No service after unlock - Galaxy S II Q&A, Help & Troubleshooting

Hi Guys,
Just tried unlocking my galaxy s2 and everything seemed to work. The chainfire method didnt work so i tried the other method by helroz.
Anyway i tried a new sim and i keep getting no service. My imei number is still the same and has not been affected.
Can anyone help with this problem?
Thank You

Flash a stock firmware again and see what happens.

Hi thanks,
I went completely back to stock and tried a t-mobile (uk) sim and after going through manual network selection I have got that to work.
The only problem is that I am not on t-mobile but im on the three network. I tried a three sim and the phone loads up but again no signal.
When i bought the phone it was meant to be locked but when i put the three sim in it does not ask for an unlock code?

Did you make a backup of your efs folder? If you did, restore it.

yes i did make a backup of the efs folder and have tried restoring it but i still dont get the sim unlock pop up screen on startup
is there a way to manually restore the efs folder because when i went back to stock i lost root?

I don't know how to, so I don't want to give you bad info. I just did a quick search for you (type efs restore manual in search) and found a few threads for other devices. You can ask if they will work with your device.. Sorry I'm not more help. Good luck though

Flash a stock firmware with root permission.see the dev section.
Or just flash a custom roms and try helroz tool.
Lastly.use Galaxsim unlock tool found on playstore.it perfectly work for my docomo s2 (sc-02c).
Sent from my GT-I9100 using xda premium

Just tried the above. The galaxsim unlock tool said my phone was already unlocked but not other network is working on my phone. When i put a non t-mobile sim in my phone it just says emergency calls only. I dont even get a pop up asking for a sim unlock code. Also when i try the code *#7465625# nothing shows up so i cant check if the phone is locked.
please help if anyone has a similar problem

First thing first, was it working before? Where did you buy it from. Carriers have start blocking phones that are reported stolen or have balance in the account.
What does it say in settings/about phone/status?
Does that number match the one on the back of the phone under the battery?
Could you please explain what you did to get to this point?
Flashed bad modem?
Deleted /efs folder or contents?
Remote unlock error?

It was working before and its not a carrier block as it does not recognize the sim at all to begin with....

I am not too sure.. i got the phone from a friend who has messed it up...
He said he flashed the bell upgrade from Gb to ICS and this happened.....
I doubt it .... anyhow... couple of other things
the function *#06# shows a null/nunll
*#9090# - shows nothing
*#2263# - shows nothing in service menu
Also, *2767*3855# system format doesnt work either....
Rom is working fine... wireless and internet are all functional....
If i go to adb... i can see the efs folder and other partitions...
Well yeah, the efs folder will be there, is just generated a new one, with a generic imei.
As i said earlier, mobiletechvidoes can fix it, but since everything is working perfectly, and you live in Canada, might wanna just not worry about it?
I read the ota Canada ics update had a bad install script. Just get the zip file and flash that.
too late for that, the "damage" has been done, and he is already running it, flashing the zip won't help now.

So any way i can revive the phone back to life?
Had this happen to me a few times on my sgs1.
Only thing that fixed it was flashing older stock rom through Odin. You can try samfirmware to get it or there is a complete set of stock files here in the forum as well.
Good luck.

I suggest that you Private Message the user.
I'm sure he will provide the answer ...
And I hope he posts here as well, as it would help others like yourself ....g
I'm not sure if this would help at all but it might be worth a shot.It creates TEST IMEI's and other stuff through ADB .Maybe it can even retrieve your actual IMEI somehow? Post back in this thread if anything comes of it so other people with problems can follow .

Here's my fix
I had the same problem with IMEI showing null/null....this happened after I flashed new radio band to get 4g on Tmobile for my AT&T Galaxy note. It appears that I had flashed a zip file for new radio that messes up the IMEI number. I have heard that others have just simply re-flashed their Note using other custom roms that has it's own radio band and IMEI number reappears. I simply used Samsung Kies to force most current factory rom into my Note (search how to do that) and it added factory setting to my Note...including all the AT&T stuff but it did unroot my phone....but it fixed the problem and I got my IMEI back....PM me if you have any questions.
To get to download mode when hooked up to Kies: hold down volume down and power at the same time until download mode comes up. And push volume up button once download screen comes up. Hook the phone up to Samsung Kies and click "Tools" and click "Firmware upgrade and initialization".....enter model using caps "SGH-I717" and enter ok....and enter serial number...using caps....and sit tight and wait...

