Laptop 13 7040, Crash during firmware update from Ubuntu 26 - laptop won't boot

Which Linux distro are you using? Ubuntu

Which release version? 26.04 - LTS
(if rolling release without a release version, skip this question)

(If rolling release, last date updated?)

Which kernel are you using? Can’t check - won’t boot

Which BIOS version are you using? Trying to update from JFP30.03.18 to JFP30.03.20

Which Framework Laptop 13 model are you using? I have a Framework Laptop 13 (AMD Ryzen 7040 series, built July 2025).

I was updating the BIOS from JFP30.03.18 to JFP30.03.20 using fwupdmgr on Ubuntu 26.04. After restarting, it entered the update screen but became stuck. I have performed multiple mainboard battery disconnects (4+ times, up to 15–30 minutes each) and power resets. Current symptoms:

  • Fan runs intermittently
  • Side LED cycles between blinking red, steady green, and blinking red/green
  • No video output on internal display or external HDMI monitor
  • Power button and charger respond (LED changes)

The laptop is otherwise responsive to resets but will not boot to a visible screen or allow reliable USB boot.I have tried the EFI USB updater (correctly structured) with blind F12 spamming, but no success.
