i'd would be very grateful if u guys could give a toturial on how to put these prx themes from the start..

press select, set usb from memory stick to flash0.
then turn on ur usb. after that u'll see files in ur flash0.this one if deleted will brick ur psp.so do it carefully.
then select all. copy. and paste it to whatever u want in ur hdd. this is ur flash0 backup. if u're on slim,make sure u backup ur nand.in case anything happen u can revive ur psp using pandora.i dont want to tell about how to do the nand backup.go google.this is not the place.
after backup is done. now extract ur theme.make sure ur theme downloaded are meant for ur firmware.this is crucial.3.80 theme are made for 3.80, it's not for 3.71 or 3.90.remind that.if u are unsure ur downloaded theme is for what firmware,delete it.dont mess with it.same theme with same name also have different firmware it is made.because maybe at first the developer made it for 3.71, then later 3.80 out, they modify their theme to fit on 3.80. ok?
after extracting ur downloaded theme, there are few folder such as vsh and resource. ok now copy ur extracted file and paste it to flash0. just yes to overwrite everything. after that.. turn off ur usb mode.and restart ur psp.if everything is ok.u should see ur new XMB.
ok. now if u want to change to another theme... make sure u copy all ur flash0 backup to your psp back before u copy another new theme.this is because a theme sometimes overwrite certain file only.the main reason to copy ur flash0 backup to ur psp is to make sure it's fresh with all original files. then after that only u copy ur new theme like steps before this. me usually only copy necessary backup file to flash0 back since if u want to copy everything back,it's like too much and time consuming.
good luck. try at ur own risk.

**edit. make sure ur battery is enough ! a sudden blackout while flashing will brick ur psp.
