Yes, it is changed to region “U” which means you can access high gain - as others have said, from there you can change to any other region with the rockbox tool - the only thing to say is that you don’t need to reset the player if you manually switch region - just force restart it (hold power button for 8 seconds)
Only the R version as it does a factory reset. The non R doesn’t change anything
