If you have T-mobile H932 you do not have fastboot flash commands. You can boot into fastboot, but it's basically useless.

T-mobile H932 does not have fastboot flash commands so you can't use fastboot to install TWRP with fastboot. That's the whole reason @runningnak3d had to create a whole new method -- using a Linux boot flash drive while on 10d Nougat -- to get TWRP onto T-mobile H932. You know this if you rooted your T-mobile H932!
You will have to do that all over again if you really lost TWRP.
The T-mobile H932 is a standalone island unto itself and is the hardest V30 variant to install TWRP on and root. All the others use the WTF method.
This and another reason is why only T-Mobile customers should use T-Mobile H932.

Especially if you updated to Pie KDZ/TWRP-flashable zip, make sure you are using the latest Dev Patched LGUP from T-mobile H932 Pie KDZ thread. Any earlier dev patched LGUP will only work on Oreo or lower. Follow the installation instructions, be sure to UNinstall any prior versions.

Well, you can still use H932 fastboot to unlock bootloader. And no hoops required to do that. And that's just about the only good thing about H932 ?
sadly, it was a year ago. I've noticed that installing xposed is dangerous as flashing custom rom even using magisk module, it sometimes make your phone boot loop, or fail to boot at all. any emergency tools such as Recovery, Laf download mode, should be present on their phone (at least one)

So straight to it, when I am trying to flash twrp recovery img with adb I keep getting failed (remote:unknown command) .
Process I have done;
Turned on oem unlock and debugging in developer otions
Unlocked boot loader via adb with fastboot oem unlock
Rebooted and got corruption msg but thats due to bootloader unlock
Put twrp in adb folder
Rebooted into fastboot
attempted to flash twrp recovery img via fastboot flash recovery twrp.img
Then thats when I get my error as follows;
target reported max download size of 536870912 bytes
sending 'recovery' (19412 kb) ...
okay [0.443s]
writing 'recovery' ...
failed (remote: unkown command)
finished. total time: 0.469s
Did I miss a step? I was reading something about a "fake" bootloader unlock besides h850?? I did achieve root with a tot file and lg up that did have already twrp baked in, but I need to get a stock rom so I can go ahead and switch between root and non root, cause I use an application for work that doesn't like root
i know this is an old post but i'm having the same issue. is it not possible to flash recovery with latest firmware?
same
I am trying to flash twrp or any custom recovery image so that I could root my LGv10, I am running Android 6.0.
When I boot my phone into fastboot mode I dont get the fastboot options just the options to exit or restart. However I still can run commands through adb, I try running the command to flash the custom image and I keep getting this.
Code:
C:\adb>fastboot flash recovery recovery.img
target reported max download size of 536870912 bytes
sending 'recovery' (5158 KB)...
OKAY [ 0.160s]

FAILED (remote: unknown command)

If I try to start up in recovery mode I get an android with a red error triangle, preventing me from rooting. Is there anyway I can fix this? any help will be appreciated as I've looked already and cannot seem to find a fix to this problem.
Hi, which model of the V10 do you own?
Please note that bootloader unlock and installation of a custom recovery is only officially supported on the T-Mobile Version of the V10 and the European V10 with the model number H960A. On the H960A you need to unlock your bootloader first. Otherwise flasing recovery fails.

