Unable to see phone when in download mode

I'm trying to revert back to stock on my Epic. I previously flashed using Clockwork and wanted to try Odin this time around but when I put the phone into Download mode my computer doesn't recognize the device. I've tried multiple cables and USB ports including one on the board itself. I am using Windows 7x64 and have the 64 bit samsung drivers installed properly. If I do a battery pull and boot the phone normally the computer recognizes the phone no problem.
Any ideas?

I was having a similar issue with my MBpro, nothing would recognize my phone. Tried it on another comp and bingo. I think stuff is just finicky with USB ports. Lame-o.

Yea...this post made my brain hurt...and of course didn't change anything...but..thanks?

Here's another piece of info that may help nail down the problem...
Odin is able to see the phone if I boot into Clockwork recovery mode but because clockwork is up the phone can't receive a flash but Odin does see the phone with no problem. It just still won't see the phone when booted into download mode.

I use windows7 64 too. I encountered tons of problems when trying to flash my epic. first my computer doesn't recognize my phone in download mode. after i wipe out all the drivers and reinstall them. finally i get my computer recognize it under download mode, but Odin froze every time during the flash.
Finally, i tried on another desktop computer with windows XP. Everything went perfectly. So maybe you should try that too.

I cannot connect to my Epic in download mode on mac os x either.
I was trying to install a lag fix, and now all my phone will do when powering on is show switch between the normal Samsung screen, and another reading "Samgung GT I9000".
I can still boot into Clockwork Recovery. But OS X will not recognize my phone.
Either that, or Heimdall isn't recognizing it and won't let me flash.
Help! Any ideas?

I had the same problem, I couldn't connect it to 3 of my pc's. 2 xp's and one windows 7. Turned out the port on the phone it self was broken, had to take it sprint and get it replaced.

If OS X isn't recognising your phone it's likely your phone has the buggy secondary bootloader. Samsung corrected the bootloader for at least the GT-I9000 JPA firmware but I'm unsure if they have done so for other devices or firmware releases.
Unfortunately the only solution then is to use Windows or Linux. If you don't have access to a system running either of these OS then I recommend downloading a 64-bit release (assuming your PC has a 64-bit CPU) of Ubuntu, then you can download the Heimdall binaries from my website and use it to recover your phone.

i had an extremely similar issue as to what you are having. I have 3 win 7 machines and 1 xp, none worked. I went to a friends house he has 2 win 7s and an xp also didnt work. I did a general search and found all kinds of crap. One dude something about using his chicks blackberry usb cord and suddenly it worked on any and all of the machines it had previously not worked. so at the time im reading this on my chicks laptop which has a damn blackberry cord attached to it chargin her evo(go figure) ... anyway u didnt need the whole story but i have nothing to do right now.
Point is everyone says try different cords, i say try the damn blackberry cord if you happen to have one or a friend that has one.

Is it the hardware on the Macbook pro itself? or just the OS? in other words, If I were to partition my macbook with ubuntu would that work with heimdall? would it be able to recognize my phone while it's in download mode as opposed to OSX, which couldn't...?

In this particular instance Apple haven't done anything wrong at all, both their hardware and software is fine. The issue is that Samsung are distributing secondary bootloaders that aren't complaint with the USB specifications.
Whilst that is annoying, the good news for you is that you can simply install Linux (Ubuntu etc.) or Windows on your Macbook and you'll be able to flash just fine.

phone seems bricked

hi my mate has and s4 9505 and he wiped the hole phone like a noob and it wont enter recovery and in odin nothing will flash tried pit file and also stockrom it either gets stuck on setting up connection or stuck on pit mapping part tried adb devices command but its not picking up the devices the drivers will be on his comp as he has all ready flashed things via odin before on the s4 any ideas people cheers

Try that:
You can use this software to repair Your dead Samsung i9505 and similar (m919, i337, L720 etc)
Note, You need to install QHUSB Qualcomm drivers first.
After flashing with this software, You need to flash phone with official firmware and PIT file, otherwise phone will be dead again, and You'll need to repeat the process.
If You get errors reported by this software (command prompt window), You'll have to replace the eMMC chip first.​

Did you install the drivers for the phone?
Did u put phone in download mode and flash with odin?
If so, trying closing all kies process, changing usb port and run odin with admin. Flash pit file and stock firmware.

