No issue here. I thought devs patched their kernels with dr87's auto panel detection?
i have a jdi panel for my d800 ... i did this 2 days ago and gave me the white lines until i flashed a jdi kk kernel.. used latest autorec so im not sure...
okay i may be making progress here.. after digging around i managed to get it to the twrp menu i am using v18.104.22.168
i fixed it, just flashed recovery with lg flash tool :)
