No brightness control, on superdim. Possibly rooted before.

I bought a Note 8 from a pawn shop for $15 because the screen "wouldn't come on". When I got home I noticed it was indeed on, just on superdim. It has full backlight working, just no control over the brightness. The slider moves to any percentage, but does nothing. It can be adjusted to be Dimmer using app store programs (though I suspect it is just filters not actual brightness control on these apps).

I've seen things like this with rooted devices being factory reset on Kindle HD and thought it may have had a custom ROM before and the pawnshop reset it to sell it and this happened. Makes sense since the tablet was working before they reset it to sell.

How do I go about getting this set back on a factory flash? After that how about a one click option for a custom ROM after it's working properly?

Side note, if the backlight is indeed working and on superdim (this is confirmed) could it be a sensor going bad instead?

How do I get a wifi only model into service mode to do a sensor test?

THIS MODEL IS: GT-N5110 WIFI ONLY.

Thanks

Hi, I have a Note 8 as well. I got mine from a pawn shop for $20, because the screen was super dim from the last owner spilling makeup or something on it. The guys at the pawn shop didn't know what was wrong with it and sold it to me for $20. I took it back home and had a closer look at it... It had a screen protector on it, I peeled off the screen protector and the screen was perfectly fine and there was absolutely zero ink/makeup whatever on the device at all. Ever since I did that, there was no more brightness/display issues. I've since replaced the screen protector due to one saving the devices ass lol. Check and see if yours has a screen protector you can peel off.

Brightness Widget - Backlight!

Just use it's default settings while setting it up, then just tap on the bulb on the homescreen to make it adjust the brightness. If it doesn't adjust the brightness for you, then something in your device is definitely damaged (or modified due to a faulty rom). Post back!
