My friend sent over his Iphone saying that he accidentally locked the iphone, so I plug it into my pc using itunes but nothing was detected. Then i tried to plug in mine and to my horror, my phone got locked too. FYI, i am using v1.4. Now whenever i turn on my iphone, it was in blackscreen as if it is in cmd mode. What can i do now?

Go restore mode..

Then update your firmware again.

I cant restore, cz my pc cant even detect the iphone, when i turn on the iphone, it straight away in the black screen mode with "

BSD root : md0 , major 2, minor 0 keep on repeating itself

Are you able to go into DFU mode ?

Sorry for the Noob question, but what is DFU mode? Now 2 iphones are infected. My friend 1 is just locked where u see the picture usb port to itunes ( if u know what i mean) while mine is in blackscreen mode..my USB cant detect both the iphone and i cant recover it, what can i do?

The picture with the usb plug yo the iTunes logo is the DFU mode.
To enter into DFU mode:
swtich off phone ---> press and HOLD the home button ---> press the power button to switch on the phone.
Try plugging it into your computer, see whether it detects the phone.
Try another USB port if it fails or try on another PC.

I tried on both the iPhone, 1 is in DFU mode another is in blackscreen (cmd) mode..

Virus!!

Hmm... weird, just keep trying to get them detected when in DFU and restore it.
Can you check in your Task Manager whether Apple Mobile Device & iPod service is running ?
Possible ?
iPhone virus that spreads ?

met that BSD root : md0 , major 2, minor 0 twice.. it may still can be fixed may not.

if this problem occurred before attempting to unlock, then you can follow this link's guide.

Under task manager, the driver is not working and i cant upgrade it either

You can start them both under Control Panel ---> Administrative Tools ---> Services

I restarted the apple mobile device but still the same
