I would try booting into recovery to restore a nandroid backup or re flash your rom of choice. To get to recovery, try holding down your power button for a number of seconds, and continue holding until it goes to reboot. Then hold volume up until you see the blue lettering in the top left that says booting recovery, then let go. It should boot to recovery at that point.

[Q] Boot Loop at "Recovery Booting"

I was preparing to switch to Beans new deodexed and I was at step 2, I went into recovery mode on my phone so I could flash it and all my phone will do now is loop at the "Recovery Booting"........ How can I stop this and reset my phone? Hopefully y'all can see the pic ok. I had to use my webcam in my laptop to take it since I couldn't do a screen shot.
Thanks,

Same issue here cept I can get into download mode. Had safestrap NC2 4.4.2 Over 4.3 Rooted. But It just chain reboots into recovery. I'm debating to just start over ( don't want to) But I wonder if there's another fix.\
**Update**
I found a workaround.
Pull the battery put it back
Then Press and hold power/home/volume down to go into download mode then Cancel it to exit and it should boot as normal. Piece of **** boot loop You can then Select in safestrap in the OS to reboot into recovery then it will try and be stuck in the loop again. Then pull the battery then put it in download mode again then cancel and it will boot into the recovery where you can wipe/etc.
For everyone running nc2 firmware. The stock recovery (sammys recovery) is broke. Booting into nc2 recovery will start bootloops. If you do. Pull battery put it back and boot directly into dl mode then cancel and the phone will boot like normal. For those of you on nc4 firmware (latest ota) if you flash a custom rom and get the blackscreen trying to boot you will need to reboot to download mode and odin the nc2 kernel. Then reboot and it will fire up.

You are a saint! Just saved me from a laborious work around. Why isn't this the standard advice around here? Such a practical solution.

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.

Flashed TWRP, now can't flash back to stock recovery. Help...

I updated to Lollipop using adb and stock recovery. That worked great. Then I flashed TWRP and made a nandroid backup. I have not rooted again since I'm switching to Nexus 9. So I want to reflash stock recovery, but I didn't save it.
I have the original stock recovery from the mantaray-lrx21p factory image, but when I flash it and boot into recovery, it's just blank screen. I'm assuming the OTA update also updated recovery? Does anyone have a copy of stock recovery after the OTA Nexus 10 update I could borrow?
Thanks,
Steve
Interestingly, I find that if I flash the stock recovery from mantaray-ktu84p, then it works. So it's the stock recovery in mantaray-lrx21p that just shows blank screen...
Same issue here to? Fix
Galaxy 6s Os 6.2.8▪Ss° Pen
I think the fix is we need to get someone with the latest Lollipop patch to extract and give us the recovery.img?
When blank screen appears, press power button for few seconds until the green robot appears, then press power + volume up ( or down ). the stock recovery menu will show up
I don't get any robot when pushing power button on blank screen. After 10 secs, device reboots. Are you sure it works like this now?
Well this is strange. I started all over with ktu84p, then applied the OTA lrx21p update. After the update, the recovery still says ktu84p so it did not get updated by applying the OTA update. Is that what everyone else sees as well? If I flash the recovery.img from the lrx21p factory image, then I get the blank screen instead of robot.

lg v20 h918 twrp bootloop

so I was having some battery issues and wanted to reset. i for some reason went to settings reset instead of booting to twrp to reset. nonetheless it booted to twrp. I wanted an all the way clean data install so I hit format data and rebooted. now it just keeps booting into twrp. i restored a backup which sys successful but it still goes back to twrp. I can get into fastboot, recoveery. and download mode. I just cant boot into the system.. any help would be appreciated. with no kdz available I dont know what to do..
EDIT FIXED: so apparently you cannot boot to twrp to reset from the factory reset screen on the phone. once I booted to twrp manually and rebooted it started up. really weird.
having same issue with us996 now cant boot to system followed root instructions to factory reset now i cant boot to anything other than twrp whats the button combo and chould u provide detailed instructions please?

Press power and volume down at same time. When lg logo appears realeasw the power button for 1 sec and repress. Then when you get to the all white reset screen press yes and yes again on the next screen. This will get you back into twrp. You might need to reflash the recovery img(not sure, but I did). Restore your backup or whatever and then reboot system. Might have to format data within twrp prior to restore. Think I did that too.
pretty sure im screwed until a rom is released i tried what you said i chouldnt get a white screen to appear still went to twrp directly and it seems i accidently deleted my restore point >< can h918 flash on us996? even though its tmobile?
so i got it booting but it keeps rebooting after a getting to home screen a notification pops up and says android is upgrading when finished it reboots

For reasons I'll never understand, I ended up in this situation with my H918 after doing an accidental factory reset (tried entering TWRP but TWRP wasn't installed... oops!) and re-rooting. After installing TWRP 3.0.2-1, I was completely unable to boot to system. I tried reflashing various stock partitions and a custom ROM, relocked and unlocked the bootloader a few times, and wiped/formatted/reparitioned the crap out of the poor thing. In the end, the only thing that worked was to flash TWRP a second time. Go figure.
Thanks for being so thorough in describing what you tried on the road to success!
I keep getting sent to twrp. Not sure how to fix it. I can't boot android. Have tried reinstalling roms. nothing working.
when i use button combo to boot into twrp it go to twrp then starts to boot up phone and sits at lg logo after i tried restore a backup. even after factory reset it loads 100% but never boots up

since you're having this problem with TWRP , it means you've rooted the phone right?
asking cz i'm looking to get the LG V20 but don't know about the risk of it bootlooping itself, without rooting or anything like that, like it used
to happen on lg g4 and g3.
Thank you

You most likely don't need to go through all of those hoops in the link above.
Have you tried power on and volume down to go through the factory reset screens.
A bunch of us had this problem and it was because an update downloaded on it's own and the bootloader snoops it out and forces recovery to boot.
Just do the volume down + power button - as soon as you see the lg logo release power only then immediately re-press power and continue holding power and volume down until the factory reset screen pops up. Select yes and yes, (don't worry - if you have twrp recovery it can't reset). It will boot you into TWRP and I'm pretty sure it will delete the update files in fota folder.
In TWRP select reboot - system and it should boot normally like nothing happened.

I ran into this issue and did as you wrote to re-flash Lineage 14 and it WORKED! Took me hours to get to this post, but after some searching around i'm so relieved and so much less frustrated! Thank you for your input!

Tried to root, recovery flashed but didn't boot, now phone won't reboot.

Hey guys and gals, I decided to take my new PH-1 and root it after getting the latest OTA (this is an unlocked Sprint variant). I flashed the twrp for my build and there was an error, tried it again and the same error so I rebooted back into fastboot and it flashed but I didn't reboot into recovery. Flashed it again and booted into recovery but it was just a black screen as if the phone wasn't turned on. The closest I've gotten to recovery was the android laying down and it said "no command" but I forced a reboot at that point (I think I could have pressed up on the volume and pressed the power button to get to it from there but I haven't been able to get back to it).
I ended up flashing a modded boot image for root with Magisk 14.3 and that worked but I can't reboot my phone, it just goes to the blank screen like it isn't on and I can start it up again by holding the power button down for 15 sec. and it seems to function fine but I can't flash the OTA file to go back to complete stock or to go to the Oreo beta.
If anyone could give me some insight into this problem or a way of fixing it I would grateful, thank you.
