Computer not recognizing epic - Epic 4G General

Anyone else this problem? Rooted my epic with the all-in-one method a week ago, worked flawlessly. Today when I plugged my phone to my laptop (the same one used to perform the root) it did not ask the 3 options (charge, mass storage, or tether). Turned on debugging again, and no orange triangle on my notification bar. I have connected to my computer several times sinced the root and it all worked until this time. Seems as if lost my drivers somehow but I never did anything to do that. Any suggestions?

Try rebooting the phone while plugged in. I have to do that in my Mac, and I'm running a custom rom, but it doesn't hurt to try it.

Try a different usb cable. The stock cable is **** and my pc would never see my phone using it. This is a common problem. Monoprice has them super cheap if you don't have an extra to try.
Even if the stock cable worked once it can be flacky. The other thing is make sure you use the usb ports on the back of the pc.

Battery issues, what is my best course of action?

Currently on dirkk's 1. 1 uv kernel(voodoo) and the superclean Rom
My phone thinks the. Usb is always connected and flashes between "fully charged" and real battery level. Also getting a lot of force closes for process. Android. Acore. It's quite frustrating. I have tried clearing battery stats in clockwork mod. This combination worked fine until about a week ago.
What else should I do? Start over? Try another Rom?
Thank you!

im no expert but i blame voodoo. try uninstalling it.
-removed voodoo
-installed a new kernel and ROM (superfast and blackhole)
The problem persists
The phone thinks it is connected to the USB when it is not, and also getting a force close for process.android.acore every few minutes. FML
Wipe the dalvik cache and batt.stats again and try another cable.

Tried and tried.
Have brought the phone back as close to stock as possible without using Odin. That's my next option. No force closes but the USB and battery issued persist. Geek squad warrenty might be worth it: x

You have a one year warranty on the phone. If it's a genuine hardware problem, take the phone in and have it replaced.
Its looking like a hardware issue, I used odin to get it completely stock and the issue is still there. USB thinks it is always connected (which made it a huge PITA to get into the SD card to add files or use ADB) and the battery life is everywhere. Also wont boot without a USB cable plugged in. Very interesting hardware issue, my guess is the USB port got buggered up.

No usb available, other options?

I have a very strange issue going on with my fascinate right now. Before I go into too much description, here is my setup, to see the big picture. Rooted, stock vzw with geekniks stupidfast for DI01 (thought original kernel was original issue). I've tried to force the ota to DL09 and I get "IP_PREVIOUS_UPDATE_FAILED" as it fails to verify the dl signature.
Ok, on to my true issue. When I plug my SF into my pc, I get unrecognized usb device. I have the drivers installed properly and have previously been able to use odin via usb. My pc doesn't see the sd card mounted or anything. I'm debating unistalling the usb hub and restarting the pc so it will pick it back up as a new device. I have debug mode and unsigned checked, however, the little red triangle is no longer present like it used to be. I also every once in a while have issues with my battery level being accurate, as in it shows 100% when its really at 36% etc. It still charges, and recognizes being plugged in (haptic and audible confirmation).
Anyone have a clue or suggestion? I'm new to android, but well versed in the pc world. I just installed the android sdk in hopes of maybe doing a wireless adb push eventually. I'm A) trying to correct the issue and update my os/rom, or B) somehow get me back to stock and unrooted without being able to usb odin, so I can swap out for a new phone.
Thanks in advance for any help, whether it works or not.

so you are on stock vzw but you have used odin before. Did you use it to get clockworkmod on the phone?
did you return to stock from dj05 or dl09 OR have you always been on stock rom
I used odin to flash cwm. I'm on DI01 upadate-1. Had done the first update ota, then rooted and flashed cwm. I have been running that since until today. Thought kernel may have been issue, so flashed geekniks kernel for DI01 and have seen no change, except better performance as was expected. That is where I am now. Thinking about going back to previous kernel, but this seems better until I decide what I can do. Original nandroid and other in betweens to date still manifest the issues, which are only recent, like last few weeks.
Thanks again.

Does not see the Samsung SD Card
I have had similiar issues since DL09.
Try turning off your phone then reconnect USB after it reboots.
Seems to want to see it as a CD Rom.

I've rebooted my phone and pc, multiple times, no luck. Oh, one other thing, I tried popping the sd card into a card reader and I was able to see the files briefly, and upon trying to select anything, it totally disappears from view, as in pc doesn't see card anymore. Now I can't get the pc to see it at all. So I can't read/write it that way. My phone still sees it and can mount and unmount for removal on phone itself, but not with the pc.

