Hacking Upgrade PSP 3.80 M33-5 to 5.50 GEN D3?

[heyimanoob]

Hey again,

So my friend left me her PSP in which she hasn't used for the past... 7 years? It was a pretty long time and when I opened up her PSP, I saw that the system was still 3.80 M33-5. Mine was 5.50 GEN D3 but upgraded it to 6.60 with a CFW a few moments ago.

She wants to upgrade it to 6.60 but I already know how to do that. What I want to know is how to upgrade 3.80 M33-5 to 5.50 GEN D3 (I know the procedure on how to upgrade it to 6.60 from there).

Thanks.

You could update to 5.00 M33-5 ?

I think you put 5.00.pbp on the root, and launch El Despertar Del Cementerio v8.
But check tutorials to update and use it correctly, it probably require you to make a "magic memory stick" or pandora battery.

I've found tutorials to install 5.50 Gen D3 (but in french, you probably won't like it).
tutorials seems to be either french or spanish...

Might as well just update to 6.60 and use one of the newer CFWs
