USB debugging no longer activates on my phone. Activating it in settings/applications/development brings up the "Allow USB debugging?" permission window. However, no usb notifications appear, and the phone appears to be a dead device to any PC it is connected to.
This started when I accidently got into the download screen from the phone options popup. The display showed the yellow sign, android guy with shovel, and message warning not to turn target off. Phone was not connected to anything at the time.
Searching found a couple of threads indicating that a battery pull was safe to get out of it. Did same.
Since then, usb debugging (or usb anything) has been dead on this phone. Other methods of usb access (thru usb settings) have no effect either.
Tried the following...
(1) restore to my last backup rom.
(2) numerous reboots and battery pulls.
(3) mount/unmount sd card in cwm recovery
(4) clear caches
(5) changed pc's and cables (all worked before)
(6) reinstalled usb drivers on pc (worked before, didn't expect it to help since issue is at phone end)
As you can see, I'm running out of sticks to poke the horse with. Does anyone have any ideas?
Update: new kernel didn't help, either
Update2:
(a) Can't do a restore via odin, which won't detect the phone.
(b) Updated my adb (which I don't use much). adb devices command will not detect the phone via usb.
(c) Installed adbWireless which allowed me to push a stock nandroid backup to the phone. Restored that, usb is still dead.
(d) Restored back to my superdark rom, usb is still dead.
Head scratch: I'd blame hardware except that it seems to be between the settings and execution. If it was purely hardware, I'd expect to see the usual usb notifications. Regardless, it looks like I'll have to revert back to stock and let Verizon figure it out.
Update3:
(a) switched to the new AOSP rom. Nice, but no usb.
(b) switched back to superdark since I like my speakerphone and the AOSP seems to be on hold. Still no usb.
Resolution:
My apologies for not posting a resolution. My bad. After the first few days the post kind of fell off the radar and I stopped checking.
Short version...dirty usb port.
Details...after a week or so, I saw the usb icon flash in the notification bar for a few seconds when I plugged it in for a recharge. Hadn't seen that in a week, hope springs eternal!
A thorough cleaning of the usb port using a paper swab dampened with alcohol restored usb functionality. Not much dirt came out on the paper, but it must have been enough to probably bridge the contacts somehow.
At present the phone is fully functional. The original Verizon cable seems to be a little wonky. I have an aftermarket cable that works fine. It may be that the aftermarket cable did some physical harm to the contacts in the port, or the original cable is going bad (I had something very similar happen on my Omnia). Not sure.
I now use the original verizon cable only for charging at work and use the aftermarket cable for usb connecting at home.
Bottom line...if your usb goes dead as described in the op, carefully clean the port.
My thanks to all who responded...
Download screen shouldn't have harmed you.
You probably are well aware of this, but sometimes it's the simplest solution: Is your usb cable unplugged when you are trying to turn on USB debugging? It will not let you if you are plugged into a pc or mounted for some other reason. Make sure your file manager and any other rogue app is closed. Again, it does sound like you have tried all of this, just giving my best shot ar an answer.
Other then that... Has anyone else had this problem? I haven't seen it in this forum before.
The most general solution to any issue on these fascinates is to undo whatever you did to break it, it's just difficult sometimes to isolate what that event was.
Swyped w/ XDA App. When in doubt, mumble.
Thanks for the reply.
USB is unplugged when turning on debugging. I've also tried turning the phone on with usb plugged in.
The last thing I had done (before accidently activating the download screen) was to install SiMi Folder Widget. Needless to say, it went away with the rom restore.
Also used ATK to kill running processes before turning on usb debugging. Also verified that I still have root.
I've buggered the phone up before but have always been able to figure out a way back (with help from forum searches). This one's got me stuck.
Tonight I'll try to figure out if it can be odin'd back to stock and rebuild from there.
Again, thanks. All suggestions/advice are appreciated.
See op for steps taken to (unsuccessfully) solve this.
Can anyone advise how I can flash back to stock DI01 without using odin, since it won't detect the phone? I can push files to the phone via adbWireless but that's about it.
thanx in advance...
I dont know if you fixed it or not, but here is a stupid question. Are you using the cable that came with your phone? I have several cables that will only charge my phone and only the stock one enables data transfer. Hope this helps. Good luck

