Hey folks, I recently rooted my LG G3 D850 earlier this week on Lollipop stock. When I go to the Flashify app, recovery image, choose a file, twrp.2.8.0_d850-signed.img, and try to flash it from there, it says error on the screen, and my led light keeps flashing in different colors. Thankfully, I can pull the battery out, and turn it back on to normal. Any help? Thank you.
