This is a custom recovery based on Cyanogen's recovery source with a lot of things added by me. The purpose of this recovery is to avoid using adb by accessing all features directly from the menu.
v2.3.3 has some screen tearing/color weirdness going on. This is just a graphical bug in the recovery kernel, nothing to worry about. I'll try to fix it in a next version.
- Place PC36IMG.zip on the root of your sd card.
- Boot the phone into the bootloader by powering the phone down, then press the power and the volume down buttons at the same time.
- Once the phone boots into the bootloader the phone will automatically recognize the zip file. It will ask if you would like to update, select yes and let it do it's thing and you will be good to go
