Hacking Black Screen after updating OFW on a SX Core Switch

[luisdav]

Hi, I just updated the OFW on my Switch but I got a black screen now. I have read on several posts that there was any problem with updating the OFW on a Switch with Sx Core installed. I updated the OFW after booting the OFW using a dedicated SD card to play only th the OFW. My Switch is a Mariko, with SXOS 3.0.5 and previous firmware was 11.0.0. My intention was to update only the OFW to the latest, I think it is 12.0.0 or higher and keep my emuNand in the 11.0.0. But now I got a black screen after trying to boot either the CFW or OFW. Does anyone have a solution for this? Can I switch to Atmosphere in this situation?

Thank you.

Can't use SX OS on sysnand above 11.0.0, your option is Atmosphere.

So why is people saying it was possible? I updated the OFW without touching anything in the CFW or emuNand it should work...
The question is: I still can fix this? Either to keep the SXOS or switching to atmosphere? I can get into the SX screen, I just don't get the Nintendo logo, the switch just turn off.

SX OS is no longer getting support, you should switch over to Atmosphere while you are at it, there has been no official support since firmware 11.0.1 and above, I don't own a SX Core so I can't help you too much but you can check out this video for some reference.

Thank you! I'm digging into this. It seems that I have to wait for the latest version of Hekate to use Atmosphere, because there is support up to the 12.0.1 firmware. I got the 12.0.2....

True. I thought it was not released yet, but it was. Working on this.

You need sx 3.10 then load tx boot menu then sx core then genuine boot.

I read about the genuine boot option, not sure if it is gonna work plus it burn fuses.

You don't need to do a genuine boot. If you updated your sysnand past the firmware supported by SX OS, you can just chain load into Hekate from the SX OS bootloader, then boot into stock sysnand from Hekate.

Yes, I can boot into the original firmware or sysnand, but I can't see my games or back up my saves from there. They are only visible booting in emunand.

I'm confused. Why would you expect to see your (presumably, backup) games on sysnand? The point of having emunand is to only hack in emunand and to keep your sysnand clean.

yes yes, that's what I'm talking about. I only have access to sysnand, and can't do anything to play or rescue my saves in there. I need the access to emunand, which I don't have and I need.

after reading a lot of posts and trying a lot of possibilities it was not possible to read previously installed games and saves under SX. I decided to stay in Atmosphere, I lost my games and saves. Now installing everything from the beginning. The best recommendation for other users: Make back ups of your saves ( I use JKSV).

I think you gave up too early. If you follow this tutorial, you can extract your saves from emuMMC.
