In theory, the practice that the operators of sell mobiles tied to your own company, it is not a legal practice and we have every right to facilitate the unlock code of the terminal to be able to use it with any telephone company. Do you want to find out how to know if my mobile is free?
But as sometimes this is not just fulfilled, today we bring you the way to free the Samsung Galaxy S4 model GT-I9505, ourselves and completely free.
It cannot be said that neither Androidsis nor I myself are responsible for what may happen to your device, although if you follow the instructions to the letter nothing strange should happen, the only thing is that we will have our brand new Samsung Galaxy S4 completely free and without paying a penny for the work.
How to unlock the Samsung Galaxy S4 model GT-I9505 completely free
The first thing we should do is open the telephone keypad and dial * # # 0011, we press the menu button and in the drop-down that appears we select back or back, we press the menu button again and select the option key input, we wrote 1 and we accept to enter the mode ServiceMode.
Now we press again on the menu button and again ago, in the new screen that appears we will select the first option UMTS.
Now we select the first option again, called debug screen and then the option number 6 PhoneControl.
In this new screen we select the option 6 Network Lock.
Now we select the third option called PERSONAL SHA256 OFF
Now we will return to the main menu of ServiceMode pressing on the menu key and then back or back.
Now we will select the option 6Common and then the option number 6 NV Rebuild.
In this new screen the terminal informs us that there is a Gold Backup, we will click on the number option 4 Restore Backup.
If we have followed all the steps correctly, the terminal will initially remain as blocked, then it will will restart automatically although before that we will be left with the black screen for a while, the blue led on and the two capacitive buttons also on.
This process may take a couple of minutes or three, when you wake up again we will have our Samsung Galaxy S4 completely released and valid for any company, all this permanently and without having spent a penny or without having to learn how to root Samsung Galaxy S4 to release it.

Hi, I'm Marcelo and regarding this release method, I have to say that I have bought two I9505 terminals and curiously one of them was released in this way, but another one whenever I try it gives me an error and does not release.
What will be the problem?
I would appreciate if you would inform me of an alternative method, since I have already tried it several times and it does not work.
It is curious, maybe it is that they have solved the software somewhere and in the first ones it could be done and now it is not.
another alternative method, or wait for an application to solve it, or you do the previous method and when you enter the new sim from another operator, it will ask you for the network unlocking code, which can be obtained after payment in any of the (stores) that offer to unlock your mobile by imei.
Hello, my problem is that it does not let me enter the menu after putting 1 and accepting in key ... help ...
The same thing happened to me. you have to change the rom you have to do it.
I flashed him the xuamdn which is the latest from Samsung, official.
and I could enter that menu, what happens is that even so the tutorial at the end of doing it, and when inserting the new sim, it asked me for the network unlock code.
I mean, it didn't work for me.
instead of 1 mark Q0 and wait a moment sometimes it takes a little time
And followed all the steps, until the screen is black and the lights on, but my s4 is still free. What can I do?
Hello good. With this method we lose the warranty ?? And we can update our phone to android 4.3 (official) when it comes out ??? Thank you very much greetings.
If this method works for you, it does not lose either the official guarantee or the OTA update system.
Hello, very good, I have tried this method but when I give input key and put 1 and then I hit back, I do not get the new menu where the UMTS is ... and now I do not know how to release my I9505: S
I have the same problem that after placing 1 it does not display the main menu. what should I do??
we are 3 with the same problem ... help
Hello, have you been able to solve it?
I have the same problem, I put 1, it does not display the main menu to select UMTS ... how do I do?
For the problem that the Menu does not appear after pressing 1 is because the version of the Mobile Modem does not allow it, you have to download the version to a previous one with Odin, searching in google you will find very quickly the way to do it, it that I have managed to do, but it is true that after following the steps, the mobile keeps asking me for the unlock code of the sim, that is, it does not work for me, I don't know if it is because my rom is 4.4.2, now I go to try to see if I can install a rom 4.2 with Odin and try to do these steps again.
I was wrong in the previous comment, the version I am going to move to is 4.3 Stock.
Well let's see, I put an official ROM without vendor programs, I changed the modem to be able to enter the menus, all this with Odin. I set it to 0 so that it is free, everything is perfect but, in the last step to reset it, it gives me an error screen very quickly and it restarts, but normally, the screen does not stay off and the LEDs on or anything, a normal reboot, and it doesn't catch me….
There I don't know what else to do to throw in the towel. Any solution??
Thank you for your help, if you are a pure informati
… It does not allow me to carry out the 2nd step… because where it says service: Limited… it helps…
Hello, the same thing happens to vico, the menu does not appear, it says service: limited
Hello everyone.
I have followed all the steps in this tutorial and when I hit 'Restore Backup' I get an error message, restarting the phone, which is still blocked ...
What should I do?
Thanks in advance.
The same thing happens to me as carlos, let's see if someone solves it
I don't care that the first ones when putting the 1 stays the same this method is effective for 1 of 20 I think 🙁
Ami does not enter the menu I can only enter the * # 0011 # to the other menu or does not enter
In network lock I only get the first option, PERSO SHA256 Info. No sign of ON and OFF, does anyone know the reason?
Greetings and thanks.
Rafael, the exact same thing happens to me, only one option appears in the networklock, and I can't do anything from there. If you can help us please.
Rafael does not appear the other two options because you are a huelebicho ...
For those who do not get the umts menu, try to put Q1 instead of 0000, it leaves me like this, the problem is when I get to network lock that only info comes out neither off nor on
I see lp myself, the other options are np, how do I do it ???
Hello. Is there a way to manipulate these options via adb? Thanks.
Instead of 1 you must dial Q0000, wait a few seconds and you will enter the service mode 😉
Did anyone find the solution? No trace of On and Off option.
Hello, it is not clear to me if this process "fomates" the mobile. All the best.
Hello, I would like to know if this process is valid for Lima Peru and its mobile networks in my country. I have a s4 9515l and it only reads bitel. I would like to read clearly and move. Thanks in advance
hi, unlocking the imei, isn't it the same as unlocking it
Hello, you have to put Q0000 and it works. regards
Hello, I have android 5.0.1 and I could not do it, but writing the comment asking for help I have solved it by chance, when I got to the screen with the perso sha256, but I have seen that the common option was on the initial screen, and I have followed the steps that are detailed later for that option, and it has pulled to the end and voila, unlocked.
Hello, I need help, it turns out that when I get to the last step, I don't see sha256 off, I only get the first option, sha256 info ... I don't know what to do, can someone help me please ???
The same thing happens to me, I access it with Q0000 but only the PERSO SHA256 info option appears nor a trace of the other options to continue with the release. Let's see if someone can help us. Thanks!
IT DOES NOT GIVE ME THIS PERSO SHA256 OFF OPTION IN ONE OF THE LAST STEPS, IT ONLY GIVES ME THE PERSO SHA256 INFO OPTION
