unknown device no matter what but was working fine - Samsung Epic 4G Touch

Yesterday i wanted to tranfer pictures to my Epic 4g and it showed up fine for a few seconds then disapeared and now all I get is unknown device in device manager on Windows 7 x64. Phone has been working since I bought 4 months ago. I did upgrade to FC05 modem in the morning without problems on Calkulin's 2.8.1
1. Tried different PCs and cables with same result
2. Wife's Epic 4g works on same computer and same cable
3. Reinstalled Samsung drivers and KIES in different configurations, no luck
4. Used kies to transfer Calkulin's 2.9.2 with CWM using format all no luck
5. Restored back up from last week no luck
6. PDAnet did not help
7. Messed with USB debugging and USB utilities no luck
Phone does not have any problems working, just pc won't recognize. I can install new ROMS that already have CWM if I transfer via KIES to internal storage and run from CWM, ODIN/Download mode does not recognize my phone. Is there any way to install ROMS without CWM and add it later if I can't connect to PC? Any ideas how to fix. Charging works and pc recognizes phone each time but does not know what it is.
Thank you.

You can use mobile Odin to flash kernel and get cwm ...there is a free lite version on xda

Thank you, I'll give Mobile Odin Pro a shot. Is it reliable or anything to watch out for as in the last bricks. In time I think I'll just replace the phone as I think the port went bad not sure how.

[Q] Flash back to stock FROYO EC05 via Samsung Recovery?

On stock GB EI22. Cannot currently use ODIN. More details on that here, for the curious: http://forum.xda-developers.com/showthread.php?t=1375005
Question:
In my current state, is it possible to flash a stock EC05 from the default recovery?
I could then use one of the root methods without ODIN, then get CWM, then flash back to GB using a rooted kernel / custom ROM...
Just flash an EC05 ROM, you are rooted right? Reread it...guess not. No, there is nothing you can flash from stock recovery that will take you back to EC05 from GB.

Thanks. That's what I was almost certain about. I will focus on getting that port to work again.

Give Heimdall a try. It has it's own drivers.
Sent from my SPH-D700 using XDA App
I had tried Heimdall from a Macbook Air as well (in addition to the other 4 computers I mentioned in the reference thread). It did not work. It did not do anything, similiar to Windows.
However, I did manage to get ODIN to work!!! Same setup I've always used, which until this incident, had always worked (same PC, same USB port, same cable, same phone, same person, same room in the house, etc.).
The only thing I did was uninstall the drivers completely, then reinstall, rebooting in between every step.
Afterwards, I opened ODIN, put phone in download mode, and BAM!, like magic, it worked again. 7 seconds later, I had CWM (ACS 5 1.0.0.0) installed!
Now, I am not sure it had anything to do with re-installing the drivers because:
1. I had the phone briefly connect once during the 4-ish day period... I was booted into Android, Windows did the USB connected sound and I saw "Samsung" under USB Devices in Device Manager. Then, when I removed the cable and booted into download mode, nothing...
2. I expected to hear the USB connection sound, regardless if the drivers worked on not. I would then expect to get a message stating "Could not install drivers" or something to that extent. Perhaps my perception is wrong?
3. No other computer, which had the drivers freshly installed, detected the phone, even with the same USB cable I know works.
Anyways, once CWM was in place, rooting took another few seconds. Ti Backup restored and all seems to be well.
Thanks everyone!
Yup. Happened to me too once. Out of the blue my computer would not recognize my phone with usb debugging on. Reinstalled the drivers and it was fine.

Was flashing my cousins Epic yesterday, tried to root GB with an online tutorial and soft bricked it. Used Odin to go back to ec05, ota'd to froyo (rooted immediately), looking to move to rooted gb(prob stock), and get MMS working for metro.

[Q] I lost my USB Connection with a Samsung Galaxy S2 Epic 4G Touch SPH-D710

I just installed the new Android 4.0.4 TBASGIIIv1.8 ROM for my Epic 4G touch and lost the USB connectivity with Windows-7. My computer will no long recognized the phone when plugged into the USB port and it worked fine with the Android 4.0.3 ICS FD16 ROM. It use to come up in windows saying SPH-D710 with a pop-up windows and with this new rom installed it will no longer recognize the phone. Is this a simple fix or problem with the new ROM because I would like to be able to download some of my files using Samsung Kies?
What ROM is the? And where did you get it from (link)? Team Rejects? How did you flash?

