EPE54B – superboot images – If you would like to use EPE54B but would like either root access or an insecure boot image (for adb remount permissions), then install superboot images with himem enabled. It is important to note that after installing the himem superboot on Nexus One, you will need to reflash your ROM in order to revert, as the himem superboot includes an updated wifi driver.
