Motherboard not working in Sony Ericsson Xperia Arc

[ValentineSS]

I have Sony Ericsson Xperia Arc. I don’t have any problem with the working of the device till last week but after that I faced some severe problem. I used the method in se site unlockbootloader. now my phone is bricked. I attempted each system in various site to carry it back but nothing worked. Flash didn’t work. Green light is squinting when connected to, enduring green light when joined to PC. So I chose to send my mobile to service center. One week later they told me that phone is not in warrant in view of unlocks and somehow motherboard harmed. And then they told me that they can’t do anything. What I am inquiring, is that plausible. I mean might motherboard quite harm due to this? Of even harmed cant it moves toward getting fixed? Can anyone give me some suggestion to sole this? Please help me.

I am just able to think your occurrence as a co-incidence as opposed to anything else. I.e. you unlock the bootloader and something that was troubling prior gave course at that purpose of time. I'm not positive on the repair as I'm not that specialized.
