[Q] Computer not recognizing phone in download mode

I rooted and installed Cognition 2.1.6 on my phone a few weeks ago and want to change to Cognition 3.04. When attempting to flash back to stock via Odin, my computer will not recognize the phone in download mode. (I'm using AIO Toolbox and running the debug check.) The PC fully recognizes the phone until I'm in download mode. I get an error "The device has malfunctioned" and the device manager shows an unknown device. I uninstalled and reinstalled the 32-bit drivers and the same issue occurred. I've tried both Odin 1 click and Odin 3 click and neither recognizes my phone, although I doubt it matters which version of Odin I'm trying. I've searched all over the forums and the closest thing I've found is pointing the device manager to the driver, but the Samsung USB driver directory has numerous .inf files and I have no idea which one to choose. Any help?
Other relevant info: Win XP SP3 32-bit, Captivate Build 1012...

havent heard good things about xp and aio toolbox... dev doesnt own xp, but does have vista and win7,
when pointing to a driver select the whole samsung folder and check the box that says "also search sub-folders" .... or wait not sure if xp has that option, its been 6 years... hope it does.
but if your drivers installed by the program, you shouldnt need to manual install.
try different usb cable (you didnt do that fast charge tinfoil thing did you?)
try different usb port,
try different operating system (torrent win7)

Hmm... The only issues with XP seemed to come with flashing a custom ROM step not the drivers. It seems like there is an issue with the drivers and/or usb ports. Have you tried connecting it to the USB ports near the back of the computer?

right, thats what i remembered.. are the drivers for all versions of windows? many users had drivers installed before the toolbox.

I had this problem when I tried last weekend without using AOI, so I doubt it's an issue with Toolbox. (I just pointed out that I used Toolbox to note that I definitely had debugging on. I tried to include as much relevant info as possible in the OP to avoid a lot of "have you tried this [basic function]" replies.) I tried multiple ports, too. I'll give it a go in the morning and see if Trusselo's "search folder" suggestion is a possibility...

I had this same problem and i searched for a fix for the three button method

It's not recognized when the phone is on? Seeing as you posted this topic using your phone I assume so lol. Have you tried restarting your computer?
You can download the correct drivers here.

Make sure you are using the oem usb cable. I had the same problem, changed cables and it worked

some cheap cables are for charging ... bt headsets and other stuff the data cables dont connect, its just for power.

You gotta make sure that your usb port is directly connected to your motherboard (usually back of your computer).

same usb port that has always worked. ive tried them all by now anyway

now i cant tell you how this helped but... i downloaded drivers to a different computer odin crashed while flashing reflashed and im 100% stock atm. Didnt do ANYTHING to my computer plugged it in and its working.

Duno what happened but I'm glad it worked out for you

I'm having the same problem with my captivate after flashing REDROM. It won't recognize it if I have USB debugging turned on...

i have a theory... were you on a GB or other i9000 based rom/kernel???

well, im still having a problem getting my computer to recognize the phone, i have to mess with it for a a while to get it to work. i really want to flash anew 2.3.3 rom but without being able to get everything working right im stuck in 2.1
is this a problem with my cord or the connection on my phone? or something weird with my phone after flashing it a lot. its currently back to odin stock, i have been trying to master clear it with no luck

continiuum miui and cyanogen mod are the only things ive tried to flash

well it looks like i'm done. my phone will not show up on my computer and its currently bricked, although i have no issue getting it to download mode i cant do anything with it. unless someone knows some magic, looks like im downgrading to my gf's 4 year old busted up BB

Guys, this problem while connecting to the PC body is stupidly charging .... Even in the download mode Odin does not see a body that could be? Connect other Cappy-all OK.

it must be a powered usb hub, on my buddies laptop only 1 out of 4 usb ports saw his phone.
if you can get into download mode you arent bricked.
try installing i9000 drivers, or try another computer.

