Software part:

1. Download p2kdrivers_2.9 for L7 mobile phone and install it on the computer. If it is already installed in the computer, there is no need to reinstall it.

2. Download P2Ktools_0.8.6 This software is a portable application and does not need to install the Chinese version. You can use it after downloading and decompressing.

Hardware part:

1, one computer, one L7 mobile phone and one mini USB cable.

2. Mobile phone settings: enter the main menu/Settings/Connection /" USB settings in turn, and set the default connection as data/fax connection. Click "Connect Mode"/"Select AT Mode" in the upper left corner of the interface, and another interface of P2KTools operation interface-AT mode interface will pop up. You can click on various options to preliminarily check and understand its contents. It should be noted that in the "P2K" mode, after the software is connected to the mobile phone, don't click the "Mute All" item casually, so as to avoid unintentional operation that will mute incoming calls, messages, alarm clocks, etc. This will affect your daily life (except when necessary).

The function of each option in the operation interface is not explained in detail here, but the following contents will be involved step by step.

Ok, please connect your computer and mobile phone with a data cable. At this time, click the "P2K Mode" option of "Connection Mode" (Figure 4), and the connection between the P2K mode interface and the mobile phone will be automatically activated (the "connected" or "disconnected" status is displayed in the lower left corner of the interface) (below, we will officially enter our happy journey.

Third, backup (download), delete and upload files.

Many mobile phone players want to "slim down" L7, load audio and video files and wonderful pictures, delete and upload the mobile phone panel, and backup the mobile phone files. All these operations need to use the upload, download and delete functions of P2KTools.

(a), backup files

1. Open the file management item (this item is usually opened by default). 2. Click the "Refresh" item in the "File Operation" column, and the software will start reading the file list of the mobile phone (Figure 5).

3. At this time, the letters A, C and B appear in the File List column, and the files under the specified disk root directory appear on the right side of the interface). Special emphasis: Before clicking "Refresh" to read the file list of mobile phone, please ensure that the "Search" item in the "File Operation" column is not checked, otherwise only a drive letter A will appear in the "File List" column. Take backing up the ringtone (audio file) of disk C as an example: enter the audio folder of disk C, and all audio files will appear on the right. 5. Select all files with the mouse, right-click and a file operation dialog box will appear, and click "Download" (Figure 8). You can also click the corresponding item 6 in the "File Operation" column. The Backup Destination Folder Settings dialog box appears. Select the previously created Audio folder and click OK (Figure 9). This backs up the ringtone file of L7. The principle of other file backup operation steps is the same, please operate by yourself. Emphasize that it is very important to make a good backup, because it is likely to be used in the future.

(2), delete the file

The previous operation steps are the same as "backup file", but the difference is in the fifth step: click "download" instead of "delete" (3) to upload the file.

Suppose we delete the ringtone file of L7, and now we need to restore the backup file or upload a new ringtone file, then we need:

1. Open the file management item (this item is usually opened by default). Click the "Refresh" item in the "File Operation" column, and the software will start reading the file list of the mobile phone. 3. In the "File Operation" column, check "Upload Path", click the drop-down arrow in the input box, select the corresponding item, change the default drive letter of the path to "C", and then click ". Many mobile phone players are willing to delete useless files in their mobile phones to expand their memory space (referred to as "slimming"), but some files are protected and cannot be deleted by the deletion program that comes with their mobile phones. Now you can use P2KTools to realize your wish. Of course, the file backup and upload function of P2KTools is also extremely practical.
