Help connecting Epic to pc (yes I used the search and my issue isn't resolved)

Ever since I rooted I can not get my Epic to connect to a computer period. I'm about to give up and just deal with what I got, hopefully someone can tell me what I'm doing wrong. Before anyone decides to be a smart ass I have used the search function literally for days and have tried tons of things recommended with no result. I am the first to admit I'm an idiot when it comes to anything involving computers but I'm pretty determained to learn.
This has to be the phone because I have tried to connect to 2 desktops (1 running Windows 00 and 1 running the most updated Ubuntu), and 3 laptops (Windows xp, Windows Vista and Ubuntu). When I rooted I used the Vista computer and connected fine (can't anymore). I didn't have the space on the C drive to install the Android SDK so I switched to Ubuntu (first time user btw lol). Somehow when I was backing my SD card I lost any access to it or the notification bar. I never got my SD back til I rebooted but I haven't been able to connect to any PC since. When I charge (even in the car) it always tries to stay in mass storage mode. I basically charge in my car with my phone off hoping it will just charge and not mount my sd card to my car or wall lol. Yes I wiped 3 times, partitioned sd, tried several different cables (but my husband used mine and no problems on his Motorola) I'm sure I've done something wrong when I rooted or mounted to Ubuntu.
I also can't use adb. I followed the directions to the t (a few times lol) but when I run any commands it says "no such file or directory" I didn't have adb on the windows pc when I di noobnl's one click so I never ran the (adb shell ect) commands. I now can't do jack. I am now running noobnl's DI18 ROM with modem.bin flashed thru Clockworkmod.
I have tried all the basics you will find wit 2 days of web search.
My goal is DK28 (dream on Erica lol)...Thanks for any help and for anyone sparing me a lashing ;-)

When you plug in on your windows pcs...in Device manager..do you see anything appear? also do you have USB debugging on the phone?

USB debugging on?
Have you tried reinstalling the drivers for the Epic?
Rebooted phone and PC? (Sometimes it helps)
Used Odin?
Something might have been screwed up during one of your downloads, bad file maybe. Try reinstalling your drivers first, use Odin (phone must be in download mode), and see if it recognizes te device. If it does then Odin the stock .tar file and go from there. It'll give you a fresh start.
That's all I can think of right now.

I bet your USB debugging is on since most root's requier it. Even tho it says connect to pc if usb debugging is on it wont connect to my windows 7 box

I would suggest, if you're really having this many issues, just boot into download mode (1 on the keyboard + power button) and odin back to di18.

Just for kicks have you tried Settings > Privacy > Factory data reset? I assume that wiping does the same thing if not more but it's worth it to see if it somehow resets a setting that might be the issue.
What's left - software issue or Hardware issue.
Software:
hmmm...yeah gotta try connecting through Odin which uses downloader mode instead of USB modes...
Can Odin see your phone? Run Odin as admin with antivirus off, and proper samsung drivers installed. Then boot phone holding down 1 key into downloader mode. Connect to computer through USB port on back of computer (i.e. directly to motherboard) - does Odin identify something attached to USB port?
Yes - flash the dk28!
No - with Odin still on, unplug the USB cable, pause, and reconnect it. Still No? Try a different USB port on computer. Also try uninstalling and reinstalling the drivers - be sure to reboot the PC. If still No, then try on another computer, and as you did before, try different cables. Still No?? --> hardware problem with phone.
Hardware problem with phone: Look at the usb port in the phone - is there any junk in there that might interefere with the connection?
Yes - clean it out
No: phone perhaps internally damaged:
Solution for hardware damage:
You and husband clean up and go to sprint store.
At store - tech will know phone is rooted, so:
--Tech more likely to like you? You handle it, maybe even blame husband. Husband can silently attend and look sheepish, playing the part of 'me man, me dominate environment, me break fancy tech of wife, me sorry." Try to get free replacement phone while simultaneously promising never to let your husband root the phone again, or even touch it.
--Tech more likely to like husband? He goes alone, cops to the true story of how you rooted it and then was backing stuff up when it suddenly stopped working [truth from men? so sincere!]. Try to get free replacement phone while simultaneously promising not to let you in the house should you even attempt to root again.
P.S. forgot to add you might turn off the PCs firewall while testing, as well.

same here. I tried out the free tethering app the other day and with usb debugging on i coudl never get it to install the proper drivers. Without it on and the 64bit drivers installed Odin worked just fine.

