Some devices have limited RAM size and not enough for some large installation images – in this case you need to use additional SD/USB removable storage to temporarily store the installation image. All steps are the same, just:

1. plug removable storage (SD / USB)
2. open Main menu
3. go to Advanced
4. select Mount dumps storage SD/USB
   1. if needed, format it first via Format OOWOW storage SD
5. back to Main menu
6. select Write image to eMMC
7. select downloads
8. press Refresh images list
9. select image
10. download / install
11. unplug removable storage
12. reboot
