    How to unlock Galaxy S7 and Galaxy S7 Edge from TIM, Wind Tre and Vodafone and others. With this tutorial we will see how to debrand the Galaxy S7 from TIM, Wind Tre and Vodafone and many others, with a quick and easy procedure.


    The Samsung Galaxy S7 is on track to be the best-selling Android smartphone of all time. It's sleek, fast, and has a better camera than Apple has managed to put on its iPhone.



    Buying a SIM unlocked Galaxy S7 still costs a lot. If you are willing to sign a new contract with a telephone operator, the initial cost of the Galaxy S7 can be as low as € 200. Then you can always choose one with an installment plan from the same operator.

    These additional options will save you a lot of money upfront, but the device you bought will have the SIM locked by the carrier you bought that phone. This is not the best if you decide to sell your device.


    How to unlock Galaxy S7 from TIM, Wind Tre and Vodafone

    Often you want to unlock your device in order not to be tied to a single telephone operator, in case you want to use more than one SIM on your Galaxy S7 and Galaxy S7 Edge. Before moving on to driving, however, some requirements must be met.

    The first is to download Samsung Smart Switch. Then download the latest Odin and install it on your computer. Finally you have to download the SamFirm software from the page on the well-known XDA forum. This procedure is not dangerous for the warranty, you just need to have an official firmware installed on the device to not make it expire.


    Be careful during the installation, because if it stops suddenly, you have to repeat the process, and in this case the device will no longer be covered by the warranty.



    Extract the zip file containing SamFirm and run it. In the model entry write SM-G930F for the Galaxy S7, for a Galaxy S7 Edge write SM-G935F. In both cases, in Region write ITV for the Spanish firmware.

    Check Auto and click Check Update. Once the update is found, make sure that both Check CRC32 and Decrypt automatically are checked and click on Download.

    Now we install Samsung Smart Switch after extracting the firmware in a folder and restart the computer. Now open Odin after unzipping the zip file ..


    Inside Odin you find BL, AP, CP and CSC, each of which references a firmware file (except HOME_CSC, which you can ignore). Select all 4 buttons one at a time and insert the file.


    Now you have to turn off the Galaxy S7 / Galaxy S7 Edge then turn it back on by pressing and holding the Volume Down Key, Home Key and Power Key, until you see the download mode appear in front of you.

    Now you have to press the Volume Up button, now you will start installing the firmware. Make sure Odin detects your phone, hit the Start button and you're done.


    Wait a few minutes and your Galaxy S7 will restart with the unlocked firmware. We at Guidesmartphone are not responsible for what you do with your phone.
