So I've got an amazon fire tablet 10 and my younger brother was messing around with the settings and set the screen width to 100dpi as a prank and the phone's screen ended up turning black and he couldn't reverse it. I tried my luck with it but failed terribly while trying, I tried to use the fire toolbox to try factory reset it but that didn't seem to work well.

I then tried using the fire toolbox to try load the bootloader (even though I have little knowledge about it) and that option fell flat as well.

I usually use this tablet to test run projects that I found fascinating online but I can't do that anymore with this new-founded dilemma.

If anyone has experience resetting androids of any sort or more specifically amazon fire tablets, your inputs will be very much appreciated.

Screen resolution is stored in userdata, factory reset will fix it. changed settings does not apply to recovery mode, you can enter by pressing Volume Up + Power buttons.

Note: factory reset from recovery will activate (FRP) factory reset protection. google play account is still required to unlock FRP afterwards
