for all pre x20 models like the x00's, Ones & One XL's, x10's (510/710) but NOT the 910, (that were not designed to read SDHC's or have not previously seen/booted from an SDHC card) you
first need to load a suitable bootloader (system file) to enable the device to actually boot up from your new 4Gb SDHC Truck card. The easiest way for you to do this is to copy/paste/overwrite the "system file" (extracted from the attached 5.5120 system file.rar) or from any of these downloaded dumps 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
You MUST do this BEFORE your device can read an SDHC card
