S3 self-bricked lying around on table... Need help on diagnosis - Galaxy S III Q&A, Help & Troubleshooting

Hi XDA Community,
slight problem with my S3:
(16GB EU edition, Android 4.02, rooted, superSU)
Phone was laying on table, half-way charged, when the info LED fired like a new msg arrived, but when I wanted to unlock my device I realized it just bricked completely for no obvious reason.
Screen is black, device seems off. Now there is no reaction to any button presses, USB cable, another battery and longtime charging do not bring any results either.
Now I wonder what type of brick this, if it is know and what a possible workaround / way to diagnose exact error is available?
Can send the phone in for expensive repairs but I could do it myself (no warranty anyways) if I knew what parts to replace
Thanks!

A Jtag cable might unbrick it, or might not. No way to diagnose a dead phone.
If Jtag doesn't work then you have no chance of fixing anything yourself, unless you are confident in replacing the whole motherboard.
If I were going to spend that kind of money I'd pay a few more £ and have an expert do it for me and enjoy the warranty afterward.
edit - just noticed the Android 4.0.2 comment , if you've been running on ICS for a long period then don't bother with a Jtag, the motherboard is certainly toast.

[Q] Samsung S3 won't turn on

I've read a few posts around the internet about peoples galaxy s3s just dying and not turning back on, even after charging. This happened me last week. It wouldn't reboot either. I brought it back to the shop and they were unsuccessful there too. They sent it away to be fixed and are now saying that there is damage to the system connector (they said this is where the charger goes in). They are saying its my fault and I have to pay to have it repaired. I know I haven't done anything that would have damaged this. Anyone any ideas about what I should do? I think someone somewhere is just trying to get a bit of money from me!
If you have sent it to the AUTHORIZED service center than you dont have choice than to pay and get it fixed but if not than get your device back and than send it to the authorized samsung service center, you will have a better recomendation...

Its damaged then you need to go to court to prove your word against them .
If you put in a wrong connecter force a connector or bend a connector you can damage the connection pins .
I would ask for the engineers report as to the problem to decide if you are indeed to blame . Bents pins etc then no argument its damaged by the user .

I need some help diagnosing a dead S2

Hello all.
I'm trying to fix my fathers faulty s2. Here is the story so far;
The device is about 15 months old and started to develop a a fault after 13 months. It would keep going into car mode and it woundnl't except a charge. Cleaning the usb port seemed to only be a short term fix. A few weeks after this the phone died and wouldn't power on.
It was sent back to Vodafone, where they told me it was out of warranty and would cost 120 euro to repair even though it was well within warranty. After this it went back to Samsung where they reported water damage. I decided to have a look at it myself and I replaced the usb port, but it didn't help at all. I've tried a battery from a nexus but there was still nothing.
There is no sound when I plug into my PC or even a power vibration.
It was on stock firmwire so it wasn't a case of bad flash.
I have attached a few pictures. Does it look like water damage to you? If so, what would you suggest replacing?
Thanks,
Niall

Too late, already copied it down :silly: :good:
Whoops.. Edited
Given you've already replaced the USB port (I presume you changed the flex cable ?) in the first instance, it's probably the associated circuitry. I imagine they'd probably replace the MB rather than fiddle around with individual components.
You could do that I guess (get one from a 'donor' phone). I doubt you've got any comeback if they say water damage, you could spend money getting your own reports/opinions saying its not, but that's going to cost you a lot more than $120. It should boil down to what the cheapest option is. At this stage, replacing the board yourself is cheapest, then not arguing/paying them to do it, followed by arguing the point with them & trying to get them to do it for free (which they won't).

Help > I9100G enter bootloop suddenly n dead

the phone on like usual , put aside.. when want to use take it and saw it in boot screen.., wait quite long still stuck there.. take off battery and put back in straight cant turn on.. any idea to revive it?
download/cwm mode both not working... tried press 3 together and insert battery also no respond.. charge no respond too... is it mobo dead symtom?
EDIT: Charge it will hot but no respond
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.

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).

it will turn hot when i plug charger on it.. so it considered death too?
planning to sell it out but only concern people have chance revive it back and get data inside..
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).

credit card data etc.. the phone is my bro 1.. i just asking... yesterday he told be that he bring to phone shop for last time before purchase.. the phone repair people say IC dead,, replace cost less than 100.. but dont know which IC, data depend on which IC...
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.

Hard brick ?

Hi guys,
My phone seems to be hard bricked: black screen, nothing happens when trying to charge it, not possible to put it in DL mode, and even usb jig is not working.
Now I'm fully aware of the risks that go with a bad flash, but what is weird in my case is that it happened out of nowhere: I was on stock rom, phone was suffering from a bad case of slowdowns/random freezes/etc so I decided to put CM 11 on it. Like a phoenix my phone rose from his ashes, battery was holding for a full day instead of the usual 3 hours, no more freezes... but then after 2 days of working like a charm, I just found it plain dead on my desk.
Has it ever happened to anyone, suffering that kind of brick a few days after flashing but not during the actual procedure ? Does anyone has a potential solution other than replacing the MB ? (not really worth it on a 2 years old phone IMO, since there is little chance that I will stumble upon a free MB, and I'm not even sure that it would solve anything anyway)
Thanks for your help !
Nothing to do with the flash. Fact - electronics fails/dies. All the time. All electronics. Often without warning & for no apparent reason other than that's the nature of electronics. I don't know why people are so surprised when this type of thing happens.
Motherboard replacement or new phone - a motherboard replacement will fix the phone; one or more components on the motherboard have obviously died.
http://www.parts4repair.com/categories/Samsung-Repair-Parts/ seems to stock reconditioned motherboards for the S2......double figure prices rather than mid triple figure prices for a new phone.....you do the math.......
My wife says I'm a phone geek....She's probably right

[Q] Sony refusing to repair device

So first I want to acknowledge - I know that when you put a modified ROM on your tablet you apparently void the warranty. So with that knowledge in mind, i'm hoping people might have some thoughts on this.
I had my tablet with the Sony repairer previously because the screen cracked without any apparent cause. Sony fixed it under warranty (after some arguing).
Shortly after I got it back from the repairer, I attempted to install Cyanogenmod on the tablet and something went wrong, couldn't get past fastboot mode, and eventually the battery ran out and wouldn't recharge - even after being plugged in at the wall for 48 hours.
The repairer is now saying that Sony shouldn't pay for the repair because I voided the warranty. They want me to pay $300 to replace the Printed Circuit Board.
I can't imagine how installing different software would damage the circuit board. I think the tablet was damaged by the repairer internally when they fixed the tablet the first time around.
Does anyone have thoughts on this?
I guess not...
Hard to say.
Sucks to have to fight.
Look around for threads about de-bricking. Often bricks are only "soft" and need a trick or 3 to recuperate.
