3.52 M33-4 to 3.71 M33 Error

[PSP guru]

I got to 3.52 M33-4...but when I try to install the 3.71 update it says it needs higher than a 3.52 M33-3 program XD, but my system settings says i have higher...what am I doing wrong?

you need to go into recovery menu and change the kernel to 3.52

I did that, but it says "Reading 317.pbp....then it says Can't read error (810001 some numbers)

[Kyla666 (zzk2001)]

sound like your not doing it right

did you place the 3.71 updater in the  UPDATE folder with the Program and change the 3.71 update's name to 371.pbp

if you look at the Read me it should tell you this

here is the Files you need

and heres what the readMe says

Installation instructions:

First method for both psp, the prefered when possible:

Requeriments: a fat psp slim with 3.52 M33-3 or 3.52 M33-4. Previous versions of M33 won't work,
due to a bug that affects them and OE; or a psp slim with 3.60 M33.

- Copy the UPDATE directory into /PSP/GAME/UPDATE and copy the EBOOT.PBP of the 3.71 Sony updater
there but with name "371.PBP". Note: the program will not even show if you copy it to a different folder than that.

- If you are in the fat psp, make sure you have configured the psp to run the game folder in the 3.XX kernel.

- Execute the program, it requires 78% of battery. If you have idstorage corrupted due to a downgrader, the program
  will ask you to correct it automatically so the update can continue.

- Press X, and the Sony updater will begin. Sit and enjoy while Sony code installs 3.71 M33

- When finished, the updater will ask you to reboot (pressing X or O). DO IT. Do not skip this step
shutting down the psp by yourself, or you'll end with a brick.

- You should be now in 3.71 M33

i understand but don't understand, when i extract that file, i get two update folders, but with kinda the exact same size...XD, i don't know which update folder to put in my PSP, and also it says to

Copy the UPDATE directory into /PSP/GAME/UPDATE and copy the EBOOT.PBP of the 3.71 Sony updater
there but with name "371.PBP".

I wondering do I need the EBOOT.PBP of the 3.71 Sony Updater which is that...but theres two XD

it's talking about the 3.71 update file witch IS NOT in the 3.71m33  So you need to Download the 3.71 Update Then change the name to 371.pbp and copy it to /PSP/GAME/UPDATE  with the 3.71m33 program

then you should see a Icon witch saids update 3.71m33  Thats the one you pick From there it Will look like a Real update with the Blue screen and All BUT it's the 3.71m33
