+===== Latest System Software  =====
+Actually I'm running my Gretel A7 with the following configuration:
+  * **TWRP Recovery 3.0.2** - We use version 3.0.2 because we had problems with newer 3.2.1, [[#installing_the_xenonhd_custom_rom|see below]]. NOTICE: When you flash the recovery image, do not reboot normally, otherwise the partition will be overwritten. From poweroff, reboot instead into //Select Boot Mode Menu// and choose Recovery.
+  * **Stock ROM 20170908** - We found on the net the archive Y8303.YX.A7.Gretel.B1B8.6.0.V01.07.20170908.rar. Beware that this stock ROM contains a trojanized launcher! [[#infected_stock_rom_20170908|See below]]. It features Android 6.0, with security patch level August 5, 2015.
+  * **SuperSU v2.82** build number 20170528234214 - Needed to gain root privileges and replace the launcher.
+  * **Rootless Pixel Launcher 3.9.1** - Downloaded from F-Droid repository, replaces the trojanized default launcher.

 **NOTICE**: If you enable a **Google account**, you will find a new application installed into **/data/app/com.google.android.gms-1/**, do not remove it because it is the **Google Play Services** required to access the Play Store, etc.
 ===== Immersive Mode =====
+:!: **NOTICE**: No need to install a dedicated app to have Immersive Mode for one App, just use the command **settings put global** from an **adb shell**, as explained below!
 Questo smartphone Android ha il solo pulsante fisico //Home//, i pulsanti //indietro// e //menu// sono virtuali ed **occupano la parte bassa dello schermo**. La cosa è noiosa per i programmi che avrebbero vantaggio ad usare tutto lo schermo, come un programma di navigazione GPS.

 In this exampled we configured **net.osmand.plus** to run in **full immersive** mode **hiding the Status Bar** at the top of the screen and **hiding the Android Navigation Bar (Soft Keys)** at the bottom.
-You can instead use the **immersive.status** setting if you want to keep the top Status Bar.
+Beside the **immersive.full** you can use the **immersive.status** setting if you want to keep the top Status Bar and the **immersive.navigation** if you want to keep the Navigation Bar only.
-The setting will survive the phone reboot.
+The setting takes effect immediately, even if the app is running! The setting will survive the phone reboot, you can confirm from an adb shell:
-FIXME How to revert to normal state?
+<code>
+settings get global policy_control
+immersive.full=net.osmand.plus

+To delete the settings:
+<code>
+settings delete global policy_control

+If you want to set the immersive mode for two application you have to use a comma separated syntax: **immersive.full=com.package.one,com.package.two**.
