[AC Question]

I decided to do a factory reset on my Acer A1-830 tablet. After about 4+ hours of being at the startup screen where Acer logo is shown, it just turn black. After some time, a new screen pop up, it has a logo with a circle with a line going up connected to a triangle. Then 2 curve line stick out which connect to a square and a circle. Underneath, is a rectangular white box which occasionally turn red.. I tried everything I could think of but it either stay at that screen or turn off. I think it only show that screen if the USB is plugged in. Please help me.

Can you post a picture of what it shows on your screen?

New Update: I plugged th USB into a portable charger and for some reason, now it's back to the screen with the Acer logo. Still stuck.

I included the photo as an attachment for you. In the future, use the attachment feature rather than linking. Regarding your problem, it looks to be in a download mode or something similar. Prior to this issue, did you only factory reset via the system settings? Or did you do something else before the reset (i.e. attempt to flash custom software)?

Yes, all I did was factory reset it through settings. It was rooted, however, if it means anything.

Also, now it's stuck at the boot up screen with Acer logo. That's only when it's plugged in via USB. If it's not plugged in, it turns off and won't turn on unless plugged back in.

Well, sometimes it's stuck at white USB screen while others stuck at Acer logo boot up screen. Seems like it needs to be plugged into something to even turn on and what screen pop up depends on what I'm plugging it into

Search for the exact firmware for your device and flash it. From your descriptions it seems like your battery is dead

How do I flash it? And I don't think the battery is dead because it worked fine before I did a factory reset. But sometime could have happened when I factory reset it.
