I seems that the right command is "fastboot flash recovery twrp.img"
Unless you wanna install the recovery onto the kernel partition.

@OP: The correct command to flash the recovery is
fastboot flash recovery twrp.img
Please correct it in your post.

it does't work

Because the instruction in first post is incorrect, after you flashed recovery you also need to use this command: "fastboot boot recovery_image_name.img"
This is needed only to boot into TWRP for first time, if you intend on flashing custom ROM's then Format DATA,reboot to recovery again and you can use it normal.

Can't get adb to see my le pro in fastboot

My phone, the LeEco Le Pro 3 LEX727 ZL1_NA US model is on the latest EUI 5.8.021S. I am able to open the adb tools in command prompt and get my computer to recognize my phone with "adb devices", but when I go to the stock fastboot with the Chinese and English writing and use "fastboot devices" nothing shows up. I'm using the latest adb tools and am clueless as to what to do.

Unlock Bootloader - Le Eco Pro 3
If you are not seeing your phone ID in ADB
Did you enable enable Developer options, or chosen MTP?
Its possible that the Android driver driver is outdated, or just try another usb port, preferably in the back of the machine.
Go here to check a whole list of possible causes: https://appuals.com/android-phone-not-showing-up-on-pc/
More than you asked for:
Since you seem to be new to your Leeco phone and new to using custom roms, I am going to go ahead and answer your current question and provide you steps needed to move forward. No big deal, I just copy pasted my notes ( with a few edits)
First steps that you need to take:
1. You will first need to unlock the bootloader :
PHP:
https://forum.xda-developers.com/showpost.php?p=71566961&postcount=203
2. Install Twrp :
PHP:
https://twrp.me/leeco/leecolepro3.html
****** Scroll down to see: Fastboot Install Method (
3. Right now just use ADB. But for the future, I highly recommend that you buy an OTG drive: it makes the whole process a thousand times easier: They are cheap somewhere near $5 and worth ten times that
Unlocking the Bootloader
You can save your self alot of time by looking up how to give ADB system wide privileges: this will allow you to flash files without tying the directory path.
Mauronofrio created a tool called: "TOOL ALL IN ONE"" it's great, install it and check for updates.
PHP:
https://toolaio.tk
The all is one tool is excellent and you can use it to install everything if wanted.
I usually recommend it for novices that can use it to help with unlocking the bootloader and installing TWRP.
The tool will also update your copy of ADB, android Drivers and provide system wide privileges for ADB
LETS RECAP : Choose using the All in One Tool or the ADB Method
**********BEFORE DOING ANYTHING*******************
Make sure you have enabled the developer tools,
Turned on USB debugging
Authorized your computer on your device I.E: “MTP”
Make sure the All in One Tool can see your device
(*) Select your device from the drop down menu, then click check
(*) Choose to install drivers, and set ADB and fastboot privileges from advanced menu.
(*) First attempt to unlock, then check bootloader status
If you have a X727 you will need to flash : emmc_appsboot.mbn from this zip :
PHP:
https://androidfilehost.com/?fid=313042859668275431
Next, choose Recovery flasher and manually select your copy of TWRP
After you have received the success message, I recommend doing the rest of the install manually within Twrp Recovery.
(*) Reboot into TWRP and begin installation of your Rom, Gapps and Magisk.
Using the ADB Method
Install ADB/Fastboot tools on your computer
PHP:
https://wiki.lineageos.org/adb_fastboot_guide.html
1. Make sure you have enabled the developer tools,
2. Turned on USB debugging, and authorized your computer on your device “MTP”
3. Enter fastboot mode on phone (hold power and VOL -)
4. Make sure adb can see your device when you run "adb devices"
5. type: fastboot devices
6. fastboot flash aboot emmc_appsboot.mbn
7. Run { adb reboot bootloader } - No spaces (before/after)
8. Run { fastboot devices } to make sure you see your device
9. Run { fastboot oem unlock-go } to unlock your device temporarily
10. Run { fastboot oem device-info } to verify unlock status
11. Run { fastboot boot recovery_twrp-3.2.1-0-zl1.img }
12. 5. Reboot back to TWRP and begin installation of your Rom, Gapps and Magisk.
13. 6. If you wiped data, your device will now proceed to re-initialize itself as if from the factory
Concerning your device's storage,
When you boot into twrp you will see a message that states that the storage is encrypted.
*****************Important************************ ******************
Ensure that you have TWRP installed as the primary recovery
Ensure that you have TWRP installed as the primary recovery
Ensure that you have TWRP installed as the primary recovery
Ensure that you have TWRP installed as the primary recovery
To remove encryption you will need to format the storage
(Anyone who says otherwise has the X720 and not the X727)
You could also try to skip the formatting step. But you will very likely have permissions issues and get errors and you will eventually have to come back and format ( Again as long as Twrp recovery is install there is very slim chance of ever bricking your phone.
To format the storage
Go to Wipe, choose Format Data and follow the instructions.
This will erase all of photos , music, etc
If you wiped your data partition, you'll need to push the zip file to the newly formatted storage. - This is one BIG reason why using OTG is better. You can use Mauronofrio's "TOOL ALL IN ONE"" for pushing the ROM, Gapps, and Magisk to storage.
Root: You absolutely should root!
NOTE: If you have unlocked the bootloader and flashed TWRP to the recovery partition. But have not yet flashed a Custom Rom the OS will likely reset back to the factory recovery UNLESS YOU ROOT THE SYSTEM. Your device is still unlocked. But the recovery can be overwritten by the stock EUI system, so beware.
Installation of Rom, Gapps, Magisk
Boot into TWRP recovery
1. Go to "Wipe" and then to "Advanced Wipe".
2. Mark "Dalvik / ART Cache", "System", "Data" and "Cache".
3. "Swipe to Wipe" and proceed back the main menu.
4. Go to "Install".
5. Select the ROM zip file and then press "Add more Zips" and select the Gapps zip file, and then the Magisk file.
6. "Swipe to confirm Flash" and wait for some time.
7. After the flashing is finished, just reboot to system.
Finished!
If you need help or have a question message me, I would much rather help you with a successful install versus helping you unbrick your phone.

