SiPy blinks red

[tanrcans]

Hey,

i am using a SiPy device with fw 3.4.0. Since my device is soldered, i was using ftp to transfer my code. In between i safe booted the device and since then red led blinks, even if i do factory reset it does not go away. Does anybody had the same issue, how can i solve it without connecting usb?

thanks a lot in advance.
