    So why do you think the bluetooth firmware is present in fw_all.bin for 37xx? Is it only because you've found BRF6350 string and the firmware version string? Or do you have some other information sources?
    Some firmwares are indeed present in fw_all.bin like the PMIC firmware, but I haven't found a bluetooth firmware in fw_all.bin, except the fact that during bluetooth initialization fw_all.bin sends ~11kbytes to bluetooth module, which seems to be too small for a bluetooth firmware.

    UPD:
    Also it seems that 0xF5 is a virtual region with contents stored in 0:/.System/RemoteSW/remotesw.gcd
    On 14xxTV bluetooth firmware is read from 006B097701.gcd
    On 37xx I don't see any firmware updating code yet.

    For BTM is only folder in .System,but in remotesw is no GCD for bluetooth.Also 3490 dont have nothing for bluetooth on device.
    Maybe FW unpack bluetooth FW in folder BTM?
    I found on 3490 in 006-D1283-00.bin is writen supported phone and function (you can also open with notepad):

    [SE S700i]
    PhoneBook=at115200
    SMS=at115200
    Phonebookfun=1
    smsfun=1


    [SE S710a]
    PhoneBook=at115200
    SMS=at115200
    Phonebookfun=1
    smsfun=1
    Becouse i dont know xor i dont know what is in 006-D1283-01.bin

    Here is BTM folder from 3490:

    I've found something intereseting [Only registered and activated users can see links. ].
    brf6350.bin is very similar to those ~11kbytes being sent to bluetooth module by fw_all.bin.
    And it's called a bluetooth firmware there. So I guess Giomen is right.
    The strange thing is that brf6350.bin is not a monolithic peace of code, it's a sequence of packets delimited with 0x01 byte. So the data is formatted in the following way:
    0x01 <2 bytes for message code> <1 byte for message data length> <message data> 0x01 ... repeat until end of file.
    The same thing is valid for data inside fw_all.bin, it is treated as a sequence of packets by fw_all.bin

    There are also never bluetooth firmware versions [Only registered and activated users can see links. ], but it's also said that each firmware requires it's own intialization script. So, I guess, it's not easy to replace bluetooth firmware inside fw_all.bin.

    006-D1283-01.bin doesn't look like an encrypted file, because there are some non-random byte sequences like E1 E0 E3 E2 E5 E4 E7 E6 F9 F8 FB FA.
    And, assuming it's not encrypred, it's not a firmware. Can you check if it's created by fw_all.bin? Maybe it's some kind of a diagnostic log.

    You were right, it's an encrypted file. Here is the decrypted version and the decryption tool: [Only registered and activated users can see links. ]
    The encryption algorithm was so stupid that it produced non-random byte sequences like E1 E0 E3 E2 E5 E4 E7 E6 F9 F8 FB FA.
    And it's not a firmware definitely.

    What is it then? Supported phones and their features? BTW the JPN FW of 3770 allows adding an audio device through the Bluetooth (A2DP?):
    [Only registered and activated users can see links. ]

    Can you extract from it the 11bytes dedicated for the BT?

    I don't know what's 006-D1283-01.bin. Also bluetooth firmwares are identical in both firmwares.
