had a similar problem. install PdaNet app to your computer and it'll install correct adb drivers.

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??
@Vinay23
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.

Hello, everyone
I rooted my phone 2 weeks ago and 2 days ago I got an update notification which I did and then something occurred and the phone started to reboot itself.
I tried to recover from the backup that I did when I rooted the phone and now there is a new problem. When starts, a message "com.android.phone has stopped working" pops up and I can't use the phone.
I tried starting on Recovery Mode multiple times with no results, the phone just starts normally. I also tried to connect the phone to the PC (Running linux) but the command 'adb devices' shows nothing.
Any help is appreciated.
Thanks!
P.D: Srry for my bad English
Enable usb debugging on developer options and plug the phone to your pc and run the comand "adb reboot recovery" and it should reboot to recovery
Sorry for my english

Hi!
Developer Options were already enabled. But the the computer doesn't recognize the phone. When running 'adb reboot recovery' it says "error: no devices found" (on windows) and error: device'(null)' not found (on linux)

On windows, you have installed the drivers??? And if you want view the devices that are plugged run these "adb devices" if the problem continues, try with an different pc or port usb
You can't boot into recovery? but why?
When you select "Recovery" option in fastboot mode what does it shows?
Its kernel error I guess....vest option would be to flash recovery using flashify or ad again

I am trying to root my J7 NEO but i cannot boot into download mode.
I have tried the conventional methods such home+vol d+power) and adb commands.
Nothing will work.
It is factory unlocked .
I can boot into recovery and tried reboot to bootloader option and that does not work
Can anyone help?
Hi , to use adb command enable USB Debugging to do that go to settings /about phone /Software information and click 7-8 time on Build number , now go back and click on Developler Option and enable usb debugging . Now connect your phone wait for adb driver to be installed, once is installed open adb command line type adb devices to see if your device is recognized next write adb reboot download . Good luck
