on the bottom of the screen it should say “no command”
-
press Power & Vol +. This should open the recovery menu
-
with Vol - select Apply update from ADB. Confirm with Power
-
on your PC run
adb sideload FP4-ota_update-22305011.zip. Your PC will show a percentation progress, your phone will show some status messages. This will take a few minutes -
when finished, the menu will appear. Select reboot now
Phone should reboot into updated Calyx OS
