A First Public Offering of Purism Stock on StartEngine. Minimum $500.
With this (E)mbedded (C)ontroler update, your Librem 14 will have better temperature management; fans will gradually ramp up earlier. You’ll also get improved keyboard mapping and better switching between battery and external power supplies.
You’ll need your Librem 14 charging and a USB drive you can completely erase.
Live USB setup:
Download the ISO called Librem_14_EC_Update_stable from here. You’ll need to write this to a USB drive.
Those that prefer command line can use this:
sudo dd if=~/Downloads/Librem_14_EC_Update.iso of=/dev/sd<changes per device> bs=4M status=progress;sync
Gnome-MultiWriter is a good option if you prefer using a modern interface.
MultiWriter writes a selected ISO to all listed devices. I like to run it without a USB drive attached to verify it’s not going to overwrite one of my storage devices.
Once you plug in your USB to overwrite, you should see it pop up in the interface. Make sure that is the only listed device.
Select the freshly downloaded ISO with the open folder icon.
In the menu, disable wipe. This save a lot of time, but leaves some data on the drive that could be recorded with tools like PhotoRec
If you are sure all the drives listed are okay to overwrite, select “Sart Copying” and enter your password.
Once this command completes, you now have a bootable USB with the needed EC flashing tools.
If you are running PureBoot you need to be on version 18.0 or Higher. To upgrade to version 18.1:
Booting and Upgrading
Reboot and select the new USB to boot up. If you’re on PureBoot select: Options -> Boot Options -> USB boot -> option ending with ISOIMAGE
Once fully booted, simply run:
Once the script completes, you can reboot to the same USB and run this validation command:
sudo purism_ectool info
