Tinfoil bricked my switch?

[auggiethecat]

I installed tinfoil on my switch with the firmware downgraded to 17.0.1 without knowing anything about the bans. It asked me to update and i did carelessly. Now when I open sysnand, it shows the first Deepsea logo, but not the atmosphere logo. Just a near-black but still on screen. How did this happen, and how can I fix it?
Atmosphere 1.7.1
HekateCTCaer 6.2.1

You got any NAND backup?

 

[auggiethecat]

Yeah. Do I need it?

Yeah. Do I need it?

In your case you got an unbootable sysnand, result of you downgrading the firmware. Do you know what firmware is that NAND backup

 

[auggiethecat]

I don't know. Maybe 18.0.0?

You can try to restore the backup you have see if it boot, you need the boot0/boot1 and the rawnand.

Your console is not bricked, do not panic. I had the same problem. You've started Tinfoil and clicked 'UPDATE request' and console has gone to the RCM chain loop.
All You need to do is to break the chain erasing chain protocol on Your SD Card root - it should be *.ini file ... and do not forget to erease whole Tinfoil folder
Or the simple way ... Erease everything from Your SD-Card beside ''Nintendo'' folder, You will keep Ur some saves and installed data and voile'a ... Your system will stand again with Your common injection file (ATM1.7.x) or whatever You used before.

I will try that when I get a chance but I have a strong suspicion that wont work. Thanks for you help though!
