Help > I9100G enter bootloop suddenly n dead - Galaxy S II Q&A, Help & Troubleshooting

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.

Super Urgent..

First of all I admit that i have done stupid thing.
Before telling this I did HSPL to flash radio rom.
Yesterday I dropped my phone.
And from that time on vibration hadn't worked and booting phone by its own hardware buttons also,not working.
But I found booting only works by following method:
plug in charger while battery is out and then press as soon as battery is inserted again.
Now, what I committed to fix my vibrator was that i tried to disassemble and I got stuck at separating the housing with the screen one.
But I just adadoned to fix it and assembled it again.
After I booted my phone by that strange method above, the touch screen did not work.
So I pressed reset button at the back.
Now it is stuck at the first HTC logo screen. (think it is bricked?)
However It doens't show any information about R,G,D just the logo.
Many time till now the result is the same.
Now my question is...
My warranty is not over yet so I think I can get the new one.
However what interrupts my mind is that "what if they find out it is HSPL?"
But my opposing the question above is that can they see if I did HSPL or not since bootloader doesn't work, and proper powering on of the device doens't work either.
So what is you guys opinion will I be ok to get new one without being accused..?
My other concerns are that what if the boot loader suddenly works... and they find out!!?
And also what if they find out that i disassembled once.. cause the screws look touched..
lol while editting.. the phone got RGDs back although it seems it is rare,now it means there is chance for them to notice it..
You will find that your warranty does not cover accidental damage, so the shop you purchased it from probably will not replace it.
Unless you took out insurance at time of purchase that covers accidental damage.
Your best option, is to claim under your household contents insurance, but once again, check that mobile phones are covered, some policies do not, as it is an item you take out of house.
Thanks for your reply, I am really blured ,because i'm now on relatives house abroad..
Initially when i get back i will check..
unless you have insurance I cant see you being covered I hope you are though, any form of insurance with the HD2 is a must imo
HSPL + visible damage from the fall + disassembly evidence (there's a sticker on a screw that will be broken if you unscrew it, to show it's been opened) = definitely no warranty.
Even if there was any chance you could claim warranty, HSPL modification alone would void it. And unfortunately there is no way to revert unless you install a stock ROM from SD Card. I know it very well cause I just did it yesterday. Had to send mine to claim warranty as the touch screen failed...

[Q] [Advice] Galaxy SIII completely dead?

Guys I owned a Galaxy SIII white GT-19300... had it for 3-4 months, bought it brand new. used really carefully, only had one or two falls that's it.
Finally it decided to crap all of a sudden like it had a silent heart attack, just a couple of hours ago. It wasn't charging or was in process of updating or anything. Just that I was sitting and having a sms conversation where in the middle it just won't budge at all. It just went completely pulseless.
These are the symptoms:
-No display
-Won't power up by any means
-No charging light
-No sign of booting up
What I tried:
-Hard reset
-Remove SIM and SD card, still no activity
-Swapped battery of working S3
What should be the next step?. Thankfully warranty period hasn't elapsed yet.
How should I approach now?. Will the warranty company replace the set or more likely create some unsolvable obstacles, like them assuming fall or label the phone rooted etc?
Thanks for your time

Warrant may be void if its rooted or custom rom or modified status or rom counter above zero .
No way to reset those on a non booting phone .
Dropped damage incurred again who knows until they take the phone apart .

If the phone's truly hard-bricked, there's no way the service center would be able to discern that. Dead is dead.
Agreed, if the phone is truly dead no one in the sammy repair could able to detect that.
Sent from my GT-I9300
I'm sorry but I have to disagree, just because the power port has died, by no means means the memory/storage, or anything else for that matter really is down.. (not that it'll come up, just making a point)
it sounds like you really did everything right to troubleshoot it huh.. well let me just throw a few things out, you probably didnt, but hopefully did overlook..
the cord you're trying to charge it with, could it be not working/charging it?
have you tried another cord, or maybe even a USB cord? was it plugged in when it died? some low quality/defective cords can have some weird effects on phones, like less responsive digitizers, or even short out a phone
did you have any custom CPU settings? over/under clock/volt? had you played with you min/max CPU settings?
it doesn't turn on, did you determin this by seeing no display? seeing if there's any hapticfeedback, or even calling it from another phone and seeing if it rings on the callers side.
I know it seems silly but I'm just throwing out things from personal expirence ..
so now your phone really is dead, well having it under warrenty is great. having worked at an AT&T corporate retailer, I can tell you what happens on our side when you bring in a damaged phone.. well try it ourselves, well ask what happened, if you don't know well ask things like, 'did you drop it', 'or it was in contact with water'. (were actually required to ask, since these things aren't covered under warranty. which let me say, is so broken that we push the extended warranty on you, because it covers basically nothing.. we have a quota that says we need to sell X amount of a list of product/services each month.. but I digress).. anyway, once you tell us it just died out of nowhere we take your phone, put it in an envelope and ship it back to the manufacturer. in the mean time well offer you a loaner phone if you need one (just whatever we have on hand at the time, usually phones we get from trade-ins) (you keep your battery and sim) , and we put a 50 dollar hold on your card (yes on a creditcard, not your account) until your phone comes back in and we get our loaner phone. they'll send you a phone back to us, not yours, usually a refurbished version, then we call you and let you know your phones ready.
NEVER have I ever seen or heard anything ever of checking for root. most of our reps don't even know what that is.. once we submit a replacement form, the new phone is on transit to our shop usually by the next day (meaning they send out the replacement before they get the one we sent).
my advice is once you're sure the phone is dead, take it in to your retailer, tell them it died out of nowhere while you were texting, and it won't turn back on. you don't need to go into anymore detail than that..
clearly I have a problem with rambling this morning haha so ill stop talking there. if you have anymore questions tho, ill be happy to answer. goodluck!

