My girlfriend is selling her old Tmobile Samsung Galaxy S2 sgh-t989 that had Android 4.02 on it asked me to clean it up so she could sell it because it ran very slow so I installed Cyanogenmod because its lightweight and also assuming it would unlock it for the carriers. After a bit of reading, on this forum I discovered my assumptions we're wrong. Now my question is this, the person who she sold it to is on AT&T. With Cyanogenmod on it, if she calls up AT&T will they still be able to unlock it or should I flash it with a stock rom?

Better flash stock rom...
I really dont know about carrier locked phones (no such trend in india) but still it would be better or else one may say that the phone has been tempered(correct word??) wid
You can not unlock it on custom ROMs with apps, only from pc at a service store(perhaps), on stock 4.1.2 it is possible with various apps like GalaxSim( I recommend it, altho it's paid nowadays) and Chainfire's app(I don't think it works anymore though)
It's possible, I used the old version of galaxsim to unlock my Telstra locked i9100t and it worked like a charm. I'm pretty sure you can get it free as an apk.

My friend had the an unfortunate but common experience with his X10.
Its an at&r version, and he finally got the 2.1 update only to see "X10 gets gingerbread" plastered all over every android news site. After calling at&t and Sony Ericson, and after being transferred to manager and manager, they emailed him instructions on how to "unlock" his phone to get the gingerbread update.
In the instructions, it tells him that he needs a sim from another carrier. The problem is, in our area, only at&t and Verizon are prevalent. From my old Nokia days, I thought an unlock code was an unlock code. You unlocked the code and then were free to use it on any sim supported carrier with a device with compatible frequencies. I've never actually heard of an unlock that required an alternative sim to complete the unlock process. Nor have I heard of a phone that after it was unlocked, would receive an update.
Is this true? If it is, we have no chance at doing this the legit way. Which method of root, and which ROM would give us the easiest time, and the closest to stock experience. He isn't necessarily the techiest, but loves Sony. Were not necessarily looking for the most features, but would greatly appreciate if he could upgrade to gingerbread.
I'm not an expert by any means, but I have rooted, flashed, and installed ICS and customs rooms on my Transformer mainly using Clockwork Recovery. I've also rooted, flashed a custom over clock kernel, and pushed modified files over ADB on my AT&T Galaxy Note, released a mere fees days ago. This should give you an idea of our experience level.
There are dozens of Roms and sites with tutorials, but they're all convoluted and don't take into account the presence of other methods and rom to explain why their's is better. They also don't tell us when they're outdated.
So, to the point, and to sum it all up: does this sum unlock allow for a blessed OTA update? If we actually need another carriers sim, were out of luck. In that case, which method and rom would be easiest to root, and then flash. Is a from like cyanogenmod (seemingly the go to for handsets) available? I don't have a Rosetta stone for X10 roms , recoveries, and root methods.
Thanks very much.
At&t has no plans on releasing 2.3 I have no idea what an unlock code has to do with an update.
I upgraded my att stock x10 2.1 to 2.3 without a problem. I flashed using the North American 2.3 found here http://forum.xda-developers.com/showthread.php?t=936733 You'll have to look at all the pages to find a working download.
I also got the flash tool from this thread http://forum.xda-developers.com/showthread.php?t=920746

