My Iphone 4 suddenly blackout and restart by itself. After that it reach the restore screen. Tried to do restore but it come out Error (9). Anyone can help?

I tried to restore in normal mode and DFU mode, both of it still give me error (9).

I tried using other cable and computer but it still the same.

Anyone out there having the same issue that can share?

Is this a hardware or software issue? My warranty already over and have to solve this problem by myself.

Please help.

iPhone 4, iOS 5.0.1

Did you check your security software settings?

Error 9: This error occurs when the device unexpectedly drops off the USB bus and communication stops. This can occur if the device is manually disconnected during the restore process. This issue can be resolved by performing USB isolation troubleshooting, using a different USB dock-connector cable, trying another USB port, restoring on another computer, or by eliminating conflicts from third-party security software.

I have not really check on the security setting. Just wonder why previous i don't have such issue while syncing, only recently the problem appear.

Will try to check on the setting, hopefully it will solve my problem.

I saw other people discussion about this as well, some people still have the same problem after they diable to anti virus or other software.
