I just just updated to TWRP 2.3.2.1 flashed the 4.13 bootloader and flashed scroslers 4.2 rom, while Google Play was restoring my apps the screen started flickering and there was white noise coming out of the speaker and then the screen just went blank. The only way I can get it to power up is to plug in the USB cable, doing this it powers up on its own and boots in to the ROM and then in a minute or less I get a flickering screen and the unit shuts down again. I have tried to get into recovery and it always shuts down before recovery starts. Any ideas?
Edit: Got into recovery did a complete wipe again and reflashed the ROM but the N7 shut down again as soon as TWRP started installing the ROM.
Try the nexus 7 toolkit if you can get your nexus to be on the time you need to flash stock and after that see if it remains on. If not, lock up and get it fixed

I tried (clean) flashing a droid concepts build over on droid-hive a little while ago and everything went ok when flashing. I tapped reboot system in twrp and the screen went black and didn't boot. I can't get it to boot consistently either into the os or into fastboot. It'll occasionally let me into recovery and I tried restoring a backup and also just rebooting from recovery and it won't boot at all. When it is plugged up, it'll show the charging icon when I tap the power button like it does when the screen is off. I've tried everything I can think of. Any help would be appreciated. Thanks.
Edit - I finally got it into fastboot and I flashed the stock google image. Its working now.

Recently my HD2 has been acting up a little, it's running android (I've basically followed and installed everything on htchd2android.com/how-to/how-to-install-android-on-htc-hd2-android-4-0-4/), and yesterday would just show the green HTC logo for a second before turning off whenever I tried to boot it up.
I tried taking out the battery and sd card, put it back in to boot up, but this time the screen flashed yellow and white and went all glitchy for a few seconds, and ever since when I try to boot it it shows a glitched HTC logo and stays like that indefinitely.
(You can see what the screen looks like currently at i.imgur.com/42kYqkl.jpg)
I've tried reinstalling the custom rom, everything bar a factory reset (which will be my last resort), but really I just want to know what's caused or causing the problem.
Any advice appreciated!
Had the same problem yestrdy and i flash the rom again now its working fine.. but you wait for someone's solution i suggest if ur data is important

I tried to update my rooted LG G2 D802T to lollipop using lg pc suite and it all went well but when the update was completed my phone got stuck at the lg logo with the led shifting between green and blue color, when I turn phone off it automatically restarts and goes back to doing this, I waited for a whole day but the phone stayed like that, I can't enter download mode as it goes straight to fast boot and recovery won't work either. I don't have a custom recovery installed either. I'm kinda new to all the software flashing and stuff, pliss help
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
