Big problem with Epic 4G! New UPDATE I/O device error.

This is when I put my phone into mass storage.
My phone is taking forever to be recognized by my Windows 7 computer, my laptop recognizes it right away, I am using my front USB ports and have tried the back one even. Also, I have installed drivers and un-installed them, I have also done everything under the sun to try and get it to sync better. But alas it takes a while for my desktop to recognize that I have put my phone into mass storage. It is really bugging me, I am also using the stock cable that came with the phone and have even installed the official drivers. But to no avail.

My windows 7 laptop recognizes it fine

I am not blaming the phone at all. I am just trying to understand why this phone doesn't mount and my Hero did fine and does fine on the same port. How can I not say maybe its the phone...

Lol well maybe its the usb like I was saying. Or maybe it just doesn't like the micro usb??

Very very possible my good sir. I will keep trying different ports!
EDIIITTT AND UPDATE!
I AM GETTING AN I/O device error.

Try reformatting the card... Use a card reader to pull your data off first..
You could also have a defect on your device, but I'd test it in a different computer before concluding its the phone..

It is definatetly not a device defect for I have a samsung laptop with Windows 7 home premium 64 bit and it recognizes right away. Also, I find that if I enable mass storage the computer reads it (my desktop) but it just takes a while to. I will jsut have to be patient I guess. lol

I'm having the same problem...I've tried both sets of drivers.

Very few defects exist across ALL the epic phones.. I was suggesting it could be a defect with that specific phone, but that conclusion should only be reached after further testing..

I had trouble with my Win 7 64bit laptop when I first tried to connect it. I switched to the usb port on the other side of the lappie and it recognized instantly. There seems to be a bug in Win 7 and how it recognizes the Epic on certain ports. My Blackberry worked fine in all ports. I did install the 64 bit drivers and still had problems with that port.

Phone isn't recognized in download mode on computer

I'm sure this has already been posted but couldn't find it. But I was trying to flash one of the roms that were posted in here with odin3 and when I put the phone in download mode and Hooke it up to the computer I get either device not recognized or device.malfunctioning but mass storage works no problem. I use the cable that came with the phone and used every USB port on the computer. Any suggestions?

Have you installed Samsung Galaxy S drivers?

I had that problem when trying to flash EB13.
From what others have said here (and my personal experiences with trying to flash EB13) the cable the Epic comes with is crap.
When using another cable, I had much more luck in getting Odin/Windows/Samsung Updater to see my phone.
YMMV though, but it worked for me.

I think you should re-install the drivers, and try a USB port on the back of the computer. Usually the ports on the front of the computer aren't the best for these things.

Reboot computer and reboot phone and try it again thats what worked for me in the past

Reinstall the Epic drivers from Samsung. Make sure to use the back ports on the back of your computer that are on the motherboard. These will provide better and cleaner power to your device, also cycle both the computer and the phone and don't plug in the device till after you have went into download mode. This should fix your problem.

Same thing happened to me. I tried using the micro USB cable from my wifes Blackberry. Works great now. Samsung's cables suck

I've installed uninstalled and installed the drivers again. Tried the USB ports in the front and back of the computer. I'll try and buy a new cable and see if that works.
Thanks for all the suggestions

I recently reformatted and couldn't get odin to work. I put my phone in debug mode and when I connected it windows ended up installing something else and everything worked after that.
Windows 7 64 bit with 64 bit samsung drivers.

Beats me then. Try a different computer.

Guys I've had this issue and tried everything you guys have and some. Look at the port directly on your phone. there are tiny little copper contacts on the tooth that can get bent.
You will have to use some tweezers to get it back down but look at this before buying a new usb cable as this was my issue

I checked that and didn't find anything bent in the USB port on the phone. Might try new cable and different computer when I have access to both

Okay stupid question. Doest it make a difference if the phone isn't fully charged? Haha if so then I'm stupid haha
Sent from my SPH-D700 using XDA App

I have done flashes with thirty to forty percent battery. I don't think odin checks your battery. I would caution against flashing with to low of a battery as your phone can die during a flash.

