ok i see, so as long as you keep the switch in RCM you can boot into Hekate and perform the backup with out any risk to the console.
that device seems similar to the ch341a programmer for bios chips, at stock it provides 3.3v to the chip but you need a 1.8v adapter for any lower voltage chips.
yes i see what your saying, the 1.8v on this board could be fragile
thanks again for the help, ill make notes of this for reference
