Suddenly my HUAWEI (Android 4.2.2) bricked. It stucks at BOOT LOGO. However,when i connect to USB, ADB is able to read phone memory (shell and ls), But the /data directory is not readable (permision denied)

I need contacts (people say it is located in /data/com.android.providers.contacts, but ia m not sure). What to do? i had no backup of contacts, I cant loose them, they are important? WHat's solution ? How to get custom ADBD to do that?

What you read is about correct: contact is stored in /data/data/com.android.providers.contacts/databases/contacts2.db.

You will only be able to read /data if you're rooted. Although Android 4.2.2 should be easily rootable by now, the fact that you're stuck in the boot logo (likely a bootloop) means you can't keep a stable ADB connection, therefore no rooting tools would work (requires stable connection for minutes).

  • It loads ADB well and connection seems stable while USB (just phone is not going to DESKTOP), otherwise connection and directory listing works well. – T.Todua Nov 7 '16 at 7:01

I have tried back and forth, tried to root from SD_CARD; tried to connect to PC using USB + going into FASTBOOT; pulled battery many times while phone was ON (i.e. while in Fastboot, in recovery mode, while powering on...), then tried SP-FLASH-TOOL (while switched of and switched on) and suddenly, after the last try, BOOT SCREEN was not stuck and got to desktop! wow, rare occasion. I have exported contacts immediately!
