SGS2 wont power on? - Galaxy S II Q&A, Help & Troubleshooting

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.

Whats NAND memory btw.. could u please enlighten?
Thanks! :good:

NAND = the internal storage (sdcard).

hard brick advise

hi i have hard bricked my sgs2, it happened while i was restoring a rom from rom manager and my battery died. what i need to know is whether its worth trying a jig because from what i have read ,if the damage is in the emmc chip its un recoverable. and yes i have tried putting recovery mode and download mode but the phone is comlpetely dead , i have two batterys and a desk charger so i know that the battery is ok.. is it worth buying a jig and waiting for it to arrive just to find it wont work or do i put it straight in the shop.. the question is will a flat battery during a restore damage the emmc chip or is it recoverable in anyones opinion. thanks in advance guys............UPDATED ON MY LAST THREAD
Well since there is no such thing as a "soft brick" there is no such thing as a "hard brick". Your device is just "bricked".
Yes its probably worth getting a jig, they cost about £1 of ebay or you could even make your own so why not?
If it is your chip or bootloader then the device is most likely screwed and you will need to send it away for a JTAG or maybe mobo replacement.

Well, if you used triangle away to remove the yellow triangle and reset the flash counter, they wont know whether it was rooted or not. Plus, in a hardbrick, they cant access anything, so you're safe anyways.

It has happened the same to me,from rom manager,worst apk ever.
If your device is under warranty Samsung must fix it for free,they cannot proove that was rooted.
I was afraid for the same reason but in a hour they had fixed it with the last ics update,they dont asked me anything, the evening the device was root again..

when you revive your phone or get another please, run away from ROM MANAGER. that app maybe good for other phones but it's very deadly on our phone.

[Q] Samsung Galaxy s2 SGH-i777 motherboard

Hi guys,
I was installing one of the custom ROMs and i dont know what happened after that... the phone is not booting up... not even in Download / Recovery Mode. i tried
1. Removing battery & putting it back in
2. USB Jig method
3. Riff-box JTag...
Nothing helped. Also, the phone heats up unusually when i insert the battery... Finally after lot of research i found that i777 had eMMC issue & probably it is corrupt, so the only option left for me is to replace the Motherboard. I currently stay in India & there are no shops here which can provide me this phone's motherboard.
Almost, for 2 months i hav been taking this phone to different technicians, but no one could repair it. Now i dont know what to do. Please Advise me.... What can i do to bring this phone to life?
What rom were u trying to install? What rom were u coming from? Please make sure u have an i777 and not an i9100 or i727 by taking out the battery and looking underneath. It will show the model number. The emmc brick bug refers to the ics stock kernel having the "mmc cap erase" turned on or something to that affect. It damages the emmc chip doing a factory reset. So unless u have the stock ics kernel that shouldn't be a problem for u

Same is the case with me. Motherboard is damaged of my sgh i777. I also looked around a lot to get it repaired. The original Motherboard would cost around 10,000 INR. I found a technician who would fix it with a used motherboard @ cost of 4,000 INR

[Q] Hard Bricked S3 i9300

After Flashing Latest CM10.1 to my S3 and using it for a while, I wanted to go back to stock. I flashed stock 4.1.2, rooted it and installed CWM successfully. After a while I noticed that CWM can not mount internal SD card, or recover a nandroid backup from it. I thought it is a partition issue, so i have decided to flash GT-I9300_mx_20120220.pit to my S3 with re-paration checked. ODIN started the process, Pass appeared with green background. Since then, the device wont start in any mode. I tried every key combination with no luck. Tried to connect the device to pc, same result; device is dead. Pulling battery also did not work.Anything I can do to turn on the device in to download mode at least? Please help me. I am from Lebanon; here all the phones are sold with no warranty, so returning it to Samsung wont solve the problem? any solution? Thank you.

However, there may be a person on here that has had the same issue and managed to fix it (but i doubt it) - be a bit more patient and see if anyone else comes into the thread :good:

90% of phones in Lebanon are sold through unauthorized sellers. If you want to buy it from Samsung agent here, you will end up paying $200 more. Bought my phone for $520, while it costs around $700 from authorized seller.
Is either that or a $200 + mobo replacement.

[Q] HELP my Galaxy S3 is dead!

I successfully rooted my phone and successfully installed the volume hack package and the battery fox for 4.0.4 (both I found how to do on this website) and for a good few months my phone was working fine on Android 4.0.4
Then one day I was replying to a text message the phone just switched itself off and wouldn't get past the boot screen where it comes up with the Samsung Galaxy S III logo. With no one offering me any help when I've posted about this problem on this site and various others and after searching google for days to find a fix as I am a Mac user (Heimdall) with no access to a PC (Odin) at all, I took it to a local phone shop, explained the problem to see if they'd be able to fix it. They had it for 2 weeks and when I went to collect they told me that the phone ended up having to be sent to Samsung and there was nothing they could do with it. (I figured that anyway as it was rooted). Now I have got the phone back, it's in a worse state than what it was when I took it into the shop. When I try to power on the phone, nothing happens at all, it's just a black screen. I assumed the battery might be flat so when I went to plug in the charger, the battery symbol shows but it's got a circle in the middle of it it as though it's loading but nothing else happens.
Does this mean my phone is completely dead for good with no fix at all?
If it's bin fodder I may as well sell it for parts and try to get a bit of money back out of it as I bought this SIM free and it cost me quite a bit back when it first came out.
I'd appreciate it if I didn't get a load of snotty remarks as though I'm the thickest person on earth! I am fairly new to all this and it's all I ever seem to experience from this website. Please only reply if you have a genuine answer to my problem.
Thank you.

Thank you for that, I'd never heard the term SDS (Sudden Death Syndrome) before. I didn't even know it existed! But anyway since you mentioned that, I did a search, found this link http://www.freesamsungrepairs.com and I called the number, they reckon they can fix it free of charge providing there's no physical or water damage (which there isn't) and all I have to pay is the postage fees! Sounds like there maybe some hope after all!

[Q] about warranty and Samsung official support to SDS

My gt-i9300 is died two weeks ago due to a SDS. It is soft bricked, can be opened only in download mode and product name looks empty. It was rooted but since nobody can reach into the internal SD card, how can they prove that it's rooted? Its warranty is still active. Do you think they replace its eMMC chip or full motherboard for free? Is there a chance to recover the old data? I don't want anybody in Samsung official support desk sees my lost data for privacy issues. What are your experiences with them? Thank you for your answers folks.
If the flash counter is not zero and/or status is modified then they may reject warranty, although it has worked for some people.
If it really is sds then the motherboard will have to be replaced. Your data cannot be viewed or recovered if the emmc chip is broken.

Thank you for your kind reply. Well it had %40 battery when I went to bed. It wasn't plugged in for charging. When I woke up the next morning I found that it was shut down and when I tried to open it I saw the one in the attachements. The other one is what I see in the odin mode. I will try my chance anyways.
Looks like sds to me. If you are in Europe then the custom status shouldn't break the warranty.

Thank you again.
after support center edit: They took the phone without any complain, I took the risk and told them it's unrooted, they didn't ask it though. They replaced the motherboard, flashed the 4.3 stock and gave the device back to me in 4 hours.
Samsung surprised me today.
Thank you all dear xda family.
