So I'm trying to install TWRP through ADB, but every time i reboot my phone into bootloader, adb disconnects and my computer does not recognize it. This problem only recently started. I am on the official version of Nougat. Does anyone else have this problem and know a solution? Thanks!

ADB is only supposed to work while the phone is loaded into the OS or in sideload mode. In bootloader mode, only fastboot will work.
So the correct command to flash the recovery would be:
Code:
fastboot flash recovery recovery-name.img
Example:
Code:
fastboot flash recovery twrp-3.0.2-1-angler.img

sorry my mistake, I meant fastboot. The problem I'm having is that i cannot even enter these commands. It disconnects as soon as it goes into bootloader mode.

Uninstall and then reinstall the drivers by connecting the device. Also, try switching ports.
as weird as it may be, try changing the cable also
I was getting fastboot errors when flashing recovery few days ago, and just by curiosity,I tried with another cable.. it worked with no errors
one more thing.. if you send an adb command to reboot in bootloader, then you have to physically unplug your phone from the computer and plug it back again
only after that, fastboot devices command will show your phone in fastboot mode

I tried all of this but it still doesn't work. It was working just a few weeks back when i installed nougat, but now it doesn't work. It's so strange. Any other suggestions?

Does charging work fine? And did you try using a different computer? Try charging the phone with that cord that you're using. (even though it's really short, see if it charges steadily)

Try updating adb drivers. and make sure you're using data transfer cable, there are many charging cables out there.. those will not read your phone in transfer mode, I've faced this, solved by purchasing new data cable.

Okay so I flashed a rom and im stuck in a bootloop, but I cant get into recovery to restore a nandroid. My power button receded so as soon as I put in a battery it immediately turns on. But if i go into bootloader, not the power button nor the volume keys will work. So I cant get into recovery that way. Is there any other way like with adb in bootloader? Or am i screwed lol.
Thanks in advance for help, I could really use it.
adb reboot bootloader
adb reboot recovery
It should be obvious what they do. Bootloader won't do you much good without a power button.

if you are in bootloader mode, make sure the phone says FASTBOOT USB somewhere on the screen when connected to the computer.
then type
Code:
fastboot reboot (whatever it is you want to reboot to)
adb only works in recovery or android itself.

Just boot the phone in the regular way.
While it boots, in bootanimation or even a bit before that, execute "adb reboot recovery".

Bump.
I can't get it back into fastboot usb either, I think the power button fixed for a second before and selected fastboot.
Do you have a warranty on this phone?
If not, you may want to open it where you can access the power button more easily.
Before you do that though, get it caught in a bootloop and try adb reboot recovery. Reboot and try again at a different point. It should work eventually. Persistence might pay off.

Since you're in the bootloop, your device is connecting and disconnecting. See when it connects (easily recognized Windows "USB device connected" sound), then execute "adb reboot recovery" until the command catches or the phone reboots. Attempt several times.
If it won't work - open the phone and fix the button.
Please help! I am somewhat a noob and I have a bricked Moto X pure. My phone bricked when i was installing supersu from the twrp. Now it can get into bootloader but all the data on my phone is deleted including twrp. For me this would be an easy fix but of course, my phone does not sense the usb cord. I have tried a couple usb cords to connect to my pc but none of them will work. Am i stuck into a paradox if i dont find a way to get my usb cord to work? Pleaser Help!!!

Honestly, if your phone can't talk to your computer with fastboot in the bootloader, your pretty much screwed.
How did you root? What specific version and steps did you take?
I used the hiensberg guide https://forum.xda-developers.com/moto-x-style/general/guides-how-to-guides-beginners-t3200808
What do you think is the best option from here?
Are you trying to get into fastboot with it connected to computer?

No im already in fastboot mode. Im just trying to restore my devioe so that it works. When i power on my phone it displays the unlocked bootloader warning then goes into fastboot mode. The screen reads-
"Start up failed: Your device didnt start up succesfully. Use the software repair assistant on computer to repair your device. Connect your device to your computer to get the software repair assistant. AP Fastboot Flash Mode (Secure) Error: failed to load kernel! Fastboot reason: fall-through from normal boot mode"
On top of this my device will not connect to my computer through usb and all my data is deleted included twrp. I really dont know what to do

No... Factory images and custom recovery can only be loaded with fastboot.
So if you connect you phone in the Bootloader to your PC and do "fastboot devices" what is the response? And what OS?

Do you have this when you boot into bootloader/fastboot mode?
Power off, vol - & power?
I think you can't repair it in home.
It looks like you flashed something wrong or something in wrong place.
F.e.: twrp into boot partition.

Hmm i just tried that and no device showed up. I think after this im just gonna buy a fresh usb cord and if that does work i am scarping this phone. I overall had a very bad experience with this phone anyways. Ill get back to you once i try.
But you had unlocked and flashed TWRP, right? So fastboot worked at one time and you understand how to use it, generally at least?

