[Q] SGS2 doesn't start up - Galaxy S II Q&A, Help & Troubleshooting

Hi All,
My battery went empty yesterday and phone turned off.
After connecting charger, the phone won't turn on.
Seems that it won't turn on with charger plugged in.
When charger is plugged in, I get a battery symbol telling me the battery is 100% charged.
When I disconnect the charger and I try to turn it on, it doesn't do anything.
I can go into download mode with the USB cable plugged in, but Odin doesn't connect.
Any ideas?

Maybe dead battery, try with another one

Try USB Jig, if U got one and do batt wipe in recovery... Jig saved my phones ass many times when acting verry weird.. Trying another batt in ur carrier shop would be good idea as well...
Good luck

i experienced the same issue last week...
now i recovered the phone.
First recharge the battery by wall charger. led will turn green instead of red... beware,,, insert battery after you plug in power cord.
second open the back cover, unscrew the screws, you can find the video from youtube to guide you... in my case, one of the connectors was not sitting well.
try it again... it will flash smoothly normally only takes 4 mins to done the whole processing... make sure you have full charged battery during the update.
i am recharging my battery with battery charger now
and i just finish unscrewing my phone and reconnecting all the connector and cleaning the USB and the battery connector
lets wait and see
fully recharged battery and all well connected connector and nothing
so tomorrow i will go for serves ????
I ended up buying an external Battery charger, works well.
I have the same problem here!

phone broke ? need help

Hi
I think my phone is a little broke,
It ran out battery last night so i put it on charge this morning.
was on charge by wall for 10 min to get some battery then swapped over to car when i was driving it turned off now when i try and charge it at work via a usb wire and cplug converter i just get the battery logo with the spining circle for a few seconds it flashes then goes off does this about 6 times then the screen just goes off and will not do anything
anyone know any fixes or has it gotta go to samsung ?
Thanks
Have you tried taking out the battery?
Please let us know if it starts working again.
tried that, its like its not getting the power it needs for thats first few seconds as the buttons at the bottom flash on then off again
With the phone OFF. Leave it charging for four hours using the supplied mains charger.
With the phone OFF do you see a picture of the battery showing how much charge you have when you plug the phone into the mains charger? How much charge does it show?
it comes up with the b attery with a circle logo init then turns off then comes back to that over and over again,
i dont have the proper charger on me just the usb wire and a plug to usb
Think getting somewhere, tried a mates battery that works fine, mates charger wont charge on my phone but will my battery in his, so i guess my micro usb port is broke :'(

Try a battery pull. Try booting into recovery.

I tried but nothing seems to work
Pull Battery, Press and hold power and vol+ button with battery out. Hold for 30 seconds, install battery and wall plug and try to power up.
:/ still no luck, just has the white led light come on
Check the manual for the force reboot thins. I know the Xoom has one but I don't know about the photon. Worst case you try random button combinations!

Try a different charged battery.

This actually just started happening to me an hour ago. I plug in my phone every morning to charge it like normally...nothing, no charge, just a white led. I battery pull, still nothing. I unplug the charger, switch to a different wall socket, secure all the connections, it started charging. So I'm guessing a white led while the phone is off means bad connection, or bad battery.
Try a different charger or outlet before you go out and buy a new battery.
Same thing happened to me the phone required a battery remove and reinstall to get it to charge..it only worked once then i took it back to bb and they exchanged my phone since it was defective ..

Try powering with the Wall Charger instead of the USB in a computer
This must be contagious plugged wall charger into phone woke up to white led and dead battery. Car charger and computer usb works. Tried car charge with ac to cigarette plug didn't work. Now the same car charger doesn't work in car. Tried a powered usb hub didn't work. Who knows!?!?
Update:
Got a stand alone battery charger never had this kind of battery life. Phone charging circuit must have been half bad from day one.

[Q] CM9 Alpha 2 Won't Charge

Hello all,
I was wondering if someone could help me out with the issue I am having. I have CM9 Alpha 2 on my Touchpad and it was working perfectly fine until recently. I was able to recharge it using my Touchpad charger when it was booted into WebOS, however, I accidentally left it on over night booted into CM9 and the battery died and now it will not charge. I have tried to use the Touchpad charger and the screen turns on and shows a dead battery symbol then shows a picture of a power cord and then the display turns off and doesn't charge. I then try using a BlackBerry charger and I plug it in and try to turn it on and it says to reliably charge this device use the charger that came with it and then turns off and doesn't charge. In both instances I have tried to do a hard reset (power and home button) in hopes that would make it reboot and charge but it does not work.
Any suggestions would be greatly appreciated!
Thanks in advance.

