Hi.
I have an SGS2 i9100 with RootBox 4.1 Stable. I received a Whatsapp message and when I tried to unlock the screen it kind of delayed a lot and hanged up, so I decided to perform a restart by holding the power button until the SGS2 boot image appeared. The boot sequence began but never finished... it continued to show like if it was starting... so after a while I performed the same action, holding the power on button, but it didn't restart, so I directly pulled off the battery, put it back and tried to power on the phone again... but now it is completely dead. No reaction whatsoever. It doesn't even show the battery charging animation if I plug it to the charger. It also won't react if I try to boot it into Recovery mode. NOTHING.
Can somebody give me a hand with this? Is there some way to diagnose what happened to the device and to recover it from the current state?
Thanks a lot in advance.
Regards,
César.
that happen with me , Sudden Dead
So , might (Jtag/Riff box) Revive your phone ! i've tried it and no avail
No chance to recover it or the data. Service centre = replace motherboard (or replace it yourself with a 2nd hand one).
Thanks for your responses, guys.
Given the price of the equipment for doing the jtag solution, I think I'm going directly for the motherboard replacement.
Do you guys know of some online store that sell them on a fair price and do international shipping? I'm from Argentina...
Thanks!
Regards,
Cesar.

I got the service manual for the device, and found that it could be the IC CPU or the one for the power supervisor (UPC400 and U501 respectively, as the components shown in the schematics). I also found this web where they sell the components separately (even the motherboard, which is more expensive than the ICs):

Do you guys know if it's possible to replace the ICs from the board in an easy way or should I replace the whole thing?
Thanks!
U must send it to Samsung service center

Technically, you'd think it was possible. There are a few problems with that though... Firstly, you don't know exactly what's gone and what is still ok. If you did, then the second problem is soldering microelectronics. If you have the correct tools & experience in that, then it's possible, yes. My personal opinion? Much better off to replace the motherboard.

Think I bricked my phone somehow. To the story, I had phone in download mode to flash the leodroid rom which didn't flash at all, as I waited for 10mins to see if it would flash, but to no avail. Anyway, after that I disconnected the phone from pc, removed the battery, inserted the battery again then BOOM! Nothing, no download mode, no recovery, no boot screen, just a blank screen, a brick.
Dunno, if anyone else has had this problem, but if you managed to somehow get yours working again please tell me! And if you can't, guess I'll have to send it back. Anyone know how to deal with online shops, when returning phones?
Cheers in advance.

I`m assuming you`re unable to use volume down + Home + Power buttons together and keep holding them until a menu appears on the screen?

I'm no expert when it comes to things like this
but if you can't access download mode via the button combos
have you tried using one of these 'usb jigs'?
http://www.youtube.com/watch?v=9YRPWU4waa4
it should force your phone into download mode
i think you can either purchase them from a member of this site, forgotten his name :\, or there are plenty of options on ebay

Leodroid, I am guessing this is not a SGS2 rom ?
Well hopefully a JIG works, I have ordered one from ebay earlier this week, hope it comes soon. And yeh the 3 button combos doesn't work. Although I thought the jig won't work if you're unable to power on your phone. Guess I'll give it a go regardless. It wouldn't hurt to try.
Cheers the the help guys

it is, although its under investigation right now.
i had this issue but i was able to go back using 3 button procedure.
i would suggest you take battery out and pop it in and immediately hold the 3 buttons and don't let go until you see something on the screen.
Also, i made my usb jig the other day .. it literally took 10 minutes cutting thru the usb. Just go to any electronics shop and get 300K ohms transistor. put the usb you made in your phone and connect the transistor with your hand on the correct pins .. no need to even solder anything .. just make them touch for few seconds.
My brother held the phone and i held the transistor ... poped the battery in and i was at download mode.
best of luck.
Hi,
I have exactly the same problem here with my phone, a brand new Samsung Galaxy S II.
After trying to flash a new firmware I rebooted my phone into "Downloading mode" and starting (i think) a veery earli version of Odin3 software. But when I didnt know what to do I just shut down my phone and closed the applikation.
And then: Totally stone dead, as a brick. I have ordered a USB-thing from ebay, but I'm pretty sure it aint going to work. No response on either powerbuttons, combos or anything else. Just a black screen. Is the only solution to send it in to Samsung service center or is it any else more possibilty? (Excuse me for bad grammar.)

