I've tried doing this. I shut my phone all the way off, then pressed green + VolUP + Power. I released the power while still holding down the other two, and it still brought me into the Android System recovery instead or the CWM recovery..
I know I've gotta be doing something wrong, maybe someone can shed some light on this.
EDIT1: I'm currently in the process of ShinySide's alternate process. I downloaded the .zip, extracted it, and powered down my phone. I then held the Red + VolDWN + Power button for 13 seconds(Just to make sure) and plugged it into my computer. I ran adb-windows.exe and got a window full of text which then promptly closed(I imagine it's supposed to do this). I then ran fastboot-windows.exe and got a similar result. I then double clicked on the install-recovery-windows.bat and this is the screen I see:
it's currently stuck here and I'm going to disconnect my phone, remove the battery for another 13 seconds, put it back in and then reboot. I'll post back here in a minute(via an edit to this post) informing you what happened.
EDIT2: When I removed the battery for 13 seconds and simply pressed the power button, then it booted as normal. no android system recovery screen. When I then shut is back off and booted into recovery, it brought me back to the standard android system recovery screen where the only options I have are the following:
reboot system now
apply sdcard:update.zip
wipe data/factory reset
wipe cache partition
touchscreen firmware update
I'm all out of ideas now... Help?
EDIT3: Sorry for the double post, that was unintended.
