I assumed it may just be a quick process like that, but when I try to apply the lag fix, and install the ext2 tools, it tells me that i need to root my phone to work. Otherwise i dont know any way to check if my phone is rooted.
Obvious question, you select the 1st option in OCLF to root your phone (does it show up in a green box?) the update.zip file is created and then you are proceeding to turn off your phone, do the Volume Up+Home+Power to enter recovery mode and apply update.zip, right?
Also, I believe the one-click root process does not work in JPC.
