Touchwiz deleted Galaxy S Duos. Phone doesnt work beyond language setting I have a Samsung Galaxy S Duos with Root access. Recently I removed Touchwiz through Root Uninstaller. After uninstalling, the phone screen went blank. The only thing visible was the notification bar with basic options. 

I tried to restart the device but nothing happened. I recently did a hard reset on my GT-S7562. After reset the phone booted up, I did the Initial set up (language, wi-fi, time). Now a black screen shows up displaying the battery status, time network strength and nothing else. 

If I press the back key the set up starts all over again. No home screen, no app drawer. Nothing except a "black" screen. I tried another reset and the same thing happened. 

What do I do now?
Grab yourself a stock-firmware from sammobile.com or from the xda
forum.
Install Odin v3.XX on your PC, start Odin and boot your phone into the download Mode ( Volume Down + Power ) 
Use Odin to flash the stock firmware onto your phone, wait until it is completed
Restart your device and set it up from the beginning
Optional: Root it again and next time - install a different launcher - you don't need to deinstall the whole touchwiz framework - I'm surprised that the systemui was still funcitonal.
