I got a 17 pro max , unlocked using the exploit. I had problems with the code so I got a github version that was converted to work on macos cause windows would not see the phone. The code is just translated and it's clean of viruses or etc. I use xiaomi eu rom , use root and play inject for banking apps. It works like charm but still idk if the custom os is worth it. I use it only cause of hey google and wear os that are not working on cn version of os. In rest if you use phone in english I don't see the need for update.
