I was to turn in my phone (Sony Xperia Z1 compact) for a warranty issue (battery acting up). The guy in the store told me there would be a factory reset at the service point so I went home, used the built in Sony approved "Backup & Restore" app (with current experience - DO NOT USE IT!!!). To be safe I created 3 different restore points (just in case) and stored to my SD card. I backed up everything, contact list, messages, photos etc using the sony app. To be extra safe I did install the google + app to backup my contact list (wich of course also failed, it only backup up 6 of my ~500 contacts, don´t ask me why).
Got the phone back today. Battery replaced (nice!). Software upgraded - Didn´t ask for that but lets see. Went home. Popped in my SD card with my restore points, selected to restore and got the message: "Cannot restore - Selected backup records cannot be used du to incompatible software versions. Please select a more recent backup file". After searching the internet and spending an hour chatting with the sony support it seems I´m pretty much screwed. That (useless) app appears to ONLY be working if used on the exact same phone model with the exact same OS version.
The guy at Sony tells me that the only way to handle this is to unlock the boot loader wich will void my warranty. I asked if it was possible to just pull the contacts and messages from the backup file but no, according to him that app stores the backup up stuff in a non-typical way wich is impossible to reach unless you have the correct version on the phone.
It seems like there are a lot of smartheads in this forum, does anyone have an idea on how to either pull the vital data from the backup or any other idea? The boot loader unlock option is not very tempting since it will void my warranty, not give me automatic updates in the future and on top of that there is a risk I´ll screw up my phone for good.
As a last comment, it would have been nice if the App informed you about the fact that it would only work on the same OS-version, that would for sure have made me think twice and made at least one backup using another system but no. I found threads about this as early as december 2013, still users will continue to loose all their data. A simple popup with that information would save a lot of people a lot of headache.
