Black screen on boot with T989 - Galaxy S II Q&A, Help & Troubleshooting

I'm running aokp jb on my phone. The other day I decided to change my boot animation so I used the tool in Settings to do so, then rebooted. However, after it got past the Samsung logo it was stuck on a black screen for about half a minute before the screen got brighter and the touch keys lit up, and it never boots into the OS. What's also strange is how I can feel the vibration of the pattern lock. I entered the pattern and heard the unlock sound. Is there any way that I could remove the boot animation and bring it back to the stock Aokp one, or do i need to reflash? Thanks.

Try wiping cache... !

blinking blue led!?

I'm running gingerblur 3.5 an my wifi occasionally fails but a quick reboot usually fixes it..... but this time a reboot got me stuck on a boot loop.... after 3 boot loops the phone started up but there's a blue led flashing!? It may be worth mentioning that the led only flashes when the screen is awake and i'm unable to reach the lock screen. Locking the phone puts the phone to sleep but the lock screen isn't appearing!? I'm not using and have not used any led notification apps.
So i got the lock screen back by putting a password on it then removing it but i just noticed wifi is definitely broken i guess i'll restore with tenfar's recovery

Are you connected to something by Bluetooth and you happen to be out of range when it flashes blue?

no, bluetooth is off but i plugged the phone into the charger the led turned green then when i unplugged it the blue led was off. Then a few reboots later wifi is up and running. I will be happy when the devs get an AOSP rom running on this thing.

Weird Crash

Ok So my TFP starts out of the blue rebooting on me from time to time. and then i had to reboot it like 3 times or more to get it to where when i slide to unlock that it would actually unlock instead of have the lock circle on the unlock but never go any place then it would reboot by itself. i got stuck in a loop where no matter how many times i rebooted it got stuck on lock screen and rebooted. so i hit the reset button and jumped in 5.8.2.0 and restored from a back up. it booted up but i noticed that i my home key and setting from the right side did not work. and the lock screen does not come up any more when i turn on and off the device. Anyone have this problem? seems no matter what rom ive tried same results. lock screen no longer comes up right side quick setting no longer work. i did wipe everything before flashing. also for a side not tried to restore to stock image from my backup and got error while it was trying to put the data folder back. ive always used the 5.8.2.0 so not sure what the hell is going on. Any help would be appreciated. Almost feels like there is a problem with my primes memory.

[Q] Sola lockscreen problem

Most of the times i try to unlock my phone, the screen flickers, then the lock screen shows up for about a second, then the screen turns black, but the phone stays unlocked.When i try to unlock it again it happens again for at least a few times.I tried installing different roms, but it doesn't help.This was happening with the original rom too.

[Q] S2 screen won't wake it just flickers and goes black

My S2 boots up fine (screen very bright and animation color not natural) after finishing boot the soft keys lights up but the screen goes black. When i press the home button the screen just flickers, shows the screen for a split second then goes black.Sometimes after many attempts pressing the power button it wakes but screen at full brightness and color is not natural. When i try to press the screen brightness to adjust it goes black immediately.
What i have tried so far, bought a new LCD screen and replace but problem persists. So its not a LCD problem. It was running stock ICS so i flash stock JB after wiping, no help. Root with Philz kernel but when i go to recovery screen goes black so i try Speedmod kernel with CWM recovery and the screen shows the Recovery menu I try to flash a custom rom (can't remember which one) but it won't boot up stuck at splash screen.I even flash GB and ICS stock still no luck.
The phone works fine calls can still get through, download mode screen and recovery screen ok. I actually have not use this phone for a year but the last time i use use it was working fine.
Google all the different Samsung device if anyone has this problem but no one seem to have the problem that i have so maybe if anyone knows or suggest anything else which i haven't tried.
Thanks for viewing
I have found the root of my problem, the damn brightness control in settings is not working. Brightness is at full, unable to set to auto or manually dim the screen.
Screen will only wake with black background. Have to tear apart the phone and figure whats wrong

[Q] Black screen on boot

Hi there,
I've been a lurker of xda for a while, but I have a question that I haven't been able to resolve since googling for about two hours or so.
I have a Nexus 5 on stock 5.1, rooted.
I changed my bootanimation.zip, and in the second stage of booting, where normally the stock boot animation changes brightness, the screen goes black. How can I make it so that the bootanimation keeps going until my phone is ready to run, and it reaches the unlock screen?
This is my first post so please excuse me if I've done anything wrong.
