[Q] Royally Screw... Stuck in Fastbook (VZW model) Please Help!

First off, I searched for someone with a similar problem and couldn't find anyone in the same situation.... Also, I'm very familiar with the root/flashy/etc. process coming from a GNex
So I rooted the G2, no problem at all (before OTA). Trouble came when I tried to flash recovery. I couldn't get it to do so, but I was following a guide that stated I needed to perform the OTA before flashing TWRP.
So I finally accepted the OTA and when I did, see first pic, it clearly asked if I wanted to perform a factory reset, I accepted. Then I get dumped into Fastboot, see second pic, and I cannot get out of Fastboot at all. In addition to that, when I plug it up via USB, it won't recognize the phone at all either.
Verizon of course said I was good to take the phone back and have it replaced, but thanks to the "tell tell" message on the Factory Reset option, check first pic - top left corner, they can clearly see it's rooted and will likely not replace it, and I'm out a ton of money.....
Are there any ideas out there as to how I can recover anything????
Thanks in advance!

You not the only one! I think the recovery partition may have got corrupted from a bad CWM flash file. I get the same black screen, fast boot bull****... phone still works at least lol.
You can always flash back to stock with the lg mobile suite, got me out of a bootloop. It should fix recovery partition I would hope

Where do I go to get that?
Or is there anyway I can actually make the phone connect to my computer via USB so that I can hopefully use the Verizon Upgrade Assistant?

I used the LG mobile support tool found here: http://forum.xda-developers.com/showthread.php?t=2432476
follow the steps, after the top right of that program will have drop down with "recovery update" or something to do a full restore.
I hope you can get into download mode for this, power +volume up
Good Luck!

Thanks for the thought, however that thread is assuming you have ADB access which I cannot get my computer to recognize my phone while it's in fastboot through ADB....
Downer I have a day old phone and I may have to go ahead and make an insurance claim against because I'm not paying $549 for a new one...
Or is there a way I can completely bork this so it doesn't even get to the Factory Reset option, or at least so it won't show Rooted, so I can just take it back to VZW haha???

Hold the volume up and while holding, plug in USB. Should put it in download mode. If adb then can recognize, reinstall the recovery. If not, hold the power and volume down until it starts to reboot, when you see the LG logo, let go and immediately repress them and hold until it asks you to push the power button to reset phone. When you do reset, it will actually take you to the twrp recovery.

So if u can get into download mode use the lg moble softwear to restore it.adb is not required for that

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?

I'm still trying to find a solution I will post here if i have any luck. I've dug through a lot of forum posts and I think what makes us unique is the fact that we have a corrupt or blank recovery partition.

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.

Thanks for the link. I'm tryingto follow the instructions,but when I get to the step where i plug in my phone it just showes up as a bunch of failes partitions, and slows my ubuntu to a crawl. I'm a linux noob, is there a command i can run to stop this from happening? I also created a reply asking this question in the link you sent me.

After following the instructions on the above link i was able to get fastboot status on my phone. It did not fully restore my phone however. I was able to flash twrp via fastboot. I was then able to boot into twrp and run the command at this link via twrp terminal http://forum.xda-developers.com/showthread.php?t=2451696

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.

lg mobile support tool stuck at 49%

i tried going back to stock firmware using the method in general section but i always seem to get an error at 49%. can someone explain how to get passed this.

