Hacking Question How to fix sx-os "boot.dat?" error...

[comput3rus3r]

UPDATE! 07/24/18 So turns out my switch had a weird factory defect with the sd card. It would work normally for all things official firmware related but payloads didn't have access to the sd card. The other symptom was that if i pressed down on the kickstand the switch would think the sd card was removed.
Check out this video.

This post explains the issue.

I sent it in to Nintendo for repair and they replaced the sd card reader. Now sx-os/hekate work fine.

From what i can tell from this experience is that there's no way for them to patch it once the switch leaves the factory line. The patch is applied during production not after.

just got my sx-pro and following the steps and i get this error every time with 4 differnt sd cards from sandisk 2 of 64gb, 128gb, 200gb. have tried fat32 and exfat and same result.

also added a 16gb sd to the test and same result.


Now I've sent the console to Nintendo for repair and they've serviced it and it's on it's way back. I'll let you know the results.

did you format the sd card with the switch first, and download/drop the `boot.dat` from the https://sx.xecuter.com/ website?

wont let me because i don't have exfat support i'm on 4.1. I formated them with guiformat32 on my pc.

i give up. updated my 4.1 to get exfat to see if that fixes it.

Update the switch with the latest firmware , format the card with the switch after that copy the .dat .
And it should solve your problem

did, same result.

Just to be sure the sd card slot is working.
Does the SD card detect in the Switch when you pop it in while its on?

 

[gamer4lif3]

If u can't t even run sx os with pc then your sd cards are fake or sd slot broke?

Ugh, looks like you are doing something wrong. Did you format SD card and place only boot.dat to the root of microsd?

 

[Nollog]

If you haven't already, try redownloading the dat file. Maybe the download or transfer got corrupted.

i've downloaded several times, i've used version 1.0, 1.2 and 1.3.. same thing.

7zip made no difference.....

Same problem here on 5.1, I used hekate before and do have a 5.0.1 backup, so I’m upset that it stopped working as soon as my sx pro arrived.

 

[BlastedGuy9905]

Put boot.dat on the *root* of your SD Card.

 

[gamer4lif3]
