Sanshuang Electronics Company, a technical branch located in Seoul, Southern Dynasty, successfully found the reason why Sanshuang’s mobile phone could not be turned on, and also successfully proposed a solution.
Song Wenhua, a 22-year-old genius technical engineer, considered it and said, "Minister Zheng, I cannot answer this question. You should ask professionals and experts from the network security department to answer it."
Song Wenhua is not saying the slander, but telling the truth. Although Song Wenhua discovered the reason why Sanshuang’s phone could not be turned on and knew how to solve it. But Song Wenhua was just a hardware technology engineer after all, not a professional software development engineer.
How to write a software specifically used to restore and rescue Sanshuang mobile phones should be handled by experts from the Cybersecurity Department, rather than by Song Wenhua.
Zheng Xiuhai turned around and 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 minister of the Cybersecurity Department is Cha Eun-jun, who is one year older than Zheng Xiuhai. He thought about it for a moment and did not respond immediately to Zheng Xiuhai. + Top + Point + Novel is a low voice to discuss with a young man around him.
"Xiaochi, how long does it take?" Cha Eun-jun asked.
Cha Eun-jun asked about a young man who looked twenty-seven or eight, named Chi Seung-hyuk, who is the chief technical expert of the Cybersecurity Department. He even surpassed Minister Cha Eun-jun in terms of technology alone.
"Minister, it will take at least one hour, and it will take an hour and a half to be more conservative. It will be completed before 8 o'clock at night at the latest." Chi Chenghe said.
Che Enjun nodded. Although his technical aspects are not as good as Chi Seung-he, Che Enjun is not a technical novices. Even if the solution proposed by Song Wenhua is very simple, it is indeed very simple to operate, but their repair environment is different from that of the user.
With the help of Sanshuang's internal testing instruments, they can directly enter the underlying layer of the mobile phone operating system or 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 phone when it is connected to the computer through the USB cable. Then, they also need to determine the connected Sanshuang phone and what model they belong to.
The work of these two steps is very simple, but the third step is a bit difficult. The patch tool is required to scan the source code of the entire Sanshuang mobile phone system and find the code that matches the "blocking wall".
After finding the code of the "blocking wall" you need to delete it from the source code of the mobile phone system. If the code of the "blocking wall" remains unchanged, then this step is very simple. But what if the code of the "blocking wall" changes?
Chi Chenghe considered this question and then asked, "Brother Song, what should we do if the code of the 'blocking wall' will change?"
Song Wenhua's expression remained unchanged, as if this problem had been expected by him.
"Brother Chenghe, I said before, temporary patch tools are just one of the solutions, and it is a simple solution. The other solution is more complicated, but it can solve any problems." Song Wenhua said.
Chi Chenghe asked: "What complicated solution?"
"We developed a Sanshuang mobile phone management software. When the Sanshuang mobile phone connects the management software through the USB cable, it will write the operating system again to the mobile phone through the management software to delete the original problem system. In this way, the system after reconstruction will definitely not have any problems. And no matter how the 'shield wall' code is changed in the original system, it will not have any impact." Song Wenhua proposed a once-and-for-all solution.
"Do you have a management software? Our Sanshuang company currently has a mobile phone management software, but it just doesn't have the function of rewriting the system. Brother Song, in fact, this solution is the simpler method. Although it feels very troublesome and time-consuming to rewrite the mobile phone system, it is all user's time. We only need to provide the function of writing to the mobile phone system in one click, and then show the remaining time for users, and users will not feel troublesome at all." Chi Chenghe said with a smile.
There are indeed some differences in the views of hardware engineers and software engineers.
In Song Wenhua's view, writing to the mobile phone operating system again is very time-consuming. Moreover, it is possible to burn the mobile phone hardware. Because users use USB cable to write data, the current intensity cannot be accurately controlled. In case of abnormal current fluctuations, burning the mobile phone hardware is not impossible.
In addition, by rewriting it into the mobile operating system, the user's original information will definitely not be saved. From Song Wenhua's perspective, this method is indeed more complex and unscientific.
But Chi Chenghe is a software engineer. In Chi Chenghe's view, the best way to solve the problem once and for all is to solve it. As for the risk of rewriting to the system, it is the user's business. As long as the interests of most users are guaranteed, the interests of a small number of users can be ignored for the time being.
As for the user profile problem that Song Wenhua is worried about, it is actually not a problem. Because Sanshuang's mobile phone is not unable to be turned on, but is blocked by the "blocked wall" code. If they are connected to the Sanshuang mobile phone management software through the USB cable, they will add a data backup function to the management software.
After discussing it with the Network Security Department, the Technology Department chose the second processing solution, directly rewrite the operating system for the mobile phone and add data backup functions, which is the best of both worlds.
No!
There should be a third advantage, that is, writing mobile phone management software to rewrite the system function and data backup function, which only takes half an hour, and does not take more than an hour at all. It can be completed before seven o'clock at most.
