San Shuang Electronics, located in Seoul, South Korea, successfully found the reason why San Shuang's phone could not be turned on. They also successfully proposed a solution.
Song Wenhua, a 22-year-old genius technical engineer, thought for a while and said, "Minister Zheng, I can't answer this question.
You should ask the professionals, the experts in the network security department can answer. "
Song Wenhua was not being sarcastic, but he was telling the truth.
Although Song Wenhua found the reason why San Shuang's phone could not be turned on and knew how to solve it.
But Song Wenhua was only a hardware technical engineer, not a professional software development engineer.
How to write a software to save San Shuang's phone should be handled by the experts in the network security department, not Song Wenhua.
Zheng Xiuhai turned around and smiled at a middle-aged man, "Minister Che, how is it? You know how to solve this problem, right?
How long will it take to develop the patching tool? "
The minister of the network security department was called Che Enjun. He was one year older than Zheng Xiuhai. He thought for a while and did not answer Zheng Xiuhai immediately. Instead, he whispered to a young man beside him.
"Xiao Chi, how long will it take?" Che Enjun asked.
The young man who was asked by Che Enjun was a 27-year-old man named Chi Chenghe. He was the chief technical expert of the network security department. In terms of technical skills, he was even better than Minister Che Enjun.
"Minister, it will take at least one hour, one and a half hours, and it will be finished by eight o 'clock at the latest," Chi Chenghe said.
Che Enjun nodded. Although he was not as good as Chi Chenghe in terms of technical skills, Che Enjun was not a technical noob.
Even if Song Wenhua's solution was simple and easy to operate, their repair environment was different from the user's repair environment.
With the help of San Shuang's internal detection equipment, they could directly enter the bottom layer of the phone's operating system and directly modify the source code.
How could the user do these operations?
Therefore, they needed to develop a patching tool. This tool needed to determine the existence of San Shuang's phone when it was connected to the computer through a USB cable.
Then, they needed to determine the model of the connected phone.
These two steps were simple, but the third step was a little more difficult. The patching tool needed to scan the entire source code of San Shuang's phone and find the code that matched the 'shield wall'.
After finding the code of the 'shielding wall', it needs to be deleted from the phone's source code.
If the code of the 'shield wall' remained unchanged, then this step would be easy, but what if the code of the 'shield wall' changed?
Chi Chenghe considered this problem and asked, "Brother Song, if the code of the 'shield wall' changes, what should we do?"
Song Wenhua's expression did not change. It seemed that this question was within his expectations.
"Brother Chenghe, as I said before, the temporary patch tool is only one of the solutions, and it's a simple solution.
The other plan is more complicated, but it can solve any problem. "Song Wenhua said.
Chi Chenghe asked, "What complicated plan?"
"We've developed a San Shuang phone management software. When a San Shuang phone is connected to the management software through a USB cable, the management software will rewrite the phone's operating system and delete the phone's original system.
In this way, there would be no problems with the rebuilt system.
Moreover, no matter how the code of the 'shield wall' is changed in the original system, it will not have any effect. "Song Wenhua proposed a solution that would solve the problem once and for all.
"Management software?
Our San Shuang company has a management software, but it doesn't have the function of rewriting the phone's operating system.
Brother Song, in fact, this plan is the simpler one.
Although it is troublesome and time-consuming to rewrite the phone's operating system, it is the user's time.
We only need to provide a one-button rewrite function and then show the user the remaining time. The user will not find it troublesome at all. "Chi Chenghe said with a smile.
Sure enough, the hardware engineers and software engineers had different opinions.
From Song Wenhua's point of view, rewriting the phone's operating system was time-consuming.
Moreover, it might even burn the phone's hardware.
Because the user used a USB cable to write data, the power of the current could not be controlled accurately. If there was an abnormal current fluctuation, it was not impossible to burn the phone's hardware.
Moreover, rewriting the phone's operating system meant that the user's original information would not be saved.
From Song Wenhua's point of view, this method was indeed more complicated and unscientific.
But Chi Chenghe was a software engineer. From his point of view, solving the problem once and for all was the best solution.
As for the risk of rewriting the phone's operating system, it was the user's problem.
As long as the user's benefits were guaranteed, the benefits of a small number of users could be ignored temporarily.
Song Wenhua's worries about the user's information was not a problem.
It was not that San Shuang's phone could not be turned on, but it was blocked by the "Shield Wall" code. If they used a USB cable to connect to San Shuang's phone's management software, they could add a data backup function in the management software.
After the technical department and the network security department discussed for a while, they chose the second solution, which was to rewrite the phone's operating system and add a data backup function. It was the best of both worlds.
No!
There should be a third benefit. Rewriting the phone's management software and rewriting the system and data backup function only took half an hour. It did not need more than an hour. It could be completed before 7 pm.
For San Shuang Electronics, time was very precious. The earlier they could solve the problem of San Shuang's phone not being turned on, the easier it would be to solve the stock problems of San Shuang Electronics and San Shuang Group.
