Yea. It's very useful. If it's ok with -Xandu-, I might release a little more information the more testing I do.

SamuraiX, I believe (not enterely sure though) that what you're talking about is no longer a problem.
PSP-Hacks Forums, which are not as strict with legal stuff as other sites (not saying this is a good thing), host a tutorial and an installation program that includes the DATA.PXAR. Browsing this tutorial and the answers, I don't remember anyone saying they'd bricked their PSP.

It would, however, be a large file which would tax servers and take forever to download on the psp's wireless.

As ExcruciationX said, there could be a list of servers hosting this file, asking trusted people and psp websites to do it. It indeed would be a large file, but if enough people host it, I think it'd be worth the trouble.
About the wireless, I guess the update could use a USB connection as well.

A safe and easy custom firmware update, and there is no longer any service Sony is offering that the PSP homebrew scene isn't, am I right?

So DAX, I hope this reaches your ears (and that I'm not talking $#@!

)

Either way, every dxar file made has to be the same, otherwise the SHA-1 would be different for all of them, wouldnt it?

I think you're thick.

Just kidding.

IPL stands for "Intitial Program Load".

It is the start up phase of any computer (in this case, the PSP). When you flick that power switch, the IPL will run. It will then procceed to load the stuff on Flash0:\.

Valid point ... then why not have the DATA.DXAR file written to (and read from) the root of the memory stick instead? Since the update flasher does a check of the file anyway before flashing, I can't see why it would be a problem - and the extra cautious could manually check the file before running the update.

I'm basically throwing out ideas about how the process could be further automated than it is. I'm not criticising Dark_Alex, btw, I just think that there are both small and big steps on the road to having an automated update, and we need not let the fact that there's not a solution for the big steps stop us from making inroads into the small ones. Make any sense?

Good idea, I was wondering what u needed beta testers for...

**LilSwish722** · February 13th, 2007, 19:21

Keep in mind guys, we are still testing this and is a work in progress.

Thats why Dark_Alex modified psar_dumper aka Setup_Maker to rely on your PSP's unique IPL ID.

So the lesson here is you can NOT use someone elses DAX file!!!!

thats just plain wrong... you can use anyones correctly created data.dxar on any psp

However, you can't distribute the DXAR file. Hence why there's a manual process for generating it, because *generating* it is fine, it's distributing it that's legally fuzzy.

Although, the DMCA may well make the PBP unpacker/PSAR dumper that is used in the updater illegal anyway. The DMCA makes most things illegal.
