Ever since my Galaxy S7 StraightTalk Tracfone did its update and I got Android Nougat 7.0, Ive had nothing but problems. Samsung tells me that I need a software reflash but they arent authorized to work on a straight talk tracphone and there is no authorized dealer in my area who can do it. So I'm hoping someone in here can help me downgrade back to Marshmallow. Please I need step by step instructions for beginners. Thank You In Advance
 
You could do a "Hard Reset" to get the phone back to its original OS. However that will wipe everything on the phone, so you would need to back up all personal data first, and also take note of the apps you have, as you would have to download and reinstall them after the reset.

NOTE: Doing this will clear 'all' the data on your phone, so it is suggested you not choose this option unless you have to, or aren't worried about losing anything on the phone.

Be sure you back up any data you want to keep, to a computer or cloud account, before doing the reset.


To "Hard Reset" the phone...

1. Make sure that the phone is actually powered off.

2. Remove your SD card, if there is one in the device.

3. Press the "Power" and the "Volume Up" buttons, together, until you see the start-up logo on the screen.

4. Once you can see the logo, release the buttons and allow the device to enter the "System Recovery Mode".

5. Next use "Volume Down" button to get to the "wipe data/factory reset" option When in recovery mode the "Volume Up" and "Volume Down" buttons are how to can navigate and highlight what option you need.

6. Once you have selected the "wipe data/factory reset", press the "Power" button to select that option.

7. On the following screen, repeatedly press the "Volume Down" button until the "Yes - delete all user data" option is what is selected.

8. Then press the "Power" button to hard reset the phone.

9. If you took your SD card out in step 2, when the device is up and running again, reinstert the SD card.
