Its either showing offline or unauthorized ive got sdk and java downloaded

On my Verizon model, when you plug in your usb cable, it will ask you how you want to connect (media sync, etc). You have to choose "Internet Connection" and the Ethernet, then adb will find it. The first time you connect with adb, you also have to accept an RSA certificate on your phone. Hope that helps

If it's showing offline and you have the correct pc connection selected, try disabling usb debugging then re-enabling it. Type adb devices in a command prompt and the RSA security should popup on the phone. That's what I had to do.

How do you get that RSA popup? or is there a way to add another? I haven't seen this at all.

I had this happen and it was I had the wrong lg drivers loaded. I googled Verizon LG G2 drivers and uninstalled the old ones and installed the new ones. That fixed the problem. Sorry I don't have the link handy.

I have a D802 and mine showed the same thing even when I have it set to media link but I went ahead with the root process with no issues and now have root. Before I switched it to media link it would just say disable in the comand prompt.

It's probably an sdk issue. Make sure you have sdk 16 and 17 fully downloaded. It's a security issue built in to 4.2 and I had this issue.

having trouble with usb drivers

so i am new to android and i decided " hey why don't i try to root my nexus" so i tried and i cant get any father that checking if the computer can see my device which it cant for some reason. so i went online i figured out that i don't have the usb driver for android. so after that i tried to down load then and i even installed them and restarted my computer and it still wont work. so if any one can help me with my problem it would be greatly appreciated.
On Home Screen, press menu>settings>applications>development and make sure USB debugging is checked.
What OS you running?
Specs would help, where did you get your drivers? What other software have you tried?
i turned on the debugging and it still hasnt worked
i am running xp. i downloaded the android sdk from here
developer.android.com
i just want to put the modaco desire rom on my phone that my onl reason for wanting to root. i really like the sense ui
I am having a similar problem, so i might as well use this thread instead of creating a new one.
I have a dual boot computer, win7 and fedora, both have SDK. I unlocked my nexus one with windows, as i noticed the commands were considerably easier, or at least they don't work when i plug the linux ones into fedora.
Last night i was going to push the undervolt kernel so i plugged my n1 while in win7, It instantly came up complaining about drivers, which i had already installed and had previously worked, i went to re-install them, and windows says they are up to date, but still no luck recognising the device (Debugging mode is definately on)
So i switched to fedora, no driver pop ups obviously, but when i try to push the kernel through, it does not recognise the device.
In the bootloader it says "fastboot usb" while plugged in.
I can't pinpoint when it stopped working, but the last time i used fastboot was to put the RA recovery, since then i flashed CM 5.0.2, CM 5.0.3.1, the desire rom, and used a nandroid restore to get back to 5.0.3.1
Anyone got any ideas? Without fastboot i am pretty much restricted to flashing .zip files from the recovery.
yeah i cant even unlock mine its so frustrating
Me either. I'm coming from windows and flashed the heck out of that. The instructions seem super easy, but the darn thing wont recognize phone to root... and there is no real good instructions on the driver part. Yes USB debug is enabled... sucks cause I want that desire rom, if 10.1 is working that is...

not everyone is a dev
Ok, I have my Nexus One set up so I can use with via Windows 7 (desktop) or Ubuntu (Laptop).
The Linux part is a bit more involved, but since everyone is running Windows (unless I missed something), I will work there.
First of all, your phone needs to be in Dev mode (which was covered earlier).
With the phone UNPLUGGED from the PC, uninstall any previous SDK installs you have and be sure to remove the directory.
Then, install the SDK found here: SDK
Install this SDK and let it complete the install, which will include downloading for a bit. You need to do this since the SDK package above does NOT include the right drivers!!!
Once this has been completed, plug your phone into the computer via USB. Your computer will find a new device, however, it cannot locate the drivers for it. Browse and point the installer to:
DRIVE:\PATH_TO_android-sdk-windows\usb_driver
Don't go any further than this!!
Now, let it do it's thing and you should have a new device in the device manager called:
Android Phone
...|_Android Composite ADB Interface
Now, go to the command prompt and change to the following directory:
DRIVE:\PATH_TO_android-sdk-windows\tools
There, you will find adb.exe
Type:
adb devices
and you should see:
List of devices attached
HT019P801614 device
If not, something got screwed up and would need to dig further to help ya.
Ok ill give this a try once get home from school
nexus one root.
Ok assuming that you have the android sdk installed correctly, try rooting your phone via the superboot method. The first link below has a full detailed guide for rooting the nexus one and I believe has all of the device drivers for those who have not been able to get them running well. If you still have trouble getting the drivers working checkout the second link. Anyone who is relatively new to working with the sdk and is not familiar with working the commands check out the third link. Read the entire thread! it is very helpful.

