> Lenovo are currently investigating what went wrong
I've just heard back from them. The bricking should only only occur on these selected models when you upgrade from a very old firmware version to a very new firmware version. This is because the old (as in the version you're upgrading from) firmware had a bug that meant the screen was not initialized correctly and the update progress bar was not being shown. The beeps actually mean "flashing, don't turn off" rather than "system error".
> After about one minute I manually switched off the system via a 5 second press on the power button
This is when the firmware was actually being flashed -- but of course you didn't know that :(
Lenovo are preparing a new update that checks the previous firmware version before being scheduled. This should be on the LVFS in the next few hours.
They also shared some guidance about how to recover a bricked machines:
* Remove all power supplies, which includes the AC adapter, the main battery, *and* the coin battery.
* Press and hold the power button for 30s.
* Attach all of power supplies and press the power button to power on the computer.
Depending on when the firmware update was interrupted this may or may not recover the laptop.
