That freedom that Android gives users allows the complete system to be modified practically to customize it or to install whatever we want. Some see this as a problem, while others see it as a doorway to a host of possibilities, and it is precisely that Android freedom that a large number of users appreciate. Thanks to it, in fact, we can unlock our mobile without having to pay for any SimLock code. We are going to explain how you have to do it, but first of all, we must indicate that it is not compatible with all smartphones, so some in particular may not be released after this process.
Besides all that, several things must be said. It is a process that could be illegal if not done with the proper permissions. The contract with our operator must allow us to release the mobile. If the stay has ended, no problem, but we have to be sure that what we are doing, whatever the conditions of our contract, is legal, allowed and we can do it. On the other hand, even if it is legal, it is likely that with this process we have lost the warranty of the phone. The operator will never be responsible for any possible damage if we have released it, and neither will the manufacturer, because to get there, we will have to have rooted the mobile. According to the law, we should not lose the warranty if the error is from the factory and has nothing to do with this, but it could be very difficult to claim to get the phone repaired. Nothing has to happen with this process, and if you have already rooted your mobile, it is likely that you accept these risks, but we want you to be aware that we can never be held responsible for the possible consequences of carrying out this procedure.
This process could be useful for when our contract has passed, if we do not want to have to pay to get the unlock code, or when they give us a code that is not valid and does not work, leaving the only option to take the smartphone and send it to a technician.
Root, is the only requirement there is. We have to have a rooted smartphone, with Superuser permissions. Rooting each of the smartphones is a separate case, and a lot of information can be found on the Internet. Rooting a mobile also carries its risks, although it allows us to obtain greater control over the terminal and expands the possibilities we have.
We are going to carry out the entire process from a terminal. We do not have any pre-installed on the smartphone, but it is easy that at some point you have installed one, that is probably worth it. In any case, we are going to use Android Terminal Emulator. Once we have downloaded and installed it, we just have to run it, and start entering the commands that we mention below, pressing Enter after each one of them to continue.
– su (with this we are requesting the Superuser permissions, which will execute an advantage of the Root application telling us if we want to give them to them, something we access)
– cd / sdcard (with this we move to the SD memory of our smartphone)
– mkdir code (the word “code” can be replaced by anything, but we have to remember it to use it in the following steps. We are creating a folder with that name)
– chmod 555 code (now we are giving read and write permissions)
– mount -o nosuid, ro, nodev -t vfat / dev / block / stl5 / sdcard / code (we are going to move all the files we need to the folder we have created)
– cat /sdcard/codigo/mits/perso.txt (the unlock code of our smartphone will now be displayed. This, we must write it down in a safe place so you don’t lose it.)
– umount / sdcard / code (if we do not find problems after this step, we can start the next step without problems)
– rm -r code (we delete the folder we created initially)
– reboot (we reboot the smartphone)
Then, the only thing necessary is to use a card that is not from the operator with which we have purchased the smartphone and put it in it. When we do, it will ask us for the unlock code, and that’s when we have to enter the code that we have written down. Yes, first you have to eliminate all the zeros at the end, and the first six numbers that are an ascending sequence, thus keeping the eight digits in the center.
