Newly discovered iBoot exploit makes A5(X) devices jailbreakable for life

By Cody Lee on Feb 1, 2014

“So looks like all my A5(X) devices are fully untethered and jailbroken for life now. :)” iH8sn0w, the developer behind Sn0wBreeze and other jailbreak apps, tweeted this afternoon. The comment has caused quite a bit of excitement, as we haven’t seen anything like this in jailbreaking since LimeRa1n.

iH8sn0w says he doesn’t have a bootrom exploit though, but rather a “powerful iBoot exploit.” And although it doesn’t look like he’s going to do anything with it right now in terms of a public release, it sounds like he’ll be able to use the exploit in future jailbreaks, and to find similar bugs in A6/A7 chips… Read More


Inside 2013 Apple TV: redesigned power-savvy A5 chip, cost optimizations

By Christian Zibreg on Mar 15, 2013

Apple shipped five million Apple TVs last year for a nearly $500 million in additional revenue. That’s a very successful hobby and while talk of Tim Cook & Co. building a standalone HD TV set remains just that – rumor mongering – Apple has quietly retooled the $99 set-top box, with most of the under-the-hood tweaks aimed at optimizing production costs.

AnandTech took a peek inside the gadget and found some minor changes. The publication found a significant reduction in the new model’s power consumption, directly related to the optimized A5 chip, leading AnandTech to speculate that perhaps Apple could use this chip for another device, “perhaps one powered by a battery” (hint: iWatch)… Read More


Apple actually removed one CPU core from Apple TV’s die-shrunk A5 chip

By Christian Zibreg on Mar 13, 2013

Silicon analysts over at Chipworks were able to conclude yesterday that the smaller A5 package, which was recently discovered inside a retooled Apple TV, is still being fabbed on Samsung’s 32-nanometer process rather than on TSMC’s 28-nanometer technology, as some watchers speculate. Compared to its 2012 counterpart, the new A5 with a 2013 die is noticeably smaller, prompting questions on how Apple has managed to achieve a smaller die without changing fabbing technology.

The full A5 floorplan Chipworks published this morning reveals the culprit: the new die is smaller because the package contains just one ARM CPU core. Now, Apple has always rated the Apple TV as single-core, but previous implementations called for dual-core designs with one core intentionally disabled, though still present.

In removing one CPU core altogether, Apple’s silicon team was able to shrink the die size without having to switch to a more sophisticated fabbing process technology… Read More


Apple’s smaller A5 chip is still being fabbed by Samsung

By Christian Zibreg on Mar 12, 2013

As we reported Monday, a retooled version of Apple’s $99 set-top box has been found to have a die-shrunk version of the iPad 2’s A5 chip rather than the A5X package, as previously speculated. Some market watchers even thought the new package is fabbed on Taiwan Semiconductor Manufacturing Company’s (TSMC) new 28-nanometer process. However, after conducting a thorough analysis of the silicon under sophisticated microscopes, chip wizards over at Chipworks and Silicon-IP have determined that the new A5 package is being fabbed on Samsung’s 32-nanometer process after all… Read More


Retooled Apple TV found to have die-shrunk A5, not A5X

By Cody Lee on Mar 10, 2013

Earlier this year, a software update for the Apple TV (5.2) revealed a new device labeled “AppleTV3,2.” After digging through some FCC documents, and some code, it was discovered that it was just a tweaked version of the third-gen ATV with an A5X processor.

Or at least it appeared that way. The retooled set-top box has just begun hitting Apple Stores, and the folks over at MacRumors were able to pick one up and crack one open this weekend. And they’ve determined that its processor is actually a die-shrunk A5 chip… Read More


Geekbench: the new iPod touch cannot hold a candle to the iPhone 5

By Christian Zibreg on Oct 15, 2012

Apple’s fifth-generation iPod touch has arrived to some raving reviews, representing a major upgrade over the previous model with the same four-inch display as the iPhone 5 (sans a cheaper assembly), the thinner chassis (only 6.1mm), the new Lightning interconnect, a five-megapixel iSight camera with custom optics and the A5 chip, also found inside the third-generation iPad and iPhone 4S. First Geekbench benchmarks show that the new iPod touch is nearly as fast as the iPhone 4S, but not even half as fast as the iPhone 5, Apple’s first iOS device to utilize the brand new A6 processorRead More


Apple now accounts for 8.8% of Samsung’s revenue

By Christian Zibreg on Aug 7, 2012

Despite a massive legal spat between Apple and Samsung over who copied whose tablets and smartphones, the two frenemies remain dependent on each other’s business. Samsung makes Apple’s in-house designed mobile processors and supplies the iPhone maker with massive amounts of displays and flash memory chips for iOS devices.

A new report suggests the Apple account is worth a whopping 8.8 percent of Samsung’s revenue, making Apple Samsung’s largest customer and perhaps giving Cupertino some added leverage in its business and legal dealings with the South Korea-headquartered conglomerate. The next biggest Samsung client? Read on… Read More


Apple’s head mobile chip designer leaves for AMD

By Cody Lee on Aug 1, 2012

Back in June we learned that Bob Mansfield, Apple’s Senior Vice President of Hardware, would be retiring. Bob has been a familiar face on Apple’s executive team for several years, and an integral part of the success of the iPhone and iPad.

And now it looks like Apple is losing another important piece of its iOS squad. A new report is out today claiming that Jim Keller, Apple’s lead chip designer, is leaving the company to take a new position at Advanced Micro Devices (AMD)… Read More


New iPod touch said to feature a 4-inch display, A5 chip

By Cody Lee on Jul 24, 2012

Hot on the heels of last night’s note from analyst Ming-Chi Kuo, comes a new report regarding the future of the iPod touch. If it holds true, the mp3 player could be getting quite the makeover this fall.

According to the new dispatch, the next-generation iPod touch will feature the same 4-inch display that the new iPhone is rumored to get, as well as an A5 processor and other internal upgrades… Read More

Upcoming version of RedSn0w will allow you to downgrade your iPhone 4S, iPad 2, and the new iPad

By Jeff Benjamin on May 8, 2012

Awesome news for those who accidentally updated the firmware for their A5 device (iPhone 4S, iPad 2, and the new iPad aka iPad 3), possibly resulting in the loss of the precious untethered jailbreak. MuscleNerd has announced that an upcoming update to RedSn0w will allow users to downgrade their firmware.

The only catch is that you have to have your SHSH blobs saved for the firmware that you wish to downgrade to. That means that if you purchased your iPhone 4S with iOS 5.1 pre-installed, there’s no way to downgrade to iOS 5.0.1 so that you can enjoy the benefits of pod2g’s untethered jailbreakRead More


New chipset gives revised iPad 2 longer battery life

By Cody Lee on May 4, 2012

When Apple announced that it was going to continue selling the iPad 2 for $399 alongside its new tablet, the company never mentioned any changes. After all, it’s the same iPad 2 that it’s been selling for more than a year. Right?

Not exactly. The folks over at AnandTech uncovered a minor, but perhaps significant, change in the discounted tablet’s A5 processor that gives the slate nearly two hours of added battery life. Keep reading to find out how… Read More


Chipworks reveals some interesting details on Apple TV A5

By Cody Lee on Apr 11, 2012

Last month, Apple unveiled its third-generation Apple TV alongside its new iPad. The set top box received a handful of updates, including the ability to stream full 1080p content courtesy of its all-new A5 processor.

While Apple claims that the ATV’s A5 is only a single core unit, the folks over at Chipworks have a different opinion. According to their findings, the chip actually has two cores and is 41% smaller than previous A5s… Read More
