If you are on 4.2.2 with an older bootloader and everything is fine, there's no NEED to update it (like me, bootloader was the older 3.x and it worked just fine, adb flashed the zip file directly from 4.1.2 to 4.2.2 with no issues. I decided to bring it up-to-date like the rest and it took less than 10 minutes to prepare & flash it, quick & simple.
To check your verison, restart into bootloader - and it will show your verison on the first screen.
