Dear all,
Thanks @Leo Laohoo, M02@rt37 and @MHM Cisco World for your advices.
At this point I can affirm the problem is 100% hardware related. We found a way to revive the box: disassemble the router, pull out motherboard, connect power supply, fans and start without enclosure with caution of heatsinks overheating. We booted successfully about 10 times, no CPP errors any more. After that ROMMON and IOS were upgraded to 16.12(2r) and 17.9.5f accordingly.
I guess the root cause is MB is slightly bend, and it is causing bad contact problem somewhere inside MB or chips. For sure, cases like this are RMA only, otherwise you may have a huge PITA when put into production. It may act as a backup/testing hardware, and this is our case.
