Gain SSH access:
1. Login into web interface, and download the configuration.
2. Enter fakeroot, decompress the configuration:
tar -zxf cfg_export_config_file.conf
3. Edit 'etc/config/dropbear', set 'enable' to '1'.
4. Edit 'etc/shadow', update (remove) root password:
'root::19523:0:99999:7:::'
5. Repack 'etc' directory:
tar -zcf cfg_export_config_file.conf etc/
* If you find an error about 'etc/wireless/mediatek/DBDC_card0.dat',
just ignore it.
6. Upload new configuration via web interface, now you can SSH to RAX3000M.
Check stroage type:
Check the label on the back of the device:
"CH EC CMIIT ID: xxxx" is eMMC version
"CH CMIIT ID: xxxx" is NAND version
eMMC Flash instructions:
1. SSH to RAX3000M, and backup everything, especially 'factory' part.
('data' partition can be ignored, it's useless.)
2. Write new GPT table:
dd if=openwrt-mediatek-filogic-cmcc_rax3000m-emmc-gpt.bin of=/dev/mmcblk0 bs=512 seek=0 count=34 conv=fsync
3. Erase and write new BL2:
echo 0 > /sys/block/mmcblk0boot0/force_ro
dd if=/dev/zero of=/dev/mmcblk0boot0 bs=512 count=8192 conv=fsync
dd if=openwrt-mediatek-filogic-cmcc_rax3000m-emmc-preloader.bin of=/dev/mmcblk0boot0 bs=512 conv=fsync
4. Erase and write new FIP:
dd if=/dev/zero of=/dev/mmcblk0 bs=512 seek=13312 count=8192 conv=fsync
dd if=openwrt-mediatek-filogic-cmcc_rax3000m-emmc-bl31-uboot.fip of=/dev/mmcblk0 bs=512 seek=13312 conv=fsync
5. Set static IP on your PC:
IP 192.168.1.254, GW 192.168.1.1
6. Serve OpenWrt initramfs image using TFTP server.
7. Cut off the power and re-engage, wait for TFTP recovery to complete.
8. After OpenWrt has booted, perform sysupgrade.
9. Additionally, if you want to have eMMC recovery boot feature:
(Don't worry! You will always have TFTP recovery boot feature.)
dd if=openwrt-mediatek-filogic-cmcc_rax3000m-initramfs-recovery.itb of=/dev/mmcblk0p4 bs=512 conv=fsync
NAND Flash instructions:
1. SSH to RAX3000M, and backup everything, especially 'Factory' part.
2. Erase and write new BL2:
mtd erase BL2
mtd write openwrt-mediatek-filogic-cmcc_rax3000m-nand-preloader.bin BL2
3. Erase and write new FIP:
mtd erase FIP
mtd write openwrt-mediatek-filogic-cmcc_rax3000m-nand-bl31-uboot.fip FIP
4. Set static IP on your PC:
IP 192.168.1.254, GW 192.168.1.1
5. Serve OpenWrt initramfs image using TFTP server.
6. Cut off the power and re-engage, wait for TFTP recovery to complete.
7. After OpenWrt has booted, erase UBI volumes:
ubidetach -p /dev/mtd0
ubiformat -y /dev/mtd0
ubiattach -p /dev/mtd0
8. Create new ubootenv volumes:
ubimkvol /dev/ubi0 -n 0 -N ubootenv -s 128KiB
ubimkvol /dev/ubi0 -n 1 -N ubootenv2 -s 128KiB
9. Additionally, if you want to have NAND recovery boot feature:
(Don't worry! You will always have TFTP recovery boot feature.)
ubimkvol /dev/ubi0 -n 2 -N recovery -s 20MiB
ubiupdatevol /dev/ubi0_2 openwrt-mediatek-filogic-cmcc_rax3000m-initramfs-recovery.itb
10. Perform sysupgrade.

Installation
------------
1. Connect to the device using serial console.
2. Interrupt the Autoboot process when promted by sending '0' twice.
3. Serve the OpenWrt initramfs image using TFTP at 192.168.1.66. Name
the image "predator.bin" and conenct the TFTP server to the routers
LAN port.
4. Configure U-Boot to allow loading unsigned images from MMC
$ setenv bootcmd 'mmc read 0x40000000 0x00004400 0x0010000;
fdt addr $(fdtcontroladdr); fdt rm /signature; bootm 0x40000000';
saveenv
5. Transfer the image from U-Boot
$ setenv serverip 192.168.1.66; setenv ipaddr 192.168.1.1;
tftpboot 0x46000000 predator.bin; fdt addr $(fdtcontroladdr);
fdt rm /signature; bootm
6. Wait for OpenWrt to boot
7. Transfer the OpenWrt sysupgrade image to the router using scp.
8. Install OpenWrt using sysupgrade.

Installation
------------
1. Download the OpenWrt initramfs image. Copy the image to a TFTP server
reachable at 192.168.1.66/24. Rename the image to tufax4200.bin.
2. Connect the TFTP server to the AX4200. Conect to the serial console,
interrupt the autoboot process by pressing '4' when prompted.
3. Download & Boot the OpenWrt initramfs image.
$ setenv ipaddr 192.168.1.1
$ setenv serverip 192.168.1.66
$ tftpboot 0x46000000 tufax4200.bin
$ bootm 0x46000000
4. Wait for OpenWrt to boot. Transfer the sysupgrade image to the device
using scp and install using sysupgrade.
$ sysupgrade -n <path-to-sysupgrade.bin>
Missing features
----------------
- The LAN port LEDs are driven by the switch but OpenWrt does not
correctly configure the output.
