Hi!

Which version of sdtools did you use and how large was your SD?

Hi. Thanks for your quick answer. Had tried with 16GB and 32GB and tried with Sdtools 108 and 109.Used two different programs to write it to the SD card. Also  tried to unlock the card. But it ends always with the same result.

Hi again. Could you post what the model number is? And have you tried version 106?
