I’ve been able to move most of my apps fairly easily when updating Android tablets or smartphones but a couple of King Games have issues. For Bubble Witch Saga 2 and Candy Crush Soda Saga, you can save your progress by connecting to Facebook but you end up loosing all your boosters. The only way to keep your boosters is to back up application data with the Helium app.
Connecting with the Helium app has always been tricky. You have to make sure you have the correct USB drivers. For my new Asus Z300M tablet, the initial drivers that were found indicated problems with MTP but when I let Windows update search for the latest drivers online, it appeared to find the latest ones. In device manager, the driver showed no errors but Helium still would not connect and would show “Waiting for Device” .
Under Device Manager, the tablet shows up as “ASUS Android Composite ADB Interface”.
After several attempts at switching between MTP and PTP modes and toggling USB debugging on and off, I decided to try to run adb.exe in command mode to see if my computer could talk to the tablet.
I opened up a command window (Start Menu->Search box->type cmd) and entered “adb devices” at the command prompt. The PC found the device and a window popped up on my tablet with “Allow USB Debugging? The computer’s RSA fingerprint is XX:XX:XX:XX:XX:XX:XX” Once I hit ok, Helium connected successfully.
If your drivers don’t report errors (not listed under the question mark in Device Manager), try this.
