I have some issues with my s4 a few weeks ago it started
first i couldnt change my brightness right after that my boot animation disappear and now i cant enter my recovery i found that out because today i tryed to delete everything and install new in hope that the bugs will go away but then this
i think i can go in to the recovery but my screen does not show it but i am not shure about that.
also after i tryed to install 5.1.0 android to maybe get in recovery, (befor i had 4.4.4 installed because i have a weird input lag in 5.1.0) i noticed that the screen is flickering but only in 5.1.0 in 4.4.4 i never had this
what i already tryed: install I9515XXU1ANK2_I9515YXY1ANL2_I9515XXU1ANK2_HOME.tar and I9515XXU1BPK3_I9515YXY1BPK2_I9515XXU1BPK3_HOME.tar ,
adb reboot to recovery , tryed to change kernel with app but i think that didnt worked
installed twrp, cmw both didnt worked
please help me to fix my phone
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

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!
Hi guys,
Something strange is happening to my zenfone. When I want to switch it off, and I click the "power off" option my phone activates offline mode, then the screen just dimms instead of going full black. When I try to switch it on again, everything is okay except that my phone doesn't vibrate and goes straight to boot animation, there is no loading system circle, phone boots up in 3 seconds. I don't need to enter pin too. When I choose restart option everything goes as normal. Any help is appreciated

Its a common issue.
Just wipe everything from bootloader, like system, data,cache, then flash recovery.img from .44 update and then reboot to recovery and sideload the .54/.540 update.
everything will be fixed.
Me and my friend faced the same issue about a year and a half ago,and this fixed the issue.
What does 'sideload' mean? Sorry I am new here :v
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.
Hi,
I have a Note 4 t-mobile that is "brick" right now. and I hope if anyone offer assistance.
It is running Android 6. Ever since the last upgrade the phone would freeze and reboot on its own. I fixed that problem by installing Wake Lock. After that it would still experience sluggish at time but the phone is still very much usable.
Lately, after watching a bit of streaming video the phone would slow down so much that a reboot is needed. But yesterday my last reboot turned my phone into a brick. After that reboot the phone rebooted itself to the download mode. So I took the battery out, waited for a few minutes and put the battery back in and started the phone. Instead of booting normally the phone displayed the message including "set warranty bit: recovery" and then followed by the flashing TWRP splash screen. By "flashing TWRP splash screen" I mean the TWRP splash screen ( with the TEAMWIN logo) would be shown on the screen for a second, then the screen black out for a couple of seconds, then the splash screen is back on for a second, and the screen black out for a couple of seconds, etc, and never successfully boot into TWRP recovery. I had left the flashing splash screen overnight and nothing changed. Connect the phone to my pc via usb and fastboot wouldn't recognize my phone when phone was flashing the TWRP splash screen. So I tried to flash TWRP again by starting my phone in download mode "volume down + power". When I connected my phone to my pc Odin recognized my phone. But when I tried to flash a custom recovery (TWRP or CWM) it seems the download started but never finished (on the phone I could see the progress bar started but never progress further).
Any suggestions would be greatly appreciated1
Additonal info
I just wanted to add that my phone is still running the stock ROM.
Problem solved
Problem solved. Once I used a different cable and the download process actually worked and I was able to flash stock ROM using Odin.
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.