San Shuang's reputation could also be saved.
Shi Lei had been paying attention to San Shuang's situation in Nan Chao Nation. At the same time, Mu Shuang also told Shi Lei about the situation in Nan Chao Nation's stock market.
"Shi Lei, San Shuang Electronics' stock has fallen by a total of 31.7%!" Mu Shuang's voice was filled with surprise.
Shi Lei smiled and said, "Shuangshuang, did the international hot money join us?"
"Not yet!
However, some local investors in Nan Chao Nation chose to take advantage of San Shuang Electronics and joined us in shorting San Shuang Electronics' stock! "
Mu Shuang said with slight contempt, as if she was mocking the investors in Nan Chao Nation for not being united and not being patriotic.
In fact, if such a situation happened to Xia Xia, it would not be surprising at all.
Compared to Nan Chao Nation's disunity, Xia Xia's people should be more outstanding, right?
Otherwise, why would there be a saying that one Xia Xia was a dragon, and two Xia Xia's people were two worms?
Internal strife was a trait that existed in any country, especially in the capital market that valued profits.
"Oh?
How many investors in Nan Chao Nation have joined us? "Shi Lei asked curiously.
Mu Shuang had Izur's help, so she was very clear about the situation in Nan Chao Nation's stock market. She directly gave him a number. "Not much, only a little more than 100 million USD at the moment. They should be private investors and private funds.
If San Shuang Electronics' stock continues to fall, or if San Shuang Electronics cannot solve the problem of not being able to start the phone, there will definitely be more investors who will choose to target San Shuang Electronics and the entire San Shuang Group. "
"Mm!
Shuangshuang, don't worry. How can San Shuang and those guys be my opponents? "Shi Lei said with a smile.
However, just as Shi Lei was bragging to Mu Shuang, Izur gave him a notification.
"Sir, San Shuang Electronics' official website has released a user announcement, saying that San Shuang Electronics has successfully solved the problem of not being able to start the phone."
Because this matter was related to Shi Lei and Mu Shuang's work, the notification was processed in parallel. In other words, Izur notified Shi Lei and Mu Shuang at the same time.
Sure enough, after Mu Shuang heard the notification, she immediately teased Shi Lei. "Shi Lei, San Shuang Electronics is indeed no match for you!"
Shi Lei said awkwardly, "Shuangshuang, wait for a moment. I'll go and deal with San Shuang Electronics' problem first!"
After saying that, Shi Lei immediately opened the front page of Sanshuang Electronics' official website and looked at the user announcement.
…
"Full Recovery, Impeccable!"
Dear San Shuang users, hello!
Regarding the problem of not being able to start San Shuang's phone, our company would like to express our sincere apologies.
After our company's investigation, we found out that the incident of not being able to start San Shuang's phones on a large scale was a malicious attack by hackers.
After our company's efforts, we came up with a solution one hour and seven minutes after the incident happened.
Please download the 'San Shuang Electronics Management Software' from this page or the official website of San Shuang Electronics and install it on your personal computer.
After successfully installing the software, as shown in the picture, connect the unbootable San Shuang Electronics with a USB cable, then open the software and choose to backup your personal data.
Please backup the relevant data according to your personal needs.
Warning!
If the user does not choose to backup, all the data will be lost.
After the data backup is complete, please choose to restore the phone's operating system. San Shuang Electronics Management Software will automatically restore the phone's operating system for the user.
Special note: During the restoration of the phone's operating system, please do not disconnect the USB cable and turn off the computer.
Otherwise, San Shuang Electronics will not be responsible for any serious consequences.
This software supports Win and Mac systems, but not Linux and Unix systems. Please forgive us.
…
Shi Lei looked at San Shuang Electronics' announcement and was stunned. He had thought that San Shuang Electronics would react and solve the problem, but he did not expect that San Shuang Electronics would come up with a plan to rewrite the phone's operating system.
The mobile phones of the 2008 era were not like the Android smartphones of the future. The operating system of the mobile phones in this era was not easy to rewrite.
Shi Lei thought that San Shuang Electronics would discover the code of the 'shield wall' and develop a patching tool to remove the code of the 'shield wall'. It was similar to a virus killing tool.
If San Shuang Electronics had chosen this plan, Shi Lei would have changed the source code of the 'shield wall' to a dynamic code.
The dynamic code of the 'shield wall' would not be destroyed by the anti-virus tool, so San Shuang Electronics' patching tool would not work.
But Shi Lei had miscalculated!
San Shuang Electronics had planned to develop a patching tool. Song Wenhua had even proposed this plan, but it was blocked by the Network Security Department.
The Network Security Department knew very well how bad the compatibility of such anti-virus tools was.
So, they could not use the patching tool.
So, in the end, they chose the most reliable plan.
San Shuang Company's solution directly killed the follow-up plan that Shi Lei had prepared before it was even born.
However, how could Shi Lei possibly leave the matter at that?
Since San Shuang Electronics had chosen the most unexpected plan, they had to be prepared for the most unexpected outcome!
