So I'm a noob at rooting and such. I made an .ab backup of my Nexus 7 before unloving and rooting. The .ab file was around 14 GB large, probably due to my shared storage being included. After unlocking and rooting, I went to restore my device. While restoring, it went through all of my apps until it stayed on one for hours.
I let it restore over night for 6 hours and it still wasn't done. I unplugged it to find some media had been transferred. Currently, I'm missing ~20%of my media.
What should I do?
