can i format my memory stick after i have put cfw on my psp slim?

Reply to this comment

Hi Adrian,
Yes, you can format your memory stick after the CFW is installed but you must use a regular battery or the AC adapter. If you continue to use a service mode battery, the PSP will check the memory stick for boot code. If none is found, the PSP will not boot until either a regular batter or AC adapter is used or you keep the boot code on your memory card.

well what i did was i drew back the #19 line with a led pencil and it works perfectly it boots the psp without any problems

Reply to this comment

anyways thanx for this guide it did work on vista and i finally have cfw on my slim

Reply to this comment

Great to hear Adrian. Just out of curiousity, what brand of memory stick are you using? I’ve had success with two Sandisk memory sticks but some people seem to have problem with Sony brands.

Hi Len,

Excellent website, the only one ive seen that explains what, why and how. Excellent.

Ive just sorted out my battery for service mode, but just have a few queries before i go ahead, and would appreciate the help. Im currently using a slim 2003 model + has OFW 4.05. Will this make any difference at all to your process? Sorry im so new i wouldnt even class myself as a noob.

+ 1 last thing, OFW 3.90 from the link you gave will not download, it has 3 errors. Do you know of any other links?

Cheers in advance

Hi Lewis,
Glad you enjoy the web site. I’m not 100% sure if your slim model 2003 with OFW 4.05 would work as described. I would assume it will but I can’t be sure. If you do try, please post your results. The link to OFW 3.90 on the Step 1 page appears to be working. Either you caught it at a bad time or you need to install WinRAR to open the .rar archive. Good luck!

Reply to this comment

Hi again,

Well tonight was the night for me to get cracking, but i cant even get passed step 1.

1 – i have downloaded & extracted OFW 3.90
2 – i have the correct PSP Grader that you advised.
3 – i follow the pretty straight forward instructions and all i get is:

“Access to path ‘C:Program FilesPSP Graderinjectipl.cmd’ is denied.”

So sorry to be a pain in the @$$ on step 1, but any ideas? Im running Vista, with PSP Slim 2003, Sandisk 2GB, OFW 4.05.

Maybe something to do with “administrator privalages” – but i am the administrator and havent had any further options to allow the process.

Thanks for prev reply, hope to hear again,

Lewis.

It worked for me however, I bought the PSP in the States and I cant get UK UMD films to run as it region coded.

Reply to this comment

hey lewis i had the same problem your right click on psp grader and click run as administrater if that dosent create a magic mem stick then i would reccomend using windows xp

Reply to this comment

Hi Len,
This HOWTO is absolutely great, as I just bought a psp slim.
Just thought I’d let you know that downgrading from ofw 3.95 to 3.90 m33-3 worked perfectly, and plays games/homebrew fine.

Reply to this comment

Hi Lewis,
As raj has already said in comment 14, please right-click PSP Grader and click Run as Administrator. Please let me know if that fixes your problem. Good luck!

Hi William,
Glad you enjoyed the tutorial and were successful with your own PSP. Thank you for posting your experience.

Hi Matt,
When you are in the M33 recover mode (Hold R during power-on), you can go to the configuration and enable the “Free UMD region” option. Please let me know if that solves your problem.

Hi Charles,
Glad you enjoyed the tutorial and thank you for posting your experience. Very happy that it worked for you.

One more question. You said you enjoy running SNES9X on your PSP, however I can’t seem to get it to run. Do you have/know of a tutorial on how to get it working?

