Hacking Discussion Messed up my Switch - maybe fully bricked after fw update

LapCheong · Jun 18, 2020

Now i doubt his switch is even in RCM mode, because if you have done nothing on your PC. The drivers should be untouched and be a working condition. Your PC is fixed variable, your switch is the one not in the condition to receive a payload.

Maybe you try holding power button and force shutdown your switch, then click the power button once. This will always put you in RCM unless your battery is dead or usb c port is damage.

Whatever you do to your switch for the sake of common sense, back it up. Not only your motive of updating to firmware 10 is a good one. You totally negligent that you have to install sigpatches, just go read it up and save others some time help you.

Thank you for the long answer!

as long as you did not corrupt ya prodinfo/prodinfoF and you can get ya biskeys of the switch..

How can i proof if i have corrupted the prodinfo?

Canna said:
.. but I won't kick ya ass about it you learned ya lesson.

No you dont have to, i already did that. Thats gonna hurt for a long time i guess. Lesson learned!

Canna said:
I want to know what is your rcm method ? How do you put your switch into rcm mode.?

I bought a RCM Jig and used that to install Kosmos. Since then i didn't use it. AutoRCM was disabled (as i know) and i used Tegra to inject Hekate and start the CFW. I had the Switch on Stand by, so i didnt had to do that so often, only when the Battery was empty.

Canna said:
best charge method is direct from the official Nintendo charger.

I was only using the official Nintendo charger to charge the Switch. And the USB C Cable of my Samsung Smartphone to connect it my computer.

Canna said:
If you look at the screen when you turn on the switch it should lightly glow around the edges of the screen. Watch for screen changes when you turn it on, best seen in darkness ofcourse.
If it does light up its not the battery. as you have power.

I went to the darkest spot and also threw a blanket over me to check. I had the Switch for one hour charging and connected it with the Charger while testing, but no light... nothing happened, completely dark.

Canna said:
Def check the cable can be used with another usbc device.
Shorter cables the better. to make sure the cable is good.

I tried all the Cables i had here, no one worked.

Canna said:
Also, try tegra gui and cable on another laptop or pc.
You only need to click the install driver once and follow the prompts, best run tegra as administrator.

Already done, didnt work.

Canna said:
Check your rcm method, try another rcm method.
Don't be using that tinfoil shit ffs.

Which method should i use?
I just used tinfoil to install the .xci, before that i was just using Goldleaf

Canna said:
Not all usbc cables are data cables some just charge, Make sure you have a decent one.

Just bought one, will be delivered tommorow.

Canna said:
One last thing make sure there no shit in your port bit of bum fluff or Cheeto dust etc

Thats the first thing i checked, its all clean.

And again, thank you very much for helping me.

.

Simple, you burnt your fuses thats why even horizon cannot boot. Your pc didnt detect because your switch is not even in rcm.

Remove any cable
Plug the jig
hold power for 10sec
PRESS AND HOLD VOLUME UP
TAP POWER
Plug in cable
watch tegraRCM to detect

easy

mangopeachcat · Jun 18, 2020

so.. um. i've done this before. op might need to re-jig to get rcm back. have you tried it again at all since this? not sure if i reformatted to a different partition like op did during the whole situation. not sure if that affects anything, either.

if they can get rcm back, someone will need to make op some blank boot files for 1.0.0 firmware

then they can start it up and reapply the proper update

from what I understand, downgrading messes with fuses or something and then the boot sectors and os start fisty cuffs
matching boot and hos fw means everyone's happy

i wish you luck on getting rcm detected on tegra and help on the blank boots. sorry if it ends up failing

I tried to shut it down for many times by now, i've held the Power Button for 10sec, for 30sec, even for one Minute. Nothing changed.
First i didnt knew about any sigpatches, after upgrading und the first errors i read in the forum, that i need the sigpatches and downloaded them. But i guess those were the wrong one and way too late...

Tried that, but no reaction

Edit:
I'm still working without the SD Card unless someone tells me to use it.

Edit#2:
What the F... its showing me RCM OK. My Switch is plugged in.. what should i do now? im so excited

LapCheong · Jun 18, 2020

Insert SD card and push hekate with a fresh SD card WITH ONLY ATMOSPHERE then backup your saves

Most of the time it is just user error, as you can see here

Your main goal is running the latest firmware with Atmosphere

After that read a guide on what to do.....

My job is done here

Let's start from the beginning. What did you select in choidujournx? Did you leave everything on default?

That does not answer my question whatsoever, but at least you are booting somewhere.

Ok. So you installed autorcm and did not format the switch.
The formating part might be a pretty bad thing.
And did you select exfat?

Also, did you already try booting into the maintenance mode?

I tried everything but nothing worked. I formated the SD Card to Fat32 and exFat again. And as i said i could finally load into Hekate and i am following the guide now. I am at emuMMC now.

When i finished the guide i linked above... can i update my firmware from 1.0.0 directly to 9.2 from darthsternie?

You can provably update no problem. But in that case, update straight to 10.0.4.
But creating emummc won't do a thing, as you will just create a copy of your current unbootable system.
And were you able to boot to the maintenance mode or not?

Epsylus · Jun 18, 2020

what do you mean with maintenance mode?
i could run Hekate, nothing else. No CFW no Stock, nothing. Just Hekate.

Ok, what should i do instead?
I've downloaded Atmosphere and Hekate

Boot to hekate and select boot to stock. And as soon as you can, hold both volume up and down (preferably before you even select the boot option).
If you are lucky, it will boot to maintenance mode where you can format the switch or update it from there.

P.S: pretry much any boot option will do, just hold the volume up and down while booting from hekate.

ok, what will that do with the Switch? Will i have fw 8.0.2 again? Will it clear everything? And what will i have to do after that?

I would say that it's kinda obvious. From there, you can either format (higly recomended), or update (to the latest fw).
But you have to be able to boot into it first.

Tried it and it booted.
I can select now between reset without deleting and factory reset.

Your best bet is factory reset (but you'd lose everything). By reset, you mean what? (I don't have a switch with me right now)
Reset like factory reset but without deleting your data?

But, as always, even though your switch won't boot, do a backup. It can always get wors!

I did the factory reset
what are the next steps?
