the process can be described as "complicated". Let's take a look at some preparatory work needed for "burning the number". For example, today's

changes the file system to reconfigure the iPhone4 (making the Verizon version of the iPhone 4 support other carriers).

you need to pay attention to the following prerequisites:

you have escaped from prison and installed the CDMA iPhone 4 SSH client program of OpenSSH

PLIST file editing tool

It is declared that it is definitely not illegal to reconfigure your iPhone, as long as you still keep the MEID of the original operator in the CDMA iPhone.

(MEID is the only 56-bit mobile terminal identification number in the world. The identification number will be burned into the terminal and cannot be modified. It can be used to identify and track mobile devices.

because the ESN segment is a limited resource, it is basically exhausted, so the 56-bit MEID segment is formulated. MEID is mainly allocated to CDMA mobile phones)

This course absolutely does not allow any form of modification, replacement or rewriting of ESN/MEID information of any phone.

note: because some popular CDMA models abroad write their mobile phone numbers into them, they can be used directly without putting in a SIM card or UIM card, but this is not the case in China. Therefore,

users who buy parallel models can only use their mobile phones normally through the number burning service. However, five numbers, IMSI, ESN, AKEY, AA and AN, have become obstacles for users. These five numbers are also referred to as "5 codes" for short. If users want to use the parallel CDMA mobile phone in their hands, they need to know these five numbers to successfully write the phone number into the mobile phone. According to media reports,

Now some business halls and middlemen of China Telecom can provide 5-yard inquiry service. The price of the 5-yard inquiry service provided by this merchant is generally around several hundred yuan.

Windows system:

1. Download WINSCP, PUTTY or Tunnelier software (PUTTY is a set of free SSH/Telnet programs, which can be connected to a platform that supports SSH Telnet online,

and can automatically. Tunnelier, an SSH client software, includes a TCP/IP channel providing manual rules and an integrated SOCKS and HTTP protocol for

dynamic sending. The software has automatic reconnection function, a graphics SFTP file transfer client, a console mode SFTP client,

an FTP-to-SFTP protocol bridge, simple click remote desktop sending support for graphics server access, and Vt1, Xterm and BV $ TERM terminal console support. Tunnelier supports all SSH servers.

2. In order to connect via SSH, you must first set up the WiFi connection. Turn on the phone's WiFi function, and connect to your wireless network by setting up WiFi. 3. After the connection is successful, you will see the WiFi icon in the status bar at the top of the iPhone, and view the details about the connection. Here, please write down your IP address, which should be 192.168.*.* 4. Install the SSH client and start it, and fill in the IP address on the iPhone: user name: root password: alpine

5. Press the "Login" button, and you will see that one or two new windows will open

6. This shows that you have logged in and connected with Tunnelier or other SSH programs now. (Take Tunnelier as an example)

Apple computer:

Please follow the above steps. Use the Cyberduck software

------------------------------. --------------------

1. Open the/system/library/carrier bundles/iPhone/of the iPhone using the explorer window of Tunnelier. The file shelf structure is:

carrier.plisteri.plistinfo.plist

other files, etc.

2. Make a backup of the above files on your hard disk, so that it can be used for recovery when the phone goes wrong in the future.

3. Here we need to manually update the original PRL of iPhone to a new operator PRL(PRL: preferred roaming list), rename the obtained PRL of China District (which needs to be provided by the operator) to 31VZW.prl, and put it in the path of/system/library/carrier bundles/iPhone/zeppelin _ us.bundle., Overwrite the file with the same name at the same time. 4. use plist file editing software to open the carrier.plist file in the hard disk backup file

5. look for the "PrlPushFlag" field in this file and change the following coding from "false" to "True" (as shown below)

6. save the modified carrier.plist file. Then upload the file to the folder/system/library/carrier bundles/iphone/zeppelin _ us.bundle to overwrite the original file, and then restart the phone.

-----------. Because PRI needs to be signed, but now we can't bypass this step or replace it with other methods, so we can only modify the information in PRI first. PRI is a carrier containing information about operators, including ERI, EVDO, NAM, OTA features and other miscellaneous information. Here is mainly to solve the problem of baseband.

we still need to use plist software to modify the carrier.plist file. Find the PRI Version field.

original:

<; key> PriVersion< /key> < string> .1.23< /string>

is revised as:

<; key> PriVersion< /key>

< string> .1.24< /string>

find the field shown above, increase the version number by 1 according to the above method, and then restart the phone. After restarting, check whether

is "syslog" (recorded in the system record).

However, the problem is that PRI needs to be signed, that is to say, at present, only the baseband version has been replaced. If it doesn't work, it should be restored to the previous .1.23.

-----------. Dialing program code

--------------------------. Here are some dialing codes for iPhone 4, and some related functions can be realized by inputting them on the mobile phone.

*#55*4357#, showing PRL and PRI versions *#55*74663#, showing the user's current MDN number *#55*25327#, screen test? (flashing) *#55*274#,

It has no effect, but there is a leave button *#55*7828# on the screen, which is the same as 3 *#55*78283#, and the debugging log # # 2539 * # 55 * 342444 # may be displayed. Such as power-on and power-off time

* # 55 * 5667 #, send [5667 = loop] displays loopback call ui enabled = fals, and there are some dialing codes with unknown functions, so I won't list them one by one
