I thought that I am really smart and can easily repair S2. I ended up with two broken S2s and I thought I can make from them one working unit. One had a fried motherboard and another one had a broken screen. So what I did is flipped the motherboard to the device with intact screen. The device that I obtained works, however it lost IMEA. I tried almost everything like flashing kernels Roms and some methods to restore IMEA. Still it says Baseband unknown and no IMEA. Did I do something wrong? Is there still hope? Or I will have Galaxy player only. Any thoughts are appreciated.

What you thinking? The IMEI is reset every time you remove the battery to buffer and removed the motherboard, for obvious safety reasons.
I do not think there are solutions, but now forgotten official assistance

No, but it's very hard beacuse you've to repair ALL MOTHERBOARD and change the battery-in-motherboard (it's near of camera chip). :good:

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.

thanks for the heads up guys. figured that was what happened and already issues a replacement

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?
Thanks! :good:
NAND = the internal storage (sdcard).

Hi all.
I have a huge problem with my S2. When I type on my keyboard *#06# i get IMEI null/null. Ive tried everything mentioned here and nothing works. I don't know if i made a backup or not. Some app made a backup and i tried to restore and it didnt work. I rooted the phone and tried several custom roms and it doesnt work.
What can I do?

Edit: I've tried to install original stock rom without success
Any good local mobile repair shop should be able to fix this (re-write the IMEI to the device) for you fairly cheaply (for example, I can get it done for around AUD$30). A Samsung service centre can also do it, but will charge you a lot more.
If you've tried to restore a backup & failed for whatever reason, and flashing stock roms didn't work (it can if it was a temporary thing, which it is sometimes), you really don't have any other option apart from buying the equipment repair shops/Samsung use to do the repair mentioned above. Which is obviously more expensive than paying someone who already has the equipment to do it, you need to learn how to use the equipment without turning your phone into a paperweight permanently (or at least unfixable without a motherboard change), and you'll probably never use it again.
Best option is the first one (local mobile repair shop/non Samsung service centre) if you want it fixed easily, quickly, and guaranteed (assuming there's nothing hardware-wise wrong with the phone).
Hi Mistah.
Thanks for the advice. I will take my phone to thr repair shop. I think that too that its not SW fixable.
Regards, Brix
I doubt it is fixable by you, I mean, you can try the stuff in some of the threads on here (various 'guides' around the place), but given what you've already tried/said, they're unlikely to work. And you could spend days trying stuff for no result, be without a working phone for that time, and still end up having to get it repaired. And given how cheap (relatively speaking) it is normally, my choice every time is to get it done sooner rather than later, for those reasons.
Hi
This morning I took my phone off charge and for some reason it wouldn't switch on and the blue LED was flashing, thinking it'd just crashed I removed and re-inserted the battery but this had no effect. I have since tried the phone with two other batteries, tried to boot it into recovery mode and also download mode and also plugged it into a PC but nothing has worked. The phone has showed no signs of life (no blue LED flashing since I removed the battery this morning) through all of these processes but I have noticed the battery has been warming up.
I tried calling Samsung to get the phone repaired but alas it's now out of its 2 year warranty so I will have to pay to get it repaired. As I've been due an upgrade for a while I will get this rather than paying for it to be repaired.
But just in case has anyone any ideas of any thing else I could try to revive the phone? I heard about the USB jig method but wasn't sure if it'd be any use in my situation?
The phone is isn't rooted and running 4.3 Jelly Bean.
Any advise appreciated.

If you cannot get into recovery or download mode there is not alot of hope im sorry.
Sounds like sds and the emmc chip has died.
You could try a jig as they are only a few dollars but personally I would take the upgrade.
I thought as much. I've ordered a USB jig anyhow, its only £2 so im not to bothered if it doesnt work.
The annoying thing is that when I bought the phone and there was the scare surrounding sudden death syndrome I got an app that checked my emmc chip and it said it was susceptible. However I thought the issue was fixed with a firemware update, so I never tried to get it exchanged (not that I think my carrier or Samsung would have allowed me to do this).

The fix stopped the rom etc from corrupting it all at once and give the device longer life but as its a hardware issue its still able to die.

Ah right, out of curiosity were Samsung allowing people with the susceptible emmc chips to exchange the phone?

Im not fully sure, atleast in my country no, only if it failed within the warranty period.
Ok thanks. Im thinking of buying a smashed s3 off of ebay and switching its main board with my phones one. Providing its emmc's chip is ok would this fix my phone?
Provided the smashed phone works fine otherwise then of course.
As an update on this.
I decided to try my luck and wrote a letter to Samsung complaining that despite taking really good care of my phone and through no fault of my own it stopped working, just 2 months out of warranty. I told them that I suspected it to be the emmc chip as this had been identified as a problem with S3's manafactured at the time I bought mine but my carrier (EE) had refused to replace it even though I had ran an app that said my phone had the susceptible chip.
Samsung amazingly agreed to repair my phone free of charge and yesterday I got it back, fully working!
The fault that was listed on the paper work was:
Replacement faulty Ic/ Pa/ Filter
I'm not really sure if that another name for the emmc chip? But regardless I'm very greateful for Sasmung excellent customer service.
Glad it worked out for you, have you run the insane chip test on your new motherboard?
Hello,
A couple of years ago, I dropped my samsung i9100 and instantly its imei disappeared. Since this was caused by a physical damage, none of the software based imei recovery tactics worked. I did not get it repaired because by the time this happened, a refurbished phone was already getting cheaper than a repair. Now, there is this useless piece of electronics that is only good for taking occasional pics at home and listening to music.
I know my way around with replacing components on several phones (iphones, especially i9100 after countless trials and such) and I can replace the logic board. There seems to be legitimate, cheap i9100 logic boards with components on aliexpress.com. But the thing is, once I replace the board, for all intents and purposes it'll be another device, using the old working components and the shell of my actual phone. with a different IMEI.
So, hypothetically speaking, if I buy a board, replace the broken one with it and somehow flash my old IMEI to it, would it be usable once again? I mean from the side of the carrier network. In addition to the technical feasibility, is this a legitimate solution?
I know phone repair by experience only, so I might be way off. Correct me if i'm wrong please.
Thanks in advance.
Recovering a lost IMEI isn't easy. There are guides to recover it but they may not necessarily work as expected or at all.
As about the hardware replacement - carriers can't know your hardware, they do know the model but there is no real way for them to get data about the hardware. I am not sure about the the recovered IMEI (if you manage to recover it), but I don't think so.
Hope that helped and I hope my information is correct, as that's what I know.

thanks for the reply, you are right, recovery methods did not work at all. that's why i'm considering a logic board replacement.
the pieces of information I have are:
- phones are registered as their imei and the carrier knows the phone as their imei. so imei = phone (for the carrier)
- imei change (not recovery) is possible, if not easy
- i know my imei (it's written under the battery housing anyway)
so from what you say, i understand that if i can manage to get my old imei on the new logic board successfully, all it's fine and the phone will resurrect; assuming the new logic board is working well.

Just searched about an imei change and found a guide, seems actually easy, not sure if it works. (http://www.technostall.com/how-to-change-imei-number-android/)
I guess it might work.

I'll go ahead and order a mainboard then and we'll see what happens.
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.

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.
