Prior to doing a factory reset on my phone, I used Helium to back up all my app data. Now that my phone is reset, I reinstalled helium, and went to restore, but it keeps saying my backup file is invalid. I did the back up through my computer using the Helium server, and I'm trying to restore the same way (by dragging the file into the restore box). I've tried Chrome and Firefox, no luck. I searched around and it seems no one else is having issues backing up this way, any suggestions on how to save my data?
