Creation date: February 2021
Updated: January 2023

Requirements:

rooted STOCK Android 10 or newer
at least 10+ GB free space on phone for dumping data

Description:

A script for all Android power users that wish to make their read-only Android 10+ system read/write-able again to remove bloatware and make more thorough customizations to their device.

Script only modifies super and vbmeta partitions. /data partition is not affected. It's only used for dumping data and for storing script files.

In a nutshell this is what the script is doing:

dumps your existing super partition
extracts embedded read-only sub-partitions (system, system_ext, odm, vendor, product...) from specified super image
makes these sub-partitions read/write-able using the one and only original MakeRW/ro2rw algorithm
joins everything back together to new super.img
flashes read/write-able patched super image back to device using the super fast Kolibass technique (only available in recovery mode)

NOTE:

The script can be run both inside custom recovery and inside Android operating system.
If you run script in Android mode you will need to fastboot flash the patched image(s) manually!

To check whether or not the script worked correctly you can run this code:

Bash:

adb shell
su
mount -o remount,rw /
mount -o remount,rw /odm
mount -o remount,rw /product
mount -o remount,rw /system_ext
mount -o remount,rw /vendor
mount | grep dm- | head -5

Manual installation:

Extract flashable.zip and copy sysrw_*VERSION* folder into /data/local/tmp/
run this command to make the script executable:
chmod +x /data/local/tmp/sysrw_*VERSION*/sysrw

Automatic installation:

Installation of the script has never been this easy!

Download the flashable.zip below, do NOT enable zip signature verification and simply install it in your custom recovery (works in TWRP, OrangeFox and PBRP!)

The update binary will auto-detect the arguments in config.ini and launch the script accordingly

Flashable zip custom usage:

You can easily modify the custom script execution arguments in the included config.ini file. Simply extract the flashable.zip, edit the included config.ini file with notepad and then save the file. Next compress the sysrw_*VERSION* and META-INF folders again as a new flashable .zip and install it in recovery. Have fun playing around with your config.ini

Script usage:

Simply execute the program from the terminal shell with or without custom arguments

Optional script arguments:

Replace x with your custom value

in=x
Specify existing super image as input [OPTIONAL]
Omitting this parameter is equivalent to using in=@auto which is equivalent to using your super block device as input
out=x
Specify patched super image output file path [OPTIONAL]
Omitting this parameter is equivalent to using out=@auto and the patched super image will be saved as ./img/super_patched.bin by default
size=x
Specify the extra free space (in megabytes) to be added to each sub-partition of super.img [OPTIONAL]
Omitting this parameter is equivalent to using size=@auto which will activate the auto-resize feature
-r
Specify whether or not the patched super image should be output in raw file format [OPTIONAL]
Omitting this parameter will create a sparse patched super image by default

Usage examples:

Bash:

adb shell
su
cd /data/local/tmp/sysrw_1.33
chmod +x ./sysrw

#  Run program with default settings [RECOMMENDED]
./sysrw

# Specify existing super image as input [OPTIONAL]
./sysrw in=./img/super_original.img

# Specify patched super image output file path [OPTIONAL]
./sysrw out=./img/super_patched_new.img

# Specify the extra free space (in megabytes) to be added to each sub-partition of super.img [OPTIONAL]
./sysrw size=15

# Specify whether or not the patched super image should be output in raw file format [OPTIONAL]
./sysrw -r

# EXPERT EXAMPLE (Warning! This command could potentially corrupt your system. Only use at your own risk in recovery mode!)
./sysrw in=img/super_original.bin out=`realpath /dev/block/by-name/super` -r

Uninstallation:

To free up space and keep script as well as r/w capability you can simply delete /img subfolder at /data/local/tmp/sysrw_*VERSION*/img
To delete script and keep r/w capability you can simply delete whole script folder at /data/local/tmp/sysrw_*VERSION*
To undo all changes performed by the script you can simply reflash original stock read-only super image and re-enable dm-verity and verification either through adb/fastboot or with the included avbctl binary.

Troubleshooting:

If you can't get this script to work on your device check out the brand new sophisticated superrepack tool by @munjeni

ERROR 73: Troubleshooting repair script instructions

@harpreet.s slot switching workaround

If you get any errors from the update-binary in your custom recovery during installation of the flashable .zip then please send me this log file /tmp/recovery.log

and a screenshot of your error. Thanks!

Make sure the script folder was correctly extracted to:

/data/local/tmp/sysrw_*VERSION*

If you can't run the script try making the file executable like this: chmod +x ./sysrw

If you still can't get it to work run which sh in your shell and replace the shebang in the first line of the script with the output of that command. Don't remove the first two #! symbols though. Then save the file and try again.

