I finally received the OTA update of Jelly Been and after the install finished i have no sprint service. Could it be my radio as I had unlocked it before and had applied the wi fi tether fix?

Paul, I had ran the bat file from the stock recovery_ns4g_4.0.4.zip you made a few days ago, thus allowing the OTA jelly been install to work.

Any ideas on what I can do? I tried removing the battery and rebooting mulitple times. Still no cell service. Have wi fi connection from home showing and working though no bars and no mobile connection. I double checked under settings "mobile network settings" and data enabled is checked.

It must be the radio right? Is there possibly a radio I could flash to fix it?

Thanks for any help! Really stuck not being able to make calls or send text.

What does your "about phone" say about your radio? PRLF2 if the latest.

If you want it, google has released fastbootable images of all disk images for 4.1.1 on the ns4g

Baseband version: unknown Network: unknown, PRL version: unknown. Could I just flash one of the radios in Clockworkmod?

yes you can flash the radio in cwm or push it fastboot as we did with the stock recovery

Here is a link below to flashable (CWM/TWRP) version of the radios...

You need Baseband D720SPRLF2 from OTA JRO03R

I did a flash with fastboot of the radio from xda. Still no service ;( The dos window said OKAY and it appeared the flash happened. I could not boot in CWM Recovery as got the red arrow error when I tried. Any other things i can try? I'm getting super worried as I can't get service to make calls or text. Do I need to go into Sprint? Do a full reset somehow?

I had the same issue trying to apply the tether fix only after I had put JRO03R-v1.1-rooted.deodex.signed.zip from hlxanthus (thank you for the zip). What i didn't realize is the fix must already be there (why didn't I check first.....dumb.....lesson learned), because every time I applied the tether fix I would loose my radio. I tried just flashing the latest baseband to no avail. I then re flashed JRO03R the current baseband (during the same recovery) and everything was right in the world again and I had tether. I'm sure its the tether fix that is causing the radio problems.

I'm using CWM 6.0.1.0

How did you "I then re flashed JRO03R the current baseband (during the same recovery)" ? I can't get into CWM. I can only fastboot flash. Is there a way to remove the tether fix? I'm sitting here checking this page by the minute as I really need to use my phone to make a call and would love to get it back up!

[Paul627g]

Yes this as mentioned above... The tether fix your using is probably outdated and is causing issues...

[mbsprinter]

Unfortunately, if you don't have CWM ( that's the only way I know how to manipulate this phone) I'm not sure I can help you any further. It just sounds like you need to start fresh from ICS then jump back to JB without messing with the tether fix .

I'm back up and running with a working mobile network again too. Had to do a full restore and wipe my phone. Was able to use the guide, and "Unroot/Restore to Official Jelly Bean v4.1.1 (Thanks hlxanthus)". Thanks to Paul627g and mbsprinter too.

Sorry to hear you had to do the full wipe but at least it was better than a brick or some other device ending illness.
