Yes, that was before he gave me more information. I assumed it was a bootloop, it however seems that his phone is dead.

Try a JIG and see. Also try another battery too.
It indeed seemed weird to me too. I tried my battery in his phone and it also did not power on, and I could not acces recovery nor download mode. I used a JIG and to me surprise that did nothing too. It seems that his phone is dead, in quite an odd way. I never experienced anything like this before, that a phone simply get's hard bricked, just like that. Without doing anything to his phone.
A service center is no option for him, probably the mobo will be replaced but since he has no warranty the expenses would be pretty high.
He's getting a new device, an S3. Only thing that upset him is that he won't be able to recover his pictures of his deceased grandparents.
Anyway, thanks for thinking a long!