Thanks again,

Hey everybody,

I’m having a problem that doesn’t seem too common amongst everyone else’s. I accidentally broke the one foil piece across from the knob end of the battery (that part is common), and I thought I fixed it by putting some aluminum foil between the severed pieces because now a light actually comes on when I try to charge it in the PSP. However, it was flashing between green and orange for a while until I tinkered with it and now it’s back to the normal solid orange. I’m hoping it’s actually charging right now, but I can’t be too sure. I tried the steps in the guide several times and nothing was showing up on the screen. I’m worried that even if the battery does charge, it’ll be too loose or off or something in order to complete the firmware upgrade.

hi bought my psp slim june08 with 4.50, downgraded to 3.90 m33-3 all works great thanks

Reply to this comment

To everyone that visits this site this is a amazing site that will work if you follow the instructions i am fully impressed and am now free from SONY

for this i thank you!!!

Reply to this comment

Just got a used PSP fat. Since it is an old model, it does not have any problem hard modding the battery and putting 3.90 m33-3 on.

However, I cannot find any settings on the 3.90 m33-3 service menu that state: Charge the battery while USB cable is connected.

Does it mean it is not supported in PSP fat ?

Also, from 3.90 m33-3, how to I upgrade it to 4.01 m33-2 ? There is a large 4.01 OFW download and small 4.01 CFW m33-2. How do I use them ?

Reply to this comment

Thanks! that worked great

Reply to this comment

Hi Fatice,
The charge PSP though USB is an option only support on the PSP slim models. After you have 3.90m33-3 installed, you can use the Network Update feature to automatically download and install the latest version of M33 to your PSP.

Just wanted to say thanks for the tutorial. It was easiest, most straightforward guide I’ve come across. Now I don’t have to carry all my umd games around with me to play.

Len,

I’ve seen your question in the comments about if the sony memory sticks work and stuff. Well I dont have a Sony one but just to let you know Lexar MagicGate brand works perfectly fine.

Reply to this comment

Solid Guide!! I’ve been looking around the internet for ages for a decent step by step guide by someone who knows their stuff, but could never find it.

Will give this a go tomorrow, but it looks pretty straight forward (at least in comparison to iPhone hardware unlocking (that was scary))

Shall post my results. Keep up the magnificent work.

Worked brilliantly except!!

I had an official Sony Memory stick 4GB (pro Duo) didn’t work with any injection software I tried. According to PSPGrader forums this is happening to a few people.

I got a Sandisk, worked fine. Who knew that ebay sellers actually sold legit stuff on the cheap?

Thanks alot

Len,

I have modded the battery as u told to do and the green light turned on by itself. But when i am trying to flash the firmware, nothing seems to happen. Just the green light turns on by itself and nothing appears on the screen. What do u think the problem is?

Maybe next you can tell us how to install cwcheat?

Reply to this comment

Best guide I’ve seen, and only one that doesn’t assume you can get your hands on a second PSP running 1.5 in order to mod your PSP.
I have an original PSP phat running 4.05. Will these instructions work for this model? Does the original phat battery also have a trace 19 for a hard-mod Pandora, or do I have to do something else to the battery? At least one other guide mentions removing a pin amid warnings that the battery could overheat or explode:)
Thanks!

Can this mms and pandor battery be used to unbrick ???

Reply to this comment

Hi skater and g boy. The chances of bricking the PSP by following these steps are pretty slim. Although you take a bigger risk to damage your battery by opening it up and cutting the trace wire. The PSP battery is a very sensitive piece of equipment and it can break very easily. Fortunately it is easy to buy another one but it is better not to break it in the first place. Breaking the battery or possibly the whole PSP is a risk you take if you choose to follow this tutorial. Please make sure to read and understand the entire tutorial before doing any of the steps. The better you are prepared, the better your success will be. Yes, the battery and memory stick combination to unbrick a PSP assuming the PSP and battery have no fatal hardware damage.

Hi WackoMak, the PSP requires a service mode battery to access the firmware utilities. If you do not want to make your own service mode battery and you don’t know someone that already has one, you can search the `net and find some places that sell pre-made batteries.

Hi Zohair, some people have reporting problems using PSP Grader with Sony memory sticks. Please try a newer version of PSP Grader or an alternate brand of memory sticks. I’ve had a lot of success with SanDisk brands.

