NEED HELP - bought phone on craigslist INVALID IMEI?? how to fix?

[Floods7]

I bought a brand new S3 Unlocked phone off ebay, or so i thought it was brand new. It has the screen protector and everything still on, just like from the factory.

I went to activate it on tmobile and was able to make calls but no interent. After doing a little research and talking to the tmobile support guy i found that the IMIE is invalid and that the phone is rooted. I am quite good with custom ROM's (windows mobile days) and am confident in my ability to root and change the ROM. With that said, what can I do to make this phone work?

This is the info on the device:

Model number i9300
Androiid version 4.1.1
baseband 6577 dual core
baseband version MAUl.11.AMD.W11.50.SP.V12, 2010/09/20 18:56
kernel version 3.0.13 root@liyunpen-desktop#1
Build number AlPS.ICS.MP.V2.6
Custom build version 000120927

IMEI info:
IMEI(slot1) - unknown
IMEI SV(Slot1) -78
IMEI(Slot2) - unknown
IMEI SV(Slot2) -78

Serial number - not available

Now if I go under the battery the info is as follows:
MODEL: GT-i9300
FCC ID: A3LGTi9300A
SSN: -

I spent alot on this I hope its not 500 down the drain

Ok, can you point me in the right direction?

How do I do that?

Also there is other stuff missing such as the serial number. How do I change that?

I would like to just fix this and sell it, can anyone tell me how to put stock ROM back on this phone and set it up so I can sell it?

first thing, remove your imei and Mac address etc, you should never post it online

Ok i edited it, now what? How do I get everything back to factory settings?

The phone looks like a fake to me. For a start the I9300 it's quad-core not dual core, and the information you have taken from phone settings is all wrong.

have you tried a factory reset it going back to stock room. Op btw you're in the wrong forum. There is a forum for American models.

I remember seeing that baseband version, or something similar in a thread about a knockoff phone, but I can't for the life of me find it...

Also that kernel version to me makes it sound very much like you got yourself a Chinese clone...

 

[Floods7]

This is an unlocked model, the tmobile guy said this is international. Do I have to post somewhere else because it is international?

What do you mean fake? it says Samsung on the back cover, it has the Samsung factory screen film still on it, plus under the battery it says Samsung.

What should I do from here? Do you guys need anymore info?

Isn't MAUI just some sort of clone thing, whereas MIUI is a legitimate custom ROM?

This IS the international forum. You're in the right place.

Please provide us with pics of the phone and screenshots of system info screens and what the operating system looks like!

you've been ripped off mate. No s3 has 2 SIM slots. The T-Mobile guy probably hasn't handled the int'l model yet or he didn't want to break your heart. And since it said I9300 he didn't look into it.

This is how an international model looks. And i realized your baseband was 2010...That's impossible.

You have to report the seller and get a refund asap.

and I got it on craigslist, not ebay. I am thinking i can sell it on ebay as long as i list it as invalid imei. But I dont even want to go there now. I want to get this fixed

 

[kofiaa]

You should also cover the serial number, how many SIM slots? It looks very much like a Chinese build with the device info you showed.

You see how the build number is ics, but the android version is 4.1.1

If it's a fake, it's a pretty well done one... I have to say that.

Does it actually have two SIM slots? If it does, then it is fake, case closed.

Of course the device info is just all screwed up... So that part really screams fake...

Can you get into download mode? Turn the phone off, then press volume down and the home button and keep them pressed while you also press the power button until it turns on, then release all buttons.

If you can get into download mode, you could try flashing a stock ROM with Odin, but of course if this is a fake phone, that operation might completely break it. On the other hand if it is a fake, it's pretty much worthless anyway.

I really don't feel very qualified to give you a lot of advice in this matter, and I'm a bit scared of pointing you in the wrong direction.. I know there are many guys here who are great at identifying fakes. I hope more people will find this thread and get you a definitive answer...
