** Warning **
- Please backup your data before proceeding.
- This is a test build! While it may function as expected, it is meant for debugging purposes.
- Not for the faint hearted. This is Beta software. If something goes wrong, you might lose your data and might have to re-flash EEA 1 (SW6 - EU) using SP Flash software.
- Few apps might not be available in the App store like Netflix, Disney+ (this is due to the build not yet certified by Google).
We have tried to resolve the issues regarding roaming indicators, and incorrect statusbar signal-cluster icons in this build. However, we would like to gather some more logs on the same. This build contains added logging that will help us better understand issues on various carriers. If you had these issues earlier, we’d recommend trying this build. Should the issue persist, we may ask for logs, so we can resolve it at the earliest.
Following the release of Teracube 2e’s SW16 build, this update should bring the fixes and goodies of SW16 to EU users. As mentioned earlier, this update is not GMS certified yet.
