It's my girlfriend's tablet, my son had it when screen blacked

Ok long story short I let my 9 year old use my girlfriend's tablet ( that she had just gotten for Christmas). We swears he never dropped it and I believe him. He said he was watching YouTube and the screen just went black. I've played with it off and on. I know a few things about flashing, rooting, and roming. I got the battery icon to flash on 1 time and never again. Any help would get my son and I out of the doghouse

Check for the KNOX flag and you’ll know if your son messed with it in ways that may be hard to recover from. You can check for the 0x1 flag (tampered) by going into OS Download mode by using these instructions. If your son DID root the tablet, you’re in the dog house if she uses it for work and has to have the 0x0 flag - it erases the encryption key used by the KNOX workspace and disables the feature permanently as it’s an eFuse. I’ve heard it can be reset using JTAG, but most people on this site would make things worse if they did try and reset the eFuse over JTAG. You can’t use Triangle Away anymore - it hasn’t worked since 4.3 since it’s embedded into the operating system from day one.

The other indicator (easier for end users) is if you get the custom triangle at boot - this WILL get you into trouble since she will see it as it comes up at boot persistently.

If it’s just black, you need to do additional troubleshooting. If it’s a cracked screen, you can find a Google FRP donor to get the part from and fix the tablet that way.
