[Q] Reflash stock 4.3 without losing data
my GNex (GSM version) is running very, very slow at the moment. I already tried cleaning the cache and using LagFix, but as fstrim is already included in 4.3, that shouldn't be a problem.
I'm running stock 4.3, rooted but no tweaks or anything applied, root is only for Titanium Backup. My recovery is ClockworkMod 184.108.40.206 non-touch.
So what I'm trying to do is to reflash the stock image as provided by Google, without loosing data, and I'm not sure which steps I should take and before I lose anything I wanted to check back with you if I miss anything.
So, here is how I would do it:
1: Unlock bootloader. It has been unlocked to root the phone, but is locked with the BootUnlocker app. (We don't wanna lose the unlocked bootloader, right?)
2: Nandroid backup. Can't hurt, I guess. Should not really be needed, but better safe than sorry.
3: Run a full Titanium Backup. Store it somewhere safe (not on the phone.)
4: Backup all the data from the device. Problem here is, Windows Explorer crashes if there are many files it should copy, so has anybody a idea how to overcome this?
5: Download factory image and flash it. There are enough tutorials on that around here.
6: Booting the device first time, but let it be offline and not adding a google account. (Is that right?)
7: Reroot the device. Also enough tutorials.
8: Let Titanium Backup work its magic.
9: Restore data to internal storage.
10: Add google-account.
So, is that right, the right order, did I miss anything? Thanks for your thoughts on this!