This may be my problem! I'm having the same similar effects. Although mine randomly shows the symbol but also says my usb is connected when it does. I've been trying to solve this for 2 weeks now! I hope this is the solution.

common problem
This must be a common problem because I've had the same issue. switched cables and viola, all good.
My exact problem solved:
USB debugging activated on phone but computer did not detect it at all, nothing what so ever. Not even on dial-up mode, or download-Odin (yellow triangle).
Drivers installed (Fascinated and Nexus for the hell of it).
Tried to ADB my into it both from windows 7 and MAC OS-X.
Hell I even tried a different USB cord.
I would get the USB debug icon in the status bar only when on windows7 machine.
I cleaned the phones USB port with the alcohol damped paper towel/tooth pick and the **** worked, first time.
Man I gotta thanks God for this site. I been ****ing with for 2 days.
Then this lil SOB acted as if nothing ever happen. I wanted to beat the hell out the lil ****er. But we are back friends now.
Thanks dude. This **** needs publicized more. I went through a few links before I found this.
I would and tell people to use something non-metallic and removed the battery beforehand. I did just to be safe.
Last week when I plugged my USB cable into my phone, it acted normal. The screen where it asks me if I want to connect USB came up, and I said yes. Everything was normal. It was baller.
Today, that doesn't happen. The screen doesn't come up and all the USB cable does is charge my phone, much like the wall plug does.
I've tried to install USB drivers, but they always require me to find "Android" in Device Manager, and it's never in there. The USB cable is doing nothing but charging my phone.
I managed to add a few mp3s over wifi, just to make sure that was actually working.
The phone is not rooted, (I was actually just going to try to do that) and everything is stock aside from a few apps.
I would really like some insight on this, please.
Do I need to get the phone replaced? Am I doing something wrong?
OK, I new to this, but thought I'd comment. If USB debugging is turned on, my seems to do that.

I've done nothing to the phone. Only installed a few random apps.
sorry to hi-jack your thread!
mine does exactly the same, but all i've done is manually update to 2.3.4 and my usb hasn't worked since, like you i've tried installing the drivers and that's done nothing and its also in usb debugging.
i don't know what to do or how to get it to work again, all my searching on here and via Google don't bring up much

Put your phone into bootloader mode and try whether it detect or not?
And also, see if there is two line of words written

Wow, you're right. My HTC cord worked. Thanks a lot.
I have had this happen on to me and have determined that a) the long cable that came with the NS4G is unreliable when used for USB connectivity with my PC. Shorter cables (even the shorter Samsung cable that came with my Epic) work consistently. I am guessing that this is a USB Bus power issue and some people will have better mileage than others using the stock cable, depending on their PC.
b) on a few occasions, it seems I've somehow borked the PC's USB controller and the PC wouldn't recongnize anything until I rebooted it.

I searched a few times on this forum and on google.com no luck. tried to adding a recovery file manually and zip it as update.zip and install from bootloader no luck. (use file explorer and dropbox to get files on to phone).

Was your phone rooted at any point before the issue? Not sure if they would fix it under warranty for me. I will call Samsung and see.
Thanks, I tried that but no luck. Still need to tried other cords. Also.
My phone developed this problem a couple days ago. I haven't done much to troubleshoot it...figured the port must be damaged.
(Not using the Samsung cable, btw)

It might be the port. I will have to get a samsung cable and try it, but i doubt it will help. Plus i can tell Samsung I tried everything. (I looked a ticket, but they said get a samsung cord, they don't trust the Palm Pre cord i am using).
I had to downgrade to the HTC Hero until i get the phone fixed.
By not working, I mean that my device isn't recognized in windows. I have installed the proper samsung drivers, I have turned debugging mode on and off, I have also swapped cables, all with the same response. "USB Device not Recognized" It works fine on my home machine but I am currently on my laptop and need to get data off of it. I am using CleanRom so I am not sure if that changes anything. Any suggestions?
What kind of phone is something you should always mention, a Samsung Galaxy, Android version __ etc… But always leave debugging on, always. There could be a problem with the computer not recognizing it, it's happened to me. Or it could be something with the phone but more info would be more helpful. Never mind I didn't see it was under att gs4.
Sent from my brain to your eyes, to your brain, using my Galaxy S3, running Cm 10.1. I'm in your head now.
Make sure your drivers are correct and up to date. Make sure you hit "accept" on any messages displayed on your phone (connection). Make sure the USB cable you use is working,. Try another USB port on you PC.
You said you did many of these things, but I would check them again. You can always try to see if ODIN or KIES detects your phone. If not, it is most likely a drivers / cable / port issue. Good luck.

