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.
Sent From My Command Center... (aka basement)

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

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

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.

this can be pc related thing... have another pc in family ? or friend's house, go and try to connect your ns.

could also be a dead usb cable.. try another cable?

Did you enable fast charge? If so disable it and it will work. Disable it, then plug in again

Ahaa I didnt read that.. maybe its the usb port of the computer also, happens a lot when im busy with my laptop. also the cable as you say.

Weird my phone is going through the same thing after flashing AOKP build 31, tried several USB cables and computers..
Thought my phone broke..
I never have enabled fast charge..
Wonder what could be the issue?
I also flashed back to stock 2.3.3 but still can't mount USB.

Ok good news and weird finding. Accidentally hit fast charge switching tabs in ns tools. I ended up in the same boat as you guys. I opened ns tools and toggled it back on. Plugged USB and it worked. problem is it was showing as on so I toggled off reconnected and it gave me the mount USB and adb prompts. Scary part is it persist for you guys on a stock flash. That's not good. Luckily mines back if you hit the button toggle it again if you didn't yet don't! !

I actually tried flashing a fastcharge enabled kernel yesterday, toggled on and off to see but to no luck..sucks.

Update..
Got it fixed, what i did was flash AOKP build 31 again and flash my favorite kernel (Trinity) booted the OS and in Rom control/start up tweaks and enable SD boost..then pull battery...
Boot the phone up and connect to CPU and it worked.
I knew it wasn't the cable because i tried with 5 other cables..

At least in my case it wasn't that, i keep my phone clean (air duster), when i had my issue i cleaned it again just in case and it would persist...
It must of been i toggled fast charge by mistake and reflashed another kernel without ticking it off..that's the only thing i could think of..

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.

accessing files with cracked screen

A few weeks ago I rooted my ATT 800o phone, and even attempted to install TWRP. It gave me a compatibility error with 800o so forgot about TWRP. A week ago, the phone fell and the screen cracked, rendering the phone useless. It works perfectly fine, but I cannot enter the pin code since the digitazer is probably broken.
I tried LG PC suite and LG OPS or OTS (I forgot), and it doesnt see any USB device connected. I believe I left the phone in JUST CHARGE USB mode.
I need to access some files on the internal SD card, so I ask for suggestions on what to try next.
Assuming I can get it in download mode, which I should be able to, should I flash the stock LG firmware (800d) and then try to get into it that way? Will that wipe the files of the sd card (pics, application data, etc)?

I had the same problem, but I manage to use LG on screen app. But never mind, I sent my phone to LG, of course I paid for broken screen (now I have ballistics case, I hope it will be enough for future impacts), But I include a note with the phone and wrote that LG will only replace screen but not delete any data or reinstall soft, and they did I revived my phone in the same state as I send them, but screen was new of course

an OTG cable is a USB cable witch plugs in your phone but has a female end on it to allow you use things like a keyboard mouse USB drive controller etc.

@ clapper66, I don't understand how otg cable can help in his case.
@ OP, if you're in luck which OnScreen Phone feature has been ON as well as wireless, you then can use OSP with wireless mode.
Other than that, I don't know any way to mimic your phone on another display.
Worst case, send out to repair.

His screen is not broken the digitizer is cracked so the screen works but does not recognize touch. So of he uses an otg cable with a mouse then he can go under setting then go to PC connection then select MTP mode so that when he connects a USB Cale that's plugged into his PC it will show all the internal storage of his phone and get all his files off that he needs.

Your suggestion is sneaky, underhanded and mischevious, and i like it.

Well I know you can buy them online that's where I got mine, but I would check at some electronics store like RadioShack or bestbuy and maybe wall mart I think there like $5 to $10 or even go to your carrier. I ordered one of amazon for like $2 but it took like 2 weeks to arrive because it came from China.

Thank you for the idea of the cable, but I want to try something first. I want to flash it clean so as to remove the exchange pin and hopefully get into it that way. I want to possibly sell the phone, so I have to wipe it anyway. If I don't recover the files, not a big deal (i hope...).
My thinking is...flash it back to stock clean, and see if I can change the USB connection parameters enough to connect. Then I can recover my files, and then maybe I can sell it. It is presently rooted without recovery. How do I flash it back to stock?
