3.50 Downgrader FAQs
Written by Fanjita    Monday, 02 July 2007

Image We've had a lot of questions about the v3.50 downgrader.  Here's an attempt to clear up as many of these as possible.

  1. Can I downgrade without reading the readme guide?
    Yes, if you're feeling brave and stupid.  We write the readme to protect you from common problems and mistakes during downgrading.  Please read it first.

  2. Should I do anything before I downgrade?
    Apart from the instructions in the readme, the only other thing you might want to do is to backup your Lumines savegame, if you want to preserve your profile.  Just back up any folders from /PSP/SAVEDATA with the word LUMINES in the name, then copy them back once the downgrade has completed.

  3. Can I still play Lumines after downgrading?
    Sure.  Just remove the exploited Lumines save data from /PSP/SAVEDATA - either just delete it, or replace it with the backup you made before downgrading.

  4. How do i downgrade a firmware version less than 3.50?
    Simple.  Just upgrade it to v3.50, then do the downgrade.  Don't upgrade via Network Update though - that will install v3.51, which won't work.  Just grab the 3.50 EBOOT from the location given in the downgrader readme file.

  5. Which idstorage keys are altered by this downgrader?
    This downgrader uses the latest idstorage hack for TA-082+ motherboards.  That means that it only modifies key number 5, which means you won't suffer from most of the issues that affected earlier downgraders.

  6. When will the v3.11 stuck firmware fix come out?
    Some time soon.  We're all very busy, and will get to it as soon as we can.

  7. Will there be a version that doesn't need Lumines?
    No. Not for a long time.  Lumines is a good game, and even with all the price-jacking it's not too hard to get hold of.  We did a lot of hard work to bring you this downgrader, it's not so much to ask you to make a bit of effort to track down Lumines.
  1. When will there be a HEN? I don't want to downgrade.
    There already is a HEN, it's included with the downgrader.  It should be just as compatible as the v3.03 HEN.

  2. When will there be an eLoader then?
    As soon as we can find time to get around to it.  We appreciate that some people don't like to downgrade, and do want to do something to support you too.  It just takes a little time - please be patient.

  3. Which versions of the PSP does this work on?
    It works on any currently-available PSP.  The region, model number and colour does not matter.

  4. Which versions of Lumines does this work on?
    It works on all US, EU and JP versions of the original Lumines game, including Platinum, Greatest Hits and The Best versions.  As far as we know, the Australian and New Zealand versions are identical to EU or US, so those should work too.  It does not work on Lumines II,  and it does not work on Lumines+ (that's for PS2 anyway, dummy! Wink )

  5. Does this work on Japanese Lumines? When will it work?
    Yes, it does now! Grab the updated downgrader .

  6. Does Noobz need a copy of Japanese Lumines?
    No, thanks.  We now have the UMD thanks to the help of Daimaou and BDIGITAL.

  7. Does this work on Korean Lumines?
    Yes, it does now! Grab the updated universal downgrader .

  8. Does Noobz need a copy of Korean Lumines?
    No, thanks.  We now have the UMD thanks to the help of GucciPAPA (and kind offers from many other people).

  9. What do you think about people selling downgrader services?
    If it's a reasonable price, it's not so bad.  It would be nice if they would acknowledge the original authors with a donation, however.

  10. What do you think about people selling  Lumines at high prices?
    They are scum, pure and simple. We attempted to help the community with a game that was cheap and plentifully available.  Those who are exploiting the community with high prices are ruining all that, and they are nothing more than selfish bastards.

  11. Which version of the 1.5 firmware should I use?
    All official versions of the v1.5 firmware are identical - you can use the North American version (using the link in the readme) on any PSP, without any problems.

  12. What do I do after I've downgraded? I'm confused!
    The world of homebrew awaits.  There are some simple guides on the PSP Homebrew site that should get you started.

  13. Lumines won't start now on v1.5 firmware.
    You need to delete the exploited Lumines savegame from /PSP/SAVEDATA.  Then it should start normally.

  14. The downgrader complains that it has a corrupted update.pbp file.
    We're not quite sure what causes this.  Try following the instructions again, being careful to follow them exactly.

  15. The downgrader complains that it can't find update.pbp
    Probably Windows has renamed it to update.pbp.pbp. Try just calling it 'update' rather than 'update.pbp'.

  16. Does this exploit work for other games?
    No.  Although other games may look superficially similar, their code is different and this exploit cannot be ported directly to them.  You need to accept that you need Lumines, sorry.

