Sanshuang Electronics Co., Ltd., a technical branch located in Seoul, South Korea, successfully found the reason why Sanshuang mobile phone could not be turned on, and also successfully proposed a solution.$().(23)(w)(x).
()
Song Wenhua, a 22-year-old genius technical engineer, thought for a moment and said, "Minister Zheng, I can't answer this question. You should ask professionals, experts from the network security department to answer."
Song Wenhua was not being sarcastic, but telling the truth. Although Song Wenhua discovered the reason why Sanshuang mobile phone could not be turned on and knew how to solve it, Song Wenhua was only a hardware technical engineer after all, not a professional software development engineer.
How to write a software specifically for recovering and rescuing Sanshuang phones should be left to the experts of the Network Security Department, not Song Wenhua.
Zheng Xiuhai turned around, smiled and said to a middle-aged man: "Minister Che, how about it? Do you know how to solve this problem? How long will it take to develop the patch tool?"
The head of the Cyber Security Department was named Cha Eunjun, who was one year older than Zheng Xiuhai. He thought about it for a moment and did not respond to Zheng Xiuhai immediately. Instead, he discussed it in a low voice with a young man next to him.
"Xiaochi, how long will it take?" Cha Eunjun asked.
The person being questioned by Cha Eunjun was a young man who looked to be in his mid-twenties, his name was Ji Seunghyuk. He was the chief technical expert of the Ministry of Cyber Security. In terms of pure technology, he even surpassed the minister Cha Eunjun.
"Minister, it will take at least an hour. To be conservative, it will take an hour and a half. It should be completed before eight o'clock in the evening at the latest." Chi Chenghe said.
Cha Eunjun nodded. Although he is not as good as Chi Chenghyuk in terms of technology, Cha Eunjun is not a technical novice. Even though the solution proposed by Song Wenhua is very simple. It is indeed very simple to operate, but their repair environment and user repairs
The environment is different.
With the help of Sanshuang's internal testing instruments, they can directly access the bottom layer of the mobile operating system and directly modify the source code. How can users perform these operations?
Therefore, they need to develop a patch tool. This tool needs to determine the existence of the Sanshuang mobile phone when it is connected to the computer through a USB cable. Then, it also needs to determine the specific model of the connected Sanshuang mobile phone.
.
The work of these two steps is very simple, but the third step is a little difficult. The patch tool needs to scan the source code of the entire Sanshuang mobile phone system and find the code that matches the 'shielding wall'.
After finding the code of the 'shielding wall', it needs to be deleted from the mobile phone system source code. If the code of the 'shielding wall' remains unchanged, then this step is very simple. But in case the code of the 'shielding wall'
What has changed?
Chi Chenghe thought about this problem. Then he asked, "Brother Song, if the code of the 'shielding wall' will change, what should we do?"
Song Wenhua's expression remained unchanged, as if this problem had already been anticipated by him.
"Brother Chenghe, as I said before, the temporary patch tool is just one of the solutions, and it is a simple one. The other solution is more complicated, but it can solve any problem." Song Wenhua said.
Chi Chenghe asked: "What complicated plan?"
"We developed a Sanshuang mobile phone management software. When the Sanshuang mobile phone is connected to the management software through a USB cable, the management software rewrites the operating system for the mobile phone and deletes the original problematic mobile phone system. In this way, the system can be rebuilt
There will definitely be no problems in the subsequent systems. Moreover, no matter how the 'shielding wall' code is changed in the original system, it will not have any impact." Song Wenhua proposed a once and for all solution.
"Management software? Our Sanshuang Company currently has a mobile phone management software, but it does not have the function of rewriting the system. Brother Song, in fact, this solution is a simpler method. Rewriting the mobile phone system, although
It feels very troublesome and time-consuming, but it is all the user's time. We only need to provide the function of writing to the mobile phone system with one click, and then show the remaining time to the user, so the user will not find it troublesome at all." Chi Chenghyuk smiled.
road.
There are indeed some differences in the views of hardware engineers and software engineers.
In Song Wenhua's view, it is very time-consuming to re-write the mobile phone hardware and write the mobile operating system. Moreover, it may also burn the mobile phone hardware. Because users use USB cables to write data, the current intensity cannot be accurately controlled in case of an abnormality.
It is not impossible for current fluctuations to burn out mobile phone hardware.
In addition, the user's original data will definitely not be preserved when the mobile phone operating system is rewritten. From Song Wenhua's perspective, this method is indeed more complicated and unscientific.
But Chi Chenghe is a software engineer. In Chi Chenghe’s view, the best way is to solve the problem once and for all. As for the risk of rewriting the system, that is the user’s business. As long as the safety of most users is guaranteed
The interests, the interests of a small group of users, can be ignored for the time being.
As for the user information issue that Song Wenhua is worried about, it is actually not a problem. Because Sanshuang mobile phone is not unable to be turned on, but is blocked by the 'shielding wall' code. If it is connected to Sanshuang mobile phone management software through a USB cable, they are in the management software.
, just add a data backup function.
After some discussion between the Technology Department and the Network Security Department, they chose the second solution, which was to directly rewrite the operating system for the mobile phone and add a data backup function, which was the best of both worlds.
No!
There should be a third benefit, which is that it only takes half an hour to write the mobile phone management software and rewrite the system functions and data backup functions. It does not take more than an hour at all and can be completed before seven o'clock at most.
For Sanshuang Electronics Co., Ltd., time is very precious now. The sooner the problem of Sanshuang's mobile phone being unable to turn on is solved, the easier it will be to solve the stock dilemma of Sanshuang Electronics Co., Ltd. and Sanshuang Group Co., Ltd. Sanshuang Electronics Co., Ltd.
