ColorOS和MIUI双系统安装笔记

PS:实在闲的蛋疼，在火车上用手机写的太乱，现在在电脑上修改完善笔记。

本文目的:color os 2.0与miuiV5系统完美共存。

本人实际ROM:Color OS V2.0.47 Beta和miui v5 4.12.12（Xs修改版）
双系统为COS正常刷机，MIUI刷入img文件中
MIUI底包基带版本：MPSS.DI.2.0.1.c7-0020-M8974AAAAANPZM-1
COS底包基带版本：MPSS.DI.3.0.c6-00230-M8974AAAAANAZM-1

一、所需文件：
本文使用的recovery为twrp recovery 2.8.5.1 （recovery.img）
1.1.Color OS和MIUI的ROM(不提供)
1.2.dd.exe(linux指令)
1.3.sed.exe(linux指令)
1.4.busybox
1.5 Color OS和MIUI的驱动底包(Base_Color.zip和Base_MIUI.zip)
1.7 Rashr.apk（刷机工具程序）
1.8 bootimg.exe
1.9清理包（四个）

提取码：eybc

二、准备工作
2.1.生成cache.img,data.img,system.img(推荐大小：100M,3G,1G)

命令：
dd if=/dev/zero of=cache.img bs=1024 count=102400
dd if=/dev/zero of=data.img bs=1024 count=3145728
dd if=/dev/zero of=system.img bs=1024 count=1048576

img存放目录:/data/media/rom/miui/

2.2.修改boot.img(由于我的手机原来系统是COS,所以将提取修改MIUI ROM的boot.img，使得MIUI从/data/media/rom/miui/下img镜像文件启动)。
boot-new.img文件为修改完成后的boot.img

命令：
/*解压boot.img*/
bootimg.exe --unpack-bootimg boot.img

/*修改initrd/fstab.bacon文件中cache,data,system配置*/
sed.exe -i "s:/dev/block/platform/msm_sdcc.1/by-name/system:#/dev/block/platform/msm_sdcc.1/by-name/system:g" initrd/fstab.bacon
sed.exe -i "s:/dev/block/platform/msm_sdcc.1/by-name/cache:#/dev/block/platform/msm_sdcc.1/by-name/cache:g" initrd/fstab.bacon
sed.exe -i "s:/dev/block/platform/msm_sdcc.1/by-name/userdata     /data:/dev/block/platform/msm_sdcc.1/by-name/userdata     /rdata:g" initrd/fstab.bacon

/*
在initrd/init.bacon.rc文件中添加执行语句，
语句作用：
（1）创建挂在点和临时文件系统
（2）利用busybox工具将img挂载到三大分区
（3）修改内置sdcard的配置
*/
sed.exe -i "/mount_all/i    mkdir /rdata 0771 system system" initrd/init.bacon.rc

sed.exe -i "/mount_all/a    exec /sbin/busybox mount -t ext4 -o noatime,nosuid,nodev,nomblk_io_submit,errors=panic,rw /rdata/media/rom/miui/cache.img /cache" initrd/init.bacon.rc
sed.exe -i "/mount_all/a    exec /sbin/busybox mount -t ext4 -o noatime,nosuid,nodev,nomblk_io_submit,errors=panic,rw /rdata/media/rom/miui/data.img /data" initrd/init.bacon.rc
sed.exe -i "/mount_all/a    exec /sbin/busybox mount -t ext4 -o ro /rdata/media/rom/miui/system.img /system" initrd/init.bacon.rc

sed.exe -i "s:service sdcard /system/bin/sdcard -u 1023 -g 1023 -l /data/media:service sdcard /system/bin/sdcard -u 1023 -g 1023 -l /rdata/media:g" initrd/init.bacon.rc

/*复制busybox至内核*/
copy busybox initrdsbin

/*在cpiolist.txt中添加语句，授予busybox 750（rwxr-x---）的权限*/
sed.exe -i "$a file sbin/busybox initrd/sbin\busybox 0750" cpiolist.txt

