I've upgraded my n7000 to 4.0.3 everything was fine till i inserted my postpaid sim card and said cannot connect to network.I have tried to connect manually and doesn't work as well.
Checked the imei and was wrong 004999010640000 , reflashed it with stock 2.3.5 , restored the original imei everything was ok (with prepaid and postpaid sim cards).
But if i update again to any 4.X.X rom it doesn't recognize postpaid sim but has no problem with prepaid sim cards.
Any suggestion on where might be the problem or what should i do?

Hi,
The problem i experiencing is that when i boot the phone with sim card in it, the imei will come up as unknown. However, if boot with no sim, imei is then correct. phone calls, sms and data all working fine, but if i want apps that need imei, i need to reinstall firmware and install apps before the next reboot. i want to know if there is a problem with my sim (2 to 3 year old sim), the firmware or worst, my phone?
history:
I have recently got a imported SGS (Hong Hong ver) in Australia, using telstra sim.
There was problem (IMEI) at start with the build-in rom as i start the phone with sim in, but i didn't check if imei ok without sim. i then made a /efs backup and upgraded to jpe via kies, which the imei seems to be fine.
i when on flashing speedmod k12 (adb odin), no lagfix, just for the kernel, root and nand backup. didn't bother to check imei. I decided to test out darky's rom, did a factory reset and installed v8.0 slim (no wipe).
right now I'm thinking of flashing back to jpe via odin to see if problem still occur later today. or i should be testing something else?
Thanks

Hi gys! I need your help!!! I run official ICS on my LG P990 with my vodafone sim card.
I wanted to gift my phone but when i put cosmote sim(other network) phone doesnt see it, its like no sim card.
I enter menu to manually change the network to cosmote but says "sims doesnt allow it). Do you know whats happenig? It a hardware faulure or it is locked to a network? I already try (and payed too) to unlock my phone with code with no success.
Please help!!!!!
Is your phone network branded? If so you could download and install an European open stock rom and flash that to get around the network permissions.

It was a hardware error! Sim card reader fails and i have replace it. Now everything working fine!
Now that it works well now, cong! I've meet this problem before and it was cause by the rom.
Hello I have an unlocked samsung ace. I got him rooting and I installed a custom rom. Everything works fine but now I placed a SIM card from another provider. The phone starts completely without error but I have no network. The SIM card is good because he does it in other phones.
Does anyone know the solution?

I was using stock ROM and I was using data network normally . I changed my sim card type and didn't try data network with the new sim
And I changed baseband and my kernel to anc2 after I returned to previous sim it said me change traffic plan and I said yes . but I can't use data network now. And I flashed omni rom and data network didn't work too any idea how to solve this problem note. I returned to previous baseband and it didn't work too mine was ana2
(solved) the problem was with my sim card
Hi, I have xt1079 for about 6 months, and it works well, since the day I used it in low coverage area,
it has Mokee 5.1 build and works in LTE network. And I take the 2nd sim card off while the phone was working, and after that the phone cant recognize the 2nd sim card at all, after a half of hour the 1st sim card lost too.
After rebooting the phone show phone app error...as I can see, in settings menu IMEI information became "unknown".
I wiped the phone and try to reflash the same firmware, but the result was the same. I tried 6.1 firmware, and the IMEI information came back and the phone works , but only in 2g. I mean I set the LTE/ 3G/2G, but it always in 2g network.
If I install LTE only or 3g only - no signal.
If I flash the phone back to any 5.1 ROM it's loose sim cards.
What would you recomend? Flash stock firmware?
I don't do it yet, what do I need to flash stock firmware?
Download the stock firmware for XT1079 and flash it from PC using fastboot. All the process & steps to flash are already available on XDA, just give it a search.
