Have you tried sgs unlocker?

Yes, I unlocked my Phone on Android 2.1 EClair and it is still unlocked on 2.2.1 JPU. These are not iPhones, therefore they do not require a hack.. Hell samsung stores the unlock code on your phone!

SGS Unlocker says to me:
"Sorry no codes found
File not found: Do you have a Samsung Galaxy S?"

I think you need to have root for the unlock to work in Froyo. If possible dowgrade to Eclair, unlock and upgrade back to Froyo ... or get root in Froyo first.

Its probably unlocked, have you tried another sim on it yet?

In settings, there is Location & Security, & you find Set up SIM card lock. HAVE YOU DONE THAT? Verify.

When you put in another SIM, is it asking for a PIN to use phone?

sorry for my bad english.
I put in my other sim card and first it asks me for a pin. So I enter the pin and the it asks me for a "network- unlock code" (i think that's what it's called in english).

Is this a used phone you bought?

I think the original owner put a SIM lock code on it. Worst case, you bought a stolen phone.

If you can put the phone to download mode, why dont you try flashing a 2.1 ROM? See if it works.

I bought this phone with a contract from "3"-Austria. I'm the first owner.
So now I want to go to Poland to visit my family and put in another sim card.
The usual Pin it asks me I enter sucessfully and then it pops up this messege:
"Siim network unlock Pin".......
-->I think this is the code I need.
When i enter *#7465625#
it says: --> Network Lock [ON]

Try this thread, & ask the developer if he can help you.

you should try what i suggested. the link i posted comes from the the app sgs unlock. try pressing the menu on sgs unlock app and choose generate NV_Data.bin it will lead you to the link i posted earlier.
the tutorial will replace the files that locks your phone. thats why you should make a back up on your /efs folder for warranty or emergency concern.
tried it successfully with 2.2

Do you know if this could work also on gingerbread 2.3.5?

New JL2 Bell i9000M not unlockable?

Hey guys. So I finally got my SGS back from Bell again (This is my 2nd replacement). Right away I got to work to unlock it. However, it seems that Bell has changed how unlocking works again. I recall when I got my first replacement, I could not unlock it. I could get the network control key (aka the "unlock code") using the SGS Unlock apk, but the phone would not accept this as a valid code. Instead, I was able to relock the phone to my carrier by changing the MCC/MNC code, and then entering the network control key. This worked perfectly.
This method does not to seem to work on my new replacement, however. Using the SGS Unlock and the generate unlock script, both can not seem to find the nv_data.bin file. As a result, I do not get an unlock code of any sort.
I've also attempted to downgrade my phone, but flashing JH2 with Odin puts my phone in a boot loop. Should I try another 2.1 ROM?
In the worst case, is it possible that Bell has been replacing phones with totally non-unlockable phones?
I'm at my wit's end as to what to try next. Any suggestions?

Greetings...Assuming you have rooted your phone, use SGS unlock from the market and you will need to install busy box as well.
That's what I used for my JL2 build and it worked.

Is busy box absolutely necessary? I had installed Darky's rom, so I had root+super user, but I'm not sure if I had busy box.
I had also tried to use the app to generate root codes, but it gave me the same error; no code found.

Rooted my phone and have busybox installed (I forgot that SuperUser = busy box).
Tried the apps from the market, didn't work.
When did you get your phone? Did you buy it new from Bell or was it a replacement?
edit: OKAY FORGET EVERYTHING I SAID
I figured it out.
This what I did:
1) http://forum.xda-developers.com/showthread.php?t=803682
I used this application to root my phone.
2) Restarted my phone (I tried to unlock without restarting, it didn't work.)
3) http://www.androlib.com/android.application.com-helroz-galaxysunlock-zxpBC.aspx
I then used this application to unlock. Remember to back up your EFS before doing anything.
4) I entered *#7465625# on the phone to verify the unlock.
I hope this helps anyone else who had the same problem as me.
Thanks a lot guys!

Codes often don't work on the new i9000m revisions. Use the nv_data hexedit method, changing 01 to 00, as can be found elsewhere in the forums.
Read around, your solution is out there already.
Best to do these things manually instead of with an automatic tool imo - only takes a few minutes longer, and then you'll actually understand the process.

