[Q] Can't install JWR66Y OTA, framework problems
When I try it bombs on /system/framework/android.policy.jar and stops.
Now, I have not been using OTAs except maybe when I first unboxed it and let it do its think 6 months ago, because I put TWRP 126.96.36.199 on as soon as I could. I went from JO40D to JDQ39 in a ROM from someone here, then JWR66V from another ROM. These were (mostly) stock ROMs, I just didn't want to wait for OTA.
Well now my system says an update is available. It's only 1.7mb and sitting in /cache. But it won't install. I've tried through recovery (TWRP), letting it do it on its own, and ADB sideloading. all fail same place.
Now, I recently installed Advanced Power Menu for JWR66V. I suspect it may have changed the files. Or, it could be any of the other ROMs along the way, I've saved them and opened them and saw no android.policy.jar in /system/framework, so I assume it's a file that has not changed for many versions.
OR, I'm getting confused, and I'm not certain WHICH JWR66V I have, so maybe didn't save it. I recall having issues with one 4.3 so I tried another - which one I'm on now I'm not sure but I think it's AOSP-4.3-JWR66V-grouper-rooted_Androguide...and now that I look, it does have a full /system/framework. Is the OTA choking on that?
I tried downloading a factory image and discovered after opening them up they are just .img files and I'm not sure how I can get individual files out..or if I even should, or which version, lest I render my Nexus 7 unbootable.
I just want to get my system back to a functional state (without losing my data or files or setup or recovyer), from which it can update to JWR66Y.
Or should I just wait for someone to roll up a full ROM of JWR66Y since I've strayed so far from the OTA path?
