After unrooting my phone to take to Verizon for some repairs, I can't connect my phone to a computer. I haven't connected my phone to a computer since I rooted back in March. And you don't need to connect to unroot.
I read somewhere that upgrading the radio will fix it but I'm not rooted so I can't. All I want to do is root again and I cannot. My mac doesn't see with osx or bootcamp, it and neither does my Windows 7 desktop. It's not that it's unrecognized, my computers just can't find it.
Is there some fix that I'm just not finding? Or is my USB port fried? I've tried another cable as well.
I can still charge so idk. I'm at a loss.
I had something similar happen to me the other day. I upgraded the hard drive on my netbook & then did a fresh install of Windows 7 Ultimate x64. upon getting it up & running, I plugged in my phone and it just said "USB device not recognized".
Seeing as how I ocassionally do wired tethering with PDAnet, I loaded PDAnet on to the netbook & then it specified to disconnect my phone & asked what manufacturer phone I have. I selected "HTC", it installed HTC drivers, then asked me to plugmy phone back in(with USB debugging on), then it said it was installing my phone and everything went smooth from there.
Right, but I don't even get "Unknown Device" or "Device not recognized". Absolutely nothing happens.
My phone will charge but neither device talks to each other.
you ate sure igs a USB 2.0/3.0 and not a 1.0 jack?
czn you trhy on someone elses pc?
normally wjen a USB jack goes out that's it.

Have you tried loading hboot then connecting?

Have you tried uninstalling your USB drivers, I had this happen and after a reboot it worked once everything loaded back up, search for a tutorial or I'll post when I get home

that *might* work.. if your PC is a store bought system, you'd just go to the manufacturers website and download the drivers from the 'downloads/support' page, then uninstall from device manager, reboot, re-install(and possibly reboot again).
if it's a custom PC, you'd goto the motherboard manufacturers page & do the same thing. if you don't know the make/model of the motherboard, it will also tell you in device manager(or just remove the side of the case and look at the motherboard itself, it'll be labelled somewhere near the cpu).

If by loading Hboot you mean loading the bootloader and trying every single option (even Hboot USB), then yes.

I can't even get the computers to recognize that I need a driver or that I have a device connected.
not sure if you've tried another USB cable or not, but if you have and it's still doing the same thing then it has to be a hardware related issue. possibly something wrong with the USB connection on your phone.
Awhile back, mine was doing something weird where when i'd plug it in to charge it and it kept showing that it was constantly charging, then not charging... I thought "what the hell!?".. I ended up trying canned air and it helped a little.. but started up again. I finally used some 'electrical parts cleaner' on it and ever since it's been functioning normally again.

it helps to read the entire post apparently ;P
well, in the time I've had my TBolt, I've tried out every radio & countless rom/kernal variations. I have never had an issue connecting to PC on any radio so I doubt the radio has anything to do with your issue.
You have already attempted everything else though(a side from the cleaning) so i'd wonder if there's some sort of issue with the software on your phone.
I have had this exact problem.. have tried different PC's, different cords, different usb ports...I have tried to mount under CWM also. Computers don't give any indication that there is anything hooked into them....the phone does charge however. I have reinstalled the ROM (using CM7.1.1) I have intalled previous backups which had no problems linking to my PC. I have not tried to clean the charging port..will give that a go...I feel I will have to by a card reader for my pc to read the microSD. worked fine for 6 months, but then just quit. Posted this problem on android central...but no one could figure out a solution, thought someone here might have....last post on my AC thread from someone with same problem was told by verizon/htc to send it back for replacement...don't want to but might have to do this...love to have a brilliant idea before I do though! Can't post the link to the AC thread as I am a new registered user here..been trolling all year...but you can find it under the Thunderbolt Rooting. ROM's and Hacks area.....
I'm pretty sure no one has a solution to our problem. I've taken compressed air and cleaned everything and still no luck. It's just a question of how much they'll charge me for it.
okay so i think i bricked my phone. its very strange like my usb got turned off but i have only installed infuse 4g roms so i have no clue how that could happen
anyways it will boot to the samsung logo and nothing else. even with a jig i made and tested on my friends nexus s (and every button combo for download/recovery)
any ideas? before i tried to reflash i was getting some weird problems like my phone would charge in sperts as if i was continuously pluging and unplugging the device. and i couldnt use the usb to transfer files