Thank you for your reply. I figured out the issue. Windows 10 updater wasn't auto installing the driver for some reason even though I have auto update ticked.

You have manually install those drivers usually.
Sent from my LEX720 using xda premium

I have the same issue in Windows 10. All In One Tool sees my x720 in adb mode, but when I switch to bootloader, the phone is gone. Device manager then shows unrecognized android device. I have LTSB version of Windows, so maybe that's why it won't auto install the needed driver. Could anyone point out what kind of driver exactly do I need, so that I can install it manually?

Back to Stock all in one - enable dm-verity, lock bootloader, flash latest OOS

I wanted to create a guide which is as simple as rooting a OnePlus 3T. I don’t know if it will work with the OnePlus 3. I’m not responsible for anything. You’re doing it on your own risk, so only do it if you know what you will do, now! It may brick your device.
This is the way it worked for me. I do not guarantee it will work for you!
READ THE WHOLE INSTRUCTIONS FIRST BEFORE YOU DO ANYTHING​
What we do:
- Flash TWRP
- Flash an old version of OOS
- Enable dm verity
- Relock the bootloader
- Flash the latest stock rom
What you need:
- Computer (Windows 7 or 10)
- USB Cable
- about 1 hour of your lifetime
YOU WILL LOOSE ALL YOUR DATA - ALSO THE INTERNAL STORAGE WILL BE DELETED (pics, music and all the stuff stored there)​
Download to your computer:
Latest TWRP for OnePlus 3T

