I have tried everything I have read on here and I cant seem to flash recovery. I used pwnmymoto to gain root when I first received my moto x. When the camera update came I thought I unrooted and flashed back to stock becasue I was able to get the OTA. Yesterday I could not install the OTA 4.4 because it gave me a error sign. I tried to flash recovery using fastboot but everytime now matter what I do this shows up:
colins-air:Android Tools colinj22$ ./fastboot flash recovery recovery.img
(bootloader) Variable not supported!
target reported max download size of 805306368 bytes

OKAY [ 0.798s]
writing 'recovery'...
(bootloader) Preflash validation failed
FAILED (remote failure)
finished. total time: 1.848s
colins-air:Android Tools colinj22$
Can someone please help me. I am fairly new to fastboot and I am on a Mac and I have read everything in these threads and nothing seems to help. Can I erase everything and somehow start from scratch?
Thank you all!

try using a different fastboot besides the one you are using. also make sure you are trying to flash the right FW version. you can't downgrade FW so it needs to be the FW version that is currently on the device.
try the second link in the OP of this thread for a different fastboot
http://forum.xda-developers.com/showthread.php?t=2489249
Flashing recovery requires a unlocked boot loader, you're obviously on Verizon and unless you have a DE moto you can't flash recovery due to your boot loader being locked

EDIT 3: Okay, just flashed a new kernel and the WiFi is working now. Must have been the stock kernel for some reason.
So all problems solved now
EDIT 2: Succesfully flashed the ROM, but unable to connect to Wifi. When I press the on button, it switches on for a second and then switches off again. Any idea guys why?
I've been trying to flash the stock ROM, but can't because as soon as I begin with the first step i.e fastboot flash partition gpt.bin, the following error is displayed- fastboot preflash validation failed.
Now I've been reading up on the forums here and a some have said that this error occurs when someone tries to downgrade. But I'm on the latest build and I don't know why this is happening?
Just so everyone knows, I'm unlocked and rooted.
Please, I need help since the ROM I'm on, which by itself is stock, is pretty much not working.

You can ignore gpt.bin and motoboot.bin. They won't flash if the same or lower version. Not a problem. Just continue flashing the other files.

Okay, thanks man, I successfully flashed the ROM. But now I have another problem. I'm not able to switch on my Wifi. When press the on button, it switches on for a micro sec and then switches off. Any idea why?
Don't know. Maybe a reboot. After that I would wipe dalvic, cache and data?

I did better, a factory reset. Nada.
Would flashing a different kernel help?
Did you do a
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
This is a wififix for the kernel

Oh I didn't know that this was a wifi fix, but yes I did perform the above steps as well.
But anyhow, I flashed a new kernel and it did solve the problem.

Didn't you read anything of the previous posts?
If you've unlocked your bootloader, and getting these errors, you can safely ignore them. Just carry on flashing the other files.
Carried on
I did carried on with the fastboot steps but I get this "UTAG "flashfail" is configured as fastboot" and I'm still stuck in Bootloader.
How do I change the Kernel?
Oh yeah, I updated to Lollipop about 20 days ago, worked fine until a few days back and suddenly I get these strange errors. What could be the cause though?

i also have same poblem d415
me too...same problem D415 tmobile version
Does anyone with this problem have an lg d-415 and android with root? Because I think these commands in a terminal emulator or in an adb shell will fix fastboot:
Code:
su
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/laf
Or if that doesn't work try this >> https://forum.xda-developers.com/lg...ick-hard-bricked-l90-variants-t3173429/page24
I think this problem is caused by people not unlocking the bootloader.

PLEASE HELP. I'm getting the same error on my LG D415. They said on the other thread that this variant comes with the bootloader already unlocked but whenever i try to enter a command (e.g fastboot flash laf laf.img) or pretty much every command I enter (except fastboot getvar all and fastboot devices), I get the same message FAILED (remote: unknown command). My android is now stuck on the T-mobile logo whenever I try to power it up and I can't flash because download mode has been replaced with fastboot.

Hello all!
So recently I was playing around with my G4, and decided to see if i could boot into fastboot mode. Turned out I could: theandroidsoul.com/lg-g3-fastboot-mode-61660/, but it would remove download mode in the process. It was totally useless. I couldn't run any commands and so I decided to put download mode back. I rebooted my phone, a notification caught my eye, and I completely forgot to put it back.
Fast forward a couple days, and my phone starts to run at 2 miles per hour. So, I factory reset, losing root and recovery in the process. That still didn't fix it, and now the camera, all speakers, and microphone don't work. Now, I can't replace download mode without root, so I cant run the LG Flash Tool. I'm starting to lose my mind over this. Please help!
Can your phone boot to android at all? if yes, then this might help put TWRP back on the phone WITHOUT ROOT. http://forum.xda-developers.com/tmobile-g4/development/tool-one-click-twrp-root-t3172936 thank micromod for making it possible.

Factory reset should have kept twrp recovery on the phone. With phone off, hold vol down and power together, when you see lg logo just release power button the hold it down again stioll holding vol down. say yes to the next 2 screens and it should boot into recovery.
