I tried to update my Whatsminer M21S firmware from the site but having no luck. My current version is 20210322.22.REL. The WhatsMinerTool says it’s successful after flashing but nothing changes. If anyone has ideas or if there's a different firmware I could use, that’d be awesome. Also, any tips on how to SSH into these machines?

The link you’re using is dead, dude. Not sure if your firmware is right. The latest one listed is Whatsminer-M2x-all-20220511.19.bin, and it says if your miner's firmware is older than 2021, you should upgrade after swapping the SD card.

Check the date of this thread. It’s pretty old, so the link is probably outdated. You can find their newer files at this new link. And you don’t even need an SD card for that.bin, just use the WhatsMinerTool or flash it directly from the browser.
