OPPO.1107刷机笔记

手动 转移任意APP为系统APP的方法流程简述

宗旨: 保持和系统原本同目录下的文件各种设置(权限,所有者,SE上下文),目录结构保持一致即可!

1. 从 /data/app/里将对应的APP文件移动到 /system/app 里.

   Android 5.0 之后的系统在APP目录里可能存在 AppName/AppName.apk 目录等,都需要全部移动走.

2. 设置APP的文件权限为(0644)
3. 所有者为(0:0,root:root)
4. SE上下文为u:object_r:system_file:s0（部分系统开启了SELinux子系统时才需要设置）

5. 重启即可

将任意APP转换为OPPO的Color OS 系统APP方法步骤:

由于OPPO的ColorOS系统定制了系统底层,使之无法识别在系统目录里的非OPPO应用.

所以需要将需要转换的APP包名增加到OPPO应用白名单里才能保证转移后开机识别到.

1. 使用 加密文件 **pl.fs** 生成算法 将任意APP的PackageName包名增加进去得到新pl.fs

2. 将新pl.fs文件替换老的/system/etc/security/pl.fs文件

3. 使用钛备份或幸运破解器或手动将任意APP - 转换为系统应用即可.

包含Oppo所有APP应用程序包名列表的 加密文件 pl.fs 生成算法

try
{
        //生成加密文件
        mOppoApkList.add("cn.asiontang.launcher");
        StringBuilder stringBuilder = new StringBuilder();
        for (String p : mOppoApkList)
            stringBuilder.append(p).append("\n");
        final byte[] bytes = stringBuilder.toString().getBytes("UTF-8");
        for (int i = 0; i < bytes.length; i++)
        {
            bytes[i] = (byte) (~bytes[i]);
            bytes[i] = (byte) (bytes[i] ^ a);
        }
        new FileOutputStream(new File(Environment.getExternalStorageDirectory(), "pl.fs")).write(bytes);
}
catch (Exception e)
{
    e.printStackTrace();
}

ReadEncryptFile 读取 mOppoApkList 关键的解密函数(翻译为JAVA代码)

try
{
    final InputStream open = getResources().getAssets().open("pl.fs");
    byte[] pl = new byte[open.available()];
    final byte[] a = "a".getBytes("UTF-8");
    final int read = open.read(pl);
    for (int i = 0; i < read; i++)
    {
        pl[i] = (byte) (pl[i] ^ a[0]);
        pl[i] = (byte) (~pl[i]);
    }
    final String s = new String(pl, 0, read);
    final String[] split = s.split("\n");
    mOppoApkList.addAll(Arrays.asList(split));
}
catch (Exception e)
{
    e.printStackTrace();
}

为啥无论是通过软件还是手动移植APP到系统System APP目录下都无法生效?同样的手法别的手机却可以.

费尽千辛万苦终于找到原因为:

PackageManager: This is not oppo app, so skip it :/system/app/cn.xx.launcher-1.apk

反编译ROM里的 services.odex - PackageManagerService.java - ColorPackageManagerHelper.java - IsOppoApkList- ReadEncryptFile - 加密的"/system/etc/security/pl.fs"文件

OPPO 1107 移动定制版本的区别 和 刷机包的选择

原来的系统开机启动时会有移动 4G LTE 的LOGO，刷了 1107_11_A.20_OTA_020_all_201512151836.zip 版本(OPPO 论坛官网下载的)之后，就没有了。功能则基本测试都正常。

移动定制版本 1107_11_B.03_XXXXXX ROM版本没公开的市场版本ROM新.就没测试.

SELinux 如何修改权限

1. 使用 ls -Z 可以查看文件的 各种权限

2. 使用 chcon u:object_r:system_file:s0 XX.APK 修改SE上下文

3. 使用 Root Explorer 可以修改所有者,权限,SE上下文.

Root 后卸载 KingRoot 换用 SuperSu 的方法

1. 通过刷机精灵 或者 RootGenius Root精灵 成功 Root 掉 OPPO 1107 设备
2. 此时系统里安装的是 KingRoot APP来管理 Root权限

3. 然后安装第三方 Recovery

   如可通过 'Official TWRP App' APP 即可刷入 第三方Recovery镜像.

4. 然后进入 Recovery 卡刷完整 ROM包 1107_11_A.20_OTA_020_all_201512151836.zip

5. 在重启时,会提示"是否禁止还原到官方Recovery" 选择 "否"

   如果选择是,则第三方 Recovery 还将保留,但是 无法进入下一个选择"是否Root"的界面了.

6. 然后弹出"是否Root" 选择 "是"

7. 重启之后,安装 SuperSu APP即可.
