Install PSP Custom Firmware without a Pandora Battery

The usual way of installing custom firmware is to do it via Pandora Battery and that’s where the problem begins. You have to HAVE a Pandora Battery in order to make one (which means you need 2 batteries. One that’s already a pandora battery and one that you want to convert to pandora). The easy way out of this is simply buy a Pandora battery online. If however, you have a hackable PSP (one that can install custom firmware natively), you can install custom firmware without a Pandora Battery.

Important: If you have a PSP-3000 or a PSP-2000s with TA-088v3 (and versions above it) DO NOT TRY THIS ON YOUR PSP. If you do, congratulations, you now have a PSP paperweight. This method WILL BRICK your PSP.

Also, if you’re already on 5.50 ofw, then this guide won’t work. You really need Pandora to flash your PSP.

If you want to check if your PSP can use this method for installation READ: Can my PSP have custom firmware installed?

Using Hellcat’s Recovery Flasher

Requirements:

Install custom firmware without pandora

Install chickHen R2Before you proceed to installing custom firmware on your PSP, you need to install and successfully run the chickHen hack. Read the guide and come back here to finish the installation.

How to install custom firmware without a Pandora Battery?

  • Connect your PSP to the computer in USB Mode when you have loaded ChickHEN R2.
  • Unzip the file for the firmware you want installed (if you want 5.00 M33 you have do download and extract PSP_500_FW_UPDATE.zip on your computer
  • Copy Hellcat’s Recovery Flasher (RECOVERY folder) to PSP\GAME folder
  • Copy the firmware (it’s an EBOOT.PBP file) you want to update to PSP\GAME\RECOVERY folder and rename it as follows:
    • If you’ve downloaded 3.71 firmware rename it to 371.pbp
    • If you’ve downloaded 3.80 firmware rename it to 380.pbp
    • If you’ve downloaded 3.90 firmware rename it to 390.pbp
    • If you’ve downloaded 4.01 firmware rename it to 401.pbp
    • If you’ve downloaded 5.00 firmware rename it to 500.pbp
  • Run Hellcat’s Recovery Flasher in XMB
  • Hellcat’s will now install custom firmware for your PSP

A few other things about Hellcat’s Recovery Flasher

What is the Recovery Flasher for?

  • Recover semi-bricked PSP (PSPs that can ONLY enter the recovery menu and little else)
  • flash *ANY* CFW directly to almost any other
  • Upgrade or downgrade your CFW. Supported custom firmwares are as follows: 3.71 M33, 3.80 M33, 3.90 M33, 4.01 M33, 5.00 M33.
  • Backup/restore firmware flash (not NAND dump)
  • Make and restore NAND dumps

FAQ

Can I use it to install custom firmware on my 5.50 ofw psp? No.
If you have a hackable PSP (check this guide for that), you can use pandora to downgrade your PSP and install custom firmware. If it’s not hackable. NO. Sorry.

Simple right? If you’re still having problems, specifically when installing the ChickHen hack, just post a comment on the ChickHen R2 installation guide. If you have comments or questions on the whole process, post here.

Have Something To Say ?

  1. Matt Hannan July 21, 2009 Reply

    sylv3rblade, you are a absolute gentleman. Followed your instructions to the letter (without Pandora) and now have M33-6 installed. Thank you!!!!!

    Is it worth my while installing GEN-A or GEN-B or will M33-6 let me do everything I need?

    Thanks again!!!!!

    • sylv3rblade July 21, 2009 Reply

      Hey congrats. If you’re looking for stability I suggest you install the 5.00 M33-6 patch.

      As for installing 5.50 GEN-A/B, do it if you want to access the PSN. As of the moment thought, 5.00 M33 is much stabler than 5.50 GEN-A/B.

