I have Cyanogenmod 11 on my LG G2 and everything was working fine until I plugged my phone in to charge it earlier today.
Now it's stuck at a firmware update screen and no matter what I do (even trying to boot into my sideloader) doesn't work anymore.
Funny thing is, it booted normally into Cyanogenmod a few hours ago, but now the problem is back. Any help please?
You can manually reboot into recovery using volume down+power button. Holding the power button forces a reboot, so hold the combination keys after it reboots. The phone should show a white screen that asks about factory reset, ignore and follow the instructions listed then recovery will boot.

I unlocked the bootloader and flashed a custom recovery. I then rebooted the device. Now it is stuck at the bootloader (white Google logo on black background) and I can't get it to do anything else. I've rebooted it a bunch of times including with the vol + and vol - buttons held down to no avail. I've also let the battery run out and then tried to boot it up again and the same thing happens. adb nor fastboot see the device and it doesn't show up in the logs on my machine (Mint 13) as coming online at any time.
Most of the times I reboot it with the power switch it reboots to the Google logo even without me letting go of the power button. Sometimes I can get it to fully power off but I haven't figured out what combination of vol keys and reboot does that.
Anyone have any ideas what could be wrong? Any help would be much appreciated!
You are not bricked if you can still get into the bootloader.
Download the factory image from here, and flash it with fastboot. If you don't know how to do that, read this thread.
I wish I could get fastboot to see it then I could definitively flash that img.
I can't get into the bootloader and can't get fastboot or adb to see it. It's stuck at the Google logo now and when i hold the power key it reboots back to the Google logo with the unlock logo at the bottom.
Thanks for the help
You've tried holding volume down+power for 10+ seconds? That should power off the device, then hold both vol up+down down and power up
Ya I've tried to hold vol + and power for 10+ seconds and it reboots back to the Google logo even if I don't off the power key. Same happens with all the other combinations of keys being held with the power button. I can't get it to turn off now unless I let the battery die
Press and hold power till screen goes black. Then quickly press power+volume down and HOLD.

Tried that and still stuck at the Google logo. I have to go to work for a couple hours and then will hack on it when I'm back. Hope I don't have to deal with Googles rma process seeing how disorganized the rest of that company is

No luck with any button combos but the vol + and power actually turned it off. All out of ideas over here. I'm thinking it really is bricked
I'm in the same spot. I can get it into recovery occasionally but once there it locks up after trying to flash or clear the cache.
I'm wondering if a contributing issue is CMR v6.0.0.6? I updated it from 6.0.0.4 that was running fine. But no fastboot or adb so that is doubtful.
This is frustrating and not a great start with this N7.
thank you

this worked. you have to be fast. as soon as screen goes black release power button then quickly, very quickly repress along with vol up and down.
You will still be able to get into the bootloader! Force kill the tablet by holding the power button for ages. Then hold volume up and volume down and the power button together, which will boot to fastboot.
It looks like a CWM bug as I feared. Anyone in the same boat try here - http://forum.xda-developers.com/showthread.php?t=1782932
Nothing has worked and I've literally tried everything that those three buttons can do. Thanks again for all the help guys. Had a great time trying to resurrect it but guess it's time for it to go back home
Just as I suspected. Google puts out buggy junk once again.
I just wanted to report a similarly event. I have a rooted, unlocked Nexus 7, with TWRP recovery. I have previously rebooted without issue. Tonight I booted into bootloader mode to check something and the hit power button to choose start. I got stuck on the boot logo. After finding this thread, I started with the simplest combination and held power button until screen went dark, then added volume down and once again in bootloader. This time choosing start led to a regular system boot. It's as if the device froze and needed a hard reboot.

