Hello,

Recently I was messing around in TWRP, trying to reflash a rom in an attempt to correct the touch screen not responding within a horizontal line about 25% the thickness of the phone, just above the middle of the screen. Thanks to the faulty touchscreen, I managed to get into screen settings and click something that instantly turned off the screen backlight. At the time, the screen appeared completely black. Upon closer inspection under light, I saw that the screen was on, just not backlit.

The phone will boot as normal and I can see the screen, barely, even if I seriously strain my eyes under direct light; for the most part I can only see white text like the clock on the lockscreen or the battery meter in TWRP.

With some repeated effort, I can get the phone into recovery/bootloader/download mode. I'd like to know where I can go from here to resolve the problem. I'm experienced with flashing and I'm decent with adb and fastboot, but I wasn't able to get fastboot to detect the phone even with the drivers installed.
Provided I can get the phone to show up on my PC, what should I flash to try and repair it? I have a D803 Rogers variant.

Note: I already tried to warranty it (risky with it rooted, I know), but they claimed there was water damage. The water strip may have been tripped by some steam from the shower, but I certainly have not submerged my phone, and the problem did not arise under moisture conditions.

Thanks for your help!
