Moto X(2013) back light problem- Failed to open back light: no such file or directory



So my Moto X (2013) got switched off at 1% battery. I charged it and turned it on again. Now I can't unlock it from the active display lock screen. Whenever I try to unlock it nothing happens except for a black blank screen. The phone took a while to start and it said "Android is upgrading..." and went through optimizing of apps. Finally I get to the lock screen, I can see the messages, missed calls from the lock screen, but I can't unlock my phone and go to the actual messages or call list. After repeated attempts I went to the recovery and wiped cache partition. Still no luck. Then I go to see the recovery logs and I see this..
Moto X
"Failed to open back light: no such file or directory"

Is there any way I can correct this except by factory resetting? I have lots of data stored on my phone and I really need them. I don't want to factory reset it. Or is there any way I can take backup of everything and then go about resetting it? Or can I apply an update so my phone won't lose data?

My phone runs Lolipop 5.0 and I also have the 5.1 update zip file with me. Phone is not rooted or unlocked. Please help me fix this
