Getting system permission

[mriscoc]

Warning

Before attempting any system modifications, always make a full backup of your internal uSD card. Check every step twice to ensure it is correct: check file permissions, file names, etc.

This is a complementary procedure. Starting with v0.6.2 two Sparrow apks are provided, the normal and the system version, for install those version the previous one should be uninstalled, the system version has more system access but needs a patched system if you want to have system permissions enabled to, for example, be able to make screen captures from inside of the application.

Important

If you are planning to install the system version apk you MUST first patch the system prior to install the system apk.

Unzip the patched file services.jar file:

services.zip

Then, replace the original one by following this procedure, get ADB from here: https://developer.android.com/tools/releases/platform-tools

adb connect ###.###.###.###:55555
adb root
adb shell mount -o rw,remount /system
adb shell mv /system/framework/services.jar /system/framework/services_jar.orig
adb shell mv /system/framework/oat/arm64/services.odex /system/framework/oat/arm64/services_odex.orig

if you have a previously patched system or found this particular .dex file you must also execute:

adb shell rm /data/dalvik-cache/arm64/system@framework@services.jar@classes.dex

continue by pushing the decompressed patched service.jar into the DHO system:

adb push services.jar /system/framework/
adb shell mount -o ro,remount /system
adb shell sync
adb reboot
