[Galaxy S II Q&A, Help & Troubleshooting] GuestK00202:
So I just got this phone today. I noticed Cyanogenmod 7 Supports this device and they have a stable build. Was like hearing My b-day was tomorrow. I got excited and started reading the Full update Guide just to see if some steps might be different then the Vibrant and Galaxly S 4G. I wasn't going to worry about a backing it up because simply.....this is a brand new phone just taken out of the box. There was nothing to backup, however there's allot I'd like taken off (Bloat)

The following steps are what I have completed:

Green = Steps I've done.

Red = Steps I haven't done.

Installing the ClockworkMod Recovery

If the Samsung Galaxy S II already has the ClockworkMod Recovery installed, skip this section.

Warning: Installing a custom recovery image on the Samsung Galaxy S II will void the warranty.

Download codeworkx's kernel with the ClockworkMod Recovery and the Heimdall Suite:

Power off the Samsung Galaxy S II and connect the microUSB to the computer but not the Samsung Galaxy S II.

Untar codeworkx's kernel into the Heimdall directory.

On the computer, open terminal and run the following command from the Heimdall directory:

A blue transfer bar will appear on the phone showing the kernel being transferred. The device will reboot automatically.

The Samsung Galaxy S II now has the ClockworkMod Recovery installed. Continue to the next section.

======================================================================================

The phone then went into download mode, while in download mode it changed to this...

Now This is where I stand:

Cannot boot into Recovery

Cannot boot into Download Mode

Cannot flash anything using Odin

No button combo's help get into anything

Phone will not boot normaly

The only 2 things I have yet to try:

A MicroUSB Jig (Which is in the mail as I type this)

A ROM that could possibly be loaded using Heimdall

What is a brother to do!!
