Hacking Question Switch wont power on after downgrade & Sleepmode

[Neo127]

Edit:
Switch now works again after replugging the battery

Downgraded my switch back to 5.1 (Loaded old backup).
Then i played some Games at lunch break at work, when my console fall in sleep mode.
It had about 70 % power left at that point and no game was running.
3 Hours later at Home I tried pressing the power button for 15 sec to turn it off and go back into rcm (no autorcm installed) but my switch wont turn back on.
My PC doesn't list it in the device manager and if I hook it up to the power, no loading icon appears.
And normal power on doesn't do something either. I am realy lost now ._.

Maybe usefull:
My right joycon still displayed 2 green light from using it as a second player.
But as soon as i clicked on it the light went out

you probably burned fuses so your switch fails the fuse count check and wont turn on with that fw anymore, it should be able to boot to RCM tho so you should keep trying that and boot some cfw to update back to the fw you downgraded from if you want normal boot and sleep mode to work normally again

HI anakinvm
The thing is, that even after 2 Hours on power. It still wouldnt show up in Windows TegraRCMGui. It yust says: Waiting for device in RCM mode

btw, any reason why you downgraded the fw in the first place?

I Have 1 Backup for OFW and 1 for CFW Stuff.
I switch them very very rarely. Like only 2 times atm

Doubt your getting into RCM, thats what it sounds like to me. And fuses are burnt...

Worked 20 Hours ago and didnt moved to joycon (tinfoil)

OK well tinfoil mashed into the joycon rail is probably one of the worst (and unreliable) ways possible to get into RCM. Not to mention more likely to cause more serious shorts.

If you for whatever reason you can't get a proper jig, I'd recommend THIS METHOD.

And since all your fuses are burnt, you cant go back 5.1.0 unless you load it via hekate (which disables fuse checks on load). However you'll still have problems with, sleep mode, as another fuse check happens when the system wakes.

Also put the damn thing in AutoRCM, at least until you can spare a dollar for a proper jig! lol

Tried 2 jigs, but port 1(i think) and 10 didnt worked and there are rarly any with pin 9/10.
BTW repluged the battery in the switch. Now everything works again. Maybe the switch just froze and the fan didnt move(?)
i dont car. It just works now.
Thanks for the community for trying to help me.
love you guys <3
