Q: Iphone stuck in recovery mode - wont turn on

Hi,

I was trying to restore my old iphone using itunes as i cant recall my passcode.

Accidentally unplugged the phone out when it was downloading the update.

Now my phone cant be switched on, even with hard reset, it shows only the apple logo and turns black again.

I tried connecting back to itunes to do restore but the error message keeps appearing.

Can anyone assist on this? Really need the phone as im flying overseas in two days time.

Thank you!!
