hey man thank you very much for the help! appreciate it since i just try to figure out how to move on from here with my first antminer

does flashing those firmwares mess up my warranty?

The issue with the fan is weird.
The intake fan wasnt working and we replaced it with a new one - still didnt work. We then switched the new (still not working intake) fan cable with the old (still working exhaust fan)
--> the exhaust fan  still worked // intake still didnt work .. makes no sense to me

thanks guys. i might just have gotten a messed up miner from ebay. not sure.
I dont think i myself broke it by simply turning it on and off 3 times?! lol

<3 to everyone

edit: learned to use code tag
