While using the PA Updater app to upgrade my rom, the app attempted to reboot into recovery to run an openrecovery script. While doing this, I believe it set my "reboot mode flag" to recovery.
The tablet boots with the Google screen and then shows the TWRP splash (I'm on version 2.6.0.0), then it reboots and starts again.
I am able to get to the bootloader, but even if I press start or recovery mode it reenters the boot loop trying to get into recovery. In the bootloader was where I saw the reboot mode flag set to recovery. Is there a way to use fastboot to remove that or am I just going to have to do a wipe with fastboot?
It happened to me once. I pushed the power button for 60 seconds as it supposed to do a kind of battery pull, and it worked.

I've done this twice to my nexus now and I think I found a reliable way to restore to running condition. YMMV
1)Boot the nexus into fastboot (power and both volume keys) when you power up.
2)Attach your usb cable from the PC (or MAC I guess, dont have one to try)
3)start WUG Nexxus Root Toolkit. 'Launch' advanced utilities.
4)Test your fastboot with Quick tools. check the button at Fastboot-Bootloader and click 'List Devices' if the box that pops up is empty then fastboot isn't working (I can't help you there and it must be working to continue).
5)If fastboot shows a device then go to "Boot Temporary" and click 'Custom Recovery'.
6)I selected 'Touch TWRP' but CMW may work as well. This will reboot you into (temp)TWRP and from there you can force a reboot that will reset the 'Recovery' flag that has locked your bootloader.
7)Give it a few minutes (be patient for 5 minutes) and hopefully you reboot to where you were prior to this mess.
Long time lurker and couldn't fix my fails without everyone here.
Thanks to all.

I had the same thing happen to me (though i updated from stock 4.4 to 4.4.2 [and i had twrp installed]). I tried reflashing to stock recovery and a few other things but same problem, it kept booting me into stock recovery. I know this is going to sound crazy, even stupid, but just letting it sit there for 5 minutes (at the stock recovery screen) let it work... I was searching for more things to try and it just started booting.... Checking the bootloader again showed the reboot mode flag set to none.

I guess mine worked because I was still on stock bootloader and adding TWRP was an important key but the 5 minutes seems to be the solution after all the rest.
recovery boot loop:- Is coz, one of your partitions would be facing problems while mounting.. So Wipe the Partition and Format it with Ext-2 file format. and reboot the Mobile. Then it'll stops rebooting.
Do you have a Samsung device?
Be warned - there is no such thing as fastboot mode for most Samsung Galaxy devices - you'll be wasting your time doing this and typing "fastboot devices" for many hours!
If you have problems with your recovery, it works to just reflash the CF-autoroot kit, which happens to flash the cache partition too. My problem was similar to the OP's - a bootloop with TWRP's obviously buggy OpenRecoveryScript, which was installing a ZIP file over and over again.
If you flash the CF-autoroot specific to your device, TWRP will be gone, but the phone will boot normally again - with all your data on it - hooray!
Then you install TWRP or CWM recovery as you did originally.
Stay away from OpenRecoveryScripts! I'll be installing a ZIP file in the traditional, manual way from now on, from an external SD card so I can remove the card if I get another TWRP boot loop.

How do you install cf-autoroot when stuck in a boot loop with samsung galaxy S device if there is no fastboot?
My phone is stuck in bootloop too. It shows Twrp at the starting and then restarts. What am i supposed to do? I need help ASAP please
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!
Hello, ive unlocked my bootloader on my h870 and ive flashed twrp. when ive just flashed it i was able to boot into twrp but now everytime i try to boot into it it wil wipe all my data with the stock lg recovery mode can someoneone please help me? Thanks! Just got the phone a few hours ago
You have to install a custom rom or root to make twrp permanent, if you don't do that it will install always after the first boot the stock recovery.

When you have flashed twrp, you do the buton combination to enter twrp, if you fail to enter twrp a the phone boots into system the stock recovery will be reflashed so you have to reflash twrp.
Try making these:
When you are in the bootloader after flashing twrp press button down+ power button. When the screen turns off quickly stop pressing power button and quickly press again until the lg logo appear.
When the lg logo appear stop pressing power button, quickly press again and stop pressing the power button and press again quickly until you see twrp logo.
These method works for me for booting twrp easily
The stock recovery appears but you have to select the factory reset option and it will boot into TWRP

Unfortunately still not succeeded after trying all the solutions i've found here
Hey, i have the same Problem, my TWRP broke, i can't boot into recovery and my Device ist not listed in fastboot mode. Can someone help me out?
I get the ring in windows when i plugin but its not recognizing.. Can someone pls help me out?
Okay, I'm going to try to explain it, and see if I can succeed where others have not.
You install TWRP by booting to bootloader and using fastboot to push a new recovery:
Code:
fastboot flash recovery twrp.img
It seems like you accomplished that successfully. The next step is to immediately boot to recovery; do not boot the phone to system first. You will get the factory prompts for wiping data, but it will not actually wipe your data this time. Instead it will boot to TWRP.
Now, while you are in TWRP, you need to either root (flash Magisk) or install a custom ROM. If you do not, your next boot to system will remove TWRP and restore the stock recovery. If that happens, then the data-wiping prompts the next time you boot to recovery are real and the phone will wipe. So you MUST - must must must - root or install a custom ROM while you have TWRP up, in order for TWRP to persist.
If you have already experienced this problem, you need to start over at the beginning; flash TWRP again, and then follow the rest of these directions.
Maybe this will help clear up the problem for you guys.

