- 0x0000065a0000-0x000007580000 : "Custom"
- The original partition-Ubi partition-Ubi1 is an AB dual system, and Openwrt only uses Ubi. So flash requires modifying the uboot variable `boot_from=ubi` to ensure that it only starts from Ubi.
- The Product and Custom partitions are original and only exist to align with the original layout; they are not used by OpenWrt.
- id: 0, kernel
- id: 1, rootfs
- id: 2, rootfs_data
- **USB-to-TTL Serial Adapter** (e.g., CH340 or CP2102).
- **Dupont Wires** (male-to-male, 3 wires).
- **PC/Laptop** with a serial communication tool.
- Screwdriver (to open the router case).
1. **OpenWrt Firmware**:
- Download the appropriate `wr3000k-<build_time>-mediatek-filogic-tenbay_wr3000k-squashfs-sysupgrade.bin` firmware file for your router from the [OpenWrt website](https://openwrt.org/).
2. **Serial Communication Tool**:
- Windows: PuTTY, Tera Term.
- Linux/Mac: Minicom, screen.
3. (Optional) **TFTP Server**:
- Install a TFTP server like Tftpd64 or tftp-hpa.
---
1. Open the router casing and locate the **TX, RX, and GND** pins.
2. Connect the router pins to the USB-to-TTL adapter as follows:
- **TX (router)** → **RX (adapter)**
- **RX (router)** → **TX (adapter)**
- **GND (router)** → **GND (adapter)**
3. Do **not** connect the VCC pin to avoid damage.
- **Baud rate**: 115200
- **Data bits**: 8
- **Stop bits**: 1
- **Parity**: None
- **Flow control**: None
---
1. Power on the router and observe the serial terminal output.
2. When prompted (e.g., `Hit any key to stop autoboot: 3`), press the '/' key quickly to interrupt the boot process.
3. You will see the U-Boot Boot Menu:
```plaintext
*** U-Boot Boot Menu ***
1. Factory mode
2. Startup system (Default)
3. Upgrade firmware
4. Upgrade ATF BL2
5. Upgrade ATF FIP
6. Upgrade single image
7. Load image
0. U-Boot console
Press UP/DOWN to move, ENTER to select, ESC/CTRL+C to quit
```
4. Select Option 0 by typing 0 and pressing Enter.
5. Input into
```plaintext
MT7981> setenv boot_from ubi
MT7981> saveenv
Saving Environment to MTD... Erasing on MTD device 'nmbm0'... OK
Writing to MTD device 'nmbm0'... OK
OK
MT7981> printenv
baudrate=115200
boot_from=ubi
...
```
the above indicates system will start from *ubi*.
and then type
```plaintext
MT7981> reset
```
will boot from *ubi*
1. Power on the router and observe the serial terminal output.
2. When prompted (e.g., `Hit any key to stop autoboot: 3`), press the '/' key quickly to interrupt the boot process.
3. You will see the U-Boot Boot Menu:
```plaintext
*** U-Boot Boot Menu ***
1. Factory mode
2. Startup system (Default)
3. Upgrade firmware
4. Upgrade ATF BL2
5. Upgrade ATF FIP
6. Upgrade single image
7. Load image
0. U-Boot console
Press UP/DOWN to move, ENTER to select, ESC/CTRL+C to quit
```
4. Choose Option 3: Upgrade Firmware
Enter Upgrade Mode
Select Option 3 by typing 3 and pressing Enter.
Upgrade Methods
You will be prompted to choose between:
```plaintext
*** Upgrading Firmware ***
Run image after upgrading? (Y/n): y
Available load methods:
0 - TFTP client (Default)
1 - Xmodem
2 - Ymodem
3 - Kermit
4 - S-Record
5 - RAM
Select (enter for default): 0
Input U-Boot's IP address: 192.168.1.1
Input TFTP server's IP address: 192.168.1.10
Input IP netmask: 255.255.255.0
Input file name: wr3000k-<build_time>-mediatek-filogic-tenbay_wr3000k-squashfs-sysupgrade.bin
```
Type Enter to proceed. The router will erase the old firmware and write the new one.
