This allows us to use the full size of nand,
which extends ubi size from 64Mb to 122.25Mb.
If you are at factory firmware, please refer
to [PR](https://github.com/openwrt/openwrt/pull/21141)
to boot into OpenWrt first.
1. Log in to the device and backup all the partitions,
especially unique `Factory` and `bdata` partitions
from System -> Backup / Flash Firmware -> Save mtdblock contents.
2. Install kmod-mtd-rw to unlock mtd partitions for writing:
```bash
apk update && apk add kmod-mtd-rw && insmod mtd-rw i_want_a_brick=1
```
3. Write new OpenWrt (U-Boot Layout) `BL2` and `FIP`:
```bash
mtd write openwrt-mediatek-filogic-cudy_wbr3000uax-v1-ubootmod-preloader.bin BL2
mtd write openwrt-mediatek-filogic-cudy_wbr3000uax-v1-ubootmod-bl31-uboot.fip FIP
```
4. Set static IP on your PC: `192.168.1.254`, gateway `192.168.1.1`
5. Serve openwrt-mediatek-filogic-cudy_wbr3000uax-v1-ubootmod-initramfs-recovery.itb
using TFTP server.
6. Connect Router LAN with PC LAN.
7. Cut off the power and re-engage, wait for TFTP recovery to complete.
8. After OpenWrt initramfs recovery has booted,
clean `/dev/mtd5` ubi partition to utilize maximum of free space & create ubootenvs:
```bash
ubidetach -p /dev/mtd5; ubiformat /dev/mtd5 -y; ubiattach -p /dev/mtd5
ubimkvol /dev/ubi0 -n 0 -N ubootenv -s 128KiB
ubimkvol /dev/ubi0 -n 1 -N ubootenv2 -s 128KiB
```
4. Perform sysupgrade.
