unable to boot up galaxy s2 - Galaxy S II Q&A, Help & Troubleshooting

Hi,
i was taking a photo today and the phone hanged. i tried to reboot it but it got stuck at the bootup screen for eternity. tried to reflash it via cwm but it didn went there was some recovery log failure and i could see that the memory was all wiped out.
i tried to put the phone in download mode and odin-ed it but it got stuck at cache.img and didn proceed so i closed the program and unplugged the phone.
and now the phone doesn even turn on but the processor feels hot when i plug it into the charger.
any help guys?? its quite urgent thanks if anyone had a similar experience.

Dead MB. Service centre (or maybe get one from a donor phone & fix it yourself if you're confident).

dead mb?

would the service centre know that i hacked it, it cant even turn on though

You're only going to find that out when you send it in. If you're lucky, they don't care/don't notice & they fix it under warranty (assuming your warranty is valid). If not, you pay for it.

dead motherboard. Fried phone, bricked.... anything you want. Happened to me a month back, and jst got screwed by $ammy service center for "water damage" because BAT500 had leaked... whereas the leaking BAT500 is a known problem related to the weird way samsung charges its phone (bat500 seems to be actually charging, causing the battery to leak).
I guess you propbably have a similar problem. Would be interested to know how to fix it with a spare MB... would probably require a full dump of the nand??

when i plug it into the charger, the processor gets hotter... is there no other way i can fix it?

Use jig tag to enter downloads mode then flash your phone using odin
Search the web for guide make cheap usb jig tag

I think you're mistaking two things.
USB Jig is plugged in the micro-USB port of the phone, and forces it to enter download mode, however it won't work if the phone doesn't boot at all.
On the other hand, JTAG must be plugged directly on the motherboard, and I'm not sure you can build a jtag cable for cheap (but as I say *not sure*)

the usb jig would work even if the phone doesn boot up?

no it wouldn definitely not. Read what I just posted.
USB jig: phone must boot, so at least you should have an "infinite boot logo".
JTAG: direct chip programming.

watch it again. the phone he uses still displays something on screen even without the jig. Here we're talking 'full-brick': no on-screen display at all, nothing happens, nada.
@previous post: bet 500$ your 300$ jig is a riffbox

Exactly. Somebody is talking out their you know what.

[Q] Removing Yellow Triangle after Rooting

Hi
First time post as have just got a Samsung Galaxy S2.
I did a search on the forum and none of the yellow triangle posts are clear to me.I have rooted the phone and it boots and performs ok. I initially rooted it to Lightening Rom 1.5 and have updated this to version 3. The only issue I have is that the yellow triangle appears. I got a jig from mobiletech video website to remove this. I turn the phone off and put in the Jig and nothing happens? Tried everything and no joy. When I updated to version 3.0 of lightening Rom tried again and the phone still will not turn on. I looked around and the only reason I can see is that the Jig is not working or its a bricked bootloader. If it was a bricked bootloader then the phone would not work so would it be the case the Jig is broken? Is there any other way of removing this triangle that is not rocket science and can be done by a noobie like myself
Thanks
Well, does the phone go into download (and will also show 'erasing download information' mode when using the jig? If not, the jig is broken.
I removed the yellow triangle by flasing the original kernel, and flashing the modifed one back with CWM.
Check your Jig. I never had any problem with mine
Your jig seems to be broken. What happens when you plug it in while the device is on?

He did that. But I read somewhere that you should take out your battery, wait a few secs, put it back in and then plug in your jig and wait for the erase of your counters. Maybe you could try that.

Thanks for the replies
In case there is any misunderstanding. What I do is turn off phone completely. Then I put in the Jig. What is suppose to happen is that it should come on within 3-4 sec with the download screen. What actually happens is nothing not a kick from the phone. I can still turn phone on manually and press the home, on/off button & volume down to get to download mode.Tried it with the phone turned on and nothing. Will try taking the battery out later and then try it. Have sent mobiletechvideo an email to see if they could possible replace it as not sure if jig got damaged in transit. Looking at the jig when its inserted into phone its not flush against the usb port not sure if this is the issue?
If anyone has any other ideas please post
Cheers
Try another jig and not the one your grandfather dances at weddings .

When I insert my Jig while the device is on, it starts to "charge", or at least the device thinks it's connected to a charger. It could also be because my Jig doubles as a MiniUSB>MicroUSB adapter, but if I plug in a normal MiniUSB>MicroUSB adapter, nothing happens. So I still think your Jig is broken. And I doubt it was broken in transit since it should not be that sensitive. So I guess either your phone USB is ****ed up in some way, or the Jig is just broken.
Thanks
The usb works fine as I can connect the usb cable to it and PC picks it up. Not sure how I can check the resistance of the Jig
As for getting another one that is not from my grandparents maybe I will email Michael Flatley and ask him to riverdance on my jig see if that fixes it
Ok going to mail mobiletechvideo to see if they can replace it
Cheers
Ok removed battery and tried it and no joy. Inserted it while phone was on nothing
The below link for the pic shows the jig inserted but its not flush this does not look right. Can we safely say the issue is with the Jig ?

You can say that 100% only after you have tested the Jig on another phone, another jig on your phone, and measured the resistance of the Jig. But at least you are doing everything right and there are no signs of any fault with your device. So I would say even without all those tests the chances are pretty much 99% that the fault lies with the Jig.
Nooooo!
You have a custom rom!
If you just root it, and flash Stock kernel, you wont have the yellow triangle.

Remove the battery for few minutes
I tried that, but it didnt help, I'll do it again now and be more patient...
Nothing, waited 12 min, plugged it to the power, no battery recharging sign. Tried to turn it on, nothing...
EDIT: it's very hot around the camera now... (still completely dead tho)

I think your phone is completely dead now.
Send it to Samsung repairs if your phone is still under warranty. They will probably change the motherboard.

