[daxster40]

hi, running 8.1.0 cfw i was playing Retro arch and for some reason the switch crashed on the error screen then when i rebooted tried Rcm sent my payload nothing happens. just stays black screen. but i can ear all the sounds that windows makes when either plugging usb c cable in and when its in Rcm mode im confudsed can any one help pls.

 

[Budsixz]

are you using autorcm?

 

[daxster40]

no just Tegra to load payload, Budsixz.

Exfat?

 

[daxster40]

no fat32

 

[Paulsar99]

What cfw you're using?

 

[Budsixz]

no fat32

try holdingpower button for 30 sec so that the switch completely shuts down
then try to push payload again
If that doesnt work then it could be a corruption in the card so you can try to format the card and then use a fresh set of cfw files ( best to try this with a spare card if you have one)

 

[daxster40]

thanks for replying, ive put a fresh card in and powerd down and up lots of times just wont get past black screen

If possible do you have another microsd card you can test with? Max 16gb or such? I just wanna test so you can enter RCM.

 

[daxster40]

yes i have a spare sd card ,

 

[Paulsar99]

Weird that a retroarch crash would suddenly not make your system unable to boot back to cfw unless it's a sd card corruption. I hope this isn't a hardware issue like your sd reader failing.

wont even turn on in normal mode. but you can ear the noises windows makes.

only other thing i can mension is i updated to 9.0.0 a few days back.. then using ChoiDujourNX, i downgraded to 8.1.0 but it was working fine for 3 days before this happend yeserday

 

[Paulsar99]

Can you boot ofw without a sd card?

 

[daxster40]

no it wont boot in to offical firmware , even when sd card is removed

Did you hold Power button for over 12seconds like Budsixz said?

Try using a different sdcard, install the Kosmos package and try booting RCM.

yes for over 12 seconds

Since you downgraded I think that you dont have autorcm and have a fuse count mismatch

 

[daxster40]

is there any thing i can do so solve the problem?

I want to ask you a few things first -
1. What cfw were you using?
2. What is the current fw version of your switch?
3. Do you have nand and boot0&1 backup?
