HTC One S Bell re-flash to stock topic

Hi Everyone. i have a modified htc one S and i'm not sure what i did to it in the past tbh. but i think my original mods were kinda sloppy. twrp doesnt seem to work right, among other things. I'm looking to revert the whole thing to stock, so i can begin modding from there. in the end i hoped to install an android 5.0 rom as i intend to give this old phone to a friend. i had downloaded Candy5.

here's some info on my phone currently. can anyone advise me as to how i can revert to stock? it's a Bell locked phone, by the way (Canada)
