Issue with Flashing UEFI Full ROM on Acer Chromebook 11 C730-C8ZD - Screen Lights Up, But No Display

How do i solve this problem

Did you use a SuzyQable to disable WP?

No. I removed the wp srew from the motherboard

I dont really know anything about the wp screw but I heard using a SuzyQable is more safer

Wait when was your Chromebook made

Okay mate thanks
