I was trying to find the 1st quests for Korin, so I started to delete some other missions, after some missions a friend told me what the symbols were for it (Since my English Patch is broken) and it was the last one I forfeited. can i get it back?

Yes

Yes! All you have to do is go back to the quest giver and re-accept the quest!

I can't get the quest back!

Yes you can.....get it from where you got it

I had turned in the 1st part and I don't know where it is!

Use your scouter and scout for quests, then just pick up quests you see.
