## Bug fixes <a href="#bug-fixes" id="bug-fixes"></a>

* Modem configuration reports an unknown error in AMC when the PUK code is required.
* When the user inserts his PIN code in the modem configuration while there is no signal reception, the modem timeouts at some point and then never regains connection.
* Skynode SD card does not mount after the initial formatting.
* Local updater not handling the device reboot properly, resulting in hanging update process forever.
* Partitions are sometimes not mounted properly after a Skynode is flashed for the first time.
* Skynode booting too fast, causing the kernel to try to mount the eMMC too early in the boot process, leading to a kernel panic.
* MAVLink packets not being automatically broadcasted when connected to the Skynode Wifi AP if the Ethernet netmask is not set to default. This is a specific issue to setups where one changes the Ethernet netmask.
* In the local updater page, during an update, opening the Suite URL causes the update to stop.
* In the local updater, the update aborts before the FMU firmware binary is flashed.
* All Skynode user LEDs get turned on while booting.
* Some Sony A7R parameter values for ISO, EV and WB are missing, causing inconsistencies in the UI if the user selects one of these values manually from the camera.
