I got my sd-card adapter. Apparently its USB 3.0 but luckily 3.0 is backwards compatible all the way down to 1.1.
I flashed the image onto the adapter, stuck it in, booted it up and nothing. I go to the ip address and its still the old firmware.
From my understanding, it should have auto-installed after boot-up...
It could have flashed the firmware but just so happened that it is the same version, to confirm if it went through or not, you would check your pool settings (should go back to default settings) and the miner's ip settings (back to dhcp).
Try BraiinOS, it should boot from the sdcard without flashing to nand.
