I had already installed TWRP and decided to wipe the whole data from my phone, thinking that it's going to be the same as a factory reset because I want to reset my phone. Phone startup went well, no hiccups or anything. Then I decided to flash TWRP again. But I never managed to actually install it. I follow the manuals from here and here, but I somehow always can't boot into the recovery. I use the same ADB and fastboot I used to install TWRP from before. Flashed .img, reboot, can't enter the recovery, starts over again, and this goes on and on. Until now, whenever I want to boot normally, I keep getting stuck at the "Zenfone" logo screen. The only different thing that I could think of that caused this is when I decided to use Universal ADB Helper, because maybe it'll work there i thought, and I flash the twrp.img using the "Flash Recovery via fastboot" command. If there's anything that could help me, even if it meant resetting the phone again, I'd very much appreciate it.

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
Well, while trying to flash a custom rom on my phone I ended up here and tried many different methods.
First after I installed TWRP on the phone I tried to install the rom and it told me it failed. So then I wiped my phone and tried again, still failed. Then I got stuck in a bootloop. I did a factory reset and was able to get into TWRP. So I wiped everything and it asked me if I wanted to root my phone. I said yes and now the boot screen stays forever and the notification led never turns off. So I did factory reset and tried to run a command on terminal "dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota" it still did not boot up.
I have tried flashes the stock and I can't get oceanhost.eu and storagecow.eu to load up.
Please I would appreciate any help, is my phone dead? I can always boot to TWRP as long as I factory reset.

Sorry that I didn't mention this but, I am runnning a LGG2 802 16gb
I have unlocked bootloader, flash modified boot.img and recovery but when I boot the device I get 'Your device is corrupt and may not work properly' I then get stuck on the google boot screen. When I go into TWRP recovery it cannot mount anything so I cannot even perform a factory reset.
Please help
did you make a back up?
I didn't unfortunately, I can get into recovery and as long as I leave it as 'Read-Only' it seems to mount everything. I think I need to get a stock image.
Resolved - used a Toolkit to go completely back to stock, kind of scared to try again now.
Follow directions and that won't happen again. Make sure you are on the correct version MDB08K BEFORE you start (you have the OTA), format not wipe in TWRP and you won't get caught in the boot loop.
Failing to do those two things will put you in a boot loop.
What toolkit did you use because i myself have this issue with my nexus 6p

That warning is normal, and should be ignored if you want unlocked bootloader, custom ROMs, etc.
Here TWRP couldn't mount because you forgot to decrypt after flashing the modified boot.img.
If you have further issues, let me know.
A quick advise - Avoid toolkits. They are handy and easy, but if something goes wrong, it will be hard to track down the cause. On the contrary, doing thing manually, will not only make it easy, but will also help you learn more about your Android, and how it works.
When I go to put the official twrp on it doesn't stick after reboot. before reboot I can't flash anything either like magisk. Nothing shows inside the folders and after I reboot and go back to twrp it shows no command
Me too. I've flashed twrp-sanders and also twrp-potter. The phone will never boot into twrp recovery on its own. Also, when I fastboot boot recovery from PC, either version of TWRP loads splash screen but is frozen and requires a hard reset.
The phone is unlocked as it indicates this on boot up.
Only once after the first attempt of flashing twrp-sanders recovery did the phone boot into twrp recovery and I flashed Magisk from there. Since then, no dice
Any ideas or direction would be greatly appreciated. Thank you
Got it to finally work. I started over by flashing "twrp-sanders-r2.img".
Make sure the first thing you do after flashing the recovery is to push volume button until you see the recovery option. Then press power button to select it. It will take several seconds before you can interact with the program.
I made sure I had the magisk.zip ready to flash first thing I did.
If you don't go to recovery immediately after flashing the twrp, you'll have to start over.
I hope this helps
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"
