    Hey there guys, I was just curious for the PSP 1000 release of 6.38 ME v2 how is the 1.50 kernel addon compatibility with it? Will homebrew for 1.50 run on it without installing the addon? Or is the 1.50 kernel addon still necessary?
    Thanks again for any reply’s.

    cwcheat works confirmed

    can someone please update the xmb icon maneger and pspconsole plugin to work with this

  • Fenrios Senju

    Never mind what i said earlier, it was my html_viewer plugin and my cxmb for M33- 6 that caused the black screen on rebot. All i had to do was load the recovery menu and disable them and it works like a charm All i have to say is THANKS!!!! NeurON for giving me this awesome gift i appreciate not having patch a damn thing!!!! ( no iso patching is required anymore, i tested it on god eater Burst) so hellz yeah and it makes my emulators run faster oh man


    I`ve updated my FAT PSP with 6.38 V2. But with no luck. I got 80020148 error on Peggle, Patapon 3 & God Of War. I tried different drivers but… Any suggestions? Flash1 & Flash2 are formated. No additional plugins.


      also – ISOs are unmodified.

    Everything turned to run! It`s AWESOME. Except PEGGLE. Seems like there`s a problem running PSN rips,


      One more bug… I wasn`t able to load savegame for patapon 3.

  • Adraymus

    Is it possible to make a pandora battery when 6.38 me CFW has been installed. When I had 5.50 GEN there was a settting in the VSH that allowed this to be done.

    • Fenrios Senju

      Naw you can’t but if you go download psp tool from downloads section on here you can make one pretty easy it takes about 5 minutes. Simply put the 5.OO EBOOT in the root of yer mem stick and rename it to 500.PBP and then run psp tool on your psp from the game section and go to memory stick options then choose create magic memory stivk and choose ddc8 and when it runs it’s gonna ask you near the end to change battery serial, choose yes then hold the left trigger( trust me the left trigger is the best button to choose) then you’re done. You’ll now have a mms and a pandora batterry woot

      • Brandon

        i was just wondering if when you pandorise your battery it can be changed back to normal and does the magic memory stick still work as a normal memory stickor do i have to get a new one. sorry about the really noob questions.

  • Jhaycee

  • Katx

    Is there a way to change my firmware to this after upgrading to ofw 6.38?

  • PSXMan

    Great CFW and all but I switched back to 5.00M33 to play PSX games again, if you don’t play psx on psp then this is the best cfw out there, I’ll come back to this one when it has psx support.

    • Anon

      This does have PSX support.

  • lost

  • nis

    game categories light is freezing at sub folder option
    does zero rco patcher work with this

    • maxxie

      That happened to me. I think the problem might be one of your plugins. The problem for me was Bookr and it wouldn’t load the game menu at all.

      • nis

        nope i dont think so game categories light is always freezing at subfolders
        even when other plugins are disabled

      • neuronFAN

        i have psp 2004, with 6.37 OFW, is there a way i can upgrade to 6.38 CFW?? i dont have pandora battery and mms atm.

    • free marc emery

      if plugins arent the issue then boot into recovery menu, go to configuration, make sure hide pic0/pic1, network update, version txt,skip sony logo, hide corrupt icons, hide mac adress, and fake region are all DISABLED, then reboot. it should work fine after that, at least it did on both my 1000s one with me the other with me-2

      • nis

        yeah it works but life without plugins???
        i would rather deal with the freezing bug
        i own a psp phat does this bug occur on a slim

  • nis

    • Fenrios Senju

      You gotta open his vsh men, select usb mode flash 0, then connect his psp to his comp and go to the folder vsh/etc/version txt and change the 9.90 to 5.00 then save changes and exit, disconnect psp from comp and run me2 installer again and it’ll work

    • xXRagnarokXx

  • DuLe22

    What’s the difference between 6.38 ME v2, CFW 6.20 PRO-B5, and CFW 6.35 v21?

    • cyberangel22k

      Try them. First 6.20 PRO-B5, then Update to 6.35 v21, you can also try 6.35 PRO-B5 on 6.35 v21 (that’s my current FW so i can switch between PIL and Inferno mode), then update to 6.38 ME-2. You will see their differences.

    • cyberangel22k

      PS: you should have a pandora handy so you can easily downgrade abck if you don’t like it…^^

    • cyberangel22k

      PS: you should have a pandora handy so you can easily downgrade back if you don’t like it…^^

  • hitman

    @fenrios thanks alot!!!!!!!!!!!!!
    it worked perfectly!!!!!!
    btw what country are u from????

