Many people have the experience of mistakenly deleting data when using a mobile phone, for example, after breaking up with a girlfriend to remove the image of the previous play, the result has not been a few days and compounded, one day girlfriend want to remember a warm moment with you, this time can not get a photo or video will be very embarrassing. In order to avoid this kind of people (Xi) (Wen) drama (Jian), It is necessary to grasp the data recovery technology.Traditional data recovery is often done with software, such as Easy Recovery,recuva. But this kind of software is often powerless for the new Android phone, since a few years ago, most handset manufacturers used the "media device" MTP mode instead of the Large-capacity USB storage mode, While the traditional data recovery software was unable to directly carry out data recovery from the MTP mode loaded mobile phone storage space.therefore, It is necessary to study the data recovery method suitable for the current Android mobile phone, This paper mainly discusses the data recovery of the internal storage space of the mobile phone, the data recovery of the mobile TF card can be done by traditional means, This article is no longer discussed.There are three common methods of mobile phone data recovery at present: the First Method: <blockquote style="margin: 0px; padding: 0px 0px 0px 10px; border-left-width: 3px; border-left-style: solid; border-left-color: #dbdbdb; color: #3e3e3e; font-family: "Helvetica Neue", Helvetica, "Hiragino Sans GB", "Microsoft YaHei", "微软雅黑", Arial, sans-serif; font-size: 18px"> <blockquote style="margin: 0px; padding: 0px 0px 0px 10px; border-left-width: 3px; border-left-style: solid; border-left-color: #dbdbdb; color: #3e3e3e; font-family: "Helvetica Neue", Helvetica, "Hiragino Sans GB", "Microsoft YaHei", "微软雅黑", Arial, sans-serif; font-size: 18px"> Physically disassemble the chip for data recovery. After disassembling and removing the memory chip, the data is recovered after reading the chip data with the hardware Tool. The advantage of this method is that it does not write new data to the memory chip, and it can protect the raw state of the data better. Shortcomings are also obvious, this method of tools and hands-on requirements, a little careless mobile phones and chips have a risk of scrap, ordinary users are more difficult to complete this kind of operation Independently. </blockquote> </blockquote>The second method: <blockquote style="margin: 0px; padding: 0px 0px 0px 10px; border-left-width: 3px; border-left-style: solid; border-left-color: #dbdbdb; color: #3e3e3e; font-family: "Helvetica Neue", Helvetica, "Hiragino Sans GB", "Microsoft YaHei", "微软雅黑", Arial, sans-serif; font-size: 18px"> <blockquote style="margin: 0px; padding: 0px 0px 0px 10px; border-left-width: 3px; border-left-style: solid; border-left-color: #dbdbdb; color: #3e3e3e; font-family: "Helvetica Neue", Helvetica, "Hiragino Sans GB", "Microsoft YaHei", "微软雅黑", Arial, sans-serif; font-size: 18px"> Data recovery with Third-party Tools installed on the PC Side. The most famous Android data Recovery tool on the internet is Wondershare dr.fone,tenorshare-android-data-recovery,7-data recovery Suite software, But the common problem with this kind of software is that Often unable to establish a connection with the phone, or after the scan after the connection failed, may be due to the Android series of mobile phone system customization is high, each handset manufacturer has made more or less changes to the Android system for the sake of the actual effect is not ideal, I believe many friends in this kind of software encountered similar Problems. </blockquote> </blockquote>The third method:<p style="padding:0px; Color: #333333; clear:both; white-space:pre-wrap; Font-family: " helvetica neue", helvetica,"hiragino sans gb", "microsoft yahei"," microsoft ya black ", arial, sans-serif; font-size:18px "> <blockquote style="margin: 0px; padding: 0px 0px 0px 10px; border-left-width: 3px; border-left-style: solid; border-left-color: #dbdbdb; color: #3e3e3e; font-family: "Helvetica Neue", Helvetica, "Hiragino Sans GB", "Microsoft YaHei", "微软雅黑", Arial, sans-serif; font-size: 18px"> <blockquote style="margin: 0px; padding: 0px 0px 0px 10px; border-left-width: 3px; border-left-style: solid; border-left-color: #dbdbdb; color: #3e3e3e; font-family: "Helvetica Neue", Helvetica, "Hiragino Sans GB", "Microsoft YaHei", "微软雅黑", Arial, sans-serif; font-size: 18px"> Recover data with the Android app installed on your PHONE. Because the app runs directly on the phone, there is no problem with the software and phone connection failure in the second method, and the effect of this kind of software recovery depends heavily on the ability of the software developer to use the data recovery algorithm. This kind of software has a lot of, in a digital cleanup master for example, a digital cleanup master's privacy shredding function can scan to the user before the deletion of some types of files, and can indeed be able to restore such files. But there are many shortcomings, there are four main points: one is able to recover the file type is