You need JTAG

what hardware is needed to do this

Any JTAG debugger, i use J-Link EDU https://www.segger.com/products/debug-p ... -link-edu/

Can i use mmx_fs0 to recover or i need to make a clone of another MMX?

mmx_fs0 is enough.
After device founding via JTAG you also need cut off BCT file from dump mmx_fs0 in 0 to 17EF adresses, then load this BCT file to MIB with help of TegraRCM https://github.com/NVIDIA/tegrarcm . It work via USB.
