Need Help, Black screen no boot.

I am new to the android world, I have a vibrant that I rooted using the update.zip method. Then I went to apply the LAG FIX using the same method from the RyanZA thread. Now all I get is a boot sound and a black screen along with the buttons on the bottom glowing. I have no Idea where to even begin to recover this. I have a mac, any suggestions would be helpful. Thank you in advance!

That's a boot loop. In your case, being new and all, it might be better to re-install the ROM and try again. You might need to give it a while as well, I don't know the details of the zip you used, but it might be copying large amounts of data, which will look like a stall in the boot process.
Get ADB and open a terminal window and do "adb logcat" it should let you know where you are stuck in the boot. Post the log and someone here should be able to help you.
Also, get boot camp and/or Virtualbox going so you can use Odin, which requires Windows. If you mess something up, you can use Odin to get back to a stock setup. Sucks that it requires Windows, but that's just how it is for now.

Oppps mis-read this phone is complete black no noise just heat

Moved your thread to general section.

Had the same problem when I tried to install that FixLag update.zip. Lucky for me, I did an Anroid Backup before I attempt it.
Hold down Vol+ & Vol- and power it up, do a Wipe.. when its done, restart your phone. When its booting up, its gonna act the same without the Tmobile Flash and still missing the Samsung Galaxy S logo. Just wait for your phone to VIBRATE. Then your phone should be working. I dont know what happen in that update.zip but it deleted the Graphic at the beginning when you first boot up your phone. After that I went back and did a Recovery and got everything back too normal.

It worked!! Thank you so much! I am back up and running. No boot screens, however funtional and root maintained. Is there a way to recover the boot screens?

I was just searching through the forums for the answer to the last post in this thread - "is there a way to reinstall the boot animation? Well, is there? Mind, I DO NOT want the horrible tmo portion, just the S.
Thought?

I just did this to my phone like the ones stated above..... Blank screen then vibrate and im in the Android OS and it changed the Audio but still no graphics....... Kinda disapointing but until someone finds hwo to actually finx this I'm stuck.

Can't boot, tried flashtool, not going well, help

So heres my issue, ATT G2. Installed clean rom xe 1.1 then was dumb and used titanium to restore my app data, not system, just app. but someone that caused a system ui to keep crashing, so I got into recovery mode by holding down and power button (white screen that asks to reset to factory). Did that and it booted to TWRP ran a script and then went back to LG screen and then blank screen with flashing led and that's where it stayed, won't go any further.
I've put it in download mode now and am using LG flash tool but when I plug the phone in the box for COM41 in the flash tool just says waiting for connection and thats it. then when I unplug it it says failed, obviously. Is my phone a brick or can it be saved?

I think it's getting a model information check fail in lg flashtool, ugh this sucks.

LOL, i just went through the same thing. I'll be posting a fix tonight I worked out with Scott.
"There is a "back door" method. This is why they updated TWRP by the way...
Download this: https://dl.dropboxusercontent.com/u/...with cmd.zip
Extract it to desktop. open the command.bat file.
Type "adb reboot recovery" then press enter. You need to keep doing this during the factory reset.
This assumes you have drivers installed. If you have no drivers installed for recovery mode then just select generic Google Nexus ADB drivers.
You kinda have to hammer the reboot recovery command. Its all timing... To hammer it... press the up arrow in the dos prompt and that will repeat the line. then press enter.
Keep doing it until you see it reboot to twrp and you should be able to sideload or load from storage.
It may take 10 or 15 minutes to get the exact right timing so dont give up.
And of course, this is all dependent upon you having the drivers already installed."
- Scott
For timing, you'll need to wait right when TWRP starts writing the script and start hammering it out. Timing is everything so when you see the TWRP screen starting hitting the up cursor and enter. It should load recovery. Don't bother using the tool, it won't work as it thinks your device is a D802 and won't be compatible with the dll. This will get you back to normal and from here you can just wipe and reinstall the rom again fresh with out losing media/data on the your drive.

I haven't tested it on VZW unfortunately. Check with scrosler. However, I assume it should be similar if not the same, but don't quote me on that.
Updated Link guys: https://www.dropbox.com/s/qsjwguwtlyczwdh/adb with cmd.zip

so I got it right when it said teamwin to reboot but everytime it reboot it tried to run the script and would never actually go into twrp. att is sending me a new phone but I'm worried when I send this one back they'll get me for being rooted.

The minute you see the twrp screen pop up start hammering away at the adb command listed before. after you type it once, you can keep pressing the up cursor and it will just replicate the previous command. You are opening up the cmd in the adb folder right?

yeah just tried it again and as soon as I hit it it starts rebooting again goes to TeamWin screen and then runs the same script I posted before and when it is done it reboots and then goes to blank screen. I had just put the latest twrp on the day before too so I don't understand why it isn't booting to it.
My biggest thing is will ATT freak and send the phone back once they get it and go to download mode and see it says rooted or if they try the hard reset and see it goes to a TeamWin screen.
side note, if I can type adb shell and get it to prompt me there, is there anything I can try and type quickly to have it do anything else?

I did it a bunch of times continuously and it would just keep rebooting. Am I supposed to just keep doing that for 10-15min straight? How will I know if it gets into recovery if it just keeps rebooting when ever I keep doing that?

Keep doing it, watch your phone as it will eventually boot into recovery itself without running script.

like 5-10 min at most. it's literally timing. and based on what i saw on the youtube video you were having the exact same problem. btw, you have your drivers installed correctly right? you can check that under device manager. BTW, are you using a PC or mac?

