WM2005 upgrade - stuck at bootloader

For some unknown reason my WM2005 update crashed and left my x50v stuck with no ROM image. I CAN get to the bootloader, and diagnostics, but that's it.

Could someone be so kind to help me with a ROM image so I can flash from the SD card? I tried making my own from the IMG file I have but no luck :(

Please?!?!!!!

I found some images, formatted my card with FAT32, but the bootloader never shows those images and lets me select any of them. I really am stuck now, and the x50v is out of warranty. Please, does anyone have any idea? I wish I hadn't bothered trying WM2005 now
