Screen goes black after boot .Tried several roms all with same result - ZenFone 2 Q&A, Help & Troubleshooting

I have a asus zenfone 2 (ml550/a008) .The phone worked fine till 2 weeks ago and then suddenly got stuck in safe mode with no access to settings or dialer.
I tried to factory reset and reinstall latest firmware but had the phone start only in safe mode.
I then installed unlocked bootloader, twrp and cyanogenmod latest nightly. The installation went fine and cyanogenmod booted till the first screen to choose language and then the screen completely went black.
I tehn went and reinstalled bliss rom for the same fone . Once again it installed perfectly but then went on to show a black screen when I went into settings or screen. The touch screen gives a haptic feedback suggesting that it is responsive
I am completely at a loss as to how to resolve this.
Please help!!!!!!!

Try rerepartion and reflash it again, see if the problem persists
Just boot in recovery and restore to factory
Simple.
Weird, I thought I had a working flash (been running for a couple days now) but I turned on compatability mode in settings and restarted.... black screen and 1 - 3 vibration pattern, WTF! Factory reset didn't fix it either, reflashing now :/
I had the same problem and someone posted from another thread that its the samsung task manager updated version 1.14 that is causing the problem. Wiped my phone, installed and updated all my apps except samsung task manager, rebooted my phone and all went well.
Edit: thanks to duracellbunny for finding the app that causing the problem.

thanks guys..... working now as mentioned above did not install task manger .
phone rebooting fine as mentioned at start it does work after a factory rest/cache but I always updated all that apps after a factory reset...... this is the problem as I apdate the taskmanager app and this has been the problem
thanks to antz88c for the post duracellbunny for finding the fault...
same here thats actually the last straw that gets me to downgrade to 2.1. I beileve its the samsung app that causes it. factory reset fixes it
Updating Task Manager from Samsung Apps causes this issue.Don't update this app!

[Q] HTC Desire HD boots but black screen afterwards

So I have a rooted HTC desire HD with Jellytime on it. All was working great till recently when it would shut down by itself. Today after I wanted to test a new boot screen from Rom toolkit I restarted it and while the boot screen worked great after it finished I see a black screen (backlit so I know its on). I tried going to the bootloader but after I try to go to wipe cache for example it restarts by itself and it gets stuck after the boot screen... Any ideas?
ok an update seems that if I go to the recovery via down button and power it lets me do actions. All this time I went to recovery mode when phone was shut down and plugged into a power source. I did a wipe cache and now it says android is upgrading and now it finished saying starting apps. Hope it didnt get stuck there because it keeps doin the cycle animation but doesn't do anything else.. I ll leave it be for a bit like this... :/ Had to restart it by removing the battery after 20 minutes... same problem as before still...
another update... just before it goes to a black screen when the boot screen finishes an orange light appears just briefly (where the green light appears when it charges)

I flashed the rom again and wiped data and all seem to be ok now. I ll update this because I saw many people have similar problems... thanks in advance for any help!
Have the same problem.
I bought this with the problem that it keeps rebooting all the time.
I unlock the bootloader with htcdev,root with Easy Ace Tool,flashed the new cyanogenmod 11,
but did the same .
At least 3-4 rebooting before open normally.
I said that it must be ROM issue and flashed the KK-LegacyCarbon-4.4.
Did the things should be...flash the ROM and then the boo.img separately.
Now i have black screen and the only screen i am able to get is bootloader and the recovery 4EXT.
I reflased cyanogenmod back but nothing happened,any thoughts???

Stuck on CM restart screen

Hi all,
I just rooted my G Pad on 4.2.2 and installed CWM 6.0.5.1, and then flashed the latest CM12 from their website. Now I'm stuck on the blue android loading screen. I've tried to get back into recovery, but I can't seem to boot into it with the key presses. It will show me the factory reset screen and then just tries to restart again. Any ideas on how to proceed from here?
EDIT: Was able to get into download mode and reflash stock 4.2. nothing to see here

Galaxy note 2 stuck in Teamwin screen after Encryption Unsuccessful....help

Hi guys, hope you can help me I`ve tried everything I can.
Following a mishap yesterday, my Note 2 which was successfully running Resurrection Remix Android 5.1 for the past 6 months has now been bricked, i think is the term.
My son accidentally updated the RR5.1 to a newer version then the phone went low batt. I restarted the phone and got the message Encryption Unsuccessful --> Reset your phone, which i did. (I read somewhere afterwards that it might have been a mistake to hit reset.)
Now my phone is stuck in Teamwin screen mode which is flashing and it does nothing. I restarted the phone into Android Odin mode, Vol- + Home + Power button and it says "Downloading.... Do not turn off target!!" which has been now showing on my phone for more than 5 hours.
To top this wee problem, since I could use Odin on my laptop to mount a Teamwin Loader and flash a new ClockworkMod 5.1.1 OS on it which I have BUT...............and heres the big BUT.....
None of my USB ports recognize my phone, installed 2 versions of the Samsung USB drivers and still nothing. So WHAT can I do other than what I already have been doing.
And a reminder before anyone tells me to enter this and that on my keypad...... PHONE STUCK IN ODIN and TEAMWIN splash screen.
Cheers and hope someone gets back to me,
