I am a noob.
In a nutshell, I poked at things I shouldn't have after rooting/encrypting my galaxy note 8" tablet (GT-N5110) and now it continuously loops through the boot up screen. It gives me just enough time to see the "enter passcode to decrypt" screen after the samsung logo, then it re-boots.
I have clockworkmod installed, but I still can't factory reset since I can't unlock the encryption.
edit: This is a tablet, so no battery removal. I hadn't flashed any custom roms (except adding clockworkmod recovery), only rooted and encrypted the device. I accidentally erased the wrong thing when messing with a debloater app, which is why I am now stuck in a bootloop on an encrypted device. No fastboot option, only clockworkmod--which can't help because encryption.
