Hi,
I recently got an fat psp. and it has official 3.52 installed. I want to upgrade it to 3.71m33-3. I did one before it was on 1.5 version and seems really easy. But I want to upgrade now directly from 3.52 to custom mode and of course with-out the downgrade/or by using Pandora. so is it possible? I want a solution please. Because its may be boring with-out home-brew. anyway..
thanks.

You can't downgrade from 3.52 without a battery.

lol, I just told I don't want to downgrade either. And want to upgrade from current official 3.52 to custom 3.71 m33.

Thanks for saying that, exactly this thing I want to know. (but confuse )Can you please explain more about that or how to do -- because avoid risk of bricking psp.

Thanks I am going for it now.

Hi, I am back once again. With same problem, I was busy to making the Pandora thing all I got is bundle of software’s. But I realise that there no tutorials I haven’t find so far is to how to make Pandora battery with using an official firmware? My version is 3.52. I also heard if you have official 3.52 then it’s not possible to downgrade, is it true?

There all other sites just describing how to downgrade psp, making Pandora battery and only for custom firmware users

Is there nothing to do who have official firmware like 3.52? Is it the dead end of the homebrew if someone buys psp with official 3.52 or upgraded accidently to official 3.52?
Please somebody give the better idea.

Thanks so much for wasting your valuable time for this.

You cannot install Custom Firmware on a PSP with a Firmware of 3.51 or higher, without using a Pandora battery.

In order to install Custom Firmware on a PSP with 3.52 OFW, you will need a Pandora's battery, and a Magic Memory Stick.

I know about it and hearing almost from beginning of my problem. But people say the official firmware 3.52 can’t be downgraded. What to do??

Why are you suddenly concerned about downgrading? Earlier, you stated that you didn't want to downgrade.

In order for you to achieve installing, Custom Firmware 3.71m33-3, you need to have a Pandora's Battery, and a Magic Memory Stick.

Actually it’s about to upgrade in 3.71 m33. Whatever it is, if it’s related with downgrading. I want to follow any process that brings me on the version that I want. I told I don’t want to downgrade if there other ways. Hope-fully no way’s at last, so I don’t mind to downgrade anyway. So how do make that Pandora things worked with official 3.52.

And the link you gave me is perfect. But it’s hacking the hardware, and I am looking for software for 3.52 to make it happen. if there no software then of course I must go for hack the hardware.
Thank you.

OK thanks for your help and I figure it myself (actually looking on other forum from web). The thing is if you have 3.52 or higher, than there is no software to downgrade (to upgrade to CFW). Only way is, you must make/buy Pandora battery. The way with-out Pandora may be available but they are too advanced for basic user.

Ah OK, I believe open the battery case and cut a pin from motherboard not very difficult (at least I can do that). Thanks to those who make it lots easier. So if someone waiting for down grader on official 3.52, then I suggest go for hack the batteries motherboard, things you will need is confident. Not to fear and of course you can make you battery to normal after use.

Why? its a very common method for create a Pandora with FW3.52.
Information can be found all over the web. also in youtube

and also there no other ways for official 3.52 users.

Don't do that if you lack experience, because if you break the battery, you're toast. You'll end up having to purchase a Pandora, and an entire new battery just for the PSP's power source.




Why are your posts always blissfully contradictory?

That was exactly what I posted earlier, but it looks like you've come in this thread blind eyed to my help.

yes mate this the only option for FW 3.52 or above users. And I am preparing for all the things that need for downgrade and I will replay if there any luck. its may be take a little long because first time doing it.
thanks

ah h OK almost forgot about it. phat psp already have it inside 1Gb pro duo (sandisk) I am lucky..

I predict a brick in powermax's future...

Hey guys sorry for late replay. I successfully installed the required firmware. So you must need a Pandora battery for 3.52. If you want to make your own then you must open the battery case.
There is no software for 3.52. You can make magic memory stick with vista. You need to turn off user account control and take the full access of the pc by taking the administrator account. That’s it, and then you need to format it manually by right click.
