How to recover the firmware of RG-EW3200GX PRO

Hello,
I installed the latest firmware for my router "RG-EW3200GX PRO Wireless Routers EW_3.0(1)B11P219 firmware.zip" with "EW_3.0(1)B11P219_EW3200GXI_10182113.tar.gz" inside, but this caused my router to no longer function properly.
The internet via LAN cable was working, but the wifi was down.
I went to 192.168.110.1 website to fix it, but they said password was wrong (I typed the correct password), so I pressed the reset button on the router. Now, even the LAN cable is not working, and there is no wifi shown.
When I try turning off & on the router, it blinks blue very quickly, steady light for a second, then keeps on blinking.


I tried the guide on https://community.ruijienetworks.com/forum.php?mod=viewthread&tid=5990&extra=page%3D1 but the TFTP transfer does not start, even after rebooting 11 times.

Any help would be appreciated

Dear sir

Could you help connect your pc to the EW lan port, and try to login to the EW router via IP 192.168.110.1 to check whether can reach? If the problem still exists, please help share with me a video about this error to my email: yujiamin1@ruijie.com.cn and provide the router SN to further confirm whether it is hardware failure. Thank you for your cooperation.


Best regards
Jenny
