I was messing around with my phone and wanted a custom rom? I guess and I have twrp and I accidentally deleted my whole operating system on my phone and after hours of trying to get everything back I flashed a """Stock recovery nandroid backup"""" for Telus but its always laggy and whatnot. So I was just wondering if there is an ACTUAL backup of a stock telus operating system that I can recover to my phone instead of using a stock nandroid as a custom rom. Thanks. I've already searched everywhere on this site. I would love a ontario telus with nothing changed to it and if anyone has that where they haven't changed it, could you please upload it and share it with me please. I just want my phone like it came right out of the box. Idk I'm weird and it just feels different like its still missing the original and im just running something like novalauncher or something. Thanks.
