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.

my best at PH has been about 48-72hrs

I was asked by Dominique from Innosilicon to share my experience.

I have 3rd batch miners, were very unstable with original v2.0.1

After I got v2.0.2 from them, it seems relatively stable on mono-coin pool (f2pool)

Miners tend to die (completely disappear) on switching pools - work for ~12 h on prohashing, then I have to reboot as they disappear from network.

Probably overheating, but it is hard to say - I can not watch then all the time.

If somebody managed to get them stable on prohashing - could you please share settings?

I will probably try them on nicehash - original firmware would not work there at all, did not try new one.

Will watch this thread closely
