I made a live USB for Ubuntu 17.04 using MKUSB from this tutorial here: How to make a persistent live Ubuntu USB with more than 4GB

But I am unable to get the persistent storage to work for me. The live USB has been created successfully and it boots perfectly fine but it looses all my files on reboot.

I tried adding the word "persistent" to every line with "linux" in the boot.cfg and loopback.cfg files.

Edit: I used a 16GB USB to make the Live USB. Though I found out one thing, if while booting I edit the boot commands from grub to add a 'persistent' keyword, persistence works just fine. If I do not, it doesn't. Hence I have to manually edit the command everytime I have to boot into Ubuntu Live.

Here's what my loopback.cfg file looks like before I edit for persistence.

menuentry "Try Ubuntu without installing" {
    set gfxpayload=keep
    linux   /casper/vmlinuz.efi  file=/cdrom/preseed/ubuntu.seed boot=casper iso-scan/filename=${iso_path} quiet splash persistent --
    initrd  /casper/initrd.lz
}
menuentry "Install Ubuntu" {
    linux   /casper/vmlinuz.efi  file=/cdrom/preseed/ubuntu.seed boot=casper only-ubiquity iso-scan/filename=${iso_path} quiet splash persistent --
    initrd  /casper/initrd.lz
}
menuentry "Check disc for defects" {
    linux   /casper/vmlinuz.efi  boot=casper integrity-check iso-scan/filename=${iso_path} quiet splash ---
    initrd  /casper/initrd.lz
}
menuentry "Test memory" {
    linux16 /install/mt86plus
}

Here's what I edit to make persistence work.

menuentry "Try Ubuntu without installing" {
    set gfxpayload=keep
    linux   /casper/vmlinuz.efi  file=/cdrom/preseed/ubuntu.seed boot=casper iso-scan/filename=${iso_path} quiet splash persistent --
    initrd  /casper/initrd.lz
}
menuentry "Install Ubuntu" {
    linux   /casper/vmlinuz.efi  file=/cdrom/preseed/ubuntu.seed boot=casper only-ubiquity iso-scan/filename=${iso_path} quiet splash persistent --
    initrd  /casper/initrd.lz
}
menuentry "Check disc for defects" {
    linux   /casper/vmlinuz.efi  boot=casper integrity-check iso-scan/filename=${iso_path} quiet splash persistent --
    initrd  /casper/initrd.lz
}
menuentry "Test memory" {
    linux16 /install/mt86plus
}

I have to manually edit it everytime I boot because the changes I make to the file from Windows revert back to original.

    I will try to help you :-) But I need more information about what you have and what you did. 1) Which of the answers in that thread did you use?; 2) Please describe the computer (at least brand name and model); 3) Please edit your original question and add the output of the following command lines, when booted from the live drive, df -h ; sudo lsblk -f ; sudo lsblk -m ; sudo parted -ls ; uname -a ; lsb_release -a – sudodus Jun 30 '17 at 07:11
