Its not kxploited then, if you want you can update to OE then run it from there cause it does not need to be kxploited.

But its up to you. Look here

I used the kxploit tool. It was very simple and it created the folders on my memory stick, like you said.

But when I tried to run the program on my PSP it says:

------------------------------
The game could not be started.
(80020148)
------------------------------

I tried a few times and I did a cold boot of PSP too, just in case. I originally tried by using the memory stick in the PC but I also tried with my Sony Walkman USB cable. But I get the same error no matter what.

This is frustrating.

[Brad]

Just update to OE if you don't see any errors. If anything comes up you can always run it latter straight from OE.

I do not know if there are any errors or not because I cannot get IdStorage Fix to run. I get the 80020148 error every time.

I'd rather not update to OE unless I have to, because my goal is to go back to official firmware. Of course, if that's the only (or safest/best way) to do it then that's what I'll do. But I'd prefer to check for the problem and fix it in 1.50 if I can, because there are less steps and it seems simpler - at least to me, but what do I know!

So, why am I getting that error? Do I have a problem? Or is the program incompatible with 1.50 or something.... thanks for your patience.

[Brad]

You can always go back to official firmware from OE if you want.

I ran kxploit on the eboot Try This

open and copy to X:/PSP/GAME

I tried it but I got the same exact error. Is it possible that this program is incompatible with 1.50? When I tried KeyChecker I got the same error - but was later told that it only runs in OE.

If there is no easy way to check and/or fix my keys in 1.50 I guess I'll have to upgrade to OE to check/fix and then go all the way back. That should be fine, right? Would 3.02OE-A with the built in "flasher for recovery" be the easiest upgrade with the intention of going back?

I'll just wait a bit to see if there is an easier way first... like I said I just want to get my keys restored and go back.

Thanks again for your help and patience.

[Brad]

You can update to 3.40 OE-A if you like Install Guide

From the sounds of things your keys seem like there fine. But once on OE run the program and if nothing comes up just stay on OE or let it fix the keys and stay on OE. Either way you will be going to OE.

Ok. Thanks! That's what it sounds like I am going to do.... but like I said I am just going to see if I can't find an easier 1.50 solution first.

This is probably a stupid question, but why do you think the keys seem fine? I was under the impression that they are probably corrupted because I used the downgrader with "idstoragechange"?

Once I am on OE, if my keys are either uncorrupted or fixed, I can still downgrade to 1.50 and then upgrade to any official firmware without any issues if I want to, right? Would I be as good as new?

[Brad]

Cause you have not told me you have seen any basic errors yet of the PSP no functioning right. So it seems like its ok.

Once at OE I recommend staying there cause OE is a very nice custom firmware, but if you want you are correct downgrade to 1.5 then go to any official update you want.

And all TA-82 - TA-86 PSP's have to run the idstoragechange when downgrading for the first time.

[|-Anubis-|]

corrupted keys don't really interfere with the downgrading process.

They mostly affect things like the screen brightness button working incorrectly.

I have no had any errors, except for the 80020148 one when I tried to run those programs, but I have not tried to do anything except for that (both of my UMDs require 2.71, there is no browser in 1.50, I don't know what else to do :P).

If everything is working fine in OE I will probably sit tight and leave well enough alone and enjoy the homebrew. It's probably stupid but what got me all concerned about key corruption was reading that the official firmwares after 3.30 check for corrupted keys because I figured there may be a game/feature/development which makes me want to go back.

I was under the impression that there were "corruption free" downgraders now and that I probably mistakenly used an older version. I used the "Dark Alex Easy Downgrader by csfreakno1". Is there any way I could find out if that particular downgrader corrupts? :\

[Brad]

That downgrade does not try to corrupt it just happens on some PSP's cause its the first version released.

I also think you don't understand what 3.40 OE-A is, its 3.40 firmware but can run Homebrew among allot of other nice things.

