Hi, while trying to flash to 2.0.6

I did the followings:

Odin:
Checked : One Package, Auto Reboot, Protect OPS
OPS selected is : EUROPA_I5508_v1.0.ops
Integrated Package : I5500_MOTAFOCA_BATFIXV2.0.6.tar.md5

Galaxy 5
1. hard reset *#*#7780#*#*
2. Take out battery for 5 sec
3. hold VolumeDown-Center-Power Button (EndCall)
4. Enter in download mode
5. Connect USB cable from PC to Phone

Odin:
detected COM Port
COM Port Mapping : 1 (COM 21) in yellow

Then Click Start:
.
.
<1> StartThread Detected : 1
<2> StartThread Detected : 0
<3> StartThread Detected : 0
<4> StartThread Detected : 0
<5> StartThread Detected : 0
<6> StartThread Detected : 0
<7> StartThread Detected : 0
<8> StartThread Detected : 0
<1>---cannot open the usb serial port. code:32

and it just stopped there for 10 min before I pull the cable and restart the phone.
It didnt flash at all.

Anyone has any idea what did I do wrong?

I had a very similar problem like yours. What I did was uninstall Adroot and re-download a new one and re-install it. After doing so, I didn't have the Force Close issue again and could root my phone
