Burn .IMG to another MicroSD Card without root Long story, I have a Raspberry Pi 3 Model B and the only device I own that can write a Raspbian image to MicroSD is my Android phone. I have copied the image from my laptop to my MicroSD, but I am puzzled as to how I can write the IMG to the MicroSD, as rooting will void my warranty. MicroSD is necessary since the Raspberry Pi will not boot from USB.
Copy the IMG file to the internal storage
Download EtchDroid [NO ROOT] - Write ISOs and DMGs to USB from Play Store
Select raw image or ISO (do these steps after the SD card has been plugged in)
Select the IMG file and the SD card
Wait until it completes the progress (it is possible to check the progress in the taskbar/notification)
Done
