XDA developer and mobile guru Heathcliff, maker of the custom ROM tool "Windows Phone Internals," is working hard leading into the holidays on providing root access to Windows Phone 8.1 and Windows 10 Mobile. This morning, he announced an update to Windows Phone Internals, version 1.1, that fixes at least one pesky issue with the toolset.
This is my Xmas-present for you! Version 1.1 has a fix for the audio-issue when Root Access is enabled and it supports Root Access on the latest Windows 10 Mobile build 10.0.10586.36. You can find the new version of the tool in the Download section.
It seems there were extra integrity checks for playing media. I fixed this for audio-playback. I will create a generic fix later, but this will work for now. If you already have Root Access and you experience the Audio-issue, just "Enable Root Access" again on the phone.
The Android community has long enjoyed custom ROM development based on the general openness of the Android OS, and now Windows phone users can look forward to the same on Lumia devices. We'll be keeping our eye on this development as Heathcliff continues to improve the required tools.
