I've used ADB no problem in the past but now when trying to connect my phone (exalt) it says Error
Unable to claim interface. Any idea how to fix that?

Try running

adb kill-server

Apps4Flip-Admin I'm just a begginner how do I do that?

@klugs613 open Windows Powershell and type in adb kill-server, then hit enter

anonymousflipphone I got back this error
adb : The term 'adb' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the
spelling of the name, or if a path was included, verify that the path is correct and try again.

mg5077 If youre using powershell you have to start with ./adb (and make sure youre in the adb folder)

mg5077 What are you trying to do? Erase? add?
I can post a screenshot or a link of what the adb should look like. First in what context are you running the ADB she'll commands?

can someone help me, when i command adb kill-server this is what comes up,"cannot connect to daemon at tcp:5037: cannot connect to 127.0.0.1:5037: No connection could be made because the target machine actively refused it. (10061)"

chesky Did it ever connect that your looking to kill the server?

Or click Ctrl Alt Del and find the Cdm command and click end task.

how do i know?

chesky It would say device connected successfully or show connected. Take a look here on what my screen displayed after connecting successfully.

While using the abdweb site is much easier.
But if you want to play around feel free to use the abd command prompts

i got access denied on webadb, what do ido?

chesky Did you allow usb debugging? Using a good wire to connect to the computer?

chesky Connected the phone on the webabd ?

i allowed usb debugging, when i press connect it denies it.

chesky You have filter on your device?

no, i just took off the browser application.

chesky So you have no other CDM commands running in the background?
If you do click cntrl alt & Del together to pull up Task manager, and find the open cdm tab and click end task.
or what i would try is restarting your computer, That has helped for me many times.

Open back up the web page for webabd and reconnect your device with a good thick wire, anything of quality.
Allow USB debugging and click connect to pair your device, it should connect successfully.

Myi its enough to sign out and sign in again you don't have to restart

mg5077 I wish that worked,
I tried signing in and back out on multiple times and the computer wouldn't reconnect. A simple restart of my laptop did the trick.
What ever works for you I guess.
Just sharing my experience.

IM trying to use webADB with lg exalt but it comes up acces deneid error, can anyone help?

nothing worked its still showing acces deneid.

is there any other way to start voice acces, not with webadb?

@chesky @moshack Try unplugging the phone, then replugging the phone. A dialog should come up asking you to authorize the connection, make sure to click yes.

If none of the above work, try opening up a command prompt and running adb kill-server.

If that doesn't work just reboot

I'm using Kyocera cadence I need urgent an adb command to change the usb mode to "software update"
(see my thread here for more info on my problem)
I cannot do it in the device menu due to a device restriction,
does any body know such an adb command?

chesky usb set to photo trensfer?

Myi Thick does not mean good quality. Go for a name brand like anker, but I don't really think that that's the issues here.

aza chesky I hade the sane problem, changing usb mode solved it.
