Help please! Kingo root and I killed my friends Galaxy S4. I have tried: Everything but soft reset safe mode etc. He will call me when home. I think it was caused by: Me.doh

Put the phone into download mode by holding Volume Down and the Power button. Then flash ODIN OS back onto the device. It was not Kingo Root that bricked your phone but probably instead a corrupted hardware issue. If the device is under warranty, your friend could bring it into the store where he purchased the device or his carrier and request they try to reflash it.

It switches off after showing the Samsung logo for 2 to 3 seconds?

When I switch on my phone it switches off automatically after displaying the Samsung logo for 2 to 3 seconds. The device is not even switching ON when I try it using the power button. Even the boot menu is not displayed.

The most common cause of this symptom is that the ON/OFF button is stuck. Sometimes tapping the button gently on a hard surface may free it up but in most cases it will be required to be replaced. Some people have managed to remove the button from the motherboard and started the phone by holding the home button and plugging in the charger then selecting reboot from the menu.

Did I break my Samsung 10.1 Note?

Well I clicked on permanent unroot in the SuperSU then went and did Reset from the settings so my Note is formatted, then it just keeps going on and off, and it shows the logo then goes off and does the same.

Something in the unrooting process has gone wrong, so you have to reflash your device. Head over to this tutorial and for the first step, download your own firmware for your country and carrier off this Web site.

Repeatedly locks on white screen with the world logo?

S4 keeps going to white screen with 'blue sphere/world' logo. Logo spins much more slowly than normal, and often stops. Difficult to get to home screen. Plugged in but battery is not charging much (I think the screen is rapidly draining the battery). Phone worked fine all day with little battery usage. I have not downloaded any apps in weeks. I have turned off and on, and turned off, taken out the battery, and held on button down for 3+ minutes to discharge any capacitors. I have tried: See my first message. I think it was caused by: No idea see original message

Check the bottom pin connection on the phone. You can use either a toothpick or pin to wiggle it into place. Your battery may be the culprit and one way to test is to purchase a new one or go to a phone repair store and ask to test out a battery. This also can happen when the charger fails. Those from the factory box chargers are not lifetime. Many burn out in just over a year.

My LG 3 showed a bright green screen then powered down?

My phone was not fully charged. In fact, the phone needed to be charged up. I looked at my phone and there was a bright green tint on the screen then the phone powered down. There was some very tiny "writing" on the face and I couldn't read what it said.. . help! I have some VERY IMPORTANT documents for an upcoming court case on this phone which haven't been backed up yet. Must I do a factory reset - and if so, won't it delete everything:? How can I save it the screen shots that I took ??. . Thanks for all your help!. . sheila

Install LG's PC Suite on your PC. Then connect your device and see if you can back up photos and other files. You may have just completely confused your phone for lack of a better description. Some devices go into a Power Saving Mode when they are low on battery. Connect your phone to a charger and wait until it is at 80% or higher before you attempt to turn it on to connect to the PC Suite.