Yes fastboot worked at one time and so did twrp. I had reached the last stage of rooting which was installing supersu when the whole thing crashed. After my phone stopped working i went into recovery mode and used twrp to format my data and delete everything. Since then i havent been able to plug in a usb or go into recovery mode

Hi, my 6p will not show up on my PC. Have tried installing drivers, different PC, different cable but nothing works.
I recently upgraded to android O. I extracted the files from system image and flashed boot image, vendor image, and system. But now when I try to go into recovery it says no command and I lost root access but my bootloader is unlocked. I never flashed the recovery thinking TWRP would stay intact but I guess I was wrong. Normally I would just use ADB and fix it but hence my problem. Is there any way to root without PC or any way I can fix my situation?
Having the same exact issue here, hope someone has a way to fix it.

So your phone will boot into the OS, or not? If so, make sure USB debugging is set to "on" in Developer Settings. Can you put your device in fastboot mode by holding down the volume down button before hitting the power button? The "no command" means you are in (stock) recovery. You then have to hold the power button down while using the volume buttons to navigate. Power button is confirm. Get your phone into bootloader mode and use ADB to flash TWRP again. @meoshe

Yes phone is working fine. Debugging is on. Can't use ADB phone does not get recognized by PC, only charges. Dint even get the pull down notification once I connect usb. Tried changing connection to mtp in developer options also. Nada. Nothing works to fix it. I'm thinking my charging port might have something wrong with it I don't know. I'm stuck not having root atm.

Gotcha. What about the other points? Entering bootloader mode from a powered off state, and that you are in Recovery mode (no command), and navigating thru it with the power+volume buttons?

Yes that works. Thank you. But still can't root phone and can't flash TWRP. Was looking at a root APK but not sure if they will work with O. If I could root then I could install TWRP thru it's app but I need root for that.
You can't root the phone until you have a working custom recovery. Focus on either fastboot flashing or fastboot booting TWRP.img

How do I go about fastboot booting TWRP image?
I can get into bootloader from phone but I can't use a PC.
I did read your OP, but this sounds like a driver issue. There are two drivers that need to be installed first the USB and then fastboot. Since you can boot the device and use it, maybe you should try NRT by Wugfresh to install, test and confirm the drivers are properly installed. Booting or flashing TWRP is just a different command. Instead of fastboot flash recovery twrp.img, you use fastboot boot recovery recovery.img. The NRT toolkit can also either boot or flash a recovery image.
EDIT: Also try "Revoking ADB debugging" and re-enabling @sonysingh1983

Hi, just tried the mtp setting in developer options. Didn't get it the first time but now am able to access internal storage. I have plug sound app from play installed and I get a notification sound when plugging and unplugging. First try there was no sound when changing from charging to mtp. Ok after repeating it. Hope that helps.
Just as a follow up I got my win10 pc to recognize my O flashed nexus. I booted into bootloader after I had updated my sdk and drivers through android studio. It recognized the phone but nothing was happening. I rebooted into the os and the access allow prompt popped up on the phone and adb was able to see it under listed devices.
After moving to Lineage 14 from stock 21s, I came to realize Android Pay will not work if the bootloader is unlocked.
So I went to go and lock the bootloader (with TWRP and Lineage still installed) and for some reason when I do a "adb devices" the phone is not seen.
I uninstalled the driver, reinstalled.
Tried unplugging, launching ADB, then plugging in..
Plugging in then launching ADB...
Then i put ADB on my wife's laptop (A PC I have never plugged the leeco pro 3 on to), then plugged in for the first time already in fast boot. Still no dice.
Anyone have any ideas?

If you boot into fastboot mode (Volume Up + Power), does the phone show up in 'fastboot devices'?
If so, then IMHO you should be fine in catastrophic situation.

Do you have adb drivers, and did you try completely deleting your device drivers from Device Manager, then reinstalling them by plugging your phone in via USB Debugging? Are you using the platform-tools package? Did you connect via USB Debugging, and did you authorize the computer (the message should pop up on your phone)? I can't fathom why your phone wouldn't be recognized...

Yes to everything, lol
And when I am connected to the phone while in the OS, ADB works fine, shows in when I "ADB devices"
Where'd you get your phone from? Banggood, Geekbuying, Gearbest? Did it come with a vendor ROM? Did it not pass SafetyNet on the original ROM it came with?
Are you following these instructions? Of course, replace the required stock ROM with the one for your version (x720 or x727). So does the issue come up when you reboot the phone via ADB while in the OS?
In any case, try asking on the http://www.leeco.re/ forums as well.
I finally managed to switch from (rooted) Nougat to Oreo (rooted) .
Now I'm facing an issue with fastboot command not working.
ADB works ("adb devices", "adb reboot..." commands are ok) but fastboot always fails.
The commad itself is ercognized by the system but it aways fails in executing the command ("waiting for the device...").
I've tried several ADB/Fastboot install methods, always the same result.
Is there something I am missing?
fastboot mode usually has nothing to do with the android flashed because its a mode triggered out from Any android.
however some days ago my PC suddenly stopped recognizing device ..
All I did changed port and cable! .. and it worked fine!
please try that (if you havent already )

Check the device manager on the pc if using Windows before anything else. It's likely the fastboot driver, select it press update and point it to the correct driver. It should be installed on the computer already so you can just choose the correct driver.
Just to share that the only way I found to get fastboot work is to install flashmode and fastboot drivers from the installer provided by flsahtool in the drivers folder.
