How can I clean my Windows Phone firmware?

windows phone recovery tool different provider

Hello,

I am new to this forum. I tested the insider preview 10166 on my lumia 735. Today i wanted to go back towindows 8.1. Butr when i used the recovery tool i get an hungarian firmware from T-Mobile. Even the T-Mobile logo is shown when i start the phone. I am not happy with this although windows is in my own language (dutch). Even an hungarian T Mobile app is shown in my live tiles section. What can i do get a clean firmware again.

i already tried that. It says my phone is not supported and i should use the microsoft recovery tool.How on earth is it possible that i get Hungarian T-Mobile firmware on my 735 when i live in Holland. I downloaded the dutch recovery tool, everything is in dutch and it just downloads an hungarian T Mobile firmware.