HEY! I'm on the d801 as well and I've been where you're at a number of times, unfortunately. But I've always gotten out. Here's the conclusion I've reached. Trying to flash directly back to stock without wiping all the partitions first is what makes the RDTool get stuck. It's like the phone runs out of memory and can't host a full Gig+ of data since your last ROM is in the way. Sorry if I'm wrong but I'm only assuming you didn't wipe everything except the Internal storage. The good thing every time this has happened to me is that your recovery partition should be intact. Mine always is, and we're on the same variant. Another thing, booting back into recovery is not impossible. It's all in the timing it takes from the first time you see the LG logo while holding volume - and the power button, but don't let go. What worked for me was to let the phone cycle between off and boot power states twice until the phone is completely off again. You may even notice the LED indicator flash red. Release your keys if the phone stays off and immediately hold the combo down again until the phone tries to boot again just don't let go of the buttons. Once it powers down again, leave the phone alone for a few minutes. Come back and this time get ready to boot into recovery. The combo button press will initiate boot but don't let go until the next time you see the LG logo flash, then quickly release and depress the vol down power up combo and hold. May take a minute longer than usual but the reset menu should pop up thereafter. Tap power 2 more times and you should back into recovery. It's worked every time for me. Let me know if you're good and whether this helped!
Good Luck,

OK. So tell me, what ROM were you on, which recovery version and name are you using, why were you flashing back to stock, i.e. were you having problems, what kind. Explain as much as you can in detail. Need to retrace your exact steps to best get you fixed up!

K, now if you're only seeing the blue dots when you attach by USB your phone to PC, then you're not fully in DL mode to process the kdz. You should see a white wheel in the center of the screen when you connect and a viewing mirror near the base of your phone with ROOTED in red directly below that. And you're sure your PC is detecting your phone? You've the drivers installed? Because when RDT tells you to run the tool, you'll see some binary code in the viewing window I spoke of, the white wheel will turn and below it will be shown the COM port to which you're connected and a solid thin red bar will begin to fill a space in the viewer showing you the progress.
Also, be sure when attempting the first steps I gave you to boot into recovery that you are not USB connected. It won't work.
And, try to remember if your phone was well enough charged, should have been at least 80% full. It happened to me once that I couldn't boot recovery and my phone would go to fastboot like yours until I left it alone to charge and then I repeated the stepsvi laid out to get back into recovery. This part is paramount!

Please READ CAREFULLY
I used to be in your same situation. I thought I had bricked my phone for good. I finally figured it out. Here is my solution from my Thread.
Esteef said:
Okay, after 12+ hours of trying every method possible on XDA I finally resolved my issue. I will update the first post just incase any others care or fall into the same dilemma I was in.
The LG Mobile Support tool would not download the firmware and it would NOT ask me for my IMEI to download it either.
So my solution....
***
Installed LG Mobile Support Tool then Installed the LG Drivers. (FROM HERE http://forum.xda-developers.com/showthread.php?t=2471370
BEFORE I connected the phone to the computer. I opened the LG Mobile support tool clicked (Options on the top right).
When the dropped down opened, I clicked the (Upgrade Recovery) option. THEN, is when the prompt opened to ask me what my IMEI is.
Before I entered my IMEI, I connected my phone to the computer in download mode, then proceeded to enter my IMEI and hit OK.
This is when the LG Mobile Support tool SUCCESSFULLY downloaded the latest official LG firmware and installed it.
*** BE AWARE, with the phone connected to the PC, the prompt NEVER appeared to enter my IMEI.
*** But with the phone disconnected, the prompt came up every time. This might be the trick for some people.
*** with the IMEI prompt opened, I then connected the phone , entered the IMEI, then hit OK. BOOM HERPES....
Well I'll polish this up more later. I hope this works for every LG G2 Variant and not just the T-Mobile one (D801)

MY LG G2 for verizon is bricked HELLLPPPPP PLEASE

sorry to bother you all. i bricked my device and it's only a few hours old. I rooted it using the io root method. that was painless.
anyway, it didn't brick then. i got a notification from verizon for the 4.4.2 update so I clicked download update it never installed and that's when the bricking started. Anytime I connect it to the computer it opens up like 40 disks and it says cannot be used unless it's formatted so I have to spend a while canceling those out. when I restart the phone it says the lg logo then the screen goes black . im stuck. i've been trying for hours. if i get the phone back i won't root it or do anything. ill deal with the bloatware, whatever. i've tried a lot of different things but to no avail. any help is appreciated. thank you for your time...and wont go into download mode....help please anyone....
i have no recovery installed....every time i try to cut the phone off it vibrates screen goes off and on showing the lg logo very quickly then goes black but remains on until battery drains

