Android system mobile phones have been very popular in the market, but many ordinary users are still confused when they hear the word android mobile phone and don’t know what kind of mobile phone it is. In fact, to put it simply, Android is an emerging smart phone operating system. The native system was developed by Google. We refer to mobile phones equipped with the Android smart operating system as Android phones. Currently, many mobile phone manufacturers are producing smartphones equipped with the Android system, including HTC, Motorola, Samsung, Sony Ericsson, LG, Huawei, Acer, OPPO, Meizu and many other well-known domestic and foreign manufacturers.
Root permissions: Root permissions can be understood as the same concept as our administrator permissions under the Windows system. Root is the super administrator user account in the Android system. This account has the highest rights in the entire system and can perform any operation in the system. In order to prevent software from changing system files, the Android system hides root permissions. However, we usually use Root permissions to modify some system files or operate certain software. When we flash and install the system on our Android phones, we also need Root permissions. Yes, after obtaining and enabling root permissions, we can perform any operation at will.
Flashing: Flashing is a professional term for mobile phones. It refers to changing or replacing some languages, pictures, ringtones and software versions or operating systems inherent in the original system of the mobile phone through certain methods, which can make the mobile phone functions More complete. Flashing can be official or unofficial. Simply put, flashing an Android phone is equivalent to reinstalling its system, which is similar to our common computer system reinstallation.
APK: APK is the abbreviation of Android Package, which is the Android installation package. It is the file format of android mobile phone programs. This is similar to the sisx, sis, and jar formats of Nokia mobile phone programs. They are all a format of installation package files. Transfer the program in apk format to the mobile phone. Through the file management software, click on the format The file can be installed, or you can use a data cable to connect your phone and computer, and install it through an installation assistant program on your computer.
Desktop widget: The simple literal translation of Widget is component, widget, and gadget. In an Android phone, when you press and hold a blank space on the desktop for a few seconds, a dialog box will pop up with the option to add a desktop widget. This is the added desktop widget. Users who have used Windows Vista or Windows 7 should be familiar with desktop widgets. Computers also have the function of adding some widgets to the desktop. The desktop widgets in the Android system are also similar to them. By adding widgets to the desktop, you can It is very convenient and quick to perform some searches and operations.
Recovery: Recovery means recovery when translated. As the name suggests, this is a recovery mode on your mobile phone. Through this recovery, users can install the system (the so-called flashing), clear various data on the phone, partition the memory card, backup and restore, and many other functions. It is similar to the Ghost one-click recovery on the computer. Friends who have installed the system on the computer may know that if there is a problem with the computer, or if you want to change to a new system, the easiest way is to use Ghost to reinstall the system. Just simply It's done with just a few clicks of the mouse. The same is true for recovery mode on Android phones.
wipe: Wipe translated means erasure, erasure, etc. There is a wipe option in recovery mode. Its function is to clear various data in the phone, which is similar to restoring factory values. We most commonly use wipe before flashing the phone. You may see a prompt that WIPE is required, which means clearing the data before flashing the phone. Be careful to back up important things in the phone before wiping.
ROM: ROM is the English abbreviation of Read Only Memory. Generally speaking, ROM is the operating system of android mobile phones, similar to computer operating systems, such as Windows xp, Windows7, etc. We usually say to reinstall the computer system, just get a system CD or image file and reinstall it. The same principle applies to flashing Android phones. The ROM package is rewritten into the phone through flashing. The ROM is the system package on the Android phone.
WIFI: The power of an Android phone lies in its network function. When you get an Android phone, you may find that it is connected to the network all the time, and there are many powerful network software on the Android phone. , it is not enough to rely solely on the mobile network of the mobile phone. The wifi network of the android mobile phone can make up for these very well, and the function is very powerful.
Wi-Fi is a technology that can connect terminals such as personal computers and handheld devices (such as PDAs and mobile phones) to each other wirelessly. In layman's terms, WIFI is a wireless networking technology. In the past, computers were connected through network cables, but now they are connected to the Internet through radio waves. The most common one is a wireless router, so it can be used within the effective range of the wireless router's radio wave coverage. WIFI connection is used for networking. If the wireless router is connected to an ADSL line or other Internet line, it is also called a "hotspot".
IPL, SPL: The full English name of IPL is InitialProgramLoader, which is responsible for the motherboard, power supply, hardware initialization program, and loading SPL into RAM. If the IPL is damaged, you can throw the phone into the river or change the font to solve the problem.
The full English name of SPL is SecondProgramLoader, "second system installation", which is responsible for loading the OS operating system into RAM. In addition, SPL also includes many system commands, such as the commands used in mtty. If the SPL is damaged, it can be rewritten with a writer.
