I downloaded "hashra-firmwareimg-v6" today as I couldnt get any other IMG files running with these GS
Straight in, away we go and theyre sitting stable at 362Mhs scrypt only mode.
I -did- do an update as soon as I logged into it by calling the IP from my laptop, and its stable, 4 hours later...
** just trying to find out how to add backup pools **
I don't think that version has failover yet. You can download the latest img from the hashra support page. the MINI and ATLANTIS are versions for your gridseeds I think. ATLANTIS is scrypt only