I have seen many Galaxy S devices not connect to a computer because of a faulty USB cable. Had my girlfriends sister switch out 3 Vibrants only to accidentally try and connect it to a laptop with a different USB cable and I've seen two others not connect with the stock Samsung USB cable.

How I fixed the tethering issue
I've had the same problem with my galaxy s - connecting to the PC (Win7 32bit) just doesn't do anything. As a test, I had a friend with the same phone/rom (froyo, rooted) connect - and he was able to! It installed the drivers and it just worked. He disconnected, I connected, and now it's fine.
So, see if you can find someone with the same phone and see if they can connect. Makes no sense to me, but it worked.

I've had my Epic fail to mount before. Interestingly any time I had an issue it was with a Mac - it always mounts on a PC. I'll stop now before I open up a can of worms.
Best advice I have is get a Dropbox account. You can use that guy to move files from a computer to the SD card without having to mount to the computer. Perhaps you can get a factory ROM (with root of course) on your phone that way?

You can get a app from the market called SWIFTP (free) & connect to your sdcard via ftp server. This can be a temporary fix till you get your connection error resolved.

I have 1 USB port on my laptop that the Epic shows up as "unknown device" on. Works on every other port, and everything else works just fine on the same port. The factory USB cable is finicky!

cant access usb storage

When I plug it into my PC, the phone starts charging but there is no option to mount the USB storage...
any ideas?

THANK YOU!!! I've been waiting for someone else to have the same problem!!! I'm relieved it's not just mine. I'm assuming you did a manual install also? Is yours rooted? One person suggested ClockworkMod but I'm a little nervous about rooting. I've been doing the manual installs but that's as for as I wanna go. I can't stand the idea of bricking my phone.

My phone is new out of the box!
I found that on two Windows XP machines USB storage doesn't work. I then plugged it into a Win7 box and it worked perfectly. I also used a different cable with the Win7. Try a different cable and try Win7.

I have Windows XP on my work PC and Windows 7 Premium 64 on my home notebook and the USB worked fine on 2.3.3. Every since I did the manual install of 2.3.4 the USB functionality is gone. I'm thinking maybe the ROM is used wasn't incomplete. It's beginning to look like the only way to fix this is to root my phone

FWIW I did the manual update (full rom) and USB storage works fine on my Windows 7 Ultimate x64 box.

Yeah, I'm thinking maybe the one I installed wasn't the full ROM. As soon as I see people saying it works great I go ahead and use it. Do you know of any possible fixes without rooting?

No first hand experience, but would it be possible to download the full rom and manually flash it again?

Trying to figure that out. I've been told try ClockworkMod and go back to 2.3 but I'm trying to do it without rooting.

Try a different USB port
If the update was incomplete, the update would have failed the signature check. The first time I connected my Nexus S after manually patching to 2.3.4, Windows 7 Professional X64 did not detect it when connected. I unplugged it and used a different USB port and it worked. I then tried the original port and it also worked. I would try a different USB port and a scan in Device Manager before changing the ROM.

I also have Windows 7 Prof. 64 bit, but switching to different ports didn't work. It won't install the drivers. What else could that mean if it isn't the ROM?

I had this problem immediately after flashing CWM.
I booted into the ROM, then, while the USB was plugged in, powered off the device, and turned it back on. It then seems to work everytime I turn on the device, as long as I don't boot into recovery.

Me too

I had a the same problem with my SGS.
The trick for me did: disable usb-legacy-support in your motherboard-bios.

Have you tried re-installing USB driver from the latest android SDK?

Kind of strange, it was working great yesterday and today couldn't connect. Right clicked on android_winusb.inf and selected install and it started working again. Not sure what could have changed from one day to the next. But at least I know what to do when it happens again.

Never tried that. Doesn't that involve rooting or unlocking the bootloader? Both of those wipe the USB storage.

Don't have a custom ROM. All I did was manual bootload 2.3.4 on stock Android. The weird thing is when it's plugged in(charging only) and I turn it off, it starts to power down and then freeze. The screen doesn't go black until I pull it out. Then when I plug it back in it automatically powers back on. Basically, I can't seem to plug it in while it's powered off.

