14 DAY TRIAL // Chronic Dev’s Pod2g is keeping fans updated on his progress regarding the untethered iOS 5 jailbreak informing on his blog that Apple’s A5 processor is a tough nut to crack.
“The untether fails right now because I’m having processor cache issues,” the hacker wrote in a blog post. “I’m close, but I can’t figure out what happens. It certainly has something to do with the Cortex-A9 cache management,” Pod2g wrote yesterday.
In a subsequent entry made just a few hours ago, the tinkerer came back with good news, saying “OK, figured it out, the A5 cache is not a problem anymore.”
He elaborated, saying, “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,” said Pod2g.
As if the terms used in the above paragraph were aimed at regular users, Pod2g says that “tech guys” can visit this here link for a better understanding of “issues related to self modifying code”.
As a side note, the infamous hacker says he’s had a chat with Saurik, the Cydia gatekeeper, about the launchd boot process.
The developer behind the jailbreak alternative to the iTunes App Store has reportedly found “one missing piece of the puzzle [Pod2g] needed to have a perfectly stable jailbreak.”
“He's definitly one of the best iOS gurus out there. Thank you saurik!”, Pod2g concludes.
As usual, the Chronic Dev hacker doesn’t provide an ETA for his untethered iOS 5 jailbreak, but he certainly seems to be making a lot of progress.
The best news is that he’s also making progress with devices using the A5 chip - the iPhone 4S and iPad 2.
