since ver 4.0.4 has some issues, would suggest u to rewert back to stock 4.0.3 and then see if the issue persists, if its not there then stay with v4.0.3 untill a stable v4.0.4 is released
ps- do not make any wipes in recovery, or backup ur phone with the same with v4.0.4 since the same can potentially brick ur phone

SIM is not dead. turn out to be a phone issue. not resolved yet but find it very strange how it can go from non-lock to locked with network control key prompt.
used GSII repair from the market, it resolved the issue but now the phone is unable to turn on any security pattern prompt for instance, and it has a weird box logo right on the home screen.
anyone had this problem before?

Yes I've suddenly had this issue, but found the app 'Galaxy_S Unlock' on the market which quickly resolved my phone being locked.
But the problem persists as it randomly locks itself again, and I have to use this app again, bit of a pain as this is a work phone, but luckily it still unlocks with this app.
Looking for a permanent solution, anyone have any ideas what the real issue is here, and yes I'm using v4.o4 firmware on my phone.

My SII just got the OTA update to 4.04 this morning and is now doing the same thing, my carrier is pretty indifferent as its unlocked so I'm trying to get help out of Samsung. Mostly adding my 2c to give the topic a bump

Same trouble here after a flash to Resurrection v3.0.5, prompt of Enter Network Unlock Control Key.
Tried the unlock apps from the market and no go, tried flashing a few other Roms, restored a few nandroid backups, factory resets and still nothing. Put the SIM into my backup phone to test and no problems with that.
Strange when accessing the menu at *#7465625# the network locks were listed as off.
What did work for me was to flash back to the original stock Rom that came with the phone (KG2 Bell). After the reboot there was still no signal so I entered stock recovery and did a factory reset, cleared cache partition/dalvik cache, fix permisions and reboot.
After that all has been working good and was able to flash back to my nandroid backup.

I just packed it off to Samsung, they didn't admit fault but the phone is out of warranty but they are fixing it free of charge. Smells like victory..

[Q] How can I go back to Stock ROM c/w Radio working

Hi Guys, hoping someone can help me here.
I know I have replied to another thread asking the same question, but I wanted to ask in my own post so I could detail exactly what I have done in the hope someone can point out to me what a complete idiot I have been and put me right.
I tried to upgrade my sons phone this week which was on MiniCM7-2.07. I followed all the instructions to unlock bootloader etc and all seemed to go well, I booted up into MiniCM7-2.15 successfully however there is no network coverage, and there hasnt been since. The phone was sim unlocked about a year ago but I cant remember if I got Orange to do it for me or I paid one of the various unlockers for the code. I know it was never hooked up to a separate machine (SETOOL?). I tried my original Orange SIM in it to see if that fixed it, but still no joy.
You are able to browse the various networks available as it searches for them and finds them, but when you choose a certain network it returns with an error that your SIM will not work with that network, or words to that effect.
If you take the SIM out you get a totally different error, so pretty sure the SIM carrier is working.
So, to rectify this I relocked the bootloader and used SEUS to go back to stock 2.1. This all worked fine apart from I still have no network. WIFI works fine, but no data or phone calls.
I have tried flashing other kernels, again with no joy, always the same problem.
What else can I try? I used to do mess around with linux so I know my way around console, is there a module in the kernel I could try swapping or changing? Surely there is something that is controlling that part of the phone that has been changed and isnt being changed back again? What does SEUS do, does it just restore the ROM or is it the kernel too?
Really hoping someone can help with this, as of this moment the x10mini is as good as a chocolate tea pot to me

Did you find a decision of your problem? I have the same problem, with the only difference that I never changed the ROM. I just rooted the phone with the SuperOneClick tool, and then tried to unlock the bootloader, but with no luck there. After completing all the steps in the tutorial with no problems during the process, it remained locked.
And I just realized after that, that the phone has the sim card problem, just as yours.
So any suggestions?
guys first of all let's try a test if you have an unlocked bootloader go ahead and flash the latest nAa Kernel (nAa-10) then from that kernel install MiniCM7 2.1.8 and tell me your results if it was negative you should reflash all Without locking the bootloader from SEUS via the Repair option therefore after this it should work as the SEUS restore all the software kernel and ROM to its original state from the manufacturer Sony Ericsson.
let me know what will happen with you.
Any feedback on this?
Thanks!

