如何将 Cudy 路由器从 OpenWRT 固件恢复为 Cudy 官方固件?

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。

注意:只有一款型号例外:TR1200。固件恢复期间必须连接 WAN 端口。其他所有型号均使用 LAN 端口。

5. 手动将计算机的 IP 地址配置为“192.168.1.88”。

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。

12. 请将您电脑的 IP 地址恢复为动态 IP。

13. 完成。

@Уважаемый Павел,
Какая прошивка у вашего Cudy TR30 (TR3000)? Это последняя версия прошивки 2.4.7? Если нет, пожалуйста, сначала обновите прошивку. Затем проверьте еще раз.

“Здравствуйте! При подключении к Cudy TR30 (TR3000) LTE модема, нет соединения. В настройках Cudy USB соединение неактивно. Что можно сделать?”

@Dear Alan,
So, why do you think it is the 256MB version. The 256MB version is only available for sell in China. The words on the label are in Chinese language, please have a check.

“Regarding the previous issue (failure to recover TR3000-256MB), I was finally able to revive it from being bricked using TTL. My router itself has no any hardware faults. I discovered that the NAND chip’s memory size differs from what is indicated on the box or label. This mismatch led to flashing the wrong version, causing it to become bricked and continuously reboot.

The chip inside is an ESMT F50L1G41LB, which can be broken down as follows:

F – Manufacturer: ESMT 50 – Product Collection L – Low Voltage (DDR3L) 1G – Density: 1Gb (Single Capacity) 41 – Organizational Structure: x16 (16-bit wide) LB – Packages and Versions
The capacity of a single unit is calculated as follows:
1Gb ÷ 8 bits/byte = 128MB
I hope you all don’t have to deal with the same issue I experienced. I’ve reached out to sales@cudy.com but haven’t received a response yet."

@Уважаемый Павел,
Пожалуйста, следуйте этой инструкции шаг за шагом. Если это не поможет, попробуйте выполнить эту операцию на другом компьютере.

“Здравствуйте! После прошивки роутера Cudy TR30 (TR3000) на OpenWRT решил прошить на заводскую прошивку и видимо бэкап не прошился. Теперь роутер не загружается и не заходит в web панель управления. Как можно это исправить?”
