2. Turn Phoenix OS bootable USB into Persistence

The fundamental theory is you boot any operating system from a USB, shut it down. Next boot apparently a fresh-install of any given operating system, erasing everything as soon as you shut it down.

To overcome this issue, a simple approach is to create data.img file and save it to Phoenix OS/ROC USB root directory. Easy peasy right, lets get started.

Get this tool, extract and fire it on your computer. Select a new file, slider all the across to 4090MB and go with an ext3 file type. You’re done, now just stair the screen for about 10 minutes, litrelly it takes time.

  1. Download Win image maker tool, extract it on your desktop.
  2. Open the folder and run TopoResize file.
  3. Click create new, and save the file as data.img and allot desired size.

Select partition type ext3 and select root directory of phoenix os. The maximum size you can allot is 4GB (as per FAT32, ext3 largest file size limitation). Click ok to start creating the data file.

Root directory: where system.img , system.sfs etc files are present)

That’s it, it might take couple of minutes to half an hour and during process it may show as not responding. But give it time, and once finished the app windows will be closed. Now you can use Phoenix OS from USB and it will save everything you do.

Application of the process can be playing games, so you don’t have to install the game each time you want to play. It can go annoying when you have to login to your google account to access Play store, but with this approach you have to do everything one time and can start from where you left.

Read all the possible scenarios where things could go wrong. First thing is do not format USB as NTFS partition, especially with particular GPT and MBR setting. Try to create FAT32 type with MBR/GPT. (In Rufus application)

Second, do not install the OS from USB to hard drive, it will replace the Windows bootloader and replaces it with GRUB2. If that’s what you want, use the Installer version of Phoenix OS.

Never try to modify the data.img or other files of USB drive, it could malfunction the OS and not to mention PUBG mobile takes actions against data manipulation.

3. Make changes to the GRUB file.

Two location are: USB/boot/efi and other in root directoy.

You need to open the .cfg file in something we call “text editor” use notepad++. You won’t regreat.

Make sure the code look like the below screenshot.