Thanks for the reply!
My LGv10 is the T-Mobile version, model number LG-H901. I'm running Marshmallow 6.0, My bootloader is unlocked I'm still getting the same problem.
Not sure what to try anymore
Same exact issue I have. Don't know what else to do.
I was getting that yesterday, though I found another method that seems to have worked, only issue with that one is that whenever I try I flash a ROM, it fails with error 7.
https://dottech.org/198032/how-to-root-lg-v10-t-mobile-h901-on-android-6-0-marshmallow/
This was the method I used, though I didn't do it properly since I couldn't figure out what to do with the kdz file. But I do have TWRP recovery installed to my phone now.
Hi all,
Today I tried to root my LG G5 H830 but with an older method for Marshmallow(in the video i was watching the version wasn't even specified so I was unaware and I believed that the version of the phone did not really matter). I proceeded to follow this man's instructions @: "How to Root T-Mobile LG G5!" by "Max Lee" on Youtube(as a new user i cannot post links ) I unlocked my bootloader, got drivers and followed his instructions up onto an error on LGUP. Basically the error's purpose was to tell me that Nougat is not supported. So I had no choice but to reboot my phone and go through the android initializing setup.
After realizing the error of my ways I then found this post here via Google Search: "Install TWRP Recovery and Root LG G5 on Android Nougat | DroidViews" to install TWRP. Now my bootloader is unlocked and I have no root. The only problem here is that whenever I go into developer options and try to toggle 'OEM unlock' on it won't let me. The OEM unlock setting is grey-ed out and I am unable to toggle it!! This is what I need help with! Although my bootloader is very much infact unlocked I think some error occurred to where now I cant toggle my OEM unlock thus I am unable to flash a TWRP recovery via fastboot!
If I reboot into my bootloader and run the command "fastboot flash recovery recovery.img" i get this:
Code:
target reported max download size of 536870912 bytes
sending 'recovery' (18668 KB)...
OKAY [ 0.419s]
writing 'recovery'...
FAILED (remote: unknown command)
finished. total time: 0.435s
I even ignored the error and tried to boot into recovery manually and i just get the stock recovery.
Please help me guys
What about locking the bootloader again and unlocking it after that with the newer video you used?

Did you try to run the terminal/cmd as an administrator/root?

I've been struggling to get TWRP on my V30 (H932) from T-Mobile. I have already unlocked Bootloader and have activated USB debugging. I open File Explorer on my PC and go to my ADB folder where i have placed the TWRP.img file. On the search bar i type CMD in order to open a command window. Then i type "adb reboot bootloader" and my phone goes into fastboot mode. I have tried typing "fastboot flash recovery" and also "fastboot flash recovery_ramdisk" followed by the name of the TWRP file. Unfortunately, this is where i've been getting stuck. i get the following message:
C:\adb>fastboot flash recovery_ramdisk TWRP-3.2.3-7.img
target reported max download size of 536870912 bytes
sending 'recovery_ramdisk' (30860 KB)...
FAILED (remote: unknown command)
finished. total time: 0.013s
I'm not sure what i'm doing wrong in these steps. I have also tried renaming the TWRP file to "TWRP.img" but i get the same message. I read somewhere that using the OEM cable that came with the phone sometimes helps. I no longer have that cable so i can't try that. I would very much appreciate any suggestions to this problem. Thank You!

You're trying to reinvent the wheel.
The U.S. T-Mobile H932 was the last V30 to be rooted (August 2018 vs May 2018 for all the others) because T-Mobile removed most of the fastboot flash commands.
@runningnak3d had to create a process to get TWRP onto T-Mobile H932 and root it.
See link above. It's CLEARLY labelled "Root H932". IF you happen to go to the WTF instructions thread (the way to root all the other V30), I also have a link pointing to the ROOT H932 thread for T-Mobile H932 users.
Did you not search this forum any?
Was not aware of this. I'm kinda new at this so I didn't think to search specifically for the T-Mobile version. Thank you for the link.:good: I appreciate it.
Hey all,
I actually recreated this on both my LS998->US998 phones. I can get it to boot into download mode, but my computer doesn't even recognize a USB connection. It's driving me nuts, because I'd like to possibly fix the fingerprint issue once and for all.
I tried flashing the laf.bin from the 20b zip and it fails in Fastboot.
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flash laf laf.img
target didn't report max-download-size

Help??
EDIT: I fixed this by flashing the 20B zip again in TWRP. Jett's magical BS definitely breaks download mode

Flashing US998 20e TWRP-FLASHABLE zip has fixed loss of Download mode for others with compatible North American variants.

Yeah I edited my post. I ended up flashing the 20B zip. Download mode was restored after that. After flashing the 30B kdz, I did not lose download mode. Only thing that made me lose download mode was Jett's magical backup, despite everyone telling me it was "impossible"
