Due to the huge amount of redundant topics in the mining support board , also the “words” used in describing the issues can be very hard to search for, many members have topics with titles such as “help needed” and then they post an image showing their problem, these topics are almost impossible to be found, therefore I wanted to make a sort of collection for most common issues in one thread.
I could also use some help, if you think that there are more topics that need to be added, please post away so that i can add them, also if you have any suggestions for better tittles to these topics feel free to suggest.
Before you post anything asking for help, please ensure that you have done the following:
1- Reboot the miner ( many issues can be solved by simply rebooting the miner)
2- Flush a different firmware
3- Reset the miner, you have to try these 3 methods >

5- Try a different PSU
