**1. Prepare TFTP server**

Set a static IP on the ethernet interface of your computer (e.g. default: ip `192.168.1.2`, gateway `192.168.1.1`).

Download the initramfs image and host it with the TFTP server.

**2. Interrupt boot**

Attach UART and power on the router. When the boot menu appears, select **Failsafe Mode**,
then press `Ctrl-C` to interrupt and enter the U-Boot prompt.

**3. Load and run initramfs image**
```sh
setenv ipaddr 192.168.1.1
setenv serverip 192.168.1.2
tftpboot 0x46000000 openwrt-mediatek-filogic-jiorouter_ax6000-jidu6101-initramfs-kernel.bin
fdt addr $(fdtcontroladdr)
fdt rm /signature
bootm
```

**4. Flash sysupgrade image**

Place the sysupgrade image in `/tmp`, then run:
```sh
sysupgrade /tmp/openwrt-mediatek-filogic-jiorouter_ax6000-jidu6101-squashfs-sysupgrade.bin
```
Alternatively, use the sysupgrade option in LuCI.

Note:
- The raw MTD u-boot-env partition is only used for MAC address storage, while the active U-Boot environment is stored in the UBI volume.
- These devices ship with secure boot enabled and stock U-Boot only accepts vendor-signed FIT images.
- BL2/FIP cannot be replaced, so the stock signature verification path cannot be disabled directly.
- Setting ipaddr='' forces U-Boot to exit the web failsafe path and continue into autoboot.
- The custom bootcmd loads OpenWrt from the UBI volume and removes the /signature node before bootm, allowing unsigned OpenWrt FIT images to boot.
- Stock U-Boot expects its environment in a UBI volume named u-boot-env, so it is created during initial setup.
