S2 Sim unlock/relock problem - Galaxy S II Q&A, Help & Troubleshooting

Firstly apologies if this is in the wrong topic or been asked before
My dad has a Galaxy S2 on TMobile UK and it works well.
I originally bought it last year, it was unlocked as it worked when I stuck my 3 SIM card in.
The device was then rooted and then I flashed this leaked JB Rom
Today my dad got a new Ovivo network SIM but the device said SIM unregistered, oddly enough so did my 3 SIM give the unregistered SIM when I tried it and was asking for a SIM network unlock code
But when I tried both SIMs in my Optimus 4x they worked fine.
My first thought was maybe the ROM flash re-activated the Network lock.
So I rooted the S2 and flashed another ROM but still only the TMobile SIM works and the other SIMs get the Unregistered SIM messages
I also tried some unlocking apps like Galaxy S2 SIM unlock, and Galaxy S unlock but to no avail
Can a network lock "reactivate" itself? and would I have to contact TMobile to unlock the device?

I was sure I had tried that one but thought, what the hell lets try it again.
What I did last night was flashed the device back to UK generic stock ICS and let it update itself to stock JB
This morning I rooted the device and installed that APK on Mr Killers post.
Lo and behold one touch and it was unlocked!!!
Thank you very much!!

No Problem dude
that APK is from XDA which is working 100% the version which is on Google Play needs you to pay and then it unlocks

Gotta say as well it was really quick!!
The other unlock apps take time and try generating a code. This was just root and one touch unlock

Indeed :good:

Great ! Thanks

But with the lastest version of app, it says that the device isn't unlock...

Root your device & unlock it again.

My device is already root, i've the CM10.1 since 5/6 months x). But with ICS (CM9) I had already unlock my phone but with JB, he's left...

Unlock it again, you're not making any sense.
Galaxysim unluck will permanently unlock your device.

You're right, I tried it and it works.
Anyway it's a paid solution: Costs 3,69 EURO and it unlocks Samsung Galaxy S2 in an instant.
Latest Android 4.1.2 it doesn't matter after all. All you need to have before installing GalaxSim Unlock is SuperSU and BusyBox, these 2 are mandatory for a good functioning of GalaxSim application.

Thanks u So much

the screenshot shows that i have it unlocked but when i put another sim card from other company it asks me to ENTER NETWORK LOCK CONTROL my phone was from telcel(mexico) the new SIM its from T-mobile (USA)

Have you flashed the kernel as well which is there in the viper thread separately by the name of boot.zip (or something like that). please report back if you are on right kernel so we could suggest you something else...
well yes i did flash the boot.img in viperxl 2.0.0 rom. I had been using this for a long time on At&t. But as soon as i Country Unlock my cellphone (At&tHTC ONE X +) (as i m in pakistan now) the wifi doesnt work. I thought at first that this was actually an unlock issue but my friend at the mobile market they suggested to use at&t sim and then use wifi.
Surprisingly it did work. Thus the conclusion which they made was that i need a 128K sim since i m using warid 64K and our networks somehow dont support wifi and sim signal at the same time.
So Mortal Eternity my question is that do we have 128K sims in pakistan? or do u have another solution to this problem?
That's the biggest load of sh*** I have EVER heard. Simcard DOES NOT control the WiFi nor does the mobile network. How about providing adb logs with the following: with att sim with Pakistan sim and with NO sim. Make sure you try to connect to WiFi then upload the Iogs
Sent from my One X+ using Tapatalk
hii..i am a little new to this log thing how do i get the logs?
Hi Llior, Your were right 128K sim and 64K sim have got nothing to do with the wifi but the Local Sim indeed provides the wifi_country_code.
As Wifi disconnects as soon as i insert the sim. The wifi only works if i take out the sim and change the wifi country code to US using SQ Lite editor and then reboot WITHOUT SIM or Put the airplane mode on and then reboot, other wise it again picks up PK as the wifi country code from the sim.
Tried all the softwares, WifiFix Manager and WifiCodes but none seem to be working.
I believe that Wififixmanager (http://forum.xda-developers.com/show....php?t=1445766) works on ICS only not on JB. I need a program that :
1) Changes the wifi country code while sim is on.
2) upon reboot still manages to keep the change of the wifi country code.
Thanks & Regards
Optimus.
I finally got it working wifi and sim both together work...changed rom use 3 apps to change Wifi region lol and last but not the least Special Thanks to Mortal Eternity!!. :good:

[Q] upgraded to Lollipop on Ting (sprint based) - gps, international SIM unlock+...

My Note 3 was pushed the Lollipop upgrade. I avoided clicking OK to give permission but after a week it upgraded by itself (interesting...?)
This is bad news for me as I need international sim unlock - which I got via SUU app on kitkat - but now that doesn't work
Also GPS accuracy has suffered and my widget for turning 'Mobile Data' on/off don't work...now it's a 4 tap process (a reaaaaal pain in the neck)
I can put of with the GPS and 'Mobile Data' widget issue (for now), but I REALLY (!) need international sim unlock (sprint refuses to unlock it!) and SUU app is not working on Lollipop.
It seems a root is my best option(I've never rooted), as well as making sure modems go back to a previous version also (not sure which version). What's my simplest course of action to minimize risk of bricking and do a simple 'one touch' root that will allow me to unlock international sim use (domestic US unlock would be nice also! )
Any help is appreciated or a link to specific thread. (Travelling internationally very soon so need to WORK IT OUT ASAP)
If it was unlocked before, your good to go. Oden the m4j modem and do the rest and the apns. Worked for me.
The GT app will be updated for lollipop so the international unlock will work, says the Dev.
but with lollipop i got an error msg when i used SUU. i assumed it didnt work and theres no safe way to know until youre overseas.
And what did you mean with Oden mj4, and do the rest and the apns? 3 different steps...can you please elaborate. Thx.
And the GT app ?
So it worked for you. And what about domestic sim unlock ?
Thx again, Sammy

I ran the ssu app before lollipop and it " Sticks !" I've odened back to KK to take the Ota lollipop, I've used oden to install lollipop, and have flashed CM 12 none of that undid the unlock.
I am in the US on TMoble network with a ting.com sim and the MJ4 radio with the right apns every thing working great. The rest of the steps are the settings in the HiddenMenu.
http://forum.xda-developers.com/showthread.php?t=2593305
Easy to do just follow the steps.
The GT app is another program that did/will do the international unlock and a whole lot more. Dev says he's updating it for lollipop.
Thanks for all this.
Does me having a SPRINT note 3 make a difference (as opposed to your t-mobile)
And where did you get the sotck, KK, lolliops and the CM12 roms - here on XDA or elswhere ?
is the MJ4 the same for sprint as it is for t-mobile.
I assume you did the domestic unlock and all works well ?
Thanks again

SM-G965F/DS (Partially Unlock Problem)

I got my phone from one of the carriers in the Philippines which is locked. So I decided to try out the unlock method of cellunlocker and here's what happened. First they tried to find an unlock code of my phone via my IMEI and sadly they didn't made it and so recommending me to try the software way and decided to give it a shot (desperately to unlocked my phone) and the procees went smoothly though and yes it unlocked my phone and be able to use any sim card, the problem is that it works only as for Call and Text but sadly Mobile Data isn't working :/ for other sim, mobile data works only with my phone's carrier sim. This thing happens when trying to unlock a device? Is my phone still has a possibility to do a full unlock since asking for an unlock code won't popped out anymore? Or I can't do more any unlock method with my phone? Is this good as dead? yay.
You need configure APN. You can check on Google tutorials and data for configure the APN for your carrier.
