Hi,
I'm having a Nexus 4, bootloader unlocked, CWM Recovery, stock 4.2.2 ROM and moles' color calibration kernel. (stock except color calibration for awesome screen)
What I'd like to know is whether there is a way to update my device to 4.3 (and moles' color calibration kernel) without losing user-data since I find it a major pain to get my settings and stuff back together as i have it now.
I wanted to update to 4.3 by booting to recovery and install 4.3 zip without factory reset (someone on another forum said it would work if user data is compatible with both roms, i.e. when one the update of the other) and after that I would flash the kernel, which is also stock except for said color calibration. So i thought I wouldnt have to lose data as well. I downloaded the Factory image JWR66V from Google which is a tgz file, which let me wonder in the first place. After I extracted the files in it, there was a zip. I tried installing the zip but CWM aborted the installation, right after it began. I don't know if it was a problem with the zip, because CWM couldn't see the .tgz at all, so i tried playing around and found a .zip in it.
Can someone with more flashing experience tell me, if this concept is even feasible? - Can it be done in a better way? If not, how do i get it right?
tl;dr:
- unlocked/rooted 4.2.2 nexus 4
- want to update to 4.3 without data loss
- can't figure out which image to install via CWM
- need advice on how to do it right, or how to restore my user data after update (like custom dictionaries and so on)
Also sorry for my user name, I have no intention of trolling, I just created this account for research and thought I wouldn't post anyway. And I'm not very creative with user names
I appreciate any help. Best ones will be rewarded with massive amounts of internets.
