Yea ive mailed someone already but its 4:58 here so i dont have to expect an answer soon haha, but if i just replace the motherboard everything will be fine ? what about the current IMEI and S/N etc? idk what it al means but its inportant i gues
 
I think IMEI,sn will be new with mother board . Sellers will usually verify that every thing is clean. I have removed mother boards before while replacing busted digitizer, so not difficult. Reactivation of phone with your network should be same as new phone.
 
Joey, if you haven't been able to flash yet, you might want to consider uninstalling Odin temporarily and just installing KIES and attempt to reinstall the original OS through it's recovery feature. Once the phone's native Android OS is installed, you should be able to quickly get passed the set-up stuff to access the Settings and reach the Developer Options to properly root and flash the device. Once that's done you can always try to uninstall KIES and reinstall Odin to try again. You might loose some info if nothing on the phone is backed up (provided your current attempts at flashing hasn't corrupted anything memory wise) but at least it would give you the chance to turn on the Developer's Options and go that route.
 
although my computer recognize when there is something plugged into the computer is does seem it does not recognize the mobile so i cant do anything with it. ill just buy a secondhand motherboard, thanks for the help tho but i really done with this phone.. it just don't work, it died.

You might have to do a factory reset. One of the issues I had with mine was it would freeze during boot up. In a period of two weeks I did several resets to clear it, hope your device is back in service
