It can boot into a Recovery Mode using adb but not native/factory.
It is a fake but I found that it is observing a packaging only.
It works perfect excluding a Recovery Mode issue.
It’s interesting that it boots into Download Mode no sweat.
And I found a trick to boot into a Recovery Mode - after pressing “Home”+”Volume Up”+”Boot” it shows Samsung logo than “BOOTING RECOVERY…” but very shortly than reboots and runs a regular system boot. If I’ll catch a moment when “BOOTING RECOVERY…” became hidden and press “Home”+”Volume Up”+”Boot” again phone screen becomes black and than regular Recovery Mode boot starts.
P.S. I forgot to suggest maybe it's a hardware problem.
I'm sorry for my bad English.
Any suggestions please?
Thanks in advance.
