Success SoftDown FW2.50 TA-082 to FW1.00/1.50

Had found a method SoftDown TA-082's FW2.50 PSP to FW1.00/1.50
But the method is quite complex, SoftDown a TA-082's PSP need about 45min

1. Use software Read Data From TA-082's NandFlash & DDR DRam
2. Analyzes the Data than make a "FW1.00/1.50 NandFlash img" that can Boot on TA-082
3. Use software Write that "FW1.00/1.50 NandFlash img" to TA-082

maybe late i will make a software to let "FW2.50 TA-082" user to dump "NandFlash & DDR DRam" data to me
than i can make the "FW1.00/1.50 NandFlash img" to help them SoftDown their TA-082 :P

1. each TA-082 PSP need different "NandFlash img"
 CAN'T use this "NandFlash img" to OTHER PSP
 That will Bricked the PSP !!
 so SoftDown each TA-082 PSP DATA need each 45min !!

2. if your FW2.60 TA-082 PSP is Update from FW2.50
 this method can work for your PSP

3. this method not work for Factory FW2.60 TA-082 PSP
 maybe later it can :P

what about fw2.6 t-82 ?

My psp is a ta-082 with the original 2.5 FW. If you decide to make the software to dump the "NandFlash & DDR DRam", i would be happy to help.
Thanks for all your great work with the ta-082's and the psp in general. ;)

good job 0okm, i hope you can make an app for this, it doesn't matter that it takes some time to softdown a TA-082 :)

>> t-082 PSPER
that method not work on FW2.60 TA-082
maybe late it can for FW2.60 TA-082 :P

>> a psp user
if your TA-082 PSP is FW2.60(update from fw2.50)
it can work for your PSP

>> bigdaddie
it takes time(45min) for me to Analyzes the data
so it does matter :P

My PSP is a TA-081.
I have unpatched GTA-LCS.
But My PSP is a 2.8 FW.
Please give the hand of saving to me.

Great news!

Question, the 45 mins of analyzing. I would expect this to be done only once and then just copy it for every ta-82/2.5 user? Or does every mb have a different nandflash id and crc or something? Just curious to why you need to redo the analyzing for every ta-82 downgrade.
Also you state that 2.6 will probably not work yet. Is this because of a probable different nandflash image on these boards?

Excuse me Ookm, but I have a 2.6 PSP that i bought used from Gamestop. It's near-impossible to find out if it was originally a 2.5 that was upgraded to 2.6. Theorhetically speaking, if I send you the data from my NandFlash & DDR DRam, would you be able to tell if it was originally a 2.5 or a 2.6?

Ookm, you totally rock.

Your efford can be felt by everyone (the downgraded / not downgraded alike). Keep up the good work, and continue the magic.

I am one of the lucky (early) one that do not have the TA-082 board and downgraded from 2.6 firmware already, just want to let you know how much I appricate your work.

I guess that the solution for 2.60'ers whit TA-082 will be to upgrade to 2.70-2.80, and then use the new TIFF exploit to downgrade to 2.50 for then to use this.

At 8/22/2006 08:08:00 am, Blogger k0pp0 said...

Well.. I've got a jap 2.50 TA-082 that has been upgraded to 2.60 firmware. 0okm, if you want me to provide anything then I will! I'd love to have a downgraded PSP.. oh yes.

Too the guy saying downgrader for 2.71 or 2.8 using tiff. That is a fake! There is no 2.71 or 2.8 downgrader. If you refer to the french video where a devhooked 1.5 is running 2.71 emulated. Is then reset and updated to 2.0 you should learn french, he even says at the and that it's fake in french :)

Oh man! What a good news for us TA-082 users!
Just want to confirm:
I have a factory/TA-082 PSP 2.5 bought from JAPAN and Upgraded to 2.6, is it now really possible to download?

Original TA-082 PSP 2.5 ugraded to 2.6 [possible]

PSP original TA-082 2.6 [not yet possible]

Am I right?

45 mins for analyzing system...then softdown TA-082 to FW1.5.It sounds you've MODIFIED original FW1.5 to adapt to TA-082 motherboard.Am I right?
So in my opinion,if we can use the kenel mode on FW1.5 TA-082 without any additional hardware support,it is possible for us to use kenel mode on TA-082 of any ver..All we should do is just hack the files of kenel mode protection and upgrade it.Can you find the part of protection in FW 2.5/2.6?
P.S. I appreciate your work very much.

hey guys, I have a TA-82 2.60
( updated from original 2.50) , who can help me to downgrade ? it's already months I've been waiting.

At 9/02/2006 11:42:00 pm, Blogger daaka said...

Since there is a new exploit, with kernel mode on 2.71, if one has a 2.71 and it was originaly a 2.5 will the downgrader work.

I'm curious, i bought an asian version psp, its white, the owner of the store is not sure if whats its factory firmware. What confuses me is the board is a TA-082 and it is already firmware 1.5, is that even possible? The psps are shipped from china i think then here to the philippines.. Are there any underground TA-082 downgrader or something? Maybe they used your idea Ookm, good job anyway.. tnx..

At 9/05/2006 03:58:00 am, Blogger acetpg said...

Verbal Mobstah....he got something interesting gotta chek it out Ookm....im kinda curious about what he has maybe he's framing us

At 9/06/2006 02:42:00 pm, Blogger ripmotor said...

Verbal Mobstah, could you upload a video in youtube of your psp showing your ta-082 with 1.5? that'd be really something if it's real. otherwise, everyone will just think you're lying....

mine is original 2.50 TA 082 upgraded to 2.70. cant'i do this?

Is there any possible ways to unbrick my TA-082 psp? My bro was one 'smarty-pants' and tried to downgrade my psp into < 2.5 firmware, and now i have a brick. Man...i've been saving so much $ for my own psp and now its ruined...:(. Anyone have any ideas at all? When i 1st bought it, it has 2.5 firmware version.

HELP. I FEEL LIKE THE $ HAS GONE DOWN THE DRAIN JUST LIKE THAT...not to mention I'm just only a poor student, barely have enough money to even support myself :( :(

At 9/13/2006 11:33:00 pm, Blogger mygodess said...

How long should we wait to get the method to downgrade the TA-082 m/b to 1.5 ? We can just do nothing but waiting until you post something :). Could you just post about the progress or reply about the question?
I know it takes long time to make the source code because I'm a software engineer also. (I made a software named "Text viewer PSP (Korean version)" and posted it.) But even it takes long time, we could just know the progress I think. (like just 1%-2% though :|)
If you need some kinds of help then I could help some of the part also. I hope you could finish your great work soon :). seeya.
