W810i Unlock help

After I read a lot of threads on this site I was finally able to unlock my W810i (T-mobile). But since I read a lot about debranding too, I also wanted to try that.

The sad thing is ofcourse, my unlock was undone, so I had to unlock it again. But the patches didn't work anymore. I already generated a couple of patches, but none of them seem to work; they all give me an error: contact your service provider. I've tried so far; R4EK001 FS_AMERICA_2 + R4EK001 MAIN GENERIC,
R4ED001 FS_EUROPE_3 + R4EA031 MAIN GENERIC, R4ED001 FS_EUROPE_3 + R4EK001 MAIN GENERIC.

So far I only have had succes with R4DB005, the one that came with my phone, but this firmware version doesn't support flashmenu's.
Could someone tell me what I'm doing wrong here.
It just keeps saying; Configuration Error. Please contact your service provider or service center. :(

At first it worked, but now it seemed to have screwed up. Maybe some old files remain on the phone and are messing this up or is that impossible?

Edit: If someone has a solution to this problem, thnx alot. But could you also consider that I am Dutch and I would prefer Dutch firmware over English or Russian ;)

That error caused because you didn't finalize flashing.To do that you need 1 more file-CUSTPACK , and for Dutch you need FS and Custpack EUROPE_3 English - Danish - Dutch - French - German for your firmware,because Main and FS must be same (R8BB01 or something similar)

Oh, thnx a lot man. I finally got it working now. But I now flashed the R4EA031 MAIN and the R4ED001 FS_EUROPE_3 + CDA102494_75_R3A_Generic_Trade_Netherlands and I've got it working now :D. But you say that I need both the same MAIN and the FS, cause actually I want to upgrade to the latest firmware R4EK001 MAIN + R4ED001 FS_EUROPE_3. But you say that isn't possible? Or is it useless for me to upgrade?

Main and FS MUST be the same , or you can get problems after some time
And Main & FS you have R4EA031 and both CID49 & CID50,dependes of your phone
