I had tested the 0930 firmware working perfect in my Z1，the temperature bug had been fixed in this version. this version can auto detect Z1 & Z1+,set 900 for Z1 925 for Z1+.
But when you export JSON file，the default frequency is 925 for Z1，I think it is a new bug in this version.
hey glfrank
can you or someone else tell me how you updated the firmware?
i downloadet the file (z1_static_100_09_30_release_overclocking.img - 4GB) and then i used a Image-To-USB-Tool to burn it on the usb stick.
But my miner dosen't boot with this firmware.
At least i was smart enough not to use the original usb stick.
So i could just switch the sticks ad my miner works again.
But i really would like to know how i can do it...thx.