[Q] Verizon G2 Stuck in Bootloop

Hey Everyone, just got my G2 today and already have a problem. So naturally the first thing I did was root it, and after a few hours researching the nuances of doing that on a VZW model I got that to work. Next I went and downloaded Titanium and moved my backup files onto the phone, and restored my apps no problem. Then I went to restore my system info (just call logs, sms/mms, bluetooth pairings) and rebooted the phone only to get stuck in a bootloop (the VZW animation would just play over and over.) So I powered off the phone thinking something just went wrong with the reboot. When I went to turn it back on I started to get worried...
No matter what key combo I pressed I could not get the phone to power on. I decided to plug it in and thankfully it did come back on, but once again went into the bootloop. So I did some researching and tried every way to reflash the stock VZW firmware, but nothing has worked. I tried the KDZ method mentioned here, but I cannot get the B2CAppSetup.exe program to install (looks like LG has moved or revoked access to csmg.lgmobile.com:9002). So I moved to this post, but I cannot get the LG Flash Tool to start the flashing (when as instructed I unplug the phone and restart it in download mode again and plug it back in the Flash Tool just says "Waiting for Connection" and doesn't do anything.)
At this point I am out of ideas. I have a feeling that since I cannot even power the phone on unless its connected to USB/Power Adapter something is seriously wrong, but I have no idea what Titanium could have restored to cause this.
Any ideas or suggestions would be greatly appreciated.

Did the same thing myself and nearly crapped myself. Here's how I got out of it:
Power down the phone (hold down power button)
Turn on phone by holding power & volume down buttons
When the LG screen comes up, let go of the buttons and then hold them down again
You should then get options to factory reset.
I will say this, I was never able to restore SMS or call logs from Titanium. Doing a few factory resets just made me stop caring.

Thanks for the reply, however no matter what key combo I press I cannot get the phone to power on unless it is plugged into USB/Power Adapter so I cannot get into the stock recovery app.
Any other ideas guys?

This happened to me while flashing as well.
You have to keep trying, the timing of exactly when to release the buttons and press them again is very precise, meaning you don't have much time at all.
It took me several tries to get it back to recovery.
I also only released just the power button, not both,
Good Luck!

Where you able to power your phone up by just pressing the power button (without it connected to anything)? That's what keeps throwing me off about this whole thing, without connecting it to something no matter what button(s) I press the phone simply will not do anything.

please do!

So I tried TWRP but ADB could not see the phone. As a last resort I tried the TOT restore method on the computer that I used to root it initially and it actually went through. Once 10B was restored it finally booted back up and OTA'd 11A and I was able to re-root it after that.
Lesson learned, next time I will not try to recover the phone using a difference laptop then I rooted it on.
Thanks for the help and suggestions guys!

OTA Bootloop Help

I have a Verizon LG G2 I tried to flash my backed up stock recovery with Flashify so I could flash the most recent OTA. After accepting the OTA update my phone restarted, tried to install the update, hung at a black screen but was still turned on. If I power it off and back on it shows the LG logo, some white text, then goes to the same black screen. What appears to be happening is that my backup recovery did not restore properly and it's hanging when it tries to go into recovery. It's almost like my recovery partition is blank.
I've tried to follow the instructions to flash back to stock, but I do not believe I'm actually able to get my phone into download mode. When it is plugged into my windows 7 computer with the LG drivers installed it shows up in device manager as QHSUSB_BULK.
Is there any way for me to push a stock recovery, or even a custom recovery to my phone so I can somehow salvage it, or am I permanently bricked?

Ive looked through a lot too. and its crazy how that would happen i made sure it was rebooting correctly before i took the ota and then when i did the ota bam! only screens i can get to come up are the hardware key control mode and the factory hard reset which both go to white screens after I do them both. every one else probably has not taken the ota.

One difference in what mine is doing and what your phone is doing. I go to a solid black screen not a white screen. It's very hard to tell my phone is even turned on. I'm having to look if the back-light to verify if it's on or not. I can hold my power button for 10 seconds through one LG logo cycle and then it turns off.

I hope someone helps us out. I really cant afford a new one because the warranty is void. I was going back to stock because of all of the little bugs that need to be ironed out in roms. cause kit kat is around the corner hopefully and my problem virtually is the same i might have had my brightness on auto or something prior to that.

Ignore all the message, unplug you phone get ready to type the command, plug it in and immediately press enter to run the command. it took some trial and error, and i had to use this other post to help me out. I actually got fastboot working first, then used this post to http://forum.xda-developers.com/showthread.php?t=2477595 to get download mode working, and to flash twrp recovery. After that i used this post to run the command line from with twrp. http://forum.xda-developers.com/showthread.php?t=2451696 . I didn't have to flash the factory tot to my phone, but i have that option now because download mode is working. This process will work, there is hope for you getting your phone back. I'm fully recovered. I decided 12B is not worth it in the mean time, but if you want 12B you need to flash the factory tot and then upgrade. There is a way to root 12B, but as of this time you are unable to get Custom Recovery on it.

[Q] Help, twrp install, no boot

I have LG G2 vzw VS980. I was following this thread to try and install twrp.....now my phone won't boot, it flashes the LG splash screen for 1 second then goes blank, this repeats when power button is pressed.

Not sure what happened, but i can't get into the phone in any way shape or form!!
This is the thread i was following.....I tried to push it via adb but that wasn't working, so i tried to flash it with flashify and i think that is what has me borked....
