Samsung - Protocol error with Heimdall

Galaxy Tab 10.1 Q&A - xda-developers - forum.xda-developers.com
Hello!

I have Galaxy Tab GT-P7500, Android 3.2 and I want to flash CWM and CM. I followed guide how to flash on CM site. Problem is, that I got stuck in first step, flash recovery.

I got to download mode, on screen is written ODIN3 Download mode (protocol v2.1). Then, I install driver with zadig tool with success (my device is callde SEC DEV and I don't know why) and run command

Code:

heimdall.exe flash --recovery zImage --verbose

Here is output:

Code:

ERROR: Failed to initialise protocol!

I tried to do this procedure on 4 computers (in two of them there were no Samsung drivers at all, winXP, win7), I have original USB cable, I tried Odin, that didn't detect my tablet at all, I tried google for 4 hours without success. I tried everything. Be sure, that I know what I'm doing, because I flashed around 10 phones and two tablets for my friends, but I never got so stuck.

So, here is my question. Is i tossible, that my download mode has new protocol, that Heimidall can't handle? And is there any solution for this situation?

Thanks for any advice,

Ales