Curious... Did Odin work for you with the old cord? Or transferring files to the sd card? I ask because ADB doesn't work for me since upgrading from Win 7 32 to 64. I can get a little bit of logcat to run sometimes and it hangs but Odin works flawlessly. Have tried several cords (that also work on an old Windows XP machine I have) with no luck. I guess I could try a new cord but that doesn't make sense to me

That's one way of fixing it. I also had the same issue, resolved first removing all the drivers for the phone, updated chipset drivers, reboot, re-installed the phone drivers, reboot then plugging in the phone.
Just in case someone else has the same issue and doesn't want to re-install windows
System was a dell latitude e6410

Nexus 4 not detected on PC - Need to lock bootloader

So I've been having some SERIOUS issues with my battery and have requested an RMA. Last night after a ton of issues (and at one where I soft-bricked pretty badly) I managed to unroot + load stock 4.2.2. It was late at night, so I decided I would re-lock the bootloader later.
Fastforward to today, I enable usb-debugging mode, plug in the phone and Windows 7 gives me an error. It says there's an issue. I go to device manager and it shows up with the yellow logo. I figure it's a driver issue so I uninstall drivers, and re-install naked drivers .72. Restart, plug it in and the same issue.
I go to a different computer and try it, same pop (this is Windows XP) saying device not recognized.
I also noticed my device no longer charges from the computer, when I plug it in it charges for a second, then stops.
How do I lock the bootloader if I cannot connect my Nexus 4 to the computer?? I tried going to bootloader and connecting the device, but nothing happens at all there. SOMEONE HELP!
EDIT: Here's the error message in Windows under the device manager: "windows has stopped this device because it has reported problems. (code 43)". Getting panicked now.

Search for BootUnlocker in the play store. Never tried it myself but by the reviews it seems to work. Good luck.
Edit: just saw that you have to be rooted. Sorry.

Yep saw that one too.
I'm pretty much stuck. There's literally nothing I can do except hope it somehow magically works later on...
Would Google accept the phone as under warranty if the bootloader is unlocked? The battery is SHOT, like it drains 1% every min while under use + like forever to charge. My hope is that the thing never boots when they get it so they can't actually see that it's unlocked.

Try using a different usb cord and I'm not sure if Google will accept it.

Have already tried using 2 different cords. I'm going to try out another computer tomorrow that's brand new and see if it works there. Will also try charging fully but I don't see how that would affect it.
Still leaning towards them not being able to turn it on as a pass. That's the best possible case scenario for me.

I had same issue but try to update drivers of or PC
And install an app on or n4 called sdscan it will fix this issue

Tried it, doesn't work. Also, the issue isn't with the SD card since it mounts just fine on the phone itself. Issue comes up only when connected to a PC.
It doesn't even charge from the PC USB port.

My phone its not pushing drivers to computer.

Does any body knows why my phone wont push drivers to my computer? It just does it ones in a blue moon. Im on Icerom deodex, i think, because it was unlock which broke the usb drivers command.. i try different roms, port, and usb cable i event reset my computer and install lg divers but it will still not work. The computer doesn't even make a connection sound, and my phone say its charging.

mine's been doing this for a month, :/
my buddy's also has this problem. He's on Malladus and I'm on GreenDevil's unofficial CM 11.
We're both on VS980
I've been using Airdroid to transfer ROMS to my phone. https://play.google.com/store/apps/details?id=com.sand.airdroid
I have several different drivers, on my Win 7 laptop and Win 8 desktop and nothing has worked. I've tried different cables too. it's also not recognized in ADB at all ever.

I would LOOVE an answer to this. I have no idea what is happening. It's baffling.

OK so I think not sure(something got burn cause I left my phone charging in recovery mode and I felt to sleep and when I woke up in was burning hot?) So I'm wondering if that was the problem ? I'm freaking out cause I'm paying for insurance and I don't wanna brick my phone and not fix it. At least lg tool was able to reset the root counter so I can return it for a new one but now I can't! Now what ?
