Hello guys
I have a problem with my s4 i9500 bought in dubai. I bough a simlock free cellular and after updating it to android 4.3 i couldn't register to my carrier anymore. I tried to downgrade to 4.2.2 and register and it didn't worked anymore, I also tried to install a custom room but it didn't worked too.
Any tips how can i repair it ?
Sim card works on my iphone 4 perfectly, so it can't be it.
P.S English is not my main language so please don't be cruell.

@edit
had network for a couple of seconds and it's gone
Galaxy automatically get incoming calls, after having made the updated 4.3 or after the unlock network by code purchased from fastgsm
I dawngrader has the version 4.2.2 and the problem is to remain the same
I returned to version 4.3 and it's always the same problem
the phone responds to calls alone.
so if anyone has ever had such a problem, I would be very grateful if sharing the solution with me
thank you
How did you update to 4.3?

Hi Guys,
I purchased a Samsung s4 i337ucufnc1 in usa. Have the phone unlocked and am now in South Africa. I have tried to root it and think it is but the wifi is not working. Initially the data was not working and wifi was but after I believe rooting and countless factory resets. It has switched the other way data works and wifi says a security setting will not allow updates, the operating software is the 4.3 version.
I have not found many codes for the samsung s4 i337ucufnc1
how do i get the wifi to work again. Please
Dial *#1234# and attach what appears.

Try to reflash stock rom with odin. Maybe the modem files got corrupted.
Ok just released the phone is not rooted, will this process still work?
Hay there, guys,
I have a Samsung Galaxy S4, which is AT&T branded called i337 which is running 4.4.4 (i337UCUFNJ4)
I have bought it in a used mobile shop here in Pakistan and have tried it with many prepaid SIMs like ufone, Jazz, Zong and Telenor
All SIMs are working fine and don't ask for any SIM authorisation or something like my Verizon i545 used to ask for and gave my SIM
verification error all the time and a Question ? mark was always on the top of my screen.
So what i want now is to install Lollipop on my device as every ROM enthusiast may want.
I know the lollipop has not been made available for my device till now but i have read here;
http://forum.xda-developers.com/galaxy-s4-att/general/install-i9505-tw-5-0-i337m-t3056176
and i know that i9505 and i337 are very very same in the hardware build so i think it is right to say that we can install i9505's firmware on it.
SO if any guru/dev having been working on it can please show me a way.

Not possible at this moment.
Hello,
Please, need help.
I hope I put my concern right place now.
Here is my problem.
I bought used a Galaxy S4 Sprint SPH-L720T Lollipop under 5.0.1 to use in Benin, west Africa. The phone worked well but there are three days my son seems to have made improper handling including a reset in firmware update he said, and after this manipulation, the phone no longer recognizes any SIM card. "Invalid SIM" is the message i got since.
I would then ask if there is a possibility to unlock SIM myrself.
I read somewhere that it is possible on android 4.4.2 so I'd like to know if there is a possibility to downgrade from lollipop to 4.4.2
Thank you
