Hi Sebastian,

I confirmed your board was successfully recovered with our solution.

The new version 10.3.0 will protect this kind of issue. Once it happened before installing 10.3.0, our support team will guide how to fix it on our devzone.

Thank you for your patience and providing the kit. It was very useful.!

BR,

Brian

Hi Sebastian,

Thanks for your time last Friday.

This issue has been discovered that affects modem f/w programming of devices with nrfjprog/nRF Connect Programmer. The modem is vulnerable to file system corruption during a time window in the update process, and unfortunately, the nrfjprog issues a reset that sometimes hits this window. This can cause memory corruption of the file system.

-. We will release new version(10.3.0) of nrfjprog 'soon' that does not issue the reset.

-. And also we will make a modem f/w image that repairs the broken file system on affected devices 'later'.

I will let you know when the 10.3.0 is officially released on our web page.

Thanks for your patience.

BR,

Brian
