The entire process is done by downloading a file and flashing it via the firmware. There is no need to unzip the file or flash the Micro SD Card.
Go to https://kabo.om/firmware and click on “Bitmain Antminer X19”.
Determine whether your model has a Beagle Bone control board, or a Xilinx control board, and click on the appropriate link.
Click on the appropriate model to download firmware update under the section titled “Web Update Images.” There is no need to unzip the file.
Log in to miner and click on VNISH in the bottom left corner.
Upload the downloaded .tar file and click flash miner.
The Miner will reboot, and after a minute or two, the system will be updated. Enjoy the update.
