[MOD] SGS4G Carrier Unlocker (Nov 7)

FBis251 · Sep 15, 2013

I'm glad you got it working. I haven't updated the busybox installer in a good while, and some ICS+ recoveries might not like installing it.

I've been working on a native C binary that gets you your unlock code which doesn't have any external requirements. I think the script manager method might be easier for it since AROMA can be unstable at times.

Thanks, but asking about IMEI

Hi,

Thanks for the work in this phone. My question is kind of noobish and I appreciate your patience answering all of the questions in this and the manual unlocker thread.

Is it common for the IMEI to read 00000000000 after this procedure? I can re-lock and restore and the IMEA comes back But while unlocked the IMEI number is all zeros.

Regards

Dorje

No it's not common. Your IMEI should read whatever it did before the procedure, so it's odd that it comes back after you re-lock.

Do all your phone functions work after unlocking, texting, data, voice? If they do I wouldn't worry too much about it.

Hi,
Thank you for your reply.

It is a t959v (of course or I'd be in another forum) which I got originally as a T-Mobile device. After applying your unlock, and with the IMEI all 000s I can insert my daughter's ATT Sim card in and it works perfectly. Text messages, phone and data all work well.

When I insert my wife's T-Mobile SIM it does not work...

If it helps you to know, just doing a hex lock and rebooting will not bring the IMEI back. With the HEX lock in place, booting with a T-Mobile SIM card in will not restore IMEI either.

Doing an an EFS restore and reboot even without a SIM card in will restore the IMEI. Then when I place an active T-Mobile SIM in the device it will then work for texting, data and phone.

Thus over all I have all of the functionality I personally need. It would be nice in the unlocked state if I could just slip in any SIM I wanted to without need for re-locking and restore but to have to do these things to get back to a T-Mobile SIM use is not really a bother to me.

Having the option of the EFS backup and restore is quite useful and appreciated.

Thanks

Your script didn't work, but the Unlocker program worked

Hi,

First, thanks for your posts and info.

I tried running Script Manager and your script many times, but could not get it working on my S 4G. My phone is a Wind SGH-T959W, rooted and flashed with CWM 6 recovery and SlimBean's ROM. The phone now shows itself as SGH-T959V.

When running your script, the very first line it shows an error, something to do with invalid path (which I didn't write it down and can't quite remember exactly). Then it showed an invalid parameter --r, "Unlock code not found", and then an invalid parameter --p.

I tried for many times, and got exactly the same errors. Then I finally downloaded your Unlocker, and it worked on the first try. Got the unlock code, entered it in and the phone is now unlocked.

Thank you very much. I hope you can fix up the script file for other users based on the little info I have above.

Thanks for your purchase!

Unfortunately the script manager method is heavily reliant on the correct version of busybox being installed. It's been hard to bundle the right version with the script, which is why I had been working on the AROMA version of this method, but that proved to be unreliable too. Basically, the easiest way to try to unlock using the script manager method is to try to get the unlock code after installing Team Acid's CM9 roms since they are the ones I tested on before I released the script.

I had a little more control with the app, and it's worked reliable for almost everyone who has tested it, so I'm glad to see that it also worked for you!

busybox problem

scrip says i have a problem with busybox, I install the busybox that u put in the OP but i have the error.

A little more information would be helpful to figure out what is happening.

You can also just get in with adb and execute the commands in the script one at a time.

Then again, it is pretty likely that the phone in your hands is no longer under contract and T-Mobile will email you the unlock code on request.

Apparently i have the code now, but when I insert the SIM card is not show the camp for put the numbers, what can i do?

My first guess would be that you'll only get the prompt if you have a non-T-Mobile SIM in it.

Hey guys,

I spent some time writing a new unlocker in pure C. It's worked perfectly fine on the 3 test nv_data file I've used so far.

Once I get it cross compiled I'm going to need some testers to try running it for me (since I don't have a phone to test this on). Anyone who is interested please reply.

Send it my way. I've still got two

Well I've posted the source code on github for anyone interested.

Hey guys, I just released version 2.0 of my unlocker app. You can check the details here:
http://xdaforums.com/showthread.php?t=2243585

As far as the free version, the binary version I made works fine, jeffsf tested it for me and I finally got to test it on an actual SGS4G myself and it works fine.

I've added a nice new feature too, a lock status checker. It will tell you whether or not your phone is unlocked, in addition to giving you your unlock code.

I'll try to have a zip download for you guys tomorrow! It probably won't have all the AROMA goodness, but it'll make it easy for you guys to use script manager to get your codes.

Hang tight!

how do i download the script ?

bajoagua · Dec 19, 2014

Something wrong

Great App, works just fine. But I had a little problem, found the unlock code, but the phone won't take it. Still says Incorrect Code, any ideas?

You can try the unlock method here by hand:

Note that you should make a backup before trying any of the steps in that guide! It does teach you how to make a bml3 backup though, so that should be enough, but make sure to back that file up elsewhere.

You can also try my app. It costs $3 and you can unlock your phone with just a tap of a button.

There is an easier to use unlock app available here:
