Don't know if it's related to root or unlock bootloader.
Yesterday I used toolkit v7 to root and unlock my GN. All went very well. This morning, when I pressed power button to wake up the phone, the unlock screen came up for less than 1 second then the phone turned black screen. I didn't even have chance to slide the bar to unlock it. 2nd time I was successively unlocking it by sliding extremely fast in less than 1 second, then the screen turned to black again. However, you still can feel vibration when you touched the black screen, meaning the phone was actually working.
What I found was I have to repeat below steps 5 to 7 times to finally have stable unlock screen
1. press power to wake up, unlock screen flashes for 1 second and the phone turns black screen immediately
2. press power to make it sleep mode (still in black screen)
3. repeat first step
Anyone has similar issue and solution to help?
I am still with stock rom 4.0.4, only unlock bootloader and root, nothing else.
Thanks so much for the help
It doesn't have anything to do with root and boot loader unlocking. I had this problem on 4.0.2 but it went away after I rebooted.

Thanks. I have been trying to reboot at least 10 times and the same unlock issue still exists.

Since I unlocked the bootloader and now have relocked it and gone back to stock rom... I seem to have serious issues with the screen. When I hit the power button to make the screen go to sleep, If I hit the Home key whilst the slider is closed it doesnt wake up, I have to remove the battery and restart the phone. The phone also does not boot whilst the slider is closed!?! Any one have any ideas?
I have a feeling it may be the flex cable but the phone was fine before I unlocked the bootloader!
Anyone can help me here?
Hey guys i was wondering if you guys know why my phone its not locking it self, what im saying is that every time that im not using the phone, the screen goes black like always does but when i press the unlock button the phone is in the main screen not the unlock screen mode. i have to press the button twice so that i can see the normal unlock screen. Is there something i need to change on my settings?
Im running Embryo 6.3 and did all the fixes and its running great. Just the unlock screen not working like it should
So I bought my wife a new Tab Pro 10.1 model. It started doing this immediately out of the box. Screen works fine for a while. After you lock the device and the screen shuts off, it won't come back on. When you unlock the device everything works, except the screen stays black. Digitizer works, you can swipe to unlock, hear unlock sounds, and even the backlight keys work. Screen just stays off. If you hold power and reboot, the samsung logo shows up and all is good again, until you lock the device. I performed a factory reset, and even played with all settings I could think of. I don't want to flash a custom ROM to see if that's it, as I might need to send it in. Any ideas?

Send it back. Definitely.
dear community
my neighbour gave me his Z1 compact because it did not work anymore.
It was stuck on loginscreen, when i touched the unlock button it vibrated, but nothing else happened.
I could however download all his photos on my Win7PC by just plugging it on USB
but it kept staying unresponsive, no way to get beyond lockscreen
So I used SonyMobileFlasher and unlocked the bootloader without any issues - no errors.
Then I flashed a new firmware obtained through XperiFirm without errors
Now, when I boot, I can hear the boot-melody (??)
but the screen stays dark.
I can connect the phone via flash mode and fastboot mode
I can switch it off by pressing volUp+Power (three vibrates)
from Off i press power, it plays the melody, but the screen stays dark
Is it a hardware damage?
Is there anything I can do for the phone?
thx for ur input

Seems like busted display to me. Flash recovery and see if touch screen works in recovery. If not, definitely hw.
thx for ur reply, i flashed TWRP- several trys, now I can see the TWRP lock screen, but when I swipe to log in it vibrates, soon after the screen scrambles away, vertical lines just fade and then crash-off.
seems very much like the screen is defect? not worth replacing, seems like a whole huzzle to replace that screen
pitty, one more device to trash.
i am seriously looking into fairphone2, would be nice to replace the screen so easy.

Maybe not extremely easy, but there are guides in the forum here for screen replacement, if your feel up to it.
my oneplus 3 (rooted) is not accepting my swipe pattern and does not give me the option to enter a pin code after a forgotten swipe pattern. i called oneplus but the person i spoke to said the only option was to wipe the phone. she would not allow me to talk directly to anyone with any technical expertise.
when i power on the phone everything seems normal until i get to the swipe pattern screen. first ,the bootloader screen (i think, the screen where you either press the start button to start the phone, or use the volume buttons to select options like poweroff/restart/recovery etc) shows up and then the oneplus logo comes up with the 'powered by android' at the bottom. then it shows the two white dots orbiting the red circle and then the screen to enter the swipe pattern appears with 'to start android, draw your pattern' at the top. i have made a few failed attempts, but it is now counting down, saying you have 6 attempts before the phone is wiped.
about two weeks ago i began having an issue that occurred maybe 2 or 3 times since. i would pull my phone out of my pocket and it would be powered off. after i turned it on, the initial swipe pattern would not be accepted, but the second swipe was always accepted.
i have tried entering recovery mode (teamwin), but the swipe pattern fails here also.
is there any way to get the phone started without losing my data?

Don't think you can do anything. Haven't encountered this what did you do with your phone? Are you on the latest TWRP? Latest OOS?

i had not changed anything on the phone recently. the swipe pattern has been the same since i got the phone over 2 years ago. i believe i was on the latest twrp, and i had a notification for about a week or two that there was an update available, but did not get around to downloading and installing it yet.
