To perform a NANDROID backup via cwm your phone needs to be rooted first. If you are unlocked then you can just select the root option and once its complete you can then boot into cwm and do your backup.
Your NANDROID will of course backup your root files but 'I think' if you restored the image and then locked your bootloader and unlocked it again (thus doing a full wipe) it may unroot the phone in the process but I have never tried it.
Thank you. I apologize for any inconvenience it may cause as I am usually more cautious when dealing with ROMs of any type.
To confirm, the correct sequence for backing up the ROM without flashing are:
1. Install Galaxy Nexus Drivers to your PC
3. UnLock your Bootloader
4. Root your phone
9. Boot to CWM Recovery without Permanently Flashing it
Would you please tell me where I can locate the back-up file?
Besides, is the superuser.apk permanently installed in the phone or do I need to install the apps seperately?
Thank you for your ongoing support.
Thank you. After I have rooted the phone, the error messages have disappeared.
Before I select backup & restore under the insecure CWM, should I:
1. wipe data/factory reset?
2. wipe cache partition?
3. Advance - Wipe Dalvik Cache?
After the insecure CWM back-up is completed, what steps do I need to take to pull the file out from the phone?
Thanks. This is probably my last question. Do I need a file manager, e.g. root explorer, File Expert by Geek Software Technology Inc, etc to locate the file on the phone and transfer to my computer.
Is the File Expert by Geek Software Technology Inc sufficient for an average user?
