I recently bought a second-hand SGS, supposedly locked to 3. The firmware was from 3 UK, but when I punched in *#7465625# it showed all locks are OFF.
Hot for tasty Froyo, first thing i did was to upgrade from the branded Eclair ROM the phone came with to an unbranded stock Froyo ROM. Kies gave me a hard time so I used ODIN. Then I inserted my SIM and realized I could not make calls or even register on my GSM network. (Had not tried the SIM before, so I don't know if the flash caused this)
I found out that the flash had changed my Product Code to KOR, but I managed to change it using THIS GUIDE. However, the step "rm -rf /efs/nv_data.bin.md5" did not work as it was write/read protected. After reboot, the SIM didn't work so I did the "busybox chown 1001:1001 /efs/nv_data.bin". The procedure changed the Pcode to H3G, which I think is the original code, although I was going for XEE.
IMEI has not changed (*#06# gets same no. as is printed below battery)
I live in Sweden, my present CSC is XEE, Product Code is H3G. Network Control Key is 00000000, could this be related?
I considering doing the Product Code change procedure again and see if I can change it too XEE hoping that will fix it, but I'm not even sure this is related to my problem.
Other than that, I'm running out of ideas. However, I'm new to the SGS scene. I'm reaching out for someone with more experience to give me some new ideas.
I've spent hours and hours at this and I've googled like possessed. If I'm being a noob or have overlooked something, let me know - just tell me what I should do to fix this phone.
Go into Settings > Wireless and Network > Mobile Networks and check that Network Mode reads as auto mode. Then open Access Points Names and check that APNs are listed that suit your carrier.
If all of that checks out, go into an app like SGS Tools and use the secret code to check Band Selection.
Thanks for your reply!
I have inserted APN for data. Though, is this really necessary just for 2G calls and SMS?
When I choose "Select Automatically" in Settings/Wireless and network/Mobile Networks/Network Operators then I sometimes get "Registered on network". Then, when trying to call, I get "Data network not available". Band Selection (from SGS Tools secret codes) show:
= BAND SELECTION =
[1] AUTOMATIC []
[2] WSCDMA BAND []
[3] GSM BAND []
[4] COMBI BANDS []
When I select the network operator manually, I get "Unable to select network. Select automatically".
An alternative Go to Rom Kitchen build a rom with
XWJS8 > Hardcore Kernel >CSC CPW > Modem JPY and whatever else you require that should give all UK main networks .

I got Data Network not available when I was investigating my phone (that is, messing about) and changed my Network Mode. Go to Settings > Wireless and Network > Network Mode and choose GSM/WCDMA Auto mode. If you don't have connection, then try first GSM Only, then WCDMA Only...then back to both.
And yes, you need to have a data network connection to make calls. Not sure why. Must be something to do with billing.
I would hate to be right but are you sure, as you've bought it second hand, that it hasn't been registered as stolen? Do you know any history of the phone?
Product code should be GT-I9000HKDXXX, where XXX should be your CSC which is XEE that makes it: GT-I9000HKDXEE, you should not use H3G at all.
double post...sorry

Thanks, but I would need the Swedish networks. The phone is from UK whereas I live in Sweden and have a Swedish operator (halebop).

Weird, I was sure APN is only required for MMS and Internet, not for calls and SMS. Anyway, I have APN so that's not it.

No, I don't and I can't be 100% sure it's not stolen. However, I have a bill of sale with all his information and I know where he lives so if that's the case, it can be sorted.

