WM cell phone system terminology explained

1. What is unlocked, permanent unlocking

To unlock, simply explain it, PPC machines in the factory's time machine internal core of CID address section is locked, the principle is based on Microsoft for open WM system provides a privileged protection mechanism, the mechanisms for applications to access system resources for the limit, manufacturers, and this can be exploited by the system ROM lock, lock the aim is to a distinction between the different models and greater independence, because security manufacturers on the WM system innovation, autonomy, locking is concentrated in the machine, the CID addresses different CID ROM are not interactive replacement, if forced flush CID different ROM, will not be able to validate, serious CID will present system beyond repair, this PPC play machine \ "quack" \ "are made up articles, derive a CID addresses deceptive tactics to locked to crack, crack the CID of CID flush, and then brush into different ROM CID will greatly possible through validation (but not 100% are possible) to write a new ROM machine.

Permanent unlocking, rivers and lakes, also known as SuperCID, this new cracked CID and above compared with greater advantage of the new ROM for flush operation, if the operation fails, the system will not be affected by a major injury, even if the resulting damage is also very easy to fix, so we often call this unlock enable PPC "has a bad body".

2、ROM，RAM，Flash Memory

ROM (Read Only Memory) the full name is read-only memory, is part of the hard disk on the PPC to store and save data. ROM data cannot update, but you can read at any time. Even if it is off, the ROM will also be able to retain data. But after a while writing data can only be used in a particular way or no change, ROM often in embedded system as a storage operating system that uses RAM (Random Access Memory) full name to random storage memory, is a PPC on the mobile storage section, used to store and save data. It in no time you can read and write, RAM usually as an operating system or other running program of temporary storage media (called system memory)

Flash Memory, because the ROM is not easy to change the properties so that updates become quite cumbersome, so have the development of Flash Memory, Flash Memory has the ROM does not need power to maintain the benefits of the information, and in need of any change of information that we have common FLASH Memory TF card (full name: TransFLash card), SD card (full name: Secure Digital Memory Card), CF card (full name: Compact Flash card), etc.

3、XIP，IPL，SPL，RADIO

XIP (Execute In Place) Chinese meaning: immediate implementation. XIP the role is to let the operating system kernel to run directly in Flash, you do not need to be copied to RAM, is the operating system or application directly from the non-volatile memory, thus reducing the kernel from the Flash memory are copied to the RAM of the time, its use of non-compressed image also reduces the amount of time the kernel self-extracting, in other words, the XIP directly determines the PPC system operation and loader, also is to directly determine the PPC system run faster.

IPL (full name: InitialProgramLoader) Chinese meaning: first time loading system, which is responsible for the motherboard, power supply, hardware initialization procedures and SPL mounted RAM, if damaged, due to the IPL cannot load the SPL, the machine will not be able to mount any SPL completed loading OS System. SPL (full name: SecondProgramLoader) Chinese Italy: second loading system, which is responsible for loading the operating system OS to RAM, SPL damaged we can burn machine such device to write again, or you can flush the original ROM version to achieve the overriding SPL, we commonly known as "looking for the original ROM save brick"

RADIO, literally understood: radio communications, responsible for the PPC as mobile communication features, functionality, including its telephone and Internet access features, in fact, the RADIO hardware modules have the phone shipped already built, we flush is a software application level, because the software level things determines the RADIO hardware modules receive and transmit signals in frequency bands allocated, so the description of the hardware RADIO has been deprecated, we turn this RADIO software level stuff are called RADIO.

4, brush, brush ROM RADIO

Brush ROM, means that the new ROM flush on PPC, ROM section contains: the IPL, SPL, OS, EXTROM, RADIO, STORAGE, etc., in the meantime, we flush the vast majority of the ROM that contains only some part of the OS, OS contains two things: XIP, IMGFS, which is the main system level, in the light of other factors, since core level involved rewritten, can be overridden, so we had to abandon, to easy, but also reduces the risk of one-time flush. Brush RADIO, simple that is flush with new RADIO module application software, different regions, different communication services network, the wireless base station to receive and send a wireless signal on the band, so in this

Regions and the communication service network within the RADIO hardware modules, in-band adjustments on the more local base stations, mobile phone signal would be better, signal receiving and sending the more complete and more rapid, signal search on more stable so that our PPC signal strength and power, operator new RADIO is based on the base station's new band to adjust, so over time, when the base station has upgraded its band adjustments, new RADIO's flush is necessary.

5. restart, hard restart, fixed screen, robustness, panic

Restart, everyone knows the problem, and PC restart mechanism is the same, the data in ROM is good, but save all the data in RAM is lost, therefore, can be solved by restarting does not operate normally in RAM, such as system running panic, such as the module cannot be found, most of the machines are within a certain time reset operation, not because of power failure, but because the machine run time will have a considerable number of garbage cache in RAM, this is because we frequently operate the machines, we all know, the less you remaining RAM, the machine running the space available, the smaller, the speed of the machine will be slower, less power consumption increases, then restart the machine in the shutdown of the moment, all the data in RAM is lost, including the system garbage, after rebooting, the system will reload the application when RAM is a relatively clean space. Restart the way we all know that even my Earth people know, through the power key, the system application, through the barrel of PP.

Hard restart, and reboot the same need to reboot the machine, the difference is hard reboot will lose any ROM and RAM, and restart only missing RAM, a hard restart after system will automatically restore to its original state, all set to do it again, all the information you want to copy into it, looks like a key on the PC restore mechanism; hard restart principle is to use the machine itself is formatted, the difference is in the ROM format after the machine has an initial data will be transferred out again, this initial data has been present in ROM, you cannot delete, even if you were replacing modified, and so on, seemingly have modified data, not only is the system temporarily hide, then format the hard restart, restart after the ROM machine initial data will be loaded by mediation. Hard restart operations in general we do not commonly used, unless the system ROM in an unrecoverable error causes the machine is not working properly, and that only through hard reboot to repair your system, how hard restart knows Earth, press and hold the hangup and receive two hard press 1234 PP bucket, or clear the memory.

Fixed screen, as the name implies, the screen will stay intact regardless of your operation, PPC will screen in the phenomenon mainly refers to the third screen (or two), normally post as the system load after the splash screen will skip step by step until you see the interface, but because the ROM production errors in or omissions that result in new ROM after the splash screen flush jump over, no matter how long you wait for the phone screen, hold it motionless, unable to enter the system, causing the brush machine fails, the reason explained for screen is because behind solving difficult diseases where this word is used.

Robustness, also known as sleep, non-real panic, death phenomenon is the machine on the surface, is operating normally, but the background of some applications can't be fired, for example, in the standby mode the phone call screen not displayed no ringing tone, for example, in the operation of a program when an excited transient response or reaction without delay is too long.

Panic, everyone knows that this is not to say.

Formatted camera: shutdown state, press and hold the volume up + volume down, press the power key until the picture appears hammered, English prompts, release and hold the volume up and down keys and then press the volume up to begin hard restart, press the other key to quit
