@kyllerbuzcut,

OK. So issue is (apparently) not related to KP48, and therefore off-topic here

If I were you I would completely remove any traces of any speed/battery "patch". I have actually spent a few minutes having a look at that thread and have come to the conclusion that I wouldn't touch any of those things with a (long) stick!

BTW, reboots are usually caused by activating SmartReflex (VDD1/2). There is a reason why Nokia disabled that by default. Also using low voltage profiles may make your N900 go crazy (including rebooting).