Try flashing a different kernel. My first fascinate was picky with which kernels wanted to work right with the.usb connection.
Sent from my SCH-I500 using XDA App
In my experience, you can still use ADB to push and pull things from your device even when your pc doesn't recognize your device. I know this doesn't help with flashing DL09, but it could help you push a different kernel to your device (or you could download one from xda forums via the xda app). A different kernel might clear up the issue for you. Good luck!
This fixes it....

For your first issue it is because you are rooted you will not get ota updates. You should use odin and flash DJ05 imo it is much better and there are more ROMs and kernels

Thanks for all the help, I'm going to give it a whirl later and see if it works. I'll let you know.

Before I get too far deep in, could I just unroot via a terminalapp and then force the OTA to get me up to speed? Would at least like to see if I can deal with the minor malfunction while still being current.

This won't fix the problem because he is not on DL09. It will likely make his problem worse. You might want to read the entire post b4 you give suggestion.
To answer your question sir: if you can't get your pc to read your sd card with a card reader, the problem most likely has nothing to do with your phone. It probably is a corrupted|damaged card. It could also be a problem with your computer (this can be ruled out by successfully connecting another usb device to your computer).
Most likely, you will have to buy another micro usb card.
Sent from my Vanilla Froyo Fascinate
Ok, been trying a few things, and I'm starting to lean towards the sd card being corrupt (as one of the issues), sending my important pics and backups of my contacts, sms, etc to dropbox as we speak. I actually tried the SV kernel from adryn, and my phone has seen no ill effects (possibly no haptic, but didn't care at this point), everything seems to be working just like nothing changed. I actually briefly got the USB debug icon up for a second and it said usb connected, however I was not connected to anything, lol. It had done this on the stock kernel as well. I've booted my phone without the sd card in and it starts up normally, but the USB debug icon is still not present, even though the option is ticked on.
I can still force my phone into download mode, however my computer still doesn't recognize the COM port, so odin is out of the question right now. If I were to get my hands on the stock kernel again, could I factory reset the phone, remove root, and potentially force the OTA and then reroot? I've seen some options for terminal apps where I could ru superuser and busybox. Any thoughts on that route? I may give my roomie's pc a try, when he's out, as well to widen my test field.
Well, I got my pc reading the card via a card reader, but not while inserted in my phone. I'm going to try to uninstall the usb hub on my computer and restart my pc with no usb periphs connected. I read somewhere that someone was able to get the phone recognized again, but I have a feeling that it isn't going to work, since I never see the USB debug icon anymore.
On a side note, I get a com.android.settings force close message somewhat frequently, on stock, geeknik and adryn's kernel. I've started unloading apps left and right, but no avail. Thinking I need to get back to full stock somehow without odin. Suggestions?
I had similar issues. No usb, battery flashing to 100%. Tried everything as you have. Couldn't figure out how to get back to stock without odin. I'm running DJ05 superdark with geeknik 1.54 kernel.
This went on for a week and I was ready to give up and go buy another phone when one day the usb icon flashed momentarily when I plugged it in to charge.
In the end, it turned out to be a dirty usb connector on the phone. Cleaned it with a paper swab dampened with alcohol. I still have no idea why it was so sensitive to the small amount of dirt that came off it.
Hope this helps.
Well, I tried the alcohol swabbing, and it mildly worked. I get the usb debugging icon more often, but it also shows that the usb is connected, even though it isn't. My pc briefly recognized it once. Would I be able to disassemble it and clean or replace the usb port myself?
I've even blasted it with compressed air.
Sent from my SCH-I500 using Tapatalk
You've gone farther than I had to. I didn't need to resort to compressed air.
Do you have more than one usb cable available? I had bought an aftermarket one in addition to the one that came with the phone.
The original cable is still wonky on connection. It charges ok (no more battery jumping to 100%), but usb recognition is a fifty-fifty proposition. The aftermarket cable does charging and usb correctly.
I have had to reset my PC's usb drivers once by rebooting the phone while connected (the PC recognized it as a CD-ROM drive). This may be coincidental or an indication of a chronic connection problem.
I speculate in my case that the aftermarket cable distorted the phone connector somehow so that it doesn't like the original cable any more. Pure speculation.
Anyhow, glad to see that you're making progress. I know how frustrating it was for me. Keep us posted.
I had the same problem at one point. I found out that if your turn the phone off, plug in the usb cord from the computer, then turn the phone on while the phone is still plugged in. once the phone reboots, unplug the phone, then replug the phone in to the computer and then the computer should recognize it. This works for me every time that i have this problem

Somewhat unreponsive when connected to any usb
I have a problem whenever connected to any usb. I cannot unlock the phone. I do not get a response to certain presses. I cannot write a text (random letters are pressed). I use my NS as an alarm clock. I have to set the alarm and put the phone in clock mode before Docking (whereas it becomes unresponsive after connected). I have gotten the same results using USB from a computer, charger, and car charger and have always gotten the same results since having the original 2.3.1 to 2.3.3.