i have read countless but thanks for your input. i have not seen anything helpful. the only things close were known 100 percent to be a bad usb and not for this model phone. but regardless i believe i will be getting a new one in the mail shortly but i believe someone should maybe make a tutorial on replacing the micro usb inside the phone. although no way of knowing if that was the problem or not. hopefully they wont be billing me after they realize my phone was rooted with miui
So I got an incident with my phone, if you wanna now about it, its at my sig, but the thing is that I dunno why or how, sometimes my computer does recognizes my phone and display the Turn on USB storage option at the notification bar, but each time I try to turn it on it just wont work. Attached is a logcat whenI try to enable it, maybe someone could tell me why it wont work.
What rom are you running for those off that are on the xda application?

Normally I got two nandroids a GB based one and an ICS based one, right now Im using both Eagle's Blood 2.3.7 v2.8 and ICS 4.0.3 Build 1. But I had this problem since... always. I'm a flashaholic so i have tested actually every rom from stock 2.2.2 to beta 4.0.3... I even have a nandroid of my original ROM (the one that came with it when y bought it and rooted it) and not even there works. The only clue i have right now is that only if I disable USB debugging it will randomly connect.
This may sound dumb but have you tried a different usb cable? I had the same problem and tried my girls and my phone was able to connect each and every time. another thing I noticed with my phone is that it sometimes won't connect using windows 7...xp no problem but 7 it plays hard to get.

No man, doesn't sounds dumb, actually if you read the "issue" background on my sig, you'll notice that I have made all those steps... its not a big deal, there are SDCard Readers and the bluetooth but... itw not the same.

Ok but my bad I can't see your sig since I use the app most of the time. Yea its not the same

Holy Mother of God! I did it! In one of those "random" times my comptuter recognized my phone I just pulled out the batt unplug/plug again the cable, keeping both vol buttons pressed and it reconginzed the APX decive! Then all I had to do was NVFlash again, restore the stock 2.2.2 Nandroid i had somewhere and play a bit with the USB mount/debbug options, flashed both storages (using gparted for the microSD) and it works! Now have to restore everything to my SD and reflash latest cm7...
Nice!

Talked too early, if. I restore my nandroid the issue continues... -_____- Gonna try doing everything again...

Did you ever figure this out? Sounds like your having the same problem that i am.
I've tried at least 6 different cables, home PC, work PC, laptop and a co-worker's PC that didn't have anything vmware installed (had a hunch that vmware usb drivers were the cause). Oh, all the computers were win7x64.
I've only rooted my phone and upgraded to 2.3.3 so nothing crazy going on there and it's worked for months since i did both of those.
I have a feeling that this may have been a recent windows update, but no clue when or which one because i haven't really cared that it didn't work. If i had to guess i'd say mine stopped working about 3 months ago... again, hard to remember.

Make sure usb debugging is turned off.
Plug in the phone, enable usb storage.
Right click on the phone drives in the explorer and click on eject.
Turn off usb storage.
Unplug and plug in again.
Enable usb storage.
Drives should work now.
This did it for me. Since then if I remember to eject before unplug I haven't seen any issues.

Thanks for the reply, I'll give that a shot.
Curious though, when yours was having problems, did windows detect anything? For instance, when I plugged mine into my co-workers pc there are zero pop ups about new hardware detected.

I had the same problem. Dirt in the mini-USB port can cause that problem.
Take a can of compressed air and blow it into the mini-USB port (blowing with your mouth isn't enough). Also, take a close look at the port with a magnifying glass and look for any dirt or discoloration in there.
Do the same with your cable.
Not working after install RemICS 1.3.2

Hi, this problem occur to me after I've installed RemICS 1.3.2 ROM (CM9 based), I did follow the installation steps from beginning, when the problem occur, I did re-flash the same ROM several times, but this problem still unsolved.
I did try all recommendations (blow out dirt, disable usb debugging etc) but still not success.
This ROM should able to detect USB when phone connected with PC, but somehow I don't know why. Any experts recommendation?

Ok, I just found the problem. I can hear now the tone of PC detected USB when plugged-in, and I update the driver. then Voila!!
Thanks All..

