Hello guys I am from chennai. I used to have 3G signal signal in my ecliars and official xxjp2 rom. But in the custom rom I am not getting any 3G symbol at all. And no data network connection.

Did you ever get any help with this? I have been reading the Note 2 post, and I think I may have read the whole thing from where they started talking about the S4 till the end, as well as about half the rest. I cannot get my S4 to get data working at all. I am in need of the Nandroid backup as well, unless you got it and it didn't work for you.

Nope no one seems to want to help ..but I have gotten the 3g function to work on the s4 by flashing the correct aaa passwords still cannot update profile or prl

I was coming from a TP2, but that data didn't seem to work. Where you using the same phone, or something else?

I was using an boost incognito as a donor im the settings under data connections set it to cdma only tjats the only way the settings from the donor will work on the s4

Thanks! I had made it CDMA only, but not in there, in ##DATA#.
You know what, this means that I may have gone through all the headache for nothing. I'll start over and we'll see, it may all work without need of *2/activation.

Yeah the *2 method will not work unless the s4 was previously activated on a sprint account

Well, changing the data to CDMA didn't work either. I also have been reading on Nandroid backups that may help with this, and I think what we would need is the carrier. Someone said that EFS is ok to share, but carrier one would have user specific data once it has been activated. So, I guess my fix will be to get them activated on a Sprint line first, then go through the flash.
Thanks for your help!

As you said that you have flashed a custom ROM and now on stock rom,
Check whether you still have the IMEI #.
Also try insterting the Sim card on another device to check if Sim working, if working then try doing a factory reset.
Also once factory reset done as go in Setting-More Networks-Mobile Networks-Access points-Reset to default.
Try the above steps and let me know if problem still persists.
Dont forget to click the Thank button:good:

Might be a sim card problem. You've probably taken it out and put it back in? You might have to get a new one
