Im starting this new thread because I was not able to find a solution for my problem for about 2 weeks now.
Issue : Unable to install recovery. Im trying to install recovery by following this thread : http://forum.xda-developers.com/showthread.php?t=2221102 - in the 3rd step when i flash the recovery i get this error "command write failed - unknown error"
- tried almost all the different types of steps available in xda and also outside xda.
My Environment:
Win8 Pro 32bit
LG optimus L9 flashed and rooted by lelus method - Current ROM - P76020c
Installed all LG drivers - PC suite is installed
Have SDK manager installed
Device is recognized when I run the "adb devices" command keeping phone switched on.
Device is recognized when I run the "fastboot devices" command when phone is in fastboot mode.
So I guess this is not a driver issue.
Im also attaching screenshots of the error and the commands that I have ran ....
SOOOOOOOOOOOO ... whats the prob here .... ... anyone faced this same prob ???? HELPPPP

As always, use at your own risk.
Upload recovery image to sdcard and change the file name to recovery.img if that helps
flash via adb from your computer
Code:
adb shell su -c busybox dd if=/sdcard/external_sd/recovery.img of=/dev/block/mmcblk0p4
or terminal emulator straight from the phone
Code:
su
busybox dd if=/sdcard/external_sd/recovery.img of=/dev/block/mmcblk0p4

May be your file is corrupt. Just give it a try.
Download latest version of CWM Touch and Non-touch version from http://www.clockworkmod.com/rommanager and try again.

Lelus is explaining you in details and he is expert here. I am just confirming that if you have tried the basic things or not. By the way, your fastboot drivers seem working as device responds to "fastboot devices" command properly.
The fastboot screen should show the phone is unlocked or not, exactly like this....does it show like this screenshot?
SW Upgrade mode also should show unlocked like this screnshot.
If not, you may not be yet Unlocked and fastboot will not work.

I din know where exactly to run those commands, so asked detailed steps
And the my bootloader is unlocked, I get the fastboot boot mode when I run the adb reboot command to unlock bootloader, yday when I flashed my phone with v20c, I gt the second screenshot as yu mentioned, also i tried running that *# command from inside the phone and it showed bootloader status- unlock.
So I hope it is unlocked! !!

The device never gets recognized so easily on "adb" whereas in fastboot u would not have any issues.....
since u r going to flash the kernel try "fastboot devices" u ll be able to see ur device
The adb issue will be solved by restarting the PC or by trying to re-install the HTC drivers

I tried fastboot devices and enter but it's just blank nothing
I tried restart PC didn't help, I tried to restart the phone too, and reinstalling drivers nothing.
Even WinDroid HTC One X+ Toolkit won't recognized him when he is in fastboot, but when he is in windows he said Online on status. I really have no idea where did I go wrong I usually always get him into fastboot flash normal.

I always had the device shown as BLANK on "adb" when using windows
whereas on fastboot I never had that issue.....
can u try this
In windows install this MInimal ADB and Fastboot give a try on"fastboot devices" using this
if not working re install the drivers and try the MInimal ADB and Fastboot again
I am suggesting this because it had worked flawlessly for me with proper drivers and MInimal ADB and Fastboot.......
I never had to install drivers I just installed some adb universal drivers from WinDroid HTC One X+ Toolkit 3.0 it always worked without installing any other drivers, but all of the sudden it's not. I tried now using that MInimal ADB still blank, I will try now to reinstall or uninstall completely that adb universal drivers, and try again.

Installation won't start on this one that you gave me. I run it but nothing happends.
P.S
I download AdbDriverInstaller he said that I already have installed adb drivers, don't know how when I uninstall it all.
EDIT:
I manage to get device ID on adb devices in windows, but when I enter bootloader in fastboot he can't recognized him on command "fastboot devices" he said "device not found", and I can't flash kernel becouse he needs to be in fastboot.

I did that too now, and in windows I get adb devices he show me number of my device, my friend told me now that I can flash kernel when I am in OS that I don't have to be in fastboot he will enter fastboot on his own, and I try that too, and as I told he manage to find device via adb, but when he enter bootloader in fastboot he is waiting for device in kernel cmd windows he can't find him.
Make sure your using a USB port that connects directly to your mobo. adb/fastboot is dodgy with USB hubs. Try a port at the back of your PC.

Adb is showing list of devices attached..what is the solution for this..if any one knows how to solve this problem can u help me??

On the device I'm using, this was under "Default USB Configuration" - advice from others appears to be that selecting PTP is the way to go.
For me, it works =).
Hope that might help out.

I am not familiar with Linux but on Windows waiting for device comes up when the driver for that phone is installed. May be you can look into it for a solution.
Install the drivers and then give it a try.

You need to install adb fastboot these are the instructions you need to type in the terminal you just opened. Type one line at a time and press enter after each. Allow Ubuntu to do it's stuff.
sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install android-tools-adb android-tools-fastboot
after you reboot to the bootloader you use fastboot commands ,not adb

Sorry, I'm messing up what I'm trying to say. I have adb and fastboot installed, running on ubuntu 16.04. I plug my phone in, open Terminal, and run adb devies. My device pops up, it's there. So I run adb reboot bootloader, my phone goes on the white screen with the android fellow, and all is good. Now, I i try adb devices again, nothing. I put in lsusb (lists all usb devices connected to computer), and nothing. So, naturally, when i try fastboot oem unlock and my code, I'm stuck on <waiting for device>

adb does not work in the bootloader
After reboot bootloader it's fastboot devices
If you get no response try a different usb port
Or different usb cord

My PC doesn't detect my phone when I use Fastboot Devices when my phone is on Fastboot mode. I get a blank space in return. Can anyone help me with this? ADB works fine, it's only Fastboot. Is there a Fastboot driver that I might be missing?
Thank you.
Edit: I'm trying to unlock the bootloader of my phone.
Me too !
Drivers are here: https://developer.android.com/studio/run/win-usb
These are the ones I use for ADB/Fastboot.
May I ask if anybody solved this already?
Having the same issue, tried various drivers, but fastboot won't find my phone
Help is highly apperciated!
Clock
If you using windows 10 have you disable the drivers signature verification.. And search on here (XDA) for Min ADB & Fastboot tools, easier than using SDK tools unless you modding apks ect..
Okay, I got this working.
When in fastboot mode, you have to go to the device manager, update driver, and manually choose the google fastboot driver. Then the ! is gone and it works.

It seems the driver is not installed properly.
How can I update the driver so that windows can recognize the phone on fastboot mode?
I have tried drivers from following 2 links,
https://mega.nz/#!XqAR3QbQ!BMg_NMelPhJPXRTA8y96yGJVnCg4IUgHDVzQmco83cI
and
https://androidfilehost.com/?fid=962187416754460440
I have also tried all 3 options
Android ADB Interface
Android Bootloader Interface
Android Composite ADB Interface
But none of these worked.
Can anyone tell me how do you make it work?
thanks!

I think where a lot of people get hung up is they type "adb devices" after going into bootloader. They should be typing "fastboot devices".
my problem solved by laptop with unbuntu
you are right. update adb and fastboot worked.