    Hello there,
    Recently got my hands on a psp 1001. I don’t have a pandora battery however I do have a memory stick but no cable to connect my psp to the computer. If I was to get that cable, could I install 5.00 M33-6 using your instructions? Also, you said when you have loaded chickhen, do you mean after you installed it on your comp?
    Thanks

    • sylv3rblade August 3, 2009 Reply

      Yes you can but I would suggest sticking to 5.00 M33-6 if your PSP supports it or 5.03 GEN-A.

    i made my psp 5.03 ofw to 5.00 m33 using chicken r2 and CFW ENABLER. as u told me it is better to be wit 5.00 m33, rather than downgrading it to 4.01 m33.. NOW MY QUESTION WHEN I WANT TO CONVERT 5.00 M33 TO 5.00 M33-6 . USING THE UPDATE FILE. IT GIVES ME A MESSAGE ON XMB.. ITS ALREADY AT HIGHER UPDATE…HOW CAN I CONVERT IT TO 5.00 M33-6?

    • sylv3rblade August 7, 2009 Reply

      I thought you got it working? Yes, chickHen will run on ANY PSP model regardless of what motherboard you have installed.

      The only way for you not to be able to install chickHen is if you have 5.50 ofw as your firmware.

      Technicly u can, but keep ur psp hooked for better or try the Pandora Deluxe method, which is silvrbladenx8 comment in this article, Get pandora with no extra battery or memory stick. Its on atma Explorer, look it up. It’s good, but u need phat psp and ofw 4.05. U git 4.01 m33 from dat hack edition, but it might not work, its just trial and error.

    Nice guide syl!
    I’m a total newbie about installing FW, I was worried for days not to brick my psp before trying this. Then after I followed this guide, it worked! Although it confuses at some point. But overall, it’s great! I can play my psp with iso/cso again. :)
    Question, can I delete the files used for installing in my memory when finished? Thanks!

    Ownage!

    • sylv3rblade August 29, 2009 Reply

      Depends on what PSP version that you have. If it’s a phat or PSP Slim with non-TA-088v3 motherboard, yep, you can delete it. If not, just keep it so you can reinstall cfw if you accidentally turned off your PSP. :D

      Go MO :D

  23. prototype* August 30, 2009 Reply

    So if this not TA-088v3 its okay to shut down. But I don’t know if this is TA-088v3 how to identify it? And serial number starts with HE0. :)

      You’re trying to install a firmware version that isn’t supported by your PSP. I listed it on the important part :( You seemed to have missed it.

      Try 5.03 GEN-A or CFWEnabler instead.

    HEY THNX BUT I DID CFW ENABLER BUT MY SYATEM SOFTWARE SAYS THAT 5.03 MHU PLZ TELL ME WHATS THAT

  27. corix September 7, 2009 Reply

    after doing this things is it ready for the iso/cso games…. and what versions of psp do this cfw applies for.. or you just download the cfw of the same type of your psp version? or you could any of the cfw provided to any pap hackable version?.. coz i hav read on another blog the you still have to downgrade ur psp to 1.5 and upgrade again to be able to run iso/cso game.. sorry for d many questions.. but thumbs up for ur post.. i wanna learn to do this psp upgrading stuff.. more power n tnx

    • sylv3rblade September 7, 2009 Reply

      After you install this, yes, you can readily play ISO games. As for the cfw version, as shown above, you can pick which firmware to install, although I’d recommend 5.00 since it’s the latest M33 release.

      Now for the important stuff. This method only works on hackable PSPs. As for the need to downgrade, that only applies to the old method, using pandora, with the method I’ve posted, you just need to run chickhen and the hellcat’s recovery plugin.

      If you have any more questions, please feel free to post.

  28. corix September 7, 2009 Reply

    ok thnx.. but one more thing.. im watching on youtube same thing as this (http://www.youtube.com/watch?v=ipVkKmW7x7s ) … do i have to upgrade my version first to 5.03? or no need? coz 5.00pbp update is the same as 5.03?
    – as for the hellcat, i just have to copy the “recovery folder” to the psp/game right?.. together w/ the FW 5.00.pbp.. just in the same folder? so thats helcat eboot.pbp and 5.00pbp in the “psp/game/recovery folder” together…?
    – the update for psp3k i have done perfectly– quite simple…^_^
    – the update for CFW for hackable psp2k im still in questions, im afraid to brick one” T_T.. i might loose a 9k in just wrong move.. ^_^.. aniways big thankz…

