if you update a flashed device it will need to be re-flashed for service to work again, unless your device is way back in the 130's firmware version you will gain nothing from updating except to spend some money to get it reflashed, the updates for the 2200 were worthless and did not fix any issue except from 139 to 14x fixed a minor signal issue the all other updates were all a bunch of nothing, you will notice it only addes using new graphics on the user interface that does nothing for making the end users experience any better, they just kinda of ignored the 2200's problems, after all it was the first device of its kind so after the 2200 instead of fixing its problems with overheating and weak signal to begin with they moved on to the 4510L and just forgot about all the peeps who bought those 2200 devices that had probs.
