So the situation with me - I got Samsung galaxy core duos, i tried to install Chainfire 3d, but now i know it's not working with jellybean 4.1.2. So I managed to install CWM - I made the factory reset, but nothing - the screen is at Galaxy core GT-i8262
I decided to try something with ADB, so I got a folder named platform-tools, I renamed that folder to Android-adb, and I moved it to C:\
When i open that folder in CMD and write "adb" there are options there... but that's it I don't know what to do
So this is my status at the moment - I have download mode working, CWM working (but not helpful) and trying to do something with ADB. Please tell me what should I do... Im almost ready to go and pay money for someone to fix it, but I think I'm near the solution.
