my eris stuck on skateboard screen. wont do anything else!....prolly cuz i took sd card out of it to use for something else,i got bored looking around on it and decided to delete various folders that i didnt think i needed anymore! phone is old,havent used in awhile. put sd card back in,turned on phone...and skating droids,thats all. phone is PB00100 xc ship S-on HBOOT-1.46 . i have no clue when it comes to things like this but learn quickly. and formatted the sd card! in other words,what do i need to do to get it back to at least working? it has never been rooted,had the 2.1 update through verizon...and what to do with the sd card?
