| − | Few questions...the S5L8900 WTF is an 8900 file. Is it encrypted with the old 0x837 key derived from the old GID key or the new keys? Also, my theory is if the DFU exploit still exists in the new touch, we can send an exploited WTF and from there send a patched iBoot, we could possiby get iBooter or openIboot working, we could decrypt the KBAG's. Are there any problems with this theory? |

| − | 4. If you can get an iBooter or implementation of it for 2.*, let me know. The iBEC is not encrypted and that would surely suffice for the purpose that you speak of. But I have some reason to believe that for some reason the iPod Touch 2 can be downgraded to an iPod Touch firmware. The reasoning behind this is that it has a totally new application processor, yet for reasons unknown, there is still support for 8900 files in it. As many know from clues hidden in firmwares dating back to 1.2 (The first build of 2.0, made available in March), 8900 encryption was used. I would have thought by now Apple would have re-written it to not have legacy 8900 support. But who knows...I may try to snag one and play around with it if that freeiphonetrade site or whatever it is called actually is legit. |

Then we could decrypt the ramdisk, rootfs, and get on our way with a jailbreak. Also, with your point about downgrading, if you are correct then we should be able to (possibly) downgrade the touch2 to 1.1.4 and use ibooter/openiboot with no problem? I have a feeling the only problem with that would be iTunes 8 will forbid even a DFU downgrade to 1.1.4, so we would either have to downgrade to iTunes 7.5 with the touch2 drivers still intact and then restore from there. That being said, I bet the only way a downgrade to 1.1.4 would work would be with a patched WTF and the DFU exploit not fixed by apple in the touch2. Should be an interesting few months for the devteam, assuming they even try to work on the touch2. Maybe we should talk to planetbeing regarding iBooter/openiboot in 2.1... |

Anyone got one? ~geohot
Cool, didn't realize I could download the new Touch fw.
You have a decrypted copy of iBSS in \iPod2,1_2.1.1_5F138_Restore\Firmware\dfu\iBSS.n72ap.RELEASE.dfu
I'm almost sure the DFU exploit is still there, because the DFU file is still 89001. Use my iBoot patch to patch that iBSS and run the AES engine straight from iBoot. Use iran to upload the patched version.
okay now
Is the DFU exploit there? Test it using "iran", not iTunes. If not, then we are up against something. Otherwise, why the long talk page?
assuming the DFU exploit is still there...
1. Do the old iBSSes and iBECs run(with exploit)? If so, you are done, just use my iBoot patches to run the AES engine right from iBoot. No chainloading required.
2. The DFUs all weren't encrypted on the iPhone firmware, including the iBSS and iBEC ones. Still true? Then theres iBoot.
assuming the DFU exploit is gone...
1. If the old iBoots run(without exploit, from normal DFU), run 1.1.4 and use the diags exploit to strap into a patched iBoot.
questions
that actually would make a lot of sense. the only thing is, would new code be needed to decrypt the kbags, or business as usual since it is just a gid key change? i would think it is the later but im no crypto genius so i cant be too sure.
I know the jist of how the diags exploit works, but how exactly would i strap on another iBoot. basically, do you have code handy for that? preferably in the form of already laid out 'mw's so that i can just copy and paste :P but thats asking too much. in all seriousness, please let me know if you do as i paln on picking one up soon.
wait!
Although it for some strange reason parses 8900 files, I just realized...they could have just fixed the bootrom stack overflow, and kept parsing intact for whatever reason...
i have one
i have the 2g touch if anyone wants me to do any testing. I use a mac, if you need to contact me email me at fiftyfour123@gmail.com cuz i won't be checking this page.
I got one too. I'll have to stop using it before November since I'll give it as a birthday present, but not I can test that it is working well :p. My email address is julienf.collin@gmail.com Geohot, if you want to contact me, mail me, use google talk (either via gmail or via iChat for mac) or this address as a Windows Live Messenger.

i have a 2g touch. I tried to upload an old iBSS but I get 'Memory image not valid' when I try to run it. Any ideas?
