 # how-to
+## prerequisites
+
+- TWRP and Magisk already being present on the phone
+- access to a Linux shell (WSL also works)
+- ADB + drivers if required
+- Java
+
 ## Android 5-9
+Your system is most likely supported by NanoDroid Patcher and can be patched by flashing the magisk module: https://gitlab.com/Nanolx/NanoDroid
+
+If manual deodexing is still needed, as for example AOSP 9, you can follow the tutorial down below:
+
+1. Boot your phone into TWRP and mount the system
+2. Pull the services.jar from your system
+	- `adb pull /system/framework framework`
+	- on OxygenOS you might need to pull from `/system/system/framework/` or `/system_ext/system/framework/services.jar`
+3. Back up the file
+	- `cp framework/services.jar services.jar.bak`
+4. Determine your architecture
+	- this will most likely be `arm64` but could be `arm` on older phones
+5. Extract the required files with baksmali
+	- `java -jar baksmali.jar x framework/oat/[arch]/services.odex -d framework/[arch] -d framework/ -o services-new`
+6. Patch the extracted files with smali
+	- `java -jar smali.jar a services-new -o classes.dex`
+7. If it was successfully patched, add the new dex to the jar
+	- `zip -j framework/services.jar classes*.dex`
+8. Push the new jar to the device
+	- `adb push framework/services.jar /system/framework`
+	- `adb shell chmod 0644 /system/framework/services.jar`
+	- `adb shell chown root:root /system/framework/services.jar`
+9. Now flash NanoDroid Patcher
 
 ## Android 10
 As far as I know, its not possible to patch the vdex files in OxygenOS 10.
+(for generic Android 10 systems, check here: https://gitlab.com/Nanolx/NanoDroid/-/blob/master/doc/DeodexServices.md#vdex)
 
 ## Android 11
-
+1. Boot your phone into TWRP and mount the system
+2. Pull the services.jar from your system
+        - `adb pull /system/framework/services.jar`
+        - on OxygenOS you might need to pull from `/system/system/framework/services.jar` or `/system_ext/system/framework/services.jar`
+3. Back up the file
+        - `cp services.jar services.jar.bak`
+4. Patch the jar using oF2pks' haystack and his custom OxygenOS hook
+	- `java -jar dexpatcher-1.8.0-beta1.jar -a 30 -M -v -d -o ./ services.jar 11-hook-services.jar.dex 11core-services.jar.dex`
+5. add the resulting dex files back into a new jar
+	- `mkdir -p build/system/framework && cd build`
+	- `zip -j system/framekwork/services.jar ../classes*.dex`
+6. replace the services.jar in spoof_AVDapi30.zip
+	- `cp bin/spoof_AVDapi30.zip .`
+	- `zip -u spoof_AVDapi30.zip /system/framework/services.jar`
+7. flash the module (build/spoof_AVDapi30.zip) through Magisk manager while booted into the system
