Update SPRM

[mave1993]

Hey mates,
any one idea to update an sprm ( 8M5T-19G488-BM ), its an modul with usb, but this is not for playback, BT audiostreaming is not avaible at this device!

I tryed to update it, i changed update files from sound and connect modul to softwarenumber 8M5T-14C350-BV, now the modul will accept the update, its load and load, nothing do, SPRM hangs in update state! after battery reset it worked well, but on old software...

Why they have an USB Port when no update is avaible? Is there way to change firmware on the modul ( with UCDS? ) i dont find bootloader, i think its not avaible.

Any one idea? I founded in FOCUS2 -> VRM one function.. but i think its not to change modul software, only configuration in focus or? if not please correct me :=)

USBport is only on plastic box, not on motherboard in BTmodule

BTmodule with USB: XXXX-19C112-XX (X is alphanumeric)
BTmodule with USB and BTstreaming: XXXX-19C112-XP or XR or higher