I have no idea why but my suddenly works again. Im happy but confused

You shouldn't need any drivers at all for windows XP vista 7 ect. Mounting your SD card, using flash drives... all use the same USB mass storage divice driver built into windows.

Rooted Evo will not connect to PC

I rooted my Evo with unrevoked3 a few months ago and since then (or sometime after) my phone will not connect to my PC. It will charge but that's it. I checked off the ask me every time I connect option, it's set to mount as disk drive. I am using the stock usb cable that came with the phone. I tried hard resetting, data wiping back to factory default. Still won't connect. Tried reinstalling HTC Sync. Doesn't recognize my phone being plugged in. I want to flash my phone back to stock so I can bring it back to Sprint but I can't bring it back rooted and I can't unroot it without using the PC. I have Googled and Googled all over but can't find an answer. I did a search here and there are similar problems but no solutions that have worked for me. Could it be the cable? It is in good condition as is the phone. Maybe the USB port on the phone? Those went bad on all my Blackberries. I'm sure this problem is expressed frequently but a response would make my day.

I am assuming you have a windows based PC.
Do you have any device driver conflicts in your windows Device Manager? I'd start there. Your computer wouldn't properly reconize your phone if you have some sort of conflict or you don't even have the right drivers installed.

Broken usb is a known issue with EVO, something about how it is soldered onto the motherboard. Are you running a custom ROM or kernel?
Have you tried mounting it in Recovery? You can always use a MicroSD card adapter to transfer files. I just use Dropbox.
You can unroot without your PC. Just download everything on your phone.
Download the S-On tool from Unrevoked. Flash it in Recovery. Check to make sure phone is S-On
Download the PC36IMG.zip restore to your phone, there is a thread with it in Development. Use Astro/Root Explorer to move the PC36ING.zip to the base of your SD card.
Go into HBoot and it will recognize it. It'll ask if you want to update, say yes. Let it sit and do its thing.
There is a guide in q&a about unrooting
Sent from my PC36100 using XDA Premium App

Yes, Windows based PC.
So I downloaded the S-On tool, moved it to the root of my card with Super Manager, then flashed it. Says S-On at boot. I rebooted my phone, moved the PC136zip to the root of the sd card. Rebooted with down vol + power and it checks for pc136zip but doesn't ask anything. I tried zipping it in recovery and it says bad. I tried another download site and did the same thing, doesn't recognize it upon hboot, so I tried zipping from sdcard, selected it, it quickly said some text about updating then nothingness. How do I know if it unrooted?
Edit: Also, I checked my device manager on my pc but it didn't show anything wrong.

Install terminal and type su
You will get permission denied if not rooted.
I have a working PC36IMG.zip in my Dropbox, if you need it tell me and I'll PM you a link

if u think ur phone is broke cuz u cant connect to pc after u rooted it, it isnt broke at all. my phone did the same thing after i rooted it. I don't remember exactly cuz it was a while ago, but u may have to turn on usb debugging in settings before it will recognize it. also u can go into recovery and mount usb to write to it

It might have to do with the drivers you have to install when you run unrevoked. It has been a while, but I am pretty sure I had to install a special USB driver to run unrevoked.

I had this happen to my phone last week after I used my computer to root two other peoples phones.
It makes no sense really, but while in recovery I connected to the computer to move a few files to the phone, and after that it was able to connect whether in recovery or not.
See if your phone can make the connection while in recovery.

Ok, so I brought the phone to Sprint after trying a different USB cord and they said the port is damaged. My new phone arrived today but I need to get my phone back to stock ASAP. I got it back to S-On but when I attempt the pc36img flash it says...
SD Checking....
Loading... [PC36DIAG.zip]
No image!
Loading... [PC36DIAG.nbh]
No image or wrong image!
Loading... [PC36IMG.zip]
Then the black bar loads.
Then it says.
Main Version is older!
Update Fail!
Do you want to reboot device?
I hit yes.
I still have SuperUser Permissions.
I've downloaded a few different pc36img.zip from different pages and this happens every time.
Edit: Probably wondering how I did this without a USB. I bought an SD Card reader and transferred everything through PC.

