No more cache troubles
OK, figured it out, the A5 cache is not a problem anymore.
I sorted it out by doing the untether in a single thread and by flushing all the dcache then all the icache in a row at a strategical point of the process.
It took me like a hundred of tests to find the key. Hard for the nerves.
For the tech guys, here is a link explaining issues related to self modifying code ( or code patching ) on the ARM platform : Caches and Self-Modifying Code - ARM Community
Another news : I discussed with @saurik today about the launchd boot process, and he's found one missing piece of the puzzle I needed to have a perfectly stable jailbreak. He's definitly one of the best iOS gurus out there. Thank you saurik!

Hello.
Here are the news of the 4S week-end.
The untether fails right now because I'm having processor cache issues.
I'm close, but I can't figure out what happens. It certainly has something to do with the Cortex-A9 cache management.
I could sort it out quick, it's a matter of chance.
I'll report you my progress tomorrow.
BTW: I removed (sorry) the greetings messages so that only articles related to the jailbreak remain in the main page. AFAIK Blogger don't have the option to move or fusion messages while keeping the comments.
Ciao!