3) http://forum.xda-developers.com/showthread.php?t=619153
If you have any questions PM me on xda. I'll try and help in anyway, it took my like two days to actually root my nexus, I wasnt familiar with using ADB and Fastboot to root.
One thing I know I was having problems with since I came from the G1 was that the new SDK has to actually be installed via an .exe now. I was used to it all being in a zip so I kept trying to load up what I thought were the right USB drivers, but they were actually the 1.6 drivers I already had. So make sure to run the .exe that comes with the SDK.
ok so while i was downloading the sdk a notification came up that said that it could not rename the directory. is this bad?
i am having an issue with installing the right driver as well. my computer keeps installing the nexus one as a "mass storage device". i have uninstalled and reinstalled a few times but no luck. i have the phone set to debug mode, using XP btw. any help would be appreciated.

Lost ability to ADB - help needed

Here is a mystery that never happened to me before.
Got the phone yesterday, rooted it and restored my apps.
Today i noticed that when i plug the phone in (USB debugging enabled, drivers from motoroal installed), i can see the device under "Android ADB composite device" but when i use "adb devices" from the command prompt, i get:
List of devices attached
TA20706TVK offline
I am not able to do anything else as the device is offline ?!?
I tried on 3 different PC's running Windows 7, windows 2003 server, windows XP, all with the same results.
Anyone has any idea what's going on?
My Evo gave me grief for a solid hour when I first got it. Followed the walkthrough here and one of the contingency plans worked like a charm.
http://theunlockr.com/2009/10/06/how-to-set-up-adb-usb-drivers-for-android-devices/
Thanks, but it is not a driver problem as the drivers are installed correctly and ADB can see the phone connected.
I tried on 3 different PC's, replaced US cables. everything failed.
I think something is up with my unit which will be going back tomorrow.

So it worked fine before you rooted it?
Yes, SuperOneClick is using ADB to push the root files, so i assume ADB worked then.
I am also getting constant device reboots (random) so i think there is a hardware problem. i'll take it back tomorrow.
I had drivers installed, but the set of drivers PDAnet ended up installing for me fixed the issue. Till I get my paycheck, I won't be able to play with it

I have the same issue! I had rooted my device and everything was fine. I wanted to try DG's new deodexed rom, but I can't get ADB to work anymore. My device is found but it is always offline. I have tried multiple computers and usb cables with no luck. Is there any solution? What could have happened, is ther something wrong with my Atrix? It was working fine before, but now I can't get adb to get my device "online". I uninstalled the drivers and reinstalled the many times without any luck. Please HELP!
I am now on my 4th phone - so will be waiting for things to simmer down before I go back to modding again, but the other 3 have all had the same issue after using the superoneclick to root.
Once root is done all ADB access goes away. Something is amiss.
edit: More specifically my 4th atrix.

I am not sure. ADB died on my 1st device after rooting it BUT the device was also having other issues of random rebooting at least 4-10 times a day. So i replaced it and the 2nd device does not have any issue and i rooted it the same way.
I have ADB working and it does not have the random reboot the issue.
The only thing i did not do on the 2nd device is used SuperOneClick to enable none market apps like i did with the 1st device.
I am not sure if that's what made the difference. I did enable sideloading by manually editing the settings.db file.

I havent had any hardware problems at all with my atrix. I did enable sideloading via the superoneclick though. The loss of adb pisses me off. I did hard reset my device once, but i did that because adb wasnt working and i thought a hard reset would fix it. I hope there is a fix soon though, i hate having to exchange my atrix for another one. Maybe something happened to a system file that enables adb?

I tried restoring my device to factory default several times. It did not solve the ADB problem and not my random reboot problem (even with zero 3rd party apps installed).
I tried installing ADBWireless from the market - no go.
I googled and found a command to run via local terminal to force ADB to stay up - no go.
I finally came to a conclusion that a) I have bad hardware because my device was rebooting b) i can't fix the ADB problem without a full SBF file which we don't have.
Went to at&t, got it replaced. no more reboots. rooted with superoneclick and did not do the sideload fix from that app.
Then i manually edited the settings.db file to allow sideloading and been running fine ever since.
Clubtech,
Thanks for the file! It works for me!

