Won't unlocking the bootloader make banking apps not work anymore? Had this issue when I tried LineageOS on my old phone, and I really like the convenience of those apps as opposed to using the website, which is extremely bad.
Also, how do I do all you said above? (I need a step by step tutorial). Also is it reversible? Are there any other security implications?
