[Q] odin says" Can't open the serial(COM) port." and fails to flash recovery.tar

Did you install the usb drivers first? If not here:

that could be the only reason i can think of that odin isn't detecting phone. Also try a different usb port on the computer, and if that doesn't work try a different cable.

Kies could be interfering with Odin ...

I too was having "Can't open the Serial COM". Kies was interfering.

Go into Kies, Tools -> Preferences, unselect "Run Samsung Kies automatically when a device is connected", save the change, close out of Kies, and then restart ODIN 3. Try flashing now.

reinstall drivers with KIES. go to troubleshoot and then you should be good to go after. also check the cable too..

also sometimes you have to try a different version of odin before it works it happens to me alot. one odin wont work but another does. it's crazy.

Can't open the serial(COM) port Error

I had the same problem and I fixed it by exiting from Kies software. You might get this new error "Complete(Write) operation failed". Then all you should do is just pulling your battery out and restarting odin and phone. I disables the firewall too, but I don't think the problem was firewall. Anyway mine is working well and I did it.

Hi, I'm also having the same problem. The 'Charging paused...' message kept popping up so I tried to flash a different official rom via odin (I was on official ICS). Unfortunately the flash failed and now when I try to turn on the phone the 'Firmware upgrade encountered an isuue......' message comes up. I tried connenting to kies also but can not to do so. I have hope as i can get into download mode but can't flash a rom. I got halfway once then suddenly it failed again. Your help is much appreciated. Thanks in advance.

This worked for me

I had the same exact problem (but this was on my Galaxy Y )

What I had was an old version of KIES (~ 2011 ).

Steps :

1) Uninstall the old Kies
2) Download the latest Kies (2013)

The phone needs to be in download mode for Odin. And kies shouldn't be running on your PC. Go to task manager and kill any kies processes.

Download mode on the phone as I remember is power button and volume down.

Darth · Feb 1, 2015

If anyone is using Odin to flash 4.1.2, I found either Odin 3.04 or to be the only ones that worked for me.

Try different Odin versions perhaps. Uninstall Samsung drivers and install the newest kies again to reinstall them. Don't need to uninstall kies , just be sure all its processes are killed in your PC task manager.

There's nothing you can do until your phone and Odin are communicating. Try another cable, try another USB port on your computer. Last, try another computer.

Try everything I suggested. Otherwise, I'm out of ideas unfortunately.

I'm curious, what does your phone show as in device manager in pc when connected? Or is it not being seen at all?

And Y Duos? You know this is the Tmobile S2 section, right? ?

Darth · Feb 1, 2015

Lots of Y Duos bricked talk here as well as other links in this thread to review.
