Hacking Homebrew Installing custom FW on PSP Slim

[suppachipmunk]

Hello, I am a complete Noob to teh PSP scene. I am planning to buy a PSP Slim in the next few days and I just wanted to make sure that I know how to mod it first.

I did some research and I know that I need a battery (Pandora's battery) and a compatible memory stick with the appropriate files on it. I plan to buy the battery from datel (codejunkies.com) because I have NO way to make my own battery. When it comes to the memory stick, do I need to do anything special other than just drag and drop the necessary files onto the memory card?

If anyone can give some step by step instructions, or even a link that may answer a few of my questions I would greatly appreciate it. I did a search but couldnt find any definite answers to my questions. Just figured I would ask for some advice from ppl who have already done this before.

I can get the battery already formatted, and I can get a retail memory stick, and I can get the files. Is there anything else special that requires an already modded PSP?

Thanks in advance.

nice topic on howto make a pandora battery/ms to directly install 3.71 M33

Thanks worstenbrood, I will give this a read and attempt hopefully in the next week.

afaik, you need a psp capable of running homebrew to make the memory stick too. at least thats what i hear.

There is a way to make a pandora battery with some soldering i think, dunno if its possible to make a ms without a modded psp

Only the latest firmwares need the Pandora stuff.

Check psp-hacks.com to see how to hack your particular version.

God...there was this site I saw that explained how to make a battery that would reset you to 1.50 with just soldering...maybe you should Google search for it, but I don't know if Slims can downgrade to 1.50. I'd rather just get a normal PSP lol.

 

[Samutz]

Currently, Slims are unable to downgrade to anything below 3.60. The only FW options for it are 3.60 M33 and 3.71 M33-2. I read on some news post (don't remember exactly which site, might have been M33's release post) that this was because something in the Slim's hardware prevents it from running anything lower than 3.60.

At the moment, I'm running 3.60 M33 because I had heard that 3.71 M33 wasn't working very well. This may have been before M33-2 was released, so whatever problems it might have had may be fixed now.

yes, you can open up the battery and remove (or cut one of the connectors) to create a pandora battery. however, getting the files onto a memory stick may be another issue. I'm planning on updating my new psp slim by the end of the month, so I'll probably take the guides that out there and try and fill in any blanks that exist.

I'm running M33's 3.71 on my phat psp so far without any issues (however, it may be 2nd update that I'm running).

The only issues I have right now is the "lag" that happens while changing screen brightness. But it doesn't happen while playing a game, which leads me to belive that it's the le recovery menu's fault (most likely since I modified the brightness there).

Other than that, 3.71 m33-2 is great (even with out the update)

 

[dsbomb]

There was some news today about possible corruption from 3.71 M33-2. So you may want to check up on that.

 

[Samutz]

Ah. Chuckstudios is the one who told me he didn't like it. I trust his opinion cause he's helped me a lot with my own noob questions.

[06:24pm] chuckstud, you tried 3.71 M33-2, right?
[06:24pm] yes
[06:24pm] i disliked it
[06:24pm] and it sucked?
[06:24pm] it's ok
[06:24pm] i just didn't like it
[06:24pm] dunno why
[06:24pm] hm
[06:24pm] im still using 3.60
[06:24pm] oh
[06:25pm] if you have a slim
[06:25pm] and i keep seeing this shit thats like, "only for 3.71"
[06:25pm] 3.71 is worth it

So I'm updating right now.

News from where? I haven't seen anything today on the sites I typically check.

I have no idea what any of it means being I don't have a PSP, but it sounds like it sucks. How bad is it?

 

[Samutz]

I think I understand it. It's when you're messing with the files directly in the PSP's nand flash memory (such as the CFW) rather than the MemStick files, which is something you don't do often if you're a general user like me, and not a developer.

I've already replaced files in my flash0 to get applecor working, but haven't had any problems like the ones described in the post.
Of course, I keep backups of everything anyway.

Thanks for the link.

Any good place to buy one of these special batteries, beyond ebay? I keep hearing about this Datel Tool thing but I haven't been able to locate one.

PSP Slim Tool Battery

PSP Phat Tool Battery

I'm also finally caving in and getting a PSP Slim. i'm planning on getting the "tool" battery. The only issue I have is when I was reading about the 3.71 M33 FW, it said, "Once again 1.50 homebrew is incompatible on the slim but a kernel patch has been released for the PSP-1000 allowing execution of 1.50 kernel mode homebrew". Does this mean that most emulators won't work since I believe most are written for 1.5? It might be worth getting an old psp if that's what I need to do for most homebrew to work.

 

[Samutz]

Yes, it means homebrew that runs on the 1.5 kernel won't run on the slim normally. However, most emulators and homebrew apps are being updated to work on the 3.x kernel. My slim is already running the GB/GBC, SNES, GBA, and PS1 emulators, as well as a few other homebrew apps. Plus there's an eLoader that will load some 1.5-only homebrew on the slim (but not all).

On the topic of the Datel Tool Battery, I just want to point out that I ordered a battery from Datel (codejunkies.com) after getting my Slim and never got it. The status of my order is "out of stock" despite the product page saying "Availability: Immediate". After a few days and no answers from their email support, I decided to send it to [M]artin since he offered to install the CFW for me. They also already charged my credit card when I placed the order, and I can't get a hold of anyone by phone or email to cancel the order and get my money back.

Just a heads up if you think about buying from them. I think there are a few other places (such as Divineo) that sell the tool batteries as well.

 

[hollabackitsobi]

Datel customer support is shit, and their products are shit. After getting burned by their Games N' Music, I hate those assholes.
