Unable to update Firmware on nRf9160

octvargas

I'm having trouble connecting with LTE, so I decided to update the FW and see if that helps, but I am having trouble even getting started with this.

This is on Windows Home 10

I downloaded the zip file and extracted it

Went through the README.rst

Extracted the second zip

and ran the command on the command prompt to get this error

I'm a bit stuck and any help would be appreciated

    Hi Octvargas,

    The v1.0.0 of the modem firmware was just released as well as NCS v1.0.0!

    • Please get NCS v1.0.0 with:

    cd ncs/nrf
git checkout master
git pull
git checkout v1.0.0
west update

    • There is a new way to do modem DFU with version v1.0.0 of the mfw:

    - Update to the latest 'nrfjprog'. (download link)

    - Download mfw v1.0.0

    - Update to nRF Connect for Desktop to v3.0.0

    - Make sure you have the latest version of the "Programmer" app:

    - Open the "Programmer" app 

    - Select device

    - Select "Update Modem"

    - Find the .zip folder 'mfw_nrf9160_1.0.0.zip' and select it:

    - Hit the "Write" button

    Now the Modem DFU procedure should start and you should get the newest modem firmware.

    You can confirm this by running the at_client sample in combination with "LTE Link Monitor" and sending the AT command: 

    AT+CGMR

    Note that there is also released a new SES IDE version (v4.18) with several updates.

    Please find the newest version from the download link in the "Getting Started Assistant" app:

    Best Regards,

    Martin L.

    Hi 

    I have run into some problems while updating to the new firmware. When I try to get NCS v.1.0.0 I get the following output:

    fatal: unable to access 'github.com/.../': SSL certificate problem: self signed certificate in certificate chain

    How can I fix this?

    Kind regards

    Samuel
