Dear, my galaxy s2 is dead, please, help me, I need recover it, mainly because my unsaved data. It began discharging even connected to the charger, some days after it reboot while charging and has blocked in the samsung logo. I have removed the battery and put it again, it blocked in the samsung logo (I not pushed the power button)... I have removed the battery again and DEAD, no more, nothing...
There is any way of I get my data (pictures, phone contacts, phone calendar, etc.) from motherboard?
Details about the short circuit, with pictures, can be seen in the topic "Insoluble short circuit samsung galaxy s2" at GSM-Forum..
I don't know what I can do. :crying:
Please, help me!
If your device is totally dead (no download mode/recovery), I think the easiest (but not cheapest) way is to buy another S2 (of the same variant), replace its mainboard with yours and pray that the mainboard isn't the broken part itself (but I think it is). I often changed parts of my S2 and I can say it is very easy to open and change mainboard.
But i hope that there will be some other suggestions from more experienced users...

The motherboard is short circuited, unfortunately I can't post pictures (pictures can be seen in the topic "Insoluble short circuit samsung galaxy s2" at GSM-Forum). I would be happy if buy another motherboard solve my main goal that is recovery my data, but I think that not would solve, I think that the data is on the motherboard, thus just change the motherboard not help me to recovery my data. :crying::crying::crying:

For your situation, you can only send your device to lab and ask professionals to do the work.

Are you sure? :crying:
But, is it possible recovery the data? How? Maybe jtag?
Blair Miller said:
Well, maybe you can try some recovery app first. I know a good one called Jihosoft Android Phone Recovery. But there is no guarantee. when your data is lost, the sector used to save data is marked as available. You can not see the data. But the data is still there until new data overwritten the old one.
If the app doesn't work. I am afraid you have to send it to professional lab. And it will be expensive. Anyway, good luck.

No, no... My phone is dead, it not working, the motherboard is short circuited.

You could find some at the internet, and send your phone to them for evaluation, if it still can be recovered, you are lucky. If not, they will return the device to you and won't charge any fees.

I was in the process of flashing cm9 on my sgs2, i succesfully rooted the phone, booted into cwm recovery. Made a succesful backup. When i was in the process of wiping data on device, it took way too long to complete, so i pulled the battery to reboot into recovery and try again, but now it doesnt power up at all. Not system, recovery, download mode... Nothing.
What happened here? Can anyone please provide some advise to relive my phone of there is a chance?

If you were on Samsung based kernel, the phone is completely dead. Can be fixed only with a motherboard replacement. Sorry about that.

I have the same problem of bricking my S2 because of the emmc brick bug. I would like to check is there are any other way to repair the phone without replacement of the maotherboard?
If I send the phone in to Samsung for replaccement of motherboard, will they be returning the faulty motherboard?
Thanks.

When this particular hardbrick occurs, only a MB replacement helps. Not Jtag. Sorry.
Edit: you can send it to Samsung and play dumb. Like 'put it to chrger in the evening, didnt turn on the next morning'.
Btw if the phone memory is inaccesible, they cant really figure out you've been tempering.

For your second question, they won't return your faulty MB. In their warranty agreement (assuming replacement through warranty. Maybe it doesn't count if the phone is out of warranty), they will keep the part that is being replaced.

I am about to have my o/w s2;s m/b replaced. It was clearly mentioned at the back of the service request document that faulty parts/equipments will be returned only on special written request. When I called the service centre, they said its not applicable to parts like m/b. Am I being fooled? Will they repair and put the m/b on resale? what should I do to get my faulty m/b back? any suggestions?
Thanks!
Why would you want the motherboard back when the most important thing on it (the NAND) is stuffed ? Not like there are any other parts on the board 99% of people would be capable of replacing themselves/canibalising to use on another phone.
And for the same reason, they're not going to put a 2nd hand board 'on resale'. Yes it will probably get recycled (depending on the country) like any other electronics. Which means being 'stripped' of the metals within the board/components & those will end up as scrap.

Oh yes... I was thinking about the same thing.. my data on internal storage. I was gonna try to retrieve it somehow Anyway now when you have mentioned its inaccessible I am relieved Yet I'd have loved to keep the m/b as an antique on my desk
Whats NAND memory btw.. could u please enlighten?

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.
Sent from the little guy
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,
Yesterday, all of a sudden my S2 crashed for no reason and I haven't been able to boot it ever since. First, I put out the battery, put it back in and everything seemed to be ok, but when the screen with the Samsung logo came on nothing happened. I tried this a few times, still the same. So I started to search on the internet for soluitons and found out about the 'recovery mode'. I got it into recovery mode and chose 'reboot', and after that my phone totally stopped working...
Now it won't even turn on or anything, when the phone is on the charger there's no sign that it's charging. I've tried another battery but it stays the same. I've got the phone for 2.5 years and never had any problems with it and never rooted or flashed it.
I've searched this forum a bit and I saw some quite simular problems, but because at first I got into download mode I thouigt my case is a bit different. So, is there anything else I can do to help fix this?