Didn't mention it. I underwent much thoroughly then what I typed.. Yup tried 3 different cables, couple of chargers, usb cable.
And no it really wasn't plugged in. I really was expecting a sms at that time, when it took too long, I took it out from the pocket and voila DEAD!

Tried everything you mentioned and even more then that!
yup lifeless like a brick.
** By the way an incidental finding found before claiming warranty. While having the battery in the phone. It was still warm. Removed it. Became cooler, upon reinstall, it became warm again. What gives??!
It's more like a phone in coma!

Thanks for the detailed reply man, really appreciated. Especially since I was already trying to read the minds of these warranty dealers!
So just a while ago I gave it in for warranty. I was adamant of it going dead while I was doing an sms (although true!).. just said no to whatever cause they tried to find (wasn't any, honest!). They were pressing me though for the graze it got (a month ago).. I said 90% of the phones are scratched, and how many do die? He went okay we'll see then, 'yeah you are right we buy that, most that gets damaged from a fall is a phone with shattered screen!"'. Next question, the tricky one!. Did you modify/update software?
I was like, I keep my phones as stock and was totally acting alien to terms like 'rooting' 'firmware' 'kernel' etc (not being honest, but i'm sure that's not the cause)
He was like okay hand it over, we'll do the rest!
Hopefully they don't ever get to revive the mobo or i'm screwed for real!
my phone just died after flashing morfic A10 kernel. i am running stock rooted rom and the best part my sgs 3 was bought 11/18/12 from target, cant go to download mode, cant go to recovery i even tried adb recovery and download mode hoping to turn on nada, charge for an hour no led flashing. my sgs3 totally dead. called target and they said just bring it and they will replace it with new one if the phone wont turn on. is that mean i will be okay even my phone is rooted?
UPDATE:
Thank God.. got my SIII fixed in warranty, now it's back to life!
Just had a motherboard replacement, no further details given.
Hence kind of proven!:
if the phone is truly dead no one in the sammy repair could able to detect that.

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).

[Q] Galaxy note screen wont come on

I recently took apart my galaxy note to replace the power jack. After i put it all together, the screen will not come on. The phone is on and will be recognized my a computer. The capacitive touch lights come on and haptic feedback functions when they are used. But the screen wont come on.
Were do i go from here.
You will likely need to take the device apart again, and re-trace your steps...
Chances are, you have a bad connection to the digitizer screen, and as you know, those connections are "very" small, and are easily damaged or connected improperly.
There really is no other choice, than to inspect the areas you worked on....g

A little more information, I have the device apart right now.
I bought a used Note off of craigslist that had a broken screen and a bad SIM card slot. I transplanted that motherboard into my phone and the screen powers on. But with my motherboard it does not.
What should I look for specifically when inspecting the ribbon connections
That they are connected completely.

Checked,
Phone reassembled completely, still nothing on screen.
Now what.
UPDATE: Motherboard wont power either screen. The bad motherboard will power both.
What is the defect, on the board that powers both screens ?
It's beginning to sound as if you now have two bad mother boards ?
Or at least, a partially working board.
Either way, the device is still broken....ouch
It may come down to taking the device for repair, or trying to find yet another board.
At this point, getting a complete and working device may be in order, as risking more time and money on devices for parts, isn't working out ..
I'm sorry, I don't have any further advice for you at this point ....g
First, you need to differentiate what you mean by "bad" motherboard, cuz it sounds like both motherboards are "bad" in some way.
Your first motherboard is not powering screen, but everything else works. Correct?
Your second motherboard, bought online with bad SIM slot, powers screen, but cannot be used with the bad SIM slot. Correct?
It sounds like your first MB has issues for screen, which is obvious, because the screen works with the second MB.
Then, you may try to replace the SIM slot on the second MB. I think figuring out the problem with the first MB will be exponentially harder, let alone fixing it.
Or, just sell EVERYTHING you have and pony up some cash and buy a working phone, instead of trying to fix this thing. Since your MB is recognized by PC, you can still save all your data.
Agreed ..g

Yes, I apologize. Let me clarify.
Motherboard #1: Does not power screen, but works fine otherwise.
Motherboard #2: Will not read SIM or microSD cards, but powers screens just fine.
I looked into what replacing the SIM and microSD system on the motherboard. Its very difficult.
On the sell EVERYTHING front. I recently sold a set of Rims I had for my car. By some miracle, I was eligible for an upgrade with AT&T. Galaxy Note II ordered.
But, if I can get a spare phone working. Id still like to fix this one.
In my opinion ....
Dump them as parts devices ....
In another few months, these devices will be selling cheap ....imho
Note 3 is already being developed, and the 1 will be rolling off the back end by August/September 2013.
I saw one for sale in Utah today for $125.00
So it's already begun ....IMHO ....g

S3 self-bricked lying around on table... Need help on diagnosis

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!
mx2k
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.
