I have a Sony Xperia U which worked fine. I did not change anything lately.

Today all apps crash on startup. Even Play Store, com.google.process.gapps and android.process.acore. The media gallery seems empty too. Whenever I start something, it crashes, except for opening system settings.

When I connect my phone with my computer the internal storage seems completly empty - so I can't backup anything.

Is there anything I can do to recover my phone and to keep my data like pictures, contacts, ...? *

I tried the save mode, but the erros occur there too.
I tried to boot in Recovery Mode, but all button combinations did not work. I also tried in USB debugging mode using ADB, but that did not work too.

* Since Play Store is not working I can't install any backup tools.

  • Is the device rooted?

  • No, sadly it's not.

  • OK, that leaves no much options. Still: Try booting into recovery and wiping CACHE (only that, not data!). Sometimes things go weird there. Doesn't hurt, no data loss – so you only can win. Or lose some time.

  • @Izzy: I tried everthing: Power+VolUp Buttons while booting, Power+VolDown, Power+VolUpDown, kept pressing or pressing multiple times. The phone just boots normal

  • (Google-Fu-Ah!) You might wish to use these instructions: How to Boot Into Sony Xperia U Recovery Mode. Seems to be a question of timing. Basically, wait until the LED changes its color, then start hammering the volume key.

Try booting into recovery and backup there if you have an option. If not, then wipe it there or with the key combination: Volume Up+Home+Power Source: www.phonetipsandtricks.com/tips/sony-xperia-u/hard-reset-factory-reset-14/
