[Sony Xperia S, Acro S, Ion] James666PKR:
Connection error in flashtool

Hi guys, any help would be appreciated. I have been googling and searching the XDA forum for over a month now, changed my USB data cable twice (as i foun da post that said that could be the cause of the connection error), I have tried taking my phone off passcode lock, entering fastboot mode both manually, and in flashtool, but still cannot root my Xperia Ion LT28h (with stock over the air updated 4.1.2 OS). I am following the instructions to the tee (found elsewhere in the forum), but for some reason flashtool keeps FAILING.

Any advice would be really helpfull, as I always have a rooted phone, but since updating to jellybean, i've been unable to figure out how. Android-sdk is fully installed, iuncluding all the latest USB drivers etc...

I have included the complete log, showing the list of drivers installed/connected devices etc... for your information.