You can follow that discussion above... but basically that happens when the battery drains on CM9 (bug). Even if you are able to boot into CM9, if you have the power cable plugged in when it boots, it will not charge. The battery meter will stay at 0% even after an hour of it being plugged in. If you remove the power cable, it will shut off. Like mentioned above, you have to either boot into webOS (keep trying to reboot till you get moboot to load) or maybe get lucky and unplug/replug the power cable while in CM9.
I bricked my touch pad n I couldn't figure out how. I have 3 touchpads in the family n the one i bricked was the last one. Same issue on charge all night but no charge.
Cause was the original USB cable had failed. Just in case u have the same issue plug a blackberry short USB cable into your original HP charger n see if it works. That how I got round my issue. Samsung PC USB cable also works.
Good luck
I nearly lost mine, thanks to this thread I'm charging in WebOS back at 6% from 2%, whew! Thank you all.

Is my battery fried?

So I've been running CM9 nightlies on my phone for a for a while now and everything has been working great. I believe the last nightly I flashed was 5/12 or around there and I've had no problems with it so far until last night my battery was about to die. So I plugged it in to my computer to charge overnight. This morning when I woke up I noticed the phone was dead and was pretty warm to the touch. Now it won't turn on.
I have tried pulling out the battery and letting them both sit for about 30min but it still won't turn on. When I put the battery in and try turning it on the charging icon pops up for a second or 2 then goes away and sometimes it will flash on and off. I think it could be the battery because if I take the battery out and try going in to download mode it will turn on to the initial warning screen warning about flashing and what not. If i put the battery in at this point it immediately shuts off. I just don't know how it could go from working fine to not working at all overnight.
Anyone have any suggestions? The phone is only about 4 months old.
Use your wall charger to charge it.

Sorry I should have added that to the original post, plugging directly into the wall is what I have been trying today and still no luck.
He means why in the world would u plug your phone into your computer to charge especially if it was almost dead. Next time i would just use the standard wall charger from the get go if you're looking to fully charge it.

Every phone that I have ever owned with a USB port I have charged through the USB port from a computer, and I have never once had an issue. When I plugged it in the battery symbol changed to charging so I didn't think anything of it. When I woke up it was dead.

^ This.. I mean yes you can use USB to charge, but USB isn't as reliable for everyday use...
I pulled the battery and then let it sit for about 30 min and then charged from the wall charger for about 30 minutes and it still will not even turn on.
Order a new battery off Amazon or something.
Will it power on with the battery in and the wall charger connected?

I'm thinking that's what I'm going to do. Might take it to Best Buy and see if they can check it since the phone is only 4 months old. Not holding my breath on that though.
Phone will not turn on with the battery in while plugged in to the wall charger. I can see the battery symbol with the little circle when I first plug it in but it goes away after a second or so. The only way I can get the phone to turn on is if I remove the battery, hold the volume buttons and plug the USB cable in while connected to a PC. This brings up the download mode warning screen asking to continue. If i put the battery in at this screen it shuts off. If I hit continue with the battery out if shuts off. I guess the only thing to do is try another battery.
Does it taste like chicken? If so, then its probably fried.

Replace the battery.
welp apparently it fixed itself. I just left the battery in it and let it sit powered off for the rest of the work day and when I was leaving work ready to head to Best Buy just out of curiousity I plugged it into my car charger and it magically turned on. Now the wall charger and USB charging are working as well. No clue what that was all about but works for me. Thanks for the replies guys.
Bah same thing is happening to me with my sgs2. It just keeps showing the battery charging screen then going off. Any ideas?

Your battery should be dead. My dad had exactly the same experience as you did. Try calling att for a new battery if the phone still in warranty.
USB charging is just unreliable: different motherboards may even supply slightly different voltages. Although it doesn't make a difference in normal use, adding a near empty battery to the equation complicates things.
