LS Advice again please

I think the distinction needs to be made whether we are talking about using . overpowered multiband transceivers after society drops out or as using it as a regular comms device - right now in the present.....

One thing that needs to be made clear is - if we can pinpoint an all singing all dancing more powerful multiband transceiver can we alter the firmware of the device by using software - to enable only 4W on the UKFM freqs ?
...and alternatively - allow full power elsewhere.

This would enable us to use the transceiver as an everyday UK and euro compatible transceiver - with the ability to reach HAM with more power allocated to those freqs ?

On mobile phones that I've 'flashed' all sorts of new options sometimes become available , I've never 'unlocked' a transceiver before, so I don't know what - typically - it allows you to change , is it a basic freq unlock or can you alter other things like I mentioned previously ?
