Hello
This Guide to make Dual-Boot for any android device that can be useful. It allows two Android os installed at the same time and switch between them almost as easily as a simple reboot.
Spoiler: General information
This done by creating a new system partition using Parted (shrink userdata partition and creat the new system partition)
To Boot from the new system partition: change the name of the new system partition to "system" and the name of old system partition to any name e.g. "system-b"
To Boot from the old system partition: change the name of the old system partition to "system" and the name of new system partition to any name e.g. "system-b"
Dual boot for P20 lite - demonstration video (I am using SHRP RECOVERY (like TWRP) with tweaks to change boot partition easily, instead of writing terminal commands. This a video shows the dual boot process)
Requirements
TWRP
Parted (attached arm and arm64, unzip the file)
Latest fastboot and ADB commands installed
Backup all your data because you will make a factory reset and format data partition
Steps:
Boot to TWRP
Run the following commands
Code:
adb push /path/to/parted /sbin/parted
adb shell
chmod 777 /sbin/parted
parted /dev/block/mmcblk0
p free
note: parted /dev/block/xxxxx according do your device
3- it will show the list of partition "save this you may use it later". remember the number of old system partition which is in my case "52"
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
4- remove "userdata" partition which in my case number 59 using the following command
Code:
rm 59
5- create the new system partition (partition number 59 in my case ) using the following command
Code:
mkpart name fs_type start end
name: name of new partition e.g "system-b"
fs_type: file system type e.g "ex4"
start: the end value in MB of the previous partition, in my case "7153MB"
end: equal to start + size where size will be the size of the target partition. in my case in need 4GB partition so end=7153MB + 4GB =11153MB
In my case I'll type:
Code:
mkpart system-b ext4 7153MB 11153MB
set 59 msftdata on
6- create the "userdata" partition (partition number 60 in my case, start= 11153MB )
In my case I'll type:
Code:
mkpart userdata ext4 11153MB 31.3GB
set 60 msftdata on
7- get the new partition list
Code:
p free
8- exit
Code:
quit
9- format userdata and the new system partition using "mkfs.type /dev/block/mmcblk0pxx" (in my case partition number 59 and 60). you may need to reboot before doing that or make factory reset using your recovery
Code:
adb push /path/to/mkfs.ext4 /sbin/mkfs.ext4
adb shell
chmod 777 /sbin/mkfs.ext4
mkfs.ext4 /dev/block/mmcblk0p59
mkfs.f2fs /dev/block/mmcblk0p60
10- To Boot from your new system partition > boot to twrp and run the following command
Code:
adb push /path/to/parted /sbin/parted
adb shell
chmod 777 /sbin/parted
parted /dev/block/mmcblk0
name 52 system-b
name 59 system
or from TWRP terminal write the following
Code:
parted -s /dev/block/mmcblk0 name 52 system-b
parted -s /dev/block/mmcblk0 name 59 system
change the number 52 and 59 according to your partition list (in my case 59: new system partion, 52 old system partition ). Then reboot TWRP and flash your new android os
11- To Boot from your old system partition > boot to twrp and run the following command
Code:
adb push /path/to/parted /sbin/parted
adb shell
chmod 777 /sbin/parted
parted /dev/block/mmcblk0
name 59 system-b
name 52 system
or from TWRP terminal write the following
Code:
parted -s /dev/block/mmcblk0 name 59 system-b
parted -s /dev/block/mmcblk0 name 52 system
change the number 52 and 59 according to your partition list (in my case 59: new system partion, 52 old system partition ). Then reboot
-------------------------------------------------------
You may create flashable zip or modify TWRP file to switch between the two android os easily[/CODE]
You can also create two userdata profiles such as here
https://forum.xda-developers.com/t/a-simple-way-to-kind-of-dual-boot-an-android.4176415/
Did you get what you described on your phone and would you like to show it in a video?

Yes. It is worked on my phone Huawei P20 lite ... I am using SHRP RECOVERY (like TWRP) with tweaks to change boot partition easily, instead of writing terminal commands. This a video shows the dual boot process
Flashable zip Files to switch easily between the two android os (you must have "System" and "System-b" partitions, other names not accepted)
Flash "Active-New-System-partition-arm64-v2" to active the new system partition
Flash "Active-Default-System-partition-arm64-v2" to active the default system partition
Anyone else tried this? I'm courious how safe this is... Someone warned me it's very easy to brick device

Is only GSI flashing possible with this method or any custom ROM?
It should work with any GSI/ROM..... It just change the name of the system partition.

look what i got
edit: appearently any name u put when u use the command mkpart doesn't register or smtg idk what's wrong tbh
edit2: i found a solution just do "name 38(in my case) userdata" and it'll name the partition
i accidentally hardbricked my xiaomi pad 5 by deleting the dbg partition (could not find any information about it online), can anybody help?
Does not the new system-b alias requires its own data partition? The new system image may not be compatible with data partition.
New Android OS requires its own data. Above approach will share the /data among different system images which is something not useful.