Pros and Cons of OE

Once on OE and you run the fixer it will fix the issue "if there even is one" and you can always go back and install official firmware if you want. (Sony 3.30 +)

My brightness button seems to be working as it did before. There are 4 steps while plugged in, each press makes it brigher. That's normal, right?

Like I said, I was more concerned with what effect key corruption would have on going legit - which I now know is a problem - so I want to make sure my keys are uncorrupt. I only wanted to go OE if I knew I could go back because it's not that big of a deal to me, but I did not read enough before I started. Obviously I would not have used that partuicular downgrader if I understood all of this stuff ahead of time.

Regardless, at this point I just want to check to see the status of my keys and fix any corruption problems so that I can go legit if/when I want to. Even if it is stupid!

Like I said, update to 3.40 OE-A and run the fixer. Its may find something it may not. And if you ever find yourself wanting to go to a new official Sony update, downgrade back to 1.5 from OE and update to the desired Sony update.

Thanks. That's exactly what I wanted to hear. I am happy to learn it only happens on some PSPs. I had the impression that "idstoragechange" worked by corrupting the keys. My downgrade went off without a hitch so hopefully there is no issue, as you said (and if there is hopefully it is easily fixed).

You're right on the money, I do not really understand this stuff. I'm sorry. That's why I appreciate the help and patience, I know it can be annoying talking to clueless noobs!

I thought I had a good handle on it before I started, but then after I successfully downgraded I started reading all that stuff about key corruption and the problems some people have had and how Sony started locking out corrupted key users and I got all bogged down and thought I did the wrong thing for myself. I probably worry too much. Anyway, your reply is reassuring and your advice is appreciated. I think that's what I am going to do.

I have not read this thread in awhile so sorry if I am bringing up old newsm, but has there been any progress on the downgrader for people with 3.11 firmware?

If so could you link me. Thanks in advance.

[|-Anubis-|]

No progress for people higher than 3.03

Sorry.

Thank you very much Ill just keep waiting.

Hi i am new here and This is what i am going to use to downgrade to 1.5

Xtrusion Easy PSP Downgrader
it downgrade to 2.6-1.5
It's a easy downgrade install for noobs like me
website can be found here
http://psp.xtrusion.es/content/descargas.htm

so my question is.
Is this a good thing to downgrade from 2.6-1.5 without bricking it?

[Brad]

That seems like a ok way to go. Just makes sure not to run it if you have a TA-82.

I like going the manual way by updating to 2.71 then following the guide on page one but its up to you.

[hellsingxx]

So it's more safe to follow the manual guide?

Just want to know.
My psp wont brick right?
Because i bought it yesterday

[Brad]

If you follow the directions you will be fine.

The 2.71 Guide in this thread does not need GTA LCS. But if you have it on hand you can use the downgrade you posted above.

[hellsingxx]

Just one more question

If i got TA-082 and downgrade it to 1.5

Can i upgrade it to 3.40 OE-A without bricking it??

[Brad]

If you got a TA-82 upgrade to 2.71 and follow the TA-82 2.71 downgrade guide on page one.

As for the ISO question, we cant' help you cause of are current Piracy Policy. But ill just say your on the right track.

[hellsingxx]

Sorry just 1 more question

Will this work with a 2gb Sandisk memory stick pro duo?
Just a stupid question.

Yup it will work fine on that memory stick.

[Hindman]

Total newb question: I have the 3.03 upgrade, but have no idea how to install it. Do I just copy that file to /psp/game/update or what?
-= Double Post =-

10. Once finished the PSP will ask you to press X, after pressing it will reset it self.

11. If a blue screen (BSOD) comes up saying that the settings are corrupt press X to continue.

12. Enjoy the new 1.5 PSP

I'm pressing X like step 11 says, and nothing is happening.
Is my PSP bricked?

[xdantex]

[Brad]

PSP with firmware 3.10 - 3.40 can't run Homebrew or be downgraded.

There is no exploit to allow this.
