Booting Up to Colored Lines on Black Screen (SM-T580) (Oreo 8.1)

[infernape099]

I tried to use Odin to flash my tablet, but I think I screwed up because the device is in Oreo and I tried using TWRP/"No-verity-opt-encrypt-5.1"/SuperSU. I thought it was as simple as that, and it passed. But when I got passed the "Galaxy Tab A" when I boot up, I get two columns of blue down the middle, then it immediately it turns to red lines. I can literally do everything, but the screen doesn't show anything but those lines. The buttons at the bottom work and I can go into download mode. I also tried to flash the device back to Oreo, same thing. I tried to use SmartSwitch but "this device does not support initializing". In Odin mode, it says: "PRODUCT NAME: SM-T580, CURRENT BINARY: Custom, SYSTEM STATUS: Custom, FRP LOCK: OFF, WARRANTY VOID: 1 (0x030c), RP SWREV: B:4 K:1 S:2"

Of course you backed up your original system before you tried to put in the new one.
So just upload the original and you should be good to go!

I didn't but even if I did, it wouldn't have changed anything because I already tried to flash the device with the factory software.
