There is a way to bypass "Cannot Find Signature", maybe you can look at this:
https://www.zeusbtc.com/articles/asic-miner-troubleshooting/3011-how-to-bypass-can-t-find-signature-when-updating-antminer-firmware
But, this operation has certain risks. Generally not recommended.

That would work if the miner SSH is not disabled but most of the 2018 to 2019 firmware is ssh disabled and locked firmware.

Your only last hope is to flash it through an SD card and nothing else.
