@indicat,

That requires some serious in depth knowledge of the platform and access to the source (not all of which we have) and needs to go through the firmware team, you need to push that to your distributor to raise a proper ticket as it is beyond the forum to be able to help with that.

Also the above information is probably not enough to be able to come to a conclusion, you might need to get a full dump from the unit (couple of hundred MB’s.

One thing I would say is move to the latest firmware for your unit.
