[HELP] Can't get adb to work! - Nexus 6P Q&A, Help & Troubleshooting

Heeelp
I tried to install Cataclysm ROM, and then it went into some sort of installer, after that I tried to reboot, but TWRP said it didn't have any OS?? So i tried to boot it up anyway? but nothing, just stucked on Google Logo. After that I tried to boot into TRWP agian. But then TWRP says "Mount Decrypt Data" and then i have to enter a password?? but i removed my pattern lock before flashing. Because i made a Nandroid and i read i had to remove the password before making a backup. But then i just press cancel. Then it says " Unmodified System Partition" "Swipe to Allow Modifications" and i do that. Now i have nothing on my SD card?? Then i thought i could flash stock through Fastboot/ADB, but now it won't see my device in ADB? I have updated my drivers, both by Google and Intel (Read they helped someone else) But nothing? so i cant retutn to stock and can't boot up.
Please help, highly appreciated
Some how i got i to reboot by an ADB command and then i could flash factory imgs and return to stock.

That very same thing happened to me the 1st time I tried to install Cataclysm. Somehow my SD card got wiped.
I had to start from scratch with the factory image.
I don't know what happened but I have since successfully installed Cataclysm.

[Q] Stuck in recovery boot loop...?

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.

Security error after recovery update

I have a d802 . I had cloudy1.3 and twrp 2.7 installed with autorec. I tried to update it using
dd if=/sdcard/recoveryfilename.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
(from twrp page, with the latest img file).
But I coudn't access recovery, some error about security. Then I shutdown my phone and then it booted fine into system. I retried to access recovery but nothing.
So I decided to return to autorec, I installed it, I clicked "Flash Recovery" and now my phone doesn't boot in any way.
It show "lg security error" and then shutdown.
I can access download mode. Is there a way to fix my phone without deleting everything?
I'm sure the problem is the recovery, I was messing with it, can I bring my phone back and don't delete my configuration, photos, apps?
Thanks
I'm so happy!
I did it!!!
I managed to boot into recovery with the usual combination of keys (with the method that ask you if you want to format, but then you press power and it boot into recovery).
From there I saved everything using adb pull (Just in case). Then I dirty flashed Cloudy 1.3 and my phone is back !
I hope my experience can help someone

(Help) LG G2 cracked screen/soft brick

Bottom half of the screen is cracked which makes it very difficult to " swipe to" do anything in TWRP. I locked my device and was unable to unlock with backup pin because the keyboard does not function properly. So I rebooted into recovery and accidentally wiped Calvin Cache, System, Data, Internal Storage and Cache. Rebooted phone and it's stuck in a boot loop. I tried using adb but I could not get it to swipe into adb sideload. I found that connecting the phone to my PC does open up /SDCARD/TWRP but there are no other folders in /SDCARD. I moved a ROM from my PC to the TWRP folder and was able to flash it but got stuck in boot loop. Tried flashing a different ROM and it shows a new loading screen but still stuck in boot loop. No other folders are being created to SDCARD.. Haven't had this pphone for more than a week.... Was thinking I could maybe flash a non touch TWRP or CWM to avoid having to swipe to get things done and use the hardware keys.. but why is it being stuck in boot loop after it says it successfully flashed the ROM.
I did flash the 30b file it says to flash prior to flashing the 2 custom lollipop ROMs in the tmo dev forum. Any help, links, advise would be much appreciated. Thanks.

Phone only boots with factory mode. I did something wrong.

I have the MetroPCS xt1765 running lineageos 14.1. When unlocking and doing all that jazz, the guide said that you can't flash twrp, only boot it. But I got annoyed that /data wouldn't mount so I just tried to flash it anyway and it worked. On cmd it said that the file wasn't signed or corrupt, but it still wrote to the device. I thought nothing about it at first but when I tried to boot the device it automatically when into twrp. I tried to reboot to system again, and the same thing happened.
Eventually /data successfully mounted and I was able to format it and install linage. I hoped that would fix the problem but it's still there. I believe I would need the stock boot image and probably stock recovery as well. I hope someone out there has these files.
Also when booting with factory mode, my data isn't working at all. The apn setting are right and all, but it's not working.

When it was booting to twrp only, you just select reboot bootloader and in bootloader select start and you will get system. This twrp doesn't read and clear bootloader control block (BCB) properly which causes this. There is a fix. I'll find the link.
Do you mean fastboot/bootloader mode? If yes, try this

Not booting into TWRP

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"
