Help S3 problem need help!!

Lurker
Yea so about three monts ago i bought a copy of samsung galaxy s3 GT-i9300, it worked fine untill one day i restarted it and it didnt want to turno on, no problem i jsut entered into boot mode and returned my phone to fatory settings and it worked untill couple of days ago when the same problem happened but this time booting wont start, i start the phone and it just has this lighter black (bluish) colour on it and it wont do anything, i tryed charging the battery and waited for a couple of hours but still no luck.
So i was thinking to buy this device called JIG so if i should do that let me now or if you know what to do, tnq.
 
Hey mate. What do you mean by "copy"?
All a USB Jig does is force the phone into "download mode" so that you can flash firmware onto it.
Will it go into download mode manually? (While its turned off, hold in Power, Home and volume DOWN)

By copy i mean chinese probably made it, i tried to go into boot menu and in to download mode but all it does is show a little lighter black colour and then goes fully black untill you touch any button, i tried chargin it and it shows the battery logo so its not the screen's fault
 
Right. If its a chinese fake then i doubt if getting it into download mode is gona help unless you know where to get the right firmware for it. I doubt if its running samsung firmware :(
