Hey everyone,
I decided to root my lg g6 and got a fickle. After unlocking the device and flashing TWRP I tried to boot into it (''adb reboot recovery'' command) and it deleted all data and then twrp shows on screen for a split second and almost instantly boots normally into android so I set it up while still being unable to access twrp and any of it's functions. Does anyone have any idea what could be the problem?
P.S. Of it helps: before that i had a problem that every time I tried to use the ''adb reboot recovery'' command the console said ''no devices/emulators found''. After a couple tries I wanted to check whether the phone was connected just to make sure (''adb devices'') and after that it worked and I ran into the problem above.
Thanks for all the answers
When you first unlock BL and flash recovery you have to manually enter recovery mode.
Hold power and vol down till it turns off. Hold same buttons again until you see lg logo. Release power and press and hold again.
Then ask you to wipe etc hit yes both times and it will boot to twrp.
I tried that but it still doesn't go into twrp. After confirming that wipe stuff it just boots into android (without wiping)

You have to flash TWRP recovery and when it complete then use the button combo to boot into twrp, otherwise it will boot and restore the recovery.
flash twrp
button combo to twrp
done
Yes I've done that but the problem still exist.
btw thanks for the help
Maybe try fastboot flash recovery recovery.img
Try the all-in-one tool on this forum
By the way, I am running into the same issue.. I have a LG G6 US997,.. I have tried installing TWRP unofficial ones so many times and every time i manually try to access the recovery.. the phone simply wipes all my data to default
Hello,
I have the same problem. Did anyone figure out how to solve it? I'd highly appreciate any help.
If I try to boot into recovery, it asks me to factory reset, i hit yes twice and then the phone just goes on to boot normally. The data is not wiped but I can't get into TWRP.
If I enter "fastboot reboot recovery" after flashing TWRP it returns "fastboot: usage: unknown reboot target recovery"

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
Hi, everyone.
I have a galaxy s8 SM-G950FD. I have once flashed TWRP and rooted the device successfully.
Then I tried to install a custom ROM but I got bootloop.
After that, I flash official ROM to unbrick my device. But since then, whenever I tried to flash TWRP again I got this message "Verification failed unable to restart your device the integrity verification has failed. You need to reset your device to factory default settings. This will erase all your data."
My device is still working fine but I want to try to flash a new ROM (even if I may brick my device forever). I don't know what to do. Can you guys give me some advice ?
Thank you!
It's quite a simple fix I think: You need to make a backup of the Data partition and then do a wipe using TWRP. This happens because TWRP cannot handle Samsung's Encryption; the only way to bypass this problem is by formatting once again.

But I cannot boot into TWRP. How can I do that ?
If you're stuck in the bootloop you should press the force reboot key combination: Power Down + Home + Power. After the device restarts switch the Volume Down key for the Volume Up key right after the screen goes blank. That should get you into TWRP (if it's correctly installed), otherwise directly into the stock recovery.

I cant flash/get into TWRP. I tried to boot into stock recovery and do a system wipe/factory reset. Then I flash TWRP again but nothing seem to happen. I tried to boot into recovery and it get me to the stock recovery not TWRP.I did unlock OEM, used Odinv3.12, twrp-3.1.1-2-dreamlte.img.tar.
I had the same issue.
After Odin has flashed the Recovery it performs an auto reboot (if checked in Odin). So at this reboot hold Vol up + Home + Power as soon the screen goes of. You need to be quick. Then it should boot into TWRP.
True, Samsung's stock recovery is very persistent lately and if you tick the auto-reboot you have to be very fast in switching to Recovery mode combo.
Otherwise you can choose not to tick auto-reboot, force restart the device after the TWRP flashing was successful and immediately switch to the Recovery combo.
Here you go: two ways of doing this.
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.

