M33: Why patch key 5 in the Kxploit patch for 1.5?

[Erland]

This is addressed to M33. Why do you patch key 5 in the kxploiter for 1.5?

To me it seems if you are running 1.5 then you don't need the key to be patched. It should already be patched.

The reason I say that is because from what I understand you cannot run 1.5 on a TA-082/086 motherboard that does not have key 5 patched.

So if you are on 1.5 why patch the key?

Also if you are patching the key why not patch it the same way n00bz and ChillyWilly patch it to make it more universal?

If you don't have it I'm more than willing to ask them to send you the code to do it or at least let you know how they do it. You know which spot gets changed to what...

I'm just kinda worried my TA-079 is gonna be patched if I ever run it on mine I don't have a key 5 that needs to be patched and really don't want to have it modified if it's not needed.

Thank you for reading this.

M33 your great...thanx for all the hard work.

key 5 only needs to be "corrupted" by 1 byte in order to run the 1.50 ipl. the key needs to be patched when updating from 1.50 to 3.10+ (i think 3.10) becuase it wont be able to run the firmware

Today I restored 5th key and install 3.52 Sony fw. (when 5th key being not patched - the installer returned an alert message).

But when I returned to 3.52M33-4 cfw by restoring nand dump with pandora unbricker without restoring ID Storage keys - I got brick.

When I restore nand dump with restoring ID Storage keys - my 3.52M33-4 been success restored.

And we got for TA82 mother board:
unpatched 5th key - use only 2.71-3.52 official fw.
patched 5th key - use 1.50, 2.71-3.11 official fw + custom.

If you have a TA079 i think that it isn't necessary run kxploiter for 1.5.

[Erland]

The kxploiter is to allow running of the 3.32.M33-4 Updater. It was written in kexploit which is not supported by 1.5 only 1.0 ofw. Thus the kxploit has to be run no matter what your motherboard version is.

and you have to have a corrupt key to run 1.5 and cfw only. If you are on 1.5 then there is no need to patch the key again.

If you want to run 3.30+ ofw you need an unpatched key 5

===========================================

So basically if you are on 1.5 then there is no reason to patch...yet the kxploiter does it's own patching of key 5....why?

Let me correct my self.

The 1.5 Kxploit patcher is a patch for 1.5 that is written with the kxploit exploit to all the running of unsigned eboots. Basically it runs 1.0 unsigned eboots.

So if you are on 1.5 this patch has to be applied to run the M33 Update.

But this still doesn't explain why the patch key 5 which should already be patched if your running 1.5 OFW...

If I'm correct, then:

If you're used pandora unbricker, you got 1.50 without ID Storage.
Your keystate can bring to you 3.30 official FW.
But if you install clearly (without fixing 5th key) 3.30+ CFW you got brick, because CFW needs 1.50 5th key, not 3.30+ supported 5th key.

So xploit patch sets 5th correct key to use 3.30+ CFW.

Yesterday, I got brick on 3.52M33 while restoring nand dump without restoring ID Storage Keys, and my 5th key was for 3.30+ official fw.

Xploit patch makes correct thing, patching 5th key.

If you so need original 5th key - fix it yourself.

You are right....About all of that..but your missing one point...

You can't be on 1.50 OFW with a key 5 for 3.30+ It will brick....So there is no need for patching key 5...It's already patched, duh....your on 1.5!

You can only turn your Key 5 back to an unpatched 3.30+ on an official 2.71, 2.80, 2.81, 3.00, 3.01, 3.02, 3.03, and 3.10. The reason is because CFW requires parts of 1.5 so it can't be patched, which means it's already been patched because either your on 1.5 or your on CFW

If you end up on 3.30+ with a patched key then you changed changed it back to the original at some point, which means to go back to 1.5 or CFW you have to patch it again.

do you mean that if i used my pandora to return a ta79 3.52 m33-4 to 1.5 (to try out the battery/ms combo) then installed m33 again (using kxploit obviously, to get the eboot to run) it patched my key5 when i am on ta79???

[anton85]

After some experiments, I found, that, Pandora after startup "downgrade using 1.50 eboot.pbp", IF there are TA82+ PSP and 5th key is ORIGINAL (not patched), Pandora says:

You have a TA082+ PSP, which needs to be patched before it can be downgraded. Pres X to start the patch. By doing it, you accept the risk and ALL the responsibility of what happens. If you don't agree press R-trigger button.

(but if your key is already different, than "original" - you don't got this message)
(my psp with "unrecognized key state" of 5th key, that I damaged by wrote into it a random-text - is successuly booted CFW)

If you cancel ID Storage 5th key patch, you return to main menu of pandora recovery.

I have noticed it will not patch a TA-079 or TA-081....

But there have been reports from Chilly Willy and several other people that it does change key 5...

I just have not found out under what conditions.

[ardbuzz]

just checked my key5 (ta079 original 1.52FW Euro PSP 1003) and it had not changed from before using Pandora

[TheJoker]

@anton85...
everything you said is true... not me or the original author will argue with you sir... it is true everything...

but you misunderstood the original topic...

let me try to explain it more... i have TA-082... unpatched... original key 5... i'm on 3.52 official firmware...

use the pandora... to downgrade my PSP to 1.50... PANDORA will patch the KEY 5 because 1.50 can't run on TA-082/86 without patching the KEY 5...

now i'm on 1.50... key 5 is patch by PANDORA... using chilly willy method...

you need to run kexploit of M33 to run the M33 updates... but M33 kexploit will patch again the Key 5...

you are already on 1.50... meaning the KEY 5 is already patch... so why the kexploit patch the key 5 again...???

i know M33 kexploit is playing safe to patch the Key 5... but you can't run kexploit if the key 5 is unpatch in the first place... because kexploit need 1.50 firmware... and 1.50 firmware need key 5 patch...

then why m33 kexploit patch the key 5 again...???

you did get it this time...???

thanks a lot...

[Erland]

@TheJoker...

That is my point exactly....

I guess it's done in a preventative nature just to make sure it's been patched....I was just hoping for some feed back from M33 themselves to see what they had to say about this...

And maybe see if they can make the next one the same way Chilly Willy did his to have a more universal patch.

I'm not complaining just....curious..

[Fejwin]

My guess:
The patching method m33 uses is superior to pandora or chilli willi (whatever). ^^
They just do it to do you a favour! XD
