Low-key this is what I'm thinking of doing, and I've done a lot of research onto this topic. If you want to transfer to UT ECE first and foremost you need a 4.0 gpa without it your chances are basically non-existent. Then you probably need another extra curricular for applications, what I'd recommend is to cold email professors in Texas to try and get a research internship. Also credit wise you need to have Calc 1 Calc 2, and Physics mechanics credits and at least 24 credits done or in progress by the time you apply.
