What are the advantages of mobile phone upgrade?

In order to save development costs, mobile phone manufacturers often build a mobile phone hardware platform with certain upgrade space, and then develop different software, change the appearance and internal parts layout of mobile phones, and adjust some hardware circuits appropriately, so as to easily manufacture a series of mobile phone products with obvious differences in appearance, function, grade and price to meet the needs of different users and markets.

Motorola V2088, V2 188, L2000 (series), V998+/+ and V8088/+ are typical examples. Although they have great differences in appearance, function and price, they all come from the same hardware blueprint, and the CPU level and memory capacity are the same. The key difference lies in the software. As you can imagine, installing DOS6.22 and windows ME system on two groups of computer cores with the same configuration, the former uses the old horizontal chassis and the latter uses the luxurious vertical chassis. The two microcomputers will give people completely different feelings in appearance, control mode and speed. If the DOS system is washed away, replace it with wi.

Ndows ME system, you will also find that there is no substantial difference between the two.

The hardware circuit of V998++ is almost the same as that of V8088, and the software of V8088 can be directly applied to have the powerful functions of V8088. Applying ready-made high-version software on the premise of hardware compatibility is the most commonly used software upgrade method at present. The upgrade is not overclocking, all the reference clock frequencies have not changed because of the upgrade, and the improvement of the machine's function, performance and stability is only due to the characteristics of the new software.

At present, mobile phone software upgrade basically adopts software cloning, that is, reading data from the high-end version of the mobile phone as a whole, and then writing it into the low-end version of the mobile phone for overall upgrade. We know that it is best to delete the hardware configuration table and let the computer reinstall all drivers according to the actual hardware environment when cloning the system of one computer to another computer with ghost software, otherwise the system may be unstable. This problem also exists in mobile phone upgrade. For example, the display components of L2000 are different from those of V8088, and the drivers are not compatible. If the L2000 is directly canned into the V8088 software, the screen will be chaotic and unusable. However, even if V998+ with almost the same hardware as V8088 applies V8088 software, various problems may actually occur. This is because of the hardware of each mobile phone.

There are individual differences in circuit parameters, so it is necessary to use instruments to correct the corresponding hardware control parameters in the software one by one in production. The way of software cloning can't guarantee the rationality of these parameters, which may cause a series of problems, such as: the signal is full but can't be typed (Pacal table mismatch leads to transmission congestion), the received signal is unstable (AGC is improperly set), the radiation becomes larger, and the standby time of the mobile phone is shortened (the battery charging and discharging efficiency becomes lower due to improper battery threshold setting).

With proper modification, the software V8088 can also be applied to mobile phones such as V2088 and L2000. After the upgrade, if you want to reach the technical level of the new licensed products, it is best to use the comprehensive test platform to comprehensively adjust and test the mobile phone. The comprehensive measurement platform with a value of nearly one million can only be configured by individual high-standard customer service centers. The author also achieved very satisfactory results by using interval subsection compensation method.

Mobile phone upgrade to achieve new functions

Have you ever thought about upgrading the software of your mobile phone? In fact, upgrading mobile phone software, just like upgrading a computer from Win2000 to Winxp, can add more new functions on the one hand and eliminate some original problems on the other. The after-sales service of most mobile phones can provide free software upgrades. Consumers should go to the repair center designated by the manufacturer and listen to the suggestions of the staff before transforming their mobile phones. Special note: Be sure to back up the phone number stored in the mobile phone before operation, and all phone numbers will be cleared after upgrade.

Software is the soul of mobile phone.

To put it simply, the memory space of the same brand and the same series of mobile phones is the same, and the huge functional difference lies in the software difference besides the hardware difference! Switching to new software gives new functions to mobile phones, which is the basic concept of mobile phone software upgrade.

As we all know, the functions that a personal computer can achieve mainly depend on the software it installs. In fact, the mobile phone is an ultra-small computer that can process audio and send and receive radio frequency. It also has a CPU, a flash memory used as a hard disk for storing system software (commonly known as "font library"), and a dynamic memory equivalent to memory (commonly known as "temporary storage"). The flash memory capacity of ordinary GSM mobile phones is 2 to 4 megabytes, and the temporary storage capacity is about 1 to 2 megabytes. These chips are mounted on the main board of the mobile phone by SMT in BGA ultra-small package. Without software, mobile phones will become waste. If hardware is the body of a mobile phone, then we can think that software is the soul of a mobile phone.

In order to save development costs, mobile phone manufacturers often build a mobile phone hardware platform with certain upgrade space, and then develop different software, change the appearance and internal parts layout of mobile phones, and adjust some hardware circuits appropriately, so as to easily manufacture a series of mobile phone products with obvious differences in appearance, function, grade and price to meet the needs of different users and markets.

Upgrading the software will bring new functions.

