Hacking Switch won't boot up

[Gabri9292]

hi guys,i have a problem:

i've downgraded my switch from 5.2.0 to 1.0.0 and now it gives me the error code: 2002-4315
I don't have any nand backup

Why did you downgrade to 1.0.0? If you're on 6.2.0 or lower, there's no reason to downgrade right now.

In addition, if your fuses were blown, it's impossible to launch 1.0.0 without Hekate or another bootloader. Can you boot your system using CFW?

 

[Gabri9292]

no i can't

First off you cant just downgrade unless you first took a nand backup while it was on 1.0.0 and then upgraded with choidejour preventing fuse burn and expect it to just work on cold boot. That's not how it works. Secondly why would you ever try to do anything without a nand backup?

Your gonna have to boot to RCM and use the PC version of Choi to fix it but I dont even know if it supports 1.0.0

Try to see if you can boot to recovery. Hold volume up and down while booting and tell us what it does

1)where i can download the pc version of choidoujuor

2)i can't boot to recovery mode

Why did you downgraded to 1.0 to start with, there's no reason to do that
and also, why are you doing things without a nand backup

 

[grepoman]

You have to tell us why you downgraded to 1.0 before we are able to help you. This is an essential information.

You can always boot to RCM. It's a flaw in the tegra chip. If you cant boot to RCM then you are doing something wrong.

This is a troll post... this is impossible you literally can’t downgrade without a nand please stop wasting people’s time...

I'm not sure where you got that information from but its completely plausible to downgrade without a NAND backup. Fusee Gelee allows us to bypass the fuse check due to it being a coldboot exploit so we can run any firmware we want. This is useful for situations where CFW don't support higher firmwares. You can read more in this guide.

You still have to have the firmware and since it’s 1.0 it has to be a nand backup

Firmware is as easy to find as game backups. As for NAND, no you still don't need it. I downgraded to 1.0 to prove a point and it is indeed possible.

i've resolved with the pc version of choidujour

xbins has NX-1.0.0.zip, it would only be useful for developers to do testing. I may be wrong but I have a vague memory that there were two slightly different versions of 1.0, what they shipped on consoles and some update found on a game or something.
