need help to install cfw

hey im tyrying to install CFW on a friends PSP but when I put my battery in it just boots up like normal why?

Because the battery youre using isnt pandora. Either that or you have the ac adaptor plugged in while trying to use pandora.

no its a pandora and we dont have the ac addapter plugged in

Well then i can clearly tell you that your battery isnt pandora if your ac adaptor isnt plugged in. A pandora battery without mms will bring up a black screen and the power light will stay on. With mms inserted with your pandora it will boot into service mode.

If it was once a pandora battery, chances are you or someone else converted it back and completely forgot. Either that or you've gotten your regular battery and pandora battery mixed up.

*EDIT*
Make sure youre holding the L Trigger while you put your battery in as well.

I used the totalnewbinstaller, did everything like it says, pandorized my battery, and when I put the battery in with the mms already inserted, the green light comes on and that's all, it doesn't try to read the memory stick or anything. What did I do wrong?

skater are you on a phat psp or slim?
also try holding the L trigger when you place your battery in.

if that doesnt work....

1) Download and install PSP Grader v005 Lite by Klutsh.

2) Download Official 3.90 EBOOT and extract the EBOOT.PBP file.

3) Start PSP Grader and connect your PSP to your PC. Make sure to backup your MS because this will format it.

4) Click on the "Load eBOOT" button and locate the 3.90 EBOOT you just extracted.



5) Click on "Booster's Mulit IPL" and on "Format Memory Stick".

6) Now the best part, click on the "Create Pandora Stick" button on the bottom right.

When it's done click OK. You now have a MMS.

As for your battery, you'll have to hard mod it. Which consist of opening it and cutting a small pin. I've never done it before so I can't help you there. You will be able to use it as normal by using the "pencil lead" trick.

If you want you can send it to me and I'll soft mod it and send it back that same day. Soft modding is also reversible and is the best option in my opinion.

To install CFW..

1) Insert your MMS into your PSP.

2) Hold down the left shoulder button and then insert the Pandora Battery.

3) Press X on "Despertar Cementerio v5"

4) Then press X to install 3.90M33. Wait untill it's done and press X to shut down. You now have CFW.

Thanks, staxx. I finally got my GoW PSP to 3.90 M33-3.
