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.

Flash the oreo update zip from westwood or zefie. You can find it in the rom and development section. Search for v20a

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:

Hey,
Very strange query but here goes. Rooted phone a while back and installed CM13 along with recovery. Was trying to update TWRP{ by downloading .img from their website, went to flashing, selected the file and hit recovery. Said it was succesful so attempted to reboot. Plugged in to charge and was charging but when I tried to switch it on, it was stuck in Cyanogen Bootloop (blue alien stayed on the screen for 10+ minutes). Tried rebooting to recovery by hitting power + volume down and instead of booting to TWRP, it takes me to a Cyanogen recovery screen where I see the following options:
Cyanogen Recovery.
- Reboot system now
- Apply update
- - -apply from ADB
- - -choose from emulated
- Factory reset
- - -system reset
- - -full factory reset
- - -wipe cache
- Advanced
- - -reboot recovery
- - -reboot to bootloader
- - -Wipe system partition
- - -view recovery logs
Here's what I tried as troubleshooting. Tried to do a system reset, factory reset and wiped cache and tried to restart my phone but no luck. Still stuck in boot loop with CM logo. Tried to reboot to bootloader but the screen is stuck with the 1+ logo for about 5 mins so gave up on that.
Basically, right now I can't access anything on the phone, can't find any way to reinstall a ROM and when I plug it into my Macbook, it is not recognised. So I'm screwed sideways. I had TWRP recovery set up so I have no clue how this happened but can anyone please help me with this.
If data isn't at risk try the Qualcomm recovery tool one the oneplus forum it's by nammand bhal (definitely butchered the name) but all data is lost and resets the phone to out of box conditions locked bootloader and Oos 2.2.1 so this is often a last measure (tool is Windows but may have Mac variant and the file is quite big)
My suggestion is to try to boot to bootloader again and flash TWRP
hmm mac book I don't have much experience with those
If you have a Windows pc you can use adb or on Mac if it has it. Also when it come to being found by a computer in recovery it should but again don't have a mac
CM13 replaced your TWRP recovery with Cyanogen Recovery.
Try to boot into fastboot by holding volume up+ power buttons. If successfull, flash TWRP Recovery, boot into it, wipe everything and do a clean install of the ROM.
Macbook won't detect your device unless it is booted up, in recovery or in fastboot mode.
Doesn't it detect while you are in CM Recovery??
Try selecting Apply Update and Update from ADB. It should detect the device atleast now. If yes, try sideloading.

I knew I would regret getting that macbook at some point
Borrowed a friend's PC and was able to flash TWRP recovery. Was then able to boot into it and do a clean install. Ended up installing Oxygen OS this time. Do you know why this issue occurred so I can research how to prevent it next time.

Actually I don't think the issue was with the Macbook since I have unlocked, flashed custom recoveries and sideloaded ROMs on several devices including OP2, OP3, Nexus 5, etc on mine. It might have been some accidental flashing error, which unfortunately ended up bricking your device.
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!
I have a Huawei P9 Lite and i have installed twrp and android 7.0 on it. Now I want to install Google assistant, but when i try to boot in twrp recovery (volume down + power b) it shows me the screen where it says ''Installing update'' and then freezes at 5 % so i have to hold my power button to power off the phone.
If I dont try to run in the twrp, phone works just fine.
I apologize for my bad english.
Hi there,
I will move your thread in the correct forum dedicated to Huawei P9 Lite for more relevant answers.
Good luck
Bump..
Just to state that I am in the same boat here; as I am facing the same issue. Here's what happened in my case (using a guide found here at XDA-Developers):
-- unlocked the bootloader
-- booted to bootloader and flashed twrp
-- used adb to reboot to recovery (adb reboot recovery)
-- used twrp recovery to flash nougat update (two zip files, one ~1300mb and second ~680mb)
-- had some errors that were expected, the guide said ignore them and reboot after both zips have been flashed.
-- the flash overall was successful as the phone booted in emui 5 with android nougat. However, there was no virtual keyboard; so decided to do a factory reset
-- rebooted to recovery, but this time, the phone booted to huawei erecovery
-- did a factory reset, but to no avail
-- now, i can't boot into twrp to flash anything else. booting into bootloader and using fastload to flash recovery image is successful, but the phone does not boot to twrp recovery; remain stuck on "your phone is booting up" (or something similar).
My phone is not bricked, as basic telephony, wifi and built-in apps are working fine. But, without a keyboard, its pretty useless for everyday use. Any help in this matter will be appreciated.

This seems helpful; but how can I flash recovery if I can't boot to fastboot?
[Update] Oh, got to fastboot, trying the suggested recovery now.
Fixed
Fixed using the suggestion above. Thanks.
Hello, i had a lot of troubles with battery drains recently, by curiosity i wanted to restore my stock backup.
So i did and the phone was stuck during rom boot.
So i wanted to go back to TWRP to fix things but instead it went back to stock recovery.
Okay, so i wanted to flash TWRP again but after flashing the recovery.img,
nothing happens when i enter fastboot reboot
I forced shutdown and re tried many times with other twrp files, always the same issue i cannot reboot with the flashed recovery ! ! !
please HELP :angel:
To boot to recovery, shut down the phone, press volume up + power button, when the phone vibrate release the buttons and it will boot to recovery.
The command "fastboot reboot" will just reboot normally the phone.
sorry but my problem is that i cannot reboot in twrp anymore, it always reboot on STOCK recovery !
dunno what to do i got to meet foreign customers tomorrow without my phone i dunno how i'll do, so unlucky it happened to me today
i even tried flashing on another computer, and trying to restore with stock recovery or huawei app but none are working.
to make it clear, i can just fastboot.
so what should i flash to restore/unbrick my phone ? don't care if i lose data, just need to call tomorrow !
edit: some folks say to put update.app in load folder on sd card then boot with the three buttons but which update.app file should i copy ? i got a VNS-L31 should the SD card be in FAT32 ?
Are you sure you flashed TWRP? Try to download it again and flash it from fastboot mode.
yes sure i did it like 20 times this afternoon, i'm trying to fix it for 5 hours lol
in fact i just was able to boot the restore .app while booting with the three buttons, it's installing updates, hope it will fix all the partitions/recovery/boot/system... and all those necessary stuffs
edit: finally huawei animated boot logo is showing UP !
On which firmware are you and which TWRP did you tried?

i was using meticulous TWRP v3 and some of his builds for several months and i had trouble with those roms.
so i restored my stock backup and everything was not working anymore, each i tried flashing it always went back on stock recovery a every reboot, impossible to flash twrp anymore...
looks like the phone is stuck in a boot loop lol pfffft
edit:
FYI what i just tried is restoring this image http://consumer.huawei.com/lk/support/products/downloads/huawei-p9-lite-lk.htm (the first one ASIA) but the phone is still booting looks like a fail, could it be incompatible ?
I see.
If you managed to restore with the update.app and the 3 buttons, everything should be fine. It will take some time to boot up, so just wait for a while. Also the bootloader probably re-locked so you will need to unlock it again.

it can relock ? i will check !
if it does not work should i fast boot flash system.img, recovery.img, cust.img, cache.img and boot.img ?
I think the best thing to do should be a factory reset from recovery, stock is fine, then reboot and wait for 15-20 minutes. If the update.app succefully installed there should be no problem

You're welcome
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)

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
