This guide can work for almost all modern Samsung devices and not just the S7 FE.
The device will be erased completely in order to install the root.
- You can brick your phone by doing this.
- Can void your warranty. (I suggest rooting after warranty or if your device is a bit old.)
- KNOX can be tripped and some security features won't be available. (WILL DISABLE SECURE FOLDER)
- Some apps such as banking apps and calling apps such as Zoom may not work after rooting.
- A PC/Laptop.
- The device you wish to root.
- An original Samsung cable
- Remove all accounts from the device to ensure security features don't mess our root installation.
- Turn on usb debugging. If you do not know how to do that, check here.
- Download Samsung drivers to ensure the device is well connected.
- This is a tedious process so I suggest charging your device until full.
There is a forum for this. Click here.
If you want to use SamMobile to get the firmware: (you do need to sign up)
- Go to Settings > About Device/Tablet > Software Info and note down the baseband version. This will be required for getting the firmware file.
- While in Software Information, search for "service provider software version" and check the last 3 letters (Device Region). Example: XSA.
- First, you must download 7-zip to extract the md5 file. You may use other tools.
- Then you must extract the files using 7-zip or the software you chose.
- Next, extract only the files which start with AP, BL, CSC, and HOME. (This will take a while depending on the write speed of your storage.)
- Now transfer the AP file to your device. Make sure to put it in downloads on your device for easy access.
- Now, download the Magisk manager apk.
- Open the app and click install which is next to Magisk.
- Click Select and Patch a File and select the AP file.
- After patching, you should transfer the patched AP file (it's usually renamed to Magisk Patched or something.) to the PC.
- After the previous steps, make sure your device is in download mode and connected to your computer.
- Now, download and open the latest version of Odin.
- Go to Options and Disable Auto Reboot.
- Click the AP button and choose the patched Magisk file.
- As we added the AP file, add the default. (BL, CSC, and HOME)
- Click Start.
- As soon as it finishes, exit out of download mode and immediately boot into recovery mode.
- Use the volume buttons to go down to Wipe Data and Factory Reset.
- Click the power button and confirm. After this, go back to reboot now and click the power button.