    • Fenrios Senju

      I’m from the US. The reason it was on 9.90 is to prevent accidental ofw updates if you don’t have a pandora lol

  • Dagz

    okay, so i updated to this from 5.5 prometheus. only problem is that it doesnt seem to work. System Information shows 6.38 (not “6.38 ME”) after upgrading, L+Cold boot does nothing, Home+Cold boot same too. It does turn off all of at a sudden at random when i do either of them. no plugins installed.

  • neuronFAN

    i have psp 2004, with 6.37 OFW, is there a way i can upgrade to 6.38 CFW?? i dont have pandora battery and mms atm.

    please help =(

  • Ken

    ok my current slim psp has 5.00m33. If i was to update to one of these new firmware, which would be the safest, best, and most stable firmware to go to that would let me do everything i do on m33. Oh and how and what do i need to do before i do this?

    • Fenrios Senju

      Try using the 6.38 ME cfw’s out. I’m using 6.38 ME-2 for the psp phar and it rocks cuz of the ability to run freshly ripped backup games without the need to patch, it has the m33 iso driver, sony np9660, OE isofs, and me driver. It will be able to access psn when it comes back online apnd running the 6.xx kernel makes games load faster and run more smoothlt in addition to making emulators and etc run faster due to the improvements in memory stick handling in the 6.xx kernel so try 6.38 ME if you have a pandora, if you don’t download psp tool 1.00 and make one from your psp just incase u don’t like it and wanna change back. Sure it’s not all hoppef up on plugins like m33 cuz it isn’t fxckin ancient as fxck, no offense to dark alex but if you want clean, stable iso loading, psx loading on legit latest cfw then try 6.38 ME-2

      • John Jason

        I need help Fenrios Senju, I’ve upgraded my psp 2006 from 3.71(I think) to OFW 6.38 and now I can’t play the games I used to play before. Can I downgrade it back to 3.71(or other CFW like 5.00)? please help me, thanks!

      • YoJoe

        Hi… ok I have same question with Ken… I haven’t updated my PSP2k’s CFW for a long time now… currently running with 5.00m33-6…. if I got it right, I may need to install 6.38 ME before I can do 6.38 ME-2?? OR can i bypass that so I could install 6.38 ME-2 right away as you have said, this would be the cleanest, much stable, efficient CFW upto date…

      • YoJoe

        yay… ok so 6.38 ME is a Sony OFW… ok… totally understand now… my mistake… yikes… i do not own a pandora kit… guess i just need to stay with this CFW for the mean time

  • DuLe22

    I tried 6.20 PRO-B5 on my 3001 and it works great, will the other ones work as well?

  • Popsloader

    anyone get popsloader working on this?
    I get the “Loading Playstation bios” screen then it hangs and turn off, forcing me to restart my psp.
    I’m trying to play FFVI.
    Any help?

    • free marc emery

      wow, spam masta.. did you even search google or youtube before you posted the same thing 12 times? i swear noobs get lazier everyday :/ search for pre made 5.00 m33 magic memory sticks online then get hellcats signed pandora maker, and assuming you have the first psp 200x mobo (you /were/ on 3.71 lol) itll soft mod your battery into a pandora one, when your done flashing just change it back to a normal battery. after which i would suggest upgrading to 6.38 me-2, it slays m33 if you dont care about plugins atm. if you have one of the mobos that blocked writing to the batteries eeprom then you need to either buy a pandora or get a friend with a modded psp 100x and get him to temporarily soft pandora his battery and let you use it.

      • John Jason

        thank you very much! Godbless you! :D

  • Fenrios Senju

    People if you don’t follow instructions you’ll end up with ofw!!!! You have to take the official update file and rename it to 638.PBP and put it in the same folder as the eboot in release638me2 or whatever and rename that folder to UPDATE!!!! If you run the installer and you don’t start with a black screen with white letters you have failed and will end up with ofw if you continue. You must do what I said if you want, i’ll send you the folder to put on your memstick just tell me your email name and i’ll send you it within about 3hrs that’s when I get outta school today, and I’m not a little kid I’m a senior in high school who’s been installing cfw’s for people and gettin paid. Honestly it ain’t hard to install cfw but people just aren’t as tech savvy as they used to be….