It’s the newest version of the ICS based custom ROM with the Galaxy S3 theme and all the detailed instruction are listed in this link: http://www.androidauthority.com/galaxy-s2-epic-4g-touch-ics-custom-rom-galaxy-s3-theme-93959/
I downloaded the newest version 1.8 from this thread link: http://forum.xda-developers.com/showthread.php?t=1673662
Everything works fine with the exception of the USB connectivity was lost and the computer will no longer recolonize the phone when attached via USB cable.
I download an app called USB switcher and made sure it’s on the mass storage but still inoperable.
When the USB cable connection is made the computer gives and audible note a will briefly flash a storage device for a second in the Computer – Devices with Removable Storage window then quickly disappears.
I’ve tried going back to the EL29 stock ROM about three times and the USB connection works fine with ICS Android 4.0.3 but doesn’t function at all with the latest ICS based custom ROM with the Galaxy S3 theme?
I'd first try to uninstall any samsung drivers you have on your PC then re-install them. Get em here http://org.downloadcenter.samsung.c...342248/Sprint_d710_USB_Driver_v1_3_2360_0.exe
Also try a different USB port AND cable.
If that fails I'd grab Mobile Odin from the market and download one of sfhub's one-clicks and install it (he has instructions for flashing from the phone on signature http://forum.xda-developers.com/showpost.php?p=23478866&postcount=869 in his posts.)

Ah I see. probably disregard my last post then.
Use sfhub's autoroot package to enable mass storage http://forum.xda-developers.com/showpost.php?p=24010029&postcount=889
That may work.
I tried uninstalling the drivers and reloading them a few times and even tried it on different computer.
I updated the Kernal using the PC based Odin3 v1.85 and flashed the EL26 stock CWM and might just have to try using the mobile version.

I had the same problem with my old et4g. I was running calks ics rom and kept getting the voltage to high notification and i wasnt even charging. And it also was no longer being recognized by the computer. Tried every fix. I went back to calks gb rom and still had the same problem with voltage notification and not being recognized. I tried to mobile odin back to a stock rom and it soft bricked my phone. It will only boot into recovery and i can get no where from there. Thought it may be the physical part itself so i ordered a new one and got my phone apart but the sprint version of the galaxy s2 is made into the board and im not quite sure what to desolder and solder

I just installed the latest stock FF18 Modem/Kernel/ROM and the USB connection works fine now.
My 4G signal sucks donkey balls on this FF18 ROM.
I tried just flashing the FG26 modem using this FF18 ROM but it's still a problem.
I'm going back to the FD26 ROM because that had the best 4G signal IMO.

You should still be able to use the download mode to flash the stock ROM using Odin OC without the phone being able to boot up?
The problem I always had was getting it to connect to the computer cause the USB port is jacked up. I finally jacked with it enough that it connects 1 time out of 5. Used the method u just linked and its back up and running. Hell yea. Thanx. Don't know what I'm gonna do with it now cause in already got a replacement and I don't think the ESPN is any good but I could always flash it to boost or something

How did you do that without USB connection? My phone has a problem and I need to get it completely back to stock for warranty repair. A week or so ago I lost USB connect-ability. I do not have ICS installed.

Download a stock rom to your computer, then use a wifi app to load it on your phone, use mobile Odin app to flash it.

Galaxy S3 Will Not Connect To Windows Computer

I am trying to connect my galaxy s3 to my windows computer and it will not install the drivers. Has anyone experienced this yet. I am rooted and running cm9 nightly. I also have a custom kernel installed. This was working when i rooted a couple of weeks ago. When I plug my phone into the usb it searches for drivers and display an error message that say it was unsuccessful at installing drivers. Any help would be greatly appreciated.
Have you tried uninstalling and reinstalling kies? I got a pop up on my phone when i plugged it in last time and it said it couldnt find the software but yet i was able to connect to kies and go into phone through windows.

I experienced a similar issue, it may have to do with the fact that I didn't wipe cache partition and wiped dalvik cache when installing zip from sd card etc... I don't know what caused it, but nothing I could do (including re-installing drivers a couple of times from KIES and tying it on a different laptop etc.) would fix it until I did a wipe data/factory reset by mistake! (instead of wiping catche partition) ;<( and that seemed to do the job!
Perhaps you may want to try doing a "wipe catche partition" and "Wipe Dalvik Cache" from CWM before tying to go ahead a do a "wipe data/factory reset"?

have the same problem
I did have that 'hardware ID missing' error suddenly after i was connecting my phone to my laptop just fine. my desktop has no problem. i did a few things that seemed to have fixed it or steps for a solution. I downloaded the TMO Samsung drivers. if you already have it installed, try uninstalling it. If that doesn't work, toggle USB debugging in between connecting and disconnecting from the computer. Other times, toggling USB debugging wouldn't work, so i toggled in between MTP and PTP. i play with a few times til it work. hope that helps. i can't post the link the the drivers yet, but get it from samsung's website.
i'm on gsm r6 and trinity kernel
Since I've gotten the phone I've had to keis air everything. Hardware I'd missing error on every PC/laptop I owned.
Up until yesterday. Plugged it in and keis opened. Connection troubleshooting joppy. It redownloaded and installed drivers. Like if always has...but this time it actually worked and so does my mtp now.
I wonder if its ROM related. Before I was using stock with the problem. The aokp unofficial r6 with the problem.
But now I'm running the official aokp jellybean release and it works.