/*重新打包，生成boot.img*/
bootimg.exe --repack-bootimg

2.3.修改updater-script(由于我的手机原来系统是COS,所以将提取修改MIUI ROM中META-INFcomgoogleandroid中updater-script，使得MIUI ROM刷入三个img文件中)。

命令：
/*删除updater-script默认挂载命令*/
sed -i "/getprop("ro.product.device")/d" updater-script
sed -i "/getprop("ro.build.product")/d" updater-script
sed -i "/mount("ext4", "EMMC"/d" updater-script
sed -i "/format("ext4", "EMMC"/d" updater-script
sed -i "//dev/block/platform/msm_sdcc.1/by-name/boot/d" updater-script
sed -i "//dev/block/platform/msm_sdcc.1/by-name/recovery/d" updater-script
sed -i "//dev/block/platform/msm_sdcc.1/by-name/aboot/d" updater-script
sed -i "//dev/block/platform/msm_sdcc.1/by-name/modem/d" updater-script
sed -i "//dev/block/platform/msm_sdcc.1/by-name/sbl1/d" updater-script
sed -i "//dev/block/platform/msm_sdcc.1/by-name/rpm/d" updater-script
sed -i "//dev/block/platform/msm_sdcc.1/by-name/tz/d" updater-script
sed -i "//dev/block/platform/msm_sdcc.1/by-name/oppostanvbk/d" updater-script
sed -i "//dev/block/platform/msm_sdcc.1/by-name/LOGO/d" updater-script
sed -i "//dev/block/platform/msm_sdcc.1/by-name/reserve4/d" updater-script
sed -i "/unmount/d" updater-script
sed -i "/test.img/d" updater-script
sed -i "/ui_print("Writing radio/d" updater-script
sed -i "/run_program("/sbin/reboot/d" updater-script
sed -i "/run_program("/sbin/busybox", "mount"/d" updater-script
sed -i "/run_program("/sbin/busybox", "umount"/d" updater-script
sed -i "/sha1_check(read_file("/tmp/releasekey")/d" updater-script

/*建立新的挂载命令*/
sed -i "1i run_program("/sbin/mount", "-t", "ext4", "/dev/block/loop2", "/data");" updater-script
sed -i "1i run_program("/sbin/losetup", "/dev/block/loop2", "/realdata/media/rom/miui/data.img");" updater-script
sed -i "1i run_program("/sbin/mount", "-t", "ext4", "/dev/block/loop1", "/system");" updater-script
sed -i "1i run_program("/sbin/mke2fs", "-T", "ext4", "/dev/block/loop1");" updater-script
sed -i "1i run_program("/sbin/losetup", "/dev/block/loop1", "/realdata/media/rom/miui/system.img");" updater-script
sed -i "1i run_program("/sbin/mount", "-t", "ext4", "/dev/block/platform/msm_sdcc.1/by-name/userdata", "/realdata");" updater-script
sed -i "1i run_program("/sbin/mkdir", "/realdata");" updater-script
sed -i "1i unmount("cache");" updater-script
sed -i "1i unmount("data");" updater-script
sed -i "1i unmount("system");" updater-script
sed -i "1i assert(getprop("ro.product.device") == "bacon" || getprop("ro.build.product") == "bacon" || getprop("ro.product.device") == "A0001" || getprop("ro.build.product") == "A0001");" updater-script
sed -i "$a run_program("/sbin/umount", "-d", "/data");" updater-script
sed -i "$a run_program("/sbin/umount", "-d", "/system");" updater-script
sed -i "$a run_program("/sbin/umount", "/realdata");" updater-script
sed -i "$a ui_print("Image Installation complete!"); " updater-script

