G2 bricked won't boot past LG - G2 Q&A, Help & Troubleshooting

Hey guys I just got another one of these damn G2s
Anyway, got root fine on 12b and had issues trying to push the twrp recovery image to it, it kept failing for some reason. So I tried the Flashify option... and as you can tell by the thread title it worked excellently. And by excellently I mean I'm bricked.
I can get into download mode. But it won't boot past the LG logo. All I get is a black screen. Can someone help me revert to stock and get twrp installed?
Thanks:laugh: I'm using an S4 right now so no rush.
Also I'm a little illiterate on Android so take is slow and dumb it down- I don't develop and I don't code, I just enjoy other people's work as a casual user.

Try holding volume down + power
Immediately when LG appears let go of both and ONLY hold onto power, should boot into option to factory reset
Hit power button 3 times to continue.

Tried that. It processes the reset and then immediately tries to reboot, and bootloops again.

Also before flashing back to stock, read the directions several times so you have a understanding

WHen your g2 is powered off just hold volumeup and connect to a PC. If it doesn't go past the blue dots then you can't enter download mode either.

The white screen where you can hard reset the phone? Yes.. I can get into it, but accepting the reset simply puts the phone back into a boot cycle.

I am not getting that error. I had that problem before, but this is totally different. I get LG red screen then I get this error:
secure booting unsuccessful
Cause:
and then this keep happening. I can go in to firmware update. Nothing much. I tried to use LG g2 stock guide, but no luck either.
When I thought I bricked mine I tried using this

Its tricky but it worked for me when I couldn't get past bootloader. All you need to be able to do is get into download mode.
Just FYI don't ever take OTAs after flashing custom ROM. They never seem to turn out well.

Thank you guys.. I got in to recovery mode and install my back up. Don't know how i got in to recovery mode. I kept pressing different combination. Once again, thank you.
Bricked in a weird way
I think I bricked my phone in a similar way except I can't get into download mode or anything the only thing I can do is go into the hardware control mode and the factory reset mode when I try to factory reset it scrolls on the top right something about boot certification then it disappears and i get a black backlit screen and can do nothing

[Q] Sprint LG G2 (LS980) Stuck in Bootloop

Well it's been a while since I broke a phone, so here I am!.... again
LS980. TWRP Rooted. Failed CM. Now stuck in boot loop.
I'm running Windows 7 64bit. I have latest LG drivers. Phone can boot into recovery but nothing else. I cannot boot into LG's "Download Mode". I can get into the "Hard Recovery Mode" which doesn't work anyway (Vol Up + Power). From recovery I can select to wipe cash and data and I can select to install from sdcard (no cards on this thing) or from ADB. When selecting ADB and trying to sideload stuff to it, it tries to load but always fails. If I try to push stuff it always comes back :closed
I cannot access any form of Fastboot. All i can do is let is loop or enter recovery. Since it seems to be the only thing I can access, can someone please assist me in what I should be trying to sideload that might get me a step further? I cannot fastboot so anything there isn't an option. Seemingly all I can try to do is sideload something. What... I'm not really sure. And no :crying: I don't have a backup.
Please help!

You were right, I was doing it wrong. Once I got into download mode it went easy.
Response to others, I found that if I held vol down by itself long enough, the phone would stop bootlooping and shut off. I could then properly go into download mode.
Thanks for the help

1. Hold the power button until the device is OFF.
2. Download LG drivers to the PC (LG VZW_United_WHQL_v2.11.1) and LG mobile support tool (B2CAppSetup).
3. Install these packages.
4. Plug in you USB cable into the phone but not the computer.
5. Hold volume up and insert the USB cable to the PC- the phone should boot to 'download mode'.
6. Open the support tool and click Options>Upgrade Recovery, follow the prompts.
7. At the first prompt indentify your phone using IMEI/ESN, then click OK
8. Let it do its thing, the phone will reboot and most likely have a bunch of error messages and some FC's. Just hit okay to all messages, the phone will settle after 2 minutes or so.
9. Download freegee from market and reflash recovery of your choice.
10. Make sure you have a ROM saved to the SD to flash
11. Use freegee to reboot to recovery
12. Once in recovery you can reflash the ROM as normal.
13. Reboot and Profit!
*$* Or you could go back to Stock and start fresh!
*$* BEFORE ANY FLASH ALWAYS STOP and MAKE A NANDROID BACKUP!
Good Luck and if you get stuck let me know
Similar issue
I'm stuck in bootloop, no custom recovery or root. All data has been deleted. I have tried the LG support tool, but it locks up. It also tells me my device is a test model, something bad has happened. I can get into download mode but can't flash stock, via the flash tool. It says wrong device, and at the download screen where my phone says rooted it says the model is a D802! Somehow this info got jacked up! I can almost make it through the D802 flash but it fails also. I only did that to confirm my suspicion that the phone thinks its a different model. I'm open to anything, I've tried it all.

How? My phone only boots to download or stock recovery. What mode does the phone need to be in for the tool to work? I can get the process started but the tool locks up every time.

[Q] Stuck in Bootloop with CM11

So I'm rooted with TWRP loki and had CM 11 on and running for a while. I just downloaded the latest nightly through CM OS and it asked to be rebooted.
Upon rebooting to TWRP and installing the update it then just kept on trying to reboot with the CM logo. I cannot get the power and volume keys to boot it to recovery and my computer won't recognize it in this state to boot into recovery.
Any ideas??!! Please! I don't know of any way to restore it.

I had to take the back off and manually unplug the battery to turn it off. Then I tried the button combinations posted *power and V down* when LG logo comes on repeat to get to wipe screen. However, the phone did not go to the wipe screen, it just rebooted again.
If I could get it to boot to recovery I'd be golden.

Error due to low batter. I'll have to see if I can charge it without it wanting to turn on. However, it looks promising -- after three times trying I got the utility to recognize the device at least!
Either way, I appreciate the assistance.

got a big problem

I let my sister use my phone and she did a factory reset. Now my phone boots up to the Samsung logo with custom at the bottom says booting into recovery at the top and then shuts off and does it all over again. I even tried holding up home and power. Is there anything I can do to fix it or am I screwed? It was rooted with 4.4.2

When you put the battery back., do you press and hold down volume down and power button and then whe I the logo appears you rapidly release and press and hold the power button without removing the finger from the volume down?
Its all about timing to be honest. Took me about 10 tries before I noticed I was being stupid. Right before the corrupted screen shows up, there is a very small window that you have to do this at. What I do is this.
I hold the volume down button while it is fully powered off.
The I press the power button and as soon as I see the LG Logo (It pops up for a split second before the corrupt screen) I let go of the power button and then press it imminently after I let go of it and TWRP shows up in a few seconds.
Again, its all about timing.

To be honest, im the least qualified to try to help! It just stays at the lg logo the entire time? No static screen or anything? And TWRP crashes no matter what? If you can get it into download mode you could try to restore jt using a KDZ for your model?

you could try to push TWRP into the system by using adb, just in case it has become corrupted. Then, if that is the issue then that should fix it.

Weta is amazing, just use the one for your phone! Or it wont function. If you have the tmobile model then only use the tmobile rom xD Just make a backup in TWRP before flashing so you dont have to start completely over.
