I'm new here, and can't get over to the developers forums to ask. I have two GT-I9500s for development purposes, one if full of junk, and the other is still stock, except for recovery. They both have CWM Recovery v18.104.22.168, the latest available pre-compiled I've found. The stock phone has only been booted once. That system is not rooted (and this is my whole point, I want as close to stock as possible)
I am attempting to extract the system image from Stock I9500. I have booted into CWM Recovery mode, then "adb shell" into the device. All commands I issue to the shell return "Permission Denied"
:$ adb shell ~ $ ls /sbin/sh: ls: Permission denied ~ $ dd of=/storage/extSdCard/SYSTEM.img if=/dev/block/mmcblk0p20 bs=4069 /sbin/sh: dd: Permission denied ~ $ su /sbin/sh: su: Permission denied ~ $ sudo su /sbin/sh: sudo: Permission denied
CWM is pure and latest from www dot clockworkmod dot com slash rommanager (new users apparently cannot post links). CWM is able successfully operate "Backup to External" from the stock device.
The end goal is to clone the clean, stock device onto the other one. CWM claims success on "Restore from External" to the other device, but it sits on the "Samsung" loading screen forever.
A solution to either or both of these problems would be appreciated.
