Since the mobile phone system is a ROM, why can it be flashed?

RAM and ROM of the phone

RAM is composed of the initials of Random Access Memory, which means random access memory, that is, it can read and write data to the memory at any time under normal working conditions. According to the working principle of the memory cell, RAM can be divided into static memory (SRAM) and dynamic memory (DRAM). Features of RAM::

readable and writable; When the memory is powered off, the data stored inside is lost. We often talk about memory, such as computer memory, mobile phone memory, including the cache used in the CPU, all belong to RAM memory. ROM is composed of the initials of Read Only Memory, which means read-only memory.

As the name suggests, this kind of memory can only be read and cannot be read and written at any time like RAM. It only allows one write opportunity after it has been produced, and the data cannot be changed once it is written. Another feature of the memory is that the data inside the memory is not lost after the power is off, and it can be stored for hundreds of years.

This kind of memory is mostly used to store firmware, such as the boot program of the computer startup, the corresponding program of some electronic products such as mobile phones, MP4, digital cameras, etc. To sum up, RAM refers to the memory of the mobile phone, and ROM refers to the memory that stores the firmware of the mobile phone, such as the operating system of the mobile phone, some applications such as games, etc.

ROM can only be erased by specific means, RAM can be done on weekdays.

ROM is the abbreviation of ROM Image (read-only memory image), which is equivalent to a system image file of the computer reinstallation system, and the ROM on the mobile phone is simply a mobile phone system, which is usually called flashing the system and brushing the ROM.

ROM is divided into official ROM and third-party ROM according to the type, the official ROM is officially released, with official signature verification, and can be flashed through Android's built-in recovery mode; Third-party ROMs are artificially modified on the basis of official ROMs, which can add many functions that are not available in official packages, and cannot be flashed through the official REC mode, and you need to flash a third-party REC before you can flash a third-party package.

Brush ROM is to brush firmware,It's just that it's customary to call the firmware ROM.,Why care so much about it?,As long as you understand.,All mobile phones in the Android system can be flashed.,It's just that some mobile phones don't have firmware brushes.。

Flashing ROM is what is known as flashing firmware. Well, some mobile phone hardware can't be reached, so you can't brush it.

The commonly known ROM is the firmware, and you don't have to pick too many words.

1 memory, for software.

2. The ROM of the flashed machine refers to the system version.

Satisfactory answer: kiss goodbye under the starry sky level 3 2012-06-02Like my Huawei c8650 can be brushed Huawei c8850, in fact, as long as the mobile phone configuration is not much different, you can brush each other's ,...But it is still necessary to say that "flashing is risky,...Follow-up:"The configuration is not much different"Which range does it refer to is a simple mobile phone configuration? Is there a mobile phone brand included?

Not included, brand ,...As long as the configuration and performance of the two mobile phones are about the same, there is no problem ,...You can just look at the configuration of these two phones, wow....For example, ram...cpu...etc

Okay, ask another question, why is my phone memory and ROM including memory card still have a lot of space, but I can't install the software, prompting that there is no space, only a part of it can be installed. What is the problem? Does it have anything to do with RAM or ROM?

RAM is running memory, so it's impossible, ROM is a flash package, do you install the software on the phone or on the memory card, you go to the settings....Applications....Preferred installation location....Select "Detachable SD card" and try to install it Follow-up question: I use pea pods to operate, and all of them are installed on the SD card, so it's weird. Answer:

Then I don't know hey, you can change a few more roms....Or call customer service to ask

No.

Some ROMs can be used interoperably, but there are cases where they are not fully compatible, which may cause them to freeze or freeze. So for the sake of stability, it's better to flash the ROM of the adapted model.

Of course, if you are skilled in flashing, you might as well try it, and if it is unstable, then brush it that suits your model.

Like my Huawei C8650, you can flash Huawei C8850, in fact, as long as the mobile phone configuration is not much different, you can brush each other's ,...But it is still necessary to say that "flashing is risky,...

No, the models are similar but the parameters, resolution, CPU, and network system can be said to be 100% bricks.

Some brands are the same, and the hardware is basically the same, and they can be brushed with each other, such as Coolpad E239 and Coolpad D530

ROM is an abbreviation for read-only memory, which cannot be changed and can only be read, such as system files;

What we usually call flashing is flashing the kernel ROM of the system.

The superuser of the system is generally named as the only superuser in the system, with all the permissions in the system, such as starting or stopping a process, deleting or adding users, adding or disabling hardware, etc., but most users can not identify the specific role of the program, if the system crashes due to accidental deletion, or can not be used and started, so the first business generally will not let the user directly obtain root permission here.

The functions of flashing are: 1. Update the system version, new operation mode, new interface, new support function; - But the upgrade also has a negative effect, there may be errors, the mobile phone cannot be used, most of them are small horses and carts; Do a good job of backing up;

2. Explore and seek innovation, use enough, and hope to change the style;

Adroid is now relatively easy to get root, you can delete some Facebook, Google and other unused programs; SuperOneClickRoot is relatively simple;

Flashing the phone is risky, be sure to back it up and read the tutorial well, otherwise the phone may become a brick.

Flashing is brushing ROM, and ROM is equivalent to the computer system. Root is the highest permission to get the phone, and you can't delete and change system files without permission. Flashing a computer is similar to installing a computer system.

If you're Saipan, that's the Saipan Forum. There are many Android forums, such as Android forums. Android has a lot of one-click flashing software:

Pure hand hit:

The vernacular is the easiest to tell you.

ROM is a variety of systems--- such as XP on the computer, Win7, the difference is that ROM is Android system in the final analysis, but the focus of each ROM is different, some ROM is beautiful, some ROM is power saving, some ROM is novel, and some ROM is smooth.

Root is to hack the permission of your phone, if you want to flash the root of the phone is a must to do, just like you want to go into the house to get something, you must open the door first.

You can only flash the ROM if you are rooted

Flashing forums I often go to are Jifeng Forum--- Android Forum--- Magic Fun Forum--- MIUI Forum---

Most of the people who like to toss and like to flash are mainly concentrated in these major forums.

If you are satisfied with the answer -- please select me as the ROM question and I will answer it as long as you ask.
