I cant find an updater tool?!
I am used to put firmware and a boot system on a USB Flash memory, or CD, and let the computer boot on it.
That method is much more reliable than from a running OS, and is also OS independent.
I have seen it also for an elder acer laptop.
But can not find for this model acer Aspire 7, Model A717-71G.
An updated firmware itself i find athttps://www.acer.com/ac/en/US/content/support-product/7297?b=1&pn=NX.GTVED.005
and acer is still working on Spectre & Meltdown fix so there will probably come yet another soonhttps://us.answers.acer.com/app/answers/detail/a_id/53104
But how to get it flashed?
PS: we upgraded the OS to Linux /DS
