Actually, I take that back. It seems from this conversation that you corrupted your system partition.
Actually, no sheychis. Over there, we had a useless recovery - it did not have rw permission over the system partition. Over here we are discussing a perfectly healthy recovery and a corrupted system. Most likely android boot sends you to recovery because it fails to boot into system, it detects something wrong and wants you to recover the system partition. I will echo the advice you received in that conversation: Reflash the system partition.
And, Rabbosai: The big mussar haschil here is… ALWAYS MAKE A BACKUP BEFORE YOU MESS WITH THE SYSTEM. “Because afterwards is too late.” ( - Uncle Moishy)
