phone restarts on power off - Galaxy S II Q&A, Help & Troubleshooting

i installed sensation rom and after tht i lost my phone
first phone says conected to usb eventhough i am not connected. so i changed to cognitions2 it was same for this tooo. but now i am on stock with unrooted now the problem is it gets restarted when i power off my phone doesnt go off..and also after removing the battery and replacing it aotomatically power on my phone. my phone doesnt go off...

Yeah I had this too after flashing around a bit.. You could try flashing again with a full wipe (inc. cache and dalvik)?
Personally I resolved by going back to my CWM backup of original stock firmware before reflashing original stock kernel, but that doesn't help much if you don't have the option..

Take out the battery, so it stays out ^^
A few roms have this "feature" and it's not a bug ;-)

[Q] Problems flashing Wolfs gingabread

So, as title says, I have problems with flashing it. I've tried everything, but I just can't get it working. I saw some answers in his thread, but it's kinda hard to watch for replys there, because it's huge thread.
So, here's what I've done. (this guide http://forum.xda-developers.com/showthread.php?t=1193753 )
Flashed to stock 2.1 rom, rooted it, and installed xrecovery.
That everything went fine.
Now, second part, putting Wolfs gingerbread on SD card, and installing it via xrecovery. That went fine too. When xrecovery says it's done, I just pull battery out, and set up flash tool, for flashing .ftf (karnel&baseband, from WBs thread)
But problem is, when I put battery in, phone starts itself (that boot process or something), and it gets stuck at white "Sony Ericsson" logo. Flash tool isn't responding at all (pressing back button, and then pluging USB in phone isn't working). It just isn't working, I'm out of ideas, and it's making me rage hard q_q
-Any- ideas would be great.
you probably put in the battery too quick after you took it out, I suggest starting over or booting into recovery if possible, reflash wolfs and wait a bit longer after you take out the battery.
edit: if nothing of the above works, try SEUS repair and start over from 2.1
Trick
i had the same problem ,,, i think that you may have rebooted after the flash in recovery,,
To get into flash mode ,, with the battery out put the usb in then hold the back button as you put the battery in..
its tricky but it works !!
Hope that helps

[Q] My phone won't start or boot into Recovery Mode

I was using the Spike Pure ICS rom untill I flashed CM 7.2. Now my phone won't boot into Recovery at all. I tried flashing the ICS version of Lite'ning Rom through Odin, but it gets stuck at "factoryfs.img" and I have no idea as to what to do.
Also, I tried flashing the stock Gingerbread firmware after a couple of hours but it says that the battery is low. Will this method work?
Moreover, will I be able to charge my phone while its in this condition?

Can you get into download mode by holding the power, home and volume down buttons when the phone is off? Also, try taking the battery out of your phone for five minutes and then replacing it. Do you get any splash screen (Galaxy S2 Logo) when the phone is powered on? If you can get into download mode, flash a stock ROM from sammobile.com. As for your battery problem, I can't see why plugging your phone in to the charger wouldn't work. Give the download mode and battery remove and replace a go first.
Chris.
I was able to get the phone into Download mode till yesterday night. Though I left my phone connected to the USB port all night, it now says that the phone has low battery to get into Download mode. That's why I asked whether it would get charged or not!
I've downloaded the XWKL1 firmware and also the kernel and want to flash it as soon as my phone gets charged (if it gets charged!).
Firstly, check the sticker on the chassis of the phone under the battery & check what model you have. Secondly, if the battery won't charge, try another battery. Thirdly, if you still can't get into download mode or any other signs of life from the phone with a new battery, service centre.
Thanks for the help MistahBungle & themadba!!
I flashed the stock GB Rom through Odin. Now I'll root it, flash CWM and start flashing again!!

Bricked?

My phone was running at about 60% battery last night, and working fine. It was in my pocket and it vibrated. I was unable to turn it on or reboot it, even after removing the battery. I tried using the battery from my wife's S2 but still no luck. I tried connecting the power supply but it still wouldn't boot so I left it charging overnight.
This morning it alternately flashed a fully green battery and a fully black battery. If I press and hold the power button it starts the boot process - I get past the Samsung splash screen and see the first "Resurrection Remix" splash screen, but then it reverts to displaying the green battery.
Any ideas for how I can revive the phone??

Ok We cant say its bricked!! Because its booting up but not coming to homescreen rite? Are u able to get into recovery or download mode?? If ur able o then wipe the data cache and dalvik cache, reinstall the ROM again.. If Recovery doesnt shw up.. Then Use ODIN to flash original fw!! Even if u still couldn get it.. Order a USB JIG from Ebay and try getting into DOWNLOAD MODE!! Even after this its still working means ITS BRICKED !!
Start download mode and the flash a new stock firmware . And your phone isnt bricked .!
This is why I always make a backup.
If you can get into download mode you can fix it, if you can't it's a service centre job. Pretty simple really.
Try cleaning charging port..

Uh oh...I managed to get into Recovery mode, did a factory reset and kicked off a re-install of the Resurrection Remix ROM from the external SD and it's hung at 50% (for 10 mins now) - at the "Extracting /system..." stage. I daren't interrupt it.
Any ideas???
Yes stop messing
1: If you dint have to save anything, wipe better to full wipe
Flash a stock Rom using Odin, than start again with custom roms.
OR
2: download your custom Rom again and flash, might be corrupt download.

So it's OK to interrupt this ROM flash, even though it's stuck at 50%? Should I just hold the power button or remove the battery??
pull the battery
But I say flash stock Rom first, lengthy procedure I know, but safer
OK I decided to reflash RR 2.3, which had been running fine for a couple of weeks previously. Immediately after flashing (which worked OK) the boot process wouldn't complete - it got as far as the RR splash screen then died (screen blank, and needed a long press on the power button to restart).
This happened several times. Eventually I removed and replaced the battery and it finally booted.
Does this sound like a hardware problem? I've noticed that the phone often runs quite warm, but I don't know if that's normal.
You have to flash stock rom, only way to know if there is something wrong with your phone, run it for couple days.
Now to the heat issue, it is due to
1: modem
2: kernel
3: both

[Q] plz help, lgog died now wont boot up

I know i read this somewhere in the original sl jb rom but cant find it anymore. i was currently running the new jb rom modeled after the ota update with the lgpnst. I accidenlty ran my phone dead for the first time ever. i now can not get my phone to bootup, it will show my desktop for a brief second than bootoff animation than battery charge screen. i can still access download/recovery/bootloader menu's so i wiped everything, tried reflashing, got the optimizing screen, finished , bootoff animation, than charging screen, so than i flashed the original sl jb rom, same thing, than i flashed the noctorunal 2.0 , same thing, mind you these were all clean wipes in between, they are being flashed because the boot screens change, so i really need my phone, im a locksmith and on call 24/7 i know im dumb for messing with my phone when i need it to work, but i have had no problems till a ran it dead.
Sorry i figured it out, through all my attempts, i figured out what i needed to do, i had to charge my phone in recovery mode to 11% and than i rebooted to system and finally got it to load. It would not charge on the charge screen for some reason it might have though in dl mode or bootloader. I hope this helps someone in the future you probably dont need to wipe and reflash everything. but if you kill your phone, plug it in, hold power plus vol + once bootloader comes up hit vol- twice and press power button, this will bring up recovery, watch to make sure its showing + next to the battery percentage. this may not work for all, but it worked for me.
