[HD2 Android NAND Development] babooyagoo:
FOR THOSE EXPERIENCING HTC START SCREEN CRASH

I imagine that most of the people experiencing these difficulties are, like I was, flashing their device for the first time. In addition to the installation instructions as given in the OP, the complete process has the following additional requirements, I've included some helpful (hopefully) hints.

* That your phone has, or has been unlocked to have, the full 576mb of RAM that are onboard both the T8585 and TMOUS versions of the device. MAGDLR will not boot properly without it, this is the reason you are getting the HTC screen.

* Unsure what T8585 and TMOUS are? That's the model type of your phone, you can figure out which one by looking at the hard keys. All white keys? Your phone is a T8585. Coloured keys? Your phone is TMOUS. If you are aware that your device is a 'pre-release' version of the HD2, the Android release will not work for you as I understand it. It lacks the RAM.

* That dictates which RADIO you should install on your device, choose from the list here. I would recommend Leo_RADIO_2.14.50.02** for T8585 devices. Regardless of your model you must have a radio numbered x.yy.50.zz**, where the x and zz can be any number, but yy must be above 07. TMOUS RADIO releases have TMOUS in their name, as found in the list.

* If you have not ever updated your RADIO, as in your phone is exactly as it was when you opened the box, then your installation of Android will likely fail and leave you on that HTC screen.

* Then, to ensure you unlock the full 576mb of RAM, I would recommend installing Duttys HD2 ROM.

* To install the new RADIO and Duttys, follow the instructions in found in this excellent tutorial. Before trying to install the file you have just downloaded, and Duttys, you MUST install HardSPL as described in the tutorial. The tutorial also takes care of the RADIO INSTALLATION.

* For the purposes of this tutorial, Duttys is your 'preferred ROM'.

* If you have installed the new RADIO (picking one as described), and installed Duttys, you can be 100% confident your RAM is fully unlocked.

* Then, and only then, can you be entirely confident in your Android installation, following the exact instructions in the OP, including the instructions for MAGDLR using the latest version as found in the MAGDLR link.

* If, at any time, you find yourself stuck then you can install a stock HD2 ROM by restarting your phone, holding the volume rocker down while it boots up. That boots the phone into the tri-colour mode that will allow you to install a Stock ROM.

* Stock ROMS are available on the HTC website here. You must pick the correct one for your service provider, if there is not a particular one for your service provider, pick the generic one whose title is not appended with 'T-Mobile' or 'Orange' or something similar. This process is exactly the same as when you have attempted to install MAGDLR, Duttys HD2 ROM and so forth. DO NOT DO THIS UNLESS YOU HAVE ENCOUNTERED THE HTC SCREEN CRASH AGAIN. If you've done things properly up until now, you really shouldn't have hit that screen again. You have done something wrong, probably, go back to the start.

* If you encounter the 'Error Description: USB init failed Info: .\RSPL\RSPL.cpp (723)" error then your phone isn't being picked up properly by your PC. Just unplug, restart the phone holding down the down volume button, connect to your PC, wait 30 seconds or so, and retry the step you were at. Get the problem again? Some have suggested trying a new/different cable.

This is all, obviously, based on my particular experience, but hopefully it's useful.
