I was updating the firmware on kies for my galaxy s and it got half way through and then said error and is no frozen on the downloading 'do not turn off' screen, I have taken out the battery and put it back in, and tried the hard reset, which leads me to a phone symbol, a computer symbol and an error symbol in the middle, help plzzzzzz
I had the same problem (except I didn't use Kies, I had the problem after the first OTA Update)
Here are the steps I did to get my device back in a usable state:
Keep in mind, this will revert your phone to a rather old (android 2.1) version of TouchWiz. You may want to see if there are newer ODIN files available.
Also, I take no responsibility if this does not work for you, or your phone explodes in the process. These are the steps I took, and they worked for me. Good Luck.
Download JFD tar
Open Odin, plug in your phone, then put it into download mode.
# reboot download
If you can't get that to work, try how i mention below (phone off, battery out, hold vol+ & vol-), or try searching these forums for "vibrant download mode" you will find other things that "work" for people
load the PIT file in appropriate area.
Click start, let it finish.
Now, pull your battery and unplug USB
bring the phone to download mode again
re-run ODIN as mentioned above
Don't give up if this doesn't work. If you get the device to boot, even if it is to the "Error Screen", there is a possibility of recovering.
You should experiment with rebooting via the various key combinations / battery pulls / USB plugged-in-ness below first. Sometimes the phone can be jolted out of the bad mode it's in by doing that. If the firmware was partially written though, you'll have to do Odin as Ryan suggests.
I basically agree with Ryan's answer, but I'd use at least Odin 1.5. Here's Odin 1.7, it includes the 512 PIT file.
For the GT-i9000 (international Galaxy S), get firmware from this XDA thread. You probably want the newest for your region (excluding Gingerbread, since it hasn't been officially released).
I also recommend checking re-partition in Odin. This will wipe 100% of your data, however.
I think the easiest way to get into Download Mode is through key combinations. For the i9000, just hold Power + VolDown + Home until the phone reboots, then let go of Power only; after a second you'll get to a yellow triangle with an Android in it. For the Vibrant, remove the battery, plug into USB, hold VolDown + VolUp, and insert the battery.
I discovered today that I cannot connect my PC with Samsung GT-I9000 any more: when I plug in the microUSB cable, nothing happens other than that the phone starts to charge. Earlier I got to see Connect to Kies or something like that.
Things I've tried so far:
-Switcing USB debugging on and off
-Trying different cable
-Trying reimaging PC to a known good state (where I previously would have found new hardware)
-Trying different computer
-Factory data reset
-Formatting internal SD card
-Entering download mode with mUSB jig (my phone has download and recovery modes disabled otherwise) and reconnecting mUSB cable. Then I saw the "USB Device Not Recognized. One of the USB devices attached to this computer has malfunctioned..." error on Windows (XP).
Is there anything else I could try before sending it to the long journey of Warrantyland?
I tried an app z4root which rooted the phone without the need of usb cable, then I could use Rom Manager to force the phone into Recovery Mode (remember my phone had the 3-button combo disabled). There I deleted-erased-formated everything I could and when I got back to normal mode and tried connecting again, Windows found new hardware and Kies recognized the phone. Just to be sure, I pulled the cable from computer, waited for 2 secs and then reconnected but, alas, nothing happenend again. I reimaged the PC and redid the z4root+Rom Manager+Recovery Mode wipe thing but nothing. Then I tried to reinsert microusb plug into phone under an angle and witnessed a successful connection. Kies offered updating firmare. I did not breathe on the phone and carefully clicked mouse to accept in hope that if this was a software error, new update would fix it. The update went fine but after the phone rebooted and I could confirm the firmware version from About, I still could not connect.
Then I used USB jig which I purchased from eBay to force the phone into download mode and tried to connect it with a PC once again. The PC froze at once (even the mouse cursor did not move). I tried pressing every conceiveable keyboard combination from Enter to Ctrl+Alt+Del and then disconnected the USB cable. As soon as I did that, everything started moving again on the screen. I could reproduce this behaviour for 5 times. On the sixth time, however, Windows found new hardware and started installing drivers but soon after that a balloon popped up saying "USB Device Not Recognized. One of the USB devices attached to this computer has malfunctioned [...]". Then I rebooted the phone and came back to the issue later.
I forced the download mode once again and plugged the USB cable in. Nothing happened. No frozing, no error.
Even though I have tried to wiggle the microusb plug in from every possible angle, it does not seem to have any effect. It just works when it wants to work. Charging works always, though.
I have followed the Exact steps from Link :
Samsung mobile MTP Device cannot be installed
Here are steps : (for Windows specific instructions):
for Windows specific instructions
Ensure phone is not connected to PC.
Uninstall KIES from PC. Reboot your PC and Reinstall KIES after that. Just for great measure... open KIES, go to Tools | Troubleshoot connection error. Follow instructions and wait for it to finish the troubleshooting procedure.
Tools | Troubleshoot connection error
Do not connect it to your PC just yet.
Hope it will help you..
I'd try uninstalling all your drivers/software for the phone, rebooting, reinstalling the official drivers from samsung.com/uk, and trying again. You could also just install the drivers on another computer that has never had the phone connected, to ensure it starts in a clean state. If that doesn't work, I would guess a trip to Warrantyland is required.
I had similar problems with mine - plugin on USB, it would charge but do nothing else. It wouldn't even recognise the phone was attached to install drivers.
After some internet searching, I was ready to give up... but I tried on a different USB port... and more importantly, used an old usb cable from my old phone. Suddenly all sprang into life! So my suggestion is to try a different cable, I think cheap cables are not all made equally.
Charging worked with either cable, butif the PC knows something is plugged in and istalls the drivers then this is not likely to be your problem, unless you have a dodgy connection in there somewhere.
I had a simular problem, it was caused by moisture getting into the terminals while using phone in the rain. terminals need to be cleaned or replaced
I will give here a solution which I found when I had a similar problem (note: this answer was already given in this question). It really took me some time to find this solution, and to be honest, I seem to be the only one with this problem/solution, but maybe it helps other:
-- my answer to a similar question on this site --
I had a similar problem when I still had my PALM synchronization software installed. For some reason or another, it used COMM port 4 for it's communication ( don't know why but it did ), and that conflicted ( probably behind the scenes ) with the communication with my Galaxy S.
Once I uninstalled the PALM synchronization software, the connection went fine.
So please check if on your pc some sort of other communication device is installed.
I tried everything too. But after a while, I had to install a fresh version of Windows 7 and to my surprise, Samsung Galaxy S connected with USB.
