S6 wont start after installing 6.0.1

dejanajdacic · Apr 30, 2017

Hi guys,

please help me. I upgraded my phone to Android 7.0 but I didn't like it, so I tried today to downgrade to 6.0.1. Everything was fine, Odin sad it was a success, but when it tries to start the phone it freezes when Samsung logo apperars and says Sistem u/i stopped working and I can't do anything, besides going back to Download mode. I ve been reading and trying to fix that for several hours now but theres nothing that helps. And I am going on a trip tomorrow so its really urgent for me to fix it. Can you please help??

Go back to download mode. Volume down, home and power. Then hold volume down and home. As soon as the screen goes black. Switch to volume up, home and power.

Easy way is if you see SuperSU and can open it without errors. If it says no apps configured or shows apps in the list, then it's good to go. Or it'll say new user or expert, Normal install or Twrp/Cwm, disable knox.

If not well then it's not rooted.

You will have to force reset it then, Hold ALL the buttons down until the phone restarts. Once the screen goes blank, hold down the button combo to get into download mode, and flash your devices firmware with Odin. Since the nature of your problem looks like a conflict between your personal data and ROM data, you will need to flash everything, this means you will lose all your personal data and everything on the phone (software based) will be back the way is was out-the-box. This includes BL, AP, CP, & CSC packages, you will need to insert the .PIT file as well, but be sure your devices model number and the model number on the firmware package(s) match up before flashing anything! Flash at your own risk.