Figured since it was Galaxy S4 forum that might be obvious, but it is the ATT version. Still no idea, gonna reboot in a few to see if that solves it. Will report back
Didn't reboot system, instead I turned phone off and plugged it in waiting for it to show the charging symbol, turned it on, windows saw it fine.
I have a quick question. It seems that my tablet has lost its ability to connect through USB recently. I was unable to send pictures to the pc one day and have bought numerous cables to no avail. Looks as if, somehow, it just wont connect through usb. The original cable was acting up during charging anyway. My main question is, how do I root without the ability to connect to a pc? Is this at all possible? I was rooted before but since installing the newest update, 10.6.1.27.5-20130902, i noticed it wasn't rooted anymore.Am I pretty much SOL? BTW, nowadays the tablet wakes up and beeps like every other minute while charging. Dont know if its related. I wish I didnt do the update altogether.
Updating to the latest firmware (at last check) hides the developer options from the settings. Your problem might be that USB debugging was disabled or never was enabled.
To add developer settings back into the settings, you need to go into the "about tablet" in settings and tap the build number 5 or so times and then developer options should show up.

If its a cable problem, the cable only costs 5$ on amazon.
I'm on my third replacement cable already. Also, developer options are turned on. USB debugging is on as well. They charge fine but connecting them directly to any computer i have does nothing, almost like not plugging it in at all. Have tried on three different setups that worked before, Win 7 X64, Win 8 X64, Win XP X86.

Disable the developer options and USB debugging. Windows may be trying to recognize the ADB instead of trying to mount partitions.

Tried that too. Doesn't seem to work either way.
Which worries me severely.
If you haven't already, install the google sdk adb drivers and see if that works, though from what it sounds like that's not the problem.
I'm thinking bad usb port on computer... try wireless adb if you can...

might be that the plug at your tablet got damage some how? maybe not fully damaged but partialy, do u have a dock? if you have you have any problem with it?
sorry for my bad english
Greetings!
Don't have the dock. Went to the Best Buy out here and they don't got it. Worst case scenario, my port is jacked up, can I still root without it? If so what steps can I take to do so?
depends on if you have a custom recovery like twrp if you do, then you should ok flashing supersu package, otherwise you are in the worst case scenario...

Hello all!
I'm just guna say, this might get long winded so, TLDR, Nexus 7 has no OS, I can get into the boot loader, the only thing I can actually do is get into TWRP v2.8.01, computer doesn't recognize it, can't get it to even see a flash drive that I've formatted to Fat32, now what?
For those who want some background. I got my N7 refurbished from ebay, if that matters at all. First thing I did was update it to Kitkat and root it. Installed some apps and was happy with it for a few months. About a month or so ago it stopped connecting to the Google Play Store. I wasn't bothered by it too much. But as time goes on, I find new apps and would like to use them. But obviously can not.
So, just to be safe, I wrote down all the apps I still had on it just in case they didn't want to load back up. Did a factory reset, still couldn't connect. Looked online and cleared caches and stopped services. Still didn't work. When I went onto the GPS, heh, on my computer it said that I had no devices so that was a clue of some sort. I could still go onto Youtube and log in and use it just fine. Just nothing in the store. So I decided to try something else.
What that was was to clear all my data with TWRP. Went to put in my email and password, couldn't connect, tried another wifi connection, still no go. I was able to use it, but the Play Store still didn't want to play nice. So in a bit of, "rage" we'll call it. I formatted it and now I'm where I am now. With a tablet that won't boot, just sit at the Google logo for up to 5 mins, as long as I've let it sit there for anyway. I have downloaded the Nexus Root Kit and tried to use that, but my computer won't even see my N7 now. In the bootloader or TWRP. So I can't even get anything onto it now.
So, what now? Do I have a bricked tablet that won't do anything or is there something an Android Guru out there can help me with? I'd like to keep it. I mainly used it to read and for various videos.
I have posted on forums.androidcentral but after a week and almost 300 views, no one has made any comments. I'm sorry for my ignorance if I'm missing something.
Thanks! I shall be hoping for good news.
So, does ADB recognize your tablet or not when you type "fastboot devices"?
I take it you mean shift+right clicking in the platform tools folder, open command window here, and typing that into the command prompt? If so, then no, it doesn't show up.

