CPE510 V1.1 brick

Hello how are you? A few days ago I installed OpenWRT on my CPE510 v1.1, I found the problem that it worked at only 54mbps, so I wanted to go back to stock firmware. At that time the computer was bricked. Connect the serial cable to the CPE and it tells me the following:

Does anyone know what can I do? Thank you!

Edit: I have another CPE 510 v1.1 with original firmware and working, can I extract any file from it?
