HK1486 Fully Restored and Flawless?
.
Samshuang Electronics Co., Ltd., a technical branch located in Seoul, South Korea, successfully found the reason why Samshuang mobile phone could not be turned on, and also successfully proposed a solution.
Song Wenhua, a 22-year-old genius technical engineer, thought about it and said, "Minister Zheng, I can't answer this question. You should ask professionals. Experts from the network security department can answer it."
Song Wenhua is not speaking ironically, but speaking the truth. Although Song Wenhua discovered the reason why Sanshuang's mobile phone could not be turned on, and also knew how to solve it. But after all, Song Wenhua is just a hardware technical engineer, 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 in a low voice with a young man next to him.
"Xiaochi, how long will it take?" Che Enjun asked.
The person being questioned by Cha Eunjun was a young man who looked to be in his mid-20s. His name was Ji Chenghyuk. 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 was not as good as Chi Seunghyuk in terms of technology, Cha Eunjun was not a technical novice. Even if the solution proposed by Song Wenhua is simple, it is indeed very simple to operate. But their repair environment is different from the user's repair environment.
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 is it possible for a user to perform these actions?
Therefore, they need to develop a patch tool. This tool needs to determine the existence of Sanshuang mobile phone when it is connected to the computer through a USB cable. Then. It is also necessary 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 more 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 for the ‘shielding wall’, it needs to be deleted from the source code of the mobile phone system. If the code of the 'shielding wall' remains unchanged, then this step is very simple. But what if the code for the ‘shielding wall’ changes?
Chi Chenghe thought about this problem and then asked, "Brother Song, if the code of the 'shielding wall' will change, what should we do?"
Song Wenhua's expression did not change. It seemed that 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 operating system is rewritten for the mobile phone through the management software. The original problematic mobile phone system is deleted. In this way, the system is 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 the simpler method. Rewriting the mobile phone system, although It feels very troublesome and time-consuming, but that 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 is possible to burn the phone hardware. Because users use USB cables to write data, the current intensity cannot be accurately controlled. In the event of abnormal current fluctuations, it is not impossible to burn the mobile phone hardware.
In addition, if the mobile phone operating system is rewritten, the user's original data will definitely not be saved. From Song Wenhua's perspective, this method is indeed more complicated and less scientific.
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 interests of the vast majority of users are guaranteed, the interests of a small number 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 the Sanshuang mobile phone is not unable to be turned on, but is blocked by the "shielding wall" code. If it is connected to the Sanshuang mobile phone management software through a USB cable, they will add a data backup function to the management software.
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, that is, 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. The reputation of Sanshuang mobile phones 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 Company's stock has reached 31.7%!" Mu Shuang said in her tone. With a sense of 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 take action against Sanshuang Electronics Company, and joined us in shorting the stock of Sanshuang Electronics Company!" Mu Shuang said with a slight disdain, as if mocking the Southern Dynasty. country’s investors. It's the same as not being united and not being patriotic.
In fact, it would not be surprising at all if such a situation happened in Xia Kingdom. Compared to the disunity of the Southern Dynasties, the people of the Xia Kingdom should be better? Otherwise, how could there be a saying that one Xia person is a dragon and two Xia people are two worms?
This quality of fighting between nests can be found in every country. Especially in the profit-focused capital market.
"Oh? How much capital from the Southern Dynasty has joined our team?" Shi Lei asked curiously.
Mu Shuang was assisted by Yizuer, and 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 some 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 has those 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, Yizuer issued a reminder.
"Sir. On the homepage of the official website of Sanshuang Company, there is a user announcement stating 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 jokingly to Shi Lei, "Shi Lei, Sanshuang Company is indeed no match for you!"
Shi Lei said awkwardly: "Shuangshuang, wait a moment, I will deal with the problem of Sanshuang Electronics first!" After saying that, Shi Lei immediately opened the homepage of Sanshuang Electronics' official website and checked the user announcements they released. .
…
"Full recovery, impeccable!" 》
Dear Sanshuang user, hello!
Our company expresses our sincere apologies for the problem that Sanshuang mobile phone cannot be started. After our company’s investigation, 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 requested to back up relevant data according to personal needs. warn! If the user does not choose to back up, all data on the phone will be lost.
After the data backup is completed, the user is asked to 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: Do not disconnect the USB cable and do not turn off the computer during the recovery of the mobile phone system. Otherwise, Sanshuang Company will not be held responsible for serious consequences.
This software supports Win system and MAC system, but does not support Linux and Unix systems. 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. The dynamic 'shielding wall' code naturally cannot be killed by specialized killing tools, thus rendering Sanshuang's patch tool ineffective.
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. So it is impossible for them to adopt the patch tool solution.
So, in the end, we chose the safest option. Sanshuang Company's solution directly killed the follow-up plan prepared by Shi Lei. However, how could Shi Lei give up?
Sanshuang Company has chosen the most unexpected plan, so be prepared to endure the most unexpected outcome!
