I got my S7 (930F) today. I went through the 1st time setup and evrythin went smooth until my phone decided to reboot and got stuck in some kind of reboot loop.
As i searched google i read that i was no uncommon problem with samsung devices so i tried some of the things suggested (factory reset/cache whipe) .. nothing worked.

It just tried to boot, loaded my carrier homescreen for a second and went back to the Samsung Galaxy S7 powered by android screen and would do tht over and over.

So i tried to do a firmware update via Kies , looked like it worked but still ... wouldnt boot after.

Maybe the best way would have been to return it to my carrier and get a replace but since i am little bit techy i decided to search some more.

So i ended up flashin

2016-04-18 Austria (3 Hutchison) 6.0.1 G930FXXU1APD1 G930FDRE1APC3

this firmware (found on sammobile) via ODIN 3.10.7 and everything worked but still no boot , still stuck on the Samsung Galaxy S7 screen.

Did i total brick my phone? What else can i do?
Running out of ideas, any help would be great!

your Galaxy s7.. what country/carrier?

22 April 2016 at 18:44 delete

Hello, my Samsung Galaxy S7 Edge just got bricked. I tried to un root it with SuperSU but just go to the Samsung Galaxy S7 powered by Sndroid Screen over and over again.

I am planning to install the official firmware but my phone is the international version, so I do not have a special carrier or a ''country'' so my doubt is, what firmware should I download?

I need the G935FXXU1APB6 but when I find them, there are a lot of different countries with that firmware.

Which one should I download?

Thank you very much.

as long as it's G935FXXU1APB6 PDA.. u can freely use it for international version. Just make sure you download the right PDA firmware for the international version
