I want to update my Samsung Galaxy On7 to android 7.0 Nougat.
The OTA updates haven't been rolled out.
I want to use all legal software that won't void my warranty or get me into Police trouble.
I found this link: http://www.android.gs/update-samsung-galaxy-on7/
I have Android sdk on my computer (all the build tools, and Android versions 5.0.0 to 6.0, and will download nougat also if necessary.
Can anyone please see the link and tell me whether it is safe and legal?
If not, then please suggest any other legal method.
I want to use no custom ROM.
