Same advice as this thread (I.E try the things I suggested to that person); though in your case it's 99.999999% likely you're going to need a motherboard replacement if you intend to keep the phone.
If it's important enough to cause you grief if it's lost, back it up. No excuses
Trolling for thanks is lame
Does Samsung's auto-brightness implementation crap drive you to self-harm ? A solution !
Failure to search is the leading cause of male impotence on XDA
If you don't know how to recover if things go wrong, what are you doing flashing custom roms ?

i cant find usb jig over here...
the person sttill able to go downlad or cwm.. this phone unable to turn on.. tried jump start by holding 3 button and insert battery do not work..

can i know how long should i hold the 3 button? as the post say too many people release early..

if the mobo really spoilt, will it affect the internal memory? for example i sell it to faulty phone shop, do they able to recover? if not maybe sell it and get a new phone

1) You hold the buttons as long as you have to - if it hasn't booted into download mode having held the buttons for twenty seconds, it won't be ever.

2) You can order a jig on eBay; you don't have to find one 'over here'.

3) Nobody can access your internal memory (including you). It's probably dead anyway.

If you decide to keep the phone, you get a motherboard replacement. If you sell it as is, expect to get very little money for it (the only part useful to someone else will probably be the screen).
If it's important enough to cause you grief if it's lost, back it up. No excuses

Correct. Heat at the back + no boot = one or more components on the motherboard have died. It is impossible to read the data off an EMMC in these situations

As I said in my PP, if you sell it, the only thing which be useful for whomever buys it is the screen, assuming they don't replace the motherboard & get the phone working again, and as the EMMC is on the motherboard, new board = new EMMC.

Nobody is going to access your data if you sell it (and even if they could, why would they ? You're paranoid/read too much of the hysteria the tech media push as 'journalism'); it's gone (and I'm not saying this again, twice is my limit).

You can replace the entire motherboard for around the same price. We've seen a number of posts over the past 12 mths or so with this 'replace power IC' fix suggested, but nobody has posted after saying the repair was carried out successfully.

It involves replacing an individual component on the motherboard, these components are tiny, and Samsung service centres/almost all other repairers won't even attempt such a repair. If this repair is unsuccessful, you will end up having to pay for a motherboard replacement + the cost of the failed repair.

So if the plan is to keep the phone, insist on motherboard replacement. You can source a 2nd hand one online yourself & pay a mobile repair shop to do the replacement (and many mobile repair shops may even be able to source one for you), and as I said in my first para, this will cost you not a lot more than what you've been quoted for this dubious repair, but you will pretty much guarantee to fix the phone first time unless there's other components not working.

By all means choose the option you've been given (replacing the individual component), but be aware there's a fair chance it may not work, and if this is the case you'll end up with extra expense if you end up needing the motherboard replaced.

If it was me, I'd want it fixed right the first time.

Anyways, this is my last post to this thread. Nothing personal, but I've given you the options, up to you/your brother to decide what you want to do, no amount of further to-ing/fro-ing in this thread is going to change that.
