few weeks ago, the iPhone Dev Team has released the latest beta version of Redsn0w 0.9.7, namely the sixth, going to correct a number of flaws and bugs found in previous releases. Among these were corrected, two major problems encountered by users with Bluetooth and Skype. However, according to segnalatoci when some users, not everyone is able to correctly use the Skype application on their iPhone after using Redsn0w. In this article we will then explain how to successfully jailbreak your Untethered device on the Mac platform
Although concerned in each case of a program still in beta, the latest release of Redsn0w is rather stable and also easy to use, so it can also be used by inexperienced users as long as they meet certain requirements, including:
- file. ipsw firmware 4.2.1 iPhone 4 ( download ).
- file. Ipsw firmware iPhone 4.2 beta 3 of 4 (download ).
- The certificate SHSH IOS 4.2 beta 3 (you can notify the rescue via Cydia or TinyUmbrella ).
Once verified these basic requirements, you can proceed with the guide.
Needed
- Redsn0w 0.9.7b6 ( download ).
- OS Mac OS X.
- 4 iPhone updated to 4.2.1 iOS original.
Note: iPhone 3G and 3G (iBoot old) are already running the 4.2.1 Jailbreak Untethered IOS simply using the old version of Redsn0w (0.9.6b4). The new iPhone 3G instead iBoot must of course follow this guide by obtaining the files. Ipsw firmware 4.2.1 and 4.2 beta 3 for iPhone 3G (find links on the net!) And having the certificate of SHSH 4.2 beta 3 saved on Cydia.
Guide
1. First, if you have not already done so, you will need to update your device using iTunes. To do this we connect the iPhone to your Mac using the special cable that are supplied with the phone. Once the device is recognized by the system, you open iTunes. Spostetevi in \u200b\u200bthe "Summary" section and click, hold down the ALT key on the "Restore". Then select, using the appropriate box, the. Ipsw firmware 4.2.1 and proceed with the automatic update of the iPhone. Once the upgrade is complete, you can configure the iPhone using iTunes.
2. Updated iPhone to 4.2.1 iOS, and possibly after the restored backup data (you can still do the jailbreak after you run), run Redsn0w 0.9.7b6 and click on "Browse" and select the file. Ipsw firmware 4.2 .1 that you previously used to update your iPhone. After a few moments, it will be recognized by Redsn0w. Then click on "Next" and proceed. Redsn0w prepare the necessary files for the Jailbreak.
3. Check the only option "Install Cydia" in Redsn0w and click on "Next".
We will be asked to make sure that the iPhone is turned off and connected to your Mac's click on "Next" and prepare to set the device in DFU, we will have to do it (again by phone turned off and connected to the USB )
- Press the Power button for 5 seconds.
- Press the Home button and hold the Power for 8-9 seconds.
- Release the Power button and keep pressing Home for another 3-4 seconds.
- Your device will now be in DFU mode (black screen).
In any case you will be guided by Redsn0w in setting the device in DFU mode.
4. At this point, after entering DFU mode, the process is automatic and Redsn0w run a series of commands, only on Mac first, then also on the iPhone, until you receive a nice pineapple on the device display. Finally, the iPhone will restart in tethered mode and will have been completed the first phase of the operation of Jailbreak. At this point we run again Redsn0w, we follow the same steps listed in Steps 2 and 3, taking care, however, not to tick the "Install Cydia" and activate the other hand, the "Just boot tethered right now." In this way, after you set the iPhone in DFU again (by phone turned off and connected to the USB), it will reboot and you can use Cydia.
5. Now connect your iPhone to your Mac, then open iTunes, and restore the old backup (if you have not already). In any event, even if not reversed, it is very important , if you want to use Skype without crashing and problems once you jailbreak Untethered, verify that the above application is installed via iTunes on the iPhone and is perfectly functional.
6. Redsn0w open again, we follow the same steps set out in section 2 (file selection. Ipsw firmware 4.2.1 and confirmation) and then check off just "Jailbreak Mount." Then select, after you press "Next" file. Ipsw firmware 4.2 beta 3. Confirm the operation and expect Redsn0w recognize the firmware in question (of course everything on the phone is turned off and connected to the USB DFU mode).
7. Again, Redsn0w perform several commands, on both the Mac and the device connected. The procedure, however, may be slightly longer than that of Jailbreak. Recall that the technique "Monte", created by the Dev Team, Jailbreak allows you to switch from one type of semi-tethered, like the one we performed earlier, for an Untethered without having to restore the iPhone. Once the process is complete your iPhone will reboot.
8. We're finished! Now you can enjoy a full Jailbreak, stable and without any problems. The bug in Skype and Bluetooth are in fact completely disappeared. To verify the authenticity of this information, and to realize if you have done correctly or not the operation of Jailbreak, just go into Settings> General and see if the "Bluetooth" is active and can be changed; for Skype, however, simply launch the ' application and verify that it works correctly.
