Thread: Navcore v9.541 SE for One/XL 32MB by Tonyzeta

Correct!
Virtually all larger capacity SD cards and microSD cards are now classified as SDHC and will not run in older devices without changing the system (bootloader) file.

This applies to all pre x20 models like the x00's, x10's (510/710), Ones & One XL's (that have not previously seen/booted from an SDHC card).

To check what bootloader you're currently using tap bottom/right of your screen then tap the "version" box where you will see the Boot number. If this is lower than 5.5120 then you need to change it. If you're already running an SE or other "special" navcore you've most likely got a suitable bootloader (5.5120 or higher) already so you can ignore these instructions.

The easiest way for you to change the bootloader is to copy/paste/overwrite the "system" file (extracted from the attached 5.5120 system file.rar) to your current standard SD card or internal memory and boot up once with that new system file then it will read your new SDHC card.

DO NOT just add this bootloader system file to your SDHC card and expect it to run. You MUST first load it to your original SD card or internal memory and start your device. THEN it can read SDHC's.
