Whatsminer M61 REL Firmware - 8 versions
REL is the previous firmware line for Whatsminer M61, support discontinued in 2025; REL2 is used for new releases. Use these 8 versions if your current firmware version ends with "REL" in Version Info (Whatsminer Tool) or in Status / Overview / Firmware Version (it appears at the very end after the last dot) in the miner's web interface. If your control-board model is h616, you can upgrade to REL2 via NeedUpgradeAgain firmware.
