1. Download and unzip the file from here.
2. Download the latest firmware from the official website and rename it to 'recovery.bin'. Note: You must put it in the same file of Tftpd tools.
3. Power off your Router. Unplug the power adapter or press the POWER button.
4. Connect your computer the Router's LAN port with an Ethernet cable.
Note: Only one model is an exception: the TR1200. The WAN port must be connected during firmware recovery. All other models use the LAN port.
5. Configure your computer's IP address to be '192.168.1.88' manually.
6. Run 'tftp32.exe'.
7. Run 'netsh advfirewall set allprofiles state off' in the command line to disable Windows firewall, otherwise tftp will be blocked. Or you can disable the firewall on the Control Panel of your computer. As shown below.
8. Press the 'Reset' button/hole and hold it. Before the Router is powered on and before tftp start to download the firmware, don't release the 'Reset' button/hole.
9. Power on the Router.
10. When the Lights are all flashing fast, or when tftp start to download the firmware, you can release the 'Reset' button/hole.
11. When the light flashes slowly, the upgrade is complete.
12. Please recover your computer's IP address to be dynamic IP.
13. Done.

m_upgrade_TR3000-R47-2.4.22-20251113-125907..这个就是使用的2.4.22版本，同时也尝试了2.4.21（m_upgrade_TR3000_256MB_Flash-R103..）仅给256MB用的版本，情况和之前是一样的
“TR3000 256M 没有2.4.22固件版本，最新的是2.4.21。所以你应该是下载了TR3000 128MB的版本固件。请重新下载TR3000 256MB的固件进行恢复。”
“TR3000 256mb sn2550，recovery.bin文件用的2.4.22原版固件，恢复出厂遇到问题：
1. 到TFPT刷写完毕后，指示灯从红白快速闪烁 – 短时间白灯 – 一直持续慢速红白闪烁
2. DHCP失效，不分配路由IP。无法登入192.168.10.1。”
