The command you have used is not a flash, it is only a boot into the twrp recovery, twrp will work than,
but nothing is flashed and so after reboot ther is no twrp.
Shut down phone, connect it to your pc, put it on, when adp is detected enter : adb reboot bootloader
than flash/boot into twrp and reflash
Have you tried a fac reset/wipe?
For Hardware Reset:
turn off the device
press and hold the power and the vol- key
release power key when the lg logo is displayed (holding the vol - key)
immediately press power key (you should still press the Vol - button)
when in the factory reset menu folloe the onscreen instrucions to wipe it

i know i have the same problem . im blocked in dowload mode . i cant do nothing
This might sound stupid so don't shout at me but is there no way you can dirty flash the lollipop version also try using twrp version 2.8.6.1 because the latest version caused me problems , good luck...
i was updating the zenfone 551ml to marshmallow so manually downloaded the update file and put it in the root of phone. phone detected the file and said to install update. firstly it was installing but after few minutes fastboot mode displayed on phone by itself and phone struck in it only no other screen came.
now i followed this guidehttp://forum.xda-developers.com/zenfone2/general/guide-brick-soft-hard-bricked-zenfone-2-t3284256
and used XFSTK load Downloader v1.7 downloaded the three files and clicked download in xfstk.
it completed sucessfully.
now my phone booted up on its own and is working fine.
but not able to get into recovery mode as before power+ volume down does not work, if i go to fastboot mode using power+ volume up key and select recovery mode the phone reboots back to andriod os.
Also tried to flash using the Asus flash tool but the device is detected for a sec and then diappears under device manger as moorfiled device.
pls help me get back in recovery mode

Hi All
My fd update his phone to Android 9 yesterday(do it on the phone, not the computer)
When the phone is completed and restarted, it stuck in the screen logo razer and the message " download mode " in the upper part .
He tried to restart the phone, but the same problem kept happening
Then I tried to press the power button and volume "+" at the same time to enter recovery mode, but failed, it went into the download mode again..
I have tried the command " adb reboot recovery " and I have the message " error : no devices/ emulation found
Then i tried the command " fastboot reboot recovery ", it went into the download mode.
Then I tried to flash the factory images.
Sadly, he did not unlock the bootloader and did not enable USB debugging...
So i can't flash the factory images....
When I execute the flash_all script...
It show FAILED ( remote: Flashing is not allowed in Lock State
)
Is there any other way to rescue it?