I think you are right, and I managed to change it so now both CSC and Product Code reads XEE, which should be correct for Sweden. However, the problem remains the same.
There is a possible solution from HERE, however it seems rather ...old. Having no other ideas I'll try it unless someone comes up with a better idea:
Richthofen said:
Possible problems (I had them all due trying different thing to solve it):
No service.
There is no service even a functional SIM card is inserted.
You cannot receive or make calls, receive or send sms, etc (obviously).
Freeze / lock-down.
The phone will not react to anything besides pressing power key.
You cannot unlock the display to enter PIN code.
Wrong PIN code.
The phone will not accept any PIN code on any SIM (even the correct one ).
Phone displays "wrong PIN code" message even the try counter (three strikes you know) does not change.
Product code changed to KOR.
= Blocked Kies updates (without a registry "hack")
Here is how to fix any or all of them:
Downgrade to I9000XWJM9 firmware with Odin (as usual).
Remove SIM card from the phone (to be able to boot in first place) and start the phone.
Gain root access and install "Root Explorer" (or similar), ADB works too.
Open Root Explorer and go to the "EFS" folder in the root.
Check the date on .nv_data.bak and .nv_data.bak.md5 files.
If it is earlier than 08/26/2010 you´re clear, if it is later then you may stop reading.
Once the date has been checked, select files nv_data.bin and nv_data.bin.md5 simultaneously and delete (yes, delete) them. Reboot the phone.
Now your phone is in the same condition (atleast permanent memory wise) as it was prior I9000XXJPC update.
There is a safety feature I would call "a dead mans switch".
If the current nv_data files are deleted, the phone will make new nv_data files from the .bak (backup) files (if they excist). The new nv_data files will be signed automatically so they pass the checks (none of the errors listed above will occur). However if they do not excist, the phone will just write an empty / test file (= IMEI corrupted, no service, etc). Also if you just rename .bak files they will have wrong signatures and the same problems will occur.
There is no bootloaders included, so it is safe to flash for everyone.

Have you tried doing a factory reset? May not work but may be worth a try.
Could only be either apn related (doubtful), faulty sim or stolen/lost phone. Unless hardware related.

Thanks, it seems a long shot but I will try it tomorrow.
I've already flashed the phone to XWJM9 with correct CSC folllowing the guide in my previous post. Restoring nv_data.bin and nv_data.bin.md5 from the .bak files didn't help, the .bak files were just three days old so the data there might have been contaminated.
As far as I can tell there's either a hardware fault, the phone is stolen, or I've messed up the precious data in /EFS by my first ODIN flash, before I did the back-up. Every guide should have that backup procedure as first step, mine didn't. :'(
I've mailed my operator so hopefully I'll get an answer tomorrow to whether the IMEI is blocked.
"No service" sucks...

I'm leaving the country on Sunday and I need to be able to use my phone with an international SIM. What is the quickest way to international unlock it by then? I see a lot of conflicting information like I can't downgrade from NG2 or something like that. Any help?
Hope This helps.

if you need any help; please pm me, or search this site for answers. I am sure you are not the first person, to want to do this or to have this question.
Before you continue; please note that i am not liable for any damages, that may occur to any the devices you attempt this on.
To undo any and all of the changes that you are about to make to your phone(**NOTE** the following will erase all data on your phone so backup everything you want to keep.), (1) first download an app called MSL utility and write down your MSL code on a computer, or any other device maybe even pen and paper.(2) go to your phone settings hit activate this device when it is done loading do not click done.(3) click on the menu button and go to PST settings. (4) go to the ##SCRTN# menu and follow what it prompts you to do, your phone will then reboot automatically. (5) do steps 2 and 3 over again and go to the ##RTN# menu and follow the prompts your phone should than reboot automatically and now you should see an invalid SIM sign. **NOTE** any time it asks you to enter a code it means enter you MSL code. Remember to undo these steps first. (No. 2)**NOTE** when your done with steps below download BuildProp Editor(you must have root), and click on the pencil icon; scroll to the bottom, and add these two lines: ril.sales_code=LOL ro.csc.sales_code=LOL)
No. 1) = No, you do not need to downgrade.
No. 2)**NOTE** when your done with steps below download BuildProp Editor(you must have root), and click on the pencil icon; scroll to the bottom, and add these two lines:
ril.sales_code=LOL
ro.csc.sales_code=LOL
save and reboot
with sim inside the apn should be set automatically. If not, well than google your apn, and add it manually.
done.
This is a re-post(i would thank whom ever posted this, though i do not recall where i found it.); because i am to lazy, to write it from scratch.
1. Use ssu.apk to unlock it first
2. use cf auto root to it
3 .use adb:
su
am broadcast -a android.provider.Telephony.SECRET_CODE -d android_secret_code://27663368378
UMTS -> DEBUG SCREEN -> PHONE CONTROL -> NETWORK CONTROL -> GCF
There the phone is domestic unlock without downgrading the modem.
1. be on stock NG2. ssu.apk force-closes on aosp/custom roms.
2. Run ssu.apk and do the unlock. This does not require root.
3. do the other commands through ADB(step 3 Above), just in case. You may or may not need them. I don't know why it worked for me without them. That step DOES require root.
4. Test your sim card and make sure your phone can read it, and if possible, make a call, try text/data, whatever.
You're Welcome!
I had NAE i downgrade to mdc then unlocked it and after that i download firmware which is NG2-xas i think and after upgrading its still unlock.
For that method and files you can search international sim unlock.
Its easy to do it.