Why would he need to do that? He can't even see the Download mode screen. How is anyone at Samsung Service center going to see a counter that won't even come on.
Samsung Service Center is going to just jtag flash it, then send it back. Which also wipes the counter, and even if there is a hidden counter, it's erases that as well.
Anyways, I don't think the USB Jig would work. USB Jig will only work if the bootloader is still intact. The USB JIG uses a 300k or 301k resistor, not transistor.
The reason the thread is closed is because it was based off someone else's work, and not giving any credit.
I have been running Siyah 1.7rc1 dual booting Omega v30 as primary and AOKP milestone 1 as secondary. I also have the 4.2 camera and keyboard mods installed. The phone has been working fine until last night.
Last night the phone was fully charged. This morning the phone was off and wouldn't turn on when I pressed the power button. Hoping it was just a depleted battery, I put the phone on the charger for a couple of hours. However, it still won't turn on. I can't get to either recovery mode or download mode with the vol_up+home+power or the vol_down+home+power.
There is no reaction from the phone to any combination of buttons. I have removed the battery a few times with the same results.
Does anyone have any ideas? I might try and see if Samsung service can fix this but wanted to know if there was any advise from XDA.
Well if you do want to go to samsung service """ you have a freaking rooted phone bro"""""",,,BTW your phone is dead.
As repair is chargeable i would first try a new battery or borrow one and a USB jig to boot to recovery mode .
jje
*sob*
Mine has gone exactly the same way.
Had it on charge. Took it off charge and checked emails then left it on my desk. Came back 30 minutes later, picked it up and phone was completely dead.
No light when plugged into a charger, phone won't power on.
Plugged it into a computer, no luck.
Different chargers, different cables, no luck.
Tried a USB jig, no luck.
I've NOT tried a new battery yet, that's next on my list. I suspect this won't make any difference either.
I suggest you send it to samsung bro.
happened to my phone too.
They won't find out you rooted/have custom ROM etc, cause this is caused by hardware failure. They'll need to replace it to get it to boot, so they can't tell if you rooted or not.

take it back to the shop first, if you havent had it too long them may just swap it out. If not then they will send it back for you and should lend you candybar phone to use if you leave them a deposit (depends on the shop though).
Sammy wont even both to check if its been rooted, they will just replace it.
Thanks both. I'm going to send it straight to Samsung as soon as I've found proof of warranty. Hopefully it won't take too long to sort out.

I did try using a friend's battery. No go. I saw another thread on XDA where a bunch of people seem to have hit the same problem in the last week. I am wondering if it is some time-triggerred bug?

I've just got round to trying a friends battery too. Likewise, no go.
I think it's probably more likely a design flaw on Samsungs part.
I wonder if they've produced a different revision of the S3 circuit board to fix it? I've heard on other threads that Samsung just replace the system board when it's sent back for warranty repair...
Well there certainly has been quite a lot of them over the last 4 weeks or so. Probably some sub-standard motherboards found their way into the production line every now and then (given the number of units produced), or a design flaw as noted above. It's going to be a reasonably expensive exercise for Samsung if they end up having to replace a lot of them though...
I just hope that the new one they put in my phone isn't going to commit suicide again in 4 months time

I have the exact problem.
But it was my fault in this case. Flashed an "unmatched" md5 file of WanamLite.
It booted up normally. Then i proceeded installing TiBu & restore apps. After 10mins, i came back with a dead phone.
After some googling & advice from phone shops, there's a possibility that the motherboard may be fried.
I sent to Samsung Service Centre, and within 2 working days, my S3 is alive.

Hi everyone,
I'm writing here cause I've got a really big problem with my lovely Samsung Galaxy S II: the mainboard stopped working.
The really big problem is that I don't know the real problem.
I have two SGS2, one black and one white. The one with motherboard issues is the black one.
I've tried to put the black's motherboard in the white phone but the phone doesn't turn on, neither with a full charged battery (I have something like 4 or 5 batteries for my Galaxys, so i'm really sure that isn't a battery problem) and neither with the usb jig (again, I'm sure that the jig works cause I've tried it on the white one and it works).
I've also tried to put the white's motherboard into the black phone and everything works well, so the black phone's mainboard is broken.
Here comes the problem: I don't know what it happened to the mainboard to break, the last time I saw my phone alive was when I looked at the time on the phone (I mean lockscreen, you know) and after I looked at it it turned off and never woke up (turn on).
Since my hardware skills are quitly good I tried to have a look at the mainboard itself, but it doesn't look damaged in any way, neither fired.
My first worry is about data, I've did a full backup of my phone 2 or 3 days past the damage but I wanna try to recover the latest data that are still stored on my phone.
I've also thought about order a new motherboard from ebay, but the data is still on the broken one, so it will be unuseful.
I attached to this post also 2 photos of the "broken" mainboard (front and rear, taken with my other Galaxy S2)
Any help will be appriced
Thank you in advance guys, I hope to recover data / fix my phone!
Couple of things:
1) This belongs in Q&A
2) What ROM where you on at the time it went off? What kernel?
3) You could try jTAG, 25-50 bucks.
4) The reason why it would be a guessing game, maybe some nasty Sleep Of Death, like those happening with the SIII.
5) Ask the mods to move this thread.

