Yesterday I've update my CM on my Nexus 4.
During update, my n4 restart and get in bootloop ( see google logo, after that Display starts to blink bright and dark)
I can get into fastboot mode, but if I choose recovery mode, same problem appears. (google logo, after that display starts to blink bright and dark.
Anyone idea what I can do?
Thanks
Try reflashing a stock rom.

Then I turn on the phone google logo appears, stays for few secs then phone turn offs, after a sec it turns on again with a google logo and it goes like this infinitely. I can't get into recovery, because the same happens if i click Recovery in fastboot. It fixes after charging the battery a bit, probably my battery was dead before, but today I fully charged phone, tried to root my phone so I unlocked bootloader and when I needed to factory data reset, in recovery mode i got red triangle, I turned the phone on and off and got this bootloop again.
Any ideas on how to fix?
EDIT: Finally i turned it on, rooted the phone installed franco kernel, hybryd radio, and ParanoidAndroid, with bad gapps, reinstalled good gapps and now the phone does it again, except it doesnt restart, just freezes at google logo screen
After bootloader is unlocked flash a custom recovery through fastboot, boot to new recovery, wipe all, flash ROM of choice
If this doesn't work then wipe all in fastboot and flash ROM through fastboot, but a working recovery is nice to have

HI
I have managed to flash in flashmode the recovery file and other that was mention in other post successfully on windows 8
did Fastboot Reboot and phone rebotted to android bot with progress green bar under him then went to lit black screen with green strobe light that lights up and dims out .
I can use power plus volume down and then press power twice but this just shows android bot and goes to black screen again
I have flash uk open d802 kdz file but still fails at 49%.
I can not access recovery at all and don't seem to get back into fastboot mode.
any help would be great been stuck for days .
don't want to take it into the shop to be fixed if I can do it for free.
anybody got any good ideas would be great . I am new to all this and some times don't understand certain things .
Hello I am trying to fix a friend nexus 7 first gen
the problem is that it keeps flashing the white google logo like its boot looping , the system doesn't even seem to be restarting just a flash on flash off google logo , no nexus logo or anything else at all.
I cannot get into recovery it will just shutoff everytime i try even from the bootloader menu
tablet doesn't have debugging mode on so only thing I can do is work via fastboot
already tried to flash like 5 different versions of android and everytime it finish (succesfully) and goes to restart it just keep doing the same on the google screen.
any help is greatly appriciated, and I have been searching all around the internet for hours now and have seen many solutions to bootlooping which I have pratice before on many of my other android devices but nothing like this problem.
thank you and pardon my english.
When you turn on the tablet with the power button and the screen's backlit turns up, press the VolDown button. This way you can boot into bootloader and flash a factory image provided by Google.
yup like I said before I did got into bootloader and flashed factory stock images like 10 times now and still having the same problem, this is what i usually do when I get into bootloops with any other android device but for some reason this time is different.
its not idle at google and I dont even get to see the nexus logo it just shows the google logo for one second and screen goes black then again the google logo and black screen like infinite restarts with one second delay.
Then it maybe hardware related (corrupted nand/partition/etc) so you might consider to send it to Asus/Google to repair.
I wanted to update my mothers P8 lite, but somehow the update failed. it doesn't show the logo anymore when it boots. Now it shows a black screen with stripes, it even shows stripes when I boot to fastboot or even recovery. I wonder if something is wrong with the display driver. But the phone seems to work when its boots to the system. I can hear the volume sounds when I press the buttons, only the screen is still black with white stripes. I wonder if something is wrong with the display driver.
I tried to use the huaweiextractiontool and flash the individual img. files trough fastboot of different firmwares. Exept the the display the phone seems to work normally I can still boot into fastboot, and I hear the sound when booting. But its the still a black screen with stripes, and every frimware gives a different stripe pattern.
Any idea on how to fix this?
Greetings.
Problem solved
I solved the problem by flashing agian the last working firmware. And My mashing the volume buttons agian, it booted in recovery and the screen is restored agian.
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
