hello ( iam french ) ,
i have an nintendo Switch HAC-CPU-20
and the console make nothing
i have fond un small component namd ( SD ) burn
i have change it and no resolved the problem
i test all component with multimeter no short cicuit
i try new swcreen new battery , and nothing happen
when i connect to pc the PC see the nintendo switch and tegraRCM say : RCM is connected
iam lost , do you have idea ?
thanks you
Remi
No idea of this probleme ? Thanks d’avance
Can you inject the hetake payload?
Yes but nothing happen , I never jailbreak this console et never actived the auto RCM
That it’s weird
When you say nothing happens,do you not get any output on the PC?
if you’re hitting RCM mode with the NAND plugged in and not using a jig, have not initiated auto RCM, would that not indicate a potential issue with the NAND?
just spitballing.
Tegra RCM say : payload are injected
You think nand have probleme ?
I have try to connect switch to tegra RCM without nand plugged, and I get same thing , I have try to swamp with other nand , same thing , maybe I need to use jig ? And retry ? Thanks
It isn’t a good idea to swap nands!
If the firmware on the second nand is higher, it will burn the firmware fuses on startup and you will be not able to access the original nand.
Without a nand a Switch goes directly into rcm mode.
With a nand installed you have to use a jig and the “Volume +” and “On/Off” button combination to get into rcm mode.
^^ this is what I was referring to. If your NAND was plugged in, and you didnt start with a jig, AND you’re sure you dont have auto RCM enabled, my next steps would be to inspect the NAND and its circuit to see if anything unusual pops up.

you can use the above site to see if your switch is patched or not, If its not patched you can create a proper hekate payload and inject that. If hekate is able to be injected there are some nice tools built into the software that could potentially provide more information on what the fault may be. I do believe that there are some earlier SN’s from the HAC-CPU-20 revision which are unpatched and exploitable
Y’a she is unpached but I never jailbreak it with hekate , I need make jig by myself and retry to that abs I need to control with my multimeter the nand thanks
If back cover and shield already been disassembled, simply detach the EMMC module from connector and turn on device would force it into RCM mode, then reconnect back the EMMC before sending payload.
