I'm on a rooted Nexus 7 2013 wifi only with twrp recovery installed. I'm currently running stock android 4.3 and wish to update to 4.4.2. I had originally held off updating but now want to do so. Here's what happened.
1. I first went to Settings /about phone /System update and tried to update. That failed repeatedly even though I have unmodified stock rom. (now even download fails though earlier it has downloaded successfully and the file is somewhere on the tablet).
2. So I next went to
http://forum.xda-developers.com/show....php?t=2380113
And downloaded the ota update zip file (JSS15R to kot49h). Then went to my Twrp 2.6.3.0 recovery screen and tried flashing the zip file from there. It failed. I didn't wipe anything first because I didn't want to lose my data.
So I'm stuck. Can I update without losing my data?
Thanks
Jeff