[Q] [HELP] My E10i won't recognize the SIM card, and i have no signal!!!

Hi guys, I need your help badly, plzzzz.
So, it happened one day that my phone kept restarting after I wanted to call my mum. Every time the phone booted up, and i typed in the right PIN, the problem remaind.
I tought that a factory reset could solve the problem...it couldn't. (btw, without the SIM in it, the phone worked; thats how i menaged to do a factory reset). After that i managed to upgrade the firmware (from 2.1.1.A.0.6 to 2.1.1.C.0.0) even though that PCC said that there is no upgrade for my phone. Finally I solved the problem, but just for i while. Everything was good till i dialed again, the problem reappeared.This time it didn't recognise the SIM anymore and i had no signal, but the restarting stoped.
Then i tried something else. I wanted to unlock the bootloader, but it was already unlocked (i bought the phone secondhand), so I replaced the stock kernel and the rom, with nAa kernel(v.13) and a MiniCM7-2.2.1 custom rom. But the problem still remains. The current state is that i keep recieving "Insert the SIM card, and restart the phone" notification, and i have no signal, everything else is work fine. Plz give me suggestions what to do, to restore the cell to usable state. Thank you for advance for you'r assistance.

Repair to stock rom and lock your bootloader might do the trick.. don't lock the bootloader on a custom kernel.

[Q] Unlocked phone connects to phone network under stock ROM but not custom ROMs

I had my S2 unlocked via software while I was abroad to use the local SIM card - the person who did it couldn't unlock it, first blaming the phone as rooted and then hardware as damaged. Instead they made it worse, the phone doesn't connect to any network, whatever SIM card I use. At the time I was using a rooted custom ROM (Rootbox) v4.2.
I found if I use a stock ROM, even if rooted, it connects to phone networks and is unlocked to any SIM card. As you may know, the S2 can only upgrade to v4.1.2 if stock.
I have been going around in circles trying different kernels and ROMs. I would rather use v4.2 than stick with v4.1.2... Rootbox v4.2 used to work fine before trying to unlock the phone.
I have used the 'GalaxSim Unlock' app, in case the unlock process was only partial. I also tried to find if I could relock the phone back to the original network, by removing the EFS folder.
Does anyone know why this is happening? Thank you in advance.
Phone was originally SIM locked to T-Mobile.
Does anyone have an idea why this is happening?
Or has had it happen to them in the past?
The IMEI number is still intact.

Any fix?? No Sim Network Signal on Xperia SOLA

Hello everyone! I hope somebody can help me with my problem on my SOLA. As stated on the title on top I lost my Sim network Signal. The icon on top of the screen has been grayed out. It started when my SOLA was running a custom ROM SlimKat by alwaysadeel. I am not blaming the veloper but it goes like this, while the sola was on SlimKat I had this Advanced task killer pro installed on the phone. In the app, there is this FIX button at the buttom of the screen so hit it and then I started losing the Sim signal. I tired to hit that FIX button but nothing happened. Then I switch back to Stock ICS but the problem with sim signal is still there. Then I am seeing this "SIM not provisioned MM # 2 error" SIM that I tried to used during this issue are working/operational on other phones so I am definite that it is the device itself ha the problem and not the simcards. I even relocked my bootloader and tried fixing wigth PCC but I am so clueless how to fix it with PCC. If anybody has solution to this problem please I need your help. Thanks a lot.
Well, this is strange, you should be able to see signal after switching to stock ROM.
Assuming its a s/w fault.
anyways, first, the error means either sim card is corrupted or it hasn't been activated yet. Both are not possible in your case as we n=know they are working on other sets.
I suppose you are seeing this error AFTER switching to stock ICS, right ?
now, possible troubleshooting :
first, try CM, or again install SlimKat. After this you can try different kernels too.
second, check your ics release, it should be of your region, MT27a or MT27i, version should be right.
after downloading correct version, flash using flashtool, wipe everything.
hope it helps, as the problem is unique, i cannot think of any other possible solution.

