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.

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 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.

[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.

If it's just for wiping why don't u do a format USB?

Oh I guess u wanna backup too... if u have wifi just connect via wifi and copy files... u can access ur comp from es file explorer on wifi

Wow I had this same problem about a week and a half ago. I never did find a solution. I tried multiple computers. I couldnt even unroot it because the computer did not detect it even in fastboot mode. I ended up sending it back to samsung to be repaired.

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.

Fixed mine with some serious cleaning of the USB port. I also tried buying a new cable, downloading drivers, etc. in the end, it was just a bad connection.

I've tried many cables, almost positive mine is a pure driver issue.

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!

Clean your USB port on your nexus! Clean it well.

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.

Ever since upgrade phone not recognized by pc

Is there sum driver not in the new software thats making my pc not recognize my phone anymore

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.

+1 for this. Also, even if your phone is set to PDA, select Modem and then select PDA again. That's what I had to do with my gf's phone to get it to work

USB charging/transfer not working

I'm not sure if it is because I upgraded to CM10.1 or because I had my phone plugged into a charger all night that didn't even charge the phone, but my USB port won't connect to my computer anymore. When I connect it, it says the device malfunctioned. What could be wrong? I feel like it's because the other charger messed it up.

no usb host!!!

I have a nexus 7 WiFi 16 gig refurbished from wallmart. Using for a car install, tried 3 different otg cables confirmed working on n7 2013 and made my own cable with external power and no go. Host mode will not trigger. No mouse, USB ,SD........ I get no notification that host mode is entered. Tried USB ROM, vanir, cm11, bs harmony, stock, every kernel. Still get nothing. Any ideas? Have power and volume soldered to some momentary switches. Any ideas I was thinking of trying to trigger host by shorting the pins on the tablet itself! Bad idea? All connections in the tablet look good.I am at a loss. Any suggestions are appreciated!!

Download stickmount.

What you are looking for is a kernel that provides simultaneous otg/host mode charging. Unfortunately, if you are running a rom newer than 4.2.2, you cant get it. All kernels that gave this capability were based on the work by Timur. He left that scene and never brought the hack to 4.3 +. If you install a 4.2.2 rom, you can still do it. If you google "Timur kernel" it will take you to his rootzwiki thread. He has a standalone kernel, or an entire rom dedicated to your very situation. Most people on the thread are car install users. Tons of great info there.
To the reply above me, the op is referring to being able to mount otg and charge at the same time, so stickmount would do no good.

Isn't this a stock feature? My N7 in stock 4.4.2 has no OTG problems whatsoever, and provides energy without problrms.

No, not a stock feature. Exactly how are you charging and mounting otg simultaneously, cable wise?

I use a generic OTG cable i got for like 5 bucks (it doesn't supply any kind of power). Mouse, gamepad and keyboards works as soon as i connect them. For drives and SD cards, i use Nexus Media Importer. All in stock ROM and kernel (4.4.2), without using root.

The op is referring to charging the N7, and connecting otg devices at the same time. The reason his otg is not working is because he connected the charging circuit first, which blocks host mode (otg functionality) from registering. The same happens if otg is hooked first, charging will not occur. It takes a kernel with those certain abilities to use otg and charge the n7 at the same time (host mode charging). Likewise, it takes a special cord, which has either 2 male usb and one female, or 1 micro usb, 1 male usb, and 1 female usb. Everything you need to know about this is here http://mehrvarz.github.io/usb-host-mode-power-management-nexus7/

tried it all
I have tried usb rom and stick mount,and nexus medis importer ect...... my problem is no usb host at all. not even a usb mouse. i have tried diffrent roms and kernels. i think maybe a hardware problem. i made my own usb host cable it works with my n7 2013 note 3 , but not my 2012 n7. nothing does. i also bought a few cables from amazon, no go. the tablet doesnt enter host mode. i tried usb diagostic app from chainfire. support is the for host in the kenels but host mode will not trigger.. just tring to see if anyone had similar issue and found a fix.. thanks for the suggestions.. kang-aroo kernel has timurs patches synced for 4.4.2 so does bricked and m kernel. OTG and charging IS NOT my issue, its no host at all. tablet will not recognize anything i plug in with external power or without....

As i thought the tablet was defective,recieved my new one no problems with usb host......

Awesome, glad you got it replaced. I use usb host mode charging, so I know how valuable it is. But, I am glad you posted your issue, because I was unaware of the existance of the kang-aroo kernel till you mentioned it. Running it on all 4 roms on my N7, and really happy with it.

Kangaroo is a great kernel , try oxydo has the same features but it also has doubletap2wake and s2w it's not enabled by default but trickster mod will turn it on or by editing a few files in the sys folder.In the kangaroo thread there is a manager app like USB rom has for a car install. Works on both kernels. Are you using multirom. I haven't tried it yet. Any issues?

Been using multirom since it was released over a year ago, and never had an issue. I cant imagine my N7 without it.
