Hello, I was trying to stop some apps that were preloaded on the card, and the mangOH red crashed : - I was disconnected of the ssh mode of the mangOH red . - I noticed that all the apps I had installed previously disappeared ( thanks to an _app status_ command ) - the firmware of the module WP8548 downgraded from SWI9X15Y\_07.12.14.00 to SWI9X15Y\_07.12.09.00 - Also the mangOH card and the WP8548 module were overheating before the crash Is it normal that the firmware downgrades when there is a crash ? Thank in advance Louis ---

Hi @Louis96 , Which applications did you stop from running ? ---

@Louis96 How did you install the apps? Did you use the `update` command or `fwupdate` command? The former command installs as an overlay which can be rolled back to a base image depending on how many restarts occur.