  17. Where can i download ISOs?
    Don't do that.  Really.  Just buy the game.  You can always convert it to ISO yourself if you really need the battery and load-time benefits.
  18. Can you recommend some good homebrew?
    Take a look at the PSP homebrew database for a slightly out-of-date, but still useful, list.

  19. I keep copying MS_ROOT but it doesn't work?
    You're copying the MS_ROOT folder, but you should be copying its contents.  Re-read the readme instructions.

  20. This downgrader isn't enough for me. Release another one. Now.
    No.  If this downgrader isn't good enough for you, that's tough.  We put a lot of effort into it, and can't afford to keep doing that to meet your whims.
Hope that helps.  Any more questions, please add them below.

  lumines 2 is also for psp and if nobody at the company noticed the "weakness" (hint being no patch) is it not possible that lumines 2 may have the same or a similar vulnerability? good luck with the eloader can't wait!

p.s. i haven't downgraded before but i know that the frimware files have things you must read before you upgrade maybe you should put a copy of the readme in there too.

  If any one was stupid enough to downgrade to 1.5 with lumines. Then upgrade to 2.60fw Like i have then you have noticed you cannot upgrade to 3.5 again to use the lumines exploit. However you can upgrade to 2.71fw then down grade to 1.5fw again. I recommend then upgrading to 3.40 oe-a in remembrance of Dark Alex's work.

.......................CAn SOMONE HELP ME HERE!!!!!!?????

Yes, I suggest that you use those they are cool, but remember NOT to backup your flash0 that will brick your PSP. Just go to recovery mode, select that you want to connect your flash0 to PC and delete EVERYTHING inside flash0:/ after that put the new icons there and restart. If it doesn't work you have done something wrong and your PSP is now a brick congrants. (That's what you get not asking politely but screaming around)

But hey cool, I'm gonna pick up my Lumines today from the local Tilt Player's Shop but I'm not gonna downgrade just yet. You know why? Sony blocking upgrading over 3.30!

  Another question : will you release some technical information about the exploit (extract from lumines's code vulnerable to the buffer overflow...)?

Squirrel from the Netherlands said:

  The brightness bug has nothing to do with corrupted keys. It is caused by changed display hardware. So even when using this corruption-free downgrader, you can still have the brightness bug in your PSP.

  i'm new to downgrading. I read the how to file and its pretty straight forward... thanks. I just want to know if i still need the lumines game after the downgrade is completed? I can't find a store that sells it here in winnipeg and Im thinking of renting it. thanks in advance for the help

  I'm abit confused. HEN is not the same as a downgrade, right?
If you use HEN you can always go back to the original PSP firmware, right?
Doing a hardware reset will bring you back to the original firmware?
Can somebody tell me how to do a hardware reset?

  does tha downgrader work wit GTA LSC? coz iz like impossible to get lumines at a cheap price smilies/grin.gif

[MOD EDIT: There will probably never be any exploit for GTA for firmwares above 3.03. Sony did a better job of fixing it the second time around.

My psp is messed up somehow, so i want to make sure it will still work:

At the part where it says to press r if you do not want to continue, what would happen if r was already pressed when that screen displayed, and held down (which my psp does for some reason).

  umm...

So, I was gonna try to upgrade to the dreaded v3.1, and wait a year, just playing my own games that I bought for it, but it won't upgrade past v2.60. Any suggestions? smilies/undecided.gifAnyone? Open to a way to get the emulators back on but I keep getting the error message "the system configuration of this PSP system does not appear to be correct. The Update cannot be compleated." -For the update and "The game could not be loaded" - Then a number code for games and such. HELP! smilies/cry.gif

  Hey, this is probably the only case of this happening. But i kinda spilled dr pepper in my PSP. BY ACCIDENT!!! But anyways the psp wont read UMDs anymore and so i cant use the current 3.5 downgrader. And im too cheap to buy a new PSP, so i was just wondering if anyone would work on one without the lumines. I know theres more important things, but im bored as hell and all i can do is listen to music and play sony demos...

Helepon said:

  I can't believe people here are talking like Noobz owe them their work. Have a little gratitude...

So anyways, congrats on the release. I've got a bit of a problem though, I was wondering if anyone else experienced the same thing. Basically, I've upgraded to 3.50, and after having followed the instructions exactly, Lumines simply starts up as normal. I've tried default settings and formatting. The only variable I can think of is the fact that I did nothing with the other two directories in the .zip (because nothing was said about them in the how-to). Have I missed something?

Thanks for any help.

[MOD EDIT: You probably copied the files to the wrong place. Reread the instructions, and check whether it's possible that you have a patched Lumines]

  Thanks for your hard work guys. Much appreciated.

