FW2.80 DownDate to FW2.71 for TA-079~086 PSP v0.01 By 0okm RELEASED

[belialone]

i just cant imagine how it would be if had a ta-82

i downgraded my white ta-79 from 2.71 to 1.5
two weeks after i bought it
these two weeks showed me the light
i was browsing around the net to see what news where available for psp
then i stumbled over http://www.psp-hacks.com and learned about homebrew
my eyes popped out while reading what this little device was about
now im using all kinds of homebrew

and im spreading the word of homebrew by downgrading my friends psps

belive in homebrew

I think that people see that it was released by Ookm and automatically assume it's for TA-082. I mean, even I had to double and triple check and I don't even have a TA-082.

I do think you are all wrong.... This downgrader should woek for PSP Mobo's from TA-079 to TA-086 (including also the infamous TA-082)

Did he check that he had the correct dump with all the necessary files before downgrading? Probably no, so this is another of those cases of not making sure 4 times (or better even 5) prior to do something that can be critical for your PSP...

Plus I am sure that an easy downgrader pack will come out soon, so people unsure of having everything necessary should wait for it.

Anyway, sorry for your loss... It's always sad to hear that a PSP has bricked.

It may be that the post title is misleading.

I would assume :

TA-079~086

means all PSP's in the range TA-079 through to 086, and not TA-079 & 086

If it was just for those two PSP types, the title should be :

TA-079 & 086

It has to be for TA-79 through TA-86. Everyone (including me) was begging for a downdate from 2.8 to 2.71. I will wait for some successes or easy installer also. As I've never done it before so i'm sure I'd screw it up & brick it. I'm assuming when it says place this file in ms0 means just in the root of your memory stick? This is awesome news!!!! I'm so excited I've been waiting 6 months stuck at 2.8 waiting for this. Now I can go buy games that require above 2.8 also once I get devhook or 3.02eb installed & play my PS1 games.

Here's the part that I don't understand or am misreading:

use PBP Unpacker to unpacker FW2.71 EBOOT.BPB
　copy FW2.71 DATA.PSAR to ms0:\
　run PSARDumper on FW1.50PSP
　then "Press circle to dump encrypted without sigcheck and decrypted reboot.bin."
　to Dump "FW2.71 File"

It says use PBP unpacker then run PSARdumper on FW1.50PSP. Well I don't have a 1.5PSP I have a 2.8 so does that mean we have to wait for someone with a FW1.5 to run the unpacker & then run the PSARdumper on their 1.5? I'm guessing this is where the brick came from....someone ran or didn't run the psardumper on a 2.8 with eloader or something.

[belialone]

correct kieso you need someone with a 1.5 psp to dump the psar file
you could try searching the web for a dump but incase the dump is wrong or just incomplete it bricks your psp
so i would only use a dump made right in front of my eyes (using a 1.5 psp)

[kieso]

thanks for clearing me up on that. I'll just wait for an easy installer. I've waited 6 months, what's another couple days gonna hurt. If I knew someone with a 1.5 then i'd do that but I don't.

About time Ookm actually released a downgrader to the public for all of those with TA-082 PSPs.

[fistikuffs]

Guys as far as i'm aware this IS for the t-082 mobo

[Anger]

i just relayed the message - no need to shoot the messenger.

i am led to believe it is for all psp revisions because it says its for ta-086 motherboards which are as impossible to downgrade as ta-082 mobos are. now he also says on his site that it was leaked and that you basically are trying it at your own risk. this does not mean it will 100% work but it should do.

the only reason he released it is because it was leaked - this doesnt mean its more stable than the last release, it just means it was supposed to be tested before being released. i have a friend waiting to downgrade his 2.80 but i still advise him against it because this is still buggy.

so i advise you to do the same - wait until people with money or warranties have tried it and wait till its 99.9% compatible.

*EDIT*
i just read it again - it is NOT for ta-082's.
he says use it on ta-079~086 but below that he says do not use it on any other ver. psp - he specifically didnt mention ta-082. this leads me to believe it is NOT for ta-082 psp's yet and that could be why some people are getting bricks.

spread the word please.