If USB jig fails to work, then there is no way for them to find out anything.
After two weeks they came back to me saying that its the logic controller that is oxidized, which for some reason isnt covered by the warranty, so id have to pay 200 euro for it....:crying:

[Q] S II dead :(

Hi all. I have a big problem. I placed my phone onto my desk before sleeping (my battery was +/-55%). When I woke up my phone did not want to go on. I tried charging it for 3 hours with my 2 pin charger and it still didn't want to come on (the charging battery animation didn't even show). I also tried charging with the USB cable via PC but that didn't help. I used my multi-meter to check if the battery was working and it showed that it contains +/-3.4V (battery is rated 3.5V). I tried to boot up into recovery mode (volume down + home button + power button) but it still didn't come on
I bought my phone at the beginning of the year (brand new) and it has been working with no problems until today. I have essential data on my phone (phone book, messages, apps etc) which are really important and I wouldn't want to lose them. Help would be much appreciated.

But how can it get bricked out of the blue? Was working perfectly night before happened. The only app I installed was Angry Birds: Star Wars (officially from Play Google Market).
Hard to say. Phones (like any other electronics) can die for all kinds of obscure reasons.
Service centre or JTAG repair; if you choose the latter option (assuming it can be JTAG'd & it's not a hardware issue), you could ask the repairer if they can recover your data. Might be possible. Service centre will wipe it if it if it's not a hardware issue, and if it is, they'll replace the MB which means you get new internal storage/you'll lose your stuff.
LOL.
Its happened to me and its just a BUG...
you may have 100% of battery but the phone is showing like 50%(fake)
put the charger into the phone hold the bottom of the usb (the last piece .. of the charger) and move it
(move it when it's plugged into the phone

My phone not showing anything (even fake indicator). I did as you said: held and moved around the bottom of the USB (part plugged into phone), while the phone was charging (using 2-pin charger) but did nothing. I just tested my phone with a friend's S II battery and it didn't help

Same Issue
I have the exact same issue with my i9100. I woke up and it was dead. No recovery mode, no download mode, nada...nothing comes up on screen. It has been a little buggy ever since the ICS update but it has always worked eventually. I put the battery into my friend's phone and his worked fine. I am really hoping somebody has answers and it is just not "dead". I never used a ROM or anything, it's killing me that a $500 can just die overnight like this. Any help would be greatly appreciated!
If your phone is still under warranty, go to Samsung service center.

I can not believe that just happened overnight, the only possibility is that you put some of the room's, if you have a warranty on the device, you can send it to the service and just hope that they will accept it and serviced

[Q] USB connection + stock bootloop

Hi Guys I've looked at loads of other related posts for this but nothing seems to be the same as mine, let me try and give you a bit of background on this it wont be perfect as it is my sisters phone and she doesn't know anything. my sister left her original charger at her boyfriends and therefore had to use a cheaper non-stock one she had. Every-time she used it her phone would play up do things like open the car mode and keep rebooting, she didn't think much of it and used it anyway. Her phone died (ran out of battery) one evening and she used the strange charger to charge her phone overnight this however seems to have caused issues since then it wont boot it goes past the Samsung boot screen then the o2 boot screen then just repeats (sounds like a boot loop) note the phone has never been rooted and is still 100% stock.
So this is the issue I figured using ODIN and flashing the stock firmware would fix the issue but I cannot for the life of me get the phone to pick up on ANY computer at all I've tried different charger cables, different computers, Different OS's, cleaning the port and pretty much everything else the internet has currently had to offer. I really am at a loss here I cant use recovery as its not rooted I cant use something like Kies Air or mobile odin as I cant boot into the room and using ODIN is im unable to connect to any computers.
So I guys I'm reaching out to you here what can I do to fix this I really need some advice :laugh:
Thanks in advance.
Say hi to your sister for me.
Oh and her battery must be dead because of the charger.
Usb port could also be busted.
Get another fully charged battery and check it out.

Phone Died And Won't Charge

Hello,
Well, I was just on facebook messaging my friend. My battery soon reached 30% so my phone entered power saving mode. Suddenly, my phone turned off and now it won't charge. When I plug in the charger, the battery charge sign loads but then goes white and turns off. I tried entering recovery mode (hold power and vol up and vol down), but it didn't work. I tried entering download mode using all methods possible and that didn't work either. I have Serendipity 9.4 installed on my phone and it is rooted. What should I do? Is my phone salvageable or should I just throw it away? I can't go to Samsung and ask them to repair it because I have flashed a custom rom on my phone. I am at a loss...

Look at ur micro usb port of ur phone as well as the micro usb cable that u r using to charge it and see if any of the contacts are messed up in either one and therefore causing it to not make good connection. Or there may be some dirt or something causing the connection between the cord and ur phone to not be good also.
Also u could try a different cord or car charger...

Going by your Name,I guess you belong to some part in Asia( India or Pakistan -Most probably), just like me.
Just go to any Mobile repair shop nearby and give them your battery and ask them to give it a "BOOST" it wont cost u more than few bucks(10-20 INR/PKR) and 10 min's.
Now insert in your phone and that should work.

The fact you were able to customize your phone rules out the fact that you are "JUST BAD WITH PHONES" i have been doing this for months. There come times when I get a phone that just doesn't respond the way it is supposed to. I have two i777 that I am really struggling with right now. One of the previous posters suggested flashing back to stock. I understand you CAN'T get to download mode, that suggests to me that you require "JTAG" repair. I have seen that available for around $35.00. that's not bad. Search EBAY and google and maybe even here.
Goodluck
