I was not able to switch on my device and when i connected to charger it displayed that the battery was charging and then the apple logo came up then sometimes red color flashed up and sometime blue color flashed up but most of the time with out any thing happening it went back to showing battery charging symbol then apple logo, it continued as a loop. I was not even able to enter DFU mode. After this incident in did not use my phone for past one weak, Now when i connected my phone to charger it switched on and went into DFU mode but when i tried to restore the device by connecting to itunes i showed error code"2009" and so i was not able to restore my iphone and stays switched off.
