Hi all. Go to SystemSettings->About device->Status
Now, is the serial number "unknown"? If yes, did you buy yours from somebody selling units straight from factory (sony=Malaysia)? Is your model NW-F800Series, kernel 126.96.36.199 build 1.01?
That is mean it has not been set correctly in factory. There is boot sequence to be done on newly assembled units like "end settings" that set regions/languages and so on. Yours isn't done correctly by some technician in factory. Don't think anybody will supply sony's service soft here... that is needed to properly boot/reset faulty units.
Also some ppl say new firmware make it dull on bass etc. Did you guys really tried both units old/new soft? I did so and there is a little difference on plus... but the most improvements better flac support (hi res/frq/sq) and some app/sys batt. draining issues.
Best regards and good luck...
