Recover missing SIM toolkit icon on Android if it has disappeared

My SIM toolkit suddenly disappeared and after try a number of options, this is what worked for me on an SGII, Android 4.2.2

Enable SIM lock - (make sure you know the default SIM lock code before you do this, check with your operator)
Reboot phone.

That's it.
Apparently on some phones it can reappear by enabling flight mode and disabling it but that didn't work for me.

Hope it helps. Let me know if you found any other ways of getting it back.

Corrupt files on USB - incorrectly sized USB stick

If you're like me, at some point you've probably been duped and bought a USB stick pertaining to be a certain size, only to find out it isn't. They frig the size thats reported and sell it as a higher capacity drive. GRRR!

Anyway, if you can't get your money back (or can't be bothered), you can still make the drive useful using these commands which overwrite everything on the drive and allow it to be writeable. (I did this on a cheap mp3 player as well and it fixed the problem of not being able to play certain files.)

Open a command prompt and type the following commands. (Make sure you select the correct disk number !)
If you're not sure which is the correct disk, check the size or use Disk Management (Right click My Computer > Manage > Storage > Disk Management)

diskpart
list disk
select disk #
clean
create partition primary
select partition 1
active
format quick fs=fat32
assign
exit

I've reposted this from here which was about fixing this issue with a USB stick that had been formatted by an Xbox because as my problem had a different origin.

Convert VRO to AVI (or other)

Found a free utility for this: MPEG StreamClip at www.squared5.com.

It doesn't seem to do VRO's with multiple chapters and it's very limited in the output due to it using Apple filters predominantly.
I used output to AVI, H.263 with mp3 stereo.
I would have preferred H.264 but whenever I used that, nothing played in Media Player.
