But when you play with custom kernels, you should have that, right?<br /> <br /> From the WebOS Doctor Image you'll need to extract the (original) kernel, that has been installed on the device:<br /> <br /> * open the .jar file (rename it to .zip is a hint, if you don't know how to access the contents)<br /> * inside, there is an archive /resources/webOS.tar - open/extract that one, too<br /> * inside webOS.tar, there is an archive nova-cust-image-rootfs.tar.gz - open/extract that one<br /> * inside the rootfs, in /boot there'll be the uImage you're searching for. For 1.4.5 the file is named uImage-2.6.24-palm-joplin-3430<br /> <br /> memboot is a feature of [[bootie]], the bootloader installed on the pre. To get into bootie mode you must:<br /> <br /> * power off the phone<br /> * put in a USB cable connected to your computer<br /> * hold the volume up key, while powering on the pre<br /> <br /> Now you should have that big usb-resembling log on the screen<br /> <br /> Start the memboot using<br /> <br /> novacom boot mem:// &lt; uImage-2.6.24-palm-joplin-3430<br /> <br /> (specify the name of YOUR kernel, of course)</div>
