# Universal Android Debloater
**DISCLAIMER**: Use this script at your own risk. I am not responsible for anything that could happen to your phone.
## Summary
I try to provide and maintain a universal tool which remove bloatwares on any (non-rooted) Android phones.
The main goal is to improve battery performance and privacy by removing unnecessary and obscure system apps. This can also contribute to improve security by reducing [the attack surface](https://en.wikipedia.org/wiki/Attack_surface). The script has a menu that lets you choose what debloat list you want to use. I strongly encourage you to take a look at the lists because the default selection may not suit you. All packages are as well documented as possible in order to provide a better understanding of what you can delete or not.
This script *should* be safe with the default selection. The worse thing which could happen is preventing an essential system process to be loaded during boot causing then an unfortunate bootloop. After about 5 failed system boots, the phone will automatically reboot in recovery mode and you'll have to perform a FACTORY RESET. So make a backup !
In any case, you can NOT brick your device with this script ! That's the main thing, right ? :smiley:
## Features
* [X] Quick search among all the packages of your phone
* [X] Uninstallation of system/user packages (manually or with the debloat lists)
* [X] Reinstallation of system packages (manually or with the debloat lists)
* [X] ADB backup (not really reliable, see the FAQ)
* [X] Device brand detection and auto-selection of the appropriate manufacturer debloat list
* [X] Logs in `debloated_packages.txt` and `remaining_packages.txt`.
* [ ] Installation of alternative open-source apps replacing stock apps (list in the WIKI section) (WIP)
NB : It is NOT a real uninstallation for system apps (see the [FAQ](https://gitlab.com/W1nst0n/universal-android-debloater/-/wikis/FAQ))

## How to use it
- **Read the [FAQ](https://gitlab.com/W1nst0n/universal-android-debloater/-/wikis/FAQ) !**
- **Do a proper backup of your data ! You can never be too careful !**
- Enable *Developer Options* on your smartphone.
- Turn on *USB Debugging* from the developper panel.
LINUX
- Install *Android plateform tools* and *qpdf* on your PC :
Debian Base :
```bash
$ sudo apt install android-sdk-platform-tools qpdf
```
Arch-Linux Base :
```bash
$ sudo pacman -S android-tools qpdf
```
Fedora :
```bash
$ sudo yum install android-tools qpdf
```
MAC OS
- Install [Homebrew](https://brew.sh/)
- Install *Android plateform tools* and *qpdf*
You will also need to upgrade your bash package because Apple ships a very old bash version (3.2.57) due to licencing issues.
```bash
$ brew install android-platform-tools qpdf bash
```
You have to make the new bash version your default :
```bash
$ sudo echo "/usr/local/bin/bash" >> /etc/shells
$ chsh -s /usr/local/bin/bash
```
Check if it works :
```bash
$ echo $BASH_VERSION
```
WINDOWS
For now, there is no USB support in the WSL. This means you need to install both Windows and linux plateform-tools and force using adb server.
- Download [android platefrom tools](https://dl.google.com/android/repository/platform-tools-latest-windows.zip) and unzip it somewhere. [Add the folder to your PATH](https://www.architectryan.com/2018/03/17/add-to-the-path-on-windows-10/).
- [Install USB drivers of your device](https://developer.android.com/studio/run/oem-usb#Drivers)
- Check your device is detected :
```batch
> adb devices
```
- Install [WSL2 (Windows Subsystem for Linux)](https://itsfoss.com/install-bash-on-windows/) in order to be able to run bash scripts.
- Install *Android plateform tools* and *qpdf* from the Debian/Ubuntu shell
- Download the last version of the script
```bash
$ sudo apt update && sudo apt upgrade
$ sudo apt install android-sdk-platform-tools qpdf
$ wget
```
- Check the version of ADB on linux & windows
```bash
adb version
```
You need the same version otherwise it will not work. It's very likely your Ubuntu/Debian ADB version is older than the Windows one.
Download the lastest linux plateform tools from Google and replace your adb binaries with the new ones :
```bash
$ wget https://dl.google.com/android/repository/platform-tools-latest-linux.zip
$ sudo cp platform-tools/adb /usr/bin/adb
$ sudo chmod 755 /usr/bin/adb
$ adb version
```
kill the WSL adb server and start the ADB server on Windows.
```bash
$ adb kill-server
```
From a windows console :
```batch
> adb kill-server
> adb start-server
> adb devices
```
Note : You can access your Windows files under `/mnt/c/`
- Download [the lastest release of the script](https://gitlab.com/W1nst0n/universal-android-debloater/-/releases)
- Check the debloat lists to be sure the default selection suits you.
- Run `debloat_script.sh` from a Unix terminal
```bash
$ bash debloat_script.sh
```
