# Deodex services.jar
|
|
|
|
Here you can find instructions on how to manually deodex `services.jar` as preparation for Signature Spoofing support.
|
|
|
|
If you want to check beforehand (or afterwards), if your ROM supports Signature Spoofing, use this [tool](https://f-droid.org/de/packages/lanchon.sigspoof.checker/).
|
|
|
|
## Pre-Check
|
|
|
|
If your `/system/framework/services.jar` file contains the file `classes.dex`, you can skip deodexing and start patching right-away, else following theese instructions.
|
|
|
|
## Android 9.0 Pie
|
|
|
|
Android 9.0 is currently not supported by smali/baksmali (more precisely O/DEX format 039 and OAT format changes are not yet implemented).
|
|
|
|
VdexExtractor will create CompatDex for Android 9.0 (more precisely VDEX 019 files) instead of DEX. Theese CDEX files can only be manually converted to DEX on a GNU/Linux or MacOS PC, see [this instructions](https://github.com/anestisb/vdexExtractor#compact-dex-converter).
|
|
|
|
## VDEX
|
|
|
|
If you can see `/system/framework/oat/[arch]/services.vdex`, where [arch] is the device architecture (arm, arm64, x86 or x86_64), you should follow theese instructions.
|
|
|
|
the instructions are basically simple, though plenty commands:
|
|
|
|
* connect phone with PC while in TWRP, mount `/system` **read-write**
|
|
* get latest `vdexExtractor`
|
|
* [vdexExtractor Sources](https://github.com/anestisb/vdexExtractor)
|
|
* zip/unzip utilities for commandline (or some UI tool)
|
|
* common sense on using commandline (or some UI tool instead)
|
|
|
|
```
|
|
adb pull /system/framework framework
|
|
cp framework/services.jar services.jar-backup
|
|
```
|
|
|
|
now deodex `services.vdex`:
|
|
|
|
```
|
|
vdexExtractor -i framework/oat/[arch]/services.vdex --ignore-crc-error
|
|
```
|
|
|
|
this will create the following file:
|
|
* framework/oat/[arch]/services.apk_classes.dex
|
|
|
|
if it's properly been created rename it to classes.dex and add it to `services.jar`, if there are additional files like services.apk_classes2.dex, rename them to classes2.dex and so on and add them to services.jar like:
|
|
|
|
```
|
|
mv framework/oat/[arch]/services.apk_classes.dex classes.dex
|
|
... mv for other dex files ...
|
|
zip -j framework/services.jar classes*.dex
|
|
```
|
|
|
|
next install the new `services.jar` to device:
|
|
|
|
```
|
|
adb push framework/services.jar /system/framework
|
|
adb shell
|
|
chmod 0644 /system/framework/services.jar
|
|
chown root:root /system/framework/services.jar
|
|
```
|
|
|
|
unmount `/system` and flash the NanoDroid-Patcher.
|
|
|
|
If something goes wrong you still have the unpatched `services.jar`, as we created a copy named `services.jar-backup`.
|
|
|
|
## ODEX
|
|
|
|
If you can see `/system/framework/oat/[arch]/services.odex`, where [arch] is the device architecture (arm, arm64, x86 or x86_64), you should follow theese instructions.
|
|
|
|
the instructions are basically simple, though plenty commands:
|
|
|
|
* connect phone with PC while in TWRP, mount `/system` **read-write**
|
|
* get latest `baksmali.jar` and `smali.jar`
|
|
* [smali Sources](https://github.com/JesusFreke/smali)
|
|
* zip/unzip utilities for commandline (or some UI tool)
|
|
* common sense on using commandline (or some UI tool instead)
|
|
|
|
```
|
|
adb pull /system/framework framework
|
|
cp framework/services.jar services.jar-backup
|
|
```
|
|
|
|
```
|
|
java -jar baksmali.jar x framework/oat/[arch]/services.odex -d framework/[arch] -d framework/ -o services-new
|
|
java -jar smali.jar a services-new -o classes.dex
|
|
```
|
|
|
|
somestimes baksmali.jar can't find the bootclasses file itself, in this case pass it manually using `-b`, for example:
|
|
|
|
`-b framework/[arch]/boot.oat`
|
|
|
|
in any case, if a new classes.dex was successfully created in the services-new directory, re-package it into the services.jar we previously pulled:
|
|
|
|
```
|
|
zip -j framework/services.jar classes*.dex
|
|
```
|
|
|
|
next install the new `services.jar` to device:
|
|
|
|
```
|
|
adb push framework/services.jar /system/framework
|
|
adb shell
|
|
chmod 0644 /system/framework/services.jar
|
|
chown root:root /system/framework/services.jar
|
|
```
|
|
|
|
unmount `/system` and flash the NanoDroid-Patcher.
|
|
|
|
If something goes wrong you still have the unpatched `services.jar`, as we created a copy named `services.jar-backup`.
