I got an unlock code for Galaxy S3 from TMO. I enter it and it didn't work. It said "network unlock request unsuccessful". I tried it for a couple times, wifi on, different carriers, the code still no good. Called TMO again and they said the code is correct verifying the IMEI. Anyone experience this? (It's on CM 10.2).
They also said my phone most likely permanently LOCKED the sim carrier!!! I was like WTF. I don't even know there's such thing. How is it possible the sim carrier being permanently locked.Now I'm stuck cuz they can only generate one code per IMEI (according to the rep). If I buy an unlock code online, will it work?
If you do too many unsuccessful attempts to unlock the sim then it can permanently lock it.. And did you try it with CM? With the s3 it would only work with touchwiz, try it with that

In the GENERAL section for our T999 there is a thread by "mrgodai" named "Sim Unlock".. I just did it last night and it worked. You WILL have to downgrade to 4.1.1 (I used the root66 4.1.1) via ODIN.. Then you follow the OPs instructions, then once it shows SUCCESSFUL you can go back to your backed up nandroid to whatever ROM.. I'm using CM11 4.4.2

I have got at&t unlocked phone and I haven't had any problem from above an year but I have been having signal problems from two weeks now. Messages come and go after hours, sometimes they are quick. It's like my phone is on it's own mood whether to send or not. When I try to check credits I get the error "Connection problem or inavlid MMI code". Sometimes my phone's carrier disappear too. Signals are all full. I tried porting into another carrier and found no difference at all.
I think it's related to IMEI because when I *#06# then a pop comes written "0" on it instead of showing IMEI code. Please help! Thanks!
For some reason, it looks like the folder containing your IMEI has been corrupted. Try to re-install the imei using NV writer.

Have you recently updated your rom or flashed anything? Maybe you could flash the modem files again and fix your problem?
When you go to about phone what does it say for baseband?

I think the problem occurred after I flashed leaked version of stock 4.3. Firmware was I747UCUEMJ2. I flashed CyanogenMod 10.2 hoping that it might fix the problem but it didn't made any difference.
I checked baseband version and surprisingly, it's I747UCUEMJ2. So, what do you think? Is that the problem? Also, how can I fix this? Last question, what if I restore IMEI etc then will it still be unlocked or I will need an at&t sim?

Restoring will not re-lock the phone. If your imei and baseband appear correct, I don't think you need to inject the imei.
You could use Odin to flash back to stock and see if the problem persists.

So the imei from the phone's keypad matches the imei on the phone's label?
Yes, it does.

And I still can't check how many credits I have. When I dial *124# then it's saying "Connection problem or invalid MMI code".

Sorry to disturb but I have a question. Since carriers over here doesn't provide micro-sim so we have to cut out large sims and then ready to use. So, I did that but I also noticed that my friend who has S3 got smaller sim circuit and my sim's circuit covers almost whole sim. Maybe that could be the problem? Please answer so I can then contact carrier.

I was running the official Samsung ROM with CF auto root. I made an EFS backup (Using EFS backup Pro) soon after completing the root.
A few days later I tried to flash the modem on my phone to enable AWS bands. After the process my phone got stock on the logo screen.
Then I downloaded the stock ROM + modem from samsmobile and restored it using Odin. The phone boots fine but has a null IMEI and baseband version. I tried restoring EFS using EFS backup pro and the dd command but no luck.
Then I tried the DN3 rom. My phone works perfectly. It boots fine, the network works fine, IMEI is correct!
The problem now is that I cannot unlock my phone. I have tried ordering an unlock code from 2 different websites. Both of them gave the same code. When I insert a different SIM and enter the unlock code I get a message "network unlock unsuccessful". The support team for one of the unlock sites told me enter the code from the UTMS debug menu. The problem is that this menu is not accessible in the DN3 rom. The other company (Koodo) refused to unlock unless I was on the offical ROM.
I tried opening nv_data.bin stored in the EFS parition and it is all 1's. Hence, My suspicion is that DN3 reads the EFS data from a different partition than the offical ROM (dev/block/mmcblk0p3 .
You could help me in 2 ways : Show me how to unlock my phone in DN3 rom. Help me get the offical ROM from samsmobile working.
Thanks in advance to anyone who responds.

So this is a koodo phone, correct? And you had previously unlocked via the service menu?
No Its not a Koodo phone, it is a rogers phone. It has never been unlocked before. Koodo can unlock phones locked to other carriers as well. I took it to them because they were offering free unlock service for new customers. The agent at the kiosk could not find the UTMS menu so he said he could not proceed with the unlock.
I have also tried getting the unlock code by paying a website $20. I tried entering the code but the unlock was unsuccessful. Their support team said that they can only support people using stock ROM and refunded my money.

If the phone was properly unlocked in the first instance, it would be impossible to lock it back again as the unlocking process should survive any firmware upgrade. I'm somewhat puzzled by your question. Could you please clarify? The only way to test if it is still locked would be to put a non-standard SIM inside (i.e. any non AT&T sim). If it requests an unlock code, then it means it was not unlocked at first.
Yes I did this I put non-att Sim card and it requests an unlock code
Before flashing it was working 100% without att Sim but now NO

Were able to use the phone with another carrier's sim card? After fixing your phone, it will only work with an AT&T sim card?
Yes it like this
I am wondering from where could I get back the unlock code.
Any way any idea

Did you buy a code? If you did, the unlock code would not have changed as long as the imei did not change.
If it was unlocked when you received the phone, you'll have to buy another unlock code.
I'm surprised it became locked after it was bricked. I didn't think this would happen.
Are there any firmware for unlocked sgh-i747.
Sent from my HUAWEI Y511-U30 using XDA Free mobile app
If you are on a stock ROM that is 4.3 or higher, you must buy a code.
