[Q] Black screen after autorec - G2 Q&A, Help & Troubleshooting

I everyone, i just aquired this awesome phone.
I rooted it with towel root and everything goes fine.
Then i installed autorec and chose to reboot in recovery.
All goes well and then in twrp i chose to reboot system.
Now after the LG logo i have a black screen with the notification led activated.
i can't go back to recovery neither

Looks like ur in a boot loop. If you cant go to recovery, I suggest you go to download mode and restore to stock rom via the KDZ method.

Can only vouch this post. Absolutely solid advice.
Keep pressing the power button till it powers completely off, then press the volume up and plug the phone into the computer. Then follow get back to stock guide.

[Q] Stuck in Bootloop, tried everything.

So I just picked up this phone today from Verizon. Rooted successfully and tried installing TWRP via Flashify. Now I'm stuck in TWRP and can't even get Download Mode to come up. I've tried wiping, using the scripts in both ADB and TWRP, and LG Factory reset. Please, if anyone has any other ideas. I would be grateful!
I'm guessing you clicked "install boot img" instead of "install recovery img" in flashify, correct?
Hold the power button down until your phone is off. I mean, you're going to be holding for 15-20s. The LG logo will flash on, then go back off pretty quickly. After that your phone is off. Then, you should be able to get into download mode by holding the vol. up arrow while plugging a USB cable into the phone. Follow the "return to stock" guide of your choice and don't click install boot img next time you try to install TWRP.
I think you're right. I'm finally going to give it a shot now. I was on the road but thanks a million. I will report back on results.

There is a thread about how to get back to stock. Just try it. The easiest way is to recover stock firmware via LG Suite.

Help! LG G2 Stuck on fastboot

Okay, this is the entire story.
I rooted my LG G2 and planned to flash a cyanogenmod 11 on it. I managed to adb my zip file to my phone. However, when I tried to boot my phone into fastboot mode, and install the zip, it just stuck there. saying something like fastboot udc()... I can still power on the device and get back to the stock rom but that is obviously not what I want. So how can I get to recovery? And by the way, I managed to factory reset the phone earlier, (before it stuck in fastboot, but it just cleared the data and restarted). Does factory reset delete my cm files? Thanks
Why not just go back to stock and start over from there? Put your recovery and ROM on the phone while stock is running and then use a program like Flashify to flash TWRP or CWM. You know how to do the rest from there I'd imagine.

I have tried that... the ADB stopped working and no matter what recovery software i used, it always stuck on the fastboot...
So then you can't get back to the stock ROM? You said in your original post that you could. And if you can do that, you should be able to do the rest without using ADB at all.
Once it's stock and running, put it into MTP mode while plugged into your computer, copy the recovery, ROM, Gapps, etc onto your SD Card partition, then download Flashify from the Play Store and use it to flash your recovery of choice.
Once your recovery is flashed, you should be able to boot it into it when Flashify asks you to reboot. If that doesn't work, you can download Quick Boot from the Play Store to boot into recovery on your stock ROM.

OK. I think there are some misunderstandings. I tried to factory reset the phone from the settings. the phone went to fastboot and stuck there. I pressed the power button and it launched the LG Optimus UI. but that doesnt solve the problem. I still can't go to recovery mood. it would just stuck there forever until i press and hold the power button again. I know, it is kind of weird

Can't boot into twrp, help!

Hello! I rooted via ioroot, and installed twrp today with the app called "freegee". But when I try to boot into the twrp recovery the lg logo just go through 2 times before the phone starts and boot up (the phone is working fine), but I can't access twrp! Can I just try to flash twrp in flashify and try that?
Btw I do have root, I have checked it
Any help is appreciated!

I tried all the hardware combinations suggested on the forum, but was unable to boot into TWRP (using CM11's advance reboot to get into recovery does work).
After LOTS of experimentation, I was able to get into TWRP using the hardware buttons by doing this:
Power Off entirely
Boot by pressing Power + Vol-Down
... wait for LG logo to come up, but dont let go of the buttons [this is where my attempt differed from the other instructions that suggested letting go of Power + Vol-Down and pressing it again]
LG logo will very quickly go away and the screen will be off again
THEN start it up by pressing Power + Vol-Up [normally Vol-Up is for download mode]
It will show the factory reset screen ... press the power button 3 times, and it will go into recovery
I don't know why the above method worked for me, or if this will work for you (or anyone else), but this is the only way I was able to get into recovery. In case it's relevant, I have an LS980 (Sprint).

how are you trying to boot into recovery? I myself can't get the button combination to work and use titanium backup or freegee to boot into recovery

Thanks! It worked now, I just couldn't find out how the button combination was then,..thanks to both of you :good:
One last question, when I take a nandroid, do I just backup my system, boot, and recovery to backup a working rom, or do I need to backup data too? Because my data is on 3,2 gb and I don't have space for that lol

You can also download TWRP manager and use the reboot option to boot into recovery. Don't have to try and time the hardware buttons.

Need help desperately :(

My phone won't boot after installing the latest DU custom rom. I followed the steps here https://plus.google.com/+AlexCruz/posts/JJ5d9v6DArW - rooted and installed latest clockwork mod recovery, did a backup, and wiped everything, then installed the custom rom. But now it is stucked at the Dirty Unicorns boot screen.. Please help.
Some extra info: I was on 4.2.2 (802 international) before the flash
Edit: i can't even get to recovery now, by holding power and volume down buttons at LG logo. Is my phone dead?

Are you getting to the factory hard reset prompt? You have to go through that to get back into the recovery. Then you can just restore from Backup.

--This is copied and paste from another thread--
"You should be able to get to CWM recovery by using the hardware button (power and volume down held down, flash LG logo for a second, and then shuts off--only then you can turn it back on by holding power and volume down together until LG logo pops on, then let go of both buttons quickly, hold down both power and volume down again, and then quickly let go of the volume down button: a white factory reset screen should pop up and then you can push power button alone twice to enter CWM recovery).
If above does not work, you may need to KDZ back to stock using download mode (google LG G2 download mode) and USB cable (the one that comes with the phone as some USB cable won't work as they're charge only cable). You'll have to reroot with IOROOT25 and start over again."
--
I have no idea what fastboot or download mode is but your phone should be soft-bricked? If you can get into recovery or the factory reset screen you should be safe.
I wasn't able to get into the recovery at first but then I kept trying and trying and managed to get in by luck. Lol. I then wiped everything including Dalvik cache in Advanced and rebooted and was relieved to find it booted into Dirty Unicorns. I guess i was lucky.