From my experiences it only ever occurs when Kies is running, even in the background, while usb debugging is enabled. If kies isnt running then its all good.
I ran into this using CM9; seems to me that Samsung is using MTP protocol's now instead of USB. I just use Driod Explorer with debugging and I can move files without any issues.
If you are wanting to just transfer files to/from computer try SwiFTP. I love this little program.
Original dev no longer supports but its been picked up by another. Download latest version here.

From talking to Samsung Advanced Technical Help, I learned that, although it is never mentioned on any site or any literature, if you have
Samsung Studio 3 and/or Samsung New Studio and the USB drivers, uninstall ALL. I use Revo Uninstaller. Then reinstall the USB drivers from Samsung site. Make sure WiFi and Bluetooth are turned off,on the phone, and connect the phone. Should work.

I have a similar issue. This happened just after I rooted my phone. No USB connetion.....more or less. I'm now running Windows 8 and when I installed the drivers and connected my phone Windows starts the installation and it detects the SAMSUNG USB Composite Device and the SAMSUMG Mobile Modem but I can't access the SD card or internal memory. I changed the cable and reinstalled the drivers. I even installed Kies and it says that my device is not supported....any more ideas?
have you checked to see if you are in the "AP" mode when you dial ##8778#, you need to have a stock dialer for the codes to work on some custom roms the dialer codes will not work.
Default is set to"AP"
"AP" <----....xfer files
"CP" is used when programing to other carriers..etc...via CDMA Workshop.......
"ALL" <-----some people like to use this setting
didn't work

I had the problem when I was running the ParanoidAndroid ROM, I couldnt tell you how many times I odin'd EL26 and clean flashed. My usb worked fine after flash until I installed my apps using TB. So I went app for app, installed an app, plugged into my laptop. For me it was the simi clock widget whenever I installed that it would no longer link up to computer. I uninstalled it and am now back to normal.
Same here with Jedi Jelly 4 |4.1.2||Flashbar|| 1|17
Please help.
Samsung phone are REALLY picky about what cables you use. Some cables will only charge the device when you plug into USB, others will allow you to interface with a PC. The stock cable that came with your E4GT is the best to use, also the HTC smartphone microUSB cables work too. Hit and miss with LG and Motorola cables.
Do you have extweaks on that rom? If so you can force it to hook up thru the usb settings section.
When I originally rooted the same thing happened. It was almost like it had no setting to hook up to a PC. Only fix I found was driver sweeping the pc, reinstall the drivers, and switching roms untill one hooked up again. Repeat the driver sweep for each rom. It was a hassle but it worked. Landed on the blu kuban.

really? because I've been having the same issue and I haven't done any mods or anything with my phone yet...pretty stock. But I took it to a boost near me and the clerk plugged it at it got detected in no time.
I plugged other devices into the same USB_port with the same cable and the port and cable seem to be fine in my computer and no go, got the latest driver still nothing, and at some point I tryed to older drivers and still nothing.
I guess i'll have to try another uUSB cable. I only have one laying around
am running Vista x64, the pc at the store was running 7 x64 btw, not sure if that makes any difference

I've had same issue with Samsung Galaxy S4 (I9506). After a week of trying all available custom and official rom's I've followed pariah1570 advice to uninstall some apps and it worked! Great thanks. I don't know yet which app caused this problem, but I'm installing it one by one and checking.

