Default [TMOB101]Wi-Fi not working after trying s-off

Hi guys,
i moved from nexus5 to M8, TMOB101 bought in Germany.
i've been reading and trying to s-off the devices, without success.
i got back to the stock rom, well, the stock tmob101 rom, but the wifi doesn't start anymore - any hints ?

Thanks !

Can be deleted, problem solved!
