This started couble of weeks ago when my phone suddendly went to factory mode. it wasent rooted and i was running 4.3 so i took it to the repair center. They told me that the phones circuit board needed to be replaced and it would cost 281€. Since the same phone new was only 299€ i declined their repair. then i went on a search for way to repair the phone my self. I wound some ways but they needed a root acces. So i tried to downgrade my phone back to 4.1.2 but for some reason Odin started to give me this error...

And then when i restarted my phone it keeps giving me yet another error saying that "Firmware upgrade encountered an issue. please select recovery mode in Kies & try again. In kies the phone wont connect to it. it just keeps loading. Now im asking for some help if some1 has an idea or a way to fix this.
I can give more info if needed.
