Stuck in recovery mode, power button broken

My Samsung galaxy j5 (2015) is stuck in recovery mode, If I pull and put back the battery it boots in recovery, if I let the battery run out and then charge again it still boots automatically in recovery mode. No custom recovery, no custom rom, it is rooted, I can't remember if usb debugging was on. On the bottom it says: No Support SINGLE-SKU Supported API: 3 dm-verity verification failed... One day I accidentally restarted it on recovery because the power button is broken and I use an app to turn it off, it has remained like this since, it was fine before. I tried using adb but I don't know why my pc can't see the device. I really don't want to lose my data. Can someone help me? (Btw, why when I press a button the selected option becomes green?)
