Will NOT boot. iTunes sees device ok.
3G stuck with only Apple logo. Restored to 4.2.1 with iTunes;shows serial#, etc. Thinks it has music and lists titles but doesn't show anything on screen except logo. Tried redsnow,tinyumbrella,etc. and again thinks it did something but it won't boot to a desktop display; just an Apple, Pineapple or Snowflake. I checked cables going to screen (seemed tight).
What to try next? (Help!!!!!) please.
