Modifying any of these settings may render your Relio R9 unbootable.
When upgrading an existing OS runtime stored in the NAND Flash, it is necessary to first erase the NAND
Flash of a pre-programmed unit. This is accomplished through the “Image flash menu” (‘n’ key) in Eboot.
The flash menu has an option to “Erase all sectors” of the NAND Flash (‘1’ key). (See Figure 29.)
Figure 29-
Eboot Image Flash Menu
The “Erase all sectors” option in Eboot will erase the entire NAND Flash, so be sure to back up any
data you wish to save before attempting to erase the device.