Galaxy S GT-I9000 unlock help please

I found this great forum a few days ago and after a lot of reading I have managed to root the phone and install a few apps.
I have also been able to backup my efs folder and edit the nv_data.bin file using a hex editor as per this thread here http://forum.xda-developers.com/showthread.php?t=761045.
However after changing the byte 01 to 00 at line 0018146 8 and reloading the file to my phone, it is still asking me for an unlock code
when I put a new sim card in. I have the Galaxy S running GingerBread 2.3.6, Baseband I9000 XXJW4. I have also tried the unlocker softwares posted elsewhere on the forum with no success. Is it possible that anyone can give me pointers on how to successfully unlock the phone please or suggest where I may be going wrong.

i don´t know, if i unterstood you right, but last year i got a new sim card, which is locked by a code by the provider (of course they told me this code). Every time i restart my phone (unless it´s in airplane mode) i have to tipe this code. So maybe in your case it is also the sim card, which is locken and not the phone..

Thanks for the quick reply, but it can't be the sim as it's on Pay As You Go in the U.K and so not a contract sim.

Did you try with Samsung Galaxy S Unlock Tool or SGS Unlock PRO?, it's on the play store i unlook mi phone with it.

Hi,
If i'm understanding you right you are asked for unlock code in the phone startup,
If that is the case i once experience the same problem with my phone and i fix it by typing the wrong codes some times untill the possible retryes are over after that my phone continue to load the OS and after that i never met the problem.
Regards,

Normal USIM unlock code is 0000, if failed you can try the unlock tools on MY android collections link below

Once again thanks for all the replies.
I have tried the 0000 code which failed with a message that network unlock was unsuccessful. I haven't tried any other code because of the 3 strikes and phone barred conditions.

I have also tried the 'Generate Windows Unlock' tool but it seems that the graphics card in both my laptop and desktop is not compatible with the software. I have also tried the SGS Unlock tool as well as the free one from Helroz but failed to unlock the phone. The tool from Helroz successfully changed the relevant bytes according to the software, but when I rebooted the phone it was stuck on the Samsung Galaxy S start screen so I had to re-flash the software and restore the backup of my efs folder.
I have not tried the paid for tool from the market as, being a 68yr old complete newbie to the smart phone era and not yet having a wireless router, I am unsure as to how to get it. To give you some idea of the leap I have made with this phone, which was given to me by my son who has now emigrated to Australia, my current phone is an old Nokia 5110 which I have used for around 12 years.
Thanks for your help and patience.

I have now managed to unlock the phone using SGS Unlock Pro with the generic unlock option, for some reason the Samsung unlock option kept crashing. Thanks for the tip with the Pro version of the software and it seems that I have a lot to learn regarding this phone, now for a different ringtone.:good:

[Q] Unable to unlock phone

So, basically, I got a new pay-as-you-go SIM and I don't want to buy a new phone for it. I was looking for methods to unlock my current galaxy ace, it's rooted and I have a custom ROM on it- The Ultimatum by The "A" Factor. I got my unlock codes and put the SIM in expecting to get a screen saying phone is locked, please put in unlock code or something similar that usually happens. However nothing came up but when the phone finished booting, I had no service and can't use it for calls or anything which suggests that the phone is still locked, I tried using the *#7465525# service code, but I got an error saying no service or incorrect MUDI code or something like that. Is it possible that flashing a new ROM wiped the unlocking procedures and is there anyway for me to know if my phone is unlocked and if not, can I still unlock it?

