• ONLY IF U-BOOT HAS BEEN UPDATED! Check the u-boot version
with command version at the u-boot prompt, and flash the u-boot ONLY
if the u-boot version at the dev zone is newer. This step is critical and
could brick the unit, so make sure of inserting the commands correctly.

The user can create a customized UBIFS, based on the rootfs available in the
dev zone, owa4x FS tree. After decompressing it in the PC and make the
desired changes to it, mkfs.ubifs and ubinize commands may be used to create
the image. The resulting image will have only one UBI volume storing UBIFS
file-system.
• Commands to create a FS <= 1.0.8 and HW < R2
$ sudo mkfs.ubifs -F -q -r rootfs -m 4096 -e 520192 -c 1980 -o
ubifs.img
$ ubinize -o ubi.img -m 4096 -p 512KiB -s 1024 ubinize.cfg
where ubinize.cfg contains:
[ubifs]
