this alone won’t likely work, if not, continue:

if you skip this you will get this error: flashromPartialWrite() so read on carefully

you’ll haft to get into the system and remove the rewrite screw. on the Acer Chromebase 24 if a bit difficult to open the case, but very doable. 3 screws at the bottom and then a couple pry tools should do the trick, unlike most laptops, or other all in ones, this particular model is difficult to get in simply because of the rigidity of the plastic and design. lay it on its face, remove the stand, then the 3 screws at the bottom edge, once those are off, its a matter of prying the back off. once this is done, you will see a whole lot of sheet metal covering all the electronics, remove what you can and you’ll find a motherboard and on this motherboard is the rewrite screw, take it off and boot the machine back up.
