Need help ASAP
So my friend ran into my house and gave me his note 2, here's the situation. An unrooted Note 2 was connected to Odin root package, and the wrong file was entered in the PDA slot (an md5 sum notepad file or something like that). Anyways the error message is coming up says "Firmware upgrade encountered an issue. Please select recovery mode in Kies and try again". I can hold down volume down and power and get into recovery still. Should I just connect odin and throw a file into the PDA slot and try to unroot it, if it even is rooted yet. Im not familiar with the Note 2 specifically since I don't actually own one, but thats the method I would have followed with my S2 which is effectively identical. What file should I download to throw in the PDA slot, a link would be appreciated. Thanks again.
