Ok I know this has been explained all over the place but i really dont know what needs to be done to rectigy my problem. When i first got my phone it connected to Kies on home PC no problems even upgraded. Then my work PC didnt recognise it so co-worker "assisted" and looks like he may have used Odin so it appears it was rooted..i assume..even though i didnt want that. Anyway i have now realised i am unable to do any software update using the phone or using Kies. Kies say" You device doesnt support upgrade. I would basically like to be able to upgrade via Kies or using the phone. I have read numerous things on this topic but dont actually understand what i need to do. I know i have to revert to the original but dont understand what i actually need to do or how to do it. PDA:I9100 xwke7 phone: I9100 xxke4 csc: I9100xeukd1 Please help me revert to original....so i may be able to update via Kies or through phone. Thanking you in advance.
