*3370#(*efr#): Turn on the enhanced full price function of efr. #3370#(#efr#): Turn off the efr enhanced full price function. *4720#(*hra0#): HR enhanced half-rate function can be turned on. #4720#(#hra0#): Turn off HR enhanced half-rate coding.
*#92702689#: production date (*#0000# query system software update date).
*#746025625(*#sim0clock#): Turn off the sim card clock (mainstream SIM cards in the market support this function, and the battery saves more than 30%. To release the hibernation mode, you need to set it to display the clock in the clock function option, enter the time, and then enter the year, month and day).
#7370#: Format the standby mobile phone to restore it to the factory status (after this instruction is issued, the mobile phone will give a warning, press "Yes", and it will ask for the mobile phone lock code, initially 12345. Then it will automatically shut down and enter the format state, with background light and the words "Nokia". Wait 1-2 minutes until the formatting is completed when the backlight is not turned off and the mobile phone has no other response. Then the phone will ask you to enter the time, date and so on. Make sure the phone is fully charged. Never turn off the power or unplug the battery at this time, otherwise it will refresh the mobile phone software or damage the hardware! )。
*#2820#: Inquire about the Bluetooth chip address of 6600 Bluetooth (each Bluetooth device has a unique address). Formatting method when the system crashes and can't enter the standby screen: If your system is damaged and can't enter the standby screen, but you can see the "NOKIA" boot screen when you start it, you can format the system forcibly in the following ways to restore the normal operation of the system. Press and hold the dial key, "*" key and "3" key at the same time and turn on the power until the word "NOKIA" appears. No keys can be released during this process). Wait a few seconds until "Format .../Format ..." appears, and then release the key. After a few minutes, the system is formatted and the phone automatically restarts to enter the standby screen. This process generally requires two people to cooperate to complete.
Detailed analysis of 6600 internal documents
6600 adopts symbian's open system s60 platform. We can use the 6600 just like a computer. After installing seleq or file man, we can manage its internal resources clearly, conveniently and quickly. It is basically similar to the computer management method. In order to play 6600 better, we should know the internal files of 6600 and the system files of win98. Let me help you get a preliminary understanding.
After installing seleq, enter drive C, and the main folder is C: \ nokia; C:\system。 Among them, Nokia stores some pictures, ringtones, short films and its own games. One folder to note here is c:\nokia\installs. This folder stores the anti-installation files of games and software installed on the mobile phone. If you want to save the space of c:\, you can cut all the anti-installation files in this folder into e:\system\ under installs. In addition, you can delete the pictures that come with your mobile phone, which can save about 40k space. You can also delete the contents of your own game file c:\nokia\game, which can save about 30k space.
What we need to know in detail should be the folder c:\system. This folder is equivalent to the system folder of the mobile phone. There are several folders to be aware of: applications, data, libraries, mail, programs and favorites. 1.apps is where we install software and games. It's all their program files. If we need to crack them, we need to overwrite the corresponding cracked files for Chinese software and games. Applications and Chinese files. Rsc app and rsc file with corresponding software (installed on mobile phone). 2.data is a data folder, where some data on the mobile phone is stored. Notepad file of common phone book file: c: \ system \ data \ contacts.cdb.6600 can be directly backed up as follows: c: \ system \ data \ notepad.dat.realone playback record can be directly backed up as follows: c:\system\data\mediaplayer.dat, which can be directly deleted. 3.libs Here are some software link files and library files. Try not to move. Otherwise, it will cause software errors. 4.mail is a folder for storing short messages. If you want to format your mobile phone without losing SMS, just back up this folder directly. After formatting, just overwrite the new mail with the backup folder. 5. Some software is stored in the 5. Program, and will remain in the memory after startup. These softwares will start automatically when they are turned on. If deleted, some software will not start automatically after booting. 6. Favorites Favorites folder C: \ system \ Favorites \ Xx.lnk records the location and name of files added by shortcut keys. There is another file on drive C, that is, c:\system\mmcstore, which will be automatically generated after your mmc has set a password. This is a password reserved file. When we forget the password on mmc, we can open this file through text and we can see the password. If your mmc has a password, we'd better make a backup of this file. In case of external problems, these folders are basically what we need to pay attention to. I hope you can know more about it.
D: Disks are mainly buffers for surfing the Internet, so don't bother to get rid of them.
This is our mmc. It's about the same as C:. The main folder is system, and some specific purposes in this folder are the same as those in C. It should be noted that if you bring a card machine, you'd better empty the e:\system\sw_autoexec folder first. Because this folder is automatically started after power-on, if it is not empty, users with card machines may not be able to enter the menu normally.
Z disk is the solidified system information. When we upgraded the machine, we changed the information inside.
