have a switch here which gave 2002-4153 while using games. replaced the gamecard slot = same. installed an sxcore as i suspected a nandcorruption. backed the nand up, followed this tutorial to rebuild emmc and got a black screen. wrote back nanddump = blackscreen. wrote nanddump to another emmc = blackscreen. so im trying to rebuild an nand with original prod.keys in hope that the prod.keys are fine. im following this tutorial. im at step 4 and step 4 driving me nuts. first of all why would the auther say "
In the command prompt, type “ChoiDujour.exe \-\-keyset=keys.txt fw” without quotes" if this is clearly NOT what you supposed to enter. the correct prompt is:"ChoiDujour.exe --keyset=keys.txt fw". anyways i got past that and encountered the next error:

the value isnt x. i just censored it. after a bit of googling i encountered an advice to remove the keys above from the keys.file.

after that i encountered the next error:hateit:

Correct me if I am wrong, but Choi on Marikos was a big nono that would lead to bricks.
Anyway try following this tutorial https://gbatemp.net/threads/guide-fix-switch-with-bricked-emmc-without-working-rawnand.612011/

The parts in the video where TegraRCM is used you will boot with the chip to hekate.
For that you'd need SX Gear's boot.dat and ini if you don't already, put them on your SD root and edit the ini so it points to the hekate payload.
Also make sure to look If there are newer versions available than the one the person in the video uses.

Edit: this was just recommended as similar thread by GBAtemp itself lol
https://gbatemp.net/threads/guide-nand-rebuilding-for-no-backup-broken-emmc.593995/
Here you also would have to look for newer versions than the ones the guide uses.