Yes you can but it does not work with all apps.
I got an app in the Dualboot I made for Oneplus 6/7 series and had an app where you can choose which apps should be shared on both roms.

here is what i did in my sony xperia L and now i anything that can help kindly let me know
I rooted my device and then i officially unlocked my bootloader but after unlocking bootloader the phone was stuck in bootlooop so i installed stock recovery in the phone using flashtool and phone was just fine then. I did all this in order to change the partition of my phone.
Now i installed cwm recovery and after that phone i did the following commands
Open a command window: CMD, then get into shell:
adb shell
Once in shell, type:
umount /storage
parted /dev/block/mmcblk0
print
This prints out the partition information of your phone's memory chip
You will see the partition numbers in the first column, partition names in the last one,
in between you have the start/end memory index and the partition size
------start---end---size
...
31---1795---3506---1711---userdata
32---3506---7818---4312---sdcard
In the above output, consider the values indicated in italic as not to be changed !
Now calculate (open a spreadsheed if you like) the new value for the end of the userdata partition,
and use the same value for the start of the sdcard partition
On your sheet it should look something like this if you added 2048 to the userdata size
------start---end---size
31---1795---5554---3759---userdata
32---5554---7818---2264---sdcard
Remove userdata and sdcard partitions:
rm 31
rm 32
Create the new userdata and sdcard partitions:
mkpartfs logical ext2 1795 5554
name 31 userdata
mkpartfs logical fat32 5554 7818
name 32 sdcard
Exit parted to go to the adb shell again:
quit
userdata partition (31) needs to have ext4 file system
The following will do the ext2->ext4 conversion:
cd /storage/sdcard1/fs-utils
tune2fs -j /dev/block/mmcblk0p31
tune2fs -O extents,uninit_bg,dir_index /dev/block/mmcblk0p31
e2fsck -fpDC0 /dev/block/mmcblk0p31
Now when i restart my phone or even open the phone in cwm recovery it says cannot mount storage.
I tried installing the Rom again using flashtool it does not work and device gets disconnected probably coz now i am not able to mount my storage.
I tried to start adb shell and revert the changes i made in the above command in order to bring phone back to normal but now adb says no device is found.
I went to the customer service centre of sony they said they will change the motherboard.
Now my question is there any way i can fix my phone kindly tell me. I will really appreciate it Since i am not a software developer so i do not know any commands. Is there any way i can change my storage settings so they can be mounted again kindly let me know.

Just a question here, why did you want to change the partition of your phone?_? And no there isnt a way to revert thats a hard brick
Changing the motherboard will be the quickest method for Sony, which will not cause any trouble for them. You could ask the price for doing a low level format and restoring the partitions etc. Though I don't if they can do this in this case.
It is possible to brick your device or future problems caused by this guide
Need flash patched boot image to use parted
1. Download Parted
2.Paste in inside Adb root
3. Boot Twrp
4. Execute in fastboot and adb:
Code:
adb push parted /sbin/parted
adb shell
su (linux users)
cd /sbin && chmod 777 parted
5.
Code:
parted /dev/block/mmcblk0
(start parted)
Parted tutorial
uses "print" and copy results to make backup
Use "help" for list all commands
print - show all partition statuts
Rm (number of partiton) - delete partition
mkpart - create partiton
Code:
[SIZE="4"]exemple:[/SIZE]
mkpart
[FONT="Comic Sans MS"]Partition name?
[/FONT]system_a
[FONT="Comic Sans MS"]File system type?
[/FONT] ext4
[FONT="Comic Sans MS"]Start?
[/FONT] 930
[FONT="Comic Sans MS"]End?
[/FONT]4030
Now we need to name the partitions so the bootloader can find them
name 56
Name?
system_a
type "i" or "ignore" to any messages parted gives you which are warnings and not errors, do NOT type yes if it talks about sectors being moved.
in my case:
Code:
print...
....
56 738MB 3423MB 2684MB ext2 system_a
57 3423MB 6107MB 2684MB ext2 system_b
58 6107MB 6912MB 805MB ext2 vendor_a
59 6912MB 7718MB 805MB ext2 vendor_b
60 7718MB 31.3GB 23.6GB ext4 userdata
Deleted 56 to 60 ,and recrate system to 3.1 Gb, keeping vendor intact, and recrate userdata with what remained
Pos resize:
56 738MB 4239MB 3501MB ext2 system_a msftdata
57 4239MB 7740MB 3500MB ext2 system_b
58 7740MB 8546MB 806MB ext2 vendor_a msftdata
59 8546MB 9352MB 806MB ext2 vendor_b

