I recently got my hands on a used Antminer E3. I found the firmware file hive_install_unsig_antminers.tar.gz but I’m unable to flash it with the ASIC web interface or BTC Tools. BTC tools says successful, but nothing happens. Through the Antminer interface, I just see a bunch of text and code pop up when I try and flash. Can someone please help me? Would really appreciate it.
