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.