Oh my god, i really really thanks for your reply, you're so fre*king good. U made my day.
Guys a little help
I only manage to see the TWRP welcome screen and the the phone automatically reboots to system
I can't get to see the TWRP menu at all!!
WTF is going on?
I have repeated the process many many times and always the same. What i am missing here?!?!?
me too when it boots in twrp only showing logo then it reboots in system what are wedoing wrong?
Got the same problem. I unlocked Bootloader, checked if unlocked (yes). After flashing TWRP i see the TeamWin Screen and phone boot again. There is no TeamWin Menu.
A try with an older TWRP-Version and flashing via fastboot with another PC does not work too.
Anybody an idea?
Did you guys manage to fix it?

With 3.2.1.0, 3.2.2.0 and 3.2.3.0 it only briefly shows the TWRP screen and then boots into system anyway.
With 3.1.1.0 the key combination to boot into TWRP as with the other versions above simply doesn't work, again it directly boots into system without even showing the TWRP screen.
I'm stuck with a resetted phone because of this bull****, because some instructions said "oh, the reset dialog will not really reset your data..." - yeah thanks for nothing, buddy.
So what now?
EDIT: I got it working using TWRP 3.1.1.0, but the same version from the OFFICIAL site didn't work, as I described above.
The only 3.1.1.0 TWRP that works with my phone is the one from this Link: http://downloads.codefi.re/rashed/g6/
(which is linked ... somewhere here in the Forum, don't remember which thread)
So a while ago I had dirty flashed the Oreo update from this link: OREO open to give it a try and see if I could actually get away with a dirty installation. Phone was working ok but battery drain has been enormous, around 30-50% worse than with Android 7.1 especially on idle so I thought ok time to do a proper factory reset by wiping everything (Dalvik, cache, system).
Now, I selected Factory Reset from within the OS (not TWRP) but during the first reboot it booted into TWRP asking me for decryption password, I did a wipe so it forgot all about it but now it only boots into TWRP no matter if I do an Advanced Factory Reset wiping everything via TWRP's menu, phone starts, shows the LG logo for a couple of sec and then TWRP screen shows up.
I am thinking I should flash a stock Oreo recovery in order for the boot to the OS but not 100% sure if this will cause more trouble.

Thanks but being impatient, I tried flashing the stock recovery. This seemed to free the booting and reset process, phone showed the LG logo, then for 2 seconds "Deleting" then LG Logo again and I thought the factory reset was in progress. After like half an hour still stuck in LG logo I realized I've probably soft bricked it. Phone only starts and gets stuck in LG Logo. So I entered bootloader and re-flashed TWRP but unfortunately now I can't find a way to boot into recovery (the irony). Phone just starts and gets stuck in LG logo forever, only thing i can do is use Power+Vol down to reboot into bootloader but no way to boot into recovery or even shut it off. Any way to enter recovery at this state and flash the OREO zip?
I realize I should have just waited for instructions but coming from consecutive unlocked Nexus devices i thought the steps and processes would be similar...
Try to discharge the phone completely (to shut it off) and enter download mode (I don't know any other method to do it). With LG UP flash stock kdz from your model, if you search a bit you will find it. This should work. If it don't work I've seen a couple of posts with the same problem as yours, search for the solution there, but if you can enter download mode it should work LG UP.

Thanks for the quick reply. With a bit of Googling I found that you can use volume down to enter stock recovery. This confused me as when I did it I expected to see the TWRP welcome screen. Instead I saw the stock recovery screen which only gives you the option to do factory reset. I did it and then rebooted again into recovery and all of a sudden I saw the TWRP screen! I remember there is something weird with how TWRP sticks to the system or not, again very confusing compared to Nexus devices. Anyway, since I managed to enter Recovery I copied the OREO flashable zip to internal memory and flashed and phone booted fine, now I am waiting to set up a fresh 8.0 installation :good:

OREO flashable zip? I am searching it for a long time, where did you find it?
It seems every ROM I’ve tried installing never boot after “successfully” through TWRP. (Like even 10 mins of waiting)
My idea is that unlocking the bootloader (where it gives you warnings every time the thing boots) has something to do with it, seeing as the flashing guides don‘t mention this in depth.
Factory reset through TWRP after flash, that wipe after flashing that has the button on the finished page
Now it can’t boot into TWRP, or download mode, just stuck between the power screen and black (seemingly turned off)
Did you flash Magisk-v23.0.apk through TWRP?

No, I was following this and this which don’t list Magisk as a step
Would that have been important to do?
Also any ideas on how to get it to download mode? So far it just gets stuck on the Galaxy A20 screen with a warning about it being unlocked, no button combo gets past that, even though it does reboot