nop, only to flash large system images like Miui,one ui ....
Do not touch in partitions it if you do not know
this is not proper method.......after this we have to name the partition..without doing this the phone will brick 100%.

Sometimes you are not able to install gapps or other zips from TWRP due to small size of system image.
Here are the steps to increase/decrease the system image size
1. Boot to TWRP and connect your phone through usb cable.
2. unmount system from TWRP
3. commands to execute:
adb shell
e2fsck -f /dev/block/by-name/system
resize2fs /dev/block/by-name/system 4G (Increasing size of system image size to 4gb, you can use any number you want, for example 2500M for 2500mb)
4. Mount the system in TWRP , now you have 4gb system image. check it by:
df system
5. Try installing the gapps or zip again. Done
Refer: https://linux.die.net/man/8/resize2fs
Dont work on Motorola One Power
chef:/ # resize2fs /dev/block/by-name/system_a 3500M
resize2fs 1.43.3 (04-Sep-2016)
The containing partition (or device) is only 655360 (4k) blocks.
You requested a new size of 896000 blocks.

you will need to resize it in fastbootd from the stock recovery.
flash the stock rec then "fastboot reboot fastboot" from bootloader.

I'm having the issue of missing storage with a 32GB phone.
Trying the instructions here - https://forum.xda-developers.com/showpost.php?p=47156078&postcount=2
The issue is the stock recovery doesn't seem to work for me. When you go to recovery mode with it flashed it gets stuck on the android symbol standing up with the spinning gear. I've left this overnight for over 10 hours.
I can resolve this if I flash TWRP recovery which then enables the phone to boot into android setup properly but it then reverts back to the issue of missing storage.
32 become 16 GB, the last last last attempt to solve the issue

I was in the same situation, metod 1, metod 2 any method to fix it did not work
I've solved it by doing this (make this at your own risk, FIRST be sure that your emmc is not damaged):
root your device, and put parted binary ( find it in the forum) in system/bin with execution permission.
Then reboot in twrp recovery, then in twrp recovery terminal or in adb root shell, type this :
Code:
Code:
mount system
umount /dev/block/mmcblk0p28
parted /dev/block/mmcblk0
check 28
it should say something like
Code:
Code:
Error: The backup GPT table is not at the end of the disk, as it should be.
This might mean that another operating system believes the disk is smaller.
Fix, by moving the backup to the end (and removing the old backup)?
Fix/Ignore/Cancel? Fix
Warning: Not all of the space available to /dev/block/mmcblk0 appears to be
used, you can fix the GPT to use all of the space (an extra xxxxxx blocks) or
continue with the current setting?
Fix/Ignore?Fix
answer Fix and Fix.
now type:
Code:
Code:
print
the last two partitions should be:
Code:
28 2032MB 15.8GB 13.7GB userdata
29 15.8GB 15.8GB 5632B grow
if EVERYTHING is like that, let's make a try, type:
Code:
Code:
mkpart primary ext4 15.8GB 25.8GB name 30 trypart
name 30 trypart
print
if you can make trypart without errors and you can see trypart with the print command then
you can proceed to the next step, that will ERASE your data ( worse your userdata partition, before recreating it), type:
Code:
Code:
rm 30
rm 29
rm 28
mkpart primary ext4 2032140288B 31268511743B name 28 userdata
name 28 userdata
mkpart primary 31268511744B 31268517375B name 29 grow
name 29 grow
print
you should see the userdata partition with the new size, and the grow partition after.
Exit from parted by typing
Code:
Code:
quit
Now reboot in fastboot mode and from pc terminal type:
Code:
Code:
fastboot format userdata
ok reboot (wait it take its time) it should be solved.
16 to 32
1.Flash stock rom
2.Wait for opening
3.Reset ur nexus 5 (using options in setting app)
4.*important* Reset when phone boot completely..