limited, mainly for photos, text messages, call records, etc. second, the photo can only be a single point of recovery, unable to batch recovery, cumbersome operation; third, The data recovery algorithm is not strong enough, Compared with traditional data recovery tools such as R-studio and easyrecovery, there is a small gap; four is that the data can only be restored to the internal storage space of the phone, unable to choose to restore to the SD card, so the original data of the phone is covered by the new recovery data Risk. of course, These shortcomings may be related to the location of the software is privacy shredding rather than privacy recovery, these shortcomings in many similar software also exist, in particular, the data recovery capabilities of many software in this aspect of the function is too weak, the third method due to the existence of many drawbacks also can not be satisfied. </blockquote> </blockquote> 0x01 correct posture for Android phone data recoverySo there is no better method of data recovery, the answer is Yes. In fact, the biggest problem in these methods is that such software is either not available at all or is too weak to Recover. If you can use the powerful algorithms of traditional data recovery tools, This kind of problem will be solved naturally. The following describes a solution that can largely address bottlenecks in the above Approach. In this article, Nubia Z9 Max nx510j as an example, the steps are detailed to take care of readers of different levels as much as Possible.The first step is to enter developer mode and turn on USB debug mode before root,root the PHONE. This is the most basic requirements, how to root and the model of the phone, if you really do not look around the opposite sex it to help people.The second step is to install the BusyBox in the Phone. Suggestions from the official Google download, ladder-owned, the article used in the tool will be provided at the end, lazy Self-pickup. BusyBox can choose the path when installing, assuming that it is installed in [/system/bin/busybox].The third step is to connect your phone to your computer. After the connection, the corresponding driver needs to be installed and can be installed with tools such as Pea pods. Also need to prepare the ADB debugging tools (adb.exe and other files), can be downloaded from the Android SDK website, the root toolkit is also generally available.fourth, Install the 32-bit version of cygwin[c:\cygwin] in your computer, and download Nc.exe and Pv.exe to copy the two files and the Adb.exe,adbwinusbapi.dll,adbwinusbapi.dll that were prepared to [C : \cygwin\bin\] directory.Fifth step, run [C:\cygwin\Cygwin.bat], enter the command in order, enter after the window remains open do not close:ADB forward tcp:5555 tcp:5555 ADB shell Su /system/bin/busybox nc-l-p 5555-e/system/bin/busybox DD if=/dev/block/mmcblk0Sixth step, run again [C:\cygwin\Cygwin.bat] open another window, enter the following command:ADB forward tcp:5555 tcp:5555 cd/ NC 127.0.0.1 5555 | Pv-i 0.5 > Mmcblk0.rawThe progress that should appear on the windowAfter waiting patiently, The [C:\cygwin] directory appears with the Mmcblk0.raw file, which is the size of the Phone's internal storage space, which is the image file of the Phone's internal storage space.The seventh step, open a traditional data recovery tool, because the raw file is the Linux file system format, so need to support the software of this kind of system, after the actual use test found that R-studio and easy recovery can better identify such file format, I prefer R-studio , so take this software as an Example. Load the Mmcblk0.raw image that was just Generated.Scan the UserData part of the image, scan to find all kinds of data deleted by mistake, the girlfriend finally saved:)Using this method, we can make full use of the recovery technology of mature data recovery software, and greatly improve the success rate of data recovery of Android Phone. The actual test found that the number of photos recovered by this method is far more than the recovery of various types of mobile phone data recovery software in the Market. A similar tutorial has been written abroad, but may be not familiar with the data recovery software, after extracting the image and do a lot of superfluous processing, such as the use of VhdTool.exe to the image for various post-processing, not only increased the complexity of the steps, may also play a misleading role.0x02 more thinking The core of this paper is to extract the image of the Android phone, and there are many things that can be done after the image is extracted, for example, by analyzing wpa_supplicant.conf to get to the place where someone often goes and so On. Through this article can be seen, if the elimination of the phone is simply to remove some sensitive files directly to some third-party recycling agencies will be how much risk, so many small videos on the Web how you feel the flow Out. If the lack of basic protection of mobile phone information security awareness, It is necessary to assume the consequences, some of the consequences may be serious to pay a high price.Android Data Recovery