[Q] Device Offline: Brand New Nexus 4, 4.2.2

So, got a replacement Nexus 4 today, and it's been updated to 4.2.2 and for some reason, it comes up as offline on ADB no matter what I do.
However, the funny thing is, my other Nexus 4, the one I was getting the replacement for, connects to ADB wonderfully. Shows up as a device, no problem. It's on 4.2.1.
Question 1: How can I manage to get the gosh darn thing to be recognized as online. I've tried two different cables, both of which connect with the 4.2.1 nexus but not the 4.2.2.
Question 2: Can I install a custom recovery without ADB?
EDIT: Consider this solved... it seems I had a bit much to drink... little did I know I don't need ADB... just fastboot.
Oh well All is well.

Is the device recognized by Windows? Checking under Computer>Properties>Device Manager does the phone show up correctly?
Use the search in the future please. Just update ADB. With 4.2.2 the phone will pop up to ask you if you want to authorize your computer to access the phone, this "feature" requires the updated ADB, no change to fastboot, so you'll be fine getting the recovery on there, but ffr with ADB.

If you're trying to unlock and root your nexus, you can follow the steps on this forum http://forum.xda-developers.com/show....php?t=2147413 There's another way to unlock and root your device (via adb) since Wugfresh's NRT doesn't support 4.2.2. Just make sure you use the correct .img file for your specific device.
You can also update any old SDK files by opening the SDK Manager on your pc.

I did use the search feature and I will have you know that the FIRST THING I DID was download and update the absolute most recent ADB so thank you, but the degrading "learn to search" comment was not applicable.
Anyhow, this whole conversation is fairly irrelevant since I got what I needed to do, done.
Thanks for the help everyone.

Hey
Guys had the same problem and it was really simple to solve.
When you start adb and type adb devices and your device comes offline.
Go to settings>developer options - unchecked USB debugging and check it again, right after your computer will recognize your phone and in the phone will appear a box with your computer's Mac address asking you to allow connection.

Have you downloaded the updated version of adb from post #8? And make sure you use that rather than whichever you were using? That was all I needed to do to get my offline Nexus 4 online again...

In that case, I don't think you get the "offline" status from adb - I think it wouldn't appear at all?
It appears that the Linux SDK isn't fully updated (as of today, newest build is 0219). My adb version is 1.0.29, and from a bit of research it seems that that version cannot ask your device for the OK it needs in 4.2.2. I hope I'm wrong though...
EDIT: When I had basically given up, I re-checked one last time, and there it was on my screen; the OK. Unfortunately, I have no idea what permitted this. Let the building start. Good luck to all of you!

I feel your pain as I too am having the same problem. I am posting on here so I can easily follow your post. I will tell you also that I think it has something to do with 4.2.2 but not positive at this point. I have rooted a Nexus One, HTC Dream, SGH679, so I do have some experience with this. I have changed ports, cables, started and stopped the service, rebooted the tablet, toggled the debugging just keep getting the offline. When I plug my phone in and use it, it sees it and it works fine, then when I plug the tablet back in it go back to offline. I even removed all the drivers on the computer just so it would get confused with the phone driver and still no luck. I think the driver is fine tho because it says it is in device manager, and I can transfer files back and forth from my tablet to my computer. Don't loose heart tho I think the answer is out there and I will keep working on it, and checking back to see if anyone else has had success.

So I was going to do it the old fasion way by following this guide
http://forum.xda-developers.com/showthread.php?t=2150661
I didn't quite get step four because the nexus 7 doesn't have an SDcard, but I copied the zip to the root of the device.
When I did step 7 the device did not go to Fastboot, it didn't go anywhere other than a black screen. I think I have a faulty unit, or the holding of the volume buttons with the power is really not the way to get to fastboot, either way I am looking at a brick right now. Any thoughts will be welcome. I messed around with it for 10 min now and got the device to re-boot. Not sure if I should try the fast boot option again.
Are you on Windows 8 by any chance?
Because I couldn't get it to work on Windows 8 and had to use Windows 7.

