Hacking Can't boot my switch

[SooMi22]

Hello

I was running on 10.2.0 Atmosphere 0.14.4 and everything was fine, and after I updated to 11.0.0 Atmosphere 0.16.0 I couldn't start my games anymore, I didn't know what's the problem but I tried to downgrade to 10.2.0 using ChoiDujourNX (first time trying to downgrade) but after I've done everything and restarted my switch, I couldn't boot it to stock firmware (no Nintendo logo no anything, just a black screen) I tried to enter RCM and used hekate to run into Atmosphere, but I got an error, so I tried to update to 11.0.1 manually but when I tried to convert the firmware files I got this:

Using source firmware files from folder fw
Found 0 meta and 0 data NCAs in C:\Users\Admin\Desktop\???? ????\ChoiDujour\fw
System version NCA not found!

I don't know what to do now, can anyone help me please? or did I brick my switch?
and sorry for my English.

No NAND backup? What payload did you launch with? Fusee Primary or from Hekate to Fusee Secondary?

Sadly, no NAND Backup, I used Hekate to Fusee secondary

Try fusee primary, SD card format?

 

[SooMi22]

Try fusee primary, SD card format?

I tried fusee primary and this happened:

Nintendo logo > Nintendo switch logo > black screen with error code: 2002-2634.

I did format the SD card and still didn't work

2002-2634 I think it is cartridge slot firmware related, you got a cart inserted?

yes, should I remove it ?

 

[Hayato213]

yes, should I remove it ?

Yea, 11.0.1 updated the cartridge slot firmware so if you downgraded you can't use cart on lower firmware.

If you want to use the cartridge slot update back to 11.0.x, Atmosphere works fine on 11.0.1 with Fusee-Primary and patches from eXhumer github.

the link above shows you to chainload Atmosphere from Hekate if you need to.
