Thanks for your reply. I tried not only 30 seconds but 3 hours with battery pull & "3 fingers salute" but it still doesn't go to nowhere. Could you pls kind to provide step by step to run the Odin recovery? It has been 3 years since I played with those procedures, now I become a noob. Also, the Odin procedure I read only apply to JB but not ICS. I tried some ADB reboot, but doesn't recognized the phone connected to any port.
You can't odin flash a recovery on the I777. I don't know what TheGeekyNimrod was thinking, maybe forgetting that the recovery is compiled into the kernel on the I777.
There are not too many kernels available in tar format for odin flashing. I would suggest that you flash the latest stock firmware I777UCMD8 to recover the phone. You can obtain that in the Download Repository, for which see the link in my signature. I'm putting how to use Odin below.
Once you have stock, use Framaroot with the Aragorn exploit to root the phone, then use Mobile Odin to install the AJK no swap kernel. Both are available on XDA Developers. You can now flash SHOstock3 v4.0, or any other firmware you want.
Ask if you need additional info.

How to use stand-alone Odin3 to flash firmware:
Follow and recheck each of the following steps. Do them in order listed, as some steps are dependent on previous steps. Instructions are for Odin3 v1.85. It should work with any version of Odin, but some details, like color of items, may be different.
1.) Open Odin on the Windows Desktop.
2.) Have the USB cable plugged into USB port on the computer, but *Not* plugged in to the phone.
3.) Shut the phone off.
4.) While holding down the vol+ & vol- keys, plug micro-usb plug into phone.
5.) In Odin, you should get the yellow box under where it says ID:COM with the text 0:[COMx], and in the Message area, <ID:0/00x> Added!! where x is some number, usually 1-8.
6.) In Odin, make sure Auto Reboot and F. Reset Time are checked and all other items are not checked.
7.) Click on the PDA button. Browse to the tar file you want to install (I777UCMD8) and select it so its path appears in the text edit box next to the button.
8.) Make sure the check box next to the PDA button is checked.
9.) Click the Start button.
10.) You should see the green progress bar advancing.
11.) When complete, you will get a PASS (or FAIL if unsuccessful).
