You must pay attention to many problems, such as mobile phones that contain personal privacy. , or be careful, otherwise all privacy will be restored in minutes! ! Of course, this is what happened. There are still some potential dangers. I don’t need to talk about it. The reprint is to warn everyone that if you don’t want to scrap it, or resell someone else’s mobile phone, you should pay attention to destroying the data. It won’t take long. Time, but there is a certain guarantee for the protection of your privacy data and personal safety. Let's take a look at what is going on!
As a happy subordinate machine program èŒ + Meng Duo hardware siege lion + extraordinary adjustment consultant, I think it is necessary to tell you: the phone is not, or broken, do not litter, otherwise it is like this Meng Same as sister paper. . . . Fortunately, she met a happy lower computer program èŒ + Mengxiao hardware siege lion + extraordinary adjustment consultant, I am lively and smart, naughty and sensitive, free to live in the green forest ...... well, it’s far away. Why can’t we throw the bad mobile phone in the end, let us look down with the lens of the landlord.
First of all, we came to the crime scene. This is a bad mobile phone that Xiaobian got on the roadside. How bad is it? First of all, the shell is gone, not only the shell is gone, the screen is gone, the battery is gone, and even the back cover is not a few meanings? Ok, this is a broken mobile phone circuit board that can't be turned on, only one motherboard left, and the motherboard has been repaired by others.
What can this broken board do? I can't do it on the front, so we flipped to the back of the board, as a joyful machine program èŒ + stunned hardware siege lion + extraordinary adjuster consultant, I saw that this chip is a come from The most powerful cosmopolitan country in the universe, the eMMC flash memory chip produced by Samsung, we checked the model and learned that the chip is 16GB memory. That is to say, this mobile phone is a mobile phone with 16GB memory space, and some mobile phones are alive. But it is dead, some mobile phones are dead, but it is still alive, it is this mobile phone motherboard, well, then let Xiaoqi come to save it.
First of all, this black box is from Samsung's eMMC chip, model is KLMAG2GE4A - A001, has 16GB internal memory space, belongs to eMMC 4.41, 169-ball BGA package.
Since the pad of the chip is very small, it is soldered with a very thin, very fine, very fine, very thin and very thin wire. Here, a copper wire inside the earphone cable is used to separate the mobile phone chip.
The eMMC chip is simply a flash memory chip with integrated controller. Simply put, you can use it like a memory card through a card reader. At this time, you need to connect the corresponding pins on the chip to the card. On the device, the following is the pin diagram of the chip, we need to connect DAT0, DAT1, DAT2, DAT3, CLK, CMD, VCC, GND to the corresponding pins of the reader.
This is a card reader with Chinese characteristics, and its connotation is self-understanding.
This is the pin definition map of the TF memory card.
Remove the card holder's card holder, and then connect the chip to the cable, and connect the pin of the memory card to the pad of the card reader to separate the phone chip.
Plug the card reader into the computer, the computer can recognize it, indicating that the chip wiring is not connected correctly, you can see that there are a total of 9 partitions, of which the first 8 are Android system partitions, used to store Android system data, virtual memory partitions, etc. The one behind 11.26GB is the user partition, which is the place to store data for you. Now, we have to do something that is so shocking, that is, data recovery for this 11.26GB partition.
Come here, good play, Cuihua, sauerkraut, isn’t it, it’s data recovery software. First of all, I’m not a privacy voyeur. I’m just doing this to tell everyone that a bad phone can’t be littered. It’s a kind of Things that are socially charitable should be applauded by everyone, not to peek at the photos inside, although I have already seen them. ..
Let's see it, let's see it, and know why bad phones can't be littered!
Of course, some data has been destroyed, but by analyzing the damaged photos, you can also know that this phone is Sony Ericsson's LT22i. This damaged photo was taken on February 5, 2014, at 12:20. In 52 seconds.
Of course, she met a kind-hearted, kind-hearted, happy subordinate machine program èŒ + savvy hardware siege lion + extraordinary adjustment consultant, so I not only did not do bad things, but also helped her All the remaining data is destroyed. As a compensation, this chip is owned by me, all the partitions are deleted, and then used as a USB flash drive.
The speed is not bad, the write can reach 17.3MB / S, but the official data given by Samsung is that the maximum write is 35MB / S, the read is 80MB / S.
Data recovery conclusion:
This bad board is from the Sony Ericsson LT22i phone
The owner of this mobile phone is a student at Guilin XXX College, 20XX's cute sister paper.
This cute girl paper may already be working now, maybe her or her company is at XXX
