How to Backup when Samsung G S3 not booting stuck at Samsung logo? How to Backup when Samsung Galaxy S3 not booting stuck at Samsung text logo?


I can boot in the "Android System Recovery" Mode using "Volume Up"+"Home"+"Power".
I don't have ADB USB Debug set up.


When using ADB it can get the serial number:



  adb devices -l
  
  List of devices attached
  
  881aa70c       recovery



When using ADB pull to get all SDCard (the built-in 16G memory) - It cannot see any file on /sdcard/



  adb pull /sdcard/ C:\U_adt
  
  pull: building file list...
  
  0 files pulled. 0 files skipped.



When using ADB to pull the /sys/block/ where is the mmcblk0 which is mounted at boot as /SDCard/ it says skipping special file



  adb pull /sys/block/ C:\U_adt
  
  pull: building file list...
  
  skipping special file 'ram0'
  
  skipping special file 'ram15'
  
  skipping special file 'loop0'
  
  skipping special file 'loop7'
  
  skipping special file 'mmcblk0'
  
  skipping special file 'mmcblk0boot1'
  
  skipping special file 'mmcblk0boot0'
  
  0 files pulled. 0 files skipped.



When using ADB backup it says to confirm on the screen, but the phone can not boot to normal where may be the confirmation, and in "Recovery" there is no confirmation message.



  adb backup -shared
  
  Now unlock your device and confirm the backup operation.



I want to backup the DCIM/Camera and other personal data.

How can the backup of pictures on internal memory /sdcard/ can be done?

I read here How do I perform a full pre-rooting backup of an Android phone? that FACTORY RESET does not wipe the data from /sdcard/ internal memory. 

But on my S3 in Android System Recovery the option is named "WIPE DATA/FACTORY RESET". 

Will the option "WIPE DATA/FACTORY RESET" wipe /sdcard/ partition or not?
I used my S3 in "Android System Recovery" 

The option "WIPE DATA/FACTORY RESET" seems to npt wipe /sdcard/ partition. 

in my case it resolved the isue, now the phone is not stuck, and all the apps that were deleted are re-installed from the cloud by Android because I had backup them on the cloud.

Just as a side note, before  I used the above option to get rid of boot stuck on samasung logo, I couldn't use ODIN to install an original firmware downloaded from here:
