Very hard bricked HTC One M8(x?)

[extremerogo]

Hello,

My friend gave me HTC One M8(possibly M8x, I'll send picture of model here). He told me that he gave that phone earlier to other friend and what he had to do was reinstall stock, but he f**ked up something there and now the phone gives me this:

I disassembled the phone, and looked on battery voltage and it's fine, when I plug the phone to pc or charger it gives me only screen with charging battery, red led and it's pulsing, and then after maybe 5-10 sec screen is black, and go to the charging screen again. I can't even go to fastboot because it turns off. Do you have any idea for this?
And if it will help you, this is what I see in recovery screen:
*** Software status: Official ***
*** LOCKED ***
