thx for the quick reply!

Yes, everything should be fine. I have just updated the scripts, you might try it again with this new version.

The functionality is the same, I just changed the text outputs to make it more clear, that this error is not really an issue and additionally the full path to the created backup file is shown...

See the attachment file and let me know, if it is useful to you.

Requirements before running the scripts:

  • Developer Options -> USB Debugging must be enabled
  • Phone must be rooted and root access given for ADB Shell access
  • Phone Drivers must be installed correctly on your OS
  • Connect the phone by USB and run one of the scripts

Reported Devices by users which are working:
  • Galaxy Note 2 GT-N7100
  • Galaxy S4 GT-I9500 (reported by "iznee", thanks)

CHANGELOG - SCRIPTS LAST UPDATED 2013-05-11
  • v3 - Updated text output of the scripts
  • v2 - Updated ADB binary files

Hit the THANKS button if you like it!

Why my scripts?

I was inspired by batch scripts of xda user "as i9000".

But his "Windows" scripts did not satisfy me, because there where file not found issues, and in my opinion missing checks, that made me build up my own scripts from scratch...

gt-I9505xxuamdm....it works:
The file il 128kb...it'ok?
Thanks

Ok,I am sure it is a great script. BUT, how do you open or execute it in windows 8? A (.7z) file extension is unknown to me and windows 8. Forgive my ignorance.

I downloaded a program called "7 Zip" and extracted the script. This is probably a stupid question but where do you run the script? Tried the CMD prompt and the script will run but it does not do anything to the phone. It just runs on the PC and returns an error "file not found". I did have the phone connected in download mode but nothing happened.

Oh, I just read that you have to give root permission to ADB. Apparently you have to run the script in ADB?

Where do I get ADB and how do I run the script in it? Step by step instructions would be much appreciated.
