Try uninstall again.
Dl usb drivers but dont install. Save them to desktop
Plug in phone
Unknown device pops up, click on message. Click install custom drivers, navigate to where you saved uninstalled drivers are. Select
This has worked for some
CM7
Ok I uninstalled any versions of the drivers, when I plugged in my phone, the computer said unknown device as usual but it is automatically installing an "unknown device" driver. When I went to select the driver manually for it, it told me that there was no need to update and it didn't give me another option.
I should probably mention that originally, the computer recognized my internal sdcard when i mounted it. Now it isn't, and it won't recognize it in any mode.

what rom are you using now? does the driver you installed came from the stock eclair or froyo. I get the same message after flashing from stock to custom roms. I just plug my phone again and the pc automatically searches and installs driver from gt i900 driver. My old PC is running win xp with android sdk manager in it aside from the kies mini it has which already has the samsung drivers which supports stock roms.
definitely wrong drivers...If your computer recognize it in normal mode as in to mount internal sd card, but says unknown device in download mode than try to download USB drivers from somewhere else...
I have noticed this that drivers from samsung website doesnt support the download mode...I have faced this problem...mine would ask for gadget serial..so i use this drivers...http://drivers.softpedia.com/get/MOBILES/Samsung/Samsung-Galaxy-S-USB-Driver-for-Windows-x86.shtml
Hope this helps
I'm running perception 10.4. I've tried several different download sources, and it doesn't read when I mount the sd card anymore. On my windows 7 computer it worked no matter what rom I had, and I didn't have to change drivers at all. I'll try that link and see what happens
Still won't work...
This happens to me all the time when attempting to flash back to stock. What I do is just keep doing battery pulls and switching usb ports. Eventually, it works!

lol How long will that usually take until it works..
I've tried pulling the battery and switching ports at least 15 times.. nothing happens. windows installs an "unknown driver" automatically, and if I choose the galaxy s drivers for it, it says the driver isn't compatible for my device. It's not even recognizing it's a phone, or a mass storage device, or any other usb device it can be.
Unknown Device
Was this ever resolved? I have the same problem. Unknown Device in Download Mode. ADB works, PC recognizes phone in normal mode.
The phone shows up in Device Manager when in normal mode. If I use ADB to reboot download, the PC immediately drops the phone and displays unknown device in device manager.
Have tried complete uninstall/reinstall of drivers including regedit. NO JOY.
Running XP SP3. Any ideas?
after upgrading to gingerbread my pc thinks it is an i9000.
try those drivers.
i have no issues though.
Okay a little backstory:
I was on an early version of CM9 but as i am selling the phone i decided to put a more stable version of it on there and downloaded CM7 -stable.
I flashed this in CWM and it worked fine.
I gave it a quick test and noticed all the google apps were missing, most importantly the market. So i booted into recovery and realised i had forgotten to put the zip on the SD card.
I then went into mounts and mounted USB, nothing happened...
From that point onwards the phone would not talk to the PC. even if i booted up into the phone, it would just show it as charging. I could not find any options in the menus for USB options.
After some extensive reading, i tried a few things, none of them had worked. I found a post mentioning some kernels have issues with USB, so i downloaded the recommended one and flashed it in CWM.
After rebooting, CWM was now orange and not blue and the option to flash from external card has gone.
I have also done some digging and there is a good posibility that the kernal that i flashed was for the GT I9000 (which is the american one, right?)
So as it is at the moment:-
I can get into CWM.
I can get into download mode through the 3 button combo.
I can get into download mode using home made jig.
I can boot the phone, but it boot loops.
I can not get the phone to be detected on the pc.
Things i have checked:
Cable will connect other phones.
Tried different cable to be sure.
Phone used to be detected, but downloaded drivers through kies again to be sure.
Closed Kies using task manager.
Nothing is coming up in network connections in device manager when phone is connected.
I'm out of ideas now, so £10 PayPal donation for anyone that comes up with the solution to fix it
If i can get it detected, i can use Odin to flash what i want.
Sounds like a drivers problem. You may need the 'Google driver' developer.android.com/sdk/win-usb.html
When I had bootloops when I first installed CM9 I used heimdall to flash a the stock CM9 kernel. This gave me back CWM.
heimdall flash --kernel 'kernel.zip'
In the commandline.
Thanks for that,
I already had the Google USB drivers from when i installed the SDK to make some apps.
So i then gave Heimdall a try (Graphical Version), it seemed to suffer the same problem.
Reporting "Failed to detect compatible download-mode device."
I seem to remember the GUI saying I didn't have the correct drivers and it downloaded them for me.
The other thing worth a try is changing the USB port and reinstalling the correct drivers on that port.
I've not seen anything like that, it has not asked me for any drivers.
It's like the phone is not connected at all. nothing will detect it, i have even tried it on another PC.
Sorry, I'm not sure what you mean by installing on a port.
Well sometimes changing USB port will allow you to install new drivers. Although if you've tried it in another computer and it doesn't work then changing port may not help.
Does the phone appear in device manager when it's connected and in download mode?
Nope. Not coming up at all in the device manager. It didn't when it was booting fine. And it still doesn't in download mode. :-( I'm thinking the usb connector on the phone might be faulty.
But it was working up until trying to mount the USB in CWM

I don't suppose you have access to a Linux PC do you? Windows USB drivers are notoriously sucky. If you could plug it into a Linux PC and type 'lsusb' at a command line, that would at least show you that the device is really there.
I think I have a spare pc kicking around that I could use. I'll give it a go when I get home tonight.

