I am currently S-Off and on an Unlocked Bootloader. I have the Harmon Kardon sound mod applied.
I used to have TWRP recovery and last night flashed on a stock recovery to my device.
When I click on the OTA download install my phone reboots to recovery with the Triangle and a Green Line. This progresses to around 30-40% completion and then stops and shows the Red Triangle which means I have to Vol Up + Power to restart.

Mine is 18.104.22.168
CID is: ORANG001
Anyone have any idea where I am going wrong?
