A customer brought me a WM8650 with a battery drain issue. After researching on how to replace the battery it was clear that I wanted to first try a battery calibration as the video showed that you have to pretty much destroy the screen cover to get to the battery. Also, there were no clear links on where in the world one could order batteries for this particular device. So I downloaded battery calibration software but it requires root. Well the typical means of rooting don't seem to work and it seems that the only way to root it is by flashing a new ROM? I really don't care to have to flash this to a new ROM, unless that's the ONLY means to root the device. I know a new ROM might give some other benefits but it seems to be a bit overkill in order to run battery calibration software.
