Have anyone uploaded the debug dev_flash?
yeah... go for it skfu.. and give sony a deep kick inna a..
Check it out gives some more info how to enable options:
Added to the first post as well- Thanks DJXFMA!
I've been thinking about SKFU's CFW Research and came up with this: http://thexcellerator.blogspot.com/
Well, here it is, some PS3 Downgrade Speculation.
OK, well I got think after SKFU's post when he said "We need to find a way to edit the flash directly..."
so I came up with this.
When the PS3 updates, it follows 2 main steps:
1) It copies data from PS3UPDAT.PUP to the HDD.
2) It then sets a boot flag to an "Update Phase/Mode" and then restarts and updates the flash.
If we copy our own update data to HDD, in the correct spot (I assume, it would be the contents of the PUP file, but this will need further research...), and if we can then get the PS3 to change it's boot flag, we could get it to install any Firmware we like. The spoofing side of things comes from editing the SDKHeader.bin in the PUP contents.
So, how do edit the bootflags, is the main question?
It wouldn't be a kind of PS3 GParted LiveCD...
We know that users 'could' edit bootflags (or certain ones) through the DefaultOS option in Firmwares 3.15 and below. They must be stored in the Registry (xRegistry.sys in /dev_flash2/). I'll need someone with Firmware 3.15 or below to tell me the Registry 'Key', so it can be added to a PS3 registry over 3.15...
If we can get the bootflag setting for this update phase/mode, we could make our PS3 write whatever firmware we wanted to the flash, including 3.41 on top of 3.41 with the firmware ID of 3.50, so the PS3 can go online. Does this mean that we could, in theory make the PS3 boot a OS from External HDD? Possibly boot our own flash from it (already done with JaiCraB's Firmware Loader, but still could have interesting possibilities!)
But how do we know the PS3 uses bootflags?
When I was messing with JaiCraB's Firmware Loader, when it messed up, it gave the HDD error message (anyone who's used it will know what I'm talking about!). Anyway, first time this happened to me, I switched off my PS3 and turned it on. The message still came up! Once I followed it through and restarted how it told me to, the PS3 booted up GameOS normally. At the time I thought nothing of it, but when I started thinking about this method, this makes bootflags of some sort seem like an obvious conclusion...
So, to recap!
I need someone with firmware 3.15 or below with jailbreak abilities, to tell me the 'Key' in xRegistry.sys for the DefaultOS menu, so it can be changed on firmware ABOVE 3.15...
All the best,
wow great, i hope they will make a custom that has all 3D update of 3.5.. will be great.
Is there any personal info in the registry, and how would I extract it. I wouldn't mind helping a little.
Yes, there are some personal infos in the sys file. But you can change them or delete them with xregistry.sys Editor v0.7 which you can get here in Forum.
If someone would upload the debug_flash, it would be nice
Ok i will embend the files into ps3 acid and upload the new version (hopefully) the next hours.
A lot of things have changed or are new like a progress bar for specific things.. also i have embended more sdk tools and rest i iwll tell when i put it on the web.