Thank you gastonw!
I read about the JTAG but didn't understood if I only need the JTAG itself (I mean, this => h t t p : / / w w w . gsm-technology .com/multicom/pimg/sam_i9100_400B.jpg ), or if I also need the RiffBox (what's the difference?)
Anyway, when it turned off the ROM on the phone was CyanogenMod 10.1 - 20130703 - NIGHTLY (obviously i9100)
Sleep of Death? I read about this, and the problem is: how can I determinate if the phone wakes up when I insert battery and Jig? I tought to use a voltmeter, but I really don't know where to place to avoid also short circuits.
About the thing to move the thread, yeah, sorry, I noticed just after I created the post. So, If any mod would read this, please move to Q&A
You can do both as you know your hardware.
Of course the smart choice here is to pay for the service instead of becoming the service by purxhacing the riffbox.
Before you do that hit the download combo without the battery (ask for an extra hand) and re insert it while your still hitting it.
When you plug it, does it get hot near the camera?

Again, thank you gastonw! I tried todo the download combo (VOL DOWN + POWER + HOME) while inserting the battery and nothing happened, near the camera the temperature is the same as before.
Anyway I still didn't understood a thing: could the JTAG operate itself or I need also to buy the Riffbox?
jtag is the service the riffbox (and such) provides.

I ordered a Riffbox from Ebay (fonefunshop, an official reseller).
I didn't wanted to pay for a service like "send your phone and we'll revive it" because I don't trust them and I don't want my data to be see from others.
Thank you for your support gastonw, I'll let you know when the RiffBox arrives if it works
Please do, if you can get the hang of it you will be able to help other people plus -maybe- get a buck or two

Hi,
I wasn't doing anything special with the phone, but it was acting weird - didn't allow me to make calls, hang them up in the middle, and restarted the phone, until it didn't turn on again.
It's now completely black, connecting to charger doesn't do anything either.
I tried different batteries, didn't help.
update:
After putting the battery in and trying to turn it on, even though nothing is visible - the phone gets warmer after few minutes.
I'm pretty sure it's not the screen because I would've hear the opening sound and feel the vibration..
Please help!
Thank you
Nobody here can help you with a hardware issue, you should know that having been here for as long as you have. Service centre or local mobile repair shop for diagnosis.
I already saw posts here with the same problem and some suggestions to solutions from other users.
Thought somebody here might try to give an idea so I'll know better when I go to the repair center.
Does it boot in recovery (home+ volume up+power) then wipe data factory reset if it boots in download mode(home+vol down+power) the download stock tar and flash it via odin otherwise hardware issue

'until it didn't turn on again. It's now completely black, connecting to charger doesn't do anything either'
Why won't people read OP/threads before sprouting nonsense on here.
OP - There's been one poster on here who seems to think this issue might be solvable by replacing the 'power IC' (whatever that is) on the motherboard, but the normal fix (if you want it fixed guaranteed) is to replace the motherboard. Reason being, if there's more than one component dead on the motherboard, you're going to pay twice - once for the individual component replacement which doesn't fix the problem, and again to replace the motherboard which will fix the problem.
Better to do it right first time.
Went to the service center
I gave it to the service center, they said it's a serious short circuit and they're probably going to have to "JTAG it".
I asked them if there is any way to save my information before they do that, they said no.
My question is to you - do you agree? Or can you think of a way to backup the phone before that?
Isn't there a way to read the memory using an external device and back it up?
I need a quick reply.
Thank you
Nope, if you don't have it backed up, no chance. Although, there's a very slim chance a company that specialises in recovery of data from dead hard drives might be able to. Expect this to be very expensive if it is at all possible.
Also, there's a fair chance a JTAG won't work as well, it's quite possible only a motherboard replacement will fix it. But you might be lucky.
Thank you for your quick reply
Another update
Hi,
There's another update - they now say they need to replace "power component".
Google search didn't find anything called "power component".
They also said that replacing that component will cause the data to be lose.
What do you think?
Thanks
Hello, yesterday my phone freezes and I couldn`t make a restart, I removed the battery but the screen still worked 30sec, now the phone does not want to start, I tried to make reset but nothing. Any suggest what happened or what can I do? Thank you.
If the phone won't boot at all, you don't really have many options. Try a jig & see if you can get into download mode. Also search for KingRat's 'jumpstart' method where you try and boot the phone with just the charger/without the battery.
Failing that, you could try another battery, but be aware that is unlikely to be the problem, and you'll end up with a new battery you can't use if you decide to get a new phone rather than have this one repaired.
Service centre or local mobile repair shop, most likely fix = motherboard replacement.
As to why/how it happened; who knows ? We don't have the phone in front of us & opened up in order to diagnose it. Nobody here can tell you that.

what do you think, the problem is with a hardware (i need to replace something on the MO) or with the phone`s OS, can a JTAG help me?
@MistahBungle has spelt it out pretty clear......you CAN'T replace individual components on the motherboard..... attempting to do so is just asking for trouble......
If your phone still has warranty, DON'T try JTAGging, Samsung WILL see that this has been attempted (due to the fact that wires have to be soldered to the motherboard to connect the JTAG) and they WILL shout "unauthorized rework" and "warranty void".......
