Hacking Question Downgrade from 10.0.1 to 9.2

Natillax · May 22, 2020

Hi!
I always used autorcm and sxos cfw (never ofw option) and I would like to ask you if I can downgrade from 10.0.1 to 9.2 due to the errors of the cfw in that version or if I can't do it due to the efuses burnt.
Before writing this thread I checked other threads and I didn't find any answer.

Thanks.

Yes, you can downgrade. However, there are a few things to keep in mind:

If you don't have a complete NAND backup from before 10.0.x, you will likely have to reinitialize the Switch when doing the downgrade, meaning you will lose all save data and previously installed games.
If you burned your fuses, then downgrading will make it so you will be unable to boot your Switch without a custom bootloader (fusee-primary, Hekate, etc.). In other words, you will effectively be required to use AutoRCM if you downgrade to a system version that expects a lower fuse count than you have.

That all said, what errors are you receiving? I don't know about buggy SX OS, but Atmosphere works just fine with 10.0.x. I find it unlikely that you have any real need to downgrade. If you haven't already done so, remove your CFW from your SD card and redownload it.

I've used SX OS on every firmware up to the latest (10.0.2) without a single issue.

Did you downloaded the latest SX OS? The latest works perfect with 10.0.2

Sadly SXOS doesnt work perfect on 10.0.2 yet.
Certain games under certain conditions will 100% reproduce a system crash

See for example the sx forums: https://team-xecuter.com/community/forums/sx-os-beta-product-support.101/

EDIT: I heard that a fixed version is on the way and it is in testing currently

I am using SX OS with an emunand, which I had updated to 10.0.1 but I was facing many problems with the SX OS 2.9.5, such as the error 2168-0002 on many games. I downgraded the emunand to 9.2.0 by installing the 9.2.0 firmware through choidujournx and everything works perfectly. No need for factory reset or re-initialization of the emunand.
