If your still on stock rom you probably will need to use Matty's root tool to load the ota jellybean again.
If you know what files were changed then you could simply grab those from some one and reload.
Or just try one of the many custom roms
What? They told you to 228... that does no good on these phones, thunking if I remember right that 228 is a no no on these phones because of the sim cards.
Try getting them to replace your sim card with a new one.
Not to add insult, but the razr HD or the original razr should have been what you got instead of the m... the m is a stripped down version without the micro hdmi port.
This is one reason its cheaper than the rest.
if you dont like ics is jelly bean going to be that much better?
yes you can switch back and forth as much as you need and wont lose your data, the only thing you would lose is the insurance or extended warranty if you are paying it through verizon