Didn't show you nothing to introduce the code?¿
... try introducing another SIM from other carrier... when you boot then automatically should ask you to introduce the unlock code
If it doesn't work you could phone to the device's carrier, the carrier must help you if you finished your contract

I do have another SIM from another carrier, but the screen isn't showing up, I've been scouring the internet and found http://forum.xda-developers.com/showthread.php?t=1335548 , turns out it won't show because of my ROM, so I'll have to switch to stock like you said, before I do that though I'll try that code he said at the end to see if it will unlock. Thanks :good:

ok! be carefull with this stuff, you could brick your device if you do something wrong, if I were you I'd phone my carrier to avoid any kind of trouble (if I'd had my contract finished)

[Q] No calling, no texting, everything else works

Hi everyone!
I bought recently a new galaxy s advanced and for some weird reason i can't make calls, can't text and can't receive anything. But i can unlock my sim without any problem and i can use mobile internet.
I had first the original gingerbread rom (i9070XXLK2), rupgraded it to 4.1.2 jelly bean(i9070XXLQE), rooted it, upgraded the kernel to this one: http://forum.xda-developers.com/showthread.php?t=2140597 and after that tried a cyanogen rom(this one => http://forum.xda-developers.com/showthread.php?t=2497660 ), went after the cyanogen back to the 4.1.2 but nothing works.
atm it is running original 4.1.2 rooted and cwm.
I also tried galaxSim but it doesn't support the galaxy s advanced, also the *#simlock# thing does not work. I am not sure there is a simlock on the phone because mobile internet works.
If you need more info just ask! Not really sure what information you need to know.
I have no idea what to do now, i hope some1 can help me.

You must do Factory reset when you change ROM. Do it now.
Do you have I9070 or I9070P? On CM you do not have network unless you change tee folder if your phone is I9070P.

I have factory resetted it 3 or 4 times (after every rom flash).
It's an I9070, not the P one.
If some1 tries to call me they hear an automated message tape thing that says my number is blocked and i need to call my provider.
I did call my provider and there is nothing blocking my number or the phone.
When i put my sim in another phone everything works fine so the issue must be in the phone itself.
Thanks for trying to help :highfive:

I tried 3 different SIM's but all from the same provider, i am going to visit a friend tomorrow to lend his SIM (he has another provider). I wiped dalvik cache every time i factory resetted it (after every rom flash)
Is it possible there is a piece of hardware in the phone blocking the calls and the messages?
Found out something new, if i do phone (the app) => call settings => additional settings, i get a message saying "network or sim card error".
I am searching for an hour now for a fix but i can't find anything. I will keep searching for another couple of hours, i really want to fix this.

I don't know, as far i can see there is no sign of a provider/region lock. During boot no logo from a provider, sim can be unlocked when it asks for my PIN.
I tried to figure out if there is a simlock with *#SIMLOCK# but the code does not work. Any idea how i can see if there is a sim-lock?

I bought it from an auction, a phone shop went bust and they sold thousands of phones. They had over 20 shops and they were not promoting a provider.
it was brand new in a sealed box and as far as i know i don't have warranty.
Is there a place to check if there is still a warranty on the phone?
EDIT: just checked and i have still warranry (produced at oktober 2012) but the problem i have now is, i flashed it a couple of times, isn't my warranty ruined now?

I am not sure how is it in your country about that. You can go to some service center to see if the phone is locked to some carrier.

I just tried to check the binary counter, but as far as i can see it didn't move during the flashes and looks original
When i go in download mode i get this:
Odin mode
Product name: GT-I9070
Custom binary download: no
current binary: samsung official
I think this means it got still warranty?
If it is, i'm going to put back jelly bean on it and try to send it back to samsung, is there a chance they will fix it and won't find out i messed with it?

Yes, just go back to JB and you are good to go. And you can uninstall app that need root if you have any.

No root stuff on the phone anymore, eveything looks how it's suppose to i think

i hope they fix it! Again thanks for the help! :highfive:

Sad news, the phone is back from RMA and there is a simlock on it, but the problem is i can't find a method to remove it 4 free (don't want to pay even more for the damn thing). I am going to a shop from the original carrier over a couple of days(i know which carrier simlocked the crap out of it and they have shops not really far from here) but i am not sure they unlock it for free, and tbh the people that work there probably have no clue how to do it, so i don't have a lot of hope for that so i want to try it first myself if that's possible, but i tried already a couple of things and none of them works. Anyone an idea how i can remove it?

I was afraid of that, thanks to confirm. Went to the carrier which locked the phone and they said it is illegal to unlock it, which isn't true of course (checked it everywhere and it is legal) I will find a way to fix it with the carrier, thanks for the help.
