[BitPim-devel] brew serial protocol..

[Simon C]

There is a hack on the vx8100 that requires the user to modify one of the
NVM files.
This cannot be done with BitPim, but a well know program from Qualcomm is
able to do this if you overwrite the file.

I had a quick look at the serial port comms to see what was different
between this program and bitpim and can see that a totally different set of
commands is being used to manipulate the file system. The commands start
with 4B 13 mostly instead of 59.

Modifying bitpim to allow it to write the nvm files is going to take some
time, and I'm not sure if it is worth it seeing how it understands the older
serial protocol anyway.

Does anyone have any documentation available for this protocol?

What's exactly what are you trying to do: making changes to one of those files? What did you try that didn't work?

I assume you meant QPST.

The latest firmware for the 8100 blocks DUN. It can be unblocked by changing
one of the nvm files. You cannot use bitpim, it gives an error when trying
to write the file.

file.

I assume Delete/Restore did not work either. What exception did you get?

No they did not. (in QPST this does not work, you have to overwrite) It gave
