When I input the code to check if my gs3 is locked I get ussd code running, then connection problem or invalid MMI code.
The code I use is *#7465625# and I have to press the call button. I am using the stock dialer.
I have used voodoo to unlock the sim network and think this is the problem. I have flashed a stock firmware but this has made no difference.
Please help...
Voodoo uses the information from the operating system whether the phone is locked which is identical to the one displayed with the code.
So if it says it's no longer, then it's no longer.

I found that the code stopped working in LFB.
If not mistaken, Voodoo only stopped working since LG6.
So it may not be related.

first off when i input the code i get nothing, nothing happens.
when i call the code this appears "Connection Problem or Invalid MMI Code"
i searched for solutions but nothing
help pls
Codes only work on touchwiz firmware, aka. Samsung stock or modded if I remember correctly.
Also, if you're using other dialer than original you can get same error.

Hey folks,
I really badly messed up my EFS recently, with broken IMEI and S/N. It took me a few days of searching, reading and trying before I finally could restore both IMEI and S/N.
Part of the problem was the XXEMG4 EFSv1 to EFSv2 change, and I lost the backup'ed EFSv1 files (of course I did NOT make an EFS Backup when I got my I9300, shame on me).
So now I face another problem that very likely is related to the above story:
I wanted to flash a Cyanogen 10.2 nightly via mobile Odin but it froze, so after 15min with no progress I rebooted to download mode, flashed Phil'z Touch recovery and reflashed Cyanogen after full wiping.
It booted properly and asked for the PIN, but the correct PIN wasn't accepted anymore. There was no "Wrong PIN" or anything, the same SIM unlock screen appered again. "sim/rmei(or rmid? Anything like that starting with R...) locked" was written at the bottom of the screen.
I shut the phone down, removed the SIM card and booted straight into Android.
In the settings I found my serial no being altered, something starting with 4f..., it was also longer that the usual serial. To me it looked like a hex number.
When I reflash the stock image everything's fine... I haven't tried to flash another rom yet, maybe that's still an option?!
Any other ideas save for "take it to a repair shop"? Unfortunately there aren't any around my town...

Previous unlock methods no longer work with efs v2, there is no solution at present other than unlock code from your network provider.
So, I've tried to flash AOKP now, same problem. The full text is "SIM/RUIM card is locked. - emergency calls only".
I'm not certain, but i think this is the default text in the SIM unlock screen.
No matter which digits I enter, when hitting ENTER the PIN field gets cleared. Even with a wrong PIN there's no "Wrong PIN" warning.
The IMEI is still correct, but the S/N has changed, now it is 4df772e33ef0cf19.
I remember similar problems with my Desire HD when flashing an AOSP kernel on a Sense based rom...

I have a Verizon galaxy note 2 and I ordered a t mobile sim card so that I can unlock it and use it possibly on another carrier. When I put the Sim in and dial *#197328640# I get ussd coding than an error comes up of invalid mmi code. I try again and the same things happen. I have my phone rooted but have stock Rom on it and android 4.1.1. Any help would be appreciated. I have attached a screenshot of my baseboard versions and such.
Could use some help unlocking my Galaxy Ace S5830.
I was following instructions from this thread.
It's locked to Virgin Media, I don't have my original SIM but I have my mothers which was a Virgin SIM and I put that in and was able to get mobile data and make calls.
The two codes I could find in bml5.img were:
15362914
80460902
Not knowing which was correct, I tried both multiple times.
It says something like "USSD Code running" but then says "Connection problem or invalid MMI code”
I get the same “Connection problem or invalid MMI code” even when I dial *#7465625# to check if the phone is network locked.
#7465625*638*80460902#
#7465625*638*15362914#
So I was trying these, I read that adding , at the end can help, it didn't.
Tried restarting the phone a few times, checking service providers and it shows a list of about 4 but all but the one the SIM is for say (restricted), so it didn't work.
Tried a new SIM in it, still asking for unlock code when phone starts up.
Any ideas?
I went and paid for an 'unlocker app', and all the app did was read the .img file and give me the two damn codes I already found myself and told me to put them in the unlock screen when I turn the phone on, but having already tried that multiple times it didn't work.
Is there any other way I can unlock it now that I have the codes?
Thanks in advance.
Does your phone need to be on a stock/non rooted ROM for the unlocking to work?
Hi, I recently pruchased a Samsung Galasxy S6 Edge and bought a unlock code from eBay. When trying to enter USSD codes I get the same error everytime 'Connection Problem or Invalid MMI Code'.
I have looked online and tried the common fixes but no joy. Even trying to run a basic *#06# gives the same error. I have tried using a combination of + and , etc before the first digit and after the whole string but still get the same error.
Any ideas? It's driving me mad.
Cheers

With some carriers external codes wont work, so which network is the phone locked to? Contact whoever it is and get it unlocked that way.
Good luck
Hi Duncan, many thanks for your reply. I didn't realise that, I will contact Vodafone in that case. Many thanks.
