Hi, I changed my screen resolution and all of a sudden the whole screen went black. I can still access recovery and I can still see the power menu when I leave power pressed and the screen responds to me clicking the button to restart etc. I can also flash through recovery. I dirty flashed a newer version of the ROM and I could see the system dialogue box telling me the system apps were updating, but from then it all went black. What should I do?
Fixed it by flashing an updated version of the same rom then flashing back to previous rom and then flashing back to the updated version.

Hi Guys
When I turn my phone on, after the Galaxy S first screen, the screen is multi-colored for about 1 second before going to the boot animation. Once the boot animation appears the screen is fine.
That's not a problem. What is a problem is booting into recovery, the top of the screen has a few blue lines. It still operates as if it is in recovery, as if I press the power button it reboots - but if I press down once, then power, it's not rebooting. So it looks like it's just the screen can't display what's being sent to it. So I can't do anything in Recovery like installing the auto-phone record, screen capture service or extended power menu. It will also be a problem if I come to install another ROM.
Does anyone know why? It started happening after I flashed a new ROM - I flashed the new ROM because the phone was constantly freezing when running certain apps (and needed the battery removed to restart the phone) - it's no longer freezing.
thanks
I'm not sure but,i think it because you don't have the good bootloader.For example,if you flash a rom from Froyo to gingerbread,you need to choose a rom with the gingerbread sbl(bootloader) include.
So to avoid this problem,just re-flash the entire rom with boot loader included.

thanks I'll try that
I am one of the many Droid Pro users that did not receive the Gingerbread update before Verizon pulled the OTA update. I decided tonight that I would try to update with an update.zip file using the recovery method. The install appeared to be going well right up until the end. At around 90% or so the update failed and abandoned the update, I selected to restore the original firmware and restarted the phone. The phone restarted and this time the Motorola icon had changed from the normal white icon to a red icon, I'm assuming that something changed. The phone then went black, power still applied to the screen but just black. I could hear the phone starting up as it made its characteristic DROID noise and the keyboard and screen buttons illuminated, however nothing shows up on the screen, it still remains black.
I have tried numerous methods to reset or restore but I am unable to get anything to display on the screen other than the red icon as the device powers up. Any help would be greatly appreciated.
should flash the stock firmware.
Hi,
I have a N4 that was new but the screen cracked on it and eventually the battery died as well (wouldent hold a charge). I got the battery and screen replaced but as soon as this happened I could not boot into any rom. I had twrp installed but everytime I tried to install a rom such as CM it would install but would stay stuck in the boot loader. I then used NRT to try and kick it out of bootloader and I tried several different stock firmwares, 5.01, 4.4.4, and 4.2. The only rom that was able to get past the boot animation was 4.2 it went to the welcome screen to choose a language but I could not select anything via touch screen. In that screen I could lower and raise the volume via the rockers and turn the screen on and off. I had twrp installed and the touchscreen worked fine in twrp. I also tried this: http://forum.xda-developers.com/nexus-4/general/tutorial-how-to-unbrick-n4-t2347060 and it also let me get into the developer firmware but of course it is encrypted so I could do nothing. The phone has not had contact with water etc. Do I have any other options? Can I get some type of diagnostic such as logcat or something?
Thanks!
So this happened when I installed latest version of LOS14.1.
Basically happened to me 3 times, the screen won't turn on after I lock my phone, reboot doesn't help and there is no logo on boot. Black screen in recovery and download mode. I managed to enter download mode and installed stock firmware but the phone screen is still black.
When it first happened I managed to 'repair' the screen by pressing power button for some time. Second time it happened I got lucky again and screen turned on so I did factory reset. This time I can't do anything, I flashed the stock firmware and the screen is still black with blue LED on. I'm out of options and have no idea what to do, I am going to open my phone tomorrow to check if some cables loosened up.

Does the phone boot properly to the desktop after flashing the latest stock ROM?
yes it boots normal
btw little update i found out i can use my recovery my screen just dont show any thing
i found that out because everytime i was downgrading from 5.1.0 to 4.4.2 i had to do wipe data or it wont boot
i tryed to go in recovery and go 3 down (wipe data) and then 7 down (yes) just with youtube videos and it worked before the wipe my phone does not start on 4.4.2
that means that my recovery is working but screen just doesnt show it
it doesnt show anything but the white samsung logo, normal system, downloadmode
at any other time my display ist blank
as an example when i turn it on i see the white logo then screen turns blank i hear the bootup sound, after 15 sec screen goes black and when i press unlock i can normal use the phone
but why is it blank while booting and in recovery and also is a bit flickering when phone is turned on normal
Recovery works on stock lollipop?
yes recovery works but screen does not when i enter it
the screen is turned on but it only shows black
same thing when the phone boots up screen in turned on but only shows black untill the phone is booted then screen works but is flickring a tiny bit
i called in a repair shop they told me maybe the backlight control is broken???
because i also cant change my brightness its set to max and doesent get darker when i move the slider