Try this.
1. Plug your usb cable into the computer.
2. Plug your usb cable into the phone.
3. Wait and listen for the little sound that tells you that the computer sees it.
4. Unplug your USB cable from the phone and wait about 2 seconds.
5. Plug the USB cable back into the phone, listen for the sound, then look at the computer monitor.
On mine, I have to do this to make the autorun window pop up running Windows Vista.
Shot in the dark, but thought it might help.

Noise doesn't happen. USB port is damaged, noise will never happen.
On the upside,
(I don't have 8 posts yet or I would show the download image) Updated version of PC36IMG.ZIP that worked. Just rename to pc36img and it unrooted my phone.

I'm having this same problem. Now, In this case, I hear the noise. Then a second double noise (like when you unplug the usb) This happens whether I am in recovery or not. Also, oddly enough, the thing works on my mac. It's done this through several different ROMS Right now I'm using synergy (which is great btw). I'm really at a loss here. Anyone got any other ideas? Like where I can find it in device manager. There are like 9 "root usb" devices
*edit* Also, I'm using window's XP proffessional. I've tried some trouble shooting but nothing is really working. Also it's being assigned a disk letter when connected, during the short time (like less than a second) when the disk pops up it says removable disk. I timed it and it's being assigned H, but it's being ejected almost immediately.

I think it has something to do with power being supplied in the cord. Maybe something to do with kernal? I dunno. But I plugged it into a usb port in the back of my pc, and it read it : /

USB problem with HTC Desire HD

Hey guys,
I currently recently installed a custom ROM from this website and for some reason now when I plug in my USB into my PC it comes up not being detected so when I put my phone as hard drive so I want to transfer music, it doesn't detect it. Can anybody help me if this is ROM problem or just my USB?

Hey,
Okay I disabled USB debugging didn't know it was on, still doesn't work says windows cannot find USB device not reconginzed when I connect the USB. For the Reinstalling usb driver I do not know how to this ~?

i have the same problem.. turn "fast boot" off and restart the phone.. this always works for me.. hope this helps

Hey, I turned fastboot off. Doesn't work. I ordered new usb cable.. hopefully this works and it was just a fault with the cable!
Sent from my Desire HD using XDA App

Usually this is a problem with the cable. Simple, cheap to fix. Keep your old cable around for charging though (nice to have a spare)

Is this problem with the USB still active?
If so try a different PC just in order to eliminate WinOS issues.
If not close.

Hi,
I have the same problem at some months ago. I tried the cable and pfone on another PC, and it works fine. So, I recommend to try it on another PC and reinstall your Windows.
brgs,
Herold

Had the same propblem! Turns out it was the usb cable, it charged fine with the cable but data transfer didnt work.

i also had the same problem since last week and still cant resolve till now...i try all the option that u gave(change cable/pc,turn off fastboot)....i even sent my phone to shop and they still cant detect.they said maybe the usb port is damage or some software that may block my usb port?is it true? anyone can help?????

USB BRICK in my INSPIRE 4G ( DESIRE HD)
Hi, all
I got a new inspire 4g last week.( equivalent to desire hd ). It was working fine. But now it does not detect the USB connection. It only charges when I connect to pc. No other issues. I have also noticed that during fast boot mode also pc does not recognize the phone as device. I have tried all the suggestion on xda but no luck.
As fastboot is also not detected by PC I could not format mtd0 and reconfigure it.
Can anybody have any other idea? If I change the main board how much cost will incur ??
Thanks all.

First of all.. you have HTC Sync installed right?
Happened to me initially as well.. although for me changing the cable and/or changing the USB port on the PC solved the issue. Have you tried these?
Also sometimes killing all apps on the device before connecting helped.
You can try accessing your device through ADB to see if its being detected.
And I really dont think you'll need to change the main board..

