Phone isn't recognized in download mode on computer - Epic 4G General

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

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.

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??

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

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.

[Help] Nexus S 4G Won't mount Usb Storage.

In reality I really don't know where else to go I know that there is normally every time that you connect your phone it leads you straight into the Usb Storage now when I connect it. It just go straight into charging mode is there anything. Adb shell won't and I have to wipe it by tomorrow to send it our to Best buy! Help Please!
Is it rooted? If not wipe from the bootloader?

I had this problem. Here is how I fixed it. I deleted all Android phone and USB storage drivers from my computer. Then I plugged in the phone to USB. Then I quickly removed the USB from the phone while the computer was looking for drivers. Then everything worked fine again.

What data are you trying to backup? I would go into recovery, wipe data/cache, reflash the ROM, then test it.
You can backup apps/settings with titanium backup before you wipe.

I've tried absolutely everything in this thread. Lost USB connectivity completely on my phone. Doesn't matter what machine, what OS, or what cable, or what drivers are installed. I'm assuming it must be a hardware issue at this point. Doesn't even work in bootloader.
For those updating OTA to 2.3.6 via OTA and needing to re-root their phones, make sure you're not having this issue. Being stuck without root is a pain in the ass!

Good advice actually. Scrubbing it with a dry toothbrush + using a a brand new 3 inch USB cable made the sucker finally connect.
Must have been a combination of bad cables and poor USB port hygiene
Yep, had to take a knife, brush, and alcohol swabby to mine.

You should choose update driver in device manager and allow Windows Update to search for new drivers.
Could also be a bad cable. They are cheap crap. Get a Blackberry or Palm Pre cable.

I doubt the cable "went bad," more like "was a ****ty cable from the get-go." The stock cables are notorious for having connection issues, especially when using Odin or Heimdall.
Thought the cable was bad so i tried wifes evo w same cable and it connected instantly
Can the charging port go bad and only allow a charge and not a data transfer.
So im back to square one phone stopped connecting to pc since update to gingerbread
Any suggestions or insight on the subject
Plz no stupid grammatical comments or sum other dumb **** thnx

What type of cable is it I know lg ones don't work for samsung but will for the evo for some reason. Also it could be windows screwing with you. Is it showing it as an unknown device if so I know a workaround its not too difficult.

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

When you connect the phone to your computer, do you get an RSA security message on your phone allowing the computer to access your phone? I'm asking because I didn't notice the message on mine at first. Once I clicked yes, it was fine from that point forward.
