You are lucky I looked at this thread at all. The title subject is specific to "M8 eye" which is technically a different from (different hardware) from what you have (the "standard" M8). I don't personally own the "eye" (just the "regular" M8) so rarely look at or try to help on such threads. But I can see how that difference (eye vs. standard M8) is confusing, especially since English is not your native language.

I suggest you flash the stock RUU. Although the RUU for your current version (4.16.1540.8) does not have a working "official" link anymore (old version, Lollipop) that I can find. You can use the newer (Marshmallow) RUU, which you may want updated version anyway. That RUU link is still working:

http://dl3.htc.com/application/RUU_M8_UL_M60_SENSE70_MR_BrightstarUS_WWE_6.12.1540.4.exe

However, this RUU will have some extra steps, as running the RUU will require you first update to the Marshmallow firmware 6.12.1540.4. You can find the firmware 6.12.1540.4 and instructions to flash on the following post (suggest using fastboot method to flash firmware).

Note that firmware is not the same as the RUU (or ROM). Firmware is just a small zip file that needs to be flashed, before the RUU will work (requirement specific for updating to Marshmallow RUU from a lower version). So you need to flash firmware and flash RUU. And hopefully, this will fix the baseband issue.

Also note, that since you are s-off, no need to lock the bootloader to flash firmware or RUU (even if the instructions say to lock the bootloader).
