Hi all,
I have an LG G5 H850. I'm trying to install TWRP using ADB. I've had it previously and it worked fine. I'm pretty sure the bootloader is unlocked. Anyway, when I do "fastboot flash recovery twrp-3.1.1.1-0-h850.img" I get the following output:
target reported max download size of 536870912 bytes
sending 'recovery' (19076 KB)...
OKAY [ 0.431s]
writing 'recovery'...
OKAY [ 0.345s]
finished. total time: 0.781s
To me, that looks as though thats worked fine. Now when I try fastboot boot twrp-3.1.1.1-0-h850.img I get the following:
downloading 'boot.img'...
OKAY [ 0.432s]
booting...
FAILED (remote: unknown command)
finished. total time: 0.456s
Has anyone got any ideas on this?
Same here
I am having the same problem, please help
Had this issue a while back. I resorted to doing complete flash with LGUP to the latest version and then it worked. I had been messing around with various ROMS on different android versions.

Don't happen to know where I could get a rom that it would work with do you?
Managed to solve this. Flashed the TWRP image using fastboot flash recovery <img> via adb. Then I unplugged from USB, and got into recovery mode by doing power + volume down buttons and quickly release and repress ont he LG logo. Answered yes to both questions and got into TWRP.

That is the required way of doing it. You have to boot into recovery after flashing the recovery or it gets reset.
Hi,
Having a similar problem since trying to update my ROM ... and the Magisk install failed. Now I can only get to fastboot, can't get to recovery. And, tried this,
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flash recovery twrp-3.1.1-0-h830.img
target reported max download size of 536870912 bytes
sending 'recovery' (18644 KB)...
OKAY [ 0.439s]
writing 'recovery'...
FAILED (remote: unknown command)
finished. total time: 0.461s
Help!?! ... and thanks!

I followed @neo.ank's all-in-one guide and am having trouble flashing a custom recovery (twrp-2.7.1.0-condor.img). My bootloader is unlocked and fastboot flash recovery recovery.img works without problems:
Code:
C:\Folder>fastboot flash recovery recovery.img
target reported max download size of 268435456 bytes
sending 'recovery' (7300 KB)...
OKAY [ 0.235s]
writing 'recovery'...
OKAY [ 0.232s]
finished. total time: 0.471s
I then use my volume up and down buttons to select "Recovery mode," which returns me to the bootloader (the logs say "Boot up failed"). So I boot up into Android and adb reboot recovery, which works.
Now I see the "dead robot" with "No command." Huh, oh well, pressing power and volume up shows the "Android system recovery." A step ahead, but where is TWRP?
I think the guide I followed may be outdated. Has anyone had success using it to flash recovery on the 2015 Moto E?
TL;DR: Successfully flashed TWRP recovery, but it seemingly disappeared when trying to boot into it.
Fixed. I used the wrong recovery.img. Using the surnia recovery instead of condor works: http://forum.xda-developers.com/devdb/project/dl/?id=11449
Hello. Today i tried to flash the phone to the stock ROM twice but it didnt work probably cause unlocked bootloader and custom recovery (TWRP).
So i brick the phone and now i cant access the rom or the recovery. All i can do is access the fastboot mode. I tried to install the new recovery through fastboot but it doesnt work.
I tried the twrp 3.0.2.0 and 3.0.1.0 for yuga.
Code:
C:\Users\Kubo\Downloads\platform-tools>fastboot flash recovery recovery.img
target didn't report max-download-size

Tried various of commands that i found on google and this forum but nothing worked. I unlocked the bootloader before when i was installing various of custom roms. Could somehow stock rom affect the bootloader when i was flashing through flashtool ? I tried to only boot the recovery from the img, the command worked but the recovery did not boot.

If you already have TWRP before just use the app.
If its the first time you flash twrp using the Recowvery method, make sure you have a copy of the recovery.img on your internal memory. :good:

Well this is a v521 forum. So if you have a v521, then trying to flash twrp for the v500 would be your first mistake.
Can you kdz back to stock?
I have the 521 I trying to Restoring kdz lg tool not seeing my device detected

Yeah you tried to flash twrp for the v500 which could probably mean a hard brick.
Read the last couple pages of this thread to see if it will work for you. Good luck. https://forum.xda-developers.com/g-...-v521-guide-to-update-v521-lg-t3533338/page28

Its listed as an Android Bootloader Interface if that helps...
Then maybe try using fastboot instead of adb you can install stuff from that.
