Hacking switch will no longer turn on with sx os

[jakkal]

and that's why nobody does AutoRCM, its not very safe....

this has nothing to do with autorcm
this has happened to my switch a number of times

please read

Ok :v

@jakkal I appreciate the help you offered OP but do not spread misinformation that the cause is not linked to AutoRCM. It has already been proven that a corrupted BCT reduces the charge rate of the Switch so this is very much an AutoRCM-related issue. The proof is below

So, Switch charges and does not charges in RCM. xD

The results (battery was 89%):


The switch can charge normally the battery, if the BCT is intact!
In RCM AND in hekate menu.
*BCT is the boot configuration table that autoRCM corrupts.

Tests showed that it was charging with the same current, as in Horison OS.
The current it was drawing with 89% battery, was 800mA - 1000mA, using Switch wall adapter. On PC, it was the max the hub could give.


------------------------------------


The switch cannot charge normally with a corrupt BCT (AutoRCM).
In hekate, it shows similar behavior (read below).
Extra emphasis on the "normally".

With autoRCM, basically a corrupt BCT, the switch behaves differently.
There are 2 behaviors that I saw when connecting to the switch wall charger:

• Common - It was draining 140-250mA.
• Common (in hekate) - 200mA - 400mA
  
• Rare (normally if you connect charger after powering off from HOS) - Drain of alternating 250mA and 1000mA, with surges of 2.5A.

------------------------------------

Summary - facts:

1. Switch can charge completely normally in RCM or Hekate with a BCT intact
   • The percent % in Horizon OS, after a RCM charge, is not fake.
2. Switch does not charge normally with AutoRCM, a.k.a corrupt BCT.
   1. Either it charges very slowly or sometimes with a broken slow/fast/slow/fast charge pattern:
   2. Or this behavior is current taken from the USB controller or the BPMP (Nvidia's Boot and Power management processor)
   • In AutoRCM, the Charge IC probably can't update the battery calibration file and could make the percent fake.

I don't know for behavior .3 what really happens and what Switch does. This can be easily examined, by connecting a current multimeter between battery and switch and check the readings.

AutoRCM is relatively safe. That being said, if the battery dies with AutoRCM installed, you only have two ways to charge it back to 100%:

1. Boot into Horizon OS and slowly charge it while it's connected to the computer. After it charges enough to boot the home menu, you can plug it into a wall charger and charge much faster. This method is likely to take a very long time to get into the home menu.
2. Boot a payload that allows you to remove AutoRCM, and then plug the Switch into a wall charger. This is much faster.

So I doing this....

Go to book menu by hold vol+ then turn on.
Remove joysticks
Power off
Put in charge
Wait for 5 minutes
Payload again

Now you see Nintendo logo.

It's how I can turn it on. I think problem here is joysticks while them in.

Same thing happened to me.
Solution is very easy.

Download tegrarcm gui portable, sx os (boot.dat) and sx loader (payload.bin).

Put your switch to rcm mode (i guess yours is already in rcm mode)

Connect your switch to a pc and let it to be charged by the usb slot of the pc for likely 15-20 minutes.

Start tegrarcm gui program and send the payload to switch.

This has worked for me. Once it is booted to sx os, do not disconnect let it be charged a little more.

And dont forget. Never let the battery down while autorcm is enabled.

After that i turned off autorcm. I just put my switch on sleep mode instead of powering it off.
