Try go into recovery mode (vol up + home + power)
If can..then wipe cache..and wipe dalvik

Hold the three button lama sikit until it boot up.
If still cannot..then try go into download mode and reflash the phone with stock firmware via Odin

Bro..cool down. No need to charge anymore.
Try go into either recovery or download mode first.
Can or cannot..?
Hold the three buttons lama2 sikit..around 20secs or until something comes booting up.

Yeap..it cannot even go into download mode then mobo fried edi. No worries..go claim warranty at service centre.
Btw..what actually happen..?
Takkan suddenly goes kaput

must have overclock too much and fried it

rumors are that regardless if rooted or not, you are getting a full format and stock rom

think so

you cant enter download mode = gg

No..cannot fix. Have to change for new motherboard.
No worries..FOC. since cannot boot up..they will change it without question.

your phone scenario = my gc scenario, hope asus fast fast return my gc, now using backup 9500gt on pc

Normally take 3 days. Gonna be longer if no spareparts available. Try ask nicely for faster and shorter repair period.

Its already Hard Bricked.. Just go to Samsung Service Centre in PJ besides Highway.. Tell them that you were updating your software via Kies , it suddenly went blank, It cant on or boot up.. They know what to do.. Replace Motherboard FOC since u have warranty with them.. IF all goes well, u should able get back ur set within three days..

Note: I have done that for my SGS s2 Non G model sometime back..

can't find your homescreen from the link you given ?
why you need it ???

what your phone problem now ??

Yup..last chance might be usb jig though i'm not sure whether can be use on S3 or not. S2 and Note i know can.

Try search at garage sales..last time i saw two or three traders are selling it.

Sorry bro..dont know which shop selling one of those

Sorry bro..dont know which shop selling one of those

I have one around my room which i'm not using for quite sometime... I can borrow u if u need it temporarily only.

USB jig may help.

I've similar problem and plug in USB jig and the phone back to again.

Try USB jig first before sending.

You can PM me if you need USB jig.  It's with me and I'm in PJ.

I am using OTA version of jellybean from Samsung ..
