s5839i bootloop

hello !! so i have a problem. my samsung galaxy ace s5839i it's a bootloop!! first thing i tried was to wipe cache and because that didn't work i wiped also all data!! but still nothing. after that i searched and found that i need to reinstall the firmware . i had some problems going in the download menu , but i manage to get there. now the problem is that odin doesn't recognize it because also my computer doesn't or at least i think that is the reason odin doesn't see it!!! i've also downloaded and installed kies and usb samsung driver but still nothing!!
any idea on what i can do about this?! about how to make my computer and odin to see the phone? or another solution on how to escape from this bootloop?!
thx! :D