[Q] Usb not recognized by anything all the sudden

Ok so makes no sense ive not had any problems like this. Ive had my phone for months. All the sudden last night i plug it into my ps3 to move over a video file and Boom. the Ps3 freezes in such a way that all the controllers stop working and i cant do anything on it. Unplug the phone and after a few seconds things go back to normal. I plug it into my Usb hub (4 way splitter from Tmo) on the ps3 and it works (albeit very very slowly). Try to go back to just the ps3 and again it stalls and the pc wont even see it. Today trying to fix the problem ive changed to 4 different roms, tried mounting in recovery and tried to get my PC to recognize it every way i know and nothing is working. The charging light comes on but nothing else seems to happen on the ps3 or computer. Thanks in advance pros
Bump. Please help if u can guys. Thanks
ooo i had this issue earlier this week, installed like 3 different roms and it wouldnt see it, but all of a sudden it came back up.
what I did was wipe data/factory, cache, davlik, went into mount and storage formatted everything that gave me the option, mounted usb and installed Royal Panache rom. rebooted twice and it showed again.
hope this can help you.

So i tried both ideas, interesting results. I had already tried getting it to work in recovery and no joy. Flashed the latest CWM 5.0.1.0 and still nothing.
Then tried Royal Panache and the phone seems to see the comp, lets me pick what kind of connection i want to use but then nothing else happens on the comp. A
Any new tips?

did it show up on the panache rom then? when you say it didnt show up on the computer, it didnt pop up and it didnt show in the "computer" section where it shows all drives?
Yes exactly.on panache only, it Shows in the phone but its as if the comp then can't see it. Still works fine with the hub but nothing else, have tried different computers, ROMs, cords, recovery images. The only way it works is through the hub. THIS MAKES NO SENSE.......could un rooting fix this? Could it maybe be the sdcard?

no dice mates, all the way back to stock and no difference. Like the panache ROM, the notification shows up, but it doesnt seem to make any real difference. Doesnt show on the comp or ps3 and so im on the phone with TMO now.

[SOLVED] USB connection not working (just charges, no mtp/adb/fastboot)

Hi,
The usb connection of my Nexus 4 suddenly stopped working.
On my pc, or even on different ones, device is not recognized: when plugged in the built-in usb ports the device does not even appear on windows device manager, while on a powered hub (the one inside my lcd display) it appears as an "Unknown device".
The hardware id itself is shown as "USB/UNKNOWN", in this case.
This happens both when the Nexus is in normal mode, or in recovery mode.
In Fastboot mode the phone does not show at all in device list, wherever I plug it in.
I tried to remove /reinstall all the drivers, rebooting both pc and phone, using different cables.
The phone, btw, charges correctly, even when plugged in the built-in ports and works perfectly
I'm on stock 4.2.2 unlocked, rooted + franco kernel M3.
I tried to revert to stock firmware, stock kernel, tried to do a factory reset, with no success.
What can I try more before a RMA?
EDIT: I solved it!!!
This is what I have done, so far: Downloaded 4.3 odexed/rooted update zip from development section, radio and bootloader (link), and applied the update via twrp.
Rebooted, the update was successful, but usb was still no-go.
Rebooted a couple of time after restoring apps using Titanium, still no usb.
So I just switched off my phone, connected to the charger (not the original one, a normal, bulk, 2€ usb charger), and left the phone there for 10 minutes or so.
Then I switched it on, unplugged from charger, plugged to usb and BANG usb and adb are now working.
It looks to me like some setting of the usb status (maybe fast charge???) where messing up the connection.
I tested the phone with every single port on my pc, and now it just works.
Still, I did not update the bootloader, I believe I'll do this later, but it should have no side effect at all.
What cable are you using and have you tried changing MTP to PTP in the Computer USB Settings on the Storage settings in the Settings on your device?
If that does not help then you will have to try an other USB cable.

Nothing. It worked until Friday, I believe.
Then I decided to switch to 4.3, downloaded the update zip from xda to my pc, and when I connected the Nexus in order to put the zip on its storage, it wasn't working anymore.
No hits, no bumps, nothing.
from what you said it seems that you have tried everything possible pc-side, except trying the same things on another os (you should if you have a secondary system)
IMO, something is broken in the phone's usb port, maybe the data pin is screwed up and it wont let your pc recognize the phone, but i'm no expert with circuits

Yeah, it could be possible that the device triggered Fast Charge but the kernel does not support it which could be causing the issue.
