ps.: It didn't work....only installed some cfw like stuff like some 6.20 magic hidden prx thingy
get the 5.50 gend-3 update.......and also the so called 6.20 mad-002 official update
rename the eboot in the mad update to 620.pbp and place in mem. stick root
also make a copy and place this in mem stick root....rename to 550.PBP
in psp>Game>Update use the sprx folder from the mad update with the eboot from the gen update.....
go to xmb in d-3 and start the 5.50 gen d-3 update
xgen will start and ask to update to d-3
do it and it will tell you its installing 6.20
when i did it it only installed ofw 6.20
this is for research purposes only and U WILL NEED A PANDORA AND MAGIC MEMORY STICK IF YOU TRY!
PSS. NO DISRESPECT TO TEAM GEN WITH USING THEIR UPDATES....JUST THE THOUGHTS OF A MAD MAN.....
