Odin can't see my device after re-partition

After re-partition my i9100 was working just fine, it still is. Everything works fine but when I connect my phone to PC/odin it can't be recognized. I tried everything. Drivers, restarting, formating... I am on the latest rooted stock rom 4.1.2.
Can't install cwm or twrp to flash a new rom...
Please help.