https://forum.xda-developers.com/oneplus-3t/development/recovery-twrp-oneplus-3t-t3507308
Flash TWRP:
1. Start your phone in fastboot mode (don’t connect to your PC yet!)
2. Open CMD as Admin (Windows start-menu - type “cmd”, right-click, run as administrator)
3. connect your phone
4. rename the file to “recovery” (don’t type “recovery.img” manually, only “recovery”)
5. type command “fastboot devices” -> device will be listed
6. command “fastboot flash recovery C:\Users\...\recovery.img” (the path where it’s stored)
7. done -> boot to recovery
8. disconnect your phone - leave CMD open
Flash OOS 4.0.2
1. Go into TWRP
2. wipe “System, Data, Cache, Dalvik”
3. Install OOS 4.0.2
4. reboot into fastboot
Enable dm-verity:
1. connect your 3T when it’s back in fastboot
2. type in CMD “enable dm-verity”
3. done - keep CMD open and the phone connected
Relock the bootloader:
1. type in CMD “fastboot OEM lock”
2. Warning message on your phone will pop up -> choose “yes” on your phone by using the volume buttons to lock the bootloader (keep CMD open)
Update to the newest OOS via “sideload”:
1. VOL down to boot into recovery
2. choose “Install from ADB”
3. “Upgrade Android from USB?” -> “Ok”
4. rename the OOS zip file to "update"
5. type in CMD “adb sideload C:\Users\...update.zip”
6. done
7. reboot the device - it will take about 10 minutes, DO NOT INTERRUPT THE PROCESS
Finish
Take your time! Don't do it if you're in a rush.
Please give me feedback if it worked for you or if I have to change something.

enable dm-verity doesnt work

Did you check if the device is listed in fastboot?
You can also try the command "disable" and then "enable"
Sometimes you may need to do it first, even if it's disabled

Thanks for your threat. I tried this but had to do a couple things differently.
I think enabling/disabling dm-verity works only with old firmware.
What I used:
* 4.0.2 firmware from this threat https://forum.xda-developers.com/oneplus-3t/how-to/firmware-modem-collection-flashable-zips-t3565535
* latest oneplus recovery and rom https://downloads.oneplus.com/
* the recovery can be downloaded from a link on the bottom of the rom download site.
I started with twrp and a custom rom.
You need usb debuging enabled and adb and fastboot installed
What I did:
* I did a Nandroid backup, and copied the sdcards content to my computer, because the following completely wiped my phone
"adb pull /sdcard /path/to/my/drive/"
* flash 4.0.2 firmware, with trp
enter adb sideload mode in twrp and
"adb sideload firmware.zip"
* fastboot flash oneplus recovery
"fastboot flash recovery recovery.img"
* using onplus recovery and sideloading installed latest oneplus rom
enter adb sideload and
"adb sideload oneplusrom.zip"
* did a factory reset in oneplus recovery and cheked if my phone would boot
* entered fastboot mode
"fastboot oem disable_dm_verity", then "fastboot oem enable_dm_verity"
"fastboot oem lock"
after that my phone got wiped again, and the next boot took a long time
Then the phone was completely stock

Wanted to post to say thanks to roor7 and WhataHulk - had a rooted 3T I wanted to sell following an upgrade (best price requires the phone to have no sign of root!), and this was the only method that worked for me to enable dm-verity.
As a quick note, I followed roor7's guide, but got the same error message as chowchillacharlie. After sme playing about I found the simplest soultion was using the CMD line provided towards the end of WhataHulk's guide, i.e. - "fastboot oem disable_dm_verity", then "fastboot oem enable_dm_verity". For me, roor7's guide swapping the type "enable dm-verity" in CMD with "fastboot oem enable_dm_verity" worked a treat.
Sorry if that is all incredibly obvious to most people!
Thanks again gents.

Hi,
I installed this recovery. But evry time I boot into recovery, it said enter password. Then I installed DM verity disabler. after that installed this recovery zip file. Now seems working.
But, when I checked the developer options, it isn't showing device is unlocked. It says "this device is locked", and it wants me to bind account to unlock.
I checked by fastboot, and it says device unlocked = true.
Why developer options shows device is locked?
Installed rom is global stable 10.0.5.0
What must I do to developer options unlock status show true(locked).
thanks...

cannot mount storage, please help