I have a similar problem in a Xperia U, I've flash a CM9 rom like a month ago, and was working incredible, smooth, fast, everything ok, till this monday when lost signal, works ok with wifi, and also with data (at least in whatsapp, no fb, or youtube) but I can´t send sms or make a call, I've tried to flash stock (ICS) but the problem is there, even flashing just the baseband and the complete firmware with flashtool, I'll tried with GB now, but don´t know what else to do, when power on, recognize the carrier (for one or two seconds) then loose it, and when you search for networks, it say (Error al buscar redes) that an error ocurred, if you find a solution please share it, or if anyone have any suggestions, they are welcome... Thanks!!
PS. Can you believe it!?!?!?! MY own company have mi IMEI denied, I use a provisory sim card, FROM the carrier for a few days, while they changed my real number and gime my new sim card, to be able to change of company (carrier), then, a couple of months later, they discharged that "disposal" line and my IMEI went down with it, now I have to go to the office and solve the problem that they create me. Sorry, I know is offtopic, but I want to share in case someone else have this issue.

gt-i9300 imei correct, but sim is locked

Hi,
the problem is:
I have a galaxy s3 (i9300) which i'm not able to unlock. The *#06# shows the correct IMEI, which is printed on the label behind the battery.
I've tried editing nv_data.bin, but can't seem to find the 00181460 address.
Galaxsim says "unable to load nv data"
The problems started about a month after i upgraded to 4.4.4 (back to n00t rom). One morning the phone just kept saysing 'unfortunately com.android.phone has stopped working'
I tried reflashing it, then tried using cm13.
Everything works fine, except there's now a sim lock on my phone..
running out of ideas, so thought maybe you guys have some fresh ones.
Thanks!
The standard repair-procedure is to flash firmware by Odin.
hello, i have the same problem. i tried lot of rom to solve the problem but it don't do anything. Also flashing firmware by Odin don't work. I'm happy that i'm not alone.
sorry for my bad english.
Hello, have you ever tried to flash the stock firmware with Odin ? For me, it did not solve the problem. If someone has a solution. ..:crying:
The phone is network locked or is the SIM card locked with a pin?

hi, the phone is network locked.
The only method that may work to unlock the phone for free is the regionlockaway app with root and an older modem.
Was the phone ever network unlocked ?
Thanks for your answer .
Yes, the phone was network unlocked when i bought it.
i tried regionlockaway, but it don't work.
I don't know what to do.
Not sure why the phone would relock. You tried installing a stock rom?
I tried this too, but it don't worked.
I tried to change The modem, the CSC, but nothing happens, the phone remains network locked.
Did you check to make sure the phone was network unlocked when you first got it?
Yes, it was unlocked.
no network after custom rom 4.4.4
Hi all!
I also have the same problem after a cutom Rom install, >no Network, Hope you be of help as i expect XDA always do :angel:
No network is not the same as bein network locked.
If the phone can't be unlocked for free, an unlock code must be purchased.

My Gt-i9300 shows my sim as it is LycaMobile but also gives me 'Emergency calls only; so i cant call and etc... is there a way to restore it to full stock firmware ? because i also flashed baseband modem etcetera , and ididnt change to Gsm only ( i read somewhere that be a solution...?
Changing to gsm only will only give the phone data access at edge speeds.
To return to stock, flash a rom from sammobile.com using Odin.
I bought an unlocked phone to change operator when i want and i still have to pay ? Oh misery... :'(

Did you confirm the phone was network unlocked when you first got it? The phone supports your carrier's radio frequencies? SIM card works in another phone?
You can use turbosim for unlock but i dont know what happen to you. Its only suggestion.
You can't network unlock an s3 for free if it has ever been updated to 4.3.
