| − | === How to completely erase the Radxa Zero eMMC === | + | === How to erase eMMC === |
| | | | |
| − | This guide describes how to completely erase Radxa Zero eMMC. Since we are running different image, Android or multiple Linux distribution on the Zero, these images uses different bootloader version or boot sequence. It's better to erase the eMMC completely and leave a clean environment before installing new images to eMMC. | + | This guide describes how to erase Radxa Zero series eMMC for installing a new system. Beware that this is not a secure erase, and only the bootloader and the partition header are wiped. |
| | + | |
| | + | For more detailed guide on wiping eMMC (or if this fails), please refer to [[Zero/install/Boot_Troubleshooting | Boot Troubleshooting]] page. |

This guide describes how to erase Radxa Zero series eMMC for installing a new system. Beware that this is not a secure erase, and only the bootloader and the partition header are wiped.
Once your computer detects a new USB storage device, your eMMC will be wiped and you can flash to this newly found USB device.
