[GUIDE] Upgrading to 3.71 M33

[Bobtentpeg]

Same warning apply. WE are not responsible for anything bad Yada yada yada.
Dark_Alex is amazing and deserves a lot of thanks.

3.71 M33 by M33=Dark_AleX
Changes in 3.71 M33:



- Now uses 3.71

- VSH Menu is not longer launched using HOME key, but using SELECT now. This is to not
interfere with the XMB function of home, which is now more useful in this firmware.

- Psp Slim: umdcache was allocating memory even when homebrew was launched, wasting

memory that homebrew programs may want to use. Now umdcache module is stopped before

it can allocate any memory, only in the case homebrew is launched.



Also, memory is unprotected for user memory usage by M33 core (only when homebrew is launched).

Developer, for a sample of how to use the extra memory, see the extra ram sample of the M33 sdk.



- Both version boot now from 3.XX ipl, and are independent of 1.50.



The main installer will not install 1.50 kernel anymore.

A 1.50 kernel addon for 3.71 M33 that will install inside 3.71 M33 EDIT: It now releases and guide has been updated
few days (for fat only)



Note: due to some changes in kernel nids by Sony, you can expect a lot of kernel plugins not working anymore.

Requirements: a fat psp slim with 3.52 M33-3 or 3.52 M33-4NOTE: If you have a custom theme you will need to remove it. Previous versions of M33 won't work, due to a bug that affects them and OE; or a psp slim with 3.60 M33.

I just updated my slim - it worked OK.

Do you know what the sdk folder is and what do i do with it? There is a read me in it but doesnt give any indication.

Sorry but Im a noob at this psp business.

[Mick0204]

So is there no getting straight here from Good 'old 3.03OE's?

Not even if I jig it down to 1.5?

I guess I'll look into how to load the M33 OE prior required. .. unless any of you kind gents has a better suggestion. THX

[Bobtentpeg]

you will need to update toe 3.52 M33-3 or 4 first

[Asayu]

is this firmware 2.71 compatable or do I have to downgrade to 1.5 first?

[Bobtentpeg]

you will need to downgrade to 1.5 (tell me which mobo you have ta082+ or nonta082 and I will submit a guide to downgrade that)

then upgrade to 3.52 M33 then -3

Please take off the OE bit from the end of this topic - it's stupid, as it's M33 - even if it was coded by Dark_AleX.

Edit: Thank's for changing it

What am I doing wrong?
I'm a noob & I finally made it to 3.52 M33-4. Now I'm trying to get to 3.71 M33. I added 371.PBP & EBOOT.PBP to PSP/GAME/UPDATE, but I keep getting corrupted data. I also tried it with umodule.PRX, but I got corrupted data again. I even tried dropping everything I extracted from the 3.71 M33.rar file, but I still get corrupted data. Could someone PLEASE tell me what I'm doing wrong!
