Mariko SX Core Boot.Dat

[orapat]

Hi Guys think i found some threads on this, but most are dated and not on the SX core.

So my issue is i backed up successfully my nand
I installed sx os 3.03 beta
I actually was able to play and stuff.

Suddenly something happened and today when i booted, it went into Boot.dat. No idea why, didnt do much.

Tried another SD card, fat 32 doesnt work.

What are your suggestions and if i were to start from my nand backup, what should i do?

Thanks ahead!

Maybe your Datasystem crashed and you formatted the SD Cards wrong.

My specs on different working cards are:
Datasystem: FAT32
Partitition: Primary (the SX Core seems to ignore Logical partititions)
Clustersize: 32k

Be patient on exFAT the clustersize has to be higher. In this case try to Google which size exactly!

Take your original SD card that was working, insert to your PC and remove the boot.dat file.
Download the latest beta of SC OS 3.04, extract and place the boot.dat on your SD.
Reinsert into your switch and see if you can now boot to CFW or the SX Bootloader
Something may have gone wrong with your original 3.03 boot.dat file.

If this does not work then I would take the SD card that was working, insert to your PC and back up all the data on it.
Then format the SD card to fat 32 and place the SX OS beta 3.04 boot.dat and see if that enables you to enter the SX Bootloader.

Don;t panic as if you are getting the boot.dat missing screen with the "angry SD card face" image then you chip is working and it is just an SD card issue that you need to sort out.
