I need immediate help please! my phone is the only communication i have. I rooted the phone a while back with superuser and titanium backup, recently i downloaded twrp and wasnt sure how to use it. I believe i flashed it with twrp and then today i tried to download the new update via ota from verizon. I am not savvy with computers or cell phone rooting. I need someone to walk me through unlocking or unbricking it. It will turn on and show the lg screen and immediately say "boot certification verify" and the screen will go black. Ive searched for hours and cannot find a fix to get my phone back to normal. Please help, im on windows operating system if that helps also. Ive seen some posts here but nothings worked. Thank you for any help

The only thing you need to do to get into Download Mode is turn the phone off, wait about 30 seconds, and then hold Vol Up only while plugging the phone into the PC. A few LG devices don't have access to Download Mode, but your variant is not one of them. If it did mess up so bad you only have access to TWRP, then you can try this:

And then try to get to Download again or there might even be an option from the TWRP Reboot menu, if I remember right.
verizon lgg2
it wont get to dowload mode or twrp just says boot verify certification pn the lg logo screen

I was having trouble getting android to boot and I was getting a message that said that the phone needed a restore. I downloaded the emergency recovery build for VRUEMJ7, the build I was on and flashed it with 3.09. I got a good flash notification in Odin but when it reset everything is black, phone doesn't come on at all (at least the screen). I tried a different battery and when you plug it into a computer it gets a USB device connected sound. Did I kill the phone? Any way to get it back into ODIN download mode so I can try the flash again or get it to come on?
What could I possibly try? Thanks for any suggestions.

No matter what I hold down on the phone it doesn't seem like the screen ever comes on. You can tell it's doing something because when you plug it into the computer it makes a USB device connected sound. It hasn't been damaged or anything like that either, so it has something to do with what happened when it was flashed, however it said it was successfully flashed on the phone and ODIN before it restarted...
99% u hard bricked it... Did the same thing on my own S4 - http://forum.xda-developers.com/showthread.php?t=2539877
I Tried everything posible... but the phone was dead! No download mode no recovery mod...
At the end JTAG solved my problem, cost me about 35$ here in europe...

Currently bought a sch-i905 4g lte verizon galaxy tablet.
Boots normally, and functions.
Last night i was writing a bootloader through odin, and accidently had auto reboot checked. I was unable to write the modem/kernel that goes with it and now have a galaxy tablet that boots into the OS just fine.
The problem now is though that i can not get my tablet/computer to communicate in download mode it says "waiting for cable"
as well as my recovery is a black screen of doom.
Through rom manager when boot the tablet up i can see that clock work is installed just not boot properly..
I need some help here guys since this is outside my knowledge of fixing.
i can boot into the android OS, but when i charge it while its on it wont actually charge, the X is over the battery, but if i leave it off i can charge it just fine.

unfortunately when i use download mode, it only shows "waiting for cable" no matter what pc, what driver, and what cable i use.
If i boot into normal android, the drivers load fine, i can transfer files etc . just cant recognize it in download mode.
so without recognition from download mode,
a blanked/blacked out recovery mode
im not sure how to fix it.

its under my impression that hard reset will not fix download mode or recovery mode.
well, i did a factory reset, and now my tablet just goes to the samsung tablet 10.1 and still boots up with an ALL BLACK screen.
once its completely turned on, I can hit the power button to dim it, then i hit the power button and all is well im back to android os.
now you've fixed my battery charging issue while my tablet is on, so i am forever grateful.
Next 2 things to fix:
Download Mode & Recovery

Have you tried using odin?

Hey guys i got a slight problem.
I had the Android Revolution HD Rom and i was trying to install another one , it really wasnt my first time doing this however this time a problem occurred.
My volume side buttons are not working so i couldnt get into recovery mode using them also on top of that the rom itself didnt have the option to go to recovery when turning off the phone.
I downloaded the Quick boot tool apk from Playstore and used it to go to recovery... I WISH I DIDNT
now my phone when turned on shows samsung logo and it goes to recovery and quickly goes back to the logo and loops in that way...
Is there anyway to access the download mode without pressing them sidebuttons, i even tried ODIN but it cant recognize the phone because it keeps looping...
I am clueless now and any help would be appreciated.
Sorry for spelling or any typos i am really angry atm.

You can use Android Debug Bridge (ADB) to enter whether download mode or recovery.

It doesn’t sound good then. Please read again threads like this on how to recover from a bootloop. If you really can’t access neither recovery or download mode using adb, that’s out of my knowledge, and you might need to read about how to fix a hard brick. There’s a thread about that in these stickies.

i managed to get into download mode however prior the brick i didnt enable developer mode on the phone and now the pc cannot recognize it when connected.
Developer switch is irrelevant to download mode, search the many threads on things to try to get Odin connected.
I tried to flash a rom using Odin but it failed. The phone now stuck at LOGO screen.
I entered download mode and noticed that the REACTIVATION LOCK is ON. I think it prevents Odin from flashing anything to the phone.
I tried to enter recovery mode, factory reset but still same. In recovery mode, there is a line saying "failed to mount /system".
I don't know what to do now. Please help.

Yes I tried to flash back to stock firmware but failed. I searched for solutions and it seems its because the reactivation lock is blocking odin from flashing anything to the phone.
Hello, did you try Smart Switch? I had a similar problem after rooting then stupidly activated Knox, but Reactivation Lock was OFF as once you root it seems like you can't enable it, my answer was Smart Switch which initialized everything

Hi. Yes I tried smart switch, it says it can not reognise the device. After I failed to flash the ron for tge first time I was able to boot the phone, knox ask me to restart the phone so I did restart it. I think it was when reactivation lock was triggered. after that the phone is not able to be booted. No idea how to disable the lock.

Do you have the latest odin? Read somewhere someone with the same issue and the problem was odin. He installed the newest one and everything was fine.
Good luck
I am in same situation. Yesterday I was able to reinstall original firmware. Trick is to get Odin to recognize com port. By connecting to USB first and then entering download mode it seems to work.

Hold it down for like 20 seconds and keep repeating it. It will eventually boot into download mode.
Once in download mode just flash stock and it will work. Try it if you get any errors get back to me and ill help
