I've working on the vm4050, it seems very different than other phones. 

The filesystem contains almost nothing, there are no images, audio,
phonebook, sms or anything else that you would expect to see there.

There are hidden directories in the root (C, D, H so far). These do not
contain any useful data for bitpim, some seem to be used by the browser as
cache. A filesystem is visible within these directories once you know they
are there.

 

The phonebook can be recovered (and set) by sending a sequence of commands
and then reading a file from a directory called SWAP inside one of these
hidden directories..

It goes something like

 

27 .. .. (set some parameter)

F1 00

:loop (300 times)

F1 02 03 .. .. [Phonebook index]

Read file D/APL/SWAP/DIAG_APSWP_MEMORY

F1 01

 

Each time the F1 02 03 command is sent the file contains a different
phonebook entry.

This file is not visible in the file system

It appears that the phonebook and probably much of the other data is stored
outside of the filesystem and that there is a set of commands to map this
data into the filesystem for reading/writing.

 

Has anyone come across anything like this with other phones?