Be aware to do this thing..
Thanks so far, but can someone tell me how it's possible that these devices just stop working? Never had any problems with it at all.
You guys think an USB jig etc. won't work? I've recently saved all photos/videos.. But I didn't save agenda items/contacts and such, because there was no reason to believe that the phone would crash in near future.
Seriously ? Electronics of all kinds (phones, PC's, whatever) die without warning for all kinds of warnings. Not like electronic components can give you some pop up warning saying 'Oh yeah, BTW, I'm about to bite the dust, you better back your **** up'.
A jig is unlikely to work, but eh, maybe you'll be the 1 in 10,000 cases like this where it will work. So you definitely try one if you can get one.
Saying 'But I didn't save agenda items/contacts and such, because there was no reason to believe that the phone would crash in near future' is beyond ridiculous. If you've got stuff that's really important to you & the loss of that stuff is going to cause you angst, you're a fool if you're not backing it up regularly. Even on a completely stock phone this is a cinch to do (Kies).

I mean take a look at that link.. people who have dead s2's without even water damage have able to boot up the phone by removing that capacitor...
what do you think ?
No idea, never tried it (and wouldn't). I'd bite the bullet & pay someone to fix my phone properly or buy another one, and I'd also have all my stuff backed up so I can restore it when I get my phone fixed/to my new phone.
Edit - I'm perfectly calm. I refuse to show any empathy/sympathy to stupid people who don't back important data up & then cry when that data is lost.

I'd rather try everything not to have to replace the motherboard. Cause like I said earlier: If there's any possibility to save the phone like it was when it crashed, so with messages/settings/apps etc. it's better offcourse... Or is it when I remove/replace this capacitor all will be lost also?
I'm going to visit the local store this afternoon to see what they have to say about it... But there's no warranty on this phone anymore so I guess fixing will be (too) expensive.

You can't solve that issue. It's not possible. The only people who might be able to (and this is probably a 1 in 1000 chance) is a company who specialises in data recovery from dead hard drives, and even that is very unlikely.
do others have methods to help me??
No.
i want to know what 's wrong with my phone....:crying:
when i try to turn on, i feel that the phone is still a bit warm... it's working right??
Something on the motherboard has crapped itself. No, the opposite. Having the phone warm up near the camera is symptomatic of every single case like this we see/have seen on here in 2.5 yrs. You're not fixing it yourself unless you replace the motherboard yourself, and you're not recovering your data regardless of what you or anyone else does.
Now, you can sit here for 4 days, a week, two weeks, a month in denial & maybe have people tell you to try things that might build your hopes up but have absolutely no chance of working, or you can bite the bullet & have the phone repaired or buy a new phone.
The choice is yours.

Take your phone to local mobile repair shop ... asks for checking short circuit for battery , and Two power IC's .. one located near camera and other lower Right..
ask him to check if something is wrong on both these..
if it does... asks for POWER IC replacement or Motherboard replacement..
If at last nothing works and you are finally going to replace your motherboard anyway
do this thing or ask a technician to do this.. may be it'll work:

Hello experts,
I have Samsung Galaxy S3, I was using messenger then it hanged up and then I restarted my mobile by pressing and holding the power switch. Then Galaxy S3 logo appeared after restart and again hanged up. Then I again restarted the phone, again at the same point it hanged up i.e. at the logo of Galaxy S3. Then I pulled out battery and reinsert it but after this it never started again not even blinked once. I have also checked on another battery.
I went to the mobile repairing shop then he said CMC chip is dead so its circuit will be replaced. Then I went another shop, he said I will flash the device but I don't guarantee about the data (stored in phone storage). I said him that it is not turning on then how will you flash it. He said I will do it yet.
Now, tell me experts that what should I do to get my phone data back? What should I do that it just turned on for some minutes so that I could take my data to SD card. My data is much important. Also tell me how did the shopkeeper say that he will flash the phone even it is not turning on anyhow.
Thank you.

If it's super important, you would've backed it up, right? Everyone I know backups their important data at least 2 times
The other shopkeeper could use a jtag to force the device into download mode (helped me to unbrick a hard bricked s4).
My 2 seconds of Googling brought me to this link.
That's what I'd assume they'd do (that's what I'd do if I was them).
As for the first one, they might be correct, or not. My strongest recommendation is to try the jtag method and if that doesn't work, I will be really surprised if they actually replace the CMC. Usually what they do is just replace the motherboard which you can do at home (there are plenty of motherboards on ebay) however, it's cheaper but your data chips would need to be transfered over to the new motherboard, which is just better to go with the CMC replacement (if they don't replace your mobo, your data is fine, if they do, it's gone with the mobo).
As for the second option regarding your data, unfortunately it's correct. However, it they get into download mode, they can flash a recovery (different partition, meaning your /data partition is safe) like twrp which they can use to make a nandroid backup and then after extracting the backup, flash new rom. Then you can restore the different apps/settings from the twrp backup file (there are plenty of tutorials on the net).

