What does it mean that AISI assistant needs a password to download the weather forecast?

I. Preparatory work

1, the original connection data line (this is very important! As will be described below);

2. Choose the best USB interface of the computer (such as the back end of the desktop, and it is not loose);

3. Turn off the screen saver of the computer (this is unnecessary, but because some passwords take a long time to get, I personally recommend it for easy observation);

4. Finally, be patient (generally, it takes much longer to escape from prison by swiping a computer) and have confidence (confidence in AISI's assistant).

Second, get the startup operation of the power-on password.

1. Connect the mobile phone to the computer (ensure that the cable is tight and the USB interface is not loose), and turn on AISI Assistant;

2. Click "Advanced Player" in the "Toolbox" of AISI Assistant;

3. Click "Read device power-on password" in the menu on the right, and AISI assistant will be displayed as follows:

4. Manually enter DFU mode: In order to obtain the boot password, AISI must enter the device's IOS system kernel, so it is necessary to ensure that the device enters and is always in DFU mode (entering DFU mode is the most basic skill that the altar friends must master, and its method is clearly marked by AISI assistant, so I won't go into details)!

Third, the process of obtaining the boot password.

Once the device enters DFU mode, AISI Assistant immediately starts to "get the power-on password"! Display as follows:

At the same time, the mobile phone screen will immediately show the white data in the continuous scrolling:

Through the above picture, I believe that the altar friends should understand why I said that we must ensure "original connection data cable" and "good USB interface" !

Friends just need to think about one question: What is the function of the "power-on password"? Just don't let others operate your mobile phone! This is equivalent to IOS setting a "firewall" for all applications! Aisi assistant must enter the kernel of IOS to get it! In this process, AISI assistant "exchanges" massive data with equipment through USB interface and connecting data cable! Anyone who knows a little about "data transmission" knows that there can be no wrong code in the transmission process! As long as there is one error, it will lead to the failure of "whole package" transmission! Naturally, you can't get the boot password!

A friend will ask: My device can be connected to AISI and can enter DFU mode. Is there any problem with my connection data cable and USB interface? ! This view seems reasonable, but it is all wet:

1, the connecting data line is multi-core, there is actually a capacitor between the core wires, and multi-core is the synthesis of multiple capacitor distributions! Only the original data cable is the "most matching interface impedance" (it is impossible to match the cottage)!

2, so is the USB interface! The USB interface in front of the computer is often used, which will cause looseness and poor contact! This will lead to "interface impedance mismatch"!

So interface impedance mismatch will not affect simple connection and small data transmission! But for the transmission of a large amount of data, it is fatal!

Although young, my major is digital transmission. So, I have these basic professional knowledge!

4. Obtaining the power-on password ended successfully.

In the whole collection process, friends only need to wait patiently without any operation (although the computer can be multi-tasked, I personally don't recommend Tanyou to operate anything else during this period! A computer is a hard thing to define. How many years have you been playing? Who can say you can eat it all! Aisi assistant will automatically work for you! Finally succeeded in obtaining the password! Aisi is displayed as follows:

Because we are doing experiments, we set a very simple password: 1234. Nevertheless, the acquisition time is as long as 4 minutes, 4 1 second! It took me longer to escape from prison by swiping the computer!

In order to verify the reliability of AISI Assistant again, I set a complicated password, and AISI Assistant succeeded again! Display as follows:

This time it's 26 minutes and 53 seconds! Now the altar friends should know why I said: have enough patience and have enough confidence in AISI's assistant. !

Enlightenment from verb (abbreviation of verb)

1, AISI assistant gets the power-on password. Currently only iPhone 3GS and iPhone 4 are supported! IPhone 4S and iPhone 5 are not supported! Because they use A5 processor, the CPU architecture is completely different! Therefore, the altar friends who use iPhone 4S and iPhone 5 should carefully save the boot password! Once forgotten and lost, AISI assistant is helpless at present!

2. AISI assistant obtains the power-on password, and currently only supports "4-digit password"! Tan friends just need to think about it: take the 0-9 10 digit as an example, there are thousands of non-repetitive permutations and combinations of 4 digits (online, it is 3000); And if there is duplication, there will be nearly 10,000 combinations of four digits (online, 9,999)! Tanyou must not set a password exceeding 4 digits! Otherwise, AISI's assistant is helpless at present!

3, AISI assistant is the automatic operation of computer software, without any human factors, there will be no mistakes! The equipment of the altar friends is very different. There will be all kinds of human intervention and operation before reading the password! For example, an altar friend mistakenly believed the online statement and deleted the password file of the IOS system (although the IOS system automatically added this file, the content of the file was completely different)! In this case, can AISI's assistant still handle it? !

Therefore:

(1) Once the password is forgotten, the altar friends should not do any other operations, but use AISI assistant to read it immediately!

(2) If the acquisition fails, first check (cables, USB interfaces, including computers) and report (whether there are other misoperation).