I came up with this a while back. Could very well be the same issue.
Let me start by saying I'm flash happy, and everyone that knows me personally, tells me to just quit jacking with my phone. NOT A CHANCE! I'm on my 3rd Cappy and shouldn't have ever exchange it again. I only had to in the beginning, because I was a newbie and had not know enough, but to get me in trouble.
I presume that this should work on all Windows OS's. I personally am running Vista Enterprise x86.
My symptoms:
Plug in phone to the usb and it there was about a 15% chance off being able to mount to usb, and Windows recognizing as a mass storage device. I tried un-installing drivers and re-installing and it would work some of the time, until the point came when parts of the driver install would fail. Then to the point when it was just completely unrecognizable. I thought I had it fixed because it seemed intermittent. In the middle of flashing to stock, something interrupted communication between the pc and my phone. Restarted the phone and attempted the flash again. Got a little farther and froze again. I had to use another pc that I had never connected my phone to before and I was able to use my jig to trigger download mode, because no buttons combinations would allow it into download mode.
This got me thinking that it was specific to my pc and not my cable or my phone.
My resolution:
I went straight to the registry and went to find. I deleted every entry that came up for "i897" and "i9000" excluding what was listed in the system volume information, as I didn't have permissions to remove any keys. I didn't keep count, but I probably deleted 300-400 registry keys that pointed to my phone. It seems as if with each developers rom that I had flashed, there was an entry for a different device. Don't quote me on that, because it is just my personal consensus. I also un-installed the samsung drivers, the unknown device driver, kies software, and anything associated with samsung. I noticed that next to all of the i9000 instances, the hex key for me started with 1000ee. So I also searched for the first part of that key trying to ensure that all instances of the device. Lastly, I deleted the samsung folder from program files.
I installed the samsung drivers package commonly listed in all of the other threads for x86 operating systems. I plugged in my phone and watched as each and every driver installed successfully. Keep in mind different drivers are installed depending on if you have usb debugging on/off, and the options for if the preferences on you phone are set to media, storage, or kies. I have multiple usb ports, however testing has shown me that, for me and my setup, I can plug into the port that I used when installing the drivers the final time, I am able to connect consistently. Earlier today, I tried to plug into a different usb port and it was an unknown device. I am led to believe, this is because I didn't un-install the unknown device on this particular port.
If you intend to work in the registry, please remember to always back it up first. You can always restore.
Hopefully my findings can help you as they did me. Happy flashing and I would like to thank the community for the dedication to assisting each other and the developers, for making flashing, better than crack cocaine. Flashing rom's doesn't make you twitch near as much as a crackhead.

Well since you can't use your phone you should sell it to me

[Q] Galaxy Tab Issue

Not sure when it began but I am unable to connect my tab to any pc. I have tried 4 different ones. It just gives me the error message "usb device not recognized". I have the custom rom from overcome(the latest one) installed. I put the tab in download mode and the same issue remains. I turned on/off usb debugging and it still doesnt work. I even tried the *#7284#. That did not help either. Please help.

Hi..firstly, welcome to XDA Samsung Tablet Forum. I see you already register since Nov 10 but your post so far is only 2 post. So I'm consider you are still newbie (same like me
Anyway, back to your question.
Have you go to samsung webpage and download the kies?
http://www.samsung.com/my/support/d...WDXME&prd_mdl_name=GT-P1000&srchword=GT-P1000
Do that first, after install it, go to >>Tools>>Install driver. Click it.
make sure your tab is connected to your PC via USB.
After you click the install driver, kies will download the driver for you and it will automatically detect your USB tab.
please try.

Is your pc windows xp or 7? W7 doesnt need any drivers installed, but W xp needs drivers.

Sounds like a fault with windows. Try running updates or use a registry cleaner/fixer see if that helps.
CCleaner has one.
[EDIT] Ah I misread, looks like you have tried other systems with same issue. Not sure then.

I'm assuming you're not using the same cable with all of them, otherwise you'd want to try a different cable. If you've tried the different cables between the different devices and still the same issue, you might roll one of them back to stock and see if that fixes the issue or not. It's possible you have bad usb ports, but more than likely it's a software issue on the tab.

They all are windows xp computers. It was working fine up until a few days ago. Then it just stopped working. Im trying to flash back to stock rom just incase some software went haywire but I can't bec odin doesn't recognize my tab

Have you tried a different USB port?
I had the same problem with Odin/Kies. Updated Kies to latest version and reinstalled drivers and works now

How about the usb cable? Possibility is high due to cable itself. Since you using the same cable with all PC. You should try to change it.

Bad cable or bad tab. Borrow a cable to eliminate that.

Not sure, When i was reading instruction for how to update with overcome rom it said that if Odin doesnt recognise the tab try a different USB port.

[Q] computer can't see Galaxy S

my samsung galaxy s is not recognized by my computer no matter what i do!
don't know why, i've done some research, no results.
i've installed Kies, which i assume already installs the drivers, but when i connect, the computer shows no sign of connection (it says that i need to update drivers in device manager??) i tried different USB ports, toggled USB debugging on/off, NOTHING WORKS
the reason i want my computer to recognize the galaxy is because i want to update it to android 2.3.5 via odin. but when i enter download mode, the computer doesn't recognize it. when i'm in the system, the computer STILL doesn't recognize it...???
please somebody help, it's rooted, running a different MIUI version (not the ones in xda dev section), i'm not sure where i got it from, but it's called an ENG_MIUI?

CM7 (and subsequently MIUI) is built from the Nexus S source code, so find the proprer drivers for it. "CM7 drivers" should be a sufficient google search. Also, Kies sometimes interferes while using the other drivers. If you run into any problems, uninstall Kies.

To get your phone recognized you need nexus s drivers. But that won't help you get it recognized by kies.
You need stock firmware on your phone to get it updated through kies.

I have same problem previously. But it solved after I do this: while Kies open, select Tools then press Install driver.

thanks guys, but how would i go about doing that? the directions i found don't make any sense?

