[Q] Phone not allowed mm#6 error message - AT&T Samsung Galaxy Note II

Phone: SHG-I317
Carrier: AT&T
Current Firmware: 4.1.1
Hey guys, I purchased this phone and have yet to officially activate it. I downgraded from 4.1.2 so that I could unlock it to work on other networks. I did the unlock procedure and I attempted to put in a METRO PCS Sim card but I get: Phone not allowed mm#6. The phone is not blacklisted as Ive checked numerous sites online and even went to a AT&T store and they were able to pop a AT&T Sim card in and it worked just fine.
I tried to search this issue but the only thing I can come up with was that it could possibly be blacklisted but Ive ruled out that possibility for now.
Could it be that the unlock was unsuccessful and I need to do it again? But then how am I supposed to know that it was successful without another carriers sim card? is there something that changes in the settings or something?
Thank you very much for your help.

[Q] Regarding the S3 Unlock Method

Not trying to sound noobish but need assistance on this Unlock Method that was posted here http://forum.xda-developers.com/showthread.php?t=2014982&page=1
Using the AT&T Samsung Galaxy S3 SGH-i747 version, the method worked however here is the dilemma.
I pre-emptively ordered an unlock code from an unlocking site. However, I stumbled across the above thread this morning and performed the procedure which worked and switched over to T-Mobile Prepaid. Given I heard T-Mobile is "re-farming" their network now, I am getting EDGE speeds. I've tried several different APN settings I've found online however it does not assist at all, when I run SpeedTest it comes up with an almost 500ping with .10mbs down and .10mbs up.
I'm looking to revert the procedure, which I went through the "common sense" method of going back in and doing the procedure to cut the "lock" back "on" however when rebooting the device still picks up the T-Mobile SIM and goes right back to their network, preventing me from accessing the Network Code Screen because I would like to go ahead and enter the unlock code I paid for just to have things done the "legit" method.
Things I've noticed on other forums about this method used. After doing so when you have no sim installed it will come up with a no sim card installed alert however I'm showing full bars even when a sim card is not installed.
One thing I have not tried was to reinstall my StraightTalk sim then performing the procedure to see if that will kick it back, will try later this evening and update this thread to show results.
Please help?

[Q] SGH-T889 Metro PCS sim not working

Hello,
Today I bought a Note 2 on Craigslist. Since it was from TMobile I though it was only a matter of putting my sim card in the phone and it would work, I was wrong. The person that I bought the phone from gave me an unlock code that he got straight from T-Mobile, however when i used my sim card the phone didn't ask me for the code, so I assumed it was already unlocked.
I called Metro PCS to replace my current phone (LG optimus 9) with the Note 2, they tried using the IMEI number and they told me that there was a problem, that they couldn't activate the phone, and that I had to go to a T-Mobile store. I went to the store, they checked the IMEI and they say it was fine, the guy also told me that the unlock codes are only valid for 72 hours and the person who sold me the phone requested the code on 01/17/14 which means the code its no longer valid.
After that I tried calling Metro to get the phone activated, it didn't work...
I thought that maybe the phone was still locked so I did a downgrade to 4.1.1 - UVALJ1 (the phone was rooted and it had a 4.3 custom rom) and unlocked the phone using the method of that "secret" menu. I tried using the Metro sim card, no luck. At this point I dont know what else to do, a T-Mobile sim card works fine, I haven't tried with another carrier, however I've been using my Metro sim card in my L9 with no problem, so I don't see why it shouldn't work with the Note 2.
So my question is if anybody has tried using the Note 2 on metro, specifically a T-Mobile one, and if so, how did you make it work?
I am pretty new to all of this rooting and android stuff, but I have done as much research as possible before asking, this is my last resource so hopefully someone can help me. Thank you in advance.
Update: After trying multiple times to activate the phone on Metro PCS it turns out the phone appears on their database as it hasnt been paid in full and theres an unpaid equipment installment balance, that is only on Metro PCS database. I went to T-Mobile and everything was fine on their system, no blacklisted, no unpaid balances, no nothing so I activated the phone with them. Now hopefully the guy who I bought the phone from doesnt decide to report the phone as stolen or lost just to be an ahole.
Im on android 4.1.1 and I want to upgrade but my phone its telling me that I cant upgrade because my phone was modified. I want to upgrade to 4.3 but I dont know if I lost root when I downgraded to 4.1.1, how can I check if im still rooted and what rom do you guys recommend flashing? Thanks in advance

sim unlocking problems

I've tried unlocking my AT&T Galaxy Note 2 using service mode. I downgraded the phones modem to the 4.1.1 version and it worked. I used my metroPCS sim card and the phone did not ask for the code but it said phone not allowed MM#6. When I try to call someone it says emergency calls only. I was wondering if it is because the phone is still under contract or because I'm supposed to use a blank sim card and not one thats already been used. Please help.

Unlocking SM-T217S Galaxy Tab 3 Sprint.

I have the MSL code but when I put a sim card in for ATT and reset the device it says invalid sim card. I never get an option to enter the code in to unlock the device for another carrier. I am stock firmware not rooted. I actually tried loading ATT stock firmware on to the tablet and that didn't work at all. I can't take it to sprint because the person I bought it from is not in good standing with them.
Any help would be awesome!
I know this is old, but did you ever get your tablet sim unlocked?
I have one I have been trying to get unlocked, using an idoneapps unlocking app to debrand and unlock my tablet. I’ve run the app several times and while it got rid of the sprint branding and boot image, and says sim unlock successful, I keep getting invalid SIM card error.
ive reset network settings, my tablet is stock 4.4.2 firmware and rooted.

[Q] Pls Help! Need to determine unlock status asap. Also, USSD codes failing

Hi.
I am unsure if my phone is unlocked and can proceed with porting my number over to Metro PCS. Please help me with advice how to proceed. I decided to move my service to Metro PCS since they are now a Tmobile company and after lots of research, I found that I can use my current phone/software as long as it was unlocked. I recently purchased my Galaxy s4 second hand and assumed it was not unlocked. I had immediately rooted it and flashed a new rom (Insane Kitkat 4.4.4). The phone has been working well. I already have requested and have my unlock code from Tmobile.
When I went to the Metro PCS store to port over my number, the phone did not request an unlock code when inserting their Metro PCS sim card (not activated). They said that my phone may already be unlocked or that it may not need to be unlocked since Metro is now owned by T-mobile. They stated that it may work if they go through the entire registration process, port over my number and activate it but that it would be a gamble. If it did not work, then I would not be able to go back and reactivate my sim immediately with Tmobile since it would then be in deactivated status with them.
I tried to find out if it is already unlocked by *#7465625# but my phone will not run this or any other USSD codes to verify. I keep getting errors when trying any USSD codes. A message says 'USSD code running' then "unable to process request".
A friend of mine has an activated Galaxy S4 on Metro PCS and I tried inserting her sim card to prompt for the unlock code but my GS4 just booted normally then showed 'not registered on network'. It did, however, have cellular signal bars. When I inserted my Tmobile sim into her GS4 it did ask for the unlock code normally.
I am at a loss now..
funny, I like to know if there is a way to check carrier unlock status for simcard without having to put a simcard in.
T-Mobile phones work with metropcs without the need to unlock
Could the custom rom be suspect?
Maybe need a stock rom to get carriers sorted out, then go to custom roms.

I ended up contacting Tmobile and they stated that the phone showed unlocked status already but I think you are correct. I wasn't aware they could tell me this. It was very fast and super easy to find out.
I have the phone working great on Metro PCS now. USSD codes still failing though...
