We need more info on your issue, also since you are rooted, what method did you use to root, did you create a Nandroid once you rooted, and what Rom are you on, and what recovery are you using ??

Hey there. This is the guide I used to restore my buddy's Verizon Note 2. It has downloads for the Sprint version as well.

Unfortunately, I don't know how to restore the specific items you need but the guide below will get you back to stock presumably with radios intact. Radio=baseband FYI.

So, as long as you have everything downloaded and ready to go, this is a breeze. My advice is to read through the whole guide before starting it. Download the necessary files as you read through.

There is a video to help as well as photos throughout.

For what it's worth, at first glance as to why you are in this sticky situation, it seems you may have flashed a ROM for a different version of the Note 2.

Hope this helps.

After flashing a ROM, the GN2 is unable to activate the radio/modem. The following read "Unknown" in the "About Phone" menu:
Baseband, Network, Mobile Network Type, MEID, IMEI, ICCID.....etc. Basically anything to do with the mobile network.

Problem #2:
When booted up and running, PC will not recognize the phone as usual (unable to copy files to phone).

Thanks
