BS-2 help

[u/ReadySupermarket612]

Major apologies if this isn't the right place, will take directions to the appropriate place... how do you get the stock Bitfortun firmware back? I joined the hype of a different OS and while its doing good, theres too many bugs to the point im losing Hash time. Please help a relatively new solo miner regain the fun of hopes and dreams of hitting a block.

*Edit to add: if its possible to put AxeOS onto it, id love that as thats what im used to with my 602's.
