[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.

When you plug in the device via USB and hold the vol+key you should get the same prompt for a factory reset...

When I do this the only thing that happens is a small message comes up saying "Download Mode" and then the phone immediately goes to the firmware update screen....

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!

Before flashing and getting into rooting your phone and flashing a recovery, I suggest you to read about it.

[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.

G2 bricked won't boot past LG

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.

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.

Just remove the battery, put it back again and go into recovery mode (twrp). And do a clean flash again. If it doesnt work, then just flash another rom. Put the rom inside the sd card and flash it via twrp

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.

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.
