Can anyone help? SIM not recognised

After unrooting my gt i9500 with stock rom 4.4.2 my sim is not recognised. (Insert SIM) is displayed. I rebooted several times but it is not fixed. can someone help...please???
can you check if you have imei and basseband by going : Settings, About Phone?
if you have baseband and imei then your sim card reader is broken, if you dont have those then you did not flashed correct files for your phone.
IMEI is null and baseband is unknown...can you help me further???
you need to flash the stock firmware from kies or you need the correct modem to flash via odin. search on xda for it.

No sim card detected!

So I have note 4 n910h and I root it and flashed SIXPERIENCE rom. When I open the mobile network, I saw a LTE option and then I clicked it(my sim card has not been upgraded) after that there's no signal and I can't revert it back. I rebooted my phone, factory reset using TWM and flashed this rom again and it can't detect my sim card please help ASAP
Never mind, i fixed it by restoring to the stock rom. And how do i close this thread?

I think you have flashed wrong version of firmware. Try flashing different version.
when i flash it with kies it freeze at optimization of apps 5/24
it tells that my original firmware should be Spain PHE
what if i put a Spain PHE 4.4.4 firmware ?

unknown IMEI/ no sim detected. ipv6 fail

This is my first Nexus and unlocked device using a sim card, I'm on sprint so I'm not to familiar. But I tried restoring my backup of stock rooted and it booted up with no sim detected. I tried restoring my EFS and using the dialer codes but when I ran a ping test, it said ipv6 fail. If I flash stock images would it fix the unknown IMEI issue? Any help would be appreciated. TIA
