Command failed: ideviceinstaller -u UDID -l

Hello

As a part of iOS certification, I had updated my iPad Mini 4 to iOS 10 beta 7. I initially had an issue with “could not connect with lockdownd.” when I was trying to push the app with the ideviceinstaller, it was resolved when I had reinstalled Libmobiledevice , but I am facing this issue again

Appium version : 1.5.3
Device: iPad mini 4 iOS `10 beta 6

error at console is : An unknown server-side error occurred while processing the command. Original error: Command failed: ideviceinstaller -u 51fc046b11b88764ad72585f035db5a39b667c0c -l
ideviceinstaller(16943,0x7fff7d0d1000) malloc: *** error for object 0x7f81db607e30: pointer being freed was not allocated

Thanks.
