Needed: Fastboot command to reboot into recovery! - Android Q&A, Help & Troubleshooting

Hi,
My LG5 850 is rooted and wiped, after testing another custom ROM. However, this time I can't reboot into recovery using the Vol-dwn/Power key-combination. Always ending-up in fastboot
Is there a command to take it from there?
Thanks a lot!

Bash:
fastboot reboot recovery
Should generally do the trick.

Unfortunately not:
LG5# fastboot reboot recovery
fastboot: usage: unknown reboot target recovery
Also tried:
LG5# fastboot flash recovery twrp-3.4.0-0-h850.img
target reported max download size of 536870912 bytes
sending 'recovery' (21124 KB)...
OKAY [ 0.681s]
writing 'recovery'...
OKAY [ 0.226s]
finished. total time: 0.907s
LG5# fastboot reboot twrp-3.4.0-0-h850.img
fastboot: usage: unknown reboot target twrp-3.4.0-0-h850.img

[Q] [Solved] [5.0.2/LTE] Cannot boot into recovery mode

Hello guys,
I've flashed TWRP for Nexus 9 2.8.6:
Code:
#adb devices
List of devices attached
HT4C3WV01363 device
#adb reboot bootloader
#fastboot devices
HT4C3WV01363 fastboot
#fastboot flash recovery twrp-2.8.6.0-flounder.img
target reported max download size of 518205818 bytes
sending 'recovery' (13208 KB)...
OKAY [ 0.744s]
writing 'recovery'...
(bootloader) Device State : Unlocked
OKAY [ 0.867s]
finished. total time: 1.612s
There's no way to continue into recovery without rebooting:
Code:
#fastboot reboot
rebooting...
finished. total time: 0.099s
#adb reboot recovery
... leads to a fallen Android! (see attached screenshot)
Any suggestion?
Fastboot flash TWRP recovery again.
After doing above, don't touch your PC again. Pick up your device and use volume button to navigate to hboot, then navigate to recovery and use power button to select.
Done.
Yes, thanks!

TWRP for Zenfone 3 Zoom

Now that we have our own forum I figure I might as well put this here (taken from guide here).
1. Unlock the boot loader with the instructions / app from Asus
2. Download TWRP. Specifically twrp-3.1.0-0-Z01H-20170408.img ** [edit: also rename to twrp.img once downloaded]
4. Reboot to fastboot by rebooting the phone, and pressing the down arrow during the unlock screen.
5. Flash the recovery image `fastboot flash recovery twrp.img`
6. I had to power cycle the phone completely to get TWRP running.

Hi there,
was wondering did you put the recovery file into the installation folder of ADB
yes, thats not the the problem, i manage to root my phone but cant to write TWRP, i get the same msg tried many toolkits and results is the same...
Since Oreo: Partition names have changed and "recovery" changed to "recovery_ramdisk".
Try:
fastboot flash recovery_ramdisk twrp.img

some weeks ago i read on forum that miui10.0.3 or 4 has some fastboot errors,
for example if you have flashed miui10.0.3 or 10.0.4 and then try to write recovery it will give error in fastboot
i would suggest flash miui10.0.1 or earlier via miuiflasher fastboot rom and then try!

I press power Volume Up but the phone boot in Fastboot
you have flashed a bad boot image. if you are on a11 stock i dont think twrp work 100% safe. los recovery is recommended and work without problems