For Sanshuang Electronics Company, the time is really expensive now. The sooner the problem of Sanshuang mobile phone not being able to be turned on, the easier it is to solve the stock dilemma between Sanshuang Electronics Company and Sanshuang Group. The reputation of Sanshuang mobile phones can also be restored.
Shi Lei has been paying attention to the situation of the Sanshuang Company of the Southern Dynasty. At the same time, Mu Shuang also told Shi Lei about the situation of the stock market of the Southern Dynasty at any time.
"Shi Lei, the stock of Sanshuang Electronics Company has fallen by 31.7%!" Mu Shuang's tone was filled with a surprise.
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 attack Sanshuang Electronics Company and joined us in shorting the stocks of Sanshuang Electronics Company!" Mu Shuang said with a little contempt, as if mocking the investors in the Southern Dynasty. They were not united or patriotic.
In fact, if this happens in Xia State, it is not surprising that Xia State should be better than the disunity of the Southern Dynasty. Otherwise, how could there be a saying that one Xia State is a one-stop and two Xia State are two insects?
The characteristic of fighting in the nest is available in any country, especially in the capital market that focuses on interests.
"Oh? How much capital does the Southern Dynasty have joined our team?" Shi Lei asked curiously.
Mu Shuang has Yi Zuer assisted. She is quite clear about the situation in the stock market in the Southern Dynasty. She directly gave a data, "Not much, it is only a little more than 100 million US dollars at present, and it should be some private investors and private funds. If the stock of Sanshuang Electronics Company continues to fall, or Sanshuang Electronics Company cannot handle the problem that the mobile phone cannot be started well, there will definitely be more capital, and choose to target Sanshuang Electronics Company and the entire Sanshuang Group."
"Well! Shuangshuang. Don't worry, how could Sanshuang be my opponent?" Shi Lei said with a smile.
However, as if it was a slap in the face, Shi Lei just bragged to Mu Shuang, and Yi Zuer sent a reminder.
"Sir, the homepage of Sanshuang Company's official website, issued a user announcement, saying that Sanshuang Company has successfully solved the problem that Sanshuang's mobile phone cannot be turned on."
Because this matter is related to the work of Shi Lei and Mu Shuang, the notification information is a parallel processing thread. In other words, Yi Zuer notified Shi Lei and Mu Shuang at the same time.
Sure enough, after hearing the notification, Mu Shuang immediately said to Shi Lei jokingly, "Shi Lei, Sanshuang Company is indeed not your opponent!"
Shi Lei said awkwardly: "Shuangshuang, 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 issued.
...
"Total recovery, impeccable!"
Hello, Dear Sanshuang user!
Our company apologizes for the problem that Sanshuang’s mobile phone cannot be started. After our company’s investigation, it was found that the large-scale incident of Sanshuang’s mobile phone being unable to be turned on was a malicious hacker attack.

Please back up relevant information according to your personal needs. Warning! If the user does not choose to backup, all information on the phone will be lost.
After the data backup is completed, please choose to restore the mobile phone system. The Sanshuang mobile phone management software will automatically restore the mobile phone's operating system for the user. Special reminder: During the recovery of the mobile phone system, please do not disconnect the USB cable and do not turn off the computer. Otherwise, serious consequences will occur and Sanshuang Company will not be responsible.
This software supports win system and mac system, and does not support Linux and Unix systems at the moment, please forgive me.
...
Shi Lei checked the announcement of Sanshuang Company and was stunned. He thought that Sanshuang Company would make various reactions and solutions, but he did not expect that Sanshuang Company actually made a solution to rewrite the mobile phone system.
The mobile phones in the 2008 era were not Android smartphones in later generations, and the system was free to write. It was not easy to rewrite the mobile phone system in this era.
Shi Lei originally thought that Sanshuang company would discover the code of "blocking walls" and thus developed a patch tool specifically for cleaning the code of "blocking walls", which is similar to the virus-specific killing tool.
If Sanshuang Company really chooses such a solution, Shi Lei will prepare to change the source code of the "Screen Wall" and replace it with dynamic code. The dynamic "Screen Wall" code will naturally not be killed by the special killing tool, thus making Sanshuang Company's patch tool invalid.
But Shi Lei miscalculated!
Sanshuang Company was indeed preparing to develop patch tools, and even Song Wenhua had proposed this solution, but it was obstructed by the Cybersecurity Department.
The cybersecurity department is very clear about how compatible the similar specialized killing tools are. So they cannot adopt the patch tool solution.
So, in the end, he chose the most secure solution. The solution of Sanshuang Company directly made the subsequent plan prepared by Shi Lei still die. However, how could Shi Lei give up?
Sanshuang Company has chosen the most unexpected plan, so you must be prepared and endure the most unexpected ending!
