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

[Q] odin says" Can't open the serial(COM) port." and fails to flash recovery.tar
hey,...
i am trying to root my tmobile galaxy S2 and i am in downloading mode...put recovery.tar file in PDA section and when i hit start...nothing happens and after a while i get failed notice and says " Can't open the serial(COM) port." what am i doing wrong.

Did you install the usb drivers first? If not here:
http://www.mediafire.com/?6onrjbyd46j4lhj
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.

uninstall Kies if u have ut because the drivers stick i did and now it works lol

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..

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.

Thank You.

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.
?

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? ?

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

1.Try to redownload the firmware that you've flashes and flash it again if it will help.
Troubleshooting Instructions:
"USB Driver Not Recognized" Problem ?

1.If your USB Driver is not recognized , Open Kies on your PC/Laptop then click "Troublelshoot connection problem" button , It will reinstall the USB Driver named "SAMSUNG USB Driver for Mobile Phones" . Wait until it finish .
2.Uninstall Kies and the USB Driver named "SAMSUNG USB Driver for Mobile Phones" on Add and remove programs on Control panel , Then after you install Kies again then do the directions on Step 1 installing your USB Driver.
3.Try Redownloading Odin v 1.85 , Click on my attachment to download.
4.Make sure your Kies is up to date.
5.Make sure that your battery is 100 % fully charged
6.Remove your SIM Card before flashing , That could interrupt the flashing process.
7.Press Ctrl+Alt+Delete and go to Processes and terminate the process named "KiesHelper.exe" and "KiesTrayAgent.exe" and if you're using ADB then terminate the process named "adb.exe" ( Im not sure if adb.exe is the correct name of ADB process,Correct me if im wrong)
8.Make sure before you press the "Start" button on Odin you should Notice these two thing before pressing the Start button : ID:COM and make sure you have got the "Added!!!" word on the box (Where you can see if flashing has successful ex. Success 1/0 Failed

reset, reflash ton of roms, not efficient
I think driver doesnt play a role in this, with a non driver install PC I still can mount sdcard as removable disk drive with other phone
maybe a hardware problem?

One thing you can do is that when you plug your phone ... delete all all the devices with "Q" on it in your computer device manager.
then unplug and try plugging back.
sometime happens when window install other drivers for one device it stay stuck with it until you manually delete those drivers. Maybe thats the case. Your friends device id is configured with right drivers. You can also switch to another computer and install drivers there and check.

I have to confirm once more that this problem is not driver problems because it's not necessary driver when mount sdcard (test with other lu6200, other android model with non-driver PC)
I think my problem is hardware error or some wrong IMG is flashed in one strange partition (not system.img or baseband.img etc...) during my massing times of flash new rom

When device is connect is doesnt go in Connected as media device (MTP)

This is weird my note one always pops up with a windows folder and I just drop my new rom in there but my new I317 when I connect it to the computer is doesnt show up. It will charge the device but does let me get into it so I can drop my rom in there and install any ideas? I did a factory reset and I have all the drivers installed.

Its did work when I changed them both to pda....I also stopped windows from searching for update for driver....You can then go to device manager see the error on usb com ports and direct which drivers to install from there...When I swtich to modem tho I have to do the drivers thing again.
I remember seeing a post to stop windows from installing thier own drivers just cannot seem where to find it

I installed Busybox Free on my phone (using the simple installer) and it allows my phone to connect to the PC just fine. I also have downloaded Samsung's drivers to my PC.

[Q] Galaxy Ace II cannot be detected by PC (XP/W7/W8)

Hello, I'm the new guy, kind of (I'm new to this forum but somewhat a technological handyman, so to speak).
I had recently obtained a Samsung Galaxy Ace II, everything was going good on the phone, hell, it's what? Two years old now? Anyway, I noticed the immense trouble I've been having trying to get several Windows PCs/laptops to detect anything from the phone, no driver updates, installations, not even from the trustworthy SAMSUNG Kies application. It is becoming a real problem as I really want to keep this phone, root it, installing several ROMs as I go along, but no, the computers won't even allow me to access the contents of my SD card through USB.
(Note: I have manually downloaded and installed SAMSUNG USB drivers and pooft, still nothing!)
I have tried quite a few methods to allow the PCs to establish a connection with the phone e.g. Dialing "*#7284#*, accessing "PhoneUtil", choosing "PDA" as the good mode, even switching to "MODEM" then back to "PDA"; Uninstalling/Reinstalling drivers; Attempting Kies.
I guess I am on the look out for a new-ish phone to replace this, which saddens me as I love being able to root, install various ROMs, Kernels etc, personally I like this phone too, more than my Spica running ICS (couldn't be too hard though, it wasn't stable whatsoever).
If anyone on this board could find a solution to this problem for me, I would be ever so grateful, I don't doubt it though, I love the work of XDA. Thank you.

Turn off the phone with no cable attached, press volume down, home and power at the same time and then volume up to put it in ODIN mode and connect it to the PC (use windows vista or newer so it auto installs the driver) It should install something like Samsung USB serial device. Tell if it works

Do I have to load it into ODIN mode whilst Odin is running on my PC?

For this test you dont need ODIN on the PC. Its only to see if the PC recognizes the phone

I just tested this and it appears not to be working, whatsoever. Is it necessary to have all SAMSUNG USB drivers installed on the PC?

Windows should auto install the drivers. Connect the phone to the PC and see in device manager if there is something like an unknoen device or Samsung USB device

Thank you for the help, although my problem is not dealt with still. I have completed the steps that you had suggested, thoroughly and repeatedly, yet there is no hope for a permanent, or even temporary fix for my mobile.
Windows isn't displaying any correlation between my PC and phone, no driver software auto-installs and no sign of the device being located in the Device Manager, not even under an "Unknown device".
Is this a problem for most Ace II devices? Or am I missing something that is too obvious to consider so seriously?

Porobu once told me something like:
1. Uninstall kies and sammy usb drivers
2. Install kies again, it should promt to install USB drivers.
3. Plug in phone to pc in DL mode.
I'm not sure what you mean in your 1st post so im assuming you have yet to try this. Works for me

When do I plug the USB into the phone and boot my phone into download mode? As soon as the drivers are installed via Kies?

After kies installation complete(dont have to open), boot phone to download mode, connect to cable and plug to pc

It sounds like a broken microusb port but try something first.
Download ubuntu or any other live cd linux distro
Boot it on your pc. You dont need to install anything.
Open a terminal
*Plug the phone while it is turned on to the PC
Write in the terminal 'lsusb' without the quotes and press enter
Something like Samsung android device or MTP device should appear.
If it doesnt appear power off the phone and go to odin mode and repeat from the * the steps
