Huge m6sp problem- DFU and everything tried

Hi, some days ago I accidentally formatted my player when I turned it on. I only have some minutes until I'll be gone for 5 days, so I'm writing this fast.

I think I pressed the >>| button at the loading screen, then it said formatting. When I turned it on it would say "no resource".
So today, when I finally had my pc, I connected it and formatted it again, to erase bad data. Then I copied m6.ebn and resource.bin 2006sp on it and plugged off.
Unfortunately, this only resulted in an even worse problem, now the loading screen is followed by a bad screen (white) and I have to reset by pressing [enter] for ~30 seconds.
So d/led DFU and used it successfully with 2006sp. It stuck at the enumerating process so I deplugged it, but the white screen was still there.
So, same with sp1009. After about 5 tries where it would always tell me that it couldnt connect (yeah, i pressed m and play), it finally worjked. It, again, stuck at the enumerating message but my search showed a lot of topics where ppl said it was a usb2.0 bug.
Now it's really really bad. I can press play and the short flash shows up, but then it jusrt stays black. I can't even see the flash when I press play and have to enter-reset.
Tried to foormat it with |<< but impossible. FAQ says I need to copy firmware b4 but how if DFU not working???

Are you absoloutly sure your player is a SP version? It's probably an SL if you got it recently, but if it is an SP try following the guide in my signature, and skip right to part 3. Don't use the DFU Tools that you got, download the one attached in the guide, as that is already set up the way it should be. If however your player is an SL, go to the bottom of my guide and I have provided a link for a SL DFU Tools guide. Hope this helps!

Thank you a lot, mbarry!
I've read your helpful thread many times but overlooked your pre-configurated DFU tools. I tried them 3 times and the last one worked.