Remove all the drivers completely from device manager for Samsung, then install fresh drivers and connect the cable when in download mode, hopefully it will recognize it
Are you sure the connector is clean? e.g. maybe there's dust in it.
I had that problem once, the connector was full of fabric fibers from some coat's pocket I had the phone in.
Suggestion 1 (Linux): I installed ubuntu, did not detected anything to even install any drivers. Detected my new phone fine.
Suggestion 2 (Uninstall drivers from device manager): I could not find any drivers named with the name Samsung in there.
Suggestion 3 (Clean port): I have some compressed air that i sprayed inside, it does look pretty clean and will continue to charge but still not connection on the pc.
To install the drivers for heimdall you have to run zdiag from inside the driver folder. Had to do this earlier on, the phone the other appeared as something other than Samsung composite usb or whatever it normally says
I tried this, and it displayed 9 devices after selecting show all. I seemed to recognise all of the items in the menu.
To be sure, I then disconnected the phone and re ran it to see if one of the items were missing, but it was the same number.
I too had problem with the usb connection on my i9000, and I was pretty sure my usb connector on the phone is somewhat damaged since it sometimes can only go to charging mode without being detected by my pc as a usb device. CWM instal is fine but ODIN can only detect the phone without able to flash the rom to the phone. The flashing will always stuck at the message "Setting Up Connection", I waited for 15 minutes and the flashing will eventually died. I retry the odin flash for 40 to 50 times and eventually the flashing will go through one time. Tried heidmall command line and the result is the same.
I have problem with Odin in the past. I bought a new laptop, running Win7 64 bit. Installed Samsung Kies to install the correct USB drivers for the phone. Then made sure that Kies wasn't running in the background. So tried using Odin. Odin was detecting the phone, but it was hanging at initialising connection. Odin was working fine on my old laptop running Win7 32bit. Long story short, I was having a few issues with my new laptop, reinstalled Win7 64bit, now Odin is working fine, have flashed the phone a few times using the new computer.
After flashing which kernel you started facing this problem?
Wipe ur phone,re-flash CM7(flash the nightly 181,it's completely stable),uninstall KIES,uninstall old usb drivers,install these usb drivers http://forum.xda-developers.com/showthread.php?t=961956 ,check that USB storage mode is set as Mass Storage and then connect your phone. Also try enabling/disabling USB debugging

The point at which i could no longer mount the USB was when i selected "mount usb" from CWM. I later installed a new kernal which downgraded my CWM, removing the install from external SD option.
So I cant flash a re-flash a rom unless i can it onto the phone which without the USB working is near impossible.

You can directly download the ROM on your internal sd using dolphin browser or opera mobile
I can't do that either as the phone is currently boot looping.

Hello to all,
I would like to install a custom ROM but unfortunately my phone doesn't want to enter in flash mode! Once switched off, I plug it to my computer while keeping vol down button pressed but instead of entering in flash mode, it displays the battery charging icon.
I hard reset the phone but the problem still remains. Any idea.
Thanks, have a nice day!
My guess is either the USB cable (did you use the OEM cable?) or the drivers (does windows recognize your phone?). Removing the SD card or first entering recovery were suggested earlier (http://forum.xda-developers.com/xperia-l/help/update-volume-connect-doesnt-t2613733). But more experiences Z3c owners may have better ideas...

Using flashtool:
Turn phone off completely.
Start flashtool, choose flashmode and choose which firmware you are going to use. Tick Exclude TA.. Click on flash.
It will start preparing the build and after a few seconds it will ask you to connect the phone.
Plug the phone in while holding volume down, as soon as flashtool starts doing something, you can let go.
If you don't know how to use flashtool then I urge caution, Sony's aren't like flashing a Samsung, it is actually possible to brick your phone with flashtool. There are lots of questions on 'how do I fix my phone?' in this Q&A thread from people who didn't read up on what they were doing.
Recommend you read bilboa1's great guide on what to do, starting with backing up your TA partition..
Thanks for your answers but I think the mini usb from my phone must be dead.
About Flashtool, I can't use it because I can't go into Flash mode! Moreover, my phone is not recognized by windows. I tried with several usb cables and computers when I plug it, I don't have any MTP or PTP choice, it can only charge..
On Windows 10, devices is not recognized and Window 7 see it as a 5880!
And I tried to remove SD and SIM cards..