I'll write it to you in detail after the specific use analysis. For 6600 software, the file management software must be installed first. There are three softwares, seleq, fileman and smartfileman. Most people use seleq, but I recommend fileman. First, fileman takes up less memory space than seleq; second, it supports the use of shortcut keys (one-click copy, cut and paste in place); third, it lists the inbox separately, so you don't have to look for it yourself. But fileman doesn't have to change attributes (like hidden and read-only files) to delete files, which can be said to be both a good thing and a bad thing. If you don't know much about files, it's easy to delete system files by mistake. But smartfileman is useless. Not recommended. In fact, it is very easy to install these three files with a card reader. Just copy the decompressed file directly to the others folder on the mmc card. Then open the file management program of the mobile phone and click Install directly to see that there is no other complication (this is the simplest method). Then you can install the memory management software. There are appman, stacker, taskman and spacedoubler. The function of taskman is 1, which is convenient for setting shortcut keys. The four directions of the rocker can be defined as four practical functions. 2. Terminate the programs running in the background. 3. Compress the memory (the effect is average). 4. Set automatic keyboard locking. Appman's function is to manage the running program, free the running memory, and set the application as binding. The function of stacker is to release the running memory, compress the installed application and set the application as binding. Space multiplier and stacker have similar functions. It is recommended to install stacker here, because it is relatively stable compared with other software, and it can compress the installed applications (especially for mmc card space shortage).
Next, I read e-books. The most classic is smartviewer 1. 1. Advantages: short and pithy, only 28k, you can turn pages back and forth very quickly. At the same time, it supports key page turning (3 and 9). Disadvantages: every time you read a new book, you have to re-select the code of gbkgb12345 Hz gb2312big5, and the book can only be stored in. Followed by qreader 1.39, but only in small font. Large fonts are garbled, and it is easy to garble when turning pages. Rollback is its achilles' heel. qreader can only use the joystick, not the key (rollback has a special key, which is very fast).
Then read m2.03 smartmovie must be installed to watch movies in and support full-screen playback. Avi format. Mobiclipplayer is also good, but it supports. Mo format (this film format is still relatively rare online). The key is to watch flash animation. Funinhand also needs to be installed. Watching TV online is him. Although he said that he now supports Internet radio, I only tried the Voice of West Lake, but I couldn't turn it on. (Hehe, now we have unlimited traffic for 50 months), but I think this software should be monthly, and the second is to have a good gprs network signal, otherwise it will be buffered for 30 seconds. There are agilemessenger (supporting icq, msn, aol, yahoo, jabber) or qq.sis, qq.jar in online software. It's best to install qq.jar, so you can display Chinese without installing additional fonts. I think the best online software is opera, which supports comprehensive formats. Basically all web pages can be opened in full screen. I used him on the 6600 forum, but it is better to have opera on the mobile phone, because the Chinese version of opera is not very good. It's good to install dorisbrowser without your own opera. In fact, netfront is good, fast and supports all formats, but it does not support Chinese websites. The only advantage of webviewer's web browsing is that it is short and pithy, only 50k, unlike opera's 800K, but it is difficult and troublesome to open 6600 forums. There are two folders c: \ Nokia \ inside: images images _ TN for Installing other sounds: all pictures can be deleted, TN is a thumbnail, and the transmitted sis files are all empty sounds regardless of whether install is empty or not: if it is empty, it is important that the software installed after system: c: \ system \ apps \ will be installed in this folder, which is equivalent to "program file" applnst. The ini is on the C drive of the computer. The size of the installed software will change after this file, which mainly records the information of the installed software. The important profileapp\dbprofile.db 3kb will change after this file. The database mainly records the information of installing software. seleq, an important program of systemexplorer, can be seen that the function of seleq is equivalent to the function of "My Computer" and ie of the computer. That's all the initial contents of c:\system\apps\ If you use seleq to change the operator logo, there will be multiple phones \ OPLOGO \ 460 _ 0 _ 0. Bmp7kbc: \ system \ bootdata \ commondata.d00,65438+7b This file will never change. Firstboot.dat 0b This file will always be 0. I deleted this file, let me enter the time and date after restarting, and come back after checking it. Add this file: simlanguage.dat 4b, upload it to your computer and view it in Notepad. The content is 3 1. It is estimated that 3 1 defines the sim card language, which means simplification, just like the following localedata. The extension of d3 1 is 3 1, which corresponds to haldata.dat 16b. Localedata.d3 1 70b will never change. C:\system\data\ This is a very important folder. I will write it in detail here. Please be careful when deleting. There are two files in \cbs. Cbs0.dat size 7 1b will never change, cbs 1.dat has changed, and its function is unclear. \saveddecks is related to network services, and the content here is empty at first. \wapstore is a stored webpage or cached application. dat is a program data record, and the important bookmark. db is used as a bookmark. The file size of btstate.dat recording wap address will change, and its function is unclear. Cacerts.dat is a certificate that you should check when installing software. The certificate allowed at the beginning of Nokia is a calendar here, and the initial size is 365b cntmodel.ini, which is related to business cards. Contacts.cdb is a business card file! Logdbu.dat records communication records, including telephone calls, gprs traffic, etc. Mrouteragent.ini and mrouterclient.dat record the setting parameters of the connection between the mobile phone and the computer (I use infrared), and maybe modify some data items to optimize the connection more carefully. Later, I slowly studied the size of nitz.dat After opening it, I found that there