Hi!

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...

Appearently not...

So after that i rebooted, the samsung galaxy grand 'logo' appeared, then tried installing some roms, without success.

Help please?

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.

First of all you need a stable 4.2.2 stock firmware working on your phone, I guess the MK3 firmware will do the job. Dig in the forums and you can find it. Flash it.
Then flash a recovery, CWM or Philz.
Make a Nandroid Backup.
Install the custom ROM you wish to.
Make sure you go through the forums pretty deep.
