Hi,
So my missus dropped her tablet (again) and this time she managed to smash the digitzer. So I went to replace it along with a new screen...
6 months later I get around to changing the parts. I reassemble and try to fire it up.
The Google logo flashes up and stay for about 2-3 sec and the disappears. Then nothing happens.
I tried plugging it in for 10 hrs and retried. No luck.
I can boot into the boot loader and the buttons work.
When I "power off" the device, suprise, it shuts down, on power up the logo flashes again and nothing.
Next I try "start" logo flash and nothing
When I tried Recovery the same again, then after about 60 sec it flashed the funny colored Nexus logo (very quick flash) then nothing again
When I select "Reboot Bootloader" it restarts the boot loader.
I'v been crawling the internet for hours now and have only found repeated attempts of loading the bootloader and trying recovery mode.
I did connect the tablet to the pc for a minute and could see a file structure but haven't been able to do that again.
Can someone please help.
Thanks
Matt
I'm beginning to think that the memory with the os has been lost, I might try unlocking the boatloader and refreshing the oem Rom. Any thoughts?

So I unlocked the bootloader and flashed the newest stock rom to the tablet and still wont boot.
Same as before, Google flashes up and then black screen.
So, I figured it out. It was working the whole time, only the backlight went off after the Google logo disappeared. Its not the brightness sensor as its reading correctly in GPS status. It seams to be a software issue.
I've set the brightness to a fixed level and it is working OK, when I set it back to auto adjust it turns the backlight off again, when I shine a torch on the sensor I goes bright again.

I am having the same problem as you have described above. After changing the digitizer/ lcd, the tablet boots up and google logo shows up for few seconds and the screen goes blank. It goes into recovery fine. How did you fix it?
Turns out it's the lux sensor. Turn it on wait for the Google logo to disappear and grab a bright torch and hold it over the lux sensor it's right beside the camera the screen should go bright once it gets to the lock screen. If not use the torch to see what's on the display and once you've unlocked the tablet set the brightness to constantly on full instead of automatic brightness and this will override the lux sensor.

Thank you so much. I followed your suggestions and now Nexus 7 is back up and running.
But I am afraid of rebooting it because I wasn't able to replicate your instructions once I had to reboot for system update. I had to flash factory image through fastboot and had to redo the initial setup and then the screen turned on welcome screen. So, it is hit and miss. Sometimes screen does turn on after few minutes of booting and sometimes it takes several hours for the screen to turn on.
I have my screen brightness setup to full. Will this override the lux sensor permanently or only until the next reboot? What is your experience with the tablet since you discovered this solution? Again, thank you so much for your help. I almost gave up on it and was ready to trash it.
Setting it to full with auto off should kick in after boot. When mine boots up it doesn't show the swirling dots but once it's done loading it pops up with the lock screen. I read somewhere that YouTube overrides the brightness setting and defaults back to using the lux sensor. I downloaded and paid for lux auto brightness that can override all app brightness settings permanently and it worked a charm for me. Maybe give to lite version a go and see how you get on.

Thanks, just downloaded Lux Auto Brightness. Will see how it goes.
LG G2 rear LED won't turn off. It stays on all the time. The only time it turns off is when I turn off the phone.
I have been using this phone for 3 days and then this problem occurred. It takes a toll on the battery as well.
I have tried turning off the notification LED from display menu and it still stays on. Tried using some apps to turn off the rear LED but no success.
Is anyone else facing this problem? Can anyone suggest solutions for this?
Thank u.
I'm facing this problem as well,
Have you get the solution yet?
That's a strange glitch. The notification led switch is located under both display and accessibility menus. Try switching off one and then the other(they both have the same function and are connected so if you switch off one, the other does as well). If you are 100% stock then all you can do is factory reset and make sure you're updated. If you're rooted and autorec you have more options.
Hi everyone,
I have an unrooted Galaxy note 3 device (India). Since a week the notification led has stopped working. Now the LED does not glow at all for any of the events like charging, sms, and other notifications. I tried searching this issue in the forums but could not find such issue in any of them so i have created a new thread.
Has any of you faced a similar issue? what can be the problem and what can be the fix for it?
-Regards
Nikesh
On dialer, press *#0*#, then LED from the menu.
What happens?
It shows RED (in red)
after tapping again, it shows GREEN, then BLUE and finally END
Not a hardware problem then.. Have you tried a 3rd party LED app, e.g Light Manager?
No i havnt tried any third party app.
Try flashing the LED drivers..
Hey guys I'm not able to use blue led notification on my s3 neo other colours like green and red works fine for notifications the blue led doesn't work I tried it even on the HW test module *#0*# what shall I do please help
if other colors work then its probably not a hardware problem.
silly question but did you switch it on in settings > led indicator > notifications? Note that the led only works when screen is off, unless using market apps.
That was really a silly question but anyways thanks
I tried flashing the firmware bit still it doesn't work
If a fresh install did not work, try light flow or led blinker from market to see if you get the results your looking for. If you get the blue color when using the apps then you could assume that the problem is not a hardware but may be in your rom or maybe a app you installed.
While I certainly enjoy not having the menu navigation bar visible at times after the latest update my LED indicator light stopped working I verified in settings that it is in fact on but still no luck anybody else
