iPod touch Please help!!

Hey guys, last night I was downloading a Cydia tweak and it was taking a hell of a time and I just double-clicked home button and changed app, thinking that the loading would just work, then I click home and everything is frozen, I have entered to DFU mode in order to try and "Just boot" because when I do, I get stuck in the pineapple and about 10 minutes later it works again but Cydia nor any other tweak I had works, I have already changed the kernel settings to -v, I have tried restoring but I says that it cannot restore, could anybody help me?
