To back up data, you only need to connect your iphone, ipad or ipod touch with a data cable, open iTunes, right-click the device name in the left navigation bar and select "Backup". With iTunes, you can back up contacts, text messages, system settings, game progress and other visible content. Backing up SHSH is to prepare for demotion. Of course, if you decide to use iOS5 GM all the time until October 12th, you don't have to back up SHSH. For the principle and specific method of backing up SHSH, please refer to: How to use TinyUmbrella to back up SHSH files. 2. Three methods to upgrade firmware to iOS 5..1 Method 1: Upgrade through the built-in OTA mode of the system; This is the first time that Apple's iOS device can upgrade its system through OTA. As long as it is in an environment with wireless network, it can download and install the upgrade package directly by setting-general-software update without data cable and iTunes. Open the device information page of iTunes and click the "Update" button in the middle of the page to upgrade the firmware to the latest iOS 5..1 through iTunes.
wireless update method 2 of p>iOS5..1: automatically upgrade through iTunes; Everyone should be familiar with this method. Just open iTunes, go to the device information page, click the "Update" button and wait patiently. Method 3: download the firmware manually, and then upgrade it through iTunes; If the download speed of iTunes is slow, you can also download the iOS 5..1 firmware corresponding to the device to the computer through other channels, and then open the device information page of iTunes, hold down the shift key on the keyboard, click the "Update" button in iTunes, and select the downloaded firmware package to upgrade in the pop-up dialog box.
select the firmware package to be swiped into the device, and then the device will automatically start to update the firmware. Wait patiently until the device automatically restarts, and the firmware upgrade is completed.
iOS5 firmware upgrade is completed. 3. Load firmware in RedSnw .9.9b8 After all the above preparations are completed, decompress the downloaded RedSnw .9.9b8.zip, and double-click the "RedSnw.exe" file to start the jailbreak program. At this time, the already opened iTunes will be automatically closed.
double-click "other" button on redsnw.exe's click interface to enter the setting interface.
enter the setting interface, and click "IPSW select" button in the setting interface to load the firmware file. It should be noted here that although iOS 5..1 is about to be jailbroken, RedSnw .9.9b8 does not support loading the firmware of 5..1, so the firmware file of iOS5 must be selected here to pass the verification.
after selecting the IPSW firmware package and seeing the prompt of "successful recognition", click "ok" to close the prompt and return to the main interface of RedSnw.
after successfully identifying the firmware and returning to the main interface, click the "jailbreak" button.
click the jailbreak button. 4. Select to install cydia. In the operation selection interface, different devices will see different options, but "Install Cydia" is included in all devices and must be installed in jailbreak. If you are not familiar with other options, just check "Install cydia".
tick install Cydia
tick install Cydia. Next, RedSnw will prompt us to connect the data cable of the equipment to the computer, and turn off the power supply to prepare for entering DFU mode.
Prompt information before entering DFU mode In the actual jailbreak process, we found that even in the boot state, you can enter DFU mode and complete the jailbreak by following the prompts. It doesn't matter even if you don't successfully enter DFU mode, just follow the prompts to operate again. 5. Manually entering DFU mode and starting jailbreak manually entering DFU mode needs to be realized by combining ammonium keys. It may be difficult for novices. Don't be impatient, operate in strict accordance with the order and time indicated in the prompt, and you can succeed after several attempts.
press the key combination to enter the DFU mode. key combination steps: (1) press and hold the power key for 3 seconds; (2) Keep pressing and holding the power button and hold down the home button for 1 seconds at the same time; (3) Release the power button and keep pressing and holding the home button. After successfully entering DFU mode, Hongxue will automatically start jailbreaking, and then we can release the home button and wait for it to complete the operation. If the key combination fails to enter DFU mode due to improper operation, Hongxue will pop up a prompt that DFU mode failed. Beginners who fail to grasp the time for the first time may be unsuccessful. Just follow the prompts and try several times.
Failed to enter DFU mode
When "Done" is displayed in the red snow, it means that the computer-side jailbreak operation has been completed, and Red Snow can be closed.
Tips for completing the jailbreak operation on p>RedSnw PC: Here's a tip to share with you. If you perform the combination key operation in the boot state, you can successfully enter DFU mode without looking at the tips in the red snow. The first step is also to hold down the power key until a shutdown prompt appears on the screen.
shutdown prompt: don't release the power button at this time, and hold down the home button at the same time. When the screen is completely black, release the power button and continue to press the home button until Hongxue starts to escape from prison. 6. After waiting for the jailbreak to be completed automatically, the device may have a short black screen, followed by a long string of code scrolling.
The code scrolling in the jailbreak process is finally the classic LOGO of Hongxue: running pineapple. This process will last a little longer, usually about 3-5 minutes.
we don't need to do anything during the whole process of running pineapple LOGO in prison break, just wait patiently for it to be completed automatically. However, if the device stays in a certain interface for more than 5 minutes and there is no change during the period, it may be that the jailbreak was unsuccessful. Don't be nervous, just follow the above steps to operate again. After the jailbreak is completed, the device will automatically restart and enter the main interface. A white icon named "cydia" will appear on the second page of the main screen. Click it to flash back instead of entering cydia.
click the p>Cyida white icon to flash back seven, and then use RedSnw to boot again. Next, start RedSnw .9.9b8 again. You still follow the above steps to load the firmware first, and then you don't have to go back to the main interface. Instead, click Other to enter the setup interface. After loading the iOS5 firmware as before, click the "Boot Now" button to re-boot the device in DFU mode.
Click Boot Now to reboot the device. After entering DFU mode this time, a small pineapple with a bite will appear. Note that this is a small pineapple, not the big pineapple that just ran.
take a bite of the small pineapple and wait for about 2 to 3 minutes. After the device is booted and enters the home screen, you can see the normal Cydia icon.
the p>Cydia icon is displayed normally and can be run here, and the jailbreak operation of iOS 5..1 is initially completed. Eight, after entering cydia to install the necessary patches, you need to install the necessary patches through Cydia. For the specific usage of cydia, please refer to the Cydia source usage tutorial, the essential software for iphone jailbreak. There are many plug-ins and patches in cydia, among which Appsync is a must-have. If you don't install it, you can't use iTunes to synchronize devices.
it should be noted on the main page of Cydia source that Cydia can be started and run normally in the Chinese interface after jailbreak, but it may cause Cydia to flash back when trying to enter text, including entering the address when adding the source and using the search function. The solution is to temporarily switch the system language to English, and then complete all the operations of adding source address and other characters in Cydia at one time, and then switch back to Chinese system. Under the Chinese system, as long as you don't input text, all other functions of Cydia can work normally. Cydia must be installed in Chinese source recommendation: 178 Chinese source: apt.178.com Weifengyuan: apt.weiphone.com iPhone Chinese network (video game bus): Although iphone.tgbus.com/cydia's jailbreak from iOS5 to iOS 5..1 has been very rapid, many users have said that, It doesn't matter to them whether they can escape from prison now, because some functions that need to be escaped from prison before, such as iPad gesture control, have been built into iOS5, and this time iOS 5..1 has also turned on the gesture function for the first generation iPad. However, iOS 5..1 does not solve the problem of excessive power consumption after upgrading the device to iOS5. However, Apple is now preparing to upgrade to iOS 5..2, and it is reported that iOS 5..2 will be online as soon as this week. Finally, I need to remind you that jailbreaking is risky and you need to be careful! In particular, the iphone, ipad or ipod itouch of the Bank of China, which is still under warranty, will no longer enjoy the warranty service after jailbreaking!
