I have an S3 that displays this message when I insert my SIM card: PHONE NOT ALLOWED MM#6
Before any one starts jumping to conclusions, please hear me out.
Did I do an IMEI check? YES...I called AT&T and met with the seller at an At&t store. The seller was the original owner. I even inserted my SIM card in the store. Since I never seen this ERROR before, I figured I could just downgrade the phone like I always have.
What Android Version? The phone is currently on 4.3. Now that I'm home and spent the last few hours doing research. I now know the phone can not be downgraded. UNLESS someone knows otherwise.
Since the phone has not been reported stolen, and current downgrading methods are not available. How can I get around this ERROR?
Could it be it not NETWORK UNLOCKED?
THANKS IN ADVANCE!!
Go to XDA general and look to see a thread called working downgrade. That might help you.

THANKS!! I was just reading that. Theres a possibility I may still not be able to unlock. But, I'll give it a try.
You can't unlock but that may help you seeing as the issue never happened before

Does the phone show the same imei # as the label located in the battery compartment when you dial *#06#?
You are correct, you cannot downgrade the bootloader, only the ROM; therefore, the free unlock method will not work. You'll have to buy an unlock code. To unlock it using a code, make sure you're running a stock ROM.

Alright.. been working at this for the last four hours I'd say and I still have no luck so now I've come to the experts for help - of course that's you guys!
I bought an carrier unlocked T-Mobile G2 off of eBay and heres what I've done currently:
Put in my SIM, didn't work so I came here
Rooted my device following this tutorial
Loaded a Modaco HTC Sense ROM on my device - STILL NO Network Connections
Put CyanogenMod on and still had No Network
Did the gfree unlock, and ran the ADB codes to check everything everything was good
These are the guides I followed..

ALSO I DID NOT HAVE TEMP-ROOT when I went to PERMROOT!
Please can someone give me some tips?
Need some more info from you. Lets start with your last comment about not having temp root. If you followed the first guide you linked you did in fact have temp root first.
Now i need to know where you are at now. If you got the rom flashed and everything is working xcept network connections you need to first check your apn settings. Paste those here so we can see what you got goin on. Also there are a few posts about your problem, im gunna check them out for you as well

Hey,
Yeah after re-reading the rooting thread you are correct I did indeed have temp root. As for APN settings I'm not sure what they are I'm researching at the moment.

Carrier Unlock
For all you people trying to unlock your G2's for use with any carrier. All you have to do is call T-Mobile and request it. I did it on my G1 and I've done it on my G2.
There are certain requirements and stipulations but I'm sure the majority of you will meet them.

I wouldn't do that if I were you. There are plenty of postings from people who unlocked their phones with unlock codes, and ended up with a phone that won't pick up the network.
The gfree method of unlocking the phone is actually safer than the carrier's own method !
Yea it was a factory unlock that is screwing up this guys phone. Maybe..... if your phone isnt reading a sim card you might need a replacement. Have you tried any other sim cards?

Really? I've been with T-Mobile for years, I always unlock my phone from the carrier directly, and have never had any problems. I've tested it on a few SIMS successfully and I don't expect any issues when I go overseas. I guess we'll see. What issues have you heard of?

It's a program developed by the great guys at #G2ROOT that gives you full radio S-OFF as well as doing a SIM unlock.
The next thing i would do is get yourself a new tmo sim card. If your g2 is reading the rogers card then it should read you tmo card. Can you test your tmo card in another phone? Alsoo do you have a connection with the rogers card?

I don't live in the states, and the Rogers card is being identified but it didn't have service so not sure.
I have a question. Did the phone ever work? Before you started anything. If not you have been doped by an ebay seller. I would suggest contacting the seller. If phone did work and now doesn't I would recommend you try entering your apn settings manually.

