iDongle: Hardware Jailbreak

Renaud, a young French electronics engineer, has acquired a locked iPhone 3Gs for $ 600. As it turned out, the iPhone had a new bootrom, which meant that for it, as well as for the 3rd generation iPod Touch, only a tethered jailbreak was possible. In fact, you use the phone, but after rebooting it turns into a pumpkin brick.

Having all the necessary knowledge, the guy decided to build a hardware jailbreak, i.e. roughly speaking, a small microcontroller that will act as a USB host, and when connected to an iPhone / iPod, will initiate a jailbreak procedure using the usb_control_msg (0x21, 2) exploit for iBoot.

The idea is not new and has occurred to many, but the talented geek has even implemented it!


For a start, Renaud reversed blackra1n and achieved jailbreak performance on a standard developer platform with Embedded Linux on board.

Then, armed with his favorite CAD program, the guy designed a specialized board with the working title iDongle.




The case remains for small - to develop a prototype, which was done. At the moment, the prototype has a size of 30x60 mm and uses a huge 9 V battery for power.



Proof of concept:


At the moment, Renaud is collecting donations in order to order the first “large” batch of 50 devices: www.myboyfriendisageek.com/2010/hack/on-tube
