how to slove 2002-4686 issue if you haven't clean rawnand backup
hey guys. i make a little experment recently. restore another switch's rawnand backup. please don't be laughing. i speaking chinglish.
after NS be brick. i only restore it by my switch's boot0/1,sys nand. not include "user" partition. strange things happened.
let's keep going
firstly. i select kosmos11.10.2 and inject hekate4.8.bin . backup my switch's boot0/1,rawnand,sys&user. (rawnand=sys+user)in RCM menu, also include biskey by biskeydump. then i copy these bakcup to my laptop's harddisk.
at the second step, i copied another switch's rawnand into microsd replaced mine. then restore it as normal. of course. my switch be brick.
but if i restore my switch's nand backup except user.bin. the console can power on but it stuck as follows picture, it shows error code 2002-4686. not only OFW but also CFW. restart or power off restore are also stucked again.
so i think does NS system have a verfied function with keys checking after bootloader? it was a chain keys-checking possibility. maybe it found the user partition's key is not belong to this switch. after that. i have tried to use gptrestore, memloader, hacdiskmount fix this issue. but it still doesn't work. my switch also happen blue screen, red screen, purple screen if i around break switch's gpt or some important files.
when i use hacdiskmount to decrypt user's partition by another switch's biskey 3, it just only allow to mount it, but not allowed to change the partition's key.
finally. i use gptrestore and my console's boot0/1&rawnand to restore my switch. eventally my switch works. can running ofw or cfw as usual.
i was curisously for one thing, why boot0/1&sys nand backup couldn't allow the OS working? does anyone know why? or if you restore another switch's rawnand. how to fix issue if you have only boot0/1&sys nand backup by yours.
