Hi. I just upgraded to 20171011_s12v55_jk_3m.zip, using SPFlashTool,
but did not flash the user data, because I want to keep my settings,
and I did put TWRP in the recovery partition too.
I cleared all cache partitions / cache data via TWRP right afterwards.
But now all apps crash. Even Launcher3 and Play Store.
I managed to get Launcher3 to work, by clearing its data completely.
Which of course deletes my icon layout, groups, widgets and background etc.
[UPDATE:] I now managed to get Play Store to work too, by deactivating it, which told me that it wanted to restore it to the factory version and uninstall the update! So after clearing all data for both the Play Store and Play Services, and reactivating the Play Services (which also activated the Play Store, without asking me), I could start Play Store again.
The problem is that the other apps (e.g. Signal Messenger) fail too. Even when I delete all their data!
I would be forced to uninstall and reinstall them to get them to work. Which is just about equivalent to wiping the user data completely. :/ [/UPDATE]
I have no idea why this is. Shouldn’t Android automatically upgrade that stuff?
I mean, after all, it is meant to work when upgraded via OTA, isn’t it?
I know that when I flash the user data partition too, things “work”.
But all my data is completely gone.
Which makes it pointless, since I will NOT go through all the thousands of settings I configured since I bought the phone!
I want both an upgrade to Android 7, AND keep my settings.
Especially my messenger history and e-mail and cSIPsimple phone settings etc. Because those took forever to get working juust right.
It would take me months to get those working properly again!
Can it be done?