[Q] UPDATED**** (SOLVED)No Data...and no USB to PC...now what? :(

UPDATED**** 1-23-2014
The USB issue was due to the port malfunctioning. I ordered a replacement part via Ebay for about 7 bucks and fixed it. Now I have PC access. As far as in updating the firmware...after 12 failed attempts via AT&T I just manually did it via Odin and now it is updated. Thanks for everyone trying to help me out. Hated it was a hardware issue and not just a tech/Soft problem :/
The past week I have noticed my Note 2 charging slower than normal. Sometimes randomly disconnecting and connecting when plugged into the ac adaptor. I figured it could have been the cable or the adaptor itself...so I replaced it. It seemed to work...but then it was acting buggy again. Then...lastnight I noticed when I was wanting to transfer a few file from my laptop to the phone...it would charge the phone but would not allow it to connect to the file system at all. I scoured the net for solutions and tried just about everything I could find...as well as the more simpler options as try a different cable...but nothing worked. I also tried it on 2 other laptops...no luck.
My phone was rooted...but never used a custom rom and so I decided to just unroot and do a clean slate in case there was something that borked. Everything went smooth...but now, after doing the unroot and factory reset...the usb still charges...but no connection at all. I went through all the settings and set them as they should and nada. On top of that while I do have my phone service...I have no data at all. I have called att and they were no help. Samsung passed me off to android customer service and they were no help. So now what can I do?
Problems:
-No mobile data available
-No USB to PC file transfer ability (kies air works...but not usb to pc)
-I also cannot update past 4.1.1. The updater says I can check again in 24 hours....lol
Ok...so I fixed one issue already. Found a solution to the mobile data network issue. It would appear that due to the factory reset...it lost all of the APN info for linking with at&t. I found how to restore it here: http://forums.att.com/t5/Android-Di...-Phone-APN-Settings/td-p/3467513#.Ustjil8e-Co
To fix the USB connection to your computer
You need to connect USB. Then, in dialer, dial *#7284#
Go to Qualcomm settings
Select MTP+ADB
Done."

Tried that...before I unrooted and even after unrooting. Still doesn't work
Try installing Samsung Kies on your computer and updating your drivers.
Or try a different cord it might be a bad cord.

Have you tried putting the phone into download mode amd see if it will read your phone that way?

Didn't think about trying that. I just attempted though and no luck either
This is irritating because ever since I unrooted and restored to original fw the usb charge works perfectly fine...no longer cutting in and out like it used too. But just cannot connect to the PC via USB for file transfers. Kies works fine doing that...but USB is no long an option
Have you tried uninstalling the old USB drivers for it then reinstalling them?

Yes...no luck
So I did a factory reset again just in case...still the same issues. USB will charge...but no connect. Kies and PC will not see it. Only kies air works. On top of that I have now attempted to update the firmware via at&t through settings and it fails EVERY time. It downloads 100% and after reboot and goes into at&t installation it always fails at 24 or 25%. 5 times in a row...for 5 days is ridiculous. Any more ideas?
At this stage I wish I could re-root it and then flash the original stock rom again to make sure that it didn't bork the first time. But I cant I'm assuming because I need to be able to connect via USB. Am I wrong? Am I wasting my time?

Since USB is charging. Can you check under device manager, what name it is showing for your device? May be you are missing drivers therefore your phone is not recognized by PC.

It doesn't show anything. The only thing that stops the phone charging when I disable or uninstall is what is labeled Renesas electronics USB 3.o root hub and host controller. 2 separate items. BUT...its not plugged into a 3.0 port anyway...even though in the past it has worked fine...for over a year no less. I have uninstalled that item...as well as uninstall the Samsung drivers before...rebooted while phone is NOT plugged in...re-installed the Samsung drivers...then plugged the phone back in and it still doesn't work. Still charges...and the item comes back...but no usb to pc file exploring capabilities. Same for other computers too. Have tried another computer as well...one that my phone has never plugged into. It charges...but no connectivity. The computers just don't even see it for some reason.
Is there a way I can root the phone without USB to pc support? I'm hoping to try and update it once rooted with ODIN.
You don't need root access to flash a stock rom. I was having usb-charging issues, and a return to stock 4.1.1 cured the issue. I replaced the USB board but that didn't fix it. So, stock would be my advice.
You could put the stock package on your SD card using an adaptor and your PC. But I don't know if you have a custom recovery.

My only thing is I have no usb to pc file sharing capabilities unless I use Kies Air. Otherwise I cannot. I have tried now 8 times so far to update the phone and I cannot. It downloads fine...but upon rebooting to install it fails everytime at 24 to 25%. All I want to do is update the phone. It is a simple as that.
Take your SD card out of your phone.
Put it in an adapter.
Put that in a PC with an SD card slot.
Copy the stock ROM to the SD card.
Remove the SD card from the PC and adaptor, then insert it in your phone.
Boot into recovery and flash the ROM.

When you say boot into recovery...are you talking about where I load rom from sd card...adb or something like that? And...can I do this for 4.3? I have 4.1.1 already. I was trying to update to 4.1.2 to see if it will fix the usb issue as well as the updating issue. But if I just had the 4.1.2 and flashed it would that do the same thing as updating?
