Hacking Hardware Keep getting boot.dat error. Is card reader broken?

[Tom_Blums]

Hi guys!

I have a mariko switch witch sx os modchip and sx os loader on it. I have prepared my microsd card(formatted in fat32) accoarding to this tutorial: https://rentry.org/mys8q. But I keep getting this screen with "boot.dat?" error. Am I doing something wrong? Or is sd card reader on my switch broken? If so, how could I verify that?

Your carye SD is in FAT32? In your previous message you said it was in FAT 32. But check. If there is no "no SD" error, it means that your SD card is recognized. So the reader is tired of breaking. If your SD card is in FAT 32 then try downloading the HATS pack on GitHub.

It might caused by card reader, I faced few month ago.
Solved after replace the card reader.

The card is in fat32, and in windows the card works flawlessly. But the sx os bootloader does not see the boot.dat file(which is located in the root of the sd card). The bootloader shows that "boot.dat?" error. Even if I try to boot switch without the sd card, it still shows me that "boot.dat?"error message, so it looks like sx os boot loader does not show any "no sd card" error messages.

Is far as I understand, the HATS pack does not work with sx os bootloader.

Humm. Try to change the card reader.

Thinking about this I modded my cousin's switch he also had this problem when his SD card wasn't supported. What brand do you have I suggest a SanDisk

I guarantee it's a unsurported SD card with the modchip

This sd card used to work with this switch before. So the sd card is 100% compatible with this switch.

Boot in OFW and insert sd-card?

I dont think it is possible. Even without the sd card inserted, the "boot.dat?" image shows up. And it does not let me boot anywhere further.

Have you find a fix to this issue?
