When I power on the Eclipse
I can only hear relay click sound
and cannot see any booting screen at all
No keys working so I cannot even try your suggestion at all

Do you think that update or downgrade program can damage bootrom?

or I am in hardware problem by accident while updating

thank for quick reply

Because it’s hard to send eclipse to usa and cost a lot, i want to fix the problem in my country

so I just want to get any clue what is the cause
