Hey everybody,  
I am using the WP76xx devices and noticed an interesting behaviour. If I reset the device multiple times, the software on the device resets itself to the initial state. This means all my apps are gone and I need to flash the device again.  
I guess this is the intended behaviour to recover a device if you flash a faulty version during development. In my case, the reboots of the device are intentional.  
Is there a way to disable this behaviour, so the software won’t reset itself after x resets?

Let me know if you need more details.

this is the rollback mechanism:

> **[Updates - Legato Docs](https://docs.legato.io/latest/conceptsUpdates.html#conceptsUpdates_Rollback)**
>
> legato™ is an open source Linux-based embedded platform designed to simplify connected IoT application development

I suggest building the applicaiton together with legato.cwe image:

> [@Application no longer available after a certain time](https://forum.legato.io/t/application-no-longer-available-after-a-certain-time/4546/5):
>
> It is possible to get rollbacks even after an application is marked good. The only way to completely remove the possibility of your app being removed is to compile a new ‘master firmware’ which includes your app.

> [@Flash size wp7607](https://forum.legato.io/t/flash-size-wp7607/3805/35):
>
> you can go to legato-19.02.0/modules/WiFi/wifi.sdef, under “apps:” section, add e.g. $LEGATO\_ROOT/apps/sample/helloWorld/helloWorld.adef [image] Now the new app will be included in legato.cwe. Please also note that the max size for legato partition is 8MB.

if you install some application to module, it will have one more folder.  
After that if you type “update -g” to mark the system to be good, it will only have one directory:

```auto
