Samsung Galaxy SII Not Booting? Here’s the Solution

Samsung Galaxy S2 not booting up

Galaxy S2 not  starting / booting? This happened with me yesterday when I was updating Galaxy SII (official update OTA) and after few updates, when the phone was booting up, It stuck at galaxy logo (Samsung Galaxy S II GT-I9100G) and I had no idea what to do next.

Yes, the mistake was with Samsung‘s update as the ROM is official one not the custom one. And Samsung’s PC suite (Kies) is totally useless. Unlike iTunes, it cannot solve the issues with phone when its turned off or not booting up. I had to find the solution on my own, I kept searching and found the methods to solve the boot error with Galaxy S II.

If you ever stuck up in a situation like this, try these three methods in sequence. First of all, perform a soft reset(read below) which will least probably solve the issue and without deleting your personal data. If the issue wasn’t solved with soft reset then there are chances that Hard reset will do. If the hard reset didn’t even work then you need to re-install the firmware using Odin.

How to Soft Reset Samsung Galaxy Device?

  • Take out the battery.
  • Reinsert the battery.
  • Press and hold the power button for 10 seconds.

That’s soft reset. This doesn’t cause any data wipe but this will delete temporary files which you should not worry about. If your device doesn’t load after this, try hard reset.

How to Hard Reset Samsung Galaxy Device?

  • Switch off the device.
  • Press and hold Volume Up + Home Button + Power Key.
  • After 2-3 seconds, release the Power Key.
  • You will enter boot screen, Select Wipe Data / Factory Reset.
  • Select Yes.

This will delete all the files including apps, personal data stored in phone memory. Don’t worry it doesn’t wipe off the SD Card so you should make a backup of your files stored in phone memory. If the device doesn’t boot even after hard reset then there’s some critical issue with phone’s ROM. You need to re-install the firmware, read below to know how.

How to Re-Install Official Firmware on Samsung Galaxy Device?

You have to perform this task using Odin, not with Samsung Kies even if you didn’t install custom ROM. Samsung Kies won’t allow you to re-install the firmware on the device which is turned off /cannot be turned off. Doing this with Odin is simply very easy as you just have to follow the instructions below (From and thanks to XDA-Devs).

Download these required files first


  1. Pull out the battery and reinsert.
  2. Press and Hold Volume Down + Home + Power Button until you see a warning!!
  3. Press Volume Up button.
  4. Your device will now enter the download mode.
  5. Connect your phone to the PC.
  6. Let it install some drivers.
  7. Open Odin and click on PIT
  8. Select that .PIT file you downloaded.
  9. Check the box – Re-partition and Click Start.
  10. After the successful attempt to re-partition the device, Flash with new firmware (which you downloaded from SamMobile)
  11. Browse the downloaded firmware to the PDA section in Odin.
  12. Don’t check the re-partition box this time.
  13. Click Start and wait patiently.
  14. Done! Now your device should start.

    My phone did not start after Samsung pushed jelly bean update. After step 14 nothing happened for upto one hour. I had to do some tweaks which are below. I used the 4.1.2 update.

    At step 9 ensure that the Auto Reboot and Reset time are also ticked.

    After step 9 the phone will automatically reboot and will again stuck at the flash screen.

    Disconnect the phone from laptop and follow step 1 to 6 again.

    Jump to step 11 and ensure Auto Reboot and Reset time are also ticked.

    This time my phone started after step 14. The asked questions related to first setup but I kept getting error popups like badge provider stopped, android.ancore stopped, google apps stopped, etc. I restarted the phone but the same thing.

    I then followed the “How to Hard Reset Samsung Galaxy Device?”

    Now my phone is fine and that too jelly beans.

    Moreover I did not loose any of my data except SMSes which puzzles me. I got all my apps back automatically as I linked my phone to google account.

    Really awesome.

  • soshi

    Do you have to uncheck Auto Reboot and F. Reset time? I kept those checked and after I installed the ,pit, my phone doesn’t turn or anything, it’s like it doesn’t even know how to turn on. If that’s the problem, you have to make that clear.

  • soshi

    EVERYONE WHO’S READING THIS – do NOT mess with the PIT file because you will more than likely brick your phone and that’s good bye to your phone. I just witnessed this happen right now because this guide was not clear that messing you PIT files can seriously mess your phone up. Thanks for bricking my phone you douchebag.

  • uoossoon

    Waited at step 14 for > 1 hour…. help… tried 2 times.

    Now, my samsung is only showing the screen and nothing else…

  • fans792

    DO NOT TRY THIS IF YOU ARE not ready to send your s2 to permanent trash bin. I tried it and my s2 packed up that the Samsung repair center after two days of trying to fix it advised me to get a new phone that the PBA is damAged and the cost of replacing it is almost three quarter of new s2. BETTER BE WARNED. I finally dumped it in the trash and got a new phone.

  • Alan

    Does the instructions work for Galaxy S2 international version too (i9100 ie.). Do I have to download a different PIT file for that? Thanks in advance!

  • Elie

    After selecting the PIT file i have started .. my GT-9100I has turned off and it doesn’t turn on anymore .. and i can’t enter recovery mode or download mode . PLEASE HELP and Thanks .

  • Toxy

    my galaxy SII doesn’t reboot at all (not even with the hardware button fro a factory reset.) But on the Sammobile searching firmware fro I9100G does gibe KIES but nothing for the Netherlands, so what to do?

  • Naveen

    I had the same problem with Galaxy S2. I tried with ODIN v3 and the above PIT file. Step 9 gave a failed result. I unplugged
    the mobile from laptop and removed the battery and inserted again. Now
    the mobile is not powering up at all. No recovery mode/download mode.
    Pls help.

  • fishy

    DONT do this if you have a GT-I9100 It WILL hard brick your phone, i did this, and i didnt notice it said for GT-I9100G (yes i know that was my mistake) So.. now im here with a hard bricked phone (its the PIT file that messes it up, and there is useally no need for a new PIT file)

  • Christian

    All I can say is thank you, My S2 is back up & running after a few days down! Thanks once again, I tried alot of nonsense but nothing worked, then stumbled upon this thread & boom.

  • Marek Marczyński

    Hard reset works for me!!! Thanks a lot!! Before boot problem I had installed original Samsung firmware.

  • Neven
