Questions on Switching back to Original HTC ROM, Upgrading Radio

---

I have 3 questions for the forum -

1) Why is it required to do a Hard-SPL and upgrade the Radio before upgrading to a Custom ROM?

2) I downloaded a Custom ROM and after unzipping I saw only 1 .nbh file. To update the ROM do I need to copy this file to the CustomRUU folder? There is already a nbh file present there - do I overwrite it?

3) If I am not happy with the Custom ROM - can I go back to the Original HTC ROM? I have it downloaded. Also - will the Radio be updated back to the Original ROM as well?

Any help is appreciated!!!

1) Read the upgrading guide here and ye shall learn.

2) Yes. Or the other way around (copy the CustomRUU file to the ROM folder).

3) Yes and yes. Stock ROMs usually include Radio as well.

Good luck

Thanks for the response. I did go through that guide. I got the reason for the Hard-SPL - but why the radio? Why do we need to upgrade or change the radio?
