[Q] Flashed wrong kernel and relock simlock topic

Hi,

I have had unlocked HTC One Sprint and I used to use it with various roms such as Cyanogenmod and ViperOne. Today I accidently flashed Verizon AOSP kernel instead of Sprint kernel. Now I am having cellular connection issues. I have no connection and I am getting invalid card please contact customer care error in sense based roms. I think somehow I relocked my simlock by flashing wrong kernel and I have tried everything to solve this but I couldnt. Any idea to solve this problem?

Thanks in advance.
