I suggested both Lightfoot and Gentarkin and will happily help anyone who needs someone to perform the reflash down-under. My jig arrived yesterday and there's some good news. First of all the reflash process is dead simple. Once you have removed the card from the chassis, it takes less than 60 seconds to flash the card and verify it's working correctly.

The next peice of good news is that once you've done this, your B1 and B2 miners will be transformed into Batch 3 miners. The hardware is all the same according to Chloe, it's just the firmware and software that is different. To prove this, after the firmware upgrade I'm now running the Batch 3 2.0.2beta software.

And finally the news you've all been waiting for. It fixes the restarts !! Here's a link to some photos of the jig and the process along with a  screenshot of two of them mining away happily on ProHashing over 8 hours after I restarted them (see the time elapsed since first share submitted).

Inno have kept their word and sorted this so I'm one happy+releived camper right now.  
I've had 6 weeks of sleepless nights but can now relax a bit.

Just stay patient and I think Inno will make everything right for all B1 and B2 owners.