Make sure you've got full read / write access to the /data/local/tmp directory and that the containing files are not encrypted in custom recovery!

If you get a bootloop after successfully creating and flashing super_patched.bin then that's probably because you didn't properly disable your dm-verity and verification.

To undo any bootloop simply re-flash original stock read-only super image and re-enable dm-verity and verification with the included avbctl binary or through adb/fastboot. Those are the only changes performed by the script. If you have any more questions just ask in this thread. Good luck!

About:

I did not come up with all this by myself. After searching for a solution for countless days without success, going even as far as learning hex editing - I accidentally came across a couple of very interesting threads burried deep inside the new forum interface where this method has been described by various rw enthousiasts (links can be found in the credits section below). Therefore most credit goes to these rw enthousiasts. I'm only the amateur who put it all together into a compact script so that everybody can enjoy an Android system that's read/write-able again. Just like it used to be in Android 9 or earlier. Before these annoying 'shared_blocks' and 'EROFS' read-only features were implemented.

Credits:

Huge thanks to @Brepro1 for allowing me to use his awesome tutorial and make it into a script. Without your tutorial guiding me I couldn't have created this script.

Huge thanks to @Kolibass for allowing me to use his partition tools for Android. Without your tools this script would not work on the Android platform!

Big thanks @munjeni for allowing me to use his amazing superunpack V1 tool in the initial version. It helped me to understand how these super images work.

Thanks @AndyYan your great tutorial also helped me a lot for automating the script especially the lpdump part.

Thanks @bynarie for making available his otatools package! A part of it was bundled with the initial version which helped me to create this universal version. It's still part of the troubleshooting repair script to fix error 73.

Thanks @HemanthJabalpuri for assisting me in optimizing the underlying algorithm!

If the script works on your device please send me your log files from this folder:
/data/local/tmp/systemrw_1.32/log/

And please write your phone model - Android version - firmware version

Then I can add you to the list of successful devices and it will be helpful for further development. Thank you!

walid77dz · Mar 14, 2021

doesn't work for me!

lebigmac · Mar 14, 2021

You're supposed to run this on the phone

This universal version is different from the previous Linux only version!
Please follow the instructions in the first post or in the comment section of the script itself!

It looks like I'll have to make a flashable zip out of this. Please give me a day or two to learn more about flashable zip's!
I just wanted to release it as soon as possible because I know many people were waiting for the new universal version

you mean terminal of twrp?

Frxhb · Mar 14, 2021

Thanks for your hard work. So I just need to copy the file to my storage and run it with TWRP ( I use orangefox) and nothing more?

lebigmac · Mar 14, 2021

Manual installation:

Extract BUNDLE.zip
Extract flashable.zip
Copy systemrw_1.32 folder into /data/local/tmp/
It should look like this:
/data/local/tmp/systemrw_1.32

Please keep in mind I have not tested this in orangefox but only in twrp so you will be the first person to do so!
Is orangefox an engineer build like twrp? You can check this by doing

Code:

getprop ro.build.type

Frxhb · Mar 14, 2021

when I run " getprop ro.build.type" the answer is "eng"

yes but the makesysrw_1.15 folder containing the script should go into /data/local/tmp/
so it should look like this:
/data/local/tmp/makesysrw_1.15

Also if you have orangefox you can simply replace the TWRP check at line #303 with this:

Code:

if ( whoami>/dev/null ); then

Please keep in mind I have not tested this in orangefox but only in twrp so you will be the first person to do so!
If orangefox is anything like twrp it should work! Is orangefox an engineer build like twrp?

You've got to be kidding me!
Thanks for your feedback uvzen. I think you were the first one to try it. Congratulations

Can you please tell me do you have a super partition on your device? What Android version?
And how did you like the flashing process? Was it smooth and fast?
Thanks to a suggestion by user @Kolibass the flashing is now super fast in this new version!

Device: Xiaomi Redmi Note 9 Pro joyeuse Android 10 MIUI 12.0.1
I have a super partition and the process took about 5 minutes

So is your system read-write now? Did you use any special arguments when calling the script such as size=100 to give extra free space to your partitions? That's useful so you can copy stuff to system. Otherwise you can only delete stuff...

I used ./makesysrw.sh size=300 but that's not enough and now I will try with size=1000

lebigmac · Mar 14, 2021

1 GB (1024 MB) is probably too much

Did you try copy stuff into /system yet to see if it's read write?
In your favorite root file manager you can click the remount as R/W button on top.
You can also try mounting your partition(s) as read/write manually like this:

uvzen · Mar 14, 2021

I mean 300MB is not enough for me xD

Please post an instructional video

walid77dz · Mar 14, 2021

@walid77dz did you try to boot into android, set a PIN code and then reboot to TWRP and decrypt everything by entering your PIN code?
