[Q] Problems with sim unlock galaxy s2 I9100, chainfire and helroz unsuccesfull
I am having difficulty unlocking my new (UK) galaxy S2 and I figured this is the best place to ask for help. I have searched the threads on this forum and have not been able to find the answers I need. So I'm starting a new thread.
I have rooted the phone successfully and followed the instructions with the chainfire app and when it finished it said it couldn't find the unlock code. The phone came from Virgin as part of a contract, however the contract has been cancelled and I don’t have a virgin sim any more so I haven’t actually tried it with the virgin network. It might be worth mentioning here that when I put a different sim card in it the screen that pops up asking for the unlock code isn't there. I have also completed the procedure with the “galaxy S Unlock” app created by Helroz and that was also unsuccessful. Because the three steps in "galaxy S unlock" were unsuccessful I have restored the efs folder back to its original state. I have not bothered to try the manual method of recovering the unlock code using the hex editor because after reading this forum it seemed unlikely to work and it looked like a bit of a hassle.
I have tried several sim cards in the phone that work with my friend’s phone. And my phone was unable to connect to any networks. Except, when I tried my friends T-Mobile contract sim card I connected to the T-mobile network but my phone wouldn't allow out going or incoming calls however the data network worked fine! Yes the internet was working through the t-mobile network (wifi was turned off)
Isn't that weird!!!! So it kind of looks like the phone might be being blocked by the service provider but I find that very unlikely because up until a couple of days ago the phone was sealed in its box.
I have read through most of the "[HOWTO] GT-I9100 Free SIM Unlock via nv_data.bin by Odia" thread and there is some mention of a new locking technique employed by the various phone network companies. Does my problem sound like it could fall in to that category??
It might also be worth mentioning that I took the phone to a phone shop to see if they could unlock it. They couldn't, but the guy did check the IMEI number on a website called checkmend.com and that site reported: "checkmend has a record of this item having been blocked by a cell phone network" and "checkmend has a record that this item is currently blocked by one or more cell phone networks". Does anyone know anything about this website and weather it is reliable or not. Like I say I find it extremely unlikely that it has been blocked because I have only just got it out of the sealed box.
I am very frustrated as you can all imagine and I would really appreciate some help. Feel free to ask any questions, I am a bit of a noob but I'm not completely incompitent so don't be afraid to get technical.
Thank you for listening,
