maclaw.pl has good instructions and downloads for all the tools including good quality ROMs for i8190N (although NFC may not work) - same model as my phone. I bit the bullet and went custom only last week, happy with Carbon at the moment
If you want better instructions with pictures, just google "flash a custom ROM with Odin" or something similar, there are plenty out there.
Thanks man for your answer, really helpful!
I searched for some instructions on Maclaw's website but I didn't find anything... Maybe the instructions are included in the ROM archives? (edit: found the instructions
On many tutorials people were saying that it is needed that the phone is rooted, you sure I can install cm 11 without it? Also, they were talking about some apps like ClockworkMod, is it not needed too? (i don't have any SD card)
Anyway thanks I'll take a more deeper look at that tomorrow