[Q] Not registered on network

Hello I have a big problem, after I installed a new and updated ROM my phone won't work on any carrier, so here's what happened:
1.I had the ROM FoxHound_Sniper_Wolf_LPD_ICS_GSII_By_SnakeS and it worked great until the GPS started failing so I decided it was time for a change (until now the phone was working flawlessly with carriers and such)
2.I first tried to install the ROM ParanoidAndroid 3+ ROM Galaxy S2 but I forgot to do a wipe first and then I wiped the phone and re-installed the ROM and it still didn't work.
3.I installed WanamLite Clean & Fast JB 4.1.2 v14.3 without errors until I tried to turn on data networking (I had my APN setup by then) and it didn't turn on so I tried calling and this would pop up:"Not registered on network".
4.I try to fix the problem by going to network providers and selecting my network provider and it said: "Unable to connect, try later", so I try selecting the automatic setting and it gave me the same error, so I kept pressing the select automatically setting until it said: "Registered on network" so I try to call again and still gives me the same error "Not registered on network".
5.I try to go back to my old ROM (FoxHound_Sniper_Wolf_LPD_ICS_GSII_By_SnakeS) and it still gave me the error "Not registered on network".
6.I also tried some other ROMs: RR_JB_V3.1.3_AOKP_4.2.1_I9100 and RootBox-JB-i9100-V4.1 and the phone still won't work.
7.I go back to the WanamLite Clean & Fast JB 4.1.2 but this time it's v14.6
PS:it says "emergency calls only" in the drop down menu
info:
county: Israel
carrier: Golan Telecom
phone status: I got it unlocked from the company Cellcom
Network mode: GSM/CDMA (Auto mode)
ROM: WanamLite Clean & Fast JB 4.1.2
Galaxy sII GT-1900T
SSN:-I900TGSMH
Can anyone help me with this please?

Hey man I tried this fix: http://forum.xda-developers.com/showthread.php?p=17587351
and when I did step 3 it was fixed but now I have the generic imei (004999010640000)
all you had to do was checking your IMEI online to see if it was blocked listed.
You now ended up with a generic IMEI.
You followed the first 3 steps right?
Please tell me you backed up the EFS folder.

Restore imei on shw-250S/K

HI guys, I bought SHW-250S from Korea.
flashed it with 4.1.2 rom following this post: http://forum.xda-developers.com/showthread.php?t=1595225
with success , with few issues
then it turned out some of the simcards are not accepted. Funny part is one simcard from say Orange will work, other Orange simcard wont .
Further investigation lead me to conclusion that nv_data.bin / efs folder is corrupted and IMEI is wrong and changed to generic... so i tried to restore IMEI following this post : http://forum.xda-developers.com/showthread.php?t=881162
unfortunately that didnt help on shw-250S ,
Does anyone know solution specific for shw-250S? Does anyone have enough skills to hack these hexes and fix IMEI on shw-250S or K models? I can pay

Do you have a working Bk up of your efs? Bk it up if it works on one Sim use ktool of playstore to Bk it up when working then put in bad Sim in then restore. If it don't work after that its Sim problem. Your phone is unlocked to any network?
Use root browser of playstore as its free

thanks adrewwright for working on this with me
Ill test that later but the problem remains - with some sims these s2 work , with some dont. And IMEI is corrupted. If that was just single network that wasnt working, or even few, then i could sell it as "Orange" . but thats not the case because its unreliable and might get returned regardless of network. You understand the problem?
Some networks block imei from working and some don't if its bin reported as stolen or not paid bill. Is it blocked? Ring your network and ask this question. But you say its the same network just different Sim card.? Not sure Atm best bet ring network and see then we will know for sure.

