Trick to remove 10 xap limit and instal unlimited apps

Important : Now uninstall the tool completly from your PC and use any registry cleaner to clean out any residue. (Its conflicts with the WPPT sdk files if left on pc)

Now Install Windows phone power tools or XAP deployer 2.0 To Deploy Xap to the device downloaded from our site.

Now you can download install upto 10 XAPs from our site windowsphonehub..

If it doesnt work do not try anything new by yourself. we are not responsible if you break your device. We still recommend you to unlock using .edu mail account.
Note – Use this tool only to unlock the device. For deploying XAP you should still use Windows phone power tools or XAP deployer 2.0
