Write custom fw M33 3.71-2 to ANY model psp

Intro:

Lots of questions pop up in these forums lately on how to install Despertar del Cementerio v3 (DCv3).
Numerous threads on the matter are created, because the newbies can’t find their answers.

This is not a complete howto, but should get people in the right direction.
And if they do have any questions, they can ask here instead of starting a new thread.

What is DCv3 ?

DCv3 is a powerfull tool created by the greatest devs in the psp scene. It is an evolved version of the Pandora’s Battery. Pandora was first created to unbrick psp’s. However Pandora wasn’t compatible with the psp slim. Therefore DC was coded. The latest version (v3) has full compatibility with classic and slim psp’s.

DCv3 allows you to:
- Write custom fw M33 3.71-2 to ANY model psp (regardless of fw version) to date
- Write official fw 3.71 to ANY model psp (regardless of fw version) to date
- Create a nand dump from the psp (the nand holds the fw on the psp)
- Write a nand dump to the psp.

NOTE: DO NOT USE A DUMP FROM ANOTHER PSP. IT WILL DESTROY THE IDSTORAGE. THERE’S NO WAY OF REGENERATING THE IDSTORAGE. THE ONLY WAY OF RECOVERING THE IDSTORAGE IS FROM A NAND DUMP FROM YOUR OWN PSP. THEREFORE ALWAYS MAKE A NAND DUMP BEFORE YOU DO ANYTHING WITH DCv3 !

To let the memstick do it’s magic you’ll need a battery which will put the psp in ’service mode’. There’s several options how to obtain such a battery.

1) Create it with a homebrew capable psp. That’s a psp running cfw or official 1.50 fw.
2) Create it by hard modding a battery. This is not for beginners, it is potentially dangerous as you are opening your battery.
3) Buy a battery from the internet. Your on your own on this one, as I do not promote the financial exploitation of psp devs.

Once you have the battery all you need now are the correct files on the memstick. Once again there are several ways of putting them on.

1) Create the stick using a homebrew capable psp.
2) Create the stick without a homebrew capable psp.

That’s all the options we have. Now you know what DCv3 is, where it came from and how you can get it.
I’ll put all the needed downloads and information below here in links and attachments.

Downloads:

If you do not have access to a homebrew capable psp use the folowing files:

- Memstick Easy Installer Run it by clicking Start.exe follow the prompt and choose Option 4.

- Hard modding your battery This will tell you exactly how and which chip to alter.

- Free service Go here and let someone near you create you a DCv3 kit.

If you have access to a homebrew capable psp (slim or classic) use the following files:

- To create the DCv3 yourself you need the 1.50 eboot, the 3.40 eboot and the 3.71 eboot. Also use the DCv3 attachment.

- To create the battery use one of the two tools. Slim users and classic psp with M33 3.71 without 1.50 kernel use the 3.xx tool.
Both tools will also allow you to convert your battery back to normal.

That should get all of you started. I know it’s not complete. For usage of DCv3, check the readme included.
