Sorry for not providing more detail.
Over the past year since I purchased helium I have tried it on all of my android devices and at first it worked.
At some point it stopped working on all devices and would not backup to any location.
I tried backup local storage, sd card, dropbox, google drive and to other devices. Nothing works.
I just get a generic error like "helium encountered and error. a copy of the error has been sent to clockwork mod"
I have tried for over a year to get an answer from them and they never reply
I just purchased a new Samsung Galaxy Tab S and wanted to transfer my apps and data. But all I get with helium is the error message above.
Smart switch is from Samsung and it says that it is supposed to transfer from one device to another, such as when you buy a new phone or tablet. However, it transferred the apps but no data was transferred.
Maybe it only works with some apps, not sure. But I do know what any of the apps I tried it with, the data never transferred
