File update system and boot management system of mobile communication terminal, method of updating file in mobile communication terminal, and method of booting mobile communication terminal

1. A mobile communication terminal, comprising:

an embedded file system (EFS) area comprising a header of a file corresponding to a first version; and

a processor,

wherein, if the header of the file corresponding to the first version and stored in the embedded file system (EFS) area is damaged, the processor reads a header of a same file corresponding to a version preceding the first version, and registers the read header in an EFS area table for boot management.

2. The mobile communication terminal of claim 1 , comprising:

a header reader to read information of the file registered in the EFS area table,

wherein the processor, if a file name is damaged in the damaged header of the file, analyzes header information of files stored in the EFS area to retrieve file names of files having identification (ID) corresponding to ID of the file having the damaged header and to identify the header of the file corresponding to the version preceding the first version.

3. The mobile communication terminal of claim 1 , wherein the processor reboots and initializes the EFS area table after registering the read header.

4. The mobile communication terminal of claim 1 , wherein, during an initialization process of the EFS area table, the processor determines whether the header of the file stored in the EFS area is damaged.

5. A method of booting a mobile communication terminal, the method comprising:

reading a header of a file registered in an embedded file system (EFS) area table;

if a file name is damaged in the header of the file registered in the EFS area table, analyzing header information of files stored in an EFS area, retrieving file names of files having the same identification (ID) as the damaged file, and recording header information of a file of a newest version among the files having the same ID in the EFS area table to recover the EFS area table; and

initializing the EFS area table using the recovered EFS area table.

6. A method of booting a mobile communication terminal, the method comprising:

reading header information of a first file registered in an embedded file system (EFS) area table;

determining whether a header of the first file is damaged;

in response to a determination that the header of the first file is damaged, retrieving header information of a second file, the second file being a version of the first file different from the damaged version of the first file, the first file and the second file having a same file identification (ID); and

registering the retrieved header information of the second file into the EFS area table.

7. The method of claim 6 , wherein a Boot Information Block (BIB) comprises the embedded file system (EFS) area table.

8. The method of claim 6 , wherein the reading of the header information of the first file from the EFS area table is performed during a boot process.

9. The method of claim 6 , further comprising:

determining whether to search for one or more files having the file identification if the header of the first file is damaged or an error occurs with respect to the first file.

10. The method of claim 6 , further comprising:

rebooting the mobile communication terminal if the retrieved header information of the second file is registered into the EFS area table.

11. A mobile communication terminal, comprising:

a memory comprising an embedded file system (EFS) area table; and

a processor to read header information of a first file registered in the EFS area table, and to determine whether a header of the first file is damaged,

wherein, in response to a determination that the header of the first file is damaged, the processor is configured to retrieve header information of a second file corresponding to a version of the first file different from the damaged version of the first file, the first file and the second file having a same file identification (ID), and to register the retrieved header information of the second file into the EFS area table.

12. The mobile communication terminal of claim 11 , wherein a Boot information Block (BIB) of the memory comprises the embedded file system (EFS) area table.

13. The mobile communication terminal of claim 11 , wherein the header information of the first file is read from the EFS area table during a boot process.

14. The mobile communication terminal of claim 11 , wherein the processor is configured to determine whether to search for one or more files having the file identification if the header of the first file is damaged or an error occurs with respect to the first file.

15. The mobile communication terminal of claim 11 , wherein the processor is configured to reboot the mobile communication terminal if the retrieved header information of the second file is registered into the EFS area table.
