Changing IMEI - Android Q&A, Help & Troubleshooting

Hello everyone, its been a while since I've been on XDA.
Anyways, I recently purchased an unlocked Galaxy Note 4 (T-Mobile). I purchased it from a craigslist seller, and figured everything was okay after I put my SIM card in it and everything was working fine. After a few days of service with MetroPCS, it suddenly stopped working. I called Metro and they couldn't figure out the problem after 3 days. I then called T-Mobile since thats where the phone originally came from and they proceeded to tell me that the phone has been blacklisted due to nonpayment from the previous owner.
So I'm basically screwed now. I have a $600 phone that's nothing but a paperweight.
I've been in this community for years now but I have no idea what I'm about to do.
So basically my question is, if I root my phone and change my imei number to a valid one, would I be okay? Would I be able to register it under the network?
Any help is much appreciated. Thank you!
P.S. I have also posted this under Galaxy Note 4 Q&A

Samsung Galaxy S2 been barred.Please Help

Hi All,
Recently purchased a Samsung Galaxy S2 from Gumtree online. It was only working on o2 network so got at unblocked from a guy at a market stall so that it works on all network sims. It was working fine for about a week but then randomly came up with a message saying "emergency calls only" and I coulnt make or recieve calls or texts even if i changed the sim to o2. The internet was still functioning correctly however.
Called network provider and have been told that there is a bar on it by an insurance company. Tried to get back to the seller but have not been able to contact him. Have reported him but I would just like to know is there any way to unblock this phone at all? Dont want to lose out on all the money spent on it. would it be worth downloading any unblocking applications if the phone has a bar on it?
Please any ideas, comments and suggestions would be greatly appreciated.
Apologies for the long message
Thanks

This forum is for the SGH-I777 (AT&T version, four capacitive buttons at the bottom.)
You're in the UK and bought from the UK equivalent of Craigslist, so you likely have an I9100. This isn't the forum for you.
Either way, nothing anyone here can do to help you - we are all AT&T customers.
Not to mention, sounds like you bought a hot (stolen) phone. Only the carrier it was first connected to can unblock the IMEI and unless you can prove you bought it legitimately they are unlikely to do so. If the insurer already paid out on a claim then they will never do so. Buying from unknown sources is a bad idea.
So in short, sounds like the guy got scammed.

My phone has been blacklisted

I bought my Samsung sgs2 2nd hand about 14 months ago. It came with the box and everything so seemed legit. I've been using it faultlessly for about 8 months in the UK. I moved to Brazil 6 months ago and it was fine over there also.
Now I've moved back and it's not working, turns out it's been blocked on the UK networks. It happened exactly 1 month ago while I was in Brazil.
Any ideas what's happened? It seems unlikely to me the phone is reported stolen all this time later. I'm wondering if there is anything I can do about it?
It seems a coincidence that i've been away and now it's not working in the UK any more.
If I can't do anything legit to get the blacklist taken off, is there any other way around this? (PM me)
Did you check your imei number on a blacklist to find out.
Where did you get the phone from originally.
My guess would be you've bought it off of someone who's got a 2 year contract and they have stopped paying it,that's how you could get that timeframe.
That's how I would never buy any 2nd hand phone.
And I'm not sure if you are allowed to ask for help in doing shady stuff on here.

I think the best solution would be to talk to your provider about this.
As other people have mentioned, that's an issue you need to take up with your provider. There is nothing anyone here can suggest to fix this.
Speak to your provider. Thread locked

[Q] Sort of a Noob Question...

Hey guys. i have what will probably seem like a super noob question for everyone. I have only EVER been on CDMA networks, and only just started tmobile a year ago. and ive only had one phone there, so idk how these things work.
I want a Sony Xperia Z Ultra LTE (GPE or not, idc) but obviously it isnt sold by tmobile. since ive never had to deal with unlocked phones, i ask you all this:
If i buy one from someone on craigslist/ebay, is checking the serial number important like it is on CDMA networks? also, in order to activate my phone, i assume all i do is pop in the sim, but does that move my insurance and Tmobile JUMP plan over to the new device as well?
Sorry for noobing it up guys. lol any help is much appreciated.
First of all, this should be in the Q&A section.
Second, yes, check the IMEI number before you buy it, and the SIM should automatically be activated once you pop it in the Ultra. I can't give you an answer on the insurance part since i'm not american, so i don't know these things work over there.
I am not sure how important checking the imei number on this device would be since since is not a carrier branded device ( many do not even know this phone exists) . Now to the 2nd part: I believe your insurance and jump program will not transfer to the ultra because it is not sold by T-mobile and that program it is only effective with t-mobile branded hardware. My 2 cents. hope it helps. Thanks

[Q] Sim Network Unlock

Hello as this is my first problem with a phone/phone company, I'm confused. I am a long time T-Mobile customer. But my son gave me an upgrade phone cause I am apparently severely outdated. However it is an AT&T phone. A Samsung Galaxy S2 SGH-i777. He moved and now goes with Verizon. So I put the phone in my name by buying a $10 prepaid deal. However its now been over a year & 8 requests and AT&T continues to deny me the unlock code. The phone was never under a contract , it was purchased outright and was a gift a few years back from his father. Now my ancient phone ha taken a crap and I cant afford to buy another one. I have looked into several sites and became a member here thinking I was more edumacted :cyclops: then I am. I just really want to unlock the damn thing. Please help......This is what Ive done thus far.
1.) Updated to 4.1.2
2.) Downloaded and Installed Framaroot getting the SuperSU
3.) Downloaded CSC Select & SGS unlock tool.
Still no unlock code. Maybe I messed up already ..... idk? 2 months ago I was laid off, my savings is damn near completely dry and I need help.( In more ways then 1....bahaha)!! I would like to remove anything & everything regarding AT&T from this device and run Google or WHATEVER. Is that possible?? I Thank You ahead for any time, advice and help anyone can give. Happy holidays and Namast'e :good:
Unlocking is the easy part:
a) Get the relevant information from your son, and use this AT&T website.
OR
b) I used Galaxsim unlock, and have used my i777 on other carriers (not t-mobile), and overseas.
Using the i777 on TMobile? I'm not sure that will work very well.
-The i777 GSM frequencies [850, 900, 1800, 1900] will not communicate beyond 2g on t-mobile network.
EDIT: Apparently T-mobile has refarmed a lot of its 3g+ services to the 1900 frequency, which will allow the i777 to communicate at full speed on t-mobile service. *assuming the relevant refarming happened in your area.
You want to use a de-branded, slimmed down version of the firmware? No problem.
If you like the touchwiz interface, look at cooked or shostock.
If you would like to run an AOSP flavored firmware, then there are several excellent choices in the development forum.
Happy flashing,
-Cyril

Not registered on network/insert sim error PLZ HELP

I will try to keep it short. Phone is not rooted and worked on straight talk for one week then started the no sim error. I have called verizon and straight talk even samsung multiple times. The phone will acknowledge a sprint or t-mobile sim but that's it. I have very little access as you know they are greed out. I am new to all this but have worked for over a month trying to fix this. I have went thru several sim cards and I know the hardware is good. I really appreciate any help as my back up is a J100 and I hate it.
PS imei is fine but samsung serial number is listed as all zeros?
