I recently got a Librem 15v4 and a Librem Key (Made in USA) and I am trying to follow the documentation to install PureBoot. After running coreboot_util.sh and choosing “Update firmware using precompiled image” and the appropriate options I get a message at the end that the precompiled image has the wrong hash. See output below.
Which Librem device do you have? # Broadwell/5th-Gen 1 - Librem 13 v1 2 - Librem 15 v2 # Skylake/6th-Gen 3 - Librem 13 v2 4 - Librem 13 v3 5 - Librem 15 v3 # Kabylake/7th-Gen 6 - Librem 13 v4 7 - Librem 15 v4 My spidey sense tells me it's a Librem 15 v4 Enter your choice (default 7): 7 Which firmware type would you like to flash? 1 - Standard (coreboot/SeaBIOS) [v4.9-Purism-1] 2 - PureBoot (coreboot/Heads) [v4.8.1-PureBoot-beta8] Enter your choice: 2 Note: PureBoot firmware is currently in beta, and requires a Librem Key as well as a dedicated, unencypted boot partition. Are you sure you want to switch to the PureBoot firmware (y/N) ? y Set the device serial number: 1 - Extracted from your local system (xxxxxxxxxxxx-xxxxxxxx) 2 - Enter serial number manually 3 - Do not set a serial number Enter your choice (default: 1): 1 Downloading precompiled coreboot image...--2019-07-17 23:26:01-- https://source.puri.sm/coreboot/releases/raw/47217fd9a4d567fb7b319c8f614c433c9ebe267f/librem_15v4/coreboot-heads-l15v4.rom.gz Resolving source.puri.sm (source.puri.sm)... 18.104.22.168 Connecting to source.puri.sm (source.puri.sm)|22.214.171.124|:443... connected.
