Need to go back to original T-mobile WM5 ROM, is that possible?!

---

I've searched the forum and the wiki, and there's is still a very good chance that the answer to my question is out there, but couldn't find it, so here it is:

I flashed my phone with one of the WM6 ROMS found in this forum and it all works great. Unfortunately, I have some hardware problem, so I want to bring the phone in for repair at the T-mobile shop... They don't really need to turn on the phone to fix the hardware I guess, but nevertheless I'd rather have the original T-mobile Dutch ROM restored before I send it in. Is that at all possible? I've seen a lot of posts referring to websites where you can get a complete original ROM and just have to flash it, but T-mobile only provides updates as far as I can see. Can anyone help me?
