Have Something To Say ?

  1. venjuliene_corpuz Venn August 25, 2011 Reply

    sooooooo……….. should I update to 6.60 Pro B9? or 6.35 Pro B9??

    still at 6.35 right?

    • atmaxplorer sylv3rblade August 26, 2011 Reply

      If you are experiencing problems or simply want the latest code running on your PSP then yes, you should upgrade.

  2. venjuliene_corpuz Venn August 26, 2011 Reply

    uhm… so based on stability, which is better? 6.35 Pro B9 or 6.60 Pro B9?

    • atmaxplorer sylv3rblade August 26, 2011 Reply

      They’re fundamentally the same. Just pick which firmware you’re closest to (i.e., if you’re on 6.35, stick to that)

  3. hexagon_tj Jeffrey August 27, 2011 Reply

    how about the other folder? where can i put that? “CIPL_Flasher”

    • atmaxplorer sylv3rblade August 27, 2011 Reply

      That is meant for hackable PSPs only

      • hexagon_tj Jeffrey August 27, 2011 Reply

        i will also copy the “CIPL_Flasher” in to game folder?

  4. venjuliene_corpuz Venn August 27, 2011 Reply

    oh i see… guess i’ll have to stick with 6.35 then. Gosh… all these updates… i wish Sony would just release a final cfw for the psp and then the pro team releases a cfw with a perma patch.

    • atmaxplorer sylv3rblade August 27, 2011 Reply

      Well 6.60 was released in preparation for the HD Remakes of PSP games on the PS3 so it’s a benefit for people who have both systems

  5. venjuliene_corpuz Venn August 27, 2011 Reply

    oh wow. that’s just cool. And here i am wishing I had a PS3 :(. Though i really am worried about purchasing one and then after a year or so I get a YLOD (same goes for the XBOX 360 which has RROD).

    I do hope that the Vita (which has great graphics) won’t be experiencing those kinds of problems… coz at least the Nintendo Wii don’t.

    • atmaxplorer sylv3rblade August 27, 2011 Reply

      From experience and the stats, the PS3 is generally robust (even more than the 360). Like with any console, remember to keep it clean.

  6. wooncinghsian WOONCH August 28, 2011 Reply

    Is it compatible with PSP 3000?

    hi pahelp po, nagccrash yung psp pagka run nito. 🙁

    • atmaxplorer sylv3rblade August 30, 2011 Reply

      What’s your current firmware? San sya specifically nag-crash?

      • ohohnero Nero August 31, 2011 Reply

        6.20, pagka run po ng updater, then install cfw, pag babalik na ng xmb, mag hang and crash na. 🙁 lahat ng ‘updater’ magcrash lang eh. tnry ko mag 6.60 tapos downgrade to 6.20 para daw i reset yung flash? pero pagka ‘accept’ sa downgrader, mag hang lang at mag-off. :((( kahit nga po mag ‘exit’ lang from the downgrader, crash parin.

        • atmaxplorer sylv3rblade August 31, 2011

          Anong current OFW mo ngayon? Just take note, hinde gagana ang installer kung hinde ka nasa tamang OFW (i.e. 6.20 PRO-B9 needs 6.20 OFW)

        • ohohnero Nero August 31, 2011

          6.60 ako now. 6.20 ang ofw nung nirun ko 6.20 pro-b9, pro-b7, tn hen-c. all led to a crash

        • atmaxplorer sylv3rblade August 31, 2011

          Sa 6.60 nagkakaroon pa rin ng crash? Na try mo magpalit ng memory stick?

  8. pentheraphy Anonymous September 10, 2011 Reply

    Correct me if I’m wrong, but does this mean that ANY PSP console can upgrade to this custom firmware as long as it’s running any of the aforementioned OFW? No risks and such?


    • atmaxplorer sylv3rblade September 10, 2011 Reply

      Well there is a slight risk because it’s writing onto the PSP’s flash memory but overall, yes, the process is safe.

    is it possible to install 6.35 PRO B-9 if i have 6.35 PRO B-8 and how?

    • atmaxplorer sylv3rblade September 20, 2011 Reply

      Upgrading is easy. Just revert your PSP to OFW, replace the installer files with the new ones and run the installer again.

  13. acromion acro September 27, 2011 Reply

    Hey I’m running a psp 1000 on 5.5 prometheus 4. Is there any benefit in updating to LCFW 6.xx and up?

    • atmaxplorer sylv3rblade October 16, 2011 Reply

      Since a lot of the newer games don’t work natively with prome-4, you get the advantage of no longer waiting for a patched version for them.

