@aashaup, sorry to know that you deleted your original form from the server. If this is the case, kindly be informed that the system will not allow you to upload data from your device as the system will not be able to match the form version (that was first deployed, which is in your device but now which has been changed on the server).
So in this case, the only available option is that you can extract your collected data using the ODK Briefcase as outlined in this post discussed previously:
