repair ipod taht is stuck in black screen or not switching on

if u tried to jailbreak ur iphone or i-touch with blackra1n and got a black screen after the process had finished.it meant that u have spoilt ur i-touch or phone.there is no use of browsing through net and trying to find a solution for that .because there is none for it .the only thing u can do is go to apple official website.call the customer service in ur country .and find the nearest apple centre.have ur i-pod replaced.thats the only way
Even same thing happened to my i-touch 3g.i tried to jailbreak it and everything was fine,the geohost picture too appeared .and it was written that wait for restart.it finally offed and got stuck at the black screen.I could do nothing with it.no tutorials in the net worked.even i-tunes restore didnot work.finally i contacted apple customer service and got my product replaced with in 2 days

thank you