The phone worked perfectly in the United States, but he only used it with T-Mobile and he didn't try another SIM card (AT&T for example)
Update
My Carrier unlock code from T-Mobile worked fine when I traveled to a couple of different countries recently. Guess I got lucky!
Hi, first post here. I need help unlocking my Samsung Galaxy S2.
Details of the phone:
Android Version 2.3.7
Baseband version: I9100UMKG2
Kernel version
2.6.35.7-g1e46077
[email protected]#1
Mod Version
CyanogenMod-7.1.0-GalaxyS2
Build Number
GWK74
IMEI:
***
So, I went to an unlocking place in London, were they used all kinds of software that would supposedly unlock it, but it didnt work on any different carrier other that the one I have it on. I have a plan on TELCEL from Mexico for 18 months. I tried a second place and they still couldnt do it, even with the Samsung Software. So I rooted it, flashed it, and put CyanogenMod in it, and downloaded two apps that supposedly unlock it, one was the app done by ChainFire, and the other one by helroz. The chainfire app couldnt find the code! Helroz did nothing after it restarted. Also, I tried putting a code but only twice, so the phone still works fine and has chances for the unlock left, I believe.
One important thing to note is that with the old software that came with the code it wouldnt even as for an unlock code, but after rooting and putting cyanogen mod in it, it asks for an unlock code. Thats basically all ive done to it.
So, is there any way I can unlock this phone? And has there been cases were a phone is just impossible to unlock no matter what you do? I am desperate here!

ok sorry about the IMEI ,and thanks for deleting it. So any help guys? PLEASE! Helroz and Chainfire not working. What else to do? Is buying one of those codes on the net a reliable way of doing it? I dont want to buy one and then find that it doesnt work...
Mexico is nasty with this they often deliver the phone 'broken' (they do this on purpose) making unlocking pretty much impossible.
In Europe doing this is illegal but well in Mexico (latin america) it isn't. I have seen this with Claro in Peru also.
You can try with SRS software (unlocksamsungonline.com) but contact support first to tell about your problem.
Also I suggest removing the modded firmware because that has probably only made your problem worse. Put a non branded original firmware and check if your IMEI is still intact.

I can vouch for his service, used it before...
I will try the links posted. The weird thing is, that when i do the *#simlock# on the phone, it shows all the options in off, as if everything was unlocked. But when I put in a new sim it says sim lock! What can I do? Is it still worth buying an SRS account and trying to get it unlocked? I dont want to spend 14gbp and then have the thing not work... Any ideas? I have also reverted to original software now. I need more options >(

you sure thats not a simpin not network lock? or the sim unlock pin was entered wrong now the sims blocked... got another sim to try?
Yeah ive tried other sims too, not working. ALL the locks show as off, but not working! I think the damn people just "broke" the phone and modify it so its impossible to unblock? I dont know what the hell im supposed to do... Tried almost every cable method out there, but not sure if to spend like 15 pounds more to get a code? I dont know if it will work... ANy other suggestions guys!?

The thread I linked you two, he has a UST Pro II, it's a hardware unlock solution... Phone must be on GB or less, and rooted, he shares his UST's USB connection over network, and carries out the operation on your computer... Msg him explaining the situiation and see is a refund possible if it doesn't work...
Great topic mate!:good:
Hey guys,
So I got the SGH-I747M from Bell Canada today, its supposed to be the exact same asthe AT&T one hardware wise but some slight software difference I guess.
Anyways, when I try to use *#7465625# to check my network lock status the code doesn't even work to view the Personalization Status, I remember reading on the international forum section a few people had this as well and someone else posted a different code that does the same thing, but I can't seem to find it anywhere when trying to search, does anyone know what the alternate code is to check? or if perhaps the fact that the first code doesn't work means the phone wasn't locked to begin with at all?
Thanks.

Thanks but that doesn't answer my main question of why the code doesnt work to display the status. anyone else know why or an alternate code?

So far my best guess is that my phone wasn't locked to begin with if the code doesn't work, anyone else with Bell or other Telus/Rogers phones able to use the code, does it work, does it not?
Yeah, tried doing the same thing does not work comes up with "Connection Problem or Invalid MMI Code"
I plan to unlock my phone via cellunlocker but I do not have a SIM card to force to the unlock network screen

I've actually been working on getting the lock status code working on my NA variant S3, I've gotten as far as actually being able to load the lock status Page but no information on what is or isn't locked because of how our NA models are not the same as the international model in regaurds to the nv data bin files.
I haven't said anything about it until now as I didn't want to get anyone's hopes up as I don't get much time to work on this. So it could be some time before I have any good results if any. I'm still a newbie as far as being an android dev.

if code does not pull up page you cannot assume phone is unlocked that is poor logic. even unlocked the page should pull up, perhaps with a different code. unlocked phones in the us can still pull up that page.
I would like to know this also. I just sim unlocked mine and would like to know if it worked.And dont have another sim to try?
According cellunlocker.net, the code does not display the lock information on the NA versions of the S3. You have to use a non-"insert carrier name" sim in order to see if the phone is locked and then enter the unlock key. I got mine from cellunlocker.net; cut my used Tesco sim to a micro-sim and boom it worked.
Code doesn't work on At&ts GS3 as well. I unlocked mine yesterday after at&t gave me the unlock code...but only way to check it is by using a different sim.