      • plumpcherry O.o October 17, 2011 Reply

        In that case then I will update both my 1000’s to 6.xx. Thanks! But btw are there any other potential downfalls on the other hand?

        • plumpcherry O.o October 18, 2011

          is 6.60 pro-b9 a cfw or LCFW, as from what i see it seems that i have to reinstall it everytime i turn off my PSP (not put it to sleep)?

          Also, if what I’ve said above is right, then would you suggest the next best PERMANENT CFW for a PSP-1000 please (or a LCFW, if there is some way i can make it auto install each boot up)

  20. sonuch Sonu October 16, 2011 Reply

    Is this hack permanent for 3k models?

  21. ahg_osment Sebastian October 17, 2011 Reply

    Hello, first up, sorry for being a n00b and any obviously n00b questions :p
    I am using a PSP-1002 with CFW 3.60 M33-5… I’m fairly sure it’s permanently hackable as the CFW I have on there now never needs reloading.
    I am considering upgrading the CFW (don’t know what version I should go for) so that I can play PSOne FF7 epub’s that I’ve got.
    At the moment, the game works fine for about 2 minutes, cutscene works, game plays, but as soon as it tries to go into the first fight scene by the train, I get graphical glitching and the system freezes.

    Can you please suggest a CFW I should go for, and anything I need to keep an eye out for updating from 3.60 to whichever I choose?
    Thanks in advance,

    • atmaxplorer sylv3rblade October 18, 2011 Reply

      Hi, I would suggest going thru the whole dummy’s guide to catch you up on what’s new with the scene and things that you need to know.

      • ahg_osment Sebastian October 19, 2011 Reply

        Yeah, I had already done all of that, been back and forth all over the site reading all about it, I just wasn’t sure which firmware to settle on.
        In the end I went for 5.50 GEN-D3, which is working like a charm.
        Thanks very much for your help and your awesome site =D

    i hav pro b9 6.60

    plz replay asap

    • atmaxplorer sylv3rblade October 19, 2011 Reply

      Does does happen to all games you want to play? Also try using the inferno driver, it has better compatibility throughout the PSP games

  23. macky_mk1 macky October 20, 2011 Reply

    one of my friends accidentally updated his psp to 6.37 during using a UMD. what can you recommend downgrade to 6.20 or upgrade to 6.39 or 6.6

    • atmaxplorer sylv3rblade October 20, 2011 Reply

      I would recommend downgrading to 6.35

      • makcy_mk1 makcy October 23, 2011 Reply

        why downgrade to 6.35, i already read the downgrade guide which you can download up to 6.20. Are there any big issues when downgrading to 6.20. or there a specific limit up to what firmware.

        • atmaxplorer sylv3rblade October 23, 2011

          For now the soft limit is 6.20. Only hackable PSP’s can be downgraded beyond that point. Also some PSP-3000‘s can’t be downgraded to anything below 6.35.

        • macky_mk1 macky October 24, 2011

          ah ok, for PSP 3000 it is safer to downgrade up to 6.35 due to report having difficulty downgrading beyond that. But can i say if i have PSP 2000 TA-088v3 i can safely downgrade to 6.20?

        • atmaxplorer sylv3rblade October 24, 2011

          Yes, psp slims are safe.

        • macky_mk1 macky October 24, 2011

    Hello, at first, let me give details on my psp 2000 slim, running 5.03 HEN with TA88v3 motherboard.

    I want to upgrade my firmware due to some newer games not really supported on the 5.03 firmware. So, I did google and found out that 6.20, 6.35, and 6.60 are all suit my psp. Here, it make me confuse because I don’t know how to choose, which one better for my psp.. So, I want to ask for suggestion..

    1. PSP 6.35 Pro-B5 LCFW
    2. 6.20 Pro-B5 LCFW
    3. 6.20 TN-D Hen
    4. 6.60 PRO-B9 LCFW

    Those are the thread that I read and know these firmware..

    • atmaxplorer sylv3rblade February 13, 2013 Reply

      All 6.xx iterations are now up to the C2 version (6.20 PRO-C2, 6.35 PRO-C2, 6.39 PRO-C2, 6.60 PRO-C2) which you can install by following the instructions here. As for which version to install, I would suggest going with 6.60 PRO-C2 since newer games might require a newer firmware.

      If you need a guide on custom firmwares, etc, then head to my guide here.

      • free_update32 Jason February 15, 2013 Reply

        I found out that there got 6.20 pro-c fix3. And is this the latest?

        • atmaxplorer sylv3rblade February 15, 2013

          The C2 release is newer since the fix3 patch remedies the problems with the original Pro-C release.
