# Google Photos unlimited backup module
Adds Photos features and unlimited original backup

Current version : **1.1-stable** [Download from releases](https://git.disroot.org/cuynu/gphotos-unlimited-zygisk/releases)

### [Chuyển ngôn ngữ Tiếng Việt](https://git.disroot.org/cuynu/gphotos-unlimited-zygisk/wiki/VI)

# Introduction 
Based from Pixelify GitHub. This module will spoof your device info to Pixel XL on Google apps and Google Photos to get unlimited backup storage at original quality !

# Warning !
Module will only works with Zygisk, it will not works with Riru, Shamiko, etc !!

Some modules could break and prevent this module from running, if module does not work, try disable some modules and see.

# Usage 
Download module from [release page](https://git.disroot.org/cuynu/gphotos-unlimited-zygisk/releases), enable Zygisk then install with Magisk v24.3+ and reboot. 

For KernelSU/KernelSU-Next/RKSU/APatch users, **DON'T use ZygiskNext 1.0.0+** !. Instead, use [ReZygisk](https://github.com/PerformanC/ReZygisk/releases). 
- Tested with : `Magisk v25.2+` `Magisk Delta/Kitsune` `KernelSU` `KernelSU-Next `APatch`

# Known issues 
- **Some Xiaomi devices with MIUI 14 when this module is active, its will cause Bootloop with SystemUI crash exception**
- When use with `Magisk-GApps` module, it will conflict and cause lose the ability to backup unlimited at original quality (Still able to backup unlimited at storage saver quality)

# Tested devices
- Sony Xperia XZ2 (Stock Android 10, LineageOS 18.1,19.1,20.0,21.0,22.2)
- Redmi Note 7 (MIUI 12.5 CN, Nusantara EOL A10)
- Google Pixel 2 (Android 11 stock)
- Masstel_X9 (Stock Android 9, LineageOS 18.1/19.1)
- LG G7 ThinQ (Stock Android 10, LineageOS 21.0/22.2)
- Vsmart Joy 2+ (LineageOS 20.0)

# ToDo
- Rewrite hook library in C++ and take it away from Pixelify (as long as i learn C++ :>)

# Build zygisk binary
`git clone https://git.disroot.org/cuynu/gphotos-unlimited-zygisk.git`

Import folder zygisk_build to Android Studio or Gradle and build then copy compiled zygisk library to zygisk folder (not zygisk_build)

/*

***************
* Introduction
***************

On Android, all app processes are forked from a special daemon called "Zygote".
For each new app process, zygote will fork a new process and perform "specialization".
This specialization operation enforces the Android security sandbox on the newly forked
process to make sure that 3rd party application code is only loaded after it is being
restricted within a sandbox.

On Android, there is also this special process called "system_server". This single
process hosts a significant portion of system services, which controls how the
Android operating system and apps interact with each other.

The Zygisk framework provides a way to allow developers to build modules and run custom
code before and after system_server and any app processes' specialization.
This enable developers to inject code and alter the behavior of system_server and app processes.

Please note that modules will only be loaded after zygote has forked the child process.
THIS MEANS ALL OF YOUR CODE RUNS IN THE APP/SYSTEM_SERVER PROCESS, NOT THE ZYGOTE DAEMON!

*********************
* Development Guide
*********************

Define a class and inherit zygisk::ModuleBase to implement the functionality of your module.
Use the macro REGISTER_ZYGISK_MODULE(className) to register that class to Zygisk.

Example code:

static jint (*orig_logger_entry_max)(JNIEnv *env);
static jint my_logger_entry_max(JNIEnv *env) { return orig_logger_entry_max(env); }

class ExampleModule : public zygisk::ModuleBase {
public:
    void onLoad(zygisk::Api *api, JNIEnv *env) override {
        this->api = api;
        this->env = env;
    }
    void preAppSpecialize(zygisk::AppSpecializeArgs *args) override {
        JNINativeMethod methods[] = {
            { "logger_entry_max_payload_native", "()I", (void*) my_logger_entry_max },
        };
        api->hookJniNativeMethods(env, "android/util/Log", methods, 1);
        *(void **) &orig_logger_entry_max = methods[0].fnPtr;
    }
private:
    zygisk::Api *api;
    JNIEnv *env;
};

REGISTER_ZYGISK_MODULE(ExampleModule)

-----------------------------------------------------------------------------------------

Since your module class's code runs with either Zygote's privilege in pre[XXX]Specialize,
or runs in the sandbox of the target process in post[XXX]Specialize, the code in your class
never runs in a true superuser environment.

If your module require access to superuser permissions, you can create and register
a root companion handler function. This function runs in a separate root companion
daemon process, and an Unix domain socket is provided to allow you to perform IPC between
your target process and the root companion process.

Example code:

static void example_handler(int socket) { ... }
