Answers:    you cant simply update to a custom firmware.
if you are on the butter psp, then you first call for to use a pandora battery to downgrade to 1.50.. later to update to 3.71m33, you have to update to 3.52m33, later update to 3.52m33-4, then you update to 3.71m33.
if you enjoy a slim, then you install 3.71m33 next to the pandora battery.
an administrator firmware update requires just 1 folder.
for the fat, updating to a cfw (after you are on 3.52m33-4), you stipulation the 3.71 official firmware update, the 1.50 chief firmware update, and the m33 cfw.
on the slim, you need the 3.40 sanctioned firmware update, the 3.50 official firmware update, and the m33 cfw.
where on earth did you download 3.71 m33
what Website???
