My Galaxy S4 randomly lost its signal a few days back, since then I have flashed it to Stock Rom, flashed to stock recovery and kernel, did a factory reset, wiped cache and dalvik cache, tried to unlock using the *#0011# method. Still sim card is regonised for a moment then it is blocked after a few seconds. Can anyone help please? Thanks.
Anyone knows how to fix problem??

Just be patient and give the guys here some time, remember that in some parts of the world is midnight right now. Now, I assume you have tried that same sim card in other phones to make sure the problem is not the sim card.
Cheers

Yes, tried that, do you think I should try flashing the modem again? Or maybe I messed something up in the phone service menu when I was unlocking, through the nv_backup menu?

Well, I had the same problem with my s3. I did a factory reset, and it worked. Try flashing the stock rom again, and be brave because you might lose your phone from not flashing right.

What was the source of it? OTA/official update? If so, and if you did not rooted your phone - go to provider/service.
Most likely, your efs partition is screwed up. If you do not have backup - poor chances for restoring it.

Sorry, what do you mean source of it? I usually update my phone over the air by official samsung updated.. All i read is efs partition is screwed only if you root but i never tried to root my phone..

OTA = off the air, so you have the official ROM. In rare cases, efs can be damaged by that. Call nearest Sammy Service Center.

i have one nexus 4 purchased from Ebay. it has
4.4.2 OS STOCK,
base band M9615A-CEFWMAZM-2.0.1700.97
KERNEL 3.4.0-perf-g2cae413 WED nov 20 14:54:28 PST 2013
build number KOT49H
it has unlocked bootloader, rooted, twrp installed.
it is able to show me IMEI number in about phone and as well as on dialer *#06#
now the problem is, when i insert sim card, it show me no service and no signal in status bar.
so not able to use phone.
kindly help me
Flash the latest factory image.
My N7's baseband version is M9615A-CEFWMAZM-2.0.1700.98, so I think you have the 4.3 baseband which is incompatible with the 4.4 roms, that's why you don't get service.

Best solution is try some another "micro sim".
DONT cut it but bring it from your service provider.

From what I know I believe the sim cards can have hardware within 1/16th of an inch from the side, or it might have been 1/8th but yes dont cut the card, um I know it sucks but back up what you can with something like titanium backup, then try undoing what could be the cause, so flash stock rom. With titanium backup you just hit backup/restore then the checkmark in the top right then scroll way down and hit restore apps/missing apps+sys data... if it fixes the problem then great but put a copy of the backup on your computer in case the extsdcard gets wiped too for some reason or in case you have to send it in

i use following method to downgrade
http://forum.xda-developers.com/nexus-4/general/how-to-how-to-flash-factory-image-t2010312
Ill ponder for a while and see if I can brainstorm a solution, ill ask around a bit and see what I come up with,
If your worried about your warranty and your carrier won't help you, I suggest going to best buy and letting the Samsung guys take a crack at it, they have the proper software to find the problem.
OK when you first got the phone was the sim working?
Is it a carrier specific device?
If yes are you using a sim card from that carrier?
Is the phone unlocked or factory unlocked or is it locked?
Was there any thing you did such as flashing custom roms?
I think it may have a bad Imei but I'm still trying to figure that out

dont know if you ever got your issue fixed or not, i had a similar problem the other day on my galaxy s4 i337
i was able to make phone calls and recieve text messages but i could not access the internet through the network, my carrier actually did something that helped but didnt fix it... the technical support team had me turn off the phone and then they erased me from the network, so when i turned the phone back on the phone rebuilt the network through the sim card and for some reason i have better reception now...
i still could not connect to the internet via wifi or mobile network so i factory wiped and installed the stock firmware.
do you have somewhere to go where they can "officially" flash the stock firmware? here in the usa i can take my phone to BestBuy, a large electronics dealer, and they have a samsung area that the people have the tools to do so.
maybe your network carrier can help you, maybe its not a phone issue but rather a network provider issue.

It's a little bit strange but you can try to use an adhesive tape on the side of sim card to prevent a short circuit between contacts and the sim card's metalic tray.
It worked for me.
Hey, I rooted a T-Mobile S4, and used RegionLockAway to get rid of being lcoked with T-Mobile. Any simcards i place into the device, it asks for a simcard pin. When I place the sim card in my Nexus 5, there is no pin and works flawlessly. What can I do? I tried deleting the data of the device and its still there. Thank you

Yeah I went into settings, the only option is Lock SIM card, if I press it, it asks for the previous sim card pin, which I have never put on... Would reflashing the ROM work instead of having to factory reset?

Yes , but i would be the same , if i understood right you are stock , so you have to flash with odin , so you will full wipe the phone to do it.....
Why you do not use an app like titanium back up , back up all your app and data , contacts...do a full wipe and restore everything but system settings...
or back up you contacts , use pc to back up all movies , music ,pictures , documents you got factory reset copy everything back configure google play so all your app are restore....i like this better
or do as above but instead of factory reset flash with odin

Okay, I just factory reset the device, wiped data, system, cache, dalvaik cache, flashed ROM, the pin is still there.. what the heck?... It is definitely not there on my Nexus 5...

hey guys,
I have just gotten my phone back from repair. It was getting the cracked lCD replaced.
So i went and put my SIM card into the SIM slot then i rebooted my phone, just to see a "No SIM" message which then proceeded to say "Insert SIM card". My wifi and everything is working and i can make emergency calls. I have previously had problems with my EFS folder and a corrupt IMEI but i fixed that issue and i don't believe that these two incidents are related whatsoever.
This is the thread with all of the information of my last problem. http://forum.xda-developers.com/galaxy-s5/help/service-t2898890
To try and solve this new problem, i have done the following:
1. Taken the sim card out and restarted phone and entered the sim card back in numerous times in various different sequences.
2. Done a full factory reset, reflashed a new rom, modem and bootloader.
3. Restored the EFS folder.
4. Tried a different SIM card.
This could be a hardware issue, but i feel as though it is software related, but i am no genius so i am open to any suggestions as to what it may be and how i may be able to fix it. If i am not able to fix it i will just send it back to the phone repairers and see what they can do to resolve the problem, but that would be the last thing i want to do.
thanks for any help.
not to worry. I have now solved the problem and everything is working perfectly.

i was on android 4.4.2 thouchwiz, i then upgraded to android 5, which also meant i had to upgrade the modem, which seemed to fix the problem. I then downgraded back down to android 4.4.2 touchwiz and that solved the problem.
so maybe you could try upgrading your modem or something? let me know if that works.

By modem do you mean radio?
It's an unrooted phone in my case, unfortunately.
the modem is a file or software i guess you could say in which controls the the signal on your phone.
hmmmm, im not sure what you could do then... im guessing you do not plan on rooting either?