Thanks so much for the quick response!
Couple of things, I actually called Sprint to ask them to unlock it for international SIMs, and they said they'd go ahead and do it. I flashed back to Stock and did the UICC Unlock thing in the menu like they told me. The phone rebooted. I think it's unlocked then, correct? If not, I'll go ahead and do this method tonight.
Also, does this phone support LTE (Is that the right term) on international GSM networks or just 3g?
Thanks!

it may be unlocked; you would not know for certain unless, you attempt to insert an international sim card.
Depending on which country you are traveling to. Some countries only have 2-G, then there is some that use 3-G, some also utilize HAPA+, and LTE. It also depends on the sim card they give to you. If the give an LTE sim card, it may work (for LTE or HSPA+). Though it depends on which band/frequency, its relying on. click here to see LTE frequency data sheet. click here to select the country you are traveling to, this way you'll know if you will be able to be on a favorable network.

I don't know if that's true. What i do know is that the last time i was in Israel, i used Golan Telecom, and i only had a 3G connection. i do know that they state they have a 4G-Lte network, but i guess i'll have to find out in a few months from now.
good luck.
Let me start off by saying I am a noob with these things. I also have searched a few of these forums and found steps by "cellzealot" on how to edit the NV Decimal settings to allow this phone to work on other carriers. I followed these steps and everything went through without any errors but the same issue is happening when I then try to get the phone to work on T-Mobile network. What happens is (after the above mentioned tutorial) I restart the phone, put my T-Mobile sim card in the phone. The phone then states "This SIM card is from an unknown source". In my settings menu under mobile networks In "preffered network type" I can choose Global, LTE/CDMA, or GSM/UMTS and nothing makes a difference. I dont know if it is in-fact unlocked and working and maybe this phone is malfunctioning or maybe I am just missing a step? Some additional info under settings:
About phone>Status>Network = "Unknown", Network type and strength = "No service", Mobile network state = "disconnected", my phone number = "unknown".
System Version: 183.46.15.XT907.Verizon.en.US
Android Version: 4.4.2
Any help is much appreciated, thanks in advance, you guys are awesome for your work here.
I would like to unlock my x compact phone. When I go to the sim lock page by dialling *#*#7378423#*#* I see the dreaded line "[x] network 0" suggesting that the phone is hard locked (has no unlocking attempts left) - see screenshot below.
However, further down it also says: "Max Attempts: 5", and I am unable to find an explanation whether this means that there are 5 attempts left or not. I cannot find a similar screenshot with someone explaining what the info means, in particular, how it relates to the hardlocking info given in the line with network.
Can someone help? Thanks!
Unfortunately, as a new member I cannot add an outside link, so here's what it says on the sim lock info page:
SIM Card IMSI:
[x] network 0
.
.
.
[ ] SIM 0
Detail SIM lock info:
Version: 2
Configuration:
Max Attempts: 5
Test IMSI: len 9
IMSI: len 7,00101-*
etc.
HELLO,
I was given a Psmart model FIG-lx1c109 (orange) simple-sim. (on the original box only one number imei).
Good
I got the bootloader code.
I installed oeminfo dual-sim FIG-lx1c432.
the device has become fig-lx1c432b176. it shows me sim1 correctly and sim2 00000000000000.
the problem is that only one sim sounds, never both. If I call the other sim live on the answering machine.
all I can do is go to phone settings and switch from one sim to another.
Is this normal?
how can i fix it problem?
thank you
edit because the problem is solved, I appealed to google and he offered me https://ministryofsolutions.com/huawei-bootloader-unlock-paid-service-html.
i installed whatsapp, $ 15 from paypal, teamwiewer and i followed the instructions (do not touch the phone). I will not tell you more because I'm not sure that everything is allowed (in France or elsewhere).
Ps it's really good if you're in trouble. thank you
