Galaxy s2 Stuck at Boot - Android Software/Hacking General [Developers Only]

i had the baseband version XXKPA and i needed to switch to a more stable ICS so i flashed XXLPQ without doing a factory reset, now my phone is stuck at the boot screen. it can enter into download mode, but not recovery mode. I need to fix this asap. Anybody help?

Wrong thread, but that doesnt matter! anyways, pull batery out, press recovery button combination (keep holding) and insert battery. Hope it helps you

Sounds like the same exact problem I had about a month ago after trying to flash a new splash image but messed up some where. I figure that my problem was that I hard bricked my mt4g. I never found a fix. I ended up calling cc and asking for a warranty exchange.
I didn't know at the time but I heard if you have eng hboot you can flash through adb if you get bricked. So if you were on eng hboot you might want to try adb and flash the stock zip file or another rom see if that works.

Could be bricked. Unplug it remove the battery and let it sit for a little bit. when you put the battery back in hold power button down and volume button down. If your lucky you'll get hboot. Then go to recovery and restore.

[Q] Can't make selections in recovery mode?

Hey guys, while trying to flash CM7, I forgot to wipe all data and my phone gets stuck on the booting screen. So when I try to get into recovery mode, it doesn't go to ClockWorkMod's Recovery, but the default one. The problem is that the power button does not work, so I cannot make any selections to wipe data or anything. Only the volume buttons work.
Please help, I'm a total noob and I just got this phone fixed after dropping it not too long ago!
It does work i freaked out on this as well. Go to your selection and hold the power button until it selects your selection
Its takes a few seconds holding the power button to register. Not sure if it's a bug or just the way it was built to prevent mis-selections

Thanks for the reply, but unfortunately holding it down isn't helping so far. I've held it for 60 seconds with no luck.
Then use odin to install a new rom is all i can say.
Sent from my LG-P999 using xda premium
Does it say button disabled?
Try hard reboot volume up and power button. And of that don't work it's probably hardware related. Maybe a bad button

Odin is for samsung phones...... you have to use nvflash
Read this thread http://forum.xda-developers.com/showthread.php?t=1160364 which is five threads behind this one. The answer is in there on the second page.

Does anything happen when you press the power button?
Thanks guys, I was thinking I might have to do the nvflash method. The power button was working fine previously and it turns the phone on. Got to work then drink tonight but I'll let you know how it goes tomorrow. Happy New Year!
Thanks guys! The NVFlash method worked and my phone is back working again!

[Q] help phone wont boot just vibrates

after updating to insertcoin RC5 rom my phone wont start.....it just vibrates then stops the vibrates again......it goes through that cycle but doesn't start up....how can i fix...
Ok first have you tried to get it to boot to the Hboot screen?. Next if you have and it will not then you can try using ADB to manually boot it into recovery.
Pull the battery.
Put it back in.
Hold the power button and down volume until the bootloader screen comes up. Select 'recovery' and hit the power button again.
You should boot into your recovery module. (4EXT or Clockwork, whatever the case may be)
You can restore your saved backup ROM from there.
If you didn't save before flashing the new ROM...you did an oopsie. But all is not lost. You can download another ROM via your computer, transfer it to your SD card (which you can do directly from 4EXT recovery if you are using it) and start over.
You almost certainly did not break your phone beyond repair by just flashing a ROM. So relax. It'll be okay.
phone wont go into recovery mode.........it doesn't turn on all it does it vibrate then stops and vibrate again.
Your ok calm down try my post and see if this helps

Hi,
It may be your battery.
Can you get another one to see if it is that?
Maybe your local phone shop could help you out with that...
You said you get in recovery so hboot is there too if you can't or won't try I am done helping

Worked for me...
I factory reset mine and then installed the stock os md5 to my phone. Works now

How do I get into the stock recovery?

Friend has a HTC Sensation on T-Mobile and is having software problems. I suggested factory wiping and wiping cache in recovery.
Sent from my DROID RAZR using xda app-developers app
go to boot loader ...
(power off phone ,remove battery,re insert it ,then hold volume down + power )
from there browse to recovery using vol up/down buttons and select recovery using power button
once you enter recovery ..you will have a red triangle ..if its stock ...then do a three finger salute (press vol up,down and power at once)..then you will get some options
Thank you sir!!
Also another question, is there a way to reboot (restart) the phone natively on stock? My friend is running the Official ICS OTA if that makes a difference. Or is turning off the phone and back on manually the only way? Lol.