Im in the same boat

If you can't boot into stock recovery (vol down + power key) and can't get into download mode (this is where they detect root once FW update shows up and the bottom left corner says Bootloader: ROOTED) then you can rest assure as long as you are under warranty, send it in to LG directly.
Do not send it to Verizon as you may incur charges for replacement. There's insurance from Verizon, but the real "replace with no charge" warranty is sending it to LG directly. Make an account on their website, register your G2, and make a Repair request by online chat or phone.
I just got my T-mobile G2 back after 2 weeks with the same issues and while it took a while to get repaired, I didn't pay a penny and it works without T-Mobile ever knowing its different hardware (all they replace is the flash memory that is corrupted in the phone).
Only downside is that it came back with KitKat and unrooted which means I have to wait for a working root procedure for it unlike with JB (I'm not afraid to root it again since I know what messed it up before was custom recovery TWRP version 2.6.3.2 that doesn't support KitKat lol).

I just got my T-mobile G2 back after 2 weeks with the same issues and while it took a while to get repaired, I didn't pay a penny and it works without T-Mobile ever knowing its different hardware (all they replace is the flash memory that is corrupted in the phone).
Only downside is that it came back with KitKat and unrooted which means I have to wait for a working root procedure for it unlike with JB (I'm not afraid to root it again since I know what messed it up before was custom recovery TWRP version 2.6.3.2 that doesn't support KitKat lol).
He can't get into download mode which means no KDZ flashing.

Not getting into download mode is odd especially for just accepting a OTA update. Remember since they accepted the OTA its gonna take a special way of getting into download mode as the phone will be constantly on in boot loop. not all of the time but most of the time when people say they cant get into bootloader they have to keep trying due to the phone has to be "Turned off" OR rebooted at the same time of holding down the key combo.

To get the phone to turn off, one has to reboot the phone (power key for 10 seconds) while holding volume up WITHOUT having the USB cable plugged in.
Recovery mode is a bit trickier by having to hold the power key for 10 seconds, then just as the phone reboots, hold PWR + VOL DWN and while holding VOL DWN, release PWR and press it again (gets to that factory reset screen where you press PWR 3 times).
Not trying to teach you this if you already know how, just stating it if the OP looks at this then he can try again with the above.
Also, Download mode is essentially the "bootloader" and it is locked meaning unless you have certified software (KDZ FW updater), you can't adb anything just in download mode unlike some LG phones that have emergency mode which is unlocked bootloader.

Yea I know the commands, The guide for going back to stock was created by me for the G2 haha, Hopefully the OP will see your post and try that

ive tried
ive tried factory reset "vol down & power"...its just goes black and stays the same

I'm having about the exact same problem. I rooted my phone a while back, I left it stock and just used some modules (xposed). When I noticed the update I of course was stupid enough to hit the update... My phone is doing the same as his. I can get to the factory reset screen but even if I go through there I get the same black screen (though backlit). I can't boot into download. I'm downloading the .tot needed for stock, but I'm not sure if that'll be a lot of good without download mode. I have everything on my phone backed up from when I rooted it (I'm missing a few pictures but nothing major.) Any and all help would be appreciated. I've got a bunch of precalc homework and Prom in a couple days so I'm willing to sacrifice sleep tonight. Thanks! (Made this account just for this, though I've used the site a bit before.)

It's cuz you're not doing it correctly.
Yes, you're supposed to depress "vol down & power" but once you see LG logo, let go of both buttons and then immediately hold down only the "power" button.
After a few secs, a white factory reset screen will appear. Ignore the warning and press power button. I know, its kinda scary at first, but then phone will load into recovery.

