ok i followed many tuts but i already knew but just wanted to make sure.
Everytime i install v5 of desparter ..., and i activate the battery and put it into a bricked psp or psp that wants to be downgraded, the psp turns on, i don't know why and if i follow the exact same step and do v4 which install 3.80m33, it works but v5 installs folder called tm in it a folder called DC5. any help is grately appreciated

that's time machine something that dark alex added in dcv5.

dcv5 are now integrated with the time machine, so if you did not installed the timemachine ipl, dcv5 may o may not boot up depends on the config.txt, just install first the ipl loader for timemachine, then reinstall the dcv5 then it will ask what button you will be used, (mine i;ve used the left dpad button) then after you press it in a couple of seconds, it will install dc files, then when finished, check if it will load when you press left button, if not, check the config.txt in the TM folder and try to change the configuration

thanks alot everyone, youve been a great help because this has puzzled me for a while now