was only one character "1" in it, and the function was unclear. The initial sizes of wapreast.dat and smssegst.dat are both 59b, and the names must be related to SMS. Template.n3 1, with an initial size of 558b, the specific function is unclear, but it must be related to the language and geographical location settings. Dat, with an initial size of 59b, knows the S60 system related to wap, and saves space skillfully (take NOKIA6600 as an example). Since you want to use Fat Six, you must first understand the format supported by our Symbian system and the working principle when installing software. Symbian system support: *. Sis (installation file of standard Symbian OS operating system) *. App (usually decrypted file) *. Jar (usually Kjava software or games) *. Exe (the most is the registrar, as long as the IMEI number of the mobile phone is input, a string of numbers will be generated and input into the mobile phone. That software is the full version. Jad (installation path file, now there is generally no *. Txt (mostly software introduction and use, with E) *. Html (mostly software introduction and usage, as well as the home page link of its software) *. Pdf (mainly software introduction and use, with E) *. Nfo (usually the introduction of the decryptor, handwritten version). Sometimes it includes the registration code of the software) *.bk 1 (software backup data will include the registration information of the software) *. Rsc (the program resource file of the operating system, which is now generally a Chinese file, can be completed by overwriting the source file with SeleQ or FileMan). Now the most common software formats are SIS and JAR. The first is SIS. During the installation process, the system installs \system\apps\ in c(e) (this is equivalent to the "program file" of the computer), and generates an anti-installation file \system\install\ in C(E), and its anti-installation icon is orange in "Program Management". Click the view properties to see if it is in Symbian OS format. The decompressed Kjava file is not directly installed in C(E):\system\apps\, but first installed in C(E):\system\MIDlets\, and then a corresponding startup icon is created in C(E):\system\apps\Registry\ (equivalent to the computer's start menu file). Installing software or games on a mobile phone is just a simple process of decompressing and copying files to the corresponding directory. Generally, the installation file is transmitted to the mobile phone (or memory card) first, and then the installation program is executed in the mobile phone. However, when installing these programs in Symbian system, you need to first decompress the files into the storage space of your mobile phone, and then copy the decompressed files to the installation path you set. This is the most common problem: when installing games or software, the system always prompts that the storage space is insufficient, but if you look at the use of MMC card on the mobile phone, there is obviously a lot of available space. This makes many novices puzzled. Because in the decompression process, if the storage space of your mobile phone body is insufficient, the decompression process will not be completed normally, and the system will jump out of the warning of "insufficient space". Even if there are hundreds of megabytes or even G space in your MMC card, it is useless. After understanding the installation principle, let's further compress the available space of the fuselage. The software I use is SELEQ. I installed the simplified Chinese version of SeletQ v 1.65 in order to use the MMC card normally. Generally speaking, every time I install a software or game, I will generate an anti-installation file with the same name as the installation file under c:\system\install\, which is usually in SIS format, but the SIS file here cannot be run directly. The function of these files is to let the "program management" of the mobile phone identify the installed software and provide the function of direct deletion. Although it is a humanized design method, many friends like to download e-books to their mobile phones. Over time, there are more and more e-books in their mobile phones. However, as soon as you open "Program Management", the problem comes: a lot of anti-installation directories pop up, and it takes several minutes to open "Program Management". Then, delete an e-book and wait a few minutes to refresh the table of contents. Dizzy! How long will it take to delete all of them? An hour? Two hours? Are all the birds asleep, big brother? In fact, users can completely ignore the design of the system, and all files in the c:\system\install\ directory can be deleted! And will not have any impact on the installed software! You can use SELEQ to enter the directory and delete all the contents, so as to get more C disk space. But the deleted software will not be listed in the "program management" list of the mobile phone, so how to delete the software? It's simple. If it is installed in the fuselage, go directly to c"\system\install\ to find the folder of the corresponding software and delete it. Similarly, delete it in e "\ system \ install \ installed in MMC card". By the way, our fat six is Symbian 70, and the system has been changed compared with Symbian 60. If users install software in MMC, the corresponding anti-installation files will appear in e:\system\install\ instead of C drive, so they are not as nervous as C drive. Of course, for the sake of space, you can also delete their anti-installation files. For example, the anti-installation files of e-books are all in c(e):\system\install\Registry\ You can delete this folder directly, but only if other JAVA programs are not installed. For example, my TMQQ is installed in a memory card, and I found it in the e: system \ apps \ [101ba748] \ folder with SELEQ, but I can't find which is its anti-installation file. When I want to delete its uninstall file, I should go to E: System \ Apps \ [65438] and find "[10 1ba748]". Txt file ",click" edit file "to view it, and you will see:" TM E: \ system \ midlets \ [101653ac] \ 20041041. JAR "This is the storage location of its jar file. Note "[10 1653ac]" in this address, which is its folder name in the anti-installation directory, and go to E: \. Also, a few games, such as some NG games, even if they are installed on E disk, a folder with the same name as E disk will still be generated in C:\system\apps\, which is mainly used to store the archived files of the games. After deleting games, these folders can also be deleted. Some friends like to listen to MP3 on their mobile phones or want to watch movies. When they send them to their mobile phones, a warning of "insufficient memory" will pop up. In fact, just go to the main menu-