Check if there is a difference with modems first mate. To be safe. Also have you bked up your working efs folder many time also to be safe. :thumbup: I would leave ril out and see, if no difference then flash modem/ril combo

Did you try to Bk up efs on good Sim card signal then restore it when its gone bad? If you have a good efs save it with ktool then go to bad Sim card and restore it.

If you've tried everything else, I suggest you take it to Service Centre near you. Looks like that fall is to be blamed.
P.S. Please post device related issues in their specific forums. That way you will get faster and better answers! :good:

i tried that link but unfortunately it didnt work may be is because i didnt have backup of esf files i missed some of the files like .nv_data i only have nv_data.bak,
So, your SIM card lost contact when the phone hit the floor and then instead of trying to remove the SIM card and put it back in you went and flashed the phone to solve the problem and that resulted in loosing IMEI number?
The Custom Rom you installed didn't make backup of your EFS folder?

yes exactly when the phone hit the floor and then instead of trying to remove the SIM card and put it back in i went and flashed the phone to solve the problem and that resulted in loosing IMEI number, but before i flashed it i made a backup of my rom using twrp but after this crash i restore my rom using the same twrp but my phone hang on booting,i was using ApoloJb_4.8_Extremev2_twrp kernel
the phone is acting very strength now,i found out even when i installed stock rom, my files are still on the phone,i used odin flashed it,please can any one provide link for me on how to fresh install stock rom and clear everything on the phone
How to install stock rom ? Search. This has been covered here thousands of times over the past two years, I'm not about to regurgitate it because you can't be bothered searching. Get a stock rom for your carrier/country from Samfirmware, then read the guides/tutorials stickied near the top of the General section.
If you want this fixed it's going to take a bit off effort on your part, we can't do everything for you.
Have you
1) Try another SIM card?
2) Look at the mobile network setting? Look for any abnormal setting? can search the mobile provider etc?
3) Try to flash another modem driver?

Hi, to add on, maybe you should tried again flashing with different modem/radio. The different ROM that you flashed may be using the same modem/radio and they may not work on your phone.

This link seems to have mentioned various modem/radio for S2. You may want to try it. You may want to refer to another working S2 and check out what is the working modem/radio working well in your area. Then you flash in the same radio/modem.
If this still does work, it may be really the dropping of your phone has kill some physical part of your phone?

still don't work? strange!
just now i experienced the similar issue like yours, no signal bar. this happen after my phone become no respond to any key press. i have to hard power up through long press. when it power up i then see that there is no signal.
so i quickly go to recovery and flash a Modem/radio that i downloaded earlier.
after flash and it booted with good signal.
but my cause of issue i believe is kernel related as i just flash a dorimanx kernel yesterday.

[Q] Phone not unlocking

So I have gone from stock 4.2.2 to stock 4.1.2 flashing with Odin. Got stuck in a boot loop so had to go to android recovery and factory reset. Then I tried using titanium backup to restore my apps but that didn't work fully and it got stuck in a boot loop on the reboot. Factory reset again and seems to be working fine now. Phone is rooted using Kingo Android Root and used Titanium Backup again for just one app and it worked fine.
Installed BusyBox and GalaxSim Unlock to unlock the phone and an error message saying that it's unable to read nv data shows up. Restored an efs backup and that did nothing. Also tried using the 8#197 code to no avail. Got that the menu didn't exist and command is 186 after a few clicks.
Any advice? Flash it again?

Sim unlock. Most of that was just background info. GalaxSim Unlock gives me an "Unable to read NV data" message. So the sim card isn't being read. Just gives me emergency calls.

Hi,
I suppose your rom is too recent (baseband MG4 or higher). Samsung changed the EFS format on recent roms. As of now, GalaxSim Unlock is not able to read it. I'm working on it.

I see. Already sent it to phone repair to see what can be done. If that doesn't work I guess I'll go back to Ice Cream Sandwich and see if it can be read then.
Needed some rewriting of info in the phone but fixed for the most past anyway. Oh well.
