I have the same problem when using Master Control Panel in Android (stops at 27% and fails). I using softdevice 7.0.0-3 and SDK 6.</p> <p>The DFU OTA upload works fine if I do it through Master Control Panel 3.5.1 on my PC. I tried to change the MRB size to 0 on the application as suggested on the forum, but no success... (Actually if I don&#39;t change the size to 0, the upload fails immediately).</p> <p>Your help would be really appreciated !</p><div style="clear:both;"></div>