I was attempting to boot into recovery and kept getting the 'Google' logo (I am unlocked/rooted with twrp recovery). I wasn't aware that one had to be plugged in via usb in order to *not* hang....
Any way around this?
Once I plugged it in and attempted to boot into recovery it worked fine.
I had a similar issue after using the Nexus Root Toolkit to flash to nakasi 4.2 with CWM recovery - just got stuck on the nexus boot screen, flashing in a loop for over 15 minutes.
I ended up powering down the device, holding power for about 5-10 seconds - then QUICKLY holding both the power and volume up+down keys, it then went into the fastboot screen.
After it was there, plugged it into my PC.
Now, this should work for you - assuming you have all the fastboot/usb driver stuff installed.
I extracted the contents of nakasi-jop40c-factory-6aabb391.tgz into the same directory as the fastboot.exe provided by WugFresh with his Nexus Root Toolkit (google search or xda search for this if you dont have it, i dont think i can post links due to my low postcount) - typical filepath: C:\Program Files (x86)\WugFresh Development\data
By the files in there, I mean drilling down inside the tgz to where the image files were inside so that files like bootloader-grouper-4.13.img, image-nakasi-jop40c.zip etc were extracted into the directory and sitting alongside the fastboot.exe - NOT in a subfolder.
Once its all here, running flash-all.bat (this is provided by google in the nakasi-jop40c-factory-6aabb391.tgz) from the command line or by double clicking on it from explorer should kick off the process. After about 2-3 minutes, it was complete, and my Nexus then booted up within about 3 minutes after that.
Also worth noting, device remained unlocked, but I lost root/root binary
Stuck in a boot loop after attempting to restore my T-Mobile 801.
It boots up to the T-Mobile splash screen does its little ding a ling thing then 10 seconds later restarts the loop.
I used this http://forum.xda-developers.com/showthread.php?t=2432476
Any other ideas?
Looks like I got it, I did a factory reset on top of it and seems to be working again.
Can you tell me exactly what you did? I seem to be having a similar problem with the Verizon G2 and can't get anything working.

After I ran the factory flashing tool, the phone would boot loop (I think most likely because the settings and profile from the last rom wasn't reset by the tool.)
So what I did was use the factory recovery option in the phone by doing the following.
1. Power down the phone (Hold power for 15 Seconds)
2. Press and Hold Vol Down and Power
3. Quickly after seeing the LG logo release the power (while holding Vol Down still) then pressing and holding the power again. You should get a white screen asking if you want to reset your phone press Power to Confirm twice.
A little android pops up and does some work then reboots your phone. The phone should boot after that.
Hi so I have a T-Mobile LG G2 (D801) which has stock KitKat rom and rooted with custom TWRP recovery, I also installed autorec to fix download mode. I was trying to revert back to Jellybean 4.2 and I bricked my device. I followed this thread
http://forum.xda-developers.com/showthread.php?t=2432476
and used the kdz method. I held volume up button, plugged in the device, got download mode, tried flashing the file and got some kind of error, it was in korean so I couldn't read it. As it was flashing it went up to 6% on the device but thats when the Flashtool gave me an error. I tried to exit download mode by holding down the power button till the LG logo appeared. I did that and when it appeared I unplugged the device. However now the device won't shut off and is stuck at the LG logo screen. So I dissasembled the phone and unplugged the battery cable from the motherboard and it shut off. I then plugged it back in and tried to enter download mode, but nothing happens, it's stuck at the LG logo. If I hold it for 10 sec the screen turns black and LG logo appears again. I also tried holding it down and when screen turns black I hold down power+vol down (to get into recovery), screen turned on with LG logo and I removed both buttons and then held power button for 2 sec and that worked. And I tried to do a factory reset, but it basically freezes at that screen. It is stuck on “factory reset processing” for 20min now. Also I'd like to clarify that this is the stock recovery not the TWRP that I had installed. I tried double the power buttons 3 times in stock recovery to enter TWRP but nothing happens, it just says "factory reset processing".
I'm not sure what I should do now, is there a way that I can flash something via adb and load a custom recovery or rom? Or go back to stock rom?
Please help.

What is your phone doing exactly? Bootlooping in TWRP or something else?