Hey, just thought I'd register an account because I stumbled upon this thread because I had the same issue verbatim and I managed to get it working.
I ended up using the USB 3.0 ports on my desktop and suddenly it picks up my g2x without fail everytime. With that said, I'm lead to believe that perhaps its an issue of power. Maybe the USB 2.0 ports you're using simply aren't providing enough power. Not sure what its worth or if my issue was something unrelated but maybe that bit of information is something to work with. =)
Found another solution that fixed the problem for me.
If you are using Windows XP, log on as an Administrator and open Device Manager
Select View > Show Hidden Devices
Scroll down to Storage Volumes, and expand
Right-click on each entry and select Update Driver.
This fixed the problem for me!
Hey guys,
Ive been trying to fix my issues for the almost 2 days. i was trying to get UMS storage working using the tools that are around (in xda) and scripts, it was kind of hit or miss, somehow i lost my usb drives (i think the phone lost its hardware id somehow) bottom line i need my usb connectivity as that is the way i use the phone the most. i can still go into recovery, i flashed back into my nandroid but it didnt fix the driver issue, then tried new JB rom and still broken, almost like its the PC (i did try diff cables that use to both work) i literally must have flashed EVERY driver known to man and did fresh no driver installs, also tried using pc kies a couple of times so i have no clue.
if i hook up the phone to pc i get a usb device not recognized, adb has no connectivity and i tried manually loading the drivers but its like the phone doesnt know wtf to do because some adb interface drivers loaded it up (not anymore) but it would say it had error 10 ("device cannot start") and error 43.
upate. fresh copy of windows didnt help also the nexus has no issues on all the cables
Bump
Any ideas ? I cleaned the plug, used blow drier to heat the board up as suggested by a thread, reinstalled windows, kies, tried booting in download mode nothing worked. I almost sure my hardware actually lost its id. Is hwid contained in flashable portion? I know its not ROM data maybe nv items or anything else
It sounds to me that the USB connector on the phone is fried. I had the almost the same identical issue on a gs2. I tried 3 computer and no luck. So I broke down and had to send it in for repair.

Yea I kind of think that could be it too but was wondering if it is possible to flash the hwid portion or not. BTW any1 done a micro USB replacement ? Looks like it would be hard as **** and I don't have insurance. I suspect it to be bad though cause the stupid mhl adapter is finicky as hell too

Can you get Oden to recognize the phone? I was in luck, the phone was still under warranty from Samsung. And they fixed it for me for free.

Neg PC won't recognize phone at all. I am conflicted I honestly think there is something to the hwid issue. Is that flashable?

You might want to use mobile Oden from market and try to flash the stock Image and return the phone to factory. You do have a backup of your stock rom? Right!

So... I got a Tab 2 10.1 last week from amazon after 3 days of use the Tablet died, no power, no signal, tried charging and all troubleshooting I found through the internet in the ended decided to send it back and got a replacement Tablet from Amazon.
Yesterday I got the new one and let it charge all night, this morning I got to set it up, everything was working great until I decided it was time for me to root it and transfer some music to it. When I connected it to my pc i got an error message saying "USB Device is not recognized" error message said something like the device had malfunctioned. Funny thing is that the tablet charges perfectly, although I do know that the pins it uses to charge and data transfer are not the same.
Having hopes in my tablet and my luck decided to check if it was for some reason in USB Debugging, it was not.
*Removed Kies, and all Samsung related drivers, rebooted and reinstalled the drivers alone, nothing.
*Unistalled the drivers rebooted and installed latest kies...nothing...
*Tried using a friends cable to see if that was the issue, nothing. *
Tried cleaning the port, nothing.
*Tried both cables, mine and my friend's, on a different computer and still nothing!.
So I have ran out of options and ideas and I'm really frustrated as I can't believe I've so much bad luck as to get 2 damaged tablets in a row.
Is there anymore troubleshooting I can do before I ask for a refund? I'd really appriciate any help that you guys can provide me.

Yes, I am. Does it have to do with that?
Samsung's drivers and ODIN don't play nice with win7 x64. It works for some but not others. Use someone else's 32-bit PC, or try Heimdall Suite.
Posted from my Fascinate using XDA Premium
I've never had a problem with win 7 x64 with my Tab 2 10.1. What I would recommend is use a different USB port or try several different USB ports.
If that doesn't work, you likely have a bad USB port on your tab. Samsung should honor their warranty and replace it.