[Q] Can you break download mode? I think my Skyrocket is FUBAR :[

I flashed the stable CM10 and everything was ok.
Then I flashed 4.2 gapps and set some alarms.
Now the phone is in a boot loop so I try to return it to stock with Odin and when I get to download mode I click Vol Up to get in and I see Andy the Android for a split second before I get a sort of Blue Screen.
I'm wondering if I broke download mode somehow. Is there a fix for this?
I'm shoving the battery in, pressing the two volume keys, letting go when I see the download screen, hitting Vol Up to accept, then the phone reboots as Andy pops up.
Note: even when I don't accept download mode the screen will go blue and restart the phone.
Thanks in advance.

I would start with at least trying to get the phone to boot into Rom at minimum start with just pure mohans stock Rom and then work your way back try using the ucle2 leaked after going stock then see what happens what the ish out of that phone and see if that help
that what i would do in your shoes

Are you sure you have the Oden process right, where you don't plug the usb cable in until a certain point in the process. Can't remember... Been a while since I used Oden.

Sounds like that might be the case make sure its not a stuck power button. Try using adb to push a recovery file to phone with cmd if all fails get a replacement

If the power button was stuck I don't think I'd be able to see the download mode prompt.

Make sure you are using the usb cable that came with the phone. I really don't think you have a bricked phone

it could be the sticky power button issue, info on that in the ref sticky, if not the button, then hardware failure, u can try to remove battery for about ten mins then check to see if it is resolved
Umm... I've never had to press volume up to accept download mode... just sayin.

Oh and its not bricked, I'm pretty sure. I got this little dongle thing from Amazon last year for my vibrant, but it works for my skyrocket too, for like 2 dollars. (I guess u can make em also) You just plug it into your phone and it puts it in download mode. Very handy.

Well I don't think it's the power button because I don't think I could get to Download mode with the power button being pressed.
Here's a video of what's happening:
http://youtu.be/SY_dN7qN36w
That's a pretty guick sequence. So are you inserting the battery then hold down the buttons then inserting the cable.?
Maybe give the electrons a chance to flow into the circuits!

Yes. It had to be quick. If I do it slowly it starts the boot loop.
After talking to AT&T I'm getting a new battery. I really hope that's the problem, even though I don't think that's it.

If your phone starts to reboot you're doing something wrong. Download mode should last indefinitely. In fact you have to tell it to proceed to some other step. Re-read Vincom's instructions.
Edit : sounds to me that you are not holding down the volume buttons with the power button.

8. How To Put your device into Download Mode: (download mode is NOT the same as recovery mode)
a. Connect the USB cable to your PC, but NOT your device.
b. Remove the battery.
c. Reinsert the battery.
d. Press and keep down both Volume Up and Volume Down keys then insert the USB cable into your device. (On Rogers phones It's just Vol Down.) DO NOT RELEASE THE VOLUME BUTTONS UNTIL INSTRUCTED
e. When You see the screen warning you about installing a rom w/a yellow triangle RELEASE the volume key(s)
f. Now press and release the volume "up" key, you should now be at the Download Mode screen w/odin recognising your phone. -See Pics Below-.

It says not to touch the power button. Is the power button a part of this? In the video I didn't hold it.
As for the sticky power button, I really don't know. I clobbered it, I listened very carefully to it. The instructions to fix it were like "hit it hard and repeatedly" or something.
When do you think I should be hitting these buttons? before the vibrate, or after? Before the Samsung logo, or after? With power button, without?
Can you hear a"click" when you press the power button?... It's not very loud but definitely a click.

Well here's the thing lobster... On my phone if I replace the battery... Nothing happens... If I now press and hold the volume buttons with out inserting a cable... Nothing happens.
Yours must be stuck in the pressed state although you say it clicks when pushed.??? Don't suppose you have any contact cleaner? Maybe a tiny drop of rubbing alcohol?

So when you take out the battery and put it back in it doesn't try to turn itself on? If you're saying you can put the battery back in it and nothing happens, then I guess the button must be stuck.

Where would I put the rubbing alcohol? Would I need to take apart the chassis/case/housing? I imagine rubbing it on the power button wouldn't do anything.
BTW, sincerely, thanks for the help.
Edit: I bashed the phone, power button first, against the table while it was booting up and I saw my boot animation for a second. I thought it was fixed so I stopped bashing and it just rebooted again.
its 99% the power button, hearing it click is no indication thats its working as its an internal problem, theres 3 links to the problem in the "info" section in the "1 stop" sticky in my sig . taking it apart to get to the internal contact is one way to fix it, maybe the only way to fix it. if phone starts as soon as you put the battery in w/out touching any buttons then its a sticky/failed power button. warranty repair is also another solution
its 1% for a battery and/or battery contact problem
