I love this book 📚

default.mtz location

=>Under MUI 11
/MIUI/theme/default.mtz

=> Up MUI 12
1. Go to /system/media/theme/default/

2. There are usually files there:

com.miui.home
framework-res
systemui
icons
description.xml

Zip all of that, then change it to Default.mtz

If that folder isn't there, try:

/system/product/media/theme/

🛡️ CustomBase String Encryption (C++)

Protect your native strings and URLs from reverse engineering using libencryption.so a lightweight runtime encryption system for Android NDK projects.

🔧 Features
• Encrypt & decrypt any string in C++
• Custom key (min. 10 chars)
• Ideal for mod menus, API endpoints, update URLs

📂 Setup
1️⃣ Copy libencryption.so to:
app/src/main/jniLibs/arm64-v8a/
app/src/main/jniLibs/armeabi-v7a/

2️⃣ Include the header:

#include "BaseEncryption.h"

3️⃣ Use the API:

std::string dec = BaseEncryption::Decrypt("EncryptedText", "YourKey");
std::string enc = BaseEncryption::Encrypt("https://google.com", "YourKey");

⚙️ Notes
• Key length > 10 characters
• .so must export:
EncryptMessage, DecryptMessage, getEncrypted, getDecrypted
• Rebuild with extern "C" if symbols are mangled

💡 Purpose
Hide sensitive URLs, endpoints, and license data from static analysis tools like IDA, Ghidra, or JADX keep your links safe inside native memory.

SDL Patch to build a 64 bit library

Without this, SDL won't have proper spinlocks on the ARM64 architecture, which can cause crashes. I encountered this issue while working on a project, so I'm sharing it with you guys if you run into the same issue.

File : SDL_spinlock.c

Code :

#ifndef SDL_SPINLOCK_OPT_H
#define SDL_SPINLOCK_OPT_H

#include <stdint.h>


static inline int SDL_AtomicTryLock(volatile int *lock);
static inline void SDL_AtomicLock(volatile int *lock);
static inline void SDL_AtomicUnlock(volatile int *lock);

#if defined(__GNUC__) && defined(__aarch64__)


static inline int SDL_AtomicTryLock(volatile int *lock) {
    unsigned int result;
    asm volatile(
        "ldaxr  %w0, [%1]      \n"
        "cbnz   %w0, 1f        \n"
        "stxr   %w0, %w2, [%1] \n"
        "1:                    \n"
        : "=&r"(result)
        : "r"(lock), "r"(1)
        : "memory");
    return result == 0;
}

static inline void SDL_AtomicLock(volatile int *lock) {
    unsigned int tmp;
    asm volatile(
        "sevl                   \n"
        "1: wfe                 \n"
        "2: ldaxr %w0, [%1]     \n"
        "cbnz %w0, 1b           \n"
        "stxr %w0, %w2, [%1]    \n"
        "cbnz %w0, 2b           \n"
        : "=&r"(tmp)
        : "r"(lock), "r"(1)
        : "memory");
}

static inline void SDL_AtomicUnlock(volatile int *lock) {
    asm volatile("stlr wzr, [%0]" :: "r"(lock) : "memory");
}

#else

static inline int SDL_AtomicTryLock(volatile int *lock) {
    return __sync_val_compare_and_swap(lock, 0, 1) == 0;
}

static inline void SDL_AtomicLock(volatile int *lock) {
    while (!SDL_AtomicTryLock(lock)) {
#if defined(__i386__) || defined(__x86_64__)
        __builtin_ia32_pause();
#elif defined(__aarch64__) || defined(__arm__)
        asm volatile("yield" ::: "memory");
#endif
    }
}

static inline void SDL_AtomicUnlock(volatile int *lock) {
    __sync_synchronize();
    *lock = 0;
}

#endif // defined(__GNUC__) && defined(__aarch64__)

#endif // SDL_SPINLOCK_OPT_H

VirtualApp is an open platform for Android that allows you to create Virtual Spaces, where you can install and run APKs. Furthermore, VirtualApp is also a Plugin Framework, meaning plugins running on VirtualApp don't require any restrictions. VirtualApp doesn't require root; it runs as a local process.

I'm sharing this because the black box project has been discontinued for a long time. So please feel free to develop it yourself.

Alert !
This project distinguishes between 32-bit and 64-bit, it was compiled to 2 different deamon. If you can not find your target in application list, please use another architecture.

Use this SDK to create your own apps.

Alert !
Build Bcore using the source code above to get this SDK.