I'm also in the softbricked state of routing the Sprint V20 in the dirtysanta way. The phone system will not boot, and it will continue to twrp. I installed the LS997 rom and superSU on twrp but it is not installed and only twrp will boot. Have you found a solution?
I battled this for hours and hours yesterday.
Pull the battery for a few seconds then replace it.
Hold volume down and power button at the same time. As soon as you see the LG logo - release and repress the buttons. Continue holding them until the factory reset screen comes up.
Push volume down to move to yes - then push power button to select.
Repeat above line a second time. Don't worry. If you have TWRP recovery installed it will not reset.
If you don't get the button push right and end up back in TWRP recovery without seeing the factory reset screens - just pull battery and try again.
Once you go through the 2 factory reset screens - it will bring you back to twrp recovery one last time but will remove the looping into recovery.
In TWRP Select reboot - system and it should load normally now.
It will take a while and you will be stuck on static screen. Try tapping the power button just to turn screen off. If screen turns off - lay phone face down to block light from entering sensor by front facing camera for a few seconds then tap power button to turn screen back on.
If after 15 to 20 minutes it doesn't load. Pull battery and replace. Push power button and it should load this time assuming you wiped and flashed a rom properly.
I just rooted and flashed using this method and all appears to be well. @midmadn are you saying I can expect to be in the static screen for up to 20min?
Possibly on first boot. I usually give it 10 to 15 then pull the battery. It has always booted after the battery pull and in a short amount of time. Maybe a few minutes.
Usually you can hear the boot sound or when screen turns off then cover sensor and press power all good.... You may hear the woman talking also after boot to set up handicap or something

I recently updated my Samsung Galaxy Tab A T280 to the latest firmware and I lost my root. So this afternoon I re-rooted it. Or I attempted to, anyway. Everything seemingly went fine, and I booted into TWRP just fine. I went to flash the ROM and I also selected wipe cache/davlik cache to be done as well, and tapped reboot. My device then turned off and when it started the reboot, it got stuck on the Samsung Galaxy Tab A logo screen and would not move or power off by holding the power button (I tried for a LONG time by using a rubber band to hold it down so I didn't have to, with no luck), and every other combination of buttons wouldn't do a thing, except for holding power + vol down, which made it turn off and back on, but it wouldn't finish rebooting and it just got stuck at the Samsung Galaxy Tab A logo again. So then I thought that maybe plugging it into a charger might not be a bad idea, and after holding down power + vol down again, it turned off and turned on and showed a battery with a charging symbol. I've had it plugged in for an hour and it does not show a charge or do anything except for go back to that boot logo if I unplug it from the charger and again hold down power and volume down separately.
I know it's not hard bricked because it is somewhat responsive so I think there's a chance to fix it, hopefully. I just want it to turn on and fully reboot into anything or in any way that will allow me to be able to fix the issue. My computer will not recognize the device so ADB is not an option right now unless I'm wrong.
Thanks a lot guys, I am so confused and could really use some advice.
What firmware did you install
Try to install original firmware via software "Samsung Smart Switch" on your PC with connected tablet.
I too recommend that you try installing the last firmware that you were on via Odin. Also, when you hit that screen lock issue after a firmware flash, where only the Samsung logo appears do this:
1. press and hold Home + volume up and volume down along with power button (that's all 4 buttons). Hold it there for at least 20 seconds and it should power off.
2. Once the device powers off keep holding the buttons but let go of the volume down button.
3. Once the tablet starts to power back up again release the power button and then in about 1 to 2 second release the rest of the buttons.
This should get you back into recovery. You should at least be able to restore any backup, that you should have already, on your external micro SD.
Good luck.. : )
"Chance Favors the Prepared"
the above post is 100% right. Reboot back into recovery and you'll be good to go. Also twrp has a option to reboot back to recovery so this doesn't happen, just a fyi for future knowledge. Best of luck..
You tried to flash a rom with twrp?
You need to flash stock firmware with odin.
