i have and i tried all of the manual button combos to bring me to the recovery screen and all have failed so far

Place the phone in upgrade mode and use the offline flash. But if you made cwm backup then just flash that.

is there a manual button combo to bring it to that becuase i cant get past boot animation

You'll need to turn off the phone. Then while holding volume up, plug in the phone to the computer. Upgrade mode should pop up.

Chainfire 3D BLACK SCREEN!!

I was messing with the nightmode and accidentally turned the sliders to ZERO. My screen is BLACK and I cannot get out of it!!! I'm rooted, cannot get adb to work or get in to recovery. I've tried holding home + volup + power and recovery will not work. How can I fix this!!?
If I can just get in to recovery I have a recent backup I can restore.

When you power up, do you see anything?
Pull the battery and then once you put it back in, hold down Vol up and down along with Power until you see the logo come up. Let go of all 3 buttons. You should then be in CWM shortly.

If you reinstall the Chainfire Driver the screen will go black again I discovered that the hard way. You need to edit the persist.cf4d.nightmode file located in /data/property . If your screen is all black the file properties are set for 0 0 0 and you need to change all the 0's to 255.
I acidently messed up with the chainfire 3d plugin and its now in night mode and the screen is totally black . Reboot wont work and uninstalling the program from adb too as it says permission denied.Some posts here in xda didn't help everytime it needed the permission.Is there a method to uninstall this program from adb?

Did u read the fix listed above? Just boot into CWM and restore a nandroid backup. Or wipe and install a new ROM. I don't use that app so I hope it gets u back up and running.

Just read my comment that I had placed there. It will work, I had the same issue and I got it resolved that way.

Bricked or not?

Hi there, well, I wanted to install ICS, & I used this guide, & when i installed CM7 first, it restarted like it should during installation, but i get a bootloop. So, now, I can't access "Download mode" nor, the CWM recovery screen. Even when i hold VolUP & Down+Power, & it would go straight to the animation. I was going to install this http://forum.xda-developers.com/showthread.php?t=1502830 Any clue what to do?
Odin back to stock and do it all over

What bootloaders do you have installed? The key combo to get into recovery changes if you are on GB bl's.
From the guide:
Scroll down to "Install from SD Card" and scroll down to your ICS folder. Find your CM7 file and hit it. Once it finishes, reboot. It will probably bootloop. This is normal. Pull your battery and boot into (red or green) recovery again, "Install from SD" and reflash CM7.

Get back into recovery per the key combo for your bootloader and reflash CM7 over itself again. One this also to remember is that when you see the Vibrant pop up, take your finger OFF the power button when doing the key combo. Sometimes this is forgotten while in panic mode.
Well, uh, just saying, my nephew the other day was slobbing on my usb port, & now, the only time i can turn it on is when i plug in the usb. but, now, when i do that, usually when u plug it in, when its off, the battery bar would come up. Right? Well, for my phone, it seems like, the battery would come up, but it would be a loading bar stuck @ it, & I can't access anything. Is that normal for the bootloop ?

Stuck Booting to Rom Manager Recovery

I'm the stock att rom on 2.3.4. I had my phone for a while but never backed up my ROM. I performed a permissions fix and rebooted. I selected backup ROM and it rebooted. The phone tried to reboot but got stuck trying to boot to recovery menu. I hit the volume button and got the Rom M. recovery menu. None of the options work. It just shows an icon and does nothing. If I hit the volume button it goes back to menu. I've tried to reboot several times and it keeps on booting to a non functional Rom Manager menu.
I'm done my searches and I'm no luck. Is there a way to recovery without completely wiping the phone? I'm hoping there's an easy way to recover the boot using Odin?
Here's exactly what I did in that situation .. take the battery out and leave it out for about 2 hours.. this will totally deplete your phone of any kind of power.. after your done put it back in and it should boot up perfectly! If not try to take it out for longer

Depending on which version of cwm you are booting into...what button are you using to select? Most of them its either power or the home button. Try the home button to select.

Thanks for the response but I don't see how this would fix the problem as it boots from internal storage and not the memory. I'll try it while I'm doing research and waiting for more responses.

Much Thanks!!!!! Karashta. Selecting the home bottom to select instead of the power is the proper way of selecting the menu's.
Thanks for making my day.

No problem man. That freaked me out coming from my captivate where power was select. Glad I could help

GS2 wont boot passed recovery

Hi guys,
Late last year i sold my GS2 to a guy at work. Rooted and with a custom ROM installed (Cognition V1.5.1 - yes i know its old but its not my phone )
I've attempted to install RC1 for CM9 this morning however, I'm falling at the first hurdle. I've booted into Clockwork recovery (4.0.0.2). The menu buttons work fine i.e, up/down and power as enter but when i select anything it goes to a black screen with the ROM Manager logo on it (the gog and the hat) - but no options.
Do i need to install a newer version of Clockwork on the device? If i do whats the best way to do it? Do i use ROM Manager to update it as i cant access any of the menus in recovery (other than the top menu)
I've not seen this problem before as normally people are kept in boot loops or cant get passed a splash screen.
EDIT - i've just managed to get the phone to boot and its now running as normal. I'm just concerned that if i go back into recovery i might not get it back up again.
Many thanks

You're pressing the wrong button lol... use the power button to confirm and the volume buttons to move up and down. The home button does nothing.

[Q] Is my phone rooted?

I thought I rooted my phone - process seem to work OK and Superuser appeared in the apps list
Dragged a new Rom zip file onto my phone
Pressed: Power + Vol+ + Vol-

Should it come up with a menu?

Simply rooting will not allow you to flash a rom, you also need to have an unlocked bootloader.
