ADB not working? - Galaxy S II Q&A, Help & Troubleshooting

Im having interesting issues with getting ADB to work...
I believe i have the android SDK installed properly, i can go to the command prompt and do ADB devices no problem, however my phone does not show up. Other guides online said to make sure debugging is on, which it is, but still nothing. Can anyone suggest what i may be missing? have any of you had this problem and know how to fix it?

Try typing "adb fork-server server" then open another window and try connecting with adb again.

Had the same problem. Install Kies and let it download the needed USB drivers; helped me !

[Q] 'ADB: device not found' looking for sulutions.

Here's the situation: Couldn't get retainroot working on previous occasion on my 64-bit system. Installed SDK on 32bit Win 7 system and was able to use both beforeupdate.bat and afterupdate.bat. Now...when trying to use any of the MODS available, adb cann't recognize my device and I get error messages like "psneuter failed to execute properly". I've done my searches on this subject in XDA but i don't think anyone else's experience is the same since the Atrix is a bit different. This is the first time i've had so much issues with adb. If anyone has any clue whats going on. I've all but given up on this device. I'm 14 days in with it and all headaches.

Make sure that you've mounted USB as "None", you can do so by pulling down the notification bar. Hope that helps!

make sure usb debugging is ON, set usb connection to NONE. I'm assuming you have sdk installed in c:\ of computer. Then go to cmd prompt and type: "cd c:\android-sdk-windows\platform-tools" [enter]
Then, type: "adb devices" [enter]
Should detect device, or something is wrong.
Hell, just go install the CWM and install the mods that way. A lot of them are updated to now work with CWM. See here: http://forum.xda-developers.com/showthread.php?t=1019143

ADB not recognizing device in debugging mode..Help

I am very comfortable working with ADB.
For some reason I cannot get it to recognize my device for the life of me.
Dameon Running etc. etc..
and then error:device not found
Help Please
Same for me .. what's the deal with Galaxy S2
Happens to me too, sometimes, but not only for the SGS2 but for the emulator as well (says "no devices online" even though it's running).
What so far always helped me was to give the adp.exe process a headshot via the Windows TaskManager (i.e. kill the adb process) and restarting it with "adb start-server", giving it a few seconds to settle and try again.
Which drivers have you installed? The google ones or the ones from Kies? Also are you running stock or using an AOSP rom?
hi, i saw this 3rd....i have the same problem. adb doesn't recognize my Samsung GS2. I enabled the debugging mode and set up the system but adb always says "Permission Denied". I use Ubuntu 10.04.
Please need help.

[Q] XXUFME7 no adb authorization prompt

So I went on trying the leaked Samsung firmware for my GT-I9300, everything seems fine, may be even better than the last one released here in Mexico, thing is, now that I'm trying to pull some files from my device via ADB it says that it is unauthorized, I searched for a while and I found that there needs to pop a prompt to authorize my PC to connect via ADB, but there's no such prompt. I tried checking/unchecking the USB debug mode on my device, restarting it, re-plugging it, different ports, ADB over the network, restarting my PC, anything that I can think of, and no luck.
Can anyone give me some insight on what can I do?
Thanks in advance and I apologize beforehand for my weird English.
Are you doing it through recovery? Are you rooted? Little more detail would help to get a better answer.
Rooted ?

ME7 is a leak (production build), "adbd cannot run as root in production builds" will always pop up.
i dont know how to fix this, but im pretty sure its a line in the build.prop and something in /system/bin.

I didn't find anything on my build.prop about that, also, no pop up shows, not the prompt to authorize my PC nor the one you mentioned

No, didn't tried it via recovery, I might try, but it may become a hassle, since I do this frequently. Also, I tried this before and after rooting it with no effect whatsoever.

Phone not recognized by ADB

Hey guys. I'm trying to root my m8 by using the toolkit. Well, I try to get the Token ID but adb fails since it can't find any devices. I've uninstalled the drivers, re installed, tried different sources, everything and I just can't get it to be recognized by ADB.
Anybody have any ideas? I'm running Win8x64
Regards
Smith
I'm having the same problem

Make sure your SDK is up to date, and that you are opening the command prompt from the proper location. Also make sure that USB debugging is enabled in developer options on the device.
I've had the same issue. I did all of the above and even tried on a Mac and adb still hasn't recognized my phone. Im on win 7x64. Still researching for an answer.
I'm not sure if this will hold true for everyone, but what worked for me was to updat the adp.exe and dlls. Then after I did that, ran the get token script from the toolbox, open the phone to the home screen, and accept the connection request from the computer.
I ended up having to just start the process over again on a different computer, but it worked, so I'm happy lol.

You can also try disabling USB Debugging and re-enabling it while the USB is connected. Works for me so far
