This will upgrade your Dell Axim X5 Pocket PC to Windows Mobile 2003. It can also be used to recover a bricked or dead PDA. I have not been able to find this anywhere else. The files are original and untouched. Click the screenshots for a full image.
This is Spiaatie's Windows Mobile 6.5.3 ROM for the HP iPAQ HX2000 series. It should work fine for any model. I have tested it on my hx2795b. This is very hard to find elsewhere. As always, the files are untouched and original.