USB brick on my Inspire 4G
Thanks for your reply. When I go the phone ADB and Fastboot were working
well. There was no driver issue. Now even PC also does not detect the phone or any new hardware when I connect it to pc. I had working fastboot on both win7 and Linux (ubuntu) pc. Now in both OS the phone is not detectable. Windows device manager does not see any new hardware when I connect my inspire . dmesg also does not show my hardware when I connect my inspire to linux pc.
Please help or suggest me to investigate further. I know how to install and work with adb and fastboot as well as Clockwork recovery ( also ext recovery). Some people suggested to flash a new radio. I can flash the new radio via sdcard. But how safe is it ? My phone is S-off and made unbranded. Will flashing a new radio make my phone locked AT&T again? ????
Thanks a lot

As far as I know.. USB problem has no relation whatsoever to Radio. Radio is only concerned with the signal stuff. Flashing it isn't that risky if you follow the instructions... There's a thread in the development section about Radio's which explains it pretty nicely.
As for the USB problem, are you using a Custom ROM? Some ROMs like LeeDroid have USB detection problem which can be solved simply by flashing a different kernel like LordMod's.
What I meant by "Accessing through ADB" was if commands like "adb remount" or any adb command as such are working when your phone is connected to the PC? Or is it showing "error: device not found"?

Is it possible that you disabled the pop up?
If it doesn't seem to be a software problem, have you tried using a different USB cable? This would be the most likely problem for you, in my opinion.

The driver came on the root of you sd card when the phone was new. If that doesn't work try pdanet

Well, I already tried all these ways. Still not working. I even try to restore to the previous back up that the SD card is working by that time. But nothing happen still. Look like it is a hardware problem.:laugh:

Have you looked at the device manager for devices with an exclamation point? Make sure you have the "show hidden devices" checked.

On your pc re-install the phone driver but first uninstall the original driver through control panel>programs. After the uninstall, plugging in your phone to your PC should bring up the unknown device pop up (then the new hardware installation dialogue). If not then the pc isn't picking up your phone, check the cable, maybe try a different cable/ usb port.
If all else fails, some mytouch custom roms on these forums borked usb, there was a workaround for that, something you could flash. I remember seeing it in some of the threads... Wish I could remember the name. It was around Cyanogen 7.1 mods/ports (before rc 7.2 was out). Maybe somebody else remembers..
Sent from my Frosted Cherry ParanoidAndroid v 1.5a3

It could be a failed USB connector in the phone. Much, much higher probability than "borked USB". Especially if he installed several custom ROMs and didn't have anything.
Very easy to tell:
Boot to bootloader (power off, then power on + Volume Down), choose "FASTBOOT" (with VolDown and Power buttons), connect USB. If you'll see "FASTBOOT USB" showing up instead of "FASTBOOT" - it means USB is working. If not - most likely USB plug in the phone is dead, or something wrong with your computer's USB ports.

you need to install the HTCdriver before connected the myTouch to computer. I think I downloaded it from the official myTouch 4g website, some mytouches have it in their sd card...

It could be a failed USB connector in the phone. Much, much higher probability than "borked USB". Especially if he installed several custom ROMs and didn't have anything.
Very easy to tell:
Boot to bootloader (power off, then power on + Volume Down), choose "FASTBOOT" (with VolDown and Power buttons), connect USB. If you'll see "FASTBOOT USB" showing up instead of "FASTBOOT" - it means USB is working. If not - most likely USB plug in the phone is dead, or something wrong with your computer's USB ports.

Hi, I've tried your suggestion. And the Fastboot USB didn't pop up. So that mean something wrong with it. Do you have any solution for this. Appreciate your help.

If no "install driver" or "unrecognized device" popped up at the computer - just to be sure, try a different computer. If still nothing pops up on the computer - it means you have to fix the USB socket of the phone, and it means you have to submit it to a lab (unless you're good with micro-soldering and have all the tools, including microscope - but it doesn't seem to be the case). It's a physical problem, and can't be solved with software - no builds/ROMs/etc can make metal contact

You are right. I think it is the hardware problem too. Because I just got a Micro USB port broken and I went to the phone repairer to fix it. After I got it back for a couple day and flash new ROM. The USB is no longer working. Will return it to them.
Thanks for your time

I had the same problem. I just formated the system and then flashed the same room and that worked for me. Hope it helps

Well, I already tried this method already. Didn't work for me. I even restored to the previous back up via Clockworkmods to the ROM with SD card mounting. But still not work. Format SD card, not working too. I've tried all the method. I think it's a hardware issue. Thanks

What is this by the way? Is it the orignal ROM from tmobile? I already tried this event before you suggest me but it doesn't work either. Thanks.

R u trolling? Because if u can mount USB in recovery USB should be fine. Unless its your PC or some files on ur phone r corrupted. Try fastboot comnand. Fastboot OEM enableqxdm 0