SPL generally provides these functions: detecting mobile phone hardware, finding system startup partitions, starting the operating system, and providing an operating interface for basic maintenance of the system. It can establish a connection with an operating terminal (such as a PC) through a data cable. and accept and execute corresponding orders. It contains many commands, such as r2sd, l, doctest (dangerous command, it will erase gsmdata), etc. The three-color screen we often talk about is driven by SPL. Detect the SD card. When you insert some specially made SD cards, SPL can verify at startup and flash or execute some commands based on the contents of the SD card.
This is somewhat similar to booting from a floppy drive on a PC.
IPL and SPL versions can be viewed on a three-color screen. Press and hold the camera button, then briefly press the power button to enter the three-color screen to view relevant information.
CID, SUPERCID:
CID is the abbreviation of CustomerIDentity.
Simply speaking, it is the platform version of the mobile phone. The CID after XX restrictions is called SUPERCID.
During the flashing process, SPL needs to verify whether the ROM is available based on the CID and decide whether to flash it. Generally, the ROM must correspond to the CID before it can be used. ROMs with different cids cannot be flashed. For ordinary CID, there are generally two restrictions:
1) You cannot flash a lower version of ROM,
2) You cannot flash a ROM of a different platform,
p>
For example: flashing European version ROM on Taiwan version, flashing ROM across models, etc.
SUPERCID The CID restrictions of some models of mobile phones can be XX through software. The known ones are 577W, 586W, etc.
But there are also some models for which there is currently no effective method. XXCID, such as 838G4.
The cid after the XX restriction is called SUPERCID.
A machine with a SUPERCID can flash ROMs of any version and platform.
Specifically, the same mobile phone can be flashed with Taiwanese ROMs,
it can also be flashed with Japanese ROMs, Hong Kong ROMs, etc.
You can even flash the ROM of another mobile phone model (such as 586W flashing 577W).
But this also brings great danger, because there are no restrictions and no verification.
It is also very easy to flash a wrong ROM.
We generally need XX to be SUPERCID when flashing, because on the one hand, in most cases now the ROM used for flashing cannot pass the CID verification;
On the other hand, in case of flashing Failure is easier to fix for SuperCID phones.
RADIO: Radio is simply the driver of the wireless communication module.
ROM is a system program, and Radio is responsible for network communication.
ROM and Radio can be refreshed separately without affecting each other.
If your phone has communication problems after refreshing the ROM, you can try refreshing RADIO.

Starting from HTC Hero, all products launched by HTC will integrate HTC Sense.
And conforms to three design concepts, including Make It Mine, Stay Close, and Discover the Unexpected.
Recovery: Generally speaking, it is a flash engineering interface.
If you have installed a system, you may know the dos interface or winPE.
Installing Recovery is equivalent to installing a dos interface for the system.
In the recovery interface, you can choose to install the system, clear data,
ghost backup system, restore the system, etc.
There is no conflict between flashing recovery and flashing rom.
Root:
Root permissions can be understood as the same concept as our Administrator permissions under Windows system
.
Root is the super administrator user account in the Android system.
This account has supreme rights over the entire system, and he can operate all objects
. Only with this permission can we refresh the original system to various modified systems,
such as the Simplified Chinese system.
APP TO SD, APP2SD: Some Android machines install the program on the machine memory by default when installing the program.
This will cause the originally small memory to be occupied and run. The speed is reduced and the memory card utilization is very low.
APP TO SD means installing the program to the SD card to free up phone memory and increase running speed.
The same goes for APP2SD, it’s just a homophone.
Sign: Sign refers to signing the Rom package or Apk application.
Only signed Rom or Apk can be flashed or installed on the phone.
Cyanogen, CM: Cyanogen is a talented foreign person. The CyanogenMod series of Rom produced by it is relatively popular.
The main pursuit is speed. The abbreviation of CyanogenMod is CM, so it is also common among us. CMROM.
adb: adb is the abbreviation of Android Debug Bridge, which means the debugging bridge of the Android system.
Through adb, we can debug Android programs through DDMS in Eclipse.
In fact, this is the debugging tool used for Google Android system.
The working method of adb is quite special. It uses the method of monitoring Socket TCP 5554 and other ports to allow IDE and Qemu to communicate.
By default, adb will use daemon-related network ports, so when we The adb process will run automatically when you run the APK installer.
In addition to the above operation functions,
We can also manage the status of the device or mobile phone simulator through adb.
You can also perform many mobile phone operations, such as flashing ROM system upgrades, running shell commands, etc.
