err guys i'm a very n00b to homebrew, can anyone help me on this? i got a 1.5 and wanna update it to Version 3.10 Open Edition. i have downloaded Custom Firmware 3.30 OE-A from PSP Hacks but i found the instruction in the read me kind of confusing.

wat does it mean by "Instructions are as always, oeupdmaker to create the dxar from 150.PBP and 310.PBP, and 310oeflasher
to install the firmware from the dxar previously generated."

unzipping the file downloaded give me 4 diff folders,
310oeflaser
310oeflasher%
oeupdmaker
oepdmaker%

all 4 folders have EBOOT.PBP files. Please help!

Thanks so much King83 it really helps! gonna do it tonight my batt running low will see it works or not.