I can get to the factory data reset screen but when i choose yes it just gives me the secure boot error. I am able to put my phone into download mode by pressing up volume and power when plugging to pc, but cant get pc to recognize it. I am sure I am missing something.

i am also bricked. i cant get into download mode or recovery. i have twrp installed, cant get to that either. i have tried every button combination and all i get is a black screen and vibrations, no lg logo. need help.

Did just like you with OTA today and now bricked. Guess I will have to call Verizon and see what they can do.

Call LG verizon will void your warranty

Has anyone made any progress or did all just send back to LG?
I am in similar shape, can get to the white factory reset screen - which does nothing once I accept.
I can also get into download mode, but the phone isn't recognized.
Wanted to confirm before I try to send it back that I can't fix myself.
Thanks!

Also, did anyone who was able to get back to the hard reset screen have luck sending to LG? Or did it have to be completely bricked?

Im also bricked. And there is no recovery mode. download mode is usable. but when i in twrp before brick i deleted efs because i have a back up after that recovery had corrupted and driver in the rom memory to talk to pc had also deleted with efs(i think). I have an idea to fix but im not sure
If I can change rom from mainboard and replace it other rom from other lg g2? Will it solve my and our problem??????
thanks to reply.

no OS, no TWRP, no fastboot..... no chance?

when reinstalling a ROM earlier today, I got an error 7 ... no problem. probably TWRP problems... so, i go to reboot phone to recovery to begin fresh, and now, TWRP boots, but the screen flashes blank every couple seconds, for a second, then the TWRP splash screen comes back up. blank screen, then TWRP splash screen again. never gets further than that. because I dont have an OS installed, i cannot access debugging for adb. because i deleted my OS, i cannot allow fastboot, to flash a new recovery and begin again. ..
I am broke, and cannot afford to pay for a new replacement thru insurance or to just go buy a junker phone and make do with that.
am i ****ed, or is this recoverable...? ive been searching the forums, but cannot seem to find the answer, and im starting to get nervous enough that its sorta beginning to compound my problems more than i can deal with.
edited to add again: .... battery removed + volume dn then insert battery will not enter fastboot. im about to paperweight this ****.
again edited - Sprint LS997 is phone model. no TOT'ing for me.

What about if you remove the battery, put it back in, hold volume down and then plug the usb cable?

tried this. still a no-go. phone screen does not power on when trying this or any other combo of steps. LAF works, which is vol+ and plug in USB cable. odd that vol- and plug in USB cable does nothing. maybe faulty vol+ button? never had a problem with that button functioning before now. i have access to: LAF (download mode), and TWRP. However, TWRP 'flashes' off n on... i see the splash screen for a second, then screen goes blank, but still powered on. then splash screen again. rinse, and repeat. no response to touch or vol/pwr buttons. tried pulling battery upon TWRP splash hoping this clears cache, but still just same story afterwards.
would having access to fastboot even matter, since I have no OS install with which to give fastboot/adb access anyway?

From fastboot you can reflash TWRP which from where you can reflash the OS which would unbrick the phone.

If you have access to download mode, can't you reflash your phone using the LGUP with the backup that did in the first place?(you did a backup of the original OS right?)

Sounds like empty or bad battery to me. When did your phone start acting up upon ya? Right after root or you had it working with root etc before u ended up into such situation.
Also, as XblackdemonX pointed out, you can still use LGUP to stock.

I'm pretty sure that happened to me. And I fixed my H990DS by flashing kdz file in download mode with LG BRIDGE.
There's a guide about how to unbrick any v20 around here.

@elijah420 What software version were you on before this started? Why does it matter? If you were on ZV7 or earlier, then you can flash a VS995 KDZ in download mode, root it, and then fix your phone. If you were on ZV8 or later, then you still might be able to salvage your phone, but you will have to run firmware from another model since you will not be able to root and flash back to Sprint firmware if you were ARB 1 or later. Better than having a totally busted phone though.
Last possibility is to use the debug firehose that I have, but that is an even bigger unknown than running firmware from another model.
