New Update on the Windows Phone 7 ROM Leak
Posted May 18, 2010 at 11:04 am by ElCondor
Since the new Windows Phone 7 ROM for the HTC Mondrian leaked out, many developers have been working very hard on dumping the ROM.
The tools we currently use for Windows Mobile didn’t seem to be working with this completely new WP7 ROM.
XDA developers l2tp and Da_G have managed to dump the ULDR, XIP and IMGFS. The IMGFS is the most valuable and desirable part of the ROM. The compression method used for the ROM, called XPH, caused the problem that we couldn’t use existing tools for dumping it.

I’m trying to dump imgfs partition, found that XPH is a bit modified XPR, changed IMGFS header to XPR and mamaich’s imgfstodump worked ok but produced dump is almost full of zeroes. the smallest files like .lnk and .png and some .dsm are dumped correctly. i think that XPH uses bigger block size while compression than XPR, so if we have sources of imgfstodump and also cecompr.dll from xip dump we can try to reconstruct the algorythm, it does not differ very much from existing XPR.
p.s. all imageinfo.bin seem to be dumped correctly using default imgfstodump.
The developers will continue working on the dump, trying to figure out how it works. They also discovered this interesting registry edit:
Those red words refer to the 1,3 Ghz processor from Qualcomm. This device really is going to be a beast! Check out the thread for more information, but please refrain from posting in the thread unless your posts are useful for the developers.
