Sorry for not coming back sooner.

First, I do not have a Windows PC, I use a MacBook Pro running OSX v10.11 64 bits with Parallels v11 and a Windows 7 32 bits in a VM.
I have spent the last 2 hours trying unsuccessfully to update the unit and now I have fried my unit. 8-(
I was working on a antistatic mat with a grounded bracelet at all time

This is what I did ...
a) I have downloaded and installed the mspdebug-0.23-win32-signed.zip software
b) I have downloaded your firmwares
c) I have tried to use the command -> mspdebug rf2500 "prog np41.hex" but the software is not seeing the MSP430 through the USB port
d) mspdebug --usb-list return nothing
e) I then registered myself on TI website and downloaded the dev kit (msp430.dll_developer_package_rev_3.07.000.012.zip)
f) I then installed the VCP drivers and Windows now sees the MSP430 unit as COM7
g) mspdebug --usb-list still return nothing (as expected)
h) mspdebug rf2500 "prog np41.hex" still not working (as expected)
i) I then downloaded and installed the "Realterm_2.0.0.70_Signed_Wrapper_setup.exe" software
j) started RealTerm and he sees the COM7 with 9600,n,8,1
k) I have tried to go into the bootloader as instructed and tried multiple things (no battery)
-> physically disconnect/reconnect the USB cable with user key pressed (several times, never worked)
-> virtually disconnect/reconnect the USB cable with user key pressed (several times, never worked)
-> physically disconnect/reconnect the 6 pins cable from the calculator (once, this is what killed the unit)
L) Then I tried to insert a new battery but there is no response anymore

That was short!!

Best regards,

Sylvain

Do you have an NP41 or an NP41S?

To me it looks like you downloaded the firmware for the NP41 and used the flash command for the NP41S.