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 after stupidly trying to update twrp through twrp instead of fastboot, I can only access fastboot and the universal bootloader installed on the phone. If I don't do anything, the phone simply goes through universal bootloader and I see a small penguin before the screen goes back and I need to restart the phone again. However, in the bootloader I can select to go to fastboot which does work. I've tried flashing TWRP through fastboot (fastboot flash recovery twrp...) and it said success however after clicking 'reboot to recovery', the phone once again just boots to the bootloader and I'm back at square one.
Thank you so much if anyone can help!
FYI, you can update TWRP using TWRP. Nothing wrong with that, I do it all the time. It's faster and easier to do so.
You might have an incompatibility between bootstack and TWRP.
So, please provide us more info.
ROM:
Bootstack used:
TWRP version:
What were you trying to do besides updating TWRP?:
Funny thing... I'm having the exact same problem.
I instaled TWRP (3.1.1-0-9c3b7e99) using the AxonToolkit 1.2.1.
Everything went smooth with the toolkit. I could get into TWRP and did some back-ups (as recommended), then wipe Dalvik/ART Cache, System, data, cache, and finally, try to install LineageOS 15.1.
I used the files:
- ZTE_A7LOSv1_UniversalBootStack.zip
- A2017U_OreoModem.zip
- lineage-15.1-20180810-UNOFFICIAL-axon7.zip
UniversalBoot and Modem were installed correctly, but I got an error when trying to install Lineage. I can't remeber the error number but it said something like: "this ROM is for device ailsa_ii_axon7 but this device is ."
Since then... my phone is in eternal loop and can only get into Fastboot. Can't access TWRP.
Thanks in advance to anyone willing to help me.
Don't mind... I have it back.
After many reboots, It only seems that this is working different with the Universal O bootloader. On the main screen, I tap the volumen button, choose "Recovery", reboot, press the power button on the main screen, press it again, the Linux Pinguin appears, press power button again, and then TWRP is back.
After that, I got to wipe and do the normal ROM installation process.
"your device software cannot be checked for corruption" after installing twrp, help!!
Hello, as title says, following oem unlock procedure, i flashed twrp using fasboot however i could never boot it and now when i try to go to fastboot mode and/or reboot, i see this message "your device software cannot be checked for corruption[...] please lock bootloader"!! Dunno what to do? Please help!
Easy: do absolutely nothing, this is intended behaviour. Unlocking the bootloader leads to the displaying of this message on boot up. Just LG's way of saying continue at your own risk.
Ok so they're even more annoying than samsung..! Anyway, my problem is : how do i enter TWRP..? I flashed again, successfully.. Then i dunno how to enter it!
"The stock recovery appears but you have to select the factory reset option and it will boot into TWRP" i read this. Well it's wrong. Doing so just launch the factory reset!
This video https://www.youtube.com/watch?v=MR4DTgTxhGI shows phone reboots to TWRP after entering "fastboot reboot" (once recovery was flash) : here it just reboots normally!
"Finally Type “fastboot boot TWRP-Recovery-filename.img” to boot your LG G6 into TWRP Recovery" well i thought about that and tried it :
D:\Android\ADB&Fastboot>fastboot boot recovery.img
downloading 'boot.img'...
OKAY [ 0.901s]
booting...
FAILED (remote: unknown command)
finished. total time: 0.925s
I'm very disapointed so far, i expected the G6 to be easier to handle the S7 but it's a pain even before i start using it.. Hell!!
It seems to me that you didn't boot into twrp immediately after flashing it via fastboot. Afaik it's important that you don't boot into OS after flashing, otherwise twrp will be overwritten with stock recovery. I had the same problem when I did the procedure.
The only way I got it to work was booting into twrp via button combo immediately after flash (you know - keep pushing power and vol- until Lg G6 logo appears, release only power and immediately push it again, keep 'em pushed until factory reset, confirm twice and it should boot into twrp). Once you've booted into twrp directly after flashing, it should stick.

After doing this, for TWRP to stick, you have to flash a custom rom, or delete the system/bin/install-recovery.sh to prevent stock recovery overtwrite
