I bought a Camera (Lumix GM5), but I can't change the language of it.The easy way is to send it back to Amazon, but I want to try to change itby modifying the firmware before.So, I used binwalk to analyze the firmware: root@ec5b1dd5bce3:~# binwalk GM5__V11.bin DECIMAL       HEXADECIMAL     DESCRIPTION6789427       0x679933        MySQL MISAM compressed data file Version 930718920      0x1D4BBC8       MySQL ISAM index file Version 131869478      0x1E64A26       ZBOOT firmware header, header size: 32 bytes, load address: 0x29F4F830, start address: 0x9692295D, checksum: 0x11837327, version: 0xB1437316, image size: 1837825596 bytesI see that there is misam compressed data.Maybe I can change the language here, maybe not.So to exract it with binwalk again I did :[root@ec5b1dd5bce3:~/_GM5__V11.bin.extracted# binwalk -D '.sql:myd:myisamchk' GM5__V11.bin which give me two files:binwalk 679933.myd DECIMAL       HEXADECIMAL     DESCRIPTION0             0x0             MySQL MISAM compressed data file Version 923929493      0x16D2295       MySQL ISAM index file Version 125080051      0x17EB0F3       ZBOOT firmware header, header size: 32 bytes, load address: 0x29F4F830, start address: 0x9692295D, checksum: 0x11837327, version: 0xB1437316, image size: 1837825596 bytesAnd :[root@ec5b1dd5bce3:~/_GM5__V11.bin.extracted# binwalk 1D4BBC8.myd DECIMAL       HEXADECIMAL     DESCRIPTION0             0x0             MySQL ISAM index file Version 11150558       0x118E5E        ZBOOT firmware header, header size: 32 bytes, load address: 0x29F4F830, start address: 0x9692295D, checksum: 0x11837327, version: 0xB1437316, image size: 1837825596 bytesBut now when I try to use myisamchk on my new files it failed :root@ec5b1dd5bce3:~/_GM5__V11.bin.extracted# myisamchk 679933.myd myisamchk: error: '679933.myd' is not a MyISAM-tableI guess it's because I still have the ZBOOT firmware header in my .myd files.So I was wondering, what is the proper way to extract only specific signatures ?Thanks.
