Tips and Tricks – Powering on a Samsung Galaxy SII without a Power Button

Recently, I needed to recover some files from a T-Mobile Samsung Galaxy SII with a broken power button. There is a common problem with many Galaxy S II phones where the power button will either be stuck or unresponsive. If the power button is stuck, the phone will be difficult (if not impossible) to fully boot, as the phone will constantly shut itself of and reboot. If you’re looking to boot up your phone that has a similar problem continue reading!

If your phone is stuck in the rebooting loop, you’re going to need to disable the power button somehow. WARNING: Doing anything in this paragraph may void your warranty; do at your own risk. You may be able to mash the button enough to cause it to stop being stuck, but if that doesn’t help, you may need to take more drastic measures. If you don’t mind destroying the power button and possibly voiding your warranty you can easily open your phone and disable the button. First disassemble your phone and remove the mainboard (Instructions on disassembly can be found in plenty of YouTube videos, you only need to remove the mainboard). Then locate the power button switch and wiggle it until it disconnects.

If your phone is still powered on, you can plug it into a computer or charger via USB, which should wake it up so you can access your apps and files. If your phone is powered down or you still can’t get the phone to wake up, take the following steps:

  1. Remove the battery and reinsert it.
  2. While holding the up-volume and down-volume buttons, plug the phone into a charger or computer using a USB cable. This will boot the phone into recovery mode, shown below:

  1. i tried this and it didnt work. i just want it to turn on long enough for me to back my stuff onto my laptop so i can transfer everything into my replacement phone. any other suggestions for me?

  2. Thanks mate, but this boots into download mode. Is there a similar way to boot to recovery mode. I need to hard reset. and the power button is not available.

  3. It will not work for me… I have a verizon galaxy note 2, any other suggestions? I’m going to get it fixed, but the phone repair shop will not have the part for about a week. The phone works fine, just the power button will not work and it died today and I can’t turn it back on.
