After updating to 5.0.1, I had bad problems with wifi connections. After trying every possible solution without success, I decided to do a backup and reset. First though, I copied both the card and phone folders to my laptop. After the reset, the wifi problem seems to be fixed, but now all the contacts are gone. For whatever reason, they were not synced with my google account. Can I find the contct data somewhere in the folders that I copied onto my laptop? Thanks in advance for any help. Simon
Maybe this post is useful for you: https://android.stackexchange.com/a/41459/31639
Basically you could try searching the sqlite database location under
By default it's
/data/data/com.android.providers.contacts/databases (at least for me (currently running GPE on my GS4))
Anyway, just copying some folders from internal storage is far away from a correct way of backing up contacts etc. and if your contacts would be stored in your Google account they would've been automatically imported again after relinking your Google account to your device.
If you gained back access to your contacts you should check the correct storage of your them and move them to your Google account if necessary.
