My device is a rooted Samsung Galaxy S4 mini (serranoltexx) with CWM recovery.
When I try to take a nandroid backup of my device it gives me the this error:

error while making backup of /data!

Flashing a ROM works fine, is this a permission issue?

  • Is /data successfully mounted when you enter recovery? Check if you can access /data in another way (e.g. adb). If you can then the backup script is broken.

  • Well, my recovery supports neither adb or console line. I forgot to mention that it is a CWM-based Recovery. TWRP doensn't officially support my device and my device was shipped to me with this recovery installed.

  • AFAIK cwm should support adb (at least it did on my phone). Is there any real log file that gives the error a bit more clear then just there was an error ?
