Hoping someone here can help. I have a rooted Nexus 7 on 4.4.1 (KOT49H), and I figured it's about time to update it, but every time I do I'm getting an error. Do I need to reset it to factory settings to update it? I have a bunch of the incremental updates downloaded (in the !Ready to flash" folder, and on my PC at home), making sure that each one follows on from the other, that I tried to flash and sideload over with the Nexus Root Toolkit, but I'm getting errors regardless of which method I try.
I don't really know what I'm doing with this stuff, I know a little and have been following guides, but it's all fairly new to me so if the easiest option for me is to do a wipe and then try again then I'll do it, but I'd prefer to keep everything that's on there if possible. What should I do?
