I have flashed my box with the latest image and I got all plugging installed settings, bouquets with channels, etc
But the channels are all grayed out and I get a message in the screen saying "service unavailable, check tuner configuration"

The only way to get all this channels again working is by running the automatic scan

I want to point out that my satellite.xml is restored and I get my three satellites configured astra 19, 28 and hotbird as they were before I flashed the box

The only problem I have is that I have to run the scan again

This is what I wan to avoid because it takes long time running the scanning

Is there any way avoid the re-scanning after the flashing?