I got this phone as a gift from my sister using her upgrade. Its maybe 40 something days old....(the phone) ....Ive heard if you're in good standing with At&t (ie: always paid your bill on time...pay over $100 on your monthly bill)...you're treated better maybe? Idk. I just called 611 and asked "may i please have the unlock code for my device"....I answered their security questions and made small talk.. "hows your day going"....mins later......"heres your unlock code"...

My Experience
I used cellunlocker and got an unlock code last week and ordered a T-Mobile sim card ($0.99) which came today. After some careful cutting (I ordered a full size sim card) I inserted the T-Mobile Sim and the S3 booted to an "enter unlock code" menu. I entered it in and was able to immediately access T-Mobile.
I get the same "Connection Problem or Invalid MMI Code" when I try to check but I know it works because I was on the T-Mobile network. Somehow I my text messages and call history for today only were erased so you might want to back up that data before you try it out. Pretty easy process overall.
Long story short - I got screwed over today.
I sold my Nexus 4, and bought a Brand New still in plastic Note II today off Kijiji (Canada's craiglist) for $480.00
Its locked to Rogers, but seller said he unlocked the phone to sell it. I powered it on, it worked great and still had all the plastic on it.
I brought it, got my Microsim out, got it activated with Telus, put it in my phone and boom - Its locked. Realized I made a huge mistake not trying the Sim before buying the phone.
Emailed the seller, he said he was told it was unlocked and I'm out of luck, sell it or unlock it myself. Wow... I couldn't believe it. He hasn't responded to anything else since. He told me he already spent the money on a iphone5 so good luck with it. Shocked by the response.
I called Rogers - explained the story - gave the IMEI. They told me its a brand new activation - she said she can't tell me much but felt bad so she told me it was literally a brand new phone but was subsidized so they can't unlock it for 90 days, but did ensure me if I decided to use it with Rogers it would work. (She all but told me it was just activated this past weekend by the seller, so it was 1-2 days old). She said after 90 days I could get it unlocked for $50 but need to be a customer to do it. Well isn't that helpful.
So now, I tried Cellunlocker.net and quickphoneunlock.com to get it unlocked. She recommended me try these. I had used these services many times in the past without issue... well this time, both providers gave me the exact same lock code - but were unsuccessful. Still waiting to hear back from both services.
I then found the "free unlock" method on XDA and around the net, but the last step's menu isn't present in my phone so it won't unlock. This step to be exact - "choose [4] NW Lock NV Data INITIALLIZ"
Anyone have any idea's on why "choose [4] NW Lock NV Data INITIALLIZ" isn't in my menu options? Or have any other unlocking suggestions?
I'm basically down to one option - switch to Rogers - which is a Major pain in the ass and something I'd like to avoid.
Yes I know I made the mistake of buying without testing the sim first, Please no need to comment about this.
My phone has 4.1.2
It updated as soon as I enabled WiFi.
Seems if i Left Rogers 4.1.1 on it I would have the option to unlock, correct? Anyone tell me if I can go back to 4.1.1 somehow and if this would fix it? (Rogers Canada) And how I can do it?
Having some bad luck here.

That is correct. Go to www.sammobile.com and get the stock 4.1.1 firmware for your phone. Flash it with odin and then follow the steps for the free unlock guide. Make sure the firmware you download is for the canadian model . I believe it will be sgh-i317m . Once you get it unlocked then you can go back to 4.1.2 and it will stay unlocked forever. Make sure you read everything. I dont want you to brick your new phone.
Sent from my SAMSUNG-SGH-I317 using xda premium
Correct. Starting in 4.1.2, unlock is blocked. Downgrade to 4.1.1 and you can unlock for free. It's been proven to work in many many forum posts.
Thanks all
I flashed back to 4.1.1 using Rogers and the unlock code I bought still didn't work, but the free method worked! Phone is now unlocked.

Hi, I am having trouble with unlocking a S3. I know for a fact it is not unlocked and when I put in the #.... stuff in dial pad, I go to UMTS, phone control,etc. I don't have the 4th option appear and I always see: "SHA256_ENABLE_FLAG [0]." When I put in an AT&T Sim, I get "enter unlock code." Something is wrong. It is a blacklisted phone, but my last S3 was blacklisted temporarily. I managed to do it before, so what's wrong now?
