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 tried to upgrade my firmware on my Samsung Galaxy S using Kies
The Firmware upgrade appears to have gotten stuck.
Upgradeing firmware... Do not disconnect a mobile device from the PC during upgrade process
Progress Bar has "Upgrade is in progress.." and is stack at about 1/3
The phone screen shows a green triangle with Downloading... below it and "Do not turn off Target!!! at the bottom.
It has been this way for about an hour.
What should I do?
Should I unplug my phone?
Should I keep on waiting?
I really don't want to end up with a brick.
I disconnected the cable
Kies popped up an error message which said, the upgrade failed and offered to try to recover for me.
By following the instructions on screen I was able to recover my device.
I had the exact experience tramster had. I didn't wait nearly as long however. In all I tried about 5 times. My best theory is a loss of connection through a flaky USB connection. I switched from the front USB port on my computer to the back one.
Eventually it crashed during an emergency reset. I thought I was in trouble. I the emergency reset again, which completed. I was shocked to see that it didn't revert to the previous version, but installed the update instead! bonus.
Another Kies problem; long file extensions. Remove or rename all files with a period (.) followed by more than 16 characters. This is particularly common with imported music files. "Dance by Dr. know featuring RX-man" for example has what the device sees as a very long extension. Remove the Dr. and you are good to go.
Connect in USB mode on the computer and do a search for *.?????????????????* to find all the offending files. I found.one.file.that.had lots of periods. That won't be a problem though because none of them are longer than 16 characters.
If you are encountering issues or lack of update make sure that your Kies window is maximized before proceeding with the update. The hidden popups do happen and you will otherwise not be able to find them. Once the window is maximized the popups get focus and you should be able to proceed with the update.
I had faced same problem on Windows 7. Then I tried updating firmware from Windows XP and it worked without any problem.
Galaxy S's are nearly unbrickable, I've never heard of one being bricked apart from the (very few) hardware locked ones. Firmware updates have quite often failed for me and worked the next time I tried. So I would go ahead and unplug it and retry. The likely worst case is that you'll need to use Odin.
