Radio presets lost when switched off

[Benoit]

Hello,

Every time I switch off my S9, the radio settings are deleted.
On startup my channel presets are lost.

Do you have any idea about this problem?

I confess, I played a lot with upgrades and downgrades....
I'm now back to original device 2.50 firmware, after deleting every file under system.
It solved every problem on my device (lost of configs, of radio settings, and reinit on every power on...)
