Question 9: How to clear Huawei P6 before brushing, what is double clearing and what is double clearing Huawei P6:

Double clearing actually refers to clearing the cache data and system program data of the mobile phone, usually referring to the formatted /data partition and /cache partition.

Why do you want to clear Huawei P6?

In fact, refreshing the phone is to reinstall the operating system. During the refresh process, the APK program and system framework in the original system will change. We know that the data structures generated by different APK programs are different, which leads to the data compatibility problem of different versions of programs. In order to prevent the newly refreshed system program from being incompatible with the data generated by the original system program, we all need to refresh the system twice before brushing Huawei P6 refresh package.

Consequences of not clearing Huawei P6:

Above, we discussed why we need to double clean Huawei P6 system. There is no double cleaning, which will cause the system to get stuck in the boot screen after brushing, and the system cannot boot to the desktop. Some can't even enter the boot screen, and the phone restarts indefinitely. I have personally tested this for many times, and some can access the system, but the system program will report an error.

How to clear Huawei P6;

1. Official resumption:

Boot into recovery mode, with the following two lines:

Erase data/factory reset

Erase cache partition

Usually, the oil man thinks that double clearing means that the above functional instructions are run once each. Actually, the former formats two partitions, /data (program data) and /cache (system cache), while the latter formats only /cache, so only the first line of functional instructions needs to be run before brushing, and the second line is usually only used to release cache space.

2. Third-party recovery based on CWM:

Now the first line of CWM's double erasure, namely erasure data/factory reset, is different from the official recovery. It formats not only /data and /cache, but also /sd-ext and /sdcard/. Android _ security. I believe many white people don't realize this. This is a complete double-clearing!

In fact, the principle of double clearing is that after clearing the /data partition and the /cache partition, click mounts and storage to enter the menu, execute format /sd-ext, and then enter the sd card to delete all the data. Android_secure directory, which is the only way to achieve real double clearing.

-mount/system mount/ system partition (system partition)

-Load/Data Load/Data Partition (Data Partition)

-mount/cache mount/cache partition (cache partition)

-mount /sd-ext mount/SD-ext partition (A2SD partition)

-formatboot formats the kernel partition.

Format system Format system partition.

-formatdata format data partition

-format cache formats the cache partition.

-format sdcard format memory card (format SD card, use carefully)
