Hi, sorry for the late response, okay so i downloaded the release from this threat.
I downloaded the latest version of nxnandmanager ( that supports 18.0.0)
i dumped my keys with lockpick, made a backup of the nand (i did full and system only both dont work)
I load my keys in nxnandmanager, decrypt my prodinfo.bin, load system, and mount it as a drive. ( i can also see the files)
After that i open Switch dumper, select my sd drive , select the mounted system partition.
Set the decrypt and nsp output path.
I select Find SD card, it shows " sd key loaded.
i select load rsa kek it shows "RSA key extracted successfully from prodinfo.bin"
i select extract tickets it shows "done, 14 tickets dumped, Cannon extract personal tickets - Error extracted RSA keu not for this ticket"
than if i want to extract one of the games, it shows "Packing mars base [01006B1016BF800][v0].nsx failed."
but if i try the update, it not gives me a error.
I have a Switch oled, it checked my serial number and its also correct.
Not sure what i am doing wrong
