On Device Flashing. Download one of the kernels below and place it on root of the mass memory, otherwise known as MyDocs. 700mhz 750mhz 800mhz 825mhz 900mhz Run X Term and become root, then type fiasco-image-update /home/user/MyDocs/zImagexxx.fiasco Replace the xxx with correct mhz number, e.g. if your flashing the 800mhz you need to type fiasco-image-update /home/user/MyDocs/zImage800.fiasco Remember X Term is case sensitive. Once done please reboot. This worked for me running PR1.1 If you want to return to the stock kernel then open X Terminal and become root, then use the following command apt-get --reinstall install kernel kernel-flasher and reboot.
