ATTENTION: The firmware is suitable for all ASICs S9Dual.
If, when changing the BITMAIN firmware, you see the message: can not find signature, this means that your equipment has the 2019 BITMAIN firmware installed, in which the overwrite protection is installed, the 2018 firmware does not have this protection.
If you have BITMAIN June 2019 and earlier firmware installed, you can remove the protection using the "signature" file, if you have the firmware on July 31, 2019, you can remove the protection using the "signature_31july" file and then download our firmware or use the SD card (all files are posted on the site and instructions).
You can see the firmware version in the System - file system version section.
If during the flashing process via the SD card you see that 2 lamps (green and red) on the control board are on and do not blink, then most likely your control board is infected with the ANTBUILD virus, you must use a special image ANTBUILD_RECOVERY to block the virus.
