S2 will not power on - Galaxy S II Q&A, Help & Troubleshooting

A couple of weeks ago my S2 keep restarting itself and then getting stuck while booting. After doing that a few times, it went totally dead and will no longer power on. I have tried a different battery but it didn't work either.
Any advice on how I could go about fixing this. The device was rooted and was running a custom rom for over a year without any problems.

Give us more info!!"
What rom?
What kernel?

Replace motherboard - service centre = new board (expensive option), or source 2nd hand board yourself online & pay local mobile repair shop to swap (not service centre; cheaper option), or new phone.

the only way is go to your nearest service center and get the phone repaired.

[Q] Sgs2 Board Replacement and IMEI Issue

Hey folks,
Iam from India and i own Sgs2 I9100. Last day it suddenly turned off and when i tried to turn it on it was stuck in booting and i pulled out the battery. But now it doesnt even turn on ,it doesnt even show charging battery indication.Just gets heated near camera.So its Hard bricked. I negotiated with samsung service centre about the price of new motherboard. They are ready to give it for 6k. But problem is that my phone is not indian version. I bought it from australia. So the service centre guys are saying they can get the board replaced but wont Give me IMEI. That is they will just give me Motherboard replaced. I have got my previous EFS FOLDER saved in my pc.So if i get just the board replaced from them can i just copy my efs folder and get my phone back to life. My basic question is that what will come with new board ? which rom ?. Or is it just motherboard without any rom and i have to use odin ?.
Expecting an earliest reply. Iam tensed.

Samsung Galaxy S2 smartphone - Motherboard replacement

Hi All, I have been using S2 since 1 n half year. I have rooted my cell many times , recently I rooted my cell with Jelly Bean unofficial , it was working fine for 1 month , yesterday suddenly cell phone was switched off and it did not restart. When I took it to Samsung service center , the person says , there is problem with Motherboard whcih need to be replaced for 10000 rs. Can any one suggest for alternative / lesser price motherboard / any suggestion. Thanks in advance.
Check eBay/Google search to try & buy a 2nd hand broken phone/with a broken screen (someone on here also managed to find a 2nd hand board on its own about a week or so ago, I don't recall where from) you can pull the motherboard out of & swap into yours. If you're not confident doing it yourself, a local mobile shop may do it for your more cheaply than what you've been quoted for what I assume (??) is a new motherboard as opposed to a 2nd hand one.

[Q] Samsung S2 GTi9100 Dead- Soultion Need.

Hi Friends,
I am new to this website and I am here to get a possible DIY solution to restart my Galaxy S2.
Its been a week now and its not working at all . I have checked almost all videos and thread however unable to find a steamline solution.
My phone was showing Samsung logo in case of power Up however after that there was no responce. Tried several times but no luck.
Later I gave my phone to Samsung sevice station , guy gave the assurance to get it done in 3 hrs as its a normal thing. Today, I got my phone back in a dead state and he says (Sir, we are unable to reboot as it has some harware issue and will cost over 8k INR to change the mother board).
Guys, I dont find it worth investing on a 2 Yr old phone. Hence I want to take a chance to get it started myself.
Please Guide.
You can't. Do you think they make this stuff up at service centres or something ? Not everything is a Samsung conspiracy against users.
If your phone won't boot at all & shows no signs of life, what do you expect anyone here to say ? One way or another, if you want your phone to work again, you're replacing the motherboard. Whether you pay a service centre to put a new one in, or whether you source a 2nd hand one from a 'donor' phone (one with a broken screen which is otherwise OK, for example) & either replace it yourself or pay a local mobile repair shop (who isn't a Samsung service centre) to do it, is up to you.
As you've already mentioned you have a 2 yr old phone that doesn't work, and it won't be working again without you spending a not insignificant amount money. If it were me, I'd be getting a new phone.

IMEI Fix due to new motherboard?

Hi guys !
A few weeks ago, I accidentally deadbricked my Galaxy Note I717 (known in Singapore as the Note 1 LTE/N7005) , so I sent it to a repair shop to get the whole motherboard replaced. I just got it back yesterday, and I could not get a stable signal at all , only LTE and GSM on rare occasions for a few minutes. I checked the IMEI and found out that the software's IMEI did not match the one printed on the back of the phone.
Any ideas how can I get this issue fixed WITHOUT buying a 3rd party SDT Box or such items?
Thanks !
From what I know, replacing the motherboard is like getting a different phone. So, you may need to contact your service provider and tell them that you repaired your phone. See if they can update your account to make your service work on the phone.

[Q] Galaxy S2 D710 by Virgin - Motherboard question

I had a power button/sleep button problem and brought it to a professional chain cell phone repair shop. They tried to repair it by soldering on a new button but it got too close to the power supply and in other words they messed it up. They took responsibility and ordered a new motherboard. Since I have Virgin Mobile do they have to order a virgin mobile motherboard or does it matter?
In other words is the service incorporated in the motherboard or not? (since its not using a sim chip)
If the service is on the motherboard, what steps should I take to port the same number, phone info, etc. on it?