Can you go into the bootloader? Did you install the right drivers?
I can get into the boot loader just fine. Recovery sends me to TWRP 2.8.01. I've got the drivers from the Android SDK Manager, Rev. 11 apparently. Would that be any different from the standard drivers that get installed when you hook up the N7? Well, when it works?

That is correct. Use this: http://forum.xda-developers.com/showthread.php?p=48915118#post48915118
And if doesn't work check in device manager.
If it works flash the latest factory image and then you will be good to go
I've already had that installed and set up and nothing pops up in the device manager. I've also tried all the usb ports on my computer to no avail.

Then try the driver manual in nexus root toolkit
I can follow the instructions, but that doesn't resolve the fact that my computer can't see the Nexus .
go into device manager and delete every single entry that suggests anything to do with a phone, tablet, google device, nexus device, ETC. if you dont do that first, this will probably not work.
once you delete every single entry in there, go to the top command bar and somewhere in those menus is an option to show disconnected devices. delete everything again as above.
now, does your tablet still charge on the AC plugged into the wall? does it still charge when plugged into the computer usb? drivers are NOT required for usb to supply power. if so, the usb connector is probably OK. if not, your usb connector may be toast.
next, connect to the computer. does windows show any device connected? if not, try a different usb cable. report your findings back.
Sorry for the late reply.
There is nothing in the device manager related to my Nexus, which is odd, it had entries for flash drives, a camera, and my phone. All of which were in the disconnected devices. I got rid of just for the sake of it. Nexus charges just fine, either from the wall or any of my usb ports. If there is no way to make ANY computer see my Nexus, is it safe to say it's bricked?
I do have a cousin who's fluent in Linux if that means anything. I know that Android is a flavor of it. Might work better if both devices speak the same language. Grasping for straws I know.
Again, thanks for the help fwayfarer, GtrCraft, and Fobos531!
If I am reading right, you did NOT try a new USB CABLE yet, did you?
Try a known good USB cable, what I mean by that is try a cable you KNOW works for data transfer on another device and report back.
Connecting it to a Linux machine isn't going to make any difference in my opinion.
I have 2 cables and they transfer things just fine with my phone and my Kindle. I just downloaded everything off of both things, and transferred them back. No issue with the cables. I just popped open my Nexus and it looks like the usb connector and ribbon are fine. I did wiggle them a little but to no avail.
Pull the battery cable, smash the power button for a few minutes, reconnect and try again. It won't recognize a USB thumb drive in bootloader or recovery to my knowledge, BTW. I noticed you mentioned it not seeing one.
I unplugged the battery, hit the power switch for a while, plugged the battery back in, plugged the usb back in, nothing. Still nothing. I had read before that you can put the version of android you wanted on a flash drive. With an otg cable you could use that to update/install what you wanted.
You're probably right, I haven't tried using one in recovery for a long time. You didn't change the battery or anything recently did you?
Nope, haven't replaced anything in the Nexus. The only thing that I could think of that could be wrong is the usb connector. But for it to "fail" at the same time I formatted everything, too much of a coincidence.
Over a week bump
I ran into a similar problem about a year ago. Unless your tablet is connected to the computer you will not see it show up it the windows device manager. You should be able to connect your N7 to a work computer & it should go out for the drivers. If not, then you are Sol. You might have a blown main board.
The only thing my N7 does when I plug it in, is that it charges. That's the only thing I can get it to do. Well, this sucks. If I really have a bricked, or worse, tablet, it's still good for its screen and other bits.
