My sis i phone can't turn on. I tried to hold the sleep and home button but there was no effect.No matter what i tried it wont turn on or show any sign of turning on.

The i phone will only show an apple logo when i plug in to the charger.Once i off the charger, it wont show any logo or whatsoever anymore.

When I plug in to the PC through usb port it wont have any effect unless I press the home button 5 sec, home+reset 15 sec , home 10 sec , the i-tune will detect the phone but it cant recognize the phone and ask to restore. After i pressed restore it cannot be completed and a message will pop up showing error 1601.. tried to restart my comp and reinstall i-tune also wont help.

Btw the i phone was jailbroken.

Any idea how to solve this problem ?? Thx in advance