What odin version are u using? Are u sure you have properly installed kies or drivers? The latest kies version? Try disabling antivirus and installing latest kies.

tried with odin 1.85 3.04 and 3.07 and yea latest kies i uninstalled antivirus to be on safe side as i no it can conflict with odin and stuff

The problems you are having are purely driver issues. Try flashing the phone on another computer.

Let us know if it worked

Try a different data cable it worked for me
Sent from my GT-I9505 using xda premium

Well I've had some problems too today and there a couple of things you might want to try (I'm sure one of them will fix it):
- Pick a different USB port (preferably one in the back)
- Try a different USB cable (I used one from my Nexus 7, didn't work. Tried with the original S4 cable, worked)
- Uninstall Kies and the Samsung drivers from you control panel -> programs
- Download the Samsung USB Drivers again (google it) (do not install them yet)
- Download and install USB Deview (google it) and delete every driver of Samsung you come across in the list (just right click and click delete)
- Disable your internet access and reboot
- After rebooting install the Samsung Drivers (without an internet connection)
- Plug in your phone after you've installed the drivers and enable USB Debugging
- Reboot
- Enable your internet connection again
- Try to flash again in Odin (it should work now)
If this won't work, I don't know what will. A different USB port, cable, fresh/original drivers (not the ones Windows Update may try to install for you), etc is probably what you'll need to get it working.

thanks for every ones help we installed a fresh copy of windows 7 and installed every thing again and it worked fine defo must of been driver related :laugh:

Cheers now flash away like there's no tomorrow

[Q] USB device not recognized

I've flashed my i9505 many times. I can't remember exactly what I've done, but now the situation is very weird.
1. I can go into Download mode. But Odin doesn't recognise it. Kies doesn't recognise it either. The error message on the bottom right corner of the screen says "USB device not recognized. Your usb device has malfunctioned." I've tried re-install the USB driver, use the original USB cable, even tried it on another PC with no luck. I suspect the very low level USB driver in the phone has corrupted because possibly I flash something wrong in the past.
2. I can go into Recovery mode and flash new ROMs in zip format from there.
3. I can use my phone normally, e.g. make phone call, SMS, WiFi......My computer can recognize my phone as usual when I am in Android.
Any thoughts? Helps are appreciated.

Hello,
Uninstall any previous installed of Samsung USB drivers, clean your Windows registry through CCleaner (not needed but highly suggested) then download and install latest Samsung USB drivers
Now download mode will be recognized on PC
Inviato dal mio GT-I9505

There is an easier way. If you are using windows, go into control panel-> Devices-> Right Click on your phone-> there should be a Driver Details-> Go details I think it is-> Uninstall driver-> Have the box ticked-> Uninstall-> Unplug then replug the cable in and it should work.

I've tried to re-install the driver. I even tried to connect the phone to another PC where the driver had never been installed before. Nope.... it doesn't work. Actually, I've searched around in Google for long time. The most likely reason is the usb piece of Android code is corrupted. Well, maybe not android, it should be the lower layer of Linux. I previously installed dual boot system follow this link and I screw it up when I tried to upgrade the primary OS:

You said that in Android USB connection works.
The download mode depends on bootloader, that can't be touched in any way by Android, even you can't touch the bootloader.
It's also write-protected, you can only upgrade it through Odin or through an official OTA update, when flashed you can't downgrade and can't write on its partition if not through JTAG

Please help, s4 sgh i337m brick!!!

