[Q] usb debugging failed

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

Have you tried a factory data reset?

Did this ever get resolved? I hate to see an open issue die like this.

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.

Possible Solution To "Vibrant Won't Mount"

I don't know if this has been brought up before (search didn't find anything), so I thought I'd share. Both my son and I have a Vibrant. I have flashed just about everything out there (can't help myself ), but he has yet to take the plunge. Anyway, I wanted to pull some video he had shot during the New Year's Celebration, and couldn't get his Vibrant to mount. It would do the usual business about asking to mount and all that, but my laptop wouldn't recognize it. It would recognize mine just fine. I asked if he had ever hooked his phone up to his PC, and he said that he had, but hadn't had any luck connecting lately. He also mentioned that he had recently bought a new charger for it. On a hunch, I looked at his charging port, and yep, you guessed it, one of the usb tabs on the phone was all jacked up. (it was pushed all the way to the back of the slot, like there was a bad fit on the new charger??) Anyway, with a little coersion, I put the tab where it was supposed to go, and VOILA!! Connection problem gone! I realize that this will probably only help a few folks, but I figured it can't hurt...And no, I didn't think about getting a pic of it prior to the repair, sorry....Oh and sorry for the long post
Cheers!

Good observation I had the same thing happen on the other side My laptop's internal usb connection had a piece break off, and it took of investigating to figure out what actually happened

My odin issues finally solved!!!!!!

I found this idea when trying to install heimdall in ubuntu - where nothing worked there either. Someone had one of the usual issues (can't connect to the computer) but then he cleaned the connection! I personally was trying all day on 4 machines and trouble shooting in between before I found this. It just all clicked - like the fact that at the beginning I could see it on the computer, now it sometime recognized as a unknown item but not always etc.
So if you found this you've like found all the usual stuff already: install/reinstall kies or the drivers, try different USB ports etc.
Well add to the list: clean the usb port on the phone with alcohol and the cable and the computer too. I did that and bang, like 8 proper drivers installed!!! probable because I had installed and reinstalled so many many many times. this was literally days of my life and hours of my sleep (including now to share but XDA is worth it).
Now the fellow in question apparently would use it as a boombox in the bathroom while having a shower (not sure how that worked) but in my case it was only 3 months old and never really wet or abused. But it still worked awesome!!!!
I can't believe I can use Odin finally! Good thing too because I have an i9000m with the dreaded SD card of death (which just came back from its 1st repair - hence the need to root it which with 2.2 is much more painful than 2.1 was.
Please thank me if it helped!
Oh and one other note. It would not just see in when going straight from cleaning to download mode. I had to do it regularly with the power on first and then I pulled the battery and went into download mode.
ahhhh I can finally get some bleeding work done - except for looking at custom roms now....
Oh - and I guess I should have backed up the existing firmware but I'll try and get that from someone...

I think I cooked my USB functionality.

Hey gang. Wondering if you can help me with a strange issue I've got. I can't seem to connect my phone to my computer via USB. Wondering if anyone could help determine if there's a possibility of repair or not.
==Possibly relevant info==
Samsung Vibrant
Android 2.2 Froyo
Kernel version: 2.6.32.9
Build number: FROYO.UVKB5
==End relevant info==
So, my USB is acting up. Has been for the last few months, where although it charges when I plug into a computer, it's not connecting to allow data transfer. I haven't been too terribly worried, this happened before then cured itself when I did a factory reset. The thing that usually triggered it was when I tried connecting to my linux box in media player mode. The phone would just kinda lock up, I'd have to restart it and then USB wouldn't connect. But after doing the factory reset it was fine the first time. THIS time however, since I'd just left it stock now I'm itching to flash a custom rom but even though I've wiped the whole stupid phone totally clean, it still won't connect. I'm trying to follow a method on an article on dkszone.net called "Bypass E - Signature Verification Fail Issue On Vibrant Android 2.2".
So it seems I need USB for the debug mode.
What I think my main problem is, and where I need some help, is that I had purchased a super cheapwad USB car charger off of amazon for like 35 cents. Every time I connected to it, my phone would ask me if I wanted to connect using kies, media player mode, or data storage mode. I thought it was annoying but didn't really think it would harm anything. But now that I'm thinking about it, it's probably been pumping 5v into each pin on the USB port, whereas the USB functionality uses probably 3.3v, and I'm afraid I cooked something.
The random part here though is that about 5% of the time it does (sortof) connect. It brings up the USB options when I want to connect, brings up the icon saying it's using debug mode, etc. But my machine just reports that it didn't recognize the USB device. So, I'm thinking it's on the fritz, but figured I'd check here to see if I could possibly find a ray of hope.

