@bitmaxz every time I try to flash via website it says incorrect file. will it be different if I use sd card?
It will be incorrect file if you are trying to flash SD card image through browser.
You need SD card and put all extracted file to SD card. Follow the guide from the link that I posted above.
Or if your miner control board is c5 then you wont be able to flash it through SD card. Use the firmware with extension tar.gz that support c5 controller and upgrade it through browser.
