S-Off Htc One Mini ??

Hi guys

I’ve been trying to find a recovery or stock firmware for my phone but it seems like it doesn’t exist (see my other thread).

So now i’m trying to find a way to achieve S-Off so that i can change my CID and MID and flash a firmware from another network.

I’ve tried rumrunner but it wasn’t able to do it and said something about my rom not being supported.

The phone is unlocked and rooted and has twrp recovery and is on bootloader 2.22.0000.

Does anyone know how i can get S-Off ?
