Bitmain Antminer S19j (90Th) firmware
Official firmware versions matched to the exact ASIC model or manufacturer family. Local copies include SHA-256 checksums.
Firmware is hardware-specific. Match the exact model and control-board revision, back up settings, use stable power, test one miner first, and never interrupt an upgrade. A wrong image can make the controller unbootable.
