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? – Izzy Aug 22 '14 at 20:26
  • No, sadly it's not. – juergen d Aug 22 '14 at 21:06
  • 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 Aug 22 '14 at 21:14
  • @Izzy: I tried everthing: Power+VolUp Buttons while booting, Power+VolDown, Power+VolUpDown, kept pressing or pressing multiple times. The phone just boots normal – juergen d Aug 23 '14 at 1:46
  • (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. – Izzy Aug 23 '14 at 12:12

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/

  • I am looking for a way to keep my data and not to reset everything – juergen d Aug 22 '14 at 19:17
  • deviceguides.vodafone.ie/web/sony-xperia-u/customise/software-update/back-up-phone-memory/ maybe this way? – Laszlo L. Mári Aug 22 '14 at 22:36