The software upgrade of mobile phone can not only eliminate bugs in the original mobile phone, but also add some new functions. For example, Motorola E365 can achieve "call sticker" through software upgrade, which is not available in its original version; 730 and 680 mobile phones can increase the Internet access and "one-click Internet access" function; V60 and V70 can change the boot screen, not limited to the monotony of the original MOTO logo; There are also some old versions of mobile phones that can add the function of "forwarding short messages". In addition, the usual software upgrade will optimize and improve Chinese character input, and will add some words or association functions that could not be found in the past.

Some software, after upgrading, can bring various new functions, such as N628 mobile phone. When the software version is upgraded from K3+ to A 1, the following changes will occur: 1. K3+ smart pinyin input method does not need to be activated, and some parallel N628 mobile phones are not available when inputting Chinese characters. It is a bug of K3+ software that you have to switch to traditional Chinese and then switch back to smart pinyin to input Chinese characters normally. 2. SMS adds vibration function; 3. There will be no disorder on the screen when surfing the Internet; 4. Cancel the shutdown animation.

Be careful when upgrading software.

Not everyone likes Winxp, which is no better than Win2000 in any way. Some people like to use Win98, others like to use Winxp, which is entirely out of personal preference. The same is true for mobile phone software. Not the latest software must be the best. You should choose which version of software to use according to your own preferences.

The staff of the maintenance center reminds everyone that some mobile phones with short time on the market or complete software have no upgraded version, some upgraded contents are unnecessary for mobile phones, and some functions will take up more memory, so sometimes the upgraded effect is not as good as the original and the running speed is slower, so consumers should listen to the staff's suggestions and think carefully before upgrading.

Indeed, the functions of mobile phones can be said to be mainly controlled and realized through software. Theoretically, we can realize the functions we want through mobile phone software. But in fact, due to the limitation of the hardware resources of the mobile phone itself and the resource environment of the main software framework, the software writing of a mobile phone is a systematic project, involving many aspects, and we can't write and change it at will.

Mobile phone software includes software kernel, modifiable external application and setting menu. Usually, the kernel can't be changed casually. On the one hand, the relevant code is the core secret of the manufacturer and will never be made public easily. Secondly, the change of kernel program often affects the whole body, and a small change will involve a series of resource redistribution. I don't know if you have heard this sentence: removing a software bug may lead to 100 new bugs! For manufacturers, the kernel modification must also be done by expert groups rather than individual programmers, which is by no means possible for ordinary DIY enthusiasts of mobile phones.

In addition, if the consumer's mobile phone has no fault factors, but only upgrades the software version, it is best to go to the maintenance center from Monday to Friday, because there are many people in the maintenance center on weekends, which will lead to a long waiting time.

Skills of upgrading mobile phones

In fact, a mobile phone is a subminiature computer capable of audio processing and RF transceiver. It also has a CPU, a flash memory used as a hard disk for storing system software (commonly known as "font library"), and a dynamic memory equivalent to memory (commonly known as "temporary storage"). It's just that the mobile phone uses a special CPU and has a communication protocol. The flash memory capacity of ordinary GSM mobile phones is 2 to 4 megabytes, and the temporary storage capacity is about 1 to 2 megabytes. These chips are mounted on the motherboard in an ultra-small package. If hardware is the body of mobile phone, software is the soul of mobile phone. So, can you upgrade your mobile phone software?

Theoretically, new functions can be realized by changing the mobile phone software. But in fact, due to the limitation of the hardware resources, software framework and environment of the mobile phone itself, the software programming of a mobile phone is a systematic project, which cannot be changed at will in general.

As we know, mobile phone software includes software kernel, modifiable external application and setting menu. Usually, the kernel can't be changed casually. On the one hand, the relevant code is the core secret of the manufacturer and will never be made public easily. Secondly, the change of kernel program often affects the whole body, and a small change will involve a series of resource redistribution. Removing a bug in the software may lead to 100 new bugs! The modification of the kernel must also be done by the expert group for the manufacturer, and even individual programmers can't do anything about it, let alone ordinary mobile phone enthusiasts.

In addition, some mobile phones with short time on the market or relatively complete software don't have upgraded versions, some upgraded contents are unnecessary for mobile phones, and some functions will take up more memory, so sometimes the effect after upgrading is not as good as before, so consumers should listen to the suggestions of staff and think carefully before upgrading.

At present, mobile phone software upgrade basically adopts software cloning, that is, reading data from the high-end version of the mobile phone as a whole, and then writing it into the low-end version of the mobile phone for overall upgrade. We know that it is best to reinstall all drivers when cloning a computer system to another computer, otherwise the system may be unstable. This problem also exists in mobile phone upgrade. For example, the display components of L2000 are different from those of V8088, and the drivers are not compatible. If the L2000 is injected directly into the V8088 software, the screen will be confused and unusable. However, even if V998++ with almost the same hardware as V8088 uses V8088 software, various problems may occur.

Most mobile phones can get free software upgrade service after sale. Consumers should go to the repair center designated by the manufacturer and listen to the suggestions of the staff before transforming their mobile phones. In particular, the phone number stored in the mobile phone must be backed up before the operation, and all phone numbers will be cleared after the upgrade is completed.
