So i was actually trying to get rid of the upgrade of the operating system i upgraded (from 4.1.2 i think to 4.2.x), because my phone turned into a slow machine, slow as **** sometimes i actually had to wait 10 secs for a respond. And i also wanted to root it.
So what i did is i backed up my phone on Kies, then installed "PhilZ Touch 6", and wiped all its **** in it, you gotta understand i thought its ok to delete everything now because i back up all my things on Kies i thought its safe now to do anything...
So after that i rebooted, the samsung galaxy grand 'logo' appeared, then tried installing some roms, without success.
Additional info: Kies detects my phone when i connect it, even in download mode if that's helpful.
Please show as much examples/information in the things since i am a noob, never actually had a android phone before.
