I've been following the instructions in this thread:

Everything seems to work as it should until the actual Phone Update screen pops up.

It starts going through the upgrade process, but then keeps telling me that there's a problem between the cell phone and PC. It wants me to reset my phone and start again. But it does the same error every time.

Here's my log from the updater:

Can someone please assist me with this? I'm brand new at trying this sort of thing. I've been reading through various threads but can't seem to figure out how to fix this problem.

One person commented on setting the phone to "download mode":

"Try connecting phone in download mode

Press Vol Down and Connect Cable or Press Vol Up and Connect Cable"

I've been trying that, but it doesn't seem to do anything on my phone.

Any help would be greatly appreciated. Thank you.