  29. corix September 7, 2009 Reply

    for what i have watch in youtube… he updated he’s version to 5.03 first and do the chickHENr2 mod and updated the CFW lastly. which becomes 5.03 m33… what if i got version 3 or v 4 as the original firmware.. do i have to just update it w/ chickHENR2 and the hellcat directly?… or must update it first to higher version as 5.00 or 5.03 before proceeding to chickenR2? or if i have fw version 4.01 i just use the 401.pbp… or ANY HACKABLE PSP version will work on 500.pbp upgrade w/o the use of upgrading it first to 5.03?

    im sori..hope u still have the patient to get my point.. im a little bit confuse w/ CFW update… the psp3k is much easier but it bugs me about the reseting when the games just corrupts when the psp turns off or hangs up or lowbatt… hehehe patience…

    all in all nice guide… 2 thumbs up for you…

    can you help me?

    • sylv3rblade November 14, 2009 Reply

      Thanks :D. Here’s a few info for your current predicament.

      Since your PSP is unhackable, the only custom firmware you can install on it is those of the 5.03 variant, in this case, CFWEnabler, 5.03 MHU and 5.03 GEN-B. You can’t upgrade to a 5.50 custom firmware because it’s incompatible with your hardware so you’re stuck with 5.03 but don’t worry about it… I’ll explain in the end :D.

      As for being able to play Assassin’s Creed, it works on 5.50 GEN-D (the cfw that you can’t install) and 5.03 GEN-B (the cfw that you CAN install). So in short, just install 5.03 GEN-B.

    Hello,

    I just got a couple of questions. I have a psp 1002. IT has official firmware 6.20. The Date code is 5d. Can i install a custom firmware straight onto it or do i have to downgrade? another thing is that i’m getting a second memory how will this work with custom firmware?

    Also i just read that any ofw one psp 1000 is compatible with custom firmware does this mean i can install CWF on my psp 1000 with 6.20 OFW?

      You need to upgrade to 5.03 before running ChickHEN. It will work ONLY on 5.03

    I tried these instructions on a Slim V1 ta-85 v1 and it didn’t work, I think my PSP is a brick now. The only thing that wasn’t to the letter was tha the ChickHEN was for the official site not the links given here. At first it said to was extracting a .prx file and tried something and the check sum wasn’t as it expected. I went back to the main menu and tried again and it had more errors. I didn’t reload my flash save as it warned me it could be even more harmful. When I exited the program the psp rebooted its self, it came back to 5.03 and I went to chicken again, it did not not work and when the it rebooted after that its just black with a screen. I did make the batter a pandora and backup the nand and flash but I didn’t make the stick magic. I guess I need to get a card reader so I can make the stick magic and unbrick it? When I insert the batter it does turn on.

  71. Dead February 1, 2010 Reply

    and this is where I feel stupid because while sitting in my thinking closet I remembered hearing that pandora’s can’t normally power a system. Got it booting from the AC, now to magic stick it and CFW it!

    • sylv3rblade February 1, 2010 Reply

      Wait.. so you’ve managed to revive your PSP?

      • Dead February 2, 2010 Reply

        I wouldn’t say revive, I’d say I’m an idiot, I think it didn’t do anything it tried to unpack but didn’t correctly so it didn’t do anything but I had converted my battery to a pandora, which I had heard from someone else won’t actually run a system. So it booted once without noticing but when it booted again it noticed the battery is a pandora and it is looking to go into the special mode but I didn’t make a magic stick. If I take the battery out, boot from AC then it works. I’m trying to make a magic stick now so I can just pandora flash and be done with it.

    hi there, i have a problem here. 1st i checked my psp if it is hackable or not using ident and chickHEN. i thought i bought a psp 2000, the information given to me by ident is this,
    motherboard type: brite
    motherboard model: TA-090v1
    PSP version: Slim v3.0
    given the information form “is my psp hackable?” i thought this is psp2000. so i proceed to recovery flasher for a cfw. but when i run it, says its cant proceed because i have a brite psp. good thing it didnt brick. so my question is, do i have a brite psp3000 then? psp that cant be hacked? because i tot TA-090v1 is hackable. help. :) filipino here. :D

    hey thanks for the help.
    i bought the unit they say that they changed the housing of the unit making it 2nd hand and selling it at a cheaper price. you know what i think? the inside is a 3000 but the housing is a complete 2000. this one is refirbished. now im having problems. maybe ill just install 5.03genA is it?