were you able to use 4G after that?
I have the Samsung Galaxy S II i9100M, which is the Bell Mobility (Canada) variant. Same hardware as the i9100 and capable of running roms for the international version; only difference is the crapload of bloatware Bell Mobility had installed on it.
Though a Canadian phone, the phone worked well using a T-Mobile SIM here in the US. After tinkering with Odin and a couple of ROMs I flashed the phone from a stock Gingerbread ROM to a leaked version of Samsung's 4.2 Jellybean ROM, made for the i9100, a couple months before the update on Kies was ready. Unfortunately, I sim-locked the phone, the cause I assume is a missing CSC file.
Does anyone know how to fix this problem? I have been told already by one phone unlocking company that to restore the CSC file I have to flash a new one. Will I have to flash a ROM with the proper CSC file then have someone unlock the device with a sim unlock code or can I just flash a CSC no sim-unlock needed? I NEED HELP PLEASE!!! I screwed up, and it's really annoying having a smartphone that works for everything but making phone calls or texting (the irony).
PICS I HOPE WILL HELP ARE ATTACHED
So I bought a galaxy note for my mom, because she broke her other phone and her contract is up in a month and didn't want to extend it with Rogers. My question is that the person whom I bought it from had it 'unlocked' to work with all the cellular providers here in Canada. So I assume he flashed the AWS bands onto the phone. Leading up to my question, which rom should I flash onto the phone without risking that the AWS bands be "de-flashed". The phone currently has T-mobile ROM on it, so my natural intuition leads me to assume that I can flash T-mobile ROMs onto the phone no problem. But please enlighten me if weather I assume right or wrong.
P.S: The reason I want to flash any ROM onto the phone is that she is used to Vanilla Android and doesn't care for, in fact hates, Touchwiz.
ROMs won't affect the modem/radio unless you install a stock ROM with Odin.
And even if you change the modem/radio the SIM unlock sticks no matter what you throw at it.
Hey guys,
I've been trying to unlock my phone for a few days now. Long story short, I moved from Canada to Japan and now I want to unlock my S3 to use a Japanese SIM.
I bought an unlock code from eBay. I was previous running cyanogenmod but then I was told that rooting will cause issues, so I unrooted my phone after an unsuccessful SIM unlock attempt. (wiped the phone, installed stock TW)
Even after unrooting I still had issues, and was given directions for the Service mode. That did not work either. I have tried many different methods and troubleshooting tips and nothing seems to have worked.
Here are some screenshots of the debug mode, my phone details, and a simple root checker app I installed.

Here are some specs: SGH-i747m Samsung Galaxy S3 on Bell running official firmware 4.4.2
Thanks for reading, and I really hope someone can help ;_;

My first thoughts are that since its from ebay it might not be a real unlock code.
I have had a lot of difficulty unlocking my GS3, as well. I actually got the codes from ATT, my carrier. I've tried 4 times, each unsuccessful. It says that after 5 failed attempts, the phone is forever locked to ATT, so I'm afraid to try that last 5th time. I was wondering if you could root, and then unlock more reliably. Is that possible?
Root makes no difference, you probably don't have an i9300 if you are on ATT.
1st post here so hope this is the right place to ask this and please be gentle
I have a Virgin Mobile UK Samsung Galaxy S3 i9300, running stock 4.3, I9300XXUGMK6
I want to install a custom OS on my S3. The phone is almost out of contract, 3 years old and is running really slowly on the stock rom with awful battery life (I have tried a new battery). I previously rooted and installed custom roms (cyanogenmod, slimkat) on an old i9000 and was blown away by the massive improvement in speed and battery life. If I get the same benefits with the i9300 then I will keep this phone and go sim-only rather than getting a new phone. The i9000 was unlocked...I guess I need to check the i9300 is too?
As far as I can tell I need to root using Odin 1.07 and Philz Touch recovery. However, I am confused about what version of S3 Virgin UK provide- I have found guides on how to root and install custom roms on Virgin S3's but they refer to models such as Sprint or SPH-L710- I'm not sure what I have, how to check or how this differs US to UK. I have searched on here and more widely and cannot find an answer to this.
Recommendations on what custom OS to install also welcomed
If it says i9300 under the battery then it it's the standard international model, you can flash anything from this forum. Carrier firmware usually add bloat and modem, you won't miss anything from it.
Unlock is by paid for code, don't try to do it free as that usually ends up with a brick, unless virgin supply unlocked handsets.
Follow the guide in general forum, sticky thread on how to flash custom recovery then custom rom. Root isn't needed if you are going to custom rom, they all come rooted.
