2. Using (Termux + WSL2)

# No Computer needed.

DISABLE PHANTOM PROCESS KILLER In Android 12 & 13

Disable Phantom Process Killer in android 12 & 13. It’s a background process limiter that kills the app processes using excessive CPU or system resources.

## Set of the command for Termux.

pkg install git

*Where are data of termux.?

/data/data/com.termux/files

termux-setup-storage

termux-change-repo

pkg update

pkg install android-tools e2fsprogs

pkg install tsu

pkg install mount-utils or pkg install termux-tools

Why Read Only?

Most devices have small system partition which might even be less than 3GB. To tackle this we enable shared blocks through which we can reduce the image's size to a huge extent.

Requirements

1. A Linux pc/android phone (WSL/Debain or ubuntu based distributions/Arch based distributions etc.)

2. Downloaded GSI which is read only

3. A bit of linux knowledge

setup for termux users (ignore if using linux)

1. Run the below command to setup storage. grant the storage popup if shown.

termux-setup-storage

2. Run the below commands to install prerequisites.

pkg update

pkg install android-tools e2fsprogs

Now continue with the guide as usual.

1. Open a shell in Termux app.

ls
#Output: storage

cd storage

2. Uncompress the gsi from .xz file and copy it to our new folder

Rename gsi's file name to system.img

Is

#Output
dcim external-1 music shared downloads movies pictures system.img

3. First we resize the image to 4GB to fit our new unshared blocks. if the image is near to 4GB or higher then do 6GB etc. Dont worry we'll reduce it back later

resize2fs system.img 5G

4. Now we finally unshare the blocks!

e2fsck -E unshare_blocks system.img

If it asks you to run a cmd and errors without it. and file size doesnt change then run the cmd and run the above cmd again.

There! the same file you copied is now read/write!

5. We need to reduce the file size to the minimum that it can be.

Run the following command to resize it to the minimum that it can be.

resize2fs -M system.img

Now enjoy your read/write rom. go flash it the image. (dirty flashing over existing installation will work)

We will copy "system.img" from tab device to mod in WSL2.(Computer)

cp system.img downloads

Connect Tab device with Computer by USB cable.

Next transfer image file "system.img" to WSL2