And if you are asking me to read the issue, obviously you are also a busiest person having life issues and others, you can't also read that thread and want to resolve the issue ASAP. Pardon me if I get wrong as my English is not much good.
Hi, ramiabouzahra
Thanks for your reply. Here is what I understand from your reply, I give answer below step by step.
If it's super important, you would've backed it up, right? Everyone I know backups their important data at least 2 times

Unfortunately, I didn't because I was thinking that mobile is working fine, I will backup after a week or two but before I do this, my mobile gone dead
The other shopkeeper could use a jtag to force the device into download mode (helped me to unbrick a hard bricked s4).

What I understand from this, the shopkeeper who is asking me to bring life to the phone, would use jtag? What is jtag and how can I do it at home and what thing like cables, etc do I need for this. Further what I understand, is that by using jtag, the device is forced to go into download mode. Right?
My 2 seconds of Googling brought me to this link.
That's what I'd assume they'd do (that's what I'd do if I was them).

What I understand from the given link, it is a method of flashing the device. Right? By the way, do you think that the mobile which is not turning on anyhow even by trying all methods, it will turn on by flashing the device? But again, as I read the thread that data can be gone. Again, no safety for data.
As for the first one, they might be correct, or not. My strongest recommendation is to try the jtag method and if that doesn't work, I will be really surprised if they actually replace the CMC.

You recommend me to use jtag method? OK. And what is CMC? What does it stand for? How they replace it? Any tutorial?
Usually what they do is just replace the motherboard which you can do at home (there are plenty of motherboards on ebay) however, it's cheaper but your data chips would need to be transfered over to the new motherboard, which is just better to go with the CMC replacement (if they don't replace your mobo, your data is fine, if they do, it's gone with the mobo).

Yeah, I can do this at home as I am aware of little bit electronics. Can you tell me which is suited for my Galaxy S3 on EBAY? Can you give the link so that I could buy? And I hope, I would able to transfer chips on the new mobo, just locate the chip for me which is to be transferred. And further I don't understand what do you mean by the line "which is just better to go with the CMC replacement (if they don't replace your mobo, your data is fine, if they do, it's gone with the mobo"
As for the second option regarding your data, unfortunately it's correct. However, it they get into download mode, they can flash a recovery (different partition, meaning your /data partition is safe) like twrp which they can use to make a nandroid backup and then after extracting the backup, flash new rom. Then you can restore the different apps/settings from the twrp backup file (there are plenty of tutorials on the net).

Here the second option you mean, flashing the rom? you said in the bracket the "data partition is safe" means in this method, I can safe my data? OK, I read about twrp as per my understanding, it can get my data back? Right?
Thank you for answering me, I am a dumb. Thanks for tolerating me.

What jtag is etc can be checked out in the link below. What cables you need depend on specifically your device (it might be s3, but there are different variants of the s3).
And yes, normally that would mean that it would be forced into download mode

Regarding the jtag, you can check out this great forum question and answer Keep in mind that jtag doesn't always need a controller, in my case (s4 not s3), I had to create a micro usb connector with a resistor on one of the ends and plug it into the device for it to work again

I don't really know what CMC is, maybe the guy meant SMC? SMC is a common abbreviation used in circuit board repair and stands for System Management Controller so in one word or another, a chip (correct me if I am wrong, I am not super educated in the circuit board area).
I do recommend you use the jtag method since if it doesn't work, at least you can rest a sure you've tried multiple ways to revive it and not sit and wonder after the board repair is complete if there was a more efficient way to solve the issue.

Are you sure you can do it at home? It isn't normal solder, it's more of a ballpoint solder requiring to heat up the board to let the solder flow and then extract the nand chips. I cannot give you link since I don't know specifically what phone you have (you stated s3, but there are plenty of s3 variants such as the s3 lte etc all with different internals).
What I meant by that line is that since the data chips are on the motherboard, replacing the motherboard means losing your data. If they don't replace your motherboard (mobo), your data is intact/fine .

Yep, with twrp you can create a backup and extract from that backup apps and whatnot. So technically, your data is safe (you will wipe the phone, but you'll have a backup ). If it's photos that are the issue, you can hope that your sync was on and that you had Google Photos set up (automatically backs up your gallery).
