the "deinstall" menu item is very experimental. It doesn't work with LR1.2 (which I'm running). it basically does the same as http://wiki.maemo.org/Kernel_Power#Deinstallation I'd appreciate if you could test the following commands manually (not the menu item) and send me the output. Code: sudo gainroot apt-get install --reinstall -y kernel kernel-flasher apt-get remove -y kernel-power kernel-power-modules after that you can install kernel-power-flasher or settings via HAM again.
sudo gainroot apt-get install --reinstall -y kernel kernel-flasher apt-get remove -y kernel-power kernel-power-modules
