[Q] Certi IMEI: Fail topic

Certi IMEI: Fail and not "Pass"... And "Not registered on network". How to fix it? My IMEI is right.

It started with the OzcanRom 6.3, come on ...

I bought a Galaxy S4 already with the official rom Kit Kat, worked all right.

I did not do backup of IMEI and installed the OzcanRom, then the IMEI was null or generic, since I can not remember more ...

So I sent the phone for assistance with official rom Kat Kit installed, and failed to rewrite the IMEI this

rom ... I was asked to take the phone with ROM Jelly Bean (4.2.2), this worked, IMEI returned.

But I wanted a more updated Android, so I made up the IMEI, I have several here ...

And installed the official rom new Kit Kat ... The IMEI was generic ... I installed several modems and the original IMEI not

back ...

Then restored the original IMEI EFS Professional, IMEI returned, but with network problems ... Only Call

emergency was allowed. I noticed that appeared a warning of a second, a blue square, saying something about

related to "Factory Mode" ... But it was so fast that he could not take print screen ...

So I ended up going back to OzcamRom again, just to be more beautiful.

So, I found that calling * # 0011 #, IMEI appears CERT: FAIL ...

And I found a command that phone functions return the first install the DDUAMDK modem, dial * # 0011 # -> Back -> 8-

1-5-5 -> END, disco * # 0011 # -> Back -> 8-7-3- [1-2] -> END, then give it to make and receive calls, access the internet

and receive SMS, but can not send SMS.

Anyway, it's very annoying to have to get by dialing these numbers whenever I restart the phone, and is also bad no power

send SMS!

Is there any way to fix this?
