I always get the willies when I read, "I dl the pc36img". Let me explain something here.
The PC36IMG.zip is a moniker that tells the HBoot to test it and install the contents after asking the user.
There is NO gurantee as to what is wrapped up with that filename. Unless you know what it is you have downloaded, open the zip file and look inside.
A ROM will be 175 to 200 mb
Recovery will be around 4 to 5 mb
A standalone radio will be 150 to 170 KB

But you can put anything on that file. What it does is circumvent the need to use recovery. Before acquiring Root, this is what you are limited too but once root and a Recovery Shell, you don't need to use PC36IMG and I would recommend staying clear of them.
Also, if you install a Rom with the PC36IMG wrapper, rename or delete it after a succesful flash, lest you will experience a significant delay while the zip file is being interrogate upon all subsequent reboots (and it is all to easy to accidentally reflash that Rom- ugh!)

THis is not to say that there is no use for PC36IMG. There is and I post them from time to time though I have stopped posting them by that name. I instruct the user to rename them to PC36IMG. That way they know what they are installing and understand the process. And if they have a working recovery shell, they don't need to use the HBoot automated install system.
