1. 从这里下载并解压文件。
2. 从官方网站下载最新固件，并将其重命名为“recovery.bin”。注意：必须将其放在与 Tftpd 工具相同的文件夹中。
3. 关闭路由器电源。拔下电源适配器或按下电源按钮。
4. 使用以太网线将电脑连接到路由器的 LAN 端口。

6. 运行“ tftp32.exe ”。
7. 在命令行运行“ netsh advfirewall set allprofiles state off ”命令来禁用Windows防火墙，否则TFTP连接将被阻止。或者，您也可以在计算机的控制面板中禁用防火墙，如下所示。
8. 按住“重置”按钮/孔。在路由器通电之前以及TFTP开始下载固件之前，不要松开“重置”按钮/孔。
9. 打开路由器电源。
10. 当所有指示灯快速闪烁，或者 tftp 开始下载固件时，您可以松开“重置”按钮/孔。
11. 当指示灯缓慢闪烁时，升级完成。

TR3000 256MB V1.0 — bricked after flashing intermediate firmware
Hello Cudy Support,
I have a Cudy TR3000 256MB Flash V1.0 router.
Serial number: s0001825262604247
What happened:
I updated the router to the official firmware m_upgrade_TR3000_256MB_Flash-R103-2.5.21-20260708.
After that, I downloaded the intermediate firmware DTS_and_intermediate_firmware_b766f42b-5e1c-4ad5-85b2-53990a85a956 from the TR3000-256MB 1.0 download page.
I flashed this intermediate firmware through the web interface.
After the flash, the router does not boot. It is bricked.
What I need:
The correct TFTP recovery file (recovery.bin) for my specific device.
Step-by-step TFTP recovery instructions for TR3000 256MB V1.0.
Confirmation of which flash chip is installed in my unit (F50L1G41LB or F50L1G41LC).
The correct intermediate firmware for my device revision to install OpenWrt, if my unit has the new flash chip.
Please help me recover the router.
Thank you.
Hello again, I have already written a comment here in search of a solution to my problem. I have a cudy tr30 router model, I installed the openwrt firmware on it according to the YouTube guide and after the power was turned off, the firmware stopped loading, I tried everything except using UART, today I’ll probably try to figure it out with chat gpt, but if you have another easier way to get the cudy tr30 firmware back, then I I would be very grateful.
@Уважаемый Евгений,
Спасибо за отзыв.
“В модели WR300 необходимо не зажимать кнопку, а при подаче питания несколько раз нажать.”
@Уважаемый Михаил,
Пожалуйста, внимательно проверьте шаги. При восстановлении необходимо подключить компьютер к порту LAN на TR3000.