Just to clarify, this won't help you. Samsung uses Samsung drivers. Since you do not currently have Samsung firmware on your phone, this won't do you any good. As previously stated by two very informative posters, you will need the Nexus S drivers to recognize your phone.
And, also as previously stated by just an absolutely wonderfully helpful poster, if you do a simple google search you'll find exactly what you need. Try either Nexus S Driver, CM7 Driver, Nexus S CM7 Driver, or really anything else similar. You could also check the CM7 Wiki, as I'm sure there would be a link for them there. And finally, if you simply search XDA Developers, I'm sure you'd find plenty of posts with what you need.
Hopefully that helps.

thanks
now my computer can see it when it's in android, but why does it STILL not see my Galaxy S in download mode???
do i need another set of drivers? (it said driver not found)
BTW THANKS GUYS!!! sorry if i'm being annoying

hello??
anybody??

Well did you install the Nexus S drivers yet?

Well, it seems to be a driver issue!
Try these (32-bit windows) but make sure that you are having a fresh win7 installed just in any case that your reg got corrupted with drivers (Ime ).
Still not working,then try on another pc..!

Well, CM7 drivers won't help SGS to get recognized on PC on DLD mode, you need another set of drivers and not those Nexus S's. I had the above ones installed on my PC (Google's your Best friend ) .

I had to install the drivers manually,
Right click on computer, click manage -> device something -> find your device in the list, select to update driver, search manually and enter the path to your android sdk and search.
Worked like a charm to me

hi
i had same problem, but computer recognize the device as "unknown device"
in all modes, developed, storage etc...
i am close to think thats is problem of internal usb driver of the rom
want to downgrade from de device, whitout usb, but i dont know how do it, because i am not root, and its no possible in 2.3.4 whituot usb.
thanks

I had a lot of similar issues with my I9000, too.
Tried everything on ROM and driver side also on different computers.
Finally it turned out that my Micro USB connector was corroded.
I have around 30 people in our company that have the same phone, and 5 of them had similar issues. I guess it's a common problem with this device.
I took a toothpick and cleaned the contact of the connector by sliding it up and down for a couple of million times. This also did the trick for my colleagues.
I think it's at least worth to try it.
Good luck

i try to clean the contact, but still cant connect to the computer.
I wonder if a method of degrading the system with a signed rom from the recovery, without using the USB cable or ODIN.

i have a same problem. Any new solution?

Rooting without USB possible?

Hello guys,
I have now tried for the last 8 hours to connect my phone via USB to my computer without any success.
I have read many threads concerning this problem but by now I just assume that my USB port is partly broken as I have tried all the solutions and none worked for me.
I can still charge the phone but windows isn't even showing that a device has been connected. Twice of probably thirty times windows showed me that an unknown device has been connected for a couple of seconds and then the phone isn't connected anymore.
I would like to root my phone and would like to know if there is a possible way to do it. Some say it's possible (depending on the Firmware already installed), some say it isn't.
My i9000 phone has:
Firmware 2.2
Kernel 2.6.32.9
[email protected]#1
Build Number Froyo.XWJPA
I hope you guys can help me, I am getting desperate...

Try this : http://www.unlockroot.com/
Here is the drivers : http://drivers.softpedia.com/get/MOBILES/Samsung/Samsung-Galaxy-S-USB-Driver-for-Windows-x64.shtml

Hey guy,
did you install Kies on your Computer? Your PC need the latest USB Samsung drivers. Note that you couldn't install Samsung drivers for newer devices like the Galaxy 9000 on Windows 2000 or older. You also have to look for the right drivers for your system. Maybe you did install x86 driver on 64 bit system or x64 drivers on 32 bit system.
Driver solution:
Go to settings, system and look for the hardware manager or simply check the "windows brenchmark settings" (included in vista and win7).
Try to follow that instruction: http://forum.xda-developers.com/showthread.php?t=1542633
Note:
If you have a working USB connection, you should search for flashing instructions because flashing is always on your own risk! It isn't hard to learn but you have to know which risks are there. Don't be scared by faults they can be undone (mostly).
Flashing:
First you should upgrade your phone to an early Gingerbread (3.2) build. Just search for "Gingerbread Stock Rom" or use "Darky's Resurrection" package. You'll find them here on XDA or in the world wide web
If you get trouble you'll get support here but first you should read about flashing and rooting.
best regards

As I told you I think that my USB port is damaged and hence I can't establish a usb connection to my phone.
I tried several drivers, Kies, different settings, simply everything which was already discussed.
My Galaxy will not even show up as an "unknown device" in my Windows 7 32bit (of course I used 32bit drivers).
Unlockroot requires me to connect the Galaxy via USB to the computer, so I can't use that.
Any other suggestions?

If your using a acer computer and you have never reinstalled window than it more than likely wont work. But you can google apps like z4root and universaland root i think thats what its called. Those apps i have rooted a few froyo devices with but z4 i have never seen work with the i9000 but try and see
