Install MIUI ROM on your phone with Dual Boot

Please pay attention! We are not responsible for any issues with your device. You do everything at your own risk.

First of all you’ll need to download Notepad++ and Android Image Kitchen: Android.Image.Kitchen.v2.7-Win32.zip

1. Grab boot.img file from downloaded MIUI ROM and drag-n-drop to unpackimg.bat file.
2. You’ll see two folders after unpacking “ramdisk” and “split_img”.
3. Use Notepad++ open “default.prop” and add the following lines or change existing ones:

   ro.miui.has_cust_partition=true
   ro.secureboot.devicelock=0
   ro.secure=0
   security.perf_harden=0
   ro.allow.mock.location=0
   ro.adb.secure=0
   ro.debuggable=1
   persist.sys.usb.config=mtp,adb
   persist.service.adb.enable=1
   persist.service.debuggable=1

4. Next open “fstab.qcom” and remove “verify” if you’ve see any:

   /dev/block/bootdevice/by-name/system         /system      ext4    ro,barrier=1,discard                                wait

5. Open “init.rc” and add the following lines to the bottom:

   #service for shelld
   service shelld /system/xbin/shelld
       class main
   
   #service for su
   service su_daemon /system/xbin/su --daemon
       class main
       oneshot

6. In “init.qcom.rc” find “on property:sys.boot_completed=1” line and add the following above it:

   service shelld /system/xbin/shelld
       class main

7. Delete “emmc_appsboot.mbn” file in “firmware-update” folder.
8. Go to “ROMFOLDER\META-INF\com\google\android” and edit “updater-scrypt” file. Delete the following 6 lines:

   package_extract_file("META-INF/com/miui/miui_update", "/cache/miui_update");
   set_metadata("/cache/miui_update", "uid", 0, "gid", 0, "mode", 0555, "capabilities", 0x0);
   run_program("/cache/miui_update");
   delete("/cache/miui_update");
   show_progress(0.600000, 120);
   ui_print("Patching system image unconditionally...");

9. Delete these lines:

   package_extract_file("firmware-update/emmc_appsboot.mbn", "/dev/block/bootdevice/by-name/aboot");
   

10. Delete the last one:

    package_extract_file("firmware-update/emmc_appsboot.mbn", "/dev/block/bootdevice/by-name/abootbak")

11. And finally delete “miui_update” file from “ROMFOLDER\META-INF\com\miui”.
12. That’s it! We’ve finished editing boot.img file.
13. Now press on “repackimg.bat” to make the new one, the image-new.img file will be created. Rename and replace the original boot.img file in rom folder.
14. Now use WinRar and WinZip to make archive the unpacked rom.
15. The MIUI ROM is now ready to use with TWRP or DualBootPatcher.

Here’s a very simple guide on how to patch Dual Boot rom on your Redmi Note 2 device. I’m making this guide using Dual Boot Patcher 8.0.0.r2709.g554d8f9-SNAPSHOT.

Remember that you do everything at your own risk!

Dual Boot Patch install steps:

1. Download rom (link below)
2. Run DualBootPatcher
3. Select “Patch zip file”
4. Select the patch rom file. Make sure you turn on “Documents” application. It is at the end of the list. Just in case, it may be disabled
5. Select device and partition configuration. Important: If you have selected a memory card, there will be created an .img file (it takes around 15-20 minutes, quite a lot actually)
6. Put a partition name (this name will be shown later in the main menu)
7. Choose a file name for the Dual Boot patch file (usually it is setup automatically “firmware slot-slot-name”)
8. Prepare the patch rom
9. Now go to the “Roms”
10. Click “+”, then again “+” and select the the patched rom. Then change the location for the rom or leave the slot as is.
11. Wait for the process to complete. In the end you’ll see “1/1”. This mean that installation is successfully completed. If the patcher is flashed with a different kernel, there will be “Setting kernel” message.
12. Next (if everything is successful), you will see the patch image and its characteristics (Android version and build name).
13. Restart and wait for the first startup.

Downgrade or flash if you have no root, but have TWRP:

Here’s how you return your device to previous rom version. TWRP 3.0.2 by Jemmini.

1. Download Dual Boot (Utilities) and save them to anywhere.
2. When you first start the recovery will ask you to edit system partition – “Keep System Read only?”. On the “Unmodified System Partition” screen, select “Never show this screen during boot again.” and swipe to allow.
3. Enter Setup section and select “Install”
4. Look for and select the utilities file DualBootUtilities-8.0.0.r2709.g554d8f9.zip
5. Aroma Installer will be launched
6. Device information will be displayed, click “Next”
7. Select your main rom.
8. Press”Switch to”
9. In the log you should see “Exit code: 0”, press “Next”
10. Press “Finish”
11. “Reboot” and wait while rom loads.