You can use ADB over tcpip. There's many a free widget to enable it on google play or Do it manually

Thanks for that, I had been wondering if there wasn't a way to do that over wifi. My issue is that sadly I haven't even rooted the phone. ADB over WiFi requires root, whether I do it manually or use one of those super sweet apps.

So anyways, guess what?
My brother in law has the same phone I do, and I grabbed his phone one day and plugged it into my computers and had the same problem as with my own, and I know he hadn't plugged into the same charger I had, hadn't tried the media mode on Linux like I had (which were what I thought were the big contributing factors). SO, I kept digging, found that I hadn't quite yet cleaned it properly. I'd tried my best to clean it but until I swabbed it well with some rubbing alcohol it wasn't as clean as it should've been.
Long story short, I'm backing everything up so I can start flashing roms.
Moral: just clean the dang thing really well

Ideos x5 totally bricked

Hi there,
My phone not turning on not without battery and SD not with home and volume+ and power button not with both volumes and power nothing at all not even vibrating when charging I am not sure if it's the battery but it was charged before I rebooted once rebooted it didn't turn back on I am on aurora ics and cwm.
I didn't have any problems with it partitions might of been wiped but I guess this would leave me with access to bootloader or anything or a vibrate on charge at least it happened as I was formatting another device but put the wrong sd on ubuntu so I started to think it might be the battery except it was charged unless it decided to leak all the charge in no time.
Also it doesn't do anything on usb or charge connection no vibrate no led no light buttons no nothing just nothing.

Sounds like my issue...
If in fact you did format the whole 3.69gb partition, then you wiped the phone.
So far, my only recourse has been to attempt a JTAG and install a bootloader.
I'm thinking that maybe I can try some form of "wire trick", like the ones used on the HTC Sensation, but I don't want to blow it up by shorting something unrepairable.
If you find another solution, please reply as it would be helpful to others.

nope i didnt format 3.96 gb it was 3 mb and it was shown as linux cd gadget also it worked afterwards until i rebooted next day then blackness the thing is i cant seem to find a battery to try with so i need to try everything first

The one I have here wouldn't start charging the battery until I force-fed the battery directly. (use a 4-5v charger and directly charge the battery for a couple of minutes).
Mine worked, but I made the mistake of formatting the entire partition (3.69gb), so now the phone does absolutely nothing.

I am a bit confused here so now when you plug it you can do something to it since it's charging? I guess I never did the 3.69 thingy if I am not mistaken..So lemme ask you if I tried the wall outlet for example instead of the USB to tv or laptop would that help to start it? I am thinking of replacing the battery and see what happens that's if I can find it here in Turkey the Turks always into the newest phones so this one is ancient to them to find a battery for...

Mine is in the same state. But I know that in my efforts to get it to start again I accidently wiped the the entire partition. Can't turn it on, can't get a pink screen, not a thing and haven't beenable to find any solution. So I guess all I can do is sit back and check the postings to see if anyone else has the same issue and knows of a way to restore the boot partition.

I'm thinking of trying to run MTTY 1.42 and talk directly with the qualcomm chip to send the boot files myself, but I need to know what I need and where it goes first.
I did this with the HTC Kaiser (AT&T Tilt) with some success.
That was on Windows XP though...not sure if it will run correctly on Win 7.
