Hacking Question After restoring rawnand, boot0 & boot1, Switch didn't turn on, no charging, no payload, nothing

[mYemc]

Hello folks,

I am new at the switch scene and with my newcomer knowledge I could not find a similar thread for this question.

I backup my system with hekate and also restore it with hekate. After the restoring process I turned off my console. Now I can not do anything with it. Please can you help me with that problem? I do not want to have a brick for my table…

Thank you guys

Is the firmware version of your backup the same as the one before you restored the backup? Have you updated the firmware of your switch after you made the backup?

 

[mYemc]

No. Updatet to 6.2 and wanted to go back to my old backup 2.1.

 

[pLaYeR^^]

Did you update to 6.2.0 without burning fuses?

 

[Paulsar99]

Did you update 6.2 via switch system update? You're pretty much screwed if you did that.

 

[Dust2dust]

How did you update to 6.2? Did you burn fuses?
Oops, ninja'd !

 

[mYemc]

I do not know what you mean with burning fuses (now I read parallel what it is). So maybe yes! I do it without burning fuses.

You burnt your fuse if you updated via system update instead of ChoidujourNX.

I did it with system per accident. (to slow for DNS calibration).

Thank you. I did not use ChoidujourNX.

Can you explain how exactly you have updated your switch? Can you launch hekate and check under "Console info -> Print fuse info" how many fuses on your console are burnt?

Boot into CFW and update your firmware again, your fuse count doesn't match that why it doesn't boot on OFW if that is what you are trying to do.

You can't downgrade once you updated via switch system update. You pretty much bricked your switch. If you have a back up 6.2 rawnand and boot you might be able to fix it.

And jeez what's even the point going back to 2.1?

 

[mYemc]

I updated the my switch with the update option in the settings. I can not launch hekate. The console did not react to any input.

 

[Dust2dust]

A question that is worth asking... did you make a NAND backup of 6.2 also, before downgrading?

 

[mYemc]

No I only make a backup of my first firmware.

 

[Kafluke]

You cant simply downgrade unless you upgraded without burning fuses then used autorcm to prevent the burning of fuses.

I dont know why so many people get this wrong. Just because you have an older backup doesnt mean you can simply downgrade

(Yes, yes I know you can use custom boot loaders to launch older OFWs with burnt fuses but since there is no reason to do this I leave it off my original statement)

Do you know if you were in CFW while you performed the system update?

After rethinking I am a total retard and it is logical ...

I am very sorry. I do not know, because I restarted my console so many times. My bad, sorry.

So I am fucked, right?

So putting your switch into RCM and injecting a payload doesn't work? It should, normally, unless I'm missing something obvious. Then, in theory, you would boot your 2.1 with hekate, update again to 6.2, and you're back to normal.

I totally agree with you, but my console does not react to any input. (power + volume up etc.).
