Root [T-Mobile] HELP: Root failure?!


Well-Known Member
Bored of waiting for TMobile UK JB update so have finally got round to rooting the phone.

However. It hasn't worked and now its completely dead.

ODIN says this:
<ID:0/008> Added!!
<ID:0/008> Odin v.3 engine (ID:8)..
<ID:0/008> File analysis..
<ID:0/008> SetupConnection..
<ID:0/008> Can't open the serial(COM) port.
<OSM> All threads completed. (succeed 0 / failed 1)

The TAR file is this one: CF-Root-SGS3-v6.3.tar

Please help, no idea what to do!!

What rooting guide are you following?
You have the T-Mobile version or the international version of the SG3?

Edit: haha..just saw your edit:)

You need to have the phone booted into download mode for that to happen.

Power off

wait till black screen for a few secs

hold down volume, menu bar, power

when screen pops up, let go of the power button and when rest of screen appears, let go the vol and menu btns.

then, connect the usb cable, and then, start the Odin

Good Luck!