If the USB lead was dead you wouldn't get the charging icon on your phone.
Have you installed the Sony drivers.
You also need to run exe in the Drivers folder within Flashtool, to make sure you have correct flashomde drivers available. Installing these drivers is very difficult in Windows 10 and it require restarting the machine in safe mode, and going into the advanced settings to disable driver signature checking, this how to video is for windows 8, but you'll get the idea
Have you installed ADB?
Sonys PC Companion should set you up with the correct connection to your PC
Have you tried other USB cables?

Yes, I've installed PC Companion, adb drivers but nothing appears when I use command "adb devices". I've also installed flashtools drivers but deactivating drivers signatures in Windows. But when I try to flash, flashtool ask me to turn my device in flash mode (switch off then volume down + power) but I can't do that.
I've tried several usb cables. Some are charging my devices, some are aren't but none of them allows me to data transfer!
I've also tried to force MTP or PTP usb transfer in developper option, it doesn't work more..

Do you have any warranty on your phone, you could be right that the usb socket is damaged somehow, but it's strange that you can still get a charge through it.
Your only chance at moving to a custom rom change is flashfire
This should let you flash a rom without recovery.
Edit: Flashmode is just holding down just - volume button, not volume+power
Obviously your chances of rescuing a failed install are going to almost zero without recovery and flashtool, so be very very careful about what you try and flash in flashfire. Read up completely that the rom you want to flash is going to work pushed on top of whatever you are running at the moment.
For anyone who might be interested, sometimes you have to try a USB 2.0 port or just a different port. I had the same problem while using a usb 3 port, switched to 2.0 worked like a charm.
Try to open the back of the phone and removing/unplugging the battery wait 5 seconds and then put it in again. Then try holding down the volume down button while you connect a usb cable.

sir i have sony e3 dual and wanted to flash a custom rom . i connected it to pc but after the original firmware was deleted i got to know that my phone volume down button isnt working. anyone please tell me how to put my phone in flashmode without pressing volume down button as it is not working
Hello guys,
as I wanted to delete unnecessary blow apps I think I deleted some important System app that is responsible for connecting to a PC. Now the S5 mini behaves as I it is connected to a battery charger when it is connected to a PC, there is no sign that it is recognized by the PC. I allready tried to Flash recovery with Odin but it isnt recognized by Odin too (in download mode). Am I doing something wrong? Can someone help me PLEASE get my phone working again and flash some custom ROM? Thanks in advance!!!
Try to install kies drivers for your smartphone and retry on odin. I think the only problem is the missing of the drivers
No, Kies is installed and it has no effect. Neither Kies nor the Computer recognize the phone, even on the phone theres no sign it is connected to the PC except the battery loading sign.
Try To find the drivers on google and install them. Do you have a custom recovery? If yes you can flash a custom rom
Download mode isn't related to kernel nor recovery, so unless you somehow wiped all phone's memory (all partitions) you'll still have download mode. So if you can enter Samsung's download mode and your computer doesn't recognize the phone it's one of them:
1. Bad cable, some USB cables only charge, no data connection;
2. Bad USB port on either phone or computer, try and different computer.
Good luck.
Hi all,
I have OP3T that just not recognized by my PC. I also have another OP3 that connects just fine to this PC. I tried dev menu and USB debug+ MTP, tried to wipe cache, install a new stock ROM downloaded from OP website, also installed the drivers in the PC.
device manager not shown anything when I connect the phone (no MTP device or Android device) and tried several cables and also another PC.
the phone was rooted until the last update (last December) and now I want to install custom ROM and I can't!
I think you want to fastboot flash a recovery?
What OS? Fastboot devices returns null?
yes, so I can install custom ROM eventually. my PC runs win 10 64X and right now my phone has stock android 8.0 (OOS).
what happens that when I connect my phone to the computer there is nothing going on- no now device in device manager and not a new driver pops, so I just can't flash recovery.
is there's an option to flash recovery without using the PC?

No generic MTP or Android device at all? On either PC, trying different ports (I know you said you tried multiple cables - which is good trouble shooting)? And no pop-up on the phone, allowing you to select MTP (move files, or whatever it says)?
If that I the case, I tend to think the USB port is damaged.

I've seen some folks package TWRP into a bootloader-flashable zip on other devices, but haven't seen anything like that on the 3T.
More importantly, I'd say it's very risky modding the phone with custom recovery and flashing a ROM, without having fastboot and adb tools available. You can get stuck in a real bad jam doing this, with tools to recover the device. I don't recommend it.
Yes I tried it all but there is no indication besides the device is charging while connected to the USB port.
OP support say that this might be the case, but I don't know if I want to replace it since my screen is cracked and it will brake it as soon as I open the phone