FWIW, here is my experience:
PC: Win7 Pro x64 SP1 - SDK platform-tools 16.0.1 - SDK Tools 21.1 - ADB v 1.0.31
N7: JDQ39 Stock *
( *OK, i diddled default.prop in my boot image to set "ro.secure =0". I don't know if that could make a difference or not )
The Nexus 7 asks for confirmation of inbound adb sessions for every new adb server invocation on the client PC.
When it does ask for credentials, you have to get to the on-screen display pretty quickly - a couple of seconds at most. If you don't the device will be reported as "offline" by the first invocation of
adb devices
If you accept the connection, the next time you run "adb devices", the status is back to normal (reports "device" instead of "offline").
You can test this out yourself - just iterate in a loop these three commands:
adb devices
adb devices
adb kill-server
Nothing that can't be understood by someone who knows what is going on; but I suppose that all the toolkits are running adb underneath the hood, so it is certainly possible to get tripped up when using a toolkit if you aren't Jhonny-on-the-Spot when that dialog pops up on the tablet.
Also, for the adventuresome:
I note that the new stock JDQ39 (4.2.2) ramdisk has a new line in the default.prop that was not in JOP40D (4.2.1) :
Code:
ro.adb.secure=1
I suppose that could be toggled off if you have a favorite kernel/ramdisk setup and you don't want to be bothered by this stuff. But it does mean unpacking/repacking your boot images.
cheers
I'm having the same problem. Never recognizes an ADB device. When it does it shows my serial number followed by "offline."
Any ideas? I'm ready to return this thing.

Out of curiousity what driver are you using and how are you installing it?
Also where is your device coming up in the device manager?
I've tried so many things that I think I'm getting off track. Sadly my motorola phones were much easier to root.
how come you cant?

How come you can't download and install from the SDK manager?
That's how my problem got fixed.

The sad thing is I have no idea what finally got it to work. Maybe just an extra reboot I had forgotten at some point. I do know however that I had to add a few extra lines (hardware ID) to the .inf file in the usb driver. Not sure which did the trick. I also used a combo of the toolkit to unlock and the manual method to root. Also I am unable to boot my device into the bootloader/fastboot via windows and rather have to manually (physically) shut down the device and enter the bootloader via the physical buttons. Probably an issue with the windows drivers again, but at least I have full functionality once in fastboot.
Only thing is now I can't get access to the storage via windows. And there's no way in hell I want to change the ADB drivers without knowing which finally worked for me. I'm thinking though that this is an entirely different device in device manager (I'm obviously not that knowledgeable).
Also I'm kinda annoyed by the unlocked padlock symbol on startup. I suppose that should be a welcome sign of achievement after spending all day trying to unlock/root, especially for such an unlearned person as myself.
did you clear this issue?

cause I'm a noob, I cannot use link here. :crying:
This issue is included in 4.2.2, and ADB is disabled by default for security.
I tested on my Nexus 4, 4.2.2 running. :fingers-crossed:
Okey. So to summarise: there is this new security feature in android 4.2. that makes the device show a popup if you want to allow the connected computer to use the adb = debugging bridge. But for this to work, you need to have the newest adb binary, which needs to print 1.0.31 when you run "adb version"
(found that info here --> http://www.androidpolice.com/2013/0...s-from-stealing-your-data-in-some-situations/ )
Under linux when you try to do it the old-school google-recommended way and download the huge "adt-bundle-linux-x86_64-20130219" and use the "android" tool to find new updates to the platform tools, it will tell you you already got the latest version which is rev 16.0.2 which contains an adb binary which will print version 1.0.26 which will not work with this new android 4.2.2 security feature.
So after searching for a linux adb 1.0.31 binary, I found it here:
https://github.com/mozilla/r2d2b2g/commit/2eefcc05366173ca51635da8f542fd8473ba0fea -->
https://ftp.mozilla.org/pub/mozilla.org/labs/r2d2b2g/adb-1.0.31-linux.zip
with that binary I finally can use adb on my nexus 7 again.

Thanks everyone root is successfully c:
Rooted went well... not the reboot
I was successful in rooting then attempted to install TWRP. The phone turned off then turned on with the "android open stomach and !" icon... it shut off a few mins later.
Now, all I get is the buzz when you power it on and a black screen. Im not able to enter the recovery mode using any combination of buttons.
LG Mobile Support Tool nor my computer will even recognize the device. Am I truly bricked beyond repair?
