Windows Phone 7 custom ROM development got a big boost today with the advancement in two areas:

  • Custom ROM Image Editor (by AnDim)
  • Mixing of HTC ROM images & different radios (by

The former is what you see above and is basically a simple GUI for manipulation of ROM images, making custom ROM development that much easier. Basically it allows for the "...extraction, replacement, addition, removal" of ROM files. This is still in testing and therefore limited (only read and extract functions) but it's a big step in the process.

The other news comes by way of XDA member A few days ago, he garnered some attention by successfully swapping ROM images from one HTC WP7 device to another. Today, he has gone further by manipulating radio images as well. He notes:

This is a custom ROM not signed with the new and yet not completely hacked MS WP7 signer. If this is true for all operators and spl's then the game just started.

...Now there is a way to flash only the radio from other operators

Once again, for practical matters, this means little for even those who are itching to flash a new ROM. What it does mean is that progress is being made to allow custom flashing of different regional ROMs, radios and mixing and matching. Although significant, we have to wonder just how much improvement will come down the pike from such maniuplation. Still, it's fun to watch as we know these guys will keep at it, no matter what obstacles they face.
