I recently installed LightningFastRom 17.1, a ROM based off LineageOS 17.1, for my Galaxy Tab E 9.6 (SM-T560NU-gtelwifiue). For GApps, I used OpenGApps (arm, 10.0, micro). I modified the .zip file using this video. When I first booted it, it worked perfectly, then I flashed SuperSU. I waited an entire day and it still didn't boot. Does anyone know how to get back to recovery while on the boot screen, I decided to flash a new ROM.
