Cyanogen mod 9, ClockworkMod Recovery

I recently plugged in my phone after the battery completely died over night and the phone is stuck in a bootloop. I left it trying to boot for 30 minutes and it's just stuck.

I've made a backup in clockworkMod recovery and am willing to flash the phone to a newer or the same version of cyanogen but I don't want to lose data.

Is there any way I can make sure my contacts and SMS messages are recovered?

  • Before you go hard-core: have you checked with the boot-loop tag-wiki for possible remedy? Have you tried to remove the battery for a few minutes, then re-insert and boot up again? Have you cleaned up cache and Dalvik-cache from CWM?

    Yeah I did all of that. Battery out for a while. Cache clearing, everything I could find.

  • OK, was just a thought. Can you boot into recovery? Not sure if adb backup is available there as well, but you could give it a try then. For SMS, com.android.providers.telephony should be the one to backup, for contacts com.android.providers.contacts if I remember correctly.

  • @izzy can boot into recovery, no adb backup though :(

  • OK. Try adb shell and see if you can access e.g. /data/data/com.android.providers.contacts (needs root). If so, you could at least adb pull the two directories and, if you flash the same ROM again or simply do a factory-reset, might be able to adb push them back, followed by a reboot so the corresponding services pick up the changed data. You could also try to adb pull the entire /data/data directory with settings etc. of all your apps, just in case ;)

I reinstalled android and lost all my data. Nothing else worked. :(


I recently went through this, and it is possible to restore your data, take a look at my own experience at Extract App Data from Nandroid / CWM Backup. Basically you can use Nandroid Manager to restore the data you have backed up. But I am not sure if I got all the data of the apps that might have been installed to sdcard though, so if you can, take a backup including those apps as well (maybe too late now). Hope you still have that backup.. just noticed the date :(
