Nov 07, 2019 Kanzi Cable Iphone. 11/7/2019 Genuine iPhone & iPad Cable These Apple cables are exactly the same as you would have received with your Apple device or purchased from the Apple store – just at a fraction of the cost. The Apple Store retails this cable for £19.00. It can be retrieved over IDBUS using Serial Number Reader cable (or Kanzi, they are basically the same thing, except for a different USB PID and a little bit different enclosure) In simple words, by sending this blob to ttrs.apple.com, you can get device's serial number. This mechanism is used by Apple Store/Apple Premium Reseller' staff to.

The DCSD Alex cable is used in factories to communicate over serial to run tests and write to the SysCfg (for serial definitions, etc) during production. These cables are produced by ShenZhen Alex Connector Co., Ltd. in China. They can be purchased from obscure markets. There are two known types of DCSD cable. An older one, with lights and only one USB female USB connector, and a newer model, which lacks lights, and has two female USB connectors.

This cable is made specifically for USB-C devices such as the newer models in the iPad Pro line, this cable also supports USB 3.1.USB connection from the main board splits out into a Y-style cable but turns back into one connection in the USB-A male connector .

There's not much on the back of the board that you couldn't technically see from the front, no ICs or anything of interest really.

Other notes
Kanzi Connect
- The Lightning Connector has a specific Accessory ID flashed to it for enabling serial via the Tristar chip.
- This PCB is quite easy to replicate, but without the proper Accessory ID you will need to mimic the protocol similar to how key2fr did in his research.
- In theory, you can use the Tristar for JTAG through a similar board, but JTAG gets disabled by the device during boot due to production fusing status.
- In USB-C capable Macs Apple takes care to note the low speed USB2 pins on the TOP or BOTTOM of the connector (which are usually identical to support passive USB-C <-> USB-A cables). This suggests that these pairs may be treated differently just like how the lightning DCSD cable had a proper TOP and BOTTOM side, which would provide a second USB device on the same plug.
Uses
Verbose Boot
One use of the cable was to view verbose boot. You could access this by setting debug uarts in iRecovery or nvram, however, since iOS 9, this output has been obfuscated. Youtube to mp4 converter free for mac.
Shell over serial
Using qwertyoruiopz'sserialsh, it is possible to get shell over serial. Keil c51 9 51 keygen. This is useful, because it does not require any additional daemons other than those shipped with iOS. An example use case for this would be protecting against bootloops.
Debugging the kernel
Using the DCSD cable, it is possible to attach GDB to the iOS kernel, and pause it's running.

If you’ve got the skills, then spending a few grand on a special type of iPhone or iPad and a special USB-cable may be enough to truly hack the iPhone and expose all of its secrets. That’s not to say that it’s easy or legal to do so, but a huge investigation reveals details about the underworld of iPhone hacking, which appears to be a flourishing and lucrative business. One piece all episode subtitle indonesia mp4.
Priced at around $2,000 on the gray market, the proprietary Apple USB cable you need is called Kanzi, and it’s the only one that you can use to access special data buried in an iPhone, once you connect it to a computer. According to Motherboard’s Versaworks mac download. Error finding your systems active partition. months-long investigation, you also need to buy developer-fused iPhones that can cost you four or five figures — the iPhone 6 is $1,300, the iPhone 8 Plus costs $5,000, and the iPhone XR is a whopping $20,000.

These dev-fused devices are special types of iPhones that are used for testing and debugging purposes. Thus, the iPhones do not have all the standard software defenses enabled, and security researchers would be able to learn some of the secrets hidden behind the security in iOS.
Dev-fused iPhones that were never intended to escape Apple’s production pipeline have made their way to the gray market, where smugglers and middlemen sell them for thousands of dollars to hackers and security researchers. Using the information gleaned from probing a dev-fused device, researchers can sometimes parlay what they’ve learned into developing a hack for the normal iPhones hundreds of millions of people own.
Comparatively, the iPhone that you buy in stores is “prod-fused,” which means it can’t offer hackers access to the special dev mode. Here’s how one former Apple employee described it:
Prod fused means there’s a specific pin on the board that is ‘blown’ in the production phase. Ies ve pro crack. The board checks that pin to see if the device is prod or not. If it isn’t, and the firmware is dev version, then certain features are enabled.
Diablo 2 decrepify vs amplify damage. While Apple has been trying its best not to lose access to any of the dev-fused phones it has made over the years, it looks like there’s a thriving black market for them and you can easily find a model to suit your needs.
