Hacking Guys. Please help me with unbrick my switch

[iCRON]

My 2nd thread about this... I didn't want to do it, but my first post on the subject doesn't seem to interest anyone. I really need an experienced person who is familiar with the PC downgrade for the switch. I have already gone through the scrap 10 times with all FWs from 4.X to 6.1.0 to untangle my bricked switch but unfortunately to no avail. Since I don't feel like getting a new one because the hackable ones are ALWAYS somehow unbrickable. I would like one of the experiences with the PC downgrade to support me a little. Here are some of the current data from my console:

Firmware 4.1.0

eFuses are on 5

How it bricks: after a NAND Restore with Hekate (Backup exist in 14 Parts)

What happens:
StockFW: blackscreen without anything

Atmosphère: a fast little „atmosphère“ splash and then blackscreen with screen backlight https://drive.google.com/file/d/1QVk1etaLsBLUdIg95l-0YX2AwPBtEApk/view?usp=sharing

Hekate: Pkg2 decryption Error/ always the „Kosmos“ Splashscreen

What i tryed:
-Redoing NAND + Boot0/1 Restore with Hekate
-PC Downgrade with all FWs there was supported with Choidujour

Please, please I'm slowly despairing but I hope there is still hope for a safe unbrick chance

Thx but I don‘t hangs on 3rd screen or on the „black atmosphere symbol“. I hangs on the first blue atmosphere screen there showing here https://drive.google.com/file/d/1QVk1etaLsBLUdIg95l-0YX2AwPBtEApk/view?usp=sharing

Not sure there is much anyone can do if your backup doesn't work. May or may not be corrupted, meaning important files on nand might be corrupted now too.

Unless it's something simple like not having deleted a custom theme before changing firmwares (delete "0100000000001000" folder in atmosphere/contents and/or atmosphere/titles)

You tried a clean atmosphere install or another sd card, also try booting with fusee-primary.

Ok then I haven‘t any chance to unbrick because I don‘t used custom themes. If only I could find out exactly what is wrong with this backup, how it broke my switch ... I cannot disassemble it in that state and there is a method like the ctrtranzfer on the 3DS so that I could try a 4.1 NAND image from the network it doesn't ... And everyone says that with hackable switches it is "impossible" to completely brick them so that they can no longer be unbricked ... but that was once again a complete rubbish from the developers out there ... hach

I have a 32GB SD Card in Fat32. I updated Atmosphere and all other to the latest version. The SD Card work fine but I can‘t boot in any CFW or StockFW

Have you tried going through the switchs official recovery mode?

1. Ensure the console is powered off.
   • If the console does not respond, hold down the POWER Button for twelve seconds to force it to shut down.
2. With the console powered off, hold down the volume up and volume down buttons, then press the POWER Button to turn the console on.
   • Be sure to keep pressing down the volume buttons until the recovery mode menu is displayed.

In case this works at all, you'll burn all your fuses and whatnot, but that's still better than a broken system

Won‘t work because this brick are in the boot process and don‘t have access to the Recovery Mode. The Recovery Mode works only in Softbricks example if a Error screen pop up after the „Nintendo Switch“-Logo