I only wish there were more games that could be easily exploited. Lumines magically sold out in every store around Houston, TX within a day of your release. I was running around a dozen stores last week - the employees everywhere were saying "weird, your the 7th person today looking for Lumines". They couldn't understand why Lumines II wasn't selling. I told them "It's because The Blak Eyed Peas suck."

Oh well, ordered it online at 4x the price. :\ Hopefully it will arrive next tomorrow.

  Hey I've tried to downgrade my PSP with the v3.50 universal downgrader. I've followed all steps which were written in the readme but nothing "special" happenend when I load Lumines. It just starts up the game, the screen color doesn't change and he doesn't reboot it self.

The steps that I have token:
-copy the contents of MS_Root to the root of my memorystick
-placed UPDATE.PBP in drive/psp/game/update
-load and run lumines

Could someone help me out, thanks already!!!

  Looks like my comment got cut off. If you got an error "corrupted data" when trying to copy the 3.5 update (if you were using a version lower than 3.5 and had to upgrade before you could downgrade) here's what you need to do. Make sure the EBOOT file you're using does not have the numbered prefix, but just says "EBOOT.PBP" If there are any numbers (ex. 12345-EBOOT.PBP) delete the numbers so it's just "EBOOT.PBP". Now it should work. smilies/cheesy.gif

  New user here .. please be gentle: smilies/smiley.gif
I recently picked up a used PSP that has 2.80 on it w/Lumines - and it is a TA-082 motherboard. I've read and read and can't find "explicit" instuctions on how to upgrade to 3.50 (and I don't want to brick it either). Can I just upgrade to 3.50 from 2.80? or do I have to upgrade to something else first? In the read me there's a link to upgrade to 3.50 from 3.10-3.40, but nothing for 2.80. Regards, and thanks in advance.

  Ok. I have been trying literally everything for the past 3 days, and working at least 6 hours/day for this. I upgraded to 3.50, and got 3.50 HEN version. I got the UPDATE.pbp right, but for some reason that only works if theres UPDATE.PBP and EBOOT.PBP in the folder at the same time. Then i start to X.YZ Update, and it says DATA.PSP could not be found - Check if UPDATE.PBP is a valid .pbp file.
Nobody has been any help wherever i go, and no solution seems to work for me. If i change it to anything else than having UPDATE.PBP and EBOOT.PBP in the same folder, i get a Corrupted Data Symbol. Ive been working on this night and day, please somebody actually help me already!

  Just want to say many thanks.

I just bought a PSP a couple of weeks ago and was lucky enough to find the Lumines game at Toy R Us for 20- instead of eBay at 45 .

Instead of being selfish and buying the last 2 copies on the shelf so I could take advantage of a little kid out of their milk money, I left behind in hopes that who ever buys the game will actually play the game like myself.

Once again, many thanks from this PSP Newbie smilies/cool.gif

I had waited so long for the 3.11 downgrader and the screwed myself over. SO I ASK YOU PLEASE HURRY ON A 3.11 FIX FOR THE PSP BECAUSE I WAITED SO LONG FOR 3.5 downgrader and now I have to wait more.

  My friends, you make me very happy with discovery that I find helping! smilies/grin.gif

But if you could be more direct on what damage is caused to a PSP that would be of the up most kindness of you to do so.

Also, I find that using a exploit from Codebreakers is ok if you have no clue what to do with your Lumines game?
August 31, 2007


  I'm stuck on 3.11 can you make the fix so we can update again so I can update to 3.5 the downgrade to 1.5 or make a downgrader for 3.11 will you please help. Hurry

  Question: I have a version 2.81 PSP. Can I upgrade to 3.5 and then use the Lumines to downgrade? I don't want to look for GTA LC and thought this would be a good alternative. Please can someone confirm it can be done? Thanks.

  smilies/cry.gif I'm so sad because it won't work for me. I have lumines 10002, and I already downloaded HEN and got MS_ROOT folder and dragged it into my psp as a separate folder. I also did the EBOOT/UPDATE.PBP thing. I have a macbook, and I don't know how to unzip it. I need serious help SERIOUSLY. Everytime I try, Lumines just goes straight to the game, and I end up playing.

  Thanks guys, great website, I have a PSP bought 2 years ago, with 2.81 firmware, but looks just like the slim PSP. However, it said here that it can't run firmwares below 3.60, what's wrong with my PSP then? It comes originally 2.81... I downgraded to 1.5 then upgrade to 3.40... after used it for 2 yrs, all the keys suddenly function crazy... should I reupgrade again?
