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.
Powering on a Samsung Galaxy SII without the power button:
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:
- Remove the battery and reinsert it.
- 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:
- When the recovery mode menu is displayed release the volume buttons.
- Press the down-volume key to restart the device.
- The phone should boot up to your lockscreen, and you’re good to go!