Hi there !!!,windows doesn't recognize my s4 i337m in download mode (code 29), when i was flashing (stock canada 5.0.2) my cousin unplugged the cable by mistake, now i can go into download mode but widows 7 doesnt recognize anymore (tried different pcs and cables , the same), did it damage the usb port? or is hardbricked?? what can i do??? please help!!

I'm no expert on this, but you can try taking out battery. Hold power button to discharge hardware and put battery back in and see if it works. You can also try factory reset & wipe cache from recovery (Vol Up + Home + Power) and try again.
Your phone at least goes to Download mode so that's good sign I guess. You're using ODIN to flash 5.0.2, right?
Wait more experienced person to answer, though.

Thanks bro, but i did what u said and it's still not working, the problem here is that windows does not recognize my s4 (usb port: unknown device, code 29) , yes i'm using odin to flash, but i can't flash until my device be recognized, that's why i need to know if my device's usb port is damaged?

It looks like the PC does recognize something is connected; it just doesn't know what the device is. This makes me think USB port is fine otherwise PC wouldn't recognize anything AT ALL. Does the phone still charge?
You can try the 3 methods here. I know it says for Code 28, but it will reinstall drivers for usb ports. Restart and see if phone is detected.
If it's still not detected, remove Samsung drivers, Kies, or anything related to Samsung phone. Restart and install Samsung USB drivers again. Restart again and see if phone is detected.

bro i'm afraid it did not work, perhaps replacing usb port on my device? or the whole flex?
aditional data: my nephew unplugged the usb cable by mistake while i was flashing canada stock 5.0.2 , obviously odin "failed" , but after that , windows 7 does not recognize my device anymore. i can still go into download mode.

Well, I'm stumped too now, man. You can try the driver thing I said on another computer. I don't know any other things you can try.
If you can charge your phone, your usb port probably works fine. The firmware got corrupted, causing this problem most likely.

solved!!

PC won't recognize Note 4

Have a note 4 on a custom rom- android kitkat. Was working fine, until i wiped data/cache a few times in TWRP recovery to do a clean install of the rom. Phone restarted without an OS, and then i couldn't get pass the boot logo screen. Couldn't flash any rom in recovery. So i did a restore thru TWRP from a backup. So now the phone boots, but it pc won't recognize it. Everytime i plug it, I get "One of the USB devices attached to your computer has malfunctioned, and Windows does not recognize it". Under device manager, I get "Unknown USB Device (device descriptor request failed)".
Things I have tried:
-Uninstalled usb drivers and let windows reinstall,
-at least 5 different usb cables
-at least 3 different Samsung oem usb cables
-other usb ports on the PC
-3 different pc (all with same- so im guessing its a problem with the phone)
-physically tried to push up the usb port on the phone- bad connection (someone recommended on google search)
- even when as far to reinstall windows OS
-*#0808# and set it to AP, MTP + ADB
-yes usb debugging is enabled
-download mode (odin does not see the phone, so cannot flash stock/custom rom
-diferent versions of odin
-different version of Samsung usb drivers
-have other samsung phones (note 5, and s6) and windows recognize those.
-phone does charge thru usb
need to get phone working again

Download stock rom from sammobile and flash it via odin.
Or else, flash the cf auto root file via odin, this reset all partitions.

Honestly man search my username ziggsta2 I had the same issue I had to buy another note 4 and even this used phone I got off eBay has the same problem when I wiggled the micro USB cord up and down I got it to connect, I don't suggest you doing this, but what might work is taking a very small piece of plastic and cleaning out your USB port on your phone, I believe these ports go bad after awhile as I have encountered this twice on two separate devices maybe you have a different issue but theres my two cents

i have tried. at this point i think it's hardware failure with the usb port. Stupid buying those cheap usb cables probably damaged the port because it seems to require a little more force than samsung cable. Planning ordering one and replacing. hopefully i don't do more damage. Had this phone for a long time and miss flashing roms on it.

i have still not fixed this problem....lol. had a new phone and been in drawer. did replace the usb port but it wasn't the problem. would like some solutions if anyone can help.
