My phone is LG Prada P940.
The problem is when I connect the phone to usb debug mode, status bar show slow charging, usb debug start completely.
But, when I try to root it in cmd, it sticks at daemon running. When I try "adb devices" command, it says "xxxxxxxxxxxxxxxxxxxxxxx offline".
Now I can't root my phone.
Anyone have had experience for this solution? Please help. Thanks in advance.
Just try the below command and post your findings..
adb kill-server
adb start-server
And make sure usb debugging is checked

Have you tried with another PC?? If not have a try..
Are you sure drivers are installed and that your pc recognizes it?

Thank you for all your help. I've tried all of those solutions: tried on the other computers, the phone could be recognized and I could even upgrade the firmware, and stuff. Unfortunately, couldn't be rooted because the devices offline issue.
Any other ways? Please!

Absolutely. The main issue is that I couldn't run any root methods to root the phone, because of the ADB devices offline.

Were all the computers you tested on running Windows? How about trying running ADB on a Linux PC and see if it works?
Another thing, maybe you can try installing this driver on Windows just in case it's a driver issue:

Thanks a lot. I wish it could work, but it did not.
By the way, my phone used to be rooted before. One day, I did something wrong with the 'bootloader' file in the system folder, then the phone could not restart. I had to do some things such as: downgrade, upgrade the firmware, and stuff. Everything seems ok then. Just the phone could not be rooted any longer.
Have any ideas? I will try whatever. Please!
I have same problem. plz help

How exactly do you enable ADB i was doing the whole root this morning and tryed the webtop mod and i was going to push the commands through adb but i couldnt get it to work so what exactly do i need to do to enable this
Settings, applications, development, usb debugging. That's it
Make sure you have drivers installed on your computer

or you need to get the required drivers, I found windows update installed most of them without issues but I installed the one from the rooting tutorial for safe measure.
I have the moto drivers installed from their website and I can see "Android ADB Interface" in my device manger but yet adb is not working for some reason.

Toggle debugging on then off.
I am in the same boat as you. A suggestion was posted in my thread in the Q&A section that PDANet solves the issue as it installs the drivers for you but it didn't work for me. Any dev's know a solution to this issue.

When you say that it should work, are you referring to the fact that we can run the exploit and unlock the phone even though it doesn't show in adb devices? I haven't been able to get mine to work that way. Thanks.
The pdanet didn't work either same error as previously stated. Mine doesn't even show up in fastboot devices. I am at a total loss here. I tried to override the drivers and it fails and states that the MTP USB Drivers are the most up to date and refuses to change or update it.

No, the exploit will not work if your phone does not show up in adb.
Also, this thread should be in Q&A, not in Development.

How can we get cwr whithout an unlocked bootloader or root. This isn't helpful unless we have cwr already on there which we don't as we don't have root because we don't have adb to push the exploit. I don't mean to be rude but I am getting aggravated with this ADB thing.

did you change your environment variable path set to your adb/fastboot location?
As for the drivers:

Hello,
I had similar issues with ADB not recognizing the DNA, I disabled HTC sync and closed out of the HTC SYNC in the task manager... You may or may not have tried this... Based on my experience this was what happened with me.. I also have windows 8 64bit. Hope this helps
:fingers-crossed:
I installed drivers listed on one of the forums here. then i installed htc sync. Then i had to download the sdk /with google drivers.
I would assume that when you have your command prompt open that you cd into the folder. platform-tools. that way the cmd can find adb?

If you set up adb right you don't have to CD into that folder.

You need to disable HTC Sync. Go in task manager and see if there is another ADB current running. That is what happened to me, HTC Sync was trying to push via ADB so when I tried to root it couldn't recognize my DNA.
a day after i rooted and flashed a rom on my l9, it just died, idk how. can't get into any kind of "mode". the strange thing is when i connect is via usb it tries to connect but a dialog box comes up in the bottom right saying "USB device not recognized" it makes the connect/disconnect sound over and over until i unplug it. Device manager doesn't show anything, it just keeps refreshing because the device is attempting to connect. I've tied different cables and different ports also, and no luck.
any help will be greatly appreciated, thanks

All drivers installed correctly and the phone is being picked up through mass storage and connects to computer fine.

Not sure it would matter since you're running commands from ADB but did you turn off fast boot in the power options? Also, I know there's a tool somewhere here on XDA where you can remove all of the android drivers and start fresh. I want to say it's called USBDeview. It was part of the WugFresh nexus 10 toolkit. I used the tool to get rid of all my samsung drivers and also HTC drivers so I could start fresh
Here's a link to the toolkit. Try using the driver installation guide there, it has the tool in it I used to get rid of all the android devices to start fresh.
http://forum.xda-developers.com/showthread.php?t=2015467
This is assuming your drivers are the problem which is what it sounds like
Edit: just use that toolkit for the USBDeview tool, not to unlock your device as it is for the nexus 10. Lol sorry had to just make sure

umm, did you enable developer options and enable usb debugging? if you type adb devices and nothing shows up, its not going to work. You should learn how to do it all manually anyways. It could save you in the future. Go to htc dev site and it walks you through it for windows and mac. VERY easy. You need to learn to use fastboot commands. Msg me if you can't get it done.

Right, and I guess I'm saying that it may be worthwhile to try cleaning out your drivers and then starting from scratch with HTC driver and android interface driver. When I cleaned out mine I had several duplicated. After removing them I was able to connect to my device just fine. I can't think of another reason why your device wouldn't connect

ive never had any problems with command ADB DEVICES showing the connected device until this phone. I CANT use htcdev because it makes me download some file called "fastboot-win.zip" and after extracting it wont opne and gives me error message of some missing file which is indeed not missing. And dont you need ADB when you get the unlock token anyway? never had this type of issue before.

You must enable usb debugging to use adb on htc. go, settings, about and click on build like 10 times until it says developer options, then go to settings/developer options and turn on debugging. adb will not work on stock rom unless you do this.
Do you have the fastboot application in addition to the ADB application in the directory from which you are running commands? You absolutely need fastboot to get your unlock token.
Also just to clarify, what exactly does it say when you try to run ADB commands? Simply "device not found?"

Reboot your computer, install HTC sync manager again, then plug in your phone and drivers should install properly. But of course uninstall or close sync manager before you start running commands again
newest adb? usb 2 port? I have a mac so its a little different, but i had to update my adb when kit kat came out.

Do you get the same result when you run 'adb devices' in command prompt? Also uncheck verify apps and unknown sources in security. And I just want to make absolute certain you have usb debugging enabled once more

ok so i ran the toolkit for the 3rd or 4th time and it rebooted in fastboot to obtain my token to unlock. but when i enter the token into htcdev website it keeps saying its wrong length. i checked over and over and its the right length and im copying what i see from the htc dev website instructions but three times i get wrong token length.
ok i got the code to work..now onto the next step.if i have problems ill be back here.