Hi iyeru, cwcheat is great homebrew. You can download it from http://cwcheat.consoleworld.org/. Usually it is as easy as copying the “seplugins” folder from the “INSTALL” directory of cwcheat to the root of your memory stick. Reboot your PSP when you play a supported game, hold down the SELECT button for a few seconds and the cwcheat menu should come up. Not only can you cheat, it will show you the remaining battery life while in a game.

Hi KillerTigger, the instructions are almost the same for a PSP phat but it is a slightly different process to make your own service battery. You can find tutorials on other sites or you can order a pre-made battery. Good luck.

Cheers Len for a fantastic HowTo

Just a little question (as i’m a noob) and trying NOT to brick my son’s friends PSP :p
If you got a bootable memory stick and a pandora battery, would i be right in saying that i would only need to follow step 3 to do a PHAT PSP with OFW 3.52????

Thanks a lot Len

It worked thanks but what is the chance of the psp randomly bricking and Can this be used to unbrick other psp slims ???

Reply to this comment

Thanks Len!

I had been researching for just a few days on how to mod my PSP when I found your excellent guide and I am pleased to report everything came out wonderfully. Had almost zero trouble (as instructions were nearly foolproof) and accomplished the task in around 2 hours – after extensive reading & re-reading beforehand (just to be doubly sure). I used a PSP slim Daxter bundle V3.80 with a 1GB Sandisk memory stick, if that helps anyone. Mostly just wanted to say thank you for this incredibly simple, excellent guide. Highly recommended to anyone who is considering going with a custom firmware.

is there a new mother board that dosent work

Reply to this comment

I took your word for it and attempted to install the custom firmware. I can’t say it was nothing short of a complete success. I got through each and every step without any problem whatsoever and I’m happy to say i am now running 3.90 M33-3. Thanks so much for this guide, its probably the best one out there.

Reply to this comment

hey… at first it didnt work… im using a lexar 4gb magicgate mem card…

if it doesnt work at first make sure the battery is FULLY charged… i didnt know if this was the problem… but i used the program stated to make the firmware bootcard and FORMATED first after trying not to format and it worked…

so i hope this helps people… ive never modded anything in my life and this was a big help… THANKS SO MUCH …

ps i wouldnt spend money on a pandoras battery either… when it takes 5 mins to open up your own battery and cut a slit in a line… i did it without useing a mag glass…

doing it yourself is way better anyways then cheating!!!

Reply to this comment

Thanx for your advice len. I tried the same process with a sandisk memorycard and it worked. I dont know what is the problem with difference in brands!! Anyways thanx. Maybe you next article could be of installing cxmb or something.

Hi Len, thank you so much for making this guide! I’ve owned my PSP for only about 4 months now and I was looking forward to modding it, but scared because of all the crappy guides out there that didn’t really have much information or tell the user what was going on. Your guide is simple, concise, yet still tells us what exactly is happening with the system. Thanks again!

I do have one question: Is it necessary to have the Pandora Battery in the PSP when you want to use custom firmware? (I’m assuming it is since you have to boot off the memory stick via service mode). I bought a larger battery, along with a replacement cover, from eBay and it has a much longer life to it. The battery was made in China, and isn’t made by Sony, so I haven’t been able to find any ways to hard-mod it. (You get what you pay for I guess; thing only cost a couple bucks)

good work on this tut man, it help alot, thanks =D

and does anyone know if this guide works on a phat PSP?

i know the battery is different because of it being a phat battery, and for people wanting a guide for the phat battery, go here: http://forums.benheck.com/viewtopic.php?t=21280

I did everything to the “T” but my psp slim 2001 w/ 5.01 OFW will not boot up into the service mode. I made sure the line 19 is cut well. Multimeter shows no continuity and yet the psp acts like nothing has happened. BTW, My original store bought firmware was 4,01 I believe and I upgraded to 5.01
