Hard Bricked International Galaxy S3

[Tarek Salama]

My S3 is totally dead. I took it to several repair shops and they claimed that the whole board needs to be replaced and one guy said the power circuit needs to be replaced although I'm sure it's fine (a friend tested my phone with an external power supply). I asked another shop if they had the Jig, he said that my phone needs the JTAG device thing instead. So yea, how can I tell which one of those wasn't trying to scam me? My phone is basically dead, totally dead even when I plug the charger, the LED doesn't turn red. I can't access the download mode either. So yea, any idea?

PS: I was trying several ROMs before it died. The last ROM I had was the CM 10.1 Nightly build, Android 4.3 and CW Recovery.

PS2: The phone kept working for about 9 hours before it died.. It didn't die immediately. Can a ROM kill the phone after some time or does it always happen immediately?

Welcome to the forums!
I haven't heard of that exact situation before, but it may be possible. Could you link to all the ROMs you flashed?

I tried the stable, RC and ended up with the Nightly. I also tried this AOKP.co: i9300, the Milestone (3rd link from above).

Not sure. Every file is correct and for your device. Have you tried a different battery to power on?

Nope.. But a friend tried putting it on an external power supply to check the power circuit, he said it drew some current when he tried to turn it on.

I am honestly at a loss then. Sorry.