    • sylv3rblade June 16, 2010 Reply

      What problems are you experiencing? If possible I’d recommend 5.03 GEN-C for compatibility.

  85. cline June 16, 2010 Reply

    actually the only problem here is the cfw. there is no cfw when i bought it. so when i get to your site, first thing i did was to check the hackability, then the chickHEN and PSPident for the motherboard (your posts works well, the problem is my unit) then i ended up knowing that this unit is actually BRITE from the inside but a complete SLIM LITE from the outside (even the box). such a headache since i get hold of this. now ill just go with 5.03 genC for cfw. thanks for all the help!

    Hi,

    I have spent a lot of time reading whether my psp is hackable or not. I read that mine is fully hackable. It is a PSP-2003 (UK produced), currently having 5.50, most probably (OFW) – but not sure. The interesting thing that shows me that it is hackable is because the DATE CODE is 8B, with a SERIAL: HB2777xxx, it is a second hand the the guy before me may have updated the firmware to 5.50, so it is a guess to me whether this is the official.

    Now, I need help: I would like to use PSPTube and as an extra be able to play UMD backups. I do not have a Pandora battery nor Magic Memory stick. I would like to know what to read to get some custom firmware and which one exactly. What is the difference between the 5.50 GEN-A/GEN-B/GEN-D? Which one do I need? Should I downgrade to 3.90 M33 – I read it is possible? Can I install a 5.50GEN-A to my (possibly) OFW 5.50 and where do I get it from? Can I do it without a Pandora battery?

    Thanks in advance! I really appreciate your time spent here.

    Hi,

    I have a fat psp with chkHEN R2 enabled. I followed your guide to flash firmware 500.PBP using Hellcat’s Recovery rflash160.zip. My psp now say System Software 5.00 M33-6. However, I cannot install Prometheus-4 or play any games. The games and Prometheus software show up normally in the memory stick. However, when I X on any of them, the psp just reboot and shut down after few seconds. Please help.

    Thank you much.

      That sounds like a bad flash. Either reinstall 5.00 M33-6 using Hellcats or upgrade to 5.50 GEN-D3 then install the prome-4 build for your chosen firmware.

  108. roge April 3, 2012 Reply

    Hi sylv3rblade,

    Thank you for replying. This is what I did:

    . I can only install CFW 5.50_gen_A and 5.50_gen_B and 5.50_gen_B2. However, I could not get 5.50_GEN_D3 to be installed, the error message was “mso:/550.PBP not found on root of your ms”.

    . Hence, I reflashed back to firmware 5.00 M33-6 (via Hellcat’s rflash165.rar) and stuck with the same problem from the beginning.

    I short, my choice now is either firmware 5.50_gen_A or 5.50_gen_B or 5.00 M33-6. And none of them will let me play any games, even homebrew. Any suggestions will be appreciated.

    Thank you much.

    • sylv3rblade April 4, 2012 Reply

      The error you experienced with 5.50 GEN-D3 can be resolved easily actually, just check if you installer has put the 550.PBP on the root of the memory stick.

      As for CFWs not being able to play games, press select and check what the UMD Mode is set to.

  109. roge April 4, 2012 Reply

    Hi sylv3rblade,

    Thank you. That was a great tip. I missed the 550.PBP file at the root. The 5.50 GEN-D3 was installed successfully.

    Next step, after several tries, I found out that the SEPPLUGINS folder was the reason that stopped me from playing games and installing prometheus-4. I don’t know how it got there, but after deleting it, I was able to install prometheus-4 and get on with the games. :-)

    Thanks a lot sylv3rblade for your time. You’re a real life-saver.

    • sylv3rblade April 5, 2012 Reply

      Not a prob.. It’s probably one of the plugins that got loaded via the seplugins folder.

      In any case, enjoy and I hope you’ll stick around :).
