Dear user,

Normally a blinking LEDs is not a good sign and the reason may be from a wrong/faulty accessory to defective CPU.In case of single CPU,there is no way to trace the exact cause from buffer because a overall reset happens after recovery.

Instead, issue a support request and ask support team  for  a way to copy buffer content when it not responding due to blinking LEDs.

I hope it helps,