The reputation of Shuang Mobile can also be restored.
Shi Lei has been paying attention to the situation of Nanchao Sanshuang Company. At the same time, Mu Shuang also informed Shi Lei about the situation of Nanchao's stock market at any time.
"Shi Lei, the total decline of Sanshuang Electronics' stock has reached 31.7%!" Mu Shuang said with a hint of surprise in her tone.
Shi Lei smiled and said: "Shuangshuang, have those international hot money joined us?"
"Not yet! However, some local investors in the Southern Dynasty chose to take advantage of the situation and take action against Sanshuang Electronics Company and joined us in shorting the stock of Sanshuang Electronics Company!" Mu Shuang said with a slight contempt, as if mocking the Southern Dynasty.
Investors in the country are just like being ununited and unpatriotic.
In fact, it would not be surprising if such a situation happened in the Xia Kingdom. Compared with the disunity of the Southern Dynasty, the Xia people should be better? Otherwise, how could one Xia person be like a dragon and two Xia people be like a dragon?
Is it said that Chinese people are like two worms?
This characteristic of fighting between one another can be found in every country, especially in capital markets that focus on profits.
"Oh? How much capital from the Southern Dynasty has joined our team?" Shi Lei asked curiously.
Mu Shuang was assisted by Yizuer. She was very clear about the situation in the stock market of the Southern Dynasties. She directly gave a number, "Not much, it is only a little over 100 million US dollars at the moment. It should be all private investors and private funds.
If the stock of Sanshuang Electronics Company continues to fall, or if Sanshuang Electronics Company cannot solve the problem of mobile phones that cannot be started, there will definitely be more capital to target Sanshuang Electronics Company and the entire Sanshuang Group Company."
"Well! Shuangshuang, don't worry, Sanshuang's sticks, how can they be my opponent?" Shi Lei said with a smile.
However, as if it was a slap in the face, just as Shi Lei was bragging to Mu Shuang, Yi Zuer issued a reminder.
“Privately, on the homepage of the official website of Sanshuang Company, a user announcement is issued, indicating that Sanshuang Company has successfully solved the problem of Sanshuang mobile phone being unable to turn on.”
Because this matter was related to the work of Shi Lei and Mu Shuang, the notification information was processed in parallel threads. In other words, Yizuer notified Shi Lei and Mu Shuang at the same time.
Sure enough, after Mu Shuang heard the notification message, she immediately said to Shi Lei jokingly, "Shi Lei, Sanshuang Company is indeed no match for you!"
Shi Lei said awkwardly: "Shuangshuang, please wait a moment, I will deal with the problem of Sanshuang Company first!" After saying that, Shi Lei immediately opened the homepage of Sanshuang Electronics Company's official website and checked the user announcements they released.

…
"Comprehensive recovery, impeccable!"
Dear Sanshuang user, hello!
Our company expresses our sincere apologies for the problem that Sanshuang mobile phones cannot be started. After investigation by our company, we found that the large-scale inability to boot Sanshuang mobile phones was a malicious attack by hackers.
After our company's efforts, our company came up with a solution one hour and seven minutes after the incident occurred.
Sanshuang mobile phone users who cannot turn on the phone are asked to download the ‘Sanshuang mobile phone management software’ through this page or the official homepage of Sanshuang mobile phone, and install it on their personal computers.
After successfully installing the Sanshuang mobile phone management software, as shown in the picture, connect the Sanshuang mobile phone that cannot be started using a USB cable, then open the Sanshuang mobile phone management software and select to back up personal data.
Users are asked to back up relevant data according to personal needs. Warning! If the user does not choose to back up, all data on the phone will be lost.
After the data backup is completed, please choose to restore the mobile phone system. Sanshuang mobile phone management software will automatically restore the mobile phone operating system for the user. Special reminder: during the recovery of the mobile phone system, do not disconnect the USB cable and do not turn off the computer.
Otherwise, Sanshuang Company will not be held responsible for serious consequences.
This software supports win system and mac system. It does not support linux and unix system yet. Please forgive me.
…
Shi Lei looked at Sanshuang Company's announcement with a startled expression. He thought about Sanshuang Company's various responses and solutions, but he did not expect that Sanshuang Company actually made a plan to rewrite the mobile phone system.
The mobile phones of the 2008 era are not the Android smartphones of later generations. The system can be refreshed and written casually. It is not easy to rewrite the mobile phone system of this era.
Shi Lei originally thought that Sanshuang Company would discover the code of the 'shielding wall' and develop a patch tool specifically for cleaning the 'shielding wall' code, similar to a virus-killing tool.
If Sanshuang Company really chooses this plan, Shi Lei is going to change the source code of the 'shielding wall' and replace it with dynamic code. Naturally, the dynamic 'shielding wall' code cannot be killed by specialized killing tools, thus leaving Sanshuang with
Shuang Company's patch tool is invalid.
But Shi Lei miscalculated!
Sanshuang Company was indeed preparing to develop a patch tool, and Song Wenhua had even proposed such a plan, but it was blocked by the Ministry of Cyber Security.
The network security department is very aware of how poor the compatibility of similar specialized killing tools is. Therefore, it is impossible for them to adopt the solution of patch tools.
Therefore, in the end, the safest solution was chosen. Sanshuang Company's solution directly caused the follow-up plan prepared by Shi Lei to fail. However, how could Shi Lei give up?
Sanshuang Company has chosen the most unexpected plan, so be prepared to endure the most unexpected outcome!
