Everytime I plug it into a charger it says is " this phone has been flashed with unauthorized software & is locked." And every time I press the power and volume button it goes to a black screen asking to boot in normal or recovery mode but none of them work it goes back to the white screen.
Is it hard bricked?

I am trying to restore the phone using a video on youtube: "How to Unbrick or Restore the LG G2 ATT Version"
The only problem is that after the phone was bricked it stays on. If I hold the power button on the power button until it turns off, it immediately reboots to the LG logo for 2 seconds and then it goes to a dark screen that is lit---thus the phone is clearly on but there is no image.
So I cannot boot the phone into download mode for this reason. For download mode, the phone must be off.
Help anyone?

HOld the power button, as soon as it turns off try the hard-key buttons for downlode mode, it worked for me. I faced the similar issue. if not just hold the downlode mode button while it is on, it should work.

Thank you !!!
I want to say thank you so very much for the INFO. I have an AT&T LG E980 cell, I left my cell plugged in on the charger because the Download said not to unplug until the download is completed, It was plugged up past 12hrs, so I unplugged it fear of overcharging, After a couple of hours, I began pressing the Volume down+Home+power buttons simultaneously and the Factory Rest Page appear, but when I press the power button to confirm the action this Code popped up:
18370
18370 Source :Boot Error! Cause boot certification verify
18370

Below it every time I repeat the steps. It want power up without being plugged -up. OMG!!! What Next?:crying:
i saw a shortcut like on the internet *#2663*#(don't remember exactly) and tried it. it showed my touch screen version.I accidentaly pressed the "update firmware" button.It said updating... do not turn off the phone.i waited for sometime but ended up removing the battery.now when i switch on my phone the touch screen does not respond.i switched of my phone and tried pressing the volume up+power+home button which shows "RAM DUMP mode (ARM9 mode)" and freezes in the Samsung screen.if I try pressing the volume down+home+power buttons it shows a yellow triangle with the android symbol and below it says downloading... and freezes. i don't know what to do now....please help me out!!!..
You should be extremely cautious not to press that update button. That kills the touch sensitivity.
Since u have done that & have access to download mode, I can only advice u to flash GT-S5670 stock firmware(froyo/gingerbread) by odin v4.38. That may help, atleast u can try it.
& when flashing is successful & still touch doesn't work then...I guess u have to visit Samsung care centre:sly:.
Please help me! I own a galaxy s6 (international model, official, not rooted) which is stuck in a boot loop from hell. The led is white (not the usual "boot-up blue") and won't change colour or even turn off. It was the last straw a few hours ago when it randomly restarted, got stuck halfway through the Samsung logo and started making the loudest noise I've ever heard it produce. It was NOT a vibration. Ever since then, it has just been stuck and keeps restarting. When it does get past the "Samsung Galaxy S6" screen it just says 'no command' with the android lying on its back. I'm at a complete and utter loss. It's actually done this a few times this week, but I've always been able to at least boot it into safe mode and uninstall snapchat - which I think is the cause of all this. I can't power off the device, and even when the battery drains completely, the same 'no command' screen appears as soon as it's plugged in. I can't boot it in recovery mode as I can't get it to switch off. I think it may be battery related or even motherboard related. I can't even seem to bypass the 'no command screen. It's just sitting on my floor, charging, overheating and looking all smug. Frankly, I'm pretty damn close to hurling it out of my window.
Also, does anyone know WHY the led is sometimes white or yellow during a boot loop on newer Samsung Phones?
Put the phone in download mode by holding Power + Home + Volume Down buttons. Plug in to Odin and Flash Official Firmware or use SmartSwitch

Thanks but I've tried this several times. The device seems to be completely unresponsive to all commands except a force restart (power key and volume down). I can't put it in download mode or even power it off
have u tried using smart switch emergency firmware recovery? power key and volume down should force it to power down, than enter download mode vol down + home + power key.

Whenever I use this combination of keys it just restarts and it doesn't even show up on Smart Switch when connected to my mac
if you are not be able to take your phone to download mode then repair center is the only solution.

Yeah. It looks like I have no other choice
It is a samsung S7 smg930f stock Rom from Brazil, did not suffer any damage at all, but does not turn on anymore.
Does not respond to Power Vol+ Home buttons.
After some time charging it enters the Green 'Downloading do not turn off target' Screen on its own,
then you can reset it with Power Vol+ Home buttons but the screen goes black again,
it does not enter the recovery menu.
When it enters Download Green Screen I connect it to windows 8 and it shows 'Serial Gadget' under device manager.
I suspect Samsung killed it with an update during the night. Is there anything I can do?
Thanks
Celso
