    Suggestion
    Is there a way to stop hardware checks for Charging IC M92T36 & Bluetooth NIC IC BCM4356 on NX boot ?

    I noticed when this two IC's has a hardware issue (maybe cold solder joint) the Switch will stuck on "Switch" boot logo. Same with "Orange Screen" -> Issue BCM4356.

    But very intressting is on this thing and realize with BCM4356. If the battery is lower as 10% (power save mode) the Switch will continues loading and didn't stuck.

    Therefore the question to turn HW checks off and I know at the end (or not?) is the IC damaged but with this you can boot and maybe retrieve datas.

    Note: If you're NSW will not come back from standby (0xE401 Invalid handle) it will also help with low <10% battery power to work back again! Try it...

    This would be pretty helpful for diagnosing broken Switches...

    An RCM payload with some low level diagnostics would be great

    Wish there was a patch to disable these too. I have perfectly working switch, except the BCM keeps it from booting Horizon. Linux works though ¯\_(ツ)_/¯.

    Tried multiple times, not sure what's going on so I am making a thread about it.

    Yeah it's definitely more involved. :lol: New chips don't work so you need to reball, with the proper stencil and the tiny solder balls are a pain in the butt. But it's doable with some practice :creep:
