Hey, I'm having a problem while trying to downgrade my PSP Slim running OFW 3.73. I used that TotalNewbie Easy Installer thing, and I'm pretty sure I did everything the right way, but when I put in the Datel TOOL battery I just got, I see a blank screen.

Now, I know that this is normal on a Slim, but the readme in the installer said that once you have all the files extracted to the PSP, you just ignore the blank screen, and just press X to install the CFW. I press X, but nothing happens, and I don't hear the little sounds that you usually hear when the PSP is processing something. Then, when I boot the PSP with the normal battery, I can see all those apps that were installed, but if I try to run any of them, it just goes back to the menu screen and gives me the message "This game cannot be launched" or something like that. I'm thinking I'm missing some important files that I need or something... but I'm not sure. I get really overwhelmed by stuff like this.

I'm totally lost... I hope someone can help me, I'm new here, and I don't know how frequented this board is.

Also, if I'm posting this in the wrong place or something, sorry in advance.




By the way, here's some excerpts from the readme for the installer that seem most relevant to my problem, in case that helps.

_______________________________________________________________________________

Slim Pandora for FW 3.60: (Option 3)
------------------------------------

Insert the pandora battery and the memory stick in the psp slim. It will boot. You won't see
anything on the screen, because that kernel doesn't support the slim screen, but it is OK, you
don't need a screen for the installation of 3.60 M33.

From here, you have 3 options:

- Press X to install M33. The process will last just few seconds, since the installer only
needs to install the M33 custom prx's and IPL. After the process is finished, the installer
will shutdown the psp automatically.

- Press L+R+triangle to uninstall M33 and go back to original 3.60. Note: this can't unbrick a
psp slim, it will just remove M33 ipl. There is currently no unbricker for the psp slim, but
we plan on doing one in the future.
After uninstallation, psp will be shutdown automatically.

- Press square to dump the PSP Slim nand. Watch out: you need 66 MB of free space in the
memory stick for this, otherwise your memory stick may end corrupted.

This option uses the team C+D nand dumper. When the memory stick orange led stops blinking,
the process will have finished, and you can either shutdown the psp, or use one of the two
previous options.

Universal Unbrick: (Option 4)
-----------------------------

- Press X to install 3.71M33-2.

[COLOR="Red"]Like I said, I tried this and nothing happened. Honestly, I don't know if I'm using an outdated installer or anything... [/COLOR]

- Press O to install original 3.71 (rest of the process as the X option)

[COLOR="Red"]I tried pressing pretty much every button, but nothing happened...[/COLOR]

PS: and I have a question in case anyone replies. If I'm missing anything, I think I'm missing some stuff you get from the Phat PSP, because I never had one and don't know anyone I can borrow one from. I see so many different guides saying different things, some say you HAVE to have the phat PSP, some say you don't need it if you do this or that. My head's practically spinning from all of that crap. So I just want an answer... do I, or do I not need a phat PSP?

Try these bud.

Thanks! I'll give it a try...

have you tried using Despertar Cementerio instead?

Okay, never mind what I said in this post originally. I have DC now, but it says I have to download "1.50, 3.40 and 3.90 update eboots"... I don't think I've downloaded those yet... where do I get them?

Yes, hold on. This is Desperter Cementerio, BTW.

Okay, I downloaded DC from Dark Alex's website, so it looks like all I need now is the eboot files...

EDIT: Well, I THOUGHT I downloaded it, but in the folder there's no application or anything... I'm super-confused now....

Okay, I've ran DC, but it doesn't work for some reason, I get this error:


Target DRIVE is 5
Check partation Sector
Cannot open device \\.physicaldrive5

But then it says:

Installation was successful.
On boot hold the Digital-Up key to boot DCv4.
Holding nothing will boot the PSP as normal.

"On boot"? That implies the PSP should have turned off, which it didn't...

I MUST be doing something wrong... This is really frustrating....

That implies "Turn off your PSP, and hold up while it boots to do DC"

Well, I didn't think of that... but now I HAVE tried that, and it still isn't working. I still get the black screen with the TOOL battery, and when I press buttons nothing happens. Holding up doesn't do anything. Sorry about seeming like such an idiot, but this is all really confusing to me...

I know I asked this already, but do I need a CFW fat PSP for this? I never really got an answer to that question. I'm just trying to make sure, because no matter what I try, I can't seem to get this to work...

Also, like I said, I'm using a PSP Slim. Just to make sure that's clear with everyone.

No, you don't.

Okay, so just to clarify, all I need to do is download the files you linked me to, and I have everything I need, along with my 1 gig memory stick and Datel TOOL battery? Sorry for asking so many questions, I'm just trying to make sure I'm not wasting my time.

I already downloaded that... in fact, that's what's been giving me problems, I run the installer thing, and I can see it under "games" on "memory stick" on my PSP, but if I try to run it, it just says it can't start the "game". Also, booting it up while holding down up, with or without the Pandora's battery, doesn't do anything.... I know it's probably a mistake I did while trying to install it... I'm just not sure what exactly to do. The walkthroughs I've seen all look pretty murky at parts that I'm not completely sure about. Sorry again for my noobness. [/quote]
