Format ubi and create new ubootenv volume: Or OpenWrt U-Boot may boot into NAND recovery or tftp recovery.ħ. Run the following cmd to clean all pending crash dumps in pstore, Insmod /lib/modules/$(uname -r)/mtd-rw.ko i_want_a_brick=1Ħ. Select your OpenWrt release version and kernel version accordingly. Or, download kmod-mtd-rw.ipk from OpenWrt server and install it manually If you're building your own image, remember to add kmod-mtd-rw module in Kernel modules > Other modules The kmod-mtd-rw is from the feeds, it is not packed in initramfs-factory by default. Load kmod-mtd-rw to temporarily make the bootloader partitions writable. It'll boot into initramfs, check mtd partion info.ĥ.
Run the following cmd to boot into an initramfs with the new OpenWrt U-Boot layout that expand ubi partion to the end of flash: Then backup your configurations, since ubiformat for entire mtd device is required to create new ubootenv volume for OpenWrt U-Boot.ģ. Backup BL2, Nvram, Bdata, Factory and FIP in case you break something or you want to go back to stock firmware one day.Īnd save all whose bin files to somewhere safe. Your device should already running OpenWrt (stock layout) as per above instructionsĢ. If you want to move to ubootmod layout, keep reading.ġ. If you want to stay in this layout, you're done.
