What are the iPhone death code and Arabic flashback code?

The death code in iMessage, also known as "EffectivePower", is very likely to crash when the user of iMessage is attacked by a string of Arabic characters, because this code will overload the memory load of iPhone, leading to the crash.

Apple said in the update file: H? redundant

Flashback refers to the sudden exit interruption (similar to Windows application crash) when the application is opened in mobile devices (such as iOS and Android devices). Mostly: the application screen flashes by and then returns to the home screen. Application flashback may be due to its own vulnerabilities or equipment problems. Next, let's take a look at the Apple mobile phone flashback repair tutorial.

Method 1: The solution of flashback caused by different Apple IDs.

1. Determine which account downloaded the installed application. (You can view it in the application list of iphone Flashback Repair Tool)

2. Use the "Repair Flashback" function of "iphone Flashback Repair Tool" to repair. Click the "Site Resources" genuine application on the left side of "iphone Flashback Repair Tool", and then select the "Repair Flashback" button that appears on the right side.

3. Click to repair the device flashback function. There are still problems with flashback and AppleID input. Please check whether the PP Assistant (PC) version prompts that the repair is successful.

4. The principle of this method is to eliminate the bug of the app itself. The only reason is that the authorization of the appstor account is invalid. This iphone5 cannot be opened without the account authorization of flashback software. Once opened, it will flash back. Clicking flashback repair is equivalent to authorizing an account for the device and can continue to use it.

Method 2: Flash back due to unauthorized iphone jailbreak.

1. If the IOS device just escaped from prison, try to restart it.

2. Download a free software in the appstore of IOS, which can easily solve the authorization problem! The problem of flashback does not exist. I would like to remind you that iphone jailbreaking is risky, because some plug-ins may cause some applications to be incompatible, which may lead to the situation that it cannot be opened normally.

Matters needing attention

Method 1: If the flashback problem still occurs after the repair.

Method 2: delete the original app software, and then reinstall the app software in the appstore. Delete iphone application: Press and hold the icon of the application to be deleted on the home screen for more than 3 seconds, and the icon will shake. Click the "X" in the upper left corner of the icon to delete the application.