2.4.准备三清脚本包
自己制作为：
wipe_all_img.zip /*三清包*/
wipe_cache_dalvik-cache_img.zip /*格式化cache.img*/
wipe_data_cache_img.zip /*格式化cache.img和data.img*/
wipe_system_img.zip /*格式化system.img*/

命令：
/*清理data*/
ui_print("Wiping data...");
unmount("/data");
run_program("/sbin/mkdir", "/realdata");
run_program("/sbin/mount", "-t", "ext4", "/dev/block/platform/msm_sdcc.1/by-name/userdata", "/realdata");
run_program("/sbin/losetup", "/dev/block/loop1", "/realdata/media/rom/rootdlhxr/data.img");
run_program("/sbin/mke2fs", "-T", "ext4", "/dev/block/loop1");
run_program("/sbin/mount", "-t", "ext4", "/dev/block/loop1", "/data");
run_program("/sbin/umount", "-d", "/data");

/*清理cache*/
ui_print("Wiping cache...");
unmount("/cache");
run_program("/sbin/losetup", "/dev/block/loop1", "/realdata/media/rom/rootdlhxr/cache.img");
run_program("/sbin/mke2fs", "-T", "ext4", "/dev/block/loop1");
run_program("/sbin/mount", "-t", "ext4", "/dev/block/loop1", "/cache");
run_program("/sbin/umount", "-d", "/cache");

/*清理system*/
ui_print("Wiping system...");
unmount("/system");
run_program("/sbin/losetup", "/dev/block/loop1", "/realdata/media/rom/rootdlhxr/system.img");
run_program("/sbin/mke2fs", "-T", "ext4", "/dev/block/loop1");
run_program("/sbin/mount", "-t", "ext4", "/dev/block/loop1", "/system");
run_program("/sbin/umount", "-d", "/system");
run_program("/sbin/umount", "/realdata");

/*清理dalvik-cache*/
ui_print("Wiping dalvik-cache...");
unmount("/data");
run_program("/sbin/mkdir", "/realdata");
run_program("/sbin/mount", "-t", "ext4", "/dev/block/platform/msm_sdcc.1/by-name/userdata", "/realdata");
run_program("/sbin/losetup", "/dev/block/loop1", "/realdata/media/rom/rootdlhxr/data.img");
run_program("/sbin/mount", "-t", "ext4", "/dev/block/loop1", "/data");
delete_recursive("/data/dalvik-cache");
run_program("/sbin/umount", "-d", "/data");

 

三、操作步骤（貌似还是准备工作比较长，操作比较简单）
3.1.文件操作：
3.1.1cache.img,data.img,system.img三个文件放入手机/data/media/rom/miui目录下
3.1.2将修改后的updater-script文件替换掉MIUI ROM中META-INFcomgoogleandroid中updater-script，再将两个ROM包放入手机sdcard中
3.1.3将各种清理脚本包放入sdcard中
3.1.4将ColorOS的boot.img命名为boot_color.img，MIUI修改后的boot.img命名为boot_miui.img

3.2.刷机操作：
首先，进入recovery，用recovery提供的三清来清理，然后刷入Color OS系统（我们正常的手机系统）
然后，在recovery中刷入wipe_all_img.zip /*三清包*/，然后再刷入MIUI ROM，至此，双系统已经完毕

四、系统切换
4.1.在使用的系统中刷Boot
    安装Rashr.apk,点击“刷写其他内核”，选择对应的boot.img文件(boot_color.img和boot_miui.img)，然后不 要选择重启（因为底包没换，会有写小问题），再选择重启到recovery刷入对应的Base_XXX.zip底包，重启即可。

4.2.在recovery中刷Boot
    在recovery中启动terminal command，选择到boot.img所在文件夹，输入命令：

        dd if=boot_XXX.img of=/dev/block/platform/msm_sdcc.1/by-name/boot

        XXX为对应的系统名（color或miui）

    然后，在刷入对应的Base_XXX.zip底包，重启即可
