https://youtu.be/gOMUqic2Fwk

This instuction for (64GB version)!

WARNING! YOU CAN BRICK YOUR PHONE! USE IT AT YOUR OWN RISK!

PARTITIONING

For partitioning we need to Boot the phone from TWRP recovery

So first of all we need to copy parted for android (https://pwdx.lanzoux.com/iUgSEmkrlmh) to the phone's sbin directory

# host
adb push parted /sdcard/
adb shell

# phone
cp /sdcard/parted /sbin/ && chmod 755 /sbin/parted

Stock partitions should look like this

Next, we need to remove userdata partition and create new partitions

/sbin/parted /dev/block/sda
rm 21
mkpart esp fat32 1611MB 1900MB
mkpart userdata ext4 1900MB 25GB
mkpart win ntfs 25GB 50GB 
mkpart lnx ext4 50GB 58.1GB
mkpart pe fat32 58.1GB 59.1GB
set 21 esp on

Modified partitions should look like this

Next, we need to reboot the phone to TWRP again

Format created partions

mkfs.fat -F32 -s1 /dev/block/by-name/esp
mkfs.ntfs -f /dev/block/by-name/win
mke2fs -t ext4 /dev/block/by-name/userdata
mke2fs -t ext4 /dev/block/by-name/lnx
mkfs.fat -F32 -s1 /dev/block/by-name/pe

Reboot
